A steeper-than-expected hike in the key rates by the Reserve Bank of India took the markets by surprise, as a result of which they took a sharp dip post announcement.
The Sensex erased all gains and plunged to a low of 18,482 -- down around 450 points from the day's high of 18,944 - in the last half hour of trades.
The index finally ended at 18,518 - down 353 points. The Nifty ended down 105 points at 5,575.
Continuing its anti-inflationary stance, Reserve Bank of India raised the repo rate by 50 basis points (bps) to 8% from 7.5% and the reverse repo rate was raised from 6.5% to 7%.
The Central Bank, however, kept the Cash Reserve Ratio (CRR) unchanged.
Last time, the Central Bank raised rates by 50 basis points was two months back in May 2011.
Thereafter, the benchmark indices saw a bigger fall and ended with losses of over 2 per cent each.
In fact, the markets went on to extend losses for another two trading days.
"There are signs that growth is beginning to moderate, particularly in interest sensitive sectors. But there is no signs of a broad-based slowdown", said RBI Governor D Subbarao.
He added that a moderation in demand is necessary to bring down inflaiton and that the US debt standoff will add risks to the global capital flows.
FY12 GDP growth forecast was kept unchanged at 8%. The RBI stated that the FY12 fiscal deficit target is a challenge and that this move has been taken to control inflation which is imperative to sustain growth.
"This is an aggressive posture taken by RBI considering the inflation scenario. Very clearly shows that RBI is willing to sacrifice growth to tame inflation. Industry will suffer and hope that this will be the last of such hikes," Sudip Bandyopadhyay, MD & CEO, Destimoney Securities.
"There is a complete lack of coordination between the fiscal policy & monetary policy action. We have to acknowledge that global commodity prices & supply side issues cannot be addressed with monetary policy action & extremely high interest rates without impacting growth," said Aneesh Srivastava, CIO -- IDBI Federal Insurance Company.
