Wholesale prices declined at a faster-than-expected annual rate of 2.33 per cent in March, their fifth straight fall, on the back of tumbling oil and manufacturing prices, Government data showed on Wednesday.
The data compared with a 1.95 per cent year-on-year fall forecast by economists in a Reuters poll and a provisional 2.06 per cent decline in February.
The reading for January wholesale price inflation was revised to -0.95 per cent from -0.39 per cent earlier.
