The wholesale price index (WPI) rose 5.19 percent year-on-year last month, its slowest pace since February, and compared with a 5.10 percent annual rise forecast by economists in a Reuters poll. In June, prices rose 5.43 percent from a year earlier.
Surging costs for vegetables, fruit and milk led to a faster-than-expected 7.96 percent on year rise in retail prices in July, a governmentdata showed on Tuesday. Poor rains in some parts of the country has pressured food prices and vegetable prices, for example, are up 68 percent since March.

New Delhi estimates it needs to invest $9 billion in the cold supply chain by March 2016 to handle growing output of fruit and vegetables. That is more than 10 times the $822 million allocated in Modi's maiden budget last month, and far more than the government can afford.
