As inflation trends upwards, the Reserve Bank of India may keep interest rate unchanged in the upcoming monetary policy review on Tuesday and possibly take a call post-budget 2016-17, which will give a direction about key macroeconomic parameters, including fiscal deficit, PTI quoted experts as saying. However, some experts also feel that there is a case for front-loading of interest rate cut to give a push to economy. According to a Citigroup report, RBI is likely to keep key policy rates unchanged until the budget and go for a 0.25% easing in March or April this year.
