Indian Speed Bumpers
Speed Breakers in India are planned in a way to punish people who drive fast rather than as a warning for them to slow down. We won't find any signs of a speed breaker untill we are bumped off by them.
Same is the case with RBI rising the CRR. Though it was not completely unexpected, the recent hike has surprised many. A warning sign of interest rate hike would itself have slowdown inflation without toppling the growth rate.
A long term plan on interest rates announced well before would really help SMEs, in fact, everyone to plan better.
