"The high rate of inflation in October is primarily due to the rise in prices of mineral oils, basic metals, food products, crude petroleum and natural gas, chemicals and chemical products etc, as compared to the corresponding month of the previous year," the ministry said in its review of 'Index Numbers of Wholesale Price in India' for October.
"The month over month change in WPI index for October 2021 (as compared to September 2021) was 2.28 per cent," it said.

"Broad-based input price pressures amid a depreciating INR, as well as a spike in vegetable and electricity prices, pushed the WPI inflation to a higher-than-expected five month high 12.5 per cent in October 2021, with the core inflation rising to a fresh all time high of 11.9 per cent," said Aditi Nayar, Chief Economist, ICRA.
"Other than non-food primary articles and minerals, all the commodity sub-groups recorded an uptick in YoY inflation in October 2021 relative to the previous month."
According to Sunil K. Sinha, Principal Economist, India Ratings and Research: "This is the seventh consecutive month in which wholesale inflation has stayed at double-digit level."
"A sharp surge in the momentum effect of 2.3 percentage point was the reason behind rise in wholesale inflation in October 2021. This primarily came from the fuel and power inflation which jumped to 37.18 per cent in October from 24.81 per cent in September 2021. Within fuel and power group, electricity prices showed a sharp jump to 10.8 per cent in October 2021 from a deflation of 6.74 per cent in September 2021."
