One month into the war in Iran, a growing shortage of crude oil is threatening to morph into something worse: a shortage of nearly everything.
The conflict in the Middle East has crimped oil and natural gas flows through the Strait of Hormuz, reducing global supply by about one-fifth. The disruption has not only sent fuel prices soaring, but has squeezed supplies of petrochemicals needed to make everyday items like shoes, clothing and plastic bags.
That strain is now spreading into every corner of the consumer market as prices rise for materials like plastic, rubber and polyester. The impact is so far most evident in Asia, which accounts for more than half of the world’s manufacturing and is heavily reliant on imports for oil and other commodities.
In South Korea, where people have been panic-buying trash bags, the government has encouraged event organizers to minimize use of disposable items. Taiwan has started a hotline for manufacturers that have run out of plastic, while its rice farmers told local media they may hike prices because they can’t get vacuum-sealed bags.
In Japan, the oil crisis has sparked fears that patients with chronic kidney failure won’t be able to get treatment due to a lack of plastic medical tubes used in hemodialysis. Malaysian glove manufacturers say a dearth of a petroleum byproduct needed to make rubber latex is threatening global supplies of medical gloves.
“This spills into everything very, very quickly: beer, noodles, chips, toys, cosmetics,” said Dan Martin, co-head of business intelligence at Dezan Shira & Associates, an advisory firm that helps international businesses expand in Asia.
That’s because plastic caps, crates, snack bags and containers are becoming more difficult to procure. Petroleum derivatives are also needed to make adhesives for footwear and furniture, industrial lubricants for machinery and solvents for paints and cleaning processes, Martin added.
“It’s very fast transmission from oil and shipping disruption into petrochemicals and consumer goods,” he said.
The upheaval across commodities and manufacturing is putting upward pressure on global inflation and weighing oneconomic growth. Manufacturers are paying more for energy and raw materials, which is hitting profit margins and starting to push up prices for consumers. Rising fuel costs are upending travel and logistics, while tight supplies of other materials from the Middle East, such as fertilizer and helium, could lead to more expensive food and electronics.
“Such complex spillovers confront us at a time when many economies have limited room to absorb shocks,” the International Monetary Fund wrote in a blog post Monday. “Although the war could shape the global economy in different ways, all roads lead to higher prices and slower growth.”
Countries have begun releasing a historic amount of oil from emergency stockpiles to offset the war’s impact. But much of the broadening supply crunch stems from a shortage of naphtha, a petroleum by-product and critical feedstock for synthetic materials, of which producers have far fewer reserves and no substitute.
Some petrochemical companies in Asia, which gets more than half its naphtha from the Middle East, have cut output or declared force majeure in recent weeks due to limited raw materials. Force majeure is a legal term that refers to unforeseeable circumstances preventing a company from fulfilling a contract.
South Korea has taken advantage of a suspension of US sanctions on certain Russian oil and petroleum productsto buy its first load of naphtha from Moscow since the start of the Ukraine war. Seoul has also imposed an export ban on naphtha to preserve domestic supply.
Martin at Dezan Shira & Associates, who works with manufacturers in Vietnam, said the scarcity of naphtha is leading to higher input costs for clients, particularly those that make products with strict specifications, such as semiconductors, automotive parts and medical or food-grade packaging.
“There’s not really a whole lot of recourse, except to go and cut assembly and use less power,” he said. “All companies are competing against each other. Everyone’s in the same exact position.”
As producers rush to secure materials, the costs of plastic and products that contain it are climbing. According to ICIS, a commodities market intelligence platform, prices for plastic resins in Asia have risen as much as 59% to record highs since late February, when the United States and Israel first launched airstrikes against Iran.
One of Thailand’s biggest plastic packaging wholesalers said it has increased prices by 10% for the clear cellophane bags widely used by restaurants, food stalls and for take-out deliveries. Indian media has reported that bottled water is getting more expensive, with prices for plastic bottle caps quadrupling since the war started. And an official at Nongshim, South Korea’s largest instant noodle manufacturer, said the company that supplies its plastic packaging currently has about one month’s worth of supply left.
Shariene Goh, a senior petrochemical analyst at ICIS, said consumer goods that rely heavily on plastic packaging, like cosmetics, may be even more prone to shortages than some products with plastic in them.
“The end-products segment might leverage their inventory levels, which might deplete over time,” she said. “I would think that they might start to run out pretty soon.”
As the first region to feel the impact of the fuel crisis,Asia’s new supply issues bode poorly for the rest of the world, if oil and other resources can’t be produced in or shipped from the Middle East.
Aside from producing about 17% of the world’s naphtha and 30% of its plastic resin, the Middle East also supplies 45% of its sulphur, used to make fertilizer, 33% of its helium, used in semiconductors, healthcare and aerospace, and 22% of its urea and ammonia,used as nutrients for crops, according to Morgan Stanley.
US farmers are already paying more for fertilizer as the price for imported urea has risen by about one-third since the war began. In India, condom manufacturers are reporting disruptions from shortages in not only packaging materials and silicon oil, which requires petrochemical feedstocks, but also ammonia.
“Much like during COVID, the shock unfolds sequentially rather than simultaneously – a rolling supply disruption moving westward,” J.P. Morgan analysts wrote in a research note last week.
For the past few weeks, Asian countries have been focused on mitigating oil price spikes, with measures such as releasing oil stockpiles, capping fuel prices and cutting work hours to save energy. But according to J.P. Morgan, the supply constraints will become more severe in April, with the last of the crude deliveries sent before the war due to arrive at the beginning of the month.
“The primary challenge has shifted from price to physical scarcity,” the bank’s analysts said. “Asia is no longer in a purely preventive phase.”
Analysts said some producers of consumer goods are delaying materials purchases in the hope that prices will fall if the conflict in the Middle East is resolved.
Qiu Jun, a 36-year-old polyester maker in the eastern Chinese city of Haining, said that, since the effective closure of the Strait of Hormuz, the price of the polyester chips he needs to make his fabric has jumped about 50%, a hike his clients in home textiles, apparel and yarns industries aren’t willing to swallow.
His factory of one dozen employees is still running, but only to fulfill existing client orders. He said he is taking a wait-and-see approach to avoid overpaying for materials to produce unwanted stock.
“I’m anxious,” Qiu said. “The whole industry feels the same. No one knows how the war will play out.”
Others are trying to cut costs by minimizing the amount of plastic used in packaging. In Indonesia, where plastic prices have doubled in the past month, companies are reducing the thickness of packaging material, according to the Indonesian Packaging Federation. Some are even considering using different materials, such as paper, glass, aluminum or recycled plastics, though the organization said each would pose its own challenges in terms of ensuring durability, compliance with safety regulations and the time needed to rebuild production lines and source new supply – which could take six months to one year.
Turning to recycled plastics could also come at a high cost, said Stephen Moore, founder of MLT Analytics, a plastics trade data platform. He said global supply of recycled plastic material is already constrained, and it generally costs five to seven times more than plastic made from fossil fuels.
“If everything returns to normal in the Strait of Hormuz tomorrow, I think it’s still several months at least until there’s a semblance of normalcy for the plastic sector in Asia,” he said.

Don’t miss the quick guides: “Discovery and demo talk tracks” and “30-60-90 day sales manager onboarding plan”
Amanda Zhu is a force to be reckoned with. As co-founder and COO of Recall.ai she personally closed more than $7M in enterprise deals while building the sales organization that drove 4x year-over-year growth.
Her story is a reminder that the COO role done right isn’t a template—rather, it’s a response to a company’s evolving needs. In the beginning, some companies need to scale customer operations. Others need to build a sales machine. Recall.ai needed someone to own go-to-market end-to-end, and Amanda took the helm. In doing so, she not only helped bring in some of the company’s foundational customers, but also built a consistent enterprise inbound motion and team that ultimately supported a $250M valuation.
Recall.ai is the API for meeting recording. The API captures recordings, transcripts and metadata from Zoom, Microsoft Teams, Google Meet, in-person meetings, phone calls, and more. Recall.ai offers a Meeting Bot API to send meeting bots to calls and a Desktop Recording SDK to build a desktop app that can record meetings.
Many founders act as the company’s first sales rep. But the real challenge is what comes next: systematizing that intuition, scaling hard-won insights, and building an organization that can execute the GTM motion without the founder in the room. Amanda’s experience demonstrates how AI-native founders can close seven-figure deals through rigorous discovery, strategic personalization, and disciplined execution—and then successfully systematize their learnings into a playbook that can be handed off to an independently led sales team.Here, we collected nine of Amanda’s best strategies for AI business to achieve success throughout the sales cycle and the journey of scaling a sales organization.
Top takeaways from this enterprise sales guide
The most important moments in moving deals forward are often between checkpoints. Invest in back-channeling, warm intros, and in-person visits as much as the formal sales process.
Every discovery call needs four things: a clear sequence, incisive questions, an honest qualification moment, and a compelling narrative.
When a deal stalls and you don’t know why, fly out. The goal is to uncover the blocker, not pitch harder.
Design every event and dinner to optimize for the follow-up, not the night itself.
Treat every objection as a missing signal: technical objections hide underlying constraints, financial objections open a conversation about the cost of inaction, and risk objections dissolve fastest on a live call.
When hiring a VP of Sales, prioritize intellectual honesty and critical thinking over quota history—ask candidates to analyze their misses, not just their wins.
Onboard your VP of Sales through maximum exposure before maximum ownership: shadow first, then transfer 1:1s, deal judgment, and board materials around day 90.
Opening self-serve will temporarily tank your MRR. Expect a stall, and trust that higher-fit, higher-volume inbound follows.
Every new product, customer segment, or GTM motion rewires your operating model. Plan for upheaval, not just growth.
Discovery calls that lay the groundwork for seven-figure deals
1. There is no enterprise sales script—only a scaffold
Founders are often told that when it comes to sales, there is no real playbook. “It’s true, there’s no script, formula, or guaranteed sequencing for enterprise deals,” writes Amanda. “But there is a scaffold.”
While every deal eventually hits the same checkpoints—from discovery call to demo to final sign-off—the moments of real importance are harder to define. “It’s what you do when you’re stuck between checkpoints,” Amanda says.
Below is a list of tactics she’s used to move deals forward:
Back-channeling to learn which stakeholders are worried, which are confused, and which might be silently blocking the deal
Flying out when a senior stakeholder joins late and wants to “reassess”
Hosting a small dinner to align teams who weren’t looped in until mid-PoC
Getting warm intros from investors or any mutual connections
Running security and procurement in parallel so they don’t choke the timeline later
Showing up early to events stakeholders are speaking at
Going backwards a checkpoint when something collapses, instead of forcing the next step forward
While none of these moves look like “selling” and may not follow a prescribed sequence, these tactics all nurture relationships and cultivate trust within the process. Amanda emphasizes the importance of lateral thinking to problem solve is what’s necessary to get past thorny sales obstacles.
2. Successful discovery and demo calls have four main ingredients
In the early days of founder-led sales, Amanda tried to compress discovery and demo into a single 30-minute call, jumping straight into feature walkthroughs before knowing whether a prospect was even a fit. Needless to say, this approach didn’t work.
“I didn’t start with great talk tracks,” admits Amanda. “I started by doing everything wrong.”
After hundreds of calls, Amanda noticed that prospects didn’t need a slicker talk track or a more seamless demo. What they actually needed was structure so they wouldn’t get lost in the call and a powerful narrative arc that situated use cases in real-life workflows.
Amanda has now crystallized her approach into four main things prospects need from her:
1. A clear sequence so the conversation doesn’t jump around
2. Incisive questions that get to the heart of the prospect’s problem
3. A moment of honest qualification where you openly tell the prospect if they are a fit or not
4. A compelling narrative, not just a simple product tour
Amanda kept refining her talk tracks around those principles until they became codified.
“If you’re doing founder-led sales, use the structure until it becomes instinct,” says Amanda.
Creating deal momentum where it counts
3. Flying out is about uncovering the real blocker, not pitching harder
Sometimes in sales, it’s unclear why you’ve hit a roadblock. For Amanda, these moments are often a clear signal it’s worth hopping on a plane. Though she never point-blank asks prospects if she can fly out to meet them.
Instead, she says something like: “I’m going to be in Atlanta on Friday from 2–7pm. Could we connect for dinner?” Amands likes this approach because the clarity of the ask signals effort without desperation, while the tight time window reduces back-and-forth and makes it easier for a busy executive to agree.
Once she’s in a prospect’s city, Amanda focuses on uncovering hidden information, not pitching. In one stalled deal, she learned that a decision-maker was quietly leaning toward an internal solution—something that never surfaced on Zoom. Meeting in person created the space for candor, which let Amanda respond by walking the exec through the edge cases, ceilings, and tradeoffs the team would have to deal with. “By meeting the exec on their turf, you have their full attention and don’t have to simultaneously perform in front of their team,” she writes.
Amanda is also deliberate about where these conversations happen, depending on her desired outcome. She finds that offices are ideal for aligning multiple stakeholders, while meeting outside of a company’s HQ is best for eliciting honesty. As Amanda puts it, “The room shapes what people feel safe saying.”
In-person visits have been an incredibly effective way for Amanda to unblock deals, but she has one important caveat: “Flying out isn’t about pushing the deal forward,” says Amanda. “It’s about finding out what’s actually blocking it.”
4. A carefully-engineered prospect dinner can deliver 160x ROI
Last year, Amanda spent $25K on a dinner that brought in $4M in revenue. This was no accident—every single element of the evening was meticulously designed to generate quality conversations that would spur deals forward.
At large conferences, where dozens of sponsored dinners happen every night, the promise of delicious food alone isn’t enough to get the right people in the room. So Amanda booked notable speakers two months in advance, and intentionally name-dropped them in the invites. She was aiming to entice 40 attendees, but was pleasantly surprised with overwhelming demand—pushing the capacity to 90 attendees.
At the dinner, Amanda didn’t leave conversations to chance. A sales rep was assigned to every table with a single goal: get customers and prospects sitting together. That way, prospects heard answers directly from happy customers—not the sales team—and could see firsthand how much customers trusted the team and product.
Even the follow-up was designed with intention. Instead of a generic follow-up email, reps introduced prospects directly to customers in the email, referencing specific conversation topics from their chats at dinner. Reps still requested meetings, but the follow-up led with value instead of a pitch.
In Amanda’s words, “If you want meetings after a dinner, design the dinner for the follow-up.”
5. Enterprise objections are most often missed signals
When a deal stalls in the middle, Amanda doesn’t push harder. Instead, she rewinds the deal to the last checkpoint where everyone was aligned. “In enterprise sales, a ‘no’ isn’t necessarily a rejection,” she says. “It’s often a signal you’re missing context.” In her experience, being given a ‘no’ usually boils down to one of three factors that can each be systematically addressed:
1. Technical objection
For example, “We need X and you don’t have it.”
Amanda finds that this is almost never about the feature. Instead, she focuses on the question behind the question, and asks, “What is the reason you need X?” By understanding the true underlying constraint, it’s often possible to offer a better solution to solve the actual problem.
2. Financial objection
For example, “How much should something cost?”
It’s common for early stage startups to experience prospects pushing back on pricing. When exploring willingness-to-pay, it’s recommended that founders ask thoughtful questions such as what the prospect is using to anchor the comparison and where the budget is actually coming from. Perhaps most importantly, pricing can be an entry point to discuss the cost of doing nothing—which is often much higher than prospects realize. If the champion can’t answer these questions, there’s a clear discovery gap to address.
3. Risk objection
For example, “It doesn’t meet our security requirements.”
When hit with this type of objection, Amanda has had consistent success getting everyone who’s concerned on a live call. Live conversations surface missing context, incorrect assumptions, and what actually needs to change. “Vague risk objections don’t survive real-time discussion,” she says.
Scaling the sales organization by hiring dedicated leadership
6. Ask hard-hitting questions to secure the right VP of Sales
As the Recall.ai has grown, Amanda knew it was time to delegate the sales function to a dedicated leader. At the executive level, nearly every resume was tightly polished and most candidates could pull off an excellent interview, so Amanda needed an alternative way to suss out the VP of Sales right for the team.
Amanda cut to the chase in interviews, asking candidates to dissect and analyze their misses more than highlight their wins.
“I cared less about whether targets were hit and more curious about why they thought they missed their targets,” she explains. “Did they blame the product, the market, or other people? Or did they truly understand what broke and own their role in it?” Amanda was looking for three qualities she couldn’t do without— intellectual honesty, critical thinking, and a growth mindset.
She also relied heavily on backchannel references, specifically from a candidate’s direct reports. She would ask them about where the candidate needed to improve and how they would react when things didn’t go according to plan. One very revealing question she always asked: “Tell me about a time you disagreed with them.”
Amanda would also assess whether or not the candidate could still be an effective seller themselves versus just waxing poetic about sales. She’d use take-home assignments to clearly evaluate their sales capabilities. She had candidates sell to her and put together a sales plan as part of the hiring process. Finally, Amanda would weigh personality and a gut sense of trust heavily in her decision.

7. Maximum exposure is the best way to onboard a new VP of Sales
When Justin joined as VP of Sales, Amanda’s goal wasn’t for him to ‘run sales.’ “The goal was to make sure deals didn’t slow down because every hard call still flowed through me,” she says.
For the first 60 days, Amanda made sure Justin got maximum exposure to the reasoning behind her decision-making. She had him shadow every sales call, daily standup, pipeline review, and deal debate. She even had Justin selling like an AE with the goal to understand the team’s thinking and non-negotiables. “Because that context matters once deals get complex,” says Amanda.
Around the 90-day mark, she started shifting ownership off her plate. Justin took over 1:1s with reps including coaching and feedback, deal judgement, and recruiting workflows. He also handled billing and collections conversations, materials for board meetings, investor updates on sales. “A lot of that work doesn’t look like ‘sales,’” says Amanda. “But it’s the work that keeps seven-figure deals moving without the founder in every loop.”
Through this rigorous onboarding process, Amanda could hand off her responsibilities to Justin—freeing her up to tackle the next priority areas as COO. “The moment I consider an exec fully onboarded is when I trust their decisions when I’m not in the room,” she says. “And that trust only comes from shared context.”
Scaling beyond the first GTM motion
8. Changes to your GTM motion aren’t without risk—but a calculated risk was how Amanda scaled MRR 5X
“Opening self-serve was one of the scariest decisions I’ve made as a co-founder,” recalls Amanda. “Our MRR stalled for a month after launching.” Before self-serve, every prospect had to speak with the team. These conversations provided crystal clear visibility into why people were buying and how they planned to use the product. If MRR slowed, Amanda usually knew why within a day.
But when the team opened self-serve, people could sign up, build, and use the product without ever talking to the team. Usage took off immediately, but for a month, MRR went flat. Amanda and her team had traded immediate visibility for scale.
Amanda was deeply relieved when, with time, the system caught up. Self-serve customers started raising their hands to talk to the team—not for initial discovery, but to get more out of the product. At the same time, larger companies started reaching out after they’d already seen the product work.
This led to more conversations—“just later, at higher volume, and with bigger customers,” says Amanda. This when growth really accelerated and her initial risk paid off beautifully. Since opening self-serve, the team’s MRR has grown 5x.
9. Upheaval is often a necessary part of hypergrowth
The year 2025 was an eventful one for the Recall.ai team. They tripled their revenue, raised a Series B, expanded beyond the meeting bots with the launch of a new product, and launched self-serve. And yet, from the inside, the year was full of change and growing pains. “This was a rewiring year,” reflects Amanda.
A combination of three inflection points in three major areas of the business were hit at once: the product, the GTM motion, and the sales motion. A new product meant major adjustments to how the team pitched the product, allocated engineering time, and elevator pitched the company. The self-serve motion forced the team to rebuild the funnel. Established work on everything from pricing to onboarding to support had to be rethought.
And as the team attracted upmarket customers, the sales motion had to be drastically altered. Typical deals went from single to multi-stakeholder deals. Simple technical validation became multi-threaded reviews and one product fit became cross-product conversations. Amanda’s team had to learn a new type of selling.
Amanda learned firsthand that every new product, every new customer segment, and every new GTM motion changes the operating model. While the team is much stronger for it, Amanda feels it’s worth acknowledging the importance of upheaval.
“It’s a good reminder that companies don’t grow in straight lines,” says Amanda.
As conflict in the Middle East pushes oil prices higher and unsettles global bond markets, emerging market sovereigns are watching two things closely: the path of global yields and the debt coming due on their own refinancing calendar. They cannot set the price of borrowing. But can they choose the timing? That question goes to the heart of sovereign debt management in volatile global markets.
Emerging market debt has surged since the pandemic, renewing concerns about rollover risk and fiscal vulnerability (Rogoff et al. 2021). More broadly, recent evidence suggests that dollar use in international debt issuance has returned in waves rather than followed a one-way trend (Pradhan et al. 2026). Yet most research on sovereign borrowing in emerging markets still focuses on debt stocks: how much governments owe, in what currency, and to whom (Bolton et al. 2023). Debt stocks matter, but they are the cumulative outcome of many individual issuance decisions about when to borrow, how much, at what maturity, and in which currency. These are the choices debt managers make, and they are much harder to study because the underlying issuance data remain limited (Presbitero et al. 2016).
In this column, we shift attention from debt stocks to debt issuance. Using a novel auction-level dataset covering more than 75,000 sovereign bond issuance events across 20 emerging market economies, we show that local-currency and foreign-currency issuance follow fundamentally different logics. Local-currency issuance is mostly driven by refinancing needs, as maturing debt often has to be rolled over. Foreign-currency issuance is more strategic, responding to global financial conditions, investor sentiment, and terms-of-trade shocks. Looking at issuance at the auction level also helps uncover a feature that standard bond databases often miss: governments frequently reopen existing bonds rather than issue entirely new ones, so the remaining tenor at the time of issuance matters more than original maturity for understanding how debt portfolios are actually managed.
A new auction-level dataset
To study these issuance decisions directly, in Wong et al. (2026) we assemble a comprehensive issuance event-level dataset that merges official national publications with commercial databases. The dataset covers 20 emerging market economies across Asia, Emerging Europe, the Middle East, Africa, and Latin America over the period 2000–2023. It comprises over 75,000 issuance events – including more than 20,000 inaugural issues and 55,000 reopenings – and captures detailed information on coupon structure, maturity, amounts issued, auction yields, and prices.
Total bond issuance on a flow basis grew from roughly $500 billion in 2000 to nearly $3.5 trillion by 2023. China accounts for a rapidly increasing share: less than 10% of the sample total in 2005, but more than 45% by 2023 (Figure 1). Other large issuers include Egypt ($456 billion in 2023), India ($366 billion), Brazil ($265 billion), and Mexico ($223 billion).
Figure 1 Total government bond issuance
Notes: This figure plots the evolution of total government bond issuance (in billion US dollars) over the period 2000-2023. The orange bars show Chinese central government bond issuance and the blue bars show central government bond issuance by the other 19 countries in our dataset.
The majority of issuance is in local currency and has a maturity at issuance of five years or less, though this varies considerably by region. Asian emerging markets rarely issue in foreign currency, and about half of their local-currency issuance is long-term. In Emerging Europe and Africa, by contrast, most local-currency debt has short initial maturities. Foreign-currency bonds, which ranged between 20% and 30% of total issuance in the early 2000s, fell below 10% around 2006–2008 before recovering to 20–30% after the Global Crisis (Figure 2).
Figure 2 Composition of bond issuance
Notes: This figure illustrates the evolution of the composition of central government bond issuance. The top left panel includes all bonds, the top right shows only foreign currency bonds, and the bottom left focuses on local currency bonds. The six panels in the bottom right corner present the same information disaggregated by region. Light orange bars indicate the share of foreign currency bonds with a maturity of less than five years; dark orange bars represent long-term foreign currency bonds; dark blue bars show medium-term local currency bonds; and light blue bars reflect long-term local currency bonds
Local-currency issuance is driven by refinancing needs
In any given year, a treasury must finance the budget deficit and roll over maturing debt by issuing new bonds, adjusting its stock of bank loans, or drawing down cash reserves. We estimate how bond issuance responds to these financing needs, distinguishing between local-currency (LC) and foreign-currency (FX) instruments.
For local-currency bonds, issuance tracks refinancing needs very closely. The model fits tightly, with an R-squared of 0.95. Maturing foreign-currency debt, by contrast, has essentially no effect on local-currency issuance. The budget balance has a negative but modest association with local-currency issuance volumes, consistent with deficits being temporarily financed through non-bonded debt and cash management.
When we decompose issuance further by maturity, we find that, on average, longer-term local-currency bond issuance responds not only to maturing bonds of the same type but also to maturing bills, consistent with a gradual lengthening of the local-currency debt portfolio.
The strategic nature of foreign-currency issuance
The picture for foreign-currency bonds is strikingly different. While maturing foreign-currency debt does predict new foreign-currency issuance, the relationship is weaker and the overall model fit is weaker. This suggests that foreign-currency issuance is not primarily about rolling over existing obligations but reflects more strategic considerations.
Several patterns support this interpretation. Countries with higher foreign investor participation in their domestic bond markets issue less in foreign currency, suggesting that the ability to attract international capital into local-currency markets reduces the need to borrow abroad. Higher US interest rates and increased global uncertainty (proxied by the VIX) are both associated with lower foreign-currency bond issuance, consistent with the idea that emerging market issuers pull back from international markets when financial conditions tighten.
The maturity structure of foreign-currency bonds also responds to terms-of-trade shocks. When commodity import prices rise, an adverse shock for many emerging markets, foreign-currency maturities shorten, precisely when rollover risks are most elevated. Rising export commodity prices, conversely, are associated with longer foreign-currency tenors.
Using quarterly data and a specification that interacts a foreign-currency dummy with measures of global conditions – the Global Financial Cycle index of Miranda-Agrippino and Rey (2020), the VIX, and expected US ten-year Treasury yields – we find a consistent pattern: favourable global conditions are associated with relatively more foreign-currency bond issuance. A one standard deviation improvement in global financial conditions is associated with an increase of about 0.6 percentage points of GDP in foreign-currency issuance, or roughly one-sixth of the average difference in issuance volumes between currencies when global conditions are at their mean.
When we decompose this effect, the results suggest that local-currency issuance decreases during good times while foreign-currency issuance remains roughly constant. In other words, favourable global conditions increase the foreign-currency share of issuance, but emerging markets do not appear to go on a borrowing spree. The shift is compositional rather than expansionary. The motivation to tap foreign markets during favourable conditions appears to dominate the potential effect of increased foreign investor participation in local-currency markets.
Policy implications
Our findings have several implications for debt management.
First, they underscore the importance of developing deep domestic bond markets as core infrastructure for macroeconomic resilience. Local-currency borrowing can be backstopped by the domestic central bank, eliminates currency-induced balance-sheet risk, and provides greater room for countercyclical fiscal policy (Eichengreen et al. 2023, Onen et al. 2025). The strong mechanical relationship between maturing local-currency debt and new issuance confirms that these markets function as reliable funding infrastructure.
Second, foreign-currency borrowing can serve a useful tactical purpose – allowing governments to lock in favourable terms during periods of low spreads and high risk appetite – but debt strategies should not presume permanent access to international markets. Medium-term plans need to incorporate contingency planning for sudden stops. Commodity exporters face particular vulnerabilities, as adverse terms-of-trade shocks are associated with shorter foreign-currency maturities, reinforcing the importance of using commodity windfalls to lengthen maturities and build liquidity buffers.
Third, our work highlights persistent gaps in public reporting of sovereign debt. Substantial inconsistencies remain in how countries disclose issuance details. Governments should prioritise publishing standardised, high-frequency data on debt composition, broken down by currency, maturity, and holder type, alongside clear refinancing calendars (Manger et al. 2025). International organisations can play a pivotal role by promoting harmonised reporting standards, enabling more rigorous evaluations of debt sustainability.

Executive Summary
Multi-agent AI systems extend beyond single-agent architectures by enabling groups of specialized agents to collaborate on complex tasks. This approach improves functionality and scalability, but it also expands the attack surface, introducing new pathways for exploitation through inter-agent communication and orchestration.
This research examines Amazon Bedrock Agents’ multi-agent collaboration capabilities from a red-team perspective. We demonstrate how under certain conditions an adversary could systematically progress through an attack chain:
Determining an application’s operating mode (Supervisor or Supervisor with Routing)
Discovering collaborator agents
Delivering attacker-controlled payloads
Executing malicious actions
The resulting exploits included disclosing agent instructions and tool schemas and invoking tools with attacker-supplied inputs.
Importantly, we did not identify any vulnerabilities in Amazon Bedrock itself. Moreover, enabling Bedrock’s built-in prompt attack Guardrail stopped these attacks. Nevertheless, our findings reiterate a broader challenge across systems that rely on large language models (LLMs): the risk of prompt injection. Because LLMs cannot reliably differentiate between developer-defined instructions and adversarial user input, any agent that processes untrusted text remains potentially vulnerable.
We performed all experiments on Bedrock Agents the authors owned and operated, in their own AWS accounts. We restricted testing to agent logic and application integrations.
We collaborated with Amazon’s security team and confirmed that Bedrock’s pre-processing stages and Guardrails effectively block the demonstrated attacks when properly configured.

Introduction to Bedrock Agents Multi-Agent Collaboration
Amazon Bedrock Agents is a managed service for building autonomous agents that can orchestrate interactions across foundation models, external data sources, APIs and user conversations. Agents can be extended with additional capabilities such as:
Action groups, which define the tool and API calls they are permitted to make
Knowledge bases, which enable retrieval-augmented generation
Memory, which preserves contextual state across sessions
Code interpretation, which allows agents to dynamically generate and execute code
The multi-agent collaboration feature enables several specialized agents to work together to solve complex and multi-step problems. This approach makes it possible to compose modular agent teams that divide responsibilities, execute subtasks in parallel and combine specialized skills for greater efficiency.
Bedrock supports two collaboration patterns for this orchestration:
Supervisor Mode
Supervisor with Routing Mode
Workflow in Supervisor Mode
In Supervisor Mode, the supervisor agent coordinates the entire task from start to finish. It analyzes the user’s request, decomposes it into sub-tasks and delegates them to collaborator agents.
Once the collaborators return the responses, the supervisor consolidates their results and determines whether additional steps are required. By retaining the full reasoning chain, this mode ensures coherent orchestration and richer conversational context.
As illustrated in Figure 1, Supervisor Mode is best suited for complex tasks that require multiple interactions across agents, where preserving detailed reasoning and context is critical.
Figure 1. Data flow in Supervisor Mode
Workflow in Supervisor With Routing Mode
Supervisor with Routing Mode adds efficiency by introducing a lightweight router that evaluates each request before deciding how it should be handled. When a request is simple and well-scoped, the router forwards it directly to the appropriate collaborator agent, which then responds to the user without involving the supervisor. When a request is complex or ambiguous, the router escalates it to Supervisor Mode so full orchestration can occur.
As shown in Figure 2, the blue path depicts direct routing for simple tasks, while the orange path illustrates escalation to the supervisor for more complex ones. This hybrid approach reduces latency for straightforward queries while preserving orchestration capabilities for multi-step reasoning.
Figure 2. Data flows in the Supervisor with Routing Mode.
Red-Teaming Multi-Agent Application
This section describes our methodology for red-teaming multi-agent applications. The goal is to deliver attacker-controlled payloads to arbitrary agents or their tools. Depending on the functionalities exposed, successful payload execution may result in sensitive data disclosure, manipulation of information or unauthorized code execution.
To systematize this process, we designed a four-stage methodology that leverages Bedrock Agents’ orchestration and inter-agent communication mechanisms:
Operating mode detection: Determine whether the application is running in Supervisor Mode or Supervisor with Routing Mode
Collaborator agent discovery: Discover all collaborator agents and their roles in the application
Payload delivery: Deliver attacker-controlled payloads to target agents or their integrated tools
Target agent exploitation: Trigger the payloads and observe execution on the target agents
AWS suggested using Bedrock’s built-in prompt attack Guardrail feature. We confirmed that it could effectively stop all the attacks.
Environment Settings
Demo Application
To evaluate the methodology, we used the publicly available AWS workshop sample, Energy-Efficiency Management System. This demo application includes one supervisor agent and three collaborators responsible for energy consumption forecasting, solar panel advisory and peak load optimization. It serves as an educational example designed to showcase the orchestration capabilities of Amazon Bedrock Agents.
We conducted the demonstrated attacks in this section under the following assumptions:
The attacker was a legitimate user with access to the application’s chatbot interface
All agents were powered by the Amazon Nova Premier v1 foundation model
The application used the default prompt templates without customization
Bedrock Guardrails and pre-processing stages were not enabled during testing
Operating Mode Detection
The operating mode of a multi-agent application — either Supervisor Mode or Supervisor with Routing Mode — dictates how user requests are delegated to collaborator agents. To reliably deliver a payload to a target agent, it is necessary to determine the operating mode.
We designed a detection technique that relies on observing the system’s response to a crafted detection payload. By analyzing how the request is disseminated — whether it is handled by the supervisor alone or intercepted by a router — we can infer the application’s operating mode.
Figure 3 illustrates how the detection payload is constructed, while Figure 4 shows how its output appears in the chatbot interface. The color coding in the figures corresponds to the explanation below the images.
In applications running in Supervisor with Routing Mode, the detection payload is designed to bypass the supervisor and reach a collaborator agent. The technique involves:
Using the tag in the router’s prompt template to determine whether the request is being processed by a router
Explicitly asking the router to forward the request to the first collaborator agent listed in
Instructing that collaborator agent to return a special message, confirming that routing occurred
In applications running in Supervisor Mode, the detection payload ensures the request is handled by the supervisor only. The technique involves:
Using the AgentCommunication__sendMessage() tool in the supervisor’s prompt template to determine whether the request is being processed by the supervisor
Instructing the supervisor to respond to the end user with a special message by invoking the AgentCommunication__sendMessage() tool
In summary, the tag serves as a marker of router-based handling, while the AgentCommunication__sendMessage() tool signals supervisor-only processing. These artifacts allow us to reliably distinguish between Supervisor Mode and Supervisor with Routing Mode.
Complete router and supervisor prompt templates are provided in the Additional Resources section.
Collaborator Agent Discovery
To fully explore a multi-agent application’s capabilities, we must first identify all collaborator agents. This stage involves sending a discovery payload designed to query the supervisor about available collaborators. Crucially, the payload must reach the supervisor in both operating modes:
In Supervisor Mode, all requests are routed through the supervisor, so the supervisor is guaranteed to process the identification payload
In Supervisor with Routing Mode, the payload must appear sufficiently complex or ambiguous to force the router to escalate it to the supervisor rather than forwarding it to a collaborator
Our discovery payload, illustrated in Figure 5, was designed to meet these conditions by falling outside the scope of any single collaborator’s capabilities. As a result, it consistently reaches the supervisor regardless of the operating mode, ensuring that a single payload is sufficient for collaborator discovery across both modes.
Figure 5. Collaborator agent discovery payload.
The design of this payload was guided by an analysis of the supervisor’s prompt template (Figure 6). The template explicitly defines accessible collaborators within the tag. Ideally, extracting the contents of this tag would directly reveal agent names and descriptions. However, guardrails embedded in the template block such direct disclosure. These guardrails instruct the supervisor not to expose information about tools or agents (highlighted in pink in Figure 6).
Figure 6. Supervisor prompt template snippet.
To bypass these restrictions, the payload applies a social engineering technique that indirectly prompts the supervisor to describe each collaborator’s functionality in general terms rather than revealing raw prompt contents. Figure 7 shows an example interaction. While the responses do not disclose exact agent names or identifiers, they provide enough information to infer each agent’s purpose.
Figure 7. Send collaborator agent discovery payload to the application’s chatbot user interface.
Payload Delivery
The payload delivery stage focuses on sending attacker-controlled instructions to specific collaborator agents. Since delivery paths differ between operating modes, we designed tailored payload templates for each mode, with the objective of ensuring that payloads reach the target agent unaltered.
Payload Delivery in Supervisor Mode
In Supervisor Mode, the supervisor analyzes every request and decides whether to delegate it to a collaborator. To ensure the payload is delivered to the intended agent, the request must signal unambiguously which collaborator should handle it. Our payload template (Figure 8) achieves this by:
Referencing the target agent using information obtained during the collaborator discovery stage
Leveraging the supervisor’s AgentCommunication__sendMessage() tool to send the exact payload to the target agent
Explicitly instructing the supervisor not to modify the payload, ensuring the collaborator receives the attacker-controlled instructions as-is
Figure 8. Payload delivery template for sending instructions to a target agent in Supervisor Mode.
Payload Delivery in Supervisor With Routing Mode
In Supervisor with Routing Mode, the router forwards requests directly to collaborators whose capabilities most closely match the request. To reliably deliver a payload, the request must convince the router that it falls within the target agent’s domain. The payload delivery template (Figure 9) achieves this by embedding clear references to the target agent. It does so by using information obtained during the collaborator discovery stage again, so that the router consistently forwards the request to the target agent.
Figure 9. Template for delivering instructions to a target agent in the Routing Mode.
Target Agent Exploitation
Once attacker-controlled payloads are successfully delivered to a target agent, the final step is to trigger their execution. Depending on the payload’s intent, exploitation may lead to outcomes like information leakage, unauthorized data access or misuse of integrated tools. To illustrate this stage, this section demonstrates three end-to-end attacks each executed under a specific operating mode.
Instruction Extraction
This attack aims to extract an agent’s system instructions, internal logic or proprietary configuration details. Disclosure of such information can reveal sensitive implementation details and aid in further attacks.
Figure 10. Instruction extraction payload.
The instruction extraction payload shown in Figure 10 leverages social engineering to indirectly solicit the target agent’s instructions while bypassing the guardrails that prevent explicit prompt disclosure.
As Figure 11 shows, when the payload targets the Solar Panel Management agent in Supervisor Mode, the agent responds with paraphrased descriptions of its capabilities and configurations. Although the exact system prompt remains hidden, the returned information is sufficient to infer the agent’s role, capabilities and operational rules.
Figure 11. An example of instruction extraction in Supervisor Mode.
Tool Schema Extraction
This attack is a variant of instruction extraction attack that aims to extract an agent’s tools and their schemas. Gaining this information allows attackers to understand the actions the agent can perform, the conditions that trigger the actions and the presence of any hidden or undocumented tools.
The tool schema extraction payload (Figure 12) closely resembles the instruction extraction payload but is adapted to elicit information about tool schemas.
Figure 12. Tool schema extraction payload.
In Figure 13, the payload is executed against the Peak Load Optimization agent in Supervisor with Routing Mode. The agent responds with detailed tool information, including:
Each tool’s purpose
Required input parameters
Expected outputs
Figure 13. An example of tool schema extraction in Supervisor with Routing Mode.
Tool Invocation with Malicious Inputs
This attack attempts to invoke a target agent’s tool using attacker-controlled inputs. If successful, attackers may misuse tools for unintended purposes or exploit vulnerabilities within the tools.
Figure 14 shows a crafted payload that instructs the Solar Panel Management agent to invoke its “create a ticket” tool. Normally, this tool should be restricted to solar panel issues that cannot be resolved automatically. However, as shown in Figure 15, the payload successfully persuades the agent (running in Supervisor Mode) into creating a fraudulent ticket that issues a refund and credits to the attacker. The agent’s tool invocation log confirms that the call was executed with the exact attacker-supplied content, demonstrating a compromise of intended tool logic.
Figure 14. Tool misuse payload.Figure 15. An example of tool misuse in Supervisor Mode. The right figure is the agent’s tool invocation log.
The three target agent exploitation examples demonstrate how exploitation can progress in stages:
Starting with disclosure of internal logic
Escalating to enumeration of tool schemas
Resulting in direct tool misuse through malicious inputs
This progression highlights how even limited information leakage can serve as a foundation for more impactful compromises in multi-agent applications.
General Defenses and Mitigations
Securing multi-agent applications in Amazon Bedrock requires a layered defense strategy that combines Bedrock’s built-in security features with general best practices for secure agent design.
Bedrock Security Features
Pre-processing prompt The pre-processing prompt gives developers control over how user inputs are interpreted before they enter the orchestration pipeline. It enables early-stage validation and classification of requests. While Bedrock provides a default version, this prompt can be customized to detect suspicious patterns and enforce application-specific constraints. Positioned at the front of the workflow, it acts as the first line of defense against malformed or adversarial inputs.
Bedrock guardrails Guardrails provide runtime content filtering and policy enforcement for both inputs and outputs. They support prompt injection detection, PII redaction, response grounding and topic restriction. In multi-agent setups, guardrails can be tailored per agent depending on role and sensitivity — for instance, a data-processing agent might emphasize privacy protections, while a code-generation agent prioritizes injection defense. Because guardrails operate independently of prompt templates, they serve as a centralized mitigation layer that complements application logic.
General Agent Security Best Practices
Agent capability scoping Assign each agent a narrowly defined task and reinforce it in the prompt template so that unrelated requests are rejected. Specialization reduces reasoning scope, prevents inappropriate tool use and minimizes the overall attack surface.
Tool input sanitization Validate inputs at both the prompt and tool levels. Prompt should define acceptable input formats, while tool implementations must enforce strict checks using schemas, type validation or allowlists. This dual-layer validation prevents malformed or malicious inputs from propagating.
Tool vulnerability scanning Since agents frequently invoke APIs, services or code execution environments, these tools must be treated as part of the attack surface. They should undergo regular security testing, including Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST) and Software Composition Analysis (SCA). Integrating these practices into the development lifecycle helps identify vulnerabilities early and reduces the risk of downstream exploitation.
Principle of least privilege Configure agents and tools to operate with the minimum privileges necessary. Limit agents to only the tools essential to their role and restrict tools to minimal data and API permissions. Where possible, sandbox execution to contain misuse or compromise. Enforcing least privilege principles reduces lateral movement and limits the impact of successful attacks.
Conclusion
As multi-agent systems gain adoption in real-world AI applications, their growing complexity introduces new security risks. This study demonstrated how adversaries may attack unprotected Amazon Bedrock Agents applications by chaining together reconnaissance, payload delivery and exploitation techniques that exploit prompt templates and inter-agent communication protocols.
Our findings highlight the broader challenge of securing agentic systems built on LLMs:
Mitigating prompt injection
Preventing tool misuse
Controlling unintended task delegation
The good news, as AWS notes, is that the specific attack we demonstrated can be mitigated by enabling Bedrock Agent’s built-in protections — namely the default pre-processing prompt and the Bedrock Guardrail — against prompt attacks.
Defending against these threats requires a layered approach. Scoping agent capabilities narrowly, validating tool inputs rigorously, scanning tool implementations for vulnerabilities and enforcing least-privilege permissions all reduce the attack surface. Combined with Bedrock’s security features, these practices enable developers to build more resilient multi-agent applications.
As agent-based systems continue to evolve, security-by-design must remain a central principle. Anticipating adversarial use cases and embedding defenses throughout the orchestration pipeline will be key to ensuring that multi-agent applications operate safely, reliably and at scale.

WASHINGTON—April 3, 2026—The Semiconductor Industry Association (SIA) today announced global semiconductor sales were $88.8 billion during the month of February 2026, an increase of 7.6% compared to the January 2026 total of $82.5 billion and 61.8% more than the February 2025 total of $54.9 billion. Monthly sales are compiled by the World Semiconductor Trade Statistics (WSTS) organization and represent a three-month moving average. SIA represents 99% of the U.S. semiconductor industry by revenue and nearly two-thirds of non-U.S. chip firms.
“Global chip sales remained very strong in February, exceeding January’s totals and far outpacing sales from February of last year,” said John Neuffer, SIA president and CEO. “Sales into the Asia-Pacific region, the Americas, and China were all major drivers of year-to-year growth. Strong global demand is expected to persist during the remainder of the year, with annual sales projected to reach roughly $1 trillion globally.”
Regionally, year-to-year sales in February were up in Asia Pacific/All Other (93.5%), the Americas (59.2%), China (57.4%), and Europe (42.3%), but declined in Japan (-0.3%). Month-to-month sales in January increased in the Americas (12.6%), Europe (10.2%), Asia Pacific/All Other (6.0%), China (3.6%), and Japan (3.0%).

Taking a quick look at the top challenges by firm size, the mix of growth bottlenecks is quite different depending on size.
Micro firms (1–4 employees): Compliance and capacity bottlenecks
For micro firms, the top-ranked challenge is regulatory complexity, followed closely by capacity constraints (getting work done on time with limited staff). These firms often lack the infrastructure to scale efficiently, making compliance a growth bottleneck.
Implication: Automating routine tasks and leveraging cloud platforms can free up capacity and reduce risk.
Small firms (5–19 employees): Growth without burnout
Small firms rank client expectations and talent retention as their biggest hurdles. They’re growing, but may be missing the systems or staffing needed to maintain service quality. Burnout risk is real, and operational strain shows up in missed opportunities for advisory work.
Implication: Invest in workflow automation and structured client engagement to balance growth with quality.
Mid-sized firms (20–49 employees): Scaling vs. specialization
Mid-sized firms face a more complex mix: economic uncertainty, client demands, and training needs compete for attention. These firms may be large enough to feel macroeconomic pressures but not always agile enough to pivot quickly.
Implication: Strategic planning and targeted tech adoption – especially AI for forecasting and analytics – can help mid-sized firms navigate uncertainty and scale sustainably.
Large firms (50+ employees): Complexity at scale
Technology adoption and integration are top concerns for large firms. These firms aren’t debating whether to adopt tech; they’re wrestling with how to integrate advanced tools across sprawling operations. Talent enablement is another critical concern, as staff demand advanced tech skills and flexible work models.
Implication: Treat tech integration as a strategic initiative, not a back-office project. Pair it with robust training programs to ensure adoption sticks.
The bigger story
These challenges are interconnected, not isolated. Regulatory complexity encourages tech adoption; tech adoption enhances talent enablement; talent enablement improves client experience. Firms that respond with integrated strategies – linking technology, talent, and client engagement – will transform these challenges into opportunities for growth.
