MUMBAI, India — India’s worrisome core inflation rose to 7.52 percent in November, driven by soaring food and fuel prices, government data showed Monday. The highest level in more than a year increases pressure on the central bank to raise interest rates once again this week.

The wholesale price index was up from 7 percent in October. The sharp increase was the highest since September 2012 and was led by food prices jumping by 19.9 percent over the previous November, dashing hopes that favorable monsoon rains would slow the runaway food inflation. Prices for fuel were also up 11.1 percent. Higher prices for food and fuel hit the hundreds of millions of poor Indians living on $2 per day particularly hard because they spend roughly half of their income on the staple items.

The grim inflation numbers increase the likelihood that the Reserve Bank of India will raise interest rates when it meets on Wednesday. The central bank’s new chief, Raghuram Rajan, has made battling inflation a priority since taking office two months ago, hiking the key interest rate twice since September to its current 7.75 percent.

It’s unclear, though, whether the interest rate hikes have much effect on food inflation. Some analysts argue that Indian food prices are largely structural, driven by an inefficient distribution system that results in 30 percent of produce spoiling before reaching markets.

Rajan has been under pressure to freeze or even cut interest rates to try to revive stalling growth in India’s wider economy. Asia’s third-largest economy expanded by 4.8 percent in the July- September quarter, far below the 8 percent rate the country averaged a few years ago.

Some business leaders have argued for lower interest rates to encourage businesses to borrow and invest and consumers to spend.
