Commenting on inflation figures, Planning Commission Deputy Chairman Montek Singh Ahluwalia said it indicates a distinct downturn on inflation which is welcome.
"They (RBI) should certainly consider it because it is very clear that the underline inflationary pressure is softening," he added.
Industry chamber Ficci demanded that RBI should consider a rate cut and persuade banks to pass on rate cut benefits to borrowers. "With the downward trend in the prices holding on, RBI can consider a cut in the policy rate in the forthcoming monetary policy review," it said.
Analysts, however, were of the view that it may be difficult for the Reserve Bank to cut rates in view of the sharp decline in the value of the rupee against the US dollar.
