Global energy prices are projected to increase dramatically,  the biggest price jump in commodities in nearly half a century, the World Bank has warned.

According to the bank’s April Commodity Markets Outlook report, global energy prices, which have already seen a dramatic surge due to ongoing Covid-19 lockdowns in China and the Russia-Ukraine conflict, are expected to surge by 50.5% in 2022.

“This amounts to the largest commodity shock we’ve experienced since the 1970s. As was the case then, the shock is being aggravated by a surge in restrictions in trade of food, fuel, and fertilizers,” the World Bank’s Vice President for Equitable Growth, Finance, and Institutions, Indermit Gill, said in a statement on Tuesday.

The report points out that sanctions imposed on Russia have effected global trade in commodities, triggering huge energy-price increases. Food prices are projected to rise by 22.9% this year as well, the most since 2008, as wheat prices jump 40% to record highs.

Metal prices are expected to swell by 16% before easing next year but will reportedly remain at elevated levels.

According to the report, surging commodity prices have already contributed to inflation levels not seen in more than 40 years in the US, and a record 7.5% jump in consumer prices in Europe.

“These developments have started to raise the specter of stagflation. Policymakers should take every opportunity to increase economic growth at home and avoid actions that will bring harm to the global economy,” Gill said.
