The wholesale price-based inflation rose to a four-month high of 14.55 per cent in March, mainly due to hardening of crude oil and commodity prices, even though vegetables witnessed easing of price pressures.

As per the government data released on Monday, WPI inflation has remained in double digits for the 12th consecutive month beginning April 2021.

"The high rate of inflation in March, 2022 is primarily due to rise in prices of crude petroleum and natural gas, mineral oils, basic metals, etc, owing to disruption in the global supply chain caused by the Russia-Ukraine conflict." the Commerce and Industry Ministry said in a statement.
