Mumbai: The yield on 10-year government bond jumped Monday to 6.57%, highest level in nearly a month, on higher supply of this tenor in the Centre’s borrowing for the fiscal second-half. Caution ahead of MPC’s decision on Wednesday also weighed. The bonds closed at 6.55% as compared to 6.52% on Friday. In the total borrowing of ₹6.77 lakh crore in H2, supply of 10-year bonds has increased the most by 220 basis points to 28.4% in the second half, while those of ultra long bonds (30 years and above) has been cut by 550 bps to 29.5%. Bond dealers, however, said the calendar is overall positive for the market, which is currently grappling with lower demand for long bonds.
