The next major event before the Policy meet by RBI on the 1st April is the WPI which is due to come out at noon today.The WPI may follow the CPI way and come down, food inflation should be down i any case and we need to wait and see if the core WPI softens. This is the key to the whole Index. The range forecast is from the most optimistic to the pessimistic is 4.8 to 5.05 percent.However what ever the result, RBI will leave the interests alone , provided the Rupee does not take a turn for the worse and RBI has to intervene before that.
