Mumbai, Jun 7 (IANS): The Indian central bank's decision to hike repo rate by 25 basis points on Wednesday has boosted investors' sentiments leading the key Indian equity indices surge during afternoon session trading on Thursday.

Following a cycle of rate cuts begun in January 2015, the RBI on Wednesday raised its key interest rate for the first time by 25 basis points to 6.25 per cent.

"Indian equity markets opened in positive mood and are trading higher after the Monetary Policy Committee hiked repo rates by 25 bps to 6.25%, for the first time in four years, while maintaining a neutral stance," said Dhruv Desai, Director and Chief Operating Officer at Tradebulls.

"The reverse repo rate under the liquidity adjustment facility (LAF) stands adjusted to 6 per cent and the marginal standing facility (MSF) rate and the Bank Rate to 6.50 per cent," the RBI said.

"The decision of the Monetary Policy Committee (MPC) is consistent with the neutral stance of monetary policy in consonance with the objective of achieving the medium-term target for consumer price index (CPI) inflation of 4 per cent within a band of +/- 2 per cent," it added.
