Indian government bonds fell early on Friday, giving up part of the week's gains, as higher oil prices weighed on sentiment ahead of New Delhi's hefty debt sale. Higher crude prices also pushed the U.S. 10-year Treasury yield up 7 basis points overnight and in Asian trade to 4.68%, reducing the appeal of riskier emerging market debt. The benchmark 6.94% 2036 bond yielded 6.7869% at 10:40 a.m. IST, 2 basis points above Thursday's close. It was still set for its first weekly decline in five weeks.
