The Reserve Bank mostly tracks the Consumer Price Index- based inflation for its monetary policy decisions.
The CPI or retail inflation for September rose to 4.41 per cent, from 3.74 per cent in the previous month. The rise in retail inflation as well as the marginal upward movement of wholesale inflation is unlikely to have a bearing on the monetary policy of RBI.
The central bank has signalled that it would wait for sometime before cutting interest rates. Last month, RBI had reduced interest rates by more than expected 0.50 per cent and said it expects CPI inflation to reach 5.8 per cent in January 2016.
