The RBI had conducted two OMOs for a total of Rs 25,000 crore in May

India's benchmark 10-year bond yield dropped to its lowest level in more than a year on Monday buoyed by a fall in global crude oil prices and announcement of another round of open market operations by the central bank.

"There is also possibly some foreign portfolio investor buying happening in the market," a senior trader at a private bank said.

The benchmark 10-year bond yield at 7.16 per cent, its lowest level since April 9, 2018. It had ended at 7.23 per cent on Friday.

Traders expect sentiment for bonds to remain positive ahead of the upcoming monetary policy committee meeting outcome on June 6. The Reserve Bank of India (RBI) last week announced an open market operation to buy up to Rs 15,000 crore ($2.16 billion) worth of bonds on June 13.

"The auction amount overall is lesser than what they did in May but they have not said they won't do more. So we need to wait and watch. They will conduct another round possibly if they see the need for it," a senior dealer with a state-run bank said.

The RBI had conducted two OMOs for a total of Rs 25,000 crore in May.
