    OpenAI’s chatbot is down for some users

    OpenAI’s artificial intelligence chatbot ChatGPT is down for some users.

    The company said it is “currently experiencing issues,” including “increased ChatGPT error rates,” according to an update on OpenAI’s status page.

    “We have applied the mitigation and are monitoring the recovery,” the status page said.

    OpenAI did not immediately respond to a request for comment.

    Roughly 3,000 people reported issues with the chatbot on Tuesday, according to Downdetector, a website that tracks outages.

    The outage comes days after OpenAI disclosed a security breach at Mixpanel one of OpenAI’s data analytics providers.

    The breach compromised user information, such as names, emails and other details tied to the OpenAI API.

    OpenAI did not disclose how many users were affected, saying in a blog post that an attacker “exported a dataset containing limited customer identifiable information and analytics information.”

    OpenAI kickstarted the AI boom with the launch of ChatGPT three years ago. As of October, OpenAI said more than 800 million people use the chatbot each week.

    Stocks rose on Tuesday, boosted by gains in bitcoin and technology names, as traders recovered some of the ground lost in the previous session.

    The Dow Jones Industrial Average gained 185.13 points, or 0.39%, to end the day at 47,474.46. The S&P 500 climbed 0.25% to settle at 6,829.37, while the Nasdaq Composite advanced 0.59% to finish at 23,413.67.

    Bitcoin rose around 7% Tuesday, recouping some of its losses from the prior day. Tech players linked to the artificial intelligence trade supported the broader market as well. AI chip darling Nvidia increased almost 1%, while AI infrastructure play Credo Technology soared 12% and hit an all-time high on the back of better-than-expected earnings.

    To be sure, it’s been a topsy-turvy session for stocks. The S&P 500 and Dow briefly turned negative on the day, while the Nasdaq got close to the flatline before moving back higher.

    The major U.S. indexes began the week in the red, ending five-day win streaks on Monday. Risk-off sentiment has pressured the bull market in recent weeks as worries of persistent inflation, elevated valuations and returns on artificial intelligence spending weigh on investors.

    Although November was a mixed month for stocks, investors are watching for catalysts that could lead to a year-end rally.

    Traders are currently optimistic that the Federal Reserve will announce an interest rate cut on Dec. 10 at conclusion of its next policy meeting. Markets are pricing a roughly 89% chance of a cut during the upcoming meeting, which is much higher than the odds from mid-November, according to the CME FedWatch tool.

    “Markets appear to have moved away from uncertainties surrounding Fed policy and the Dec. 10 FOMC and focusing instead on better-than-expected earnings projections for the fourth quarter and calendar year 2026, in addition to looking beyond the economic soft patch we’re currently experiencing to growth accelerating later next year,” said Doug Beath, global equity strategist at Wells Fargo Investment Institute. “Seasonality also favors stocks in December, particularly after a weak November.”

    According to the Stock Trader’s Almanac, the S&P 500 averages a gain of more than 1% in December, making it the third-best month of the year for the benchmark in records going back to 1950.

  • iFlow | Short Thoughts | December FOMC probably too early for balance sheet expansion

    iFlow | Short Thoughts | December FOMC probably too early for balance sheet expansion

    The Fed’s standing repo facility (SRF) was tapped for $26bn over the course of the day on December 1, making it the largest daily uptake since $50bn in usage on October 31. Also on December 1, the tri-party general collateral repo rate (TGCR) rose to 18bp over the interest paid on reserves at the Fed (IORB). Both developments speak to tightening in funding markets heading into year end. The current situation is hardly a surprise, as we have commented on recently (see here and here).

    However, on November 28, the effective federal funds rate moved up a basis point, from 4.88% to 4.89% with TGCR-IORB spreads at 18bp. This illustrates the Fed’s discomfort with such upward pressure on repo spreads. Tight liquidity conditions in the funding markets can ultimately lead to upward pressure on the Fed’s operating target, threatening rate control.

    While funding pressure has materialized around specific dates (month- and quarter-ends, settlement days, tax dates), there is the risk it will happen more frequently, including on otherwise uneventful days. This is why the Fed has indicated it will eventually need to resume increasing its balance sheet. As other balance sheet liabilities increase (namely, currency in circulation), reserves will fall, exacerbating tight liquidity conditions in the funding markets. Reserves are currently reckoned to be no longer abundant, but merely ample. Reserve management operations will eventually feature in the Fed’s toolkit, although pinpointing when they might commence is difficult.

    Exhibit #1 shows the daily usage of the SRF over the past half year and illustrates how its usage increases when funding is stressed. It’s worth noting that the Fed would probably prefer to see the SRF used more frequently and in larger sizes than it currently is, reducing the eventual need for open market operations. Moving to the latter presents a potential communications problem for the Fed, which would have to make it clear that such operations are not a return of quantitative easing, but are indeed reserve management policies. The SRF’s attractiveness suffers due to both internal and executive stigma, as well as a lack of central clearing.

    We wrote about the Fed’s upcoming monetary policy decision last week and will write a formal preview of the FOMC next week. However, it’s worth asking here whether the Fed would announce reserve management operations at next week’s gathering. We think it’s unlikely to occur so soon. For one thing, there have so far been only vague references to such market operations in the Fed’s public communications. We would have expected more specific guidance if they were to commence soon.  Furthermore, with funding market strains still mostly limited to specific dates, it could be a bit premature to set up such operations. Nevertheless, we expect them to begin early in 2026, as funding markets gradually tighten further.
