RBI kept its benchmark Bank Rate unchanged but hiked Repo Rate to 6.25 per cent and Reverse Repo Rate to 5.25 per cent to keep inflation under check.

Pointing to high global oil prices that have led to a rise in inflation not only in India but across the world, Chidambaram said: "To contain the upside risk to price stability, strong vigil is being maintained by both the government and RBI."

Enthused by the hike in GDP growth forecast by RBI from 7 to 7-7.5 per cent for 2005-06, Chidambaram said agriculture was likely to perform well and business confidence index was at the highest level in last 10 years.

"There are indications of an investment boom supported by buoyant growth in credit as well as in equity finance. It is critical to maintain this investment momentum to accelerate growth further," he told reporters.
