Which one is it?
No single cause explains the 2021-2023 inflation surge, and economists still disagree about the weights. A worldwide surge in inflation began in mid-2021 and many countries saw their highest rates in decades. It has been attributed to several causes, including pandemic dislocation, supply-chain disruption, the fiscal and monetary provided by governments and central banks, and .
The supply-chain story starts when the pandemic recession ended. Consumers shifted spending towards goods, which strained so that supply could not meet demand, and prices rose. In November 2021, inflation in the United States was 14.9% for but only 3.8% for services.
Then came energy. In early 2022 the effect of Russia's invasion of Ukraine on oil, gas, fertiliser and food prices exacerbated the situation. In Europe, gas prices rose by more than 450% and electricity by 230% in less than a year.
The debate had a moment of drama: in 2021, Janet Yellen called the risk of inflation small and manageable, and Fed chairman Jerome Powell thought it would be , even as inflation rose above 6 percent. All central banks except the Bank of Japan responded by aggressively raising interest rates. At the peak, the US had its highest inflation since 1981 and the its highest since records began in 1997. In the UK, inflation hit 11.1% in October 2022.

Recap
No one cause explains it: supply shocks, energy prices, stimulus and (disputed) pricing power all appear in the accounts.
💡 A trick to remember it · A pandemic bottleneck, a war's energy shock and a stimulus tailwind: three gusts, one storm.
Surprising fact · In November 2021 US inflation was 14.9% for durable goods but only 3.8% for services.
