Since the financial crisis of 2008 and the Great Recession, investors and executives have grown accustomed to a world of low interest rates and low inflation. No longer. In 2021, inflation began rising sharply in many parts of the world, and in 2022 the U.S. saw its worst inflation in decades.

Summary.
What causes inflation? There is no one answer, but like so much of macroeconomics it comes down to a mix of output, money, and expectations. Supply shocks can lower an economy’s potential output, driving up prices. An increase in the money supply can stoke demand, driving up prices. And the expectation of inflation can become a self-fulfilling cycle as workers and companies demand higher wages and set higher prices.
