MUMBAI: Federalbond yields eased on Monday on expectations of demand from foreign investors after the market regulator announced an auction for the remaining unsold limit of long-term government bonds.
However, higher oil prices averted a bigger drop in yields. At 11:11 a.m. (05410 GMT), the 10-year benchmark bond yield was down 5 basis points on the day at 8.40 percent after easing to 8.39 percent.
Volumes were a moderate 55.60 billion rupees ($1.3 billion) on the central bank's trading platform.
The one-year overnight indexed swap rate was down 1 basis point at 8.28 percent while the benchmark five-year rate was down 5 basis points at 7.45 percent.
"The main reason for the drop in yields is the debt limit auction for foreign institutional investors, but oil is high," said a senior trader at a state-run bank.
Late last Friday, India's stock market regulator said it would auction the unutilised limit in long-term government bonds to foreign institutional investors on Aug. 5.
