"In economies where such overheating pressures remain high, inflation remains above target and inflation expectations have continued to rise, such as in China, India, and Korea, the current pace of monetary tightening remains appropriate," the IMF said in its Regional Economic Outlook for the Asia-Pacific.
The RBI has already hiked interest rates 12 times since March, 2010, to control inflation, which is currently hovering near the double-digit mark.
With the rise in key interest rates by 350 basis points over the past 20 months resulting in a slowdown in industrial output, there has been a widespread demand for a pause in the rate hikes. The RBI is slated to conduct its second quarter policy review on October 25.
"Inflation has been driven by commodity prices, but also in many economies by sustained demand pressures," the IMF said.
It said that commodity price rise has fed to generalised inflation in countries like the Hong Kong special administrative region, India, Indonesia, Korea, Malaysia and Thailand.
"Inflation expectations have also risen since the first quarter of 2011 in a number of economies," it said.
The report further said that Asian economies are facing a rising risk to growth on account of increased financial worries in the euro area and the growth slowdown in the US.
