The Reserve Bank on Friday raised the key interest rate -- the third straight increase since May -- in an effort to cool stubbornly high inflation and defend the rupee.
The repurchase rate was raised by 50 basis points to lift the interest rate to the pre-pandemic level. The 5.40 per cent repo rate was last seen in August 2019.

Forex traders said foreign fund inflows into capital markets and softening crude oil prices boosted the local currency.
Foreign institutional investors remained net buyers in the capital market on Thursday as they purchased shares worth Rs 1,474.77 crore, as per exchange data.

Reserve Bank of India (RBI) Governor Shaktikanta Das said the RBI will remain watchful and maintain the stability of the rupee.
"The depreciation of the Indian rupee is more on account of the appreciation of the US dollar rather than weakness in macroeconomic fundamentals of the Indian economy. Market interventions by the RBI have helped in containing volatility and ensuring the orderly movement of the rupee," he said.
