The Wholesale Price Index-based inflation was 12.41 percent in August and 11.80 percent in September last year. This year, the Wholesale Price Index (WPI) touched a record high of 15.88 percent in May.
September is the 18th consecutive month of double-digit WPI inflation.
"Inflation in September 2022 is primarily contributed by rising in prices of mineral oils, food articles, crude petroleum & natural gas, chemicals & chemical products, basic metals, electricity, textiles etc. as compared to the corresponding month of the previous year," an official statement said.

The RBI mainly looks at retail inflation to frame monetary policy.
Retail inflation remained above the Reserve Bank's upper tolerance threshold of 6 percent for the ninth month in a row and was at a 5-month high of 7.41 percent in September, as per data released earlier this week.
To tame stubbornly high inflation, the RBI has hiked the key interest rate four times this year to 5.90 percent -- the highest since April 2019.
