The Reserve Bank of India (RBI) hiked the interest rates on Tuesday for a fourth time this year in a fresh bid to tame double-digit inflation.

India’s inflation rate is now the highest among the G-20 economic powers.

The central bank lifted the repo rate by 25 basis points (bps) to 5.75%, in line with expectations, but raised the reverse repo rate by 50 bps to 4.50%.

The reverse repo is the rate at which the central bank absorbs liquidity against government securities while the repo is the rate at which it provides money to banks.
