The Reserve Bank of India (RBI) on Wednesday hiked its key interest rate (repo rate) by 50 basis points (bps), in a bid to tame rising inflation. The repo rate – the rate at which the RBI lends to commercial banks – now stands at 4.9 per cent. The decision taken unanimously by the RBI Governor Shaktikanta Das-led Monetary Policy Committee (MPC) is aimed at reigning in inflation that has remained stubbornly above the central bank’s tolerance limit for the past several months.
