The Reserve Bank of India unexpectedly cut key lending rates on Thursday in an effort to boost growth in the Asia's third-largest economy.
The central bank was not scheduled to issue a rate decision, and the move took economists and analysts by surprise.
The RBI reduced its key repo rate by 0.25 percentage points to 7.75%, the first such cut in nearly two years. The rupee surged on the news, as did stocks trading in Mumbai.
RBI governor Raghuram Rajan said in a statement that with inflation under control, the bank felt it had room to act.
"These developments have provided headroom for a shift in the monetary policy stance," he said.
Daniel Martin, an economist at Capital Economics, said that more rate cuts are likely. He expects additional central bank actions over the next year or so that will bring the repo rate down to 7%.
"We think today's surprise move marks the start of a loosening cycle," he said. "The economy could certainly use some support, with the industrial sector, in particular, clearly struggling to gain any momentum."
