NEW DELHI (Reuters) - India's wholesale price index fell for the second time in three months in January as oil prices slumped, bolstering prospects for further interest rate cuts by the central bank.
The wholesale price index (WPI) unexpectedly fell 0.39 percent last month from the same period a year earlier, its biggest decline since June 2009, government data showed on Monday.
The fuel price index tumbled 10.69 percent on-year.
Analysts in a Reuters poll had predicted a 0.4 percent year-on-year gain in wholesale prices, slightly faster than a provisional 0.11 percent increase in December.
The reading for November WPI inflation was revised down to -0.17 percent from 0.0 percent earlier.
The data comes days after annual consumer inflation came in at 5.11 percent, well below the central bank's medium-term target of 6 percent, and the trade deficit shrunk to a 11-month low.
