Earlier this week, Reserve Bank in its first quarterly review said, inflation is expected to touch 5 per cent by the end of March 2010.
The apex bank said the transitory negative WPI may not persist beyond a few more months.
As a result, with uncertain monsoon and rising global commodity prices inflation is projected at around 5 per cent by March, 2010. This is higher than the projection of 4 per cent made in the annual policy statement, RBI said.
The monetary policy efforts should be aimed at ensuring price stability so as to keep inflation in the range of 4-4.5 per cent with a medium term objective of 3 per cent, RBI added.
