Days before Reserve Bank Governor Raghuram Rajan unveils his bi-monthly monetary policy, Finance Minister Arun Jaitley today asserted that common sense says the interest rates should come down. Jaitley said inflation is very much under control and the country is better prepared than most emerging economies to weather the global economic turbulence. Common sense says the rates should come down he told The Financial Times.RBI is scheduled to present its fourth bi-monthly monetary policy of the current fiscal on September 29 amid clamour by the government and the industry for an interest rate cut to bring down cost of capital and boost growth. Jaitley said if interest rates were lowered, the economy could grow faster than 7-7.5 per cent. This year since January, RBI cut interest rates by a total of 0.75 per cent in three tranches but refrained from taking any action at the last monetary policy review in August.
