The benchmark 10-year government bond yield remained unchanged from last week's close at 7.21 per cent. After a brief decline earlier in the week, Indian government bond yields surged yesterday and ended the week at the same five-month high recorded last week. The surge in U.S. yields, driven by bearish investor sentiment about rate cuts, was the main factor in the increase in bond yields. Another factor was the expectation of a new domestic debt supply.
