Raghuram Rajan surprised everyone with a more-than-expected rate cut of 50 basis points in the monetary policy yesterday. When a governor who has been reluctant to cut rates thus far does something unexpected, you wonder if it is an exasperated reaction or a desperate punt. So far, the governor’s main concern has been inflation, and if he is reassured on that front, one would have expected a 25 basis point cut. But a 50 basis point cut at a time when the world is speculating a rate hike by the Federal Reserve might be a signal that he is equally worried about dismal growth.
