The Royal Bank of Scotland today said the economic indicators like softening of inflation suggests that key interest rates could be slashed sooner than later by the Reserve Bank of India. Reserve Bank had kept the key interest rates unchanged while unveiling its fourth bi-monthly monetary policy statement for 2014-15 on September 30. "I think the RBI is a very fine institution and it is their job to take a call on monetary policy, rate cut and inflation...but the indicators seem to suggest that rate cut would be sooner rather than later," the RBS's Country Executive Brijesh Mehra told reporters. According to him, one can argue that easing of inflation and less capital expenditure do indicate scope of interest rate cut by Reserve Bank of India. The inflation measured in terms of Wholesale Price Index (WPI) touched a five year low of 2.38 per cent in September. Besides, retail inflation has also dropped to 6.46 percent, the lowest since the new series of Consumer Price Index was released in January 2012. The experts think that the slight tinkering in the key interest rate by RBI in its next bimonthly policy statement scheduled on December 2 will help in perking up economic growth as well as lowering the burden of home and other loan instalments.
