Why inflation expectations matter
With surging energy prices now pushing inflation higher, there is much focus on how inflation expectations will respond. The concern is that if the public comes to believe that energy prices will remain high for some time, or that central banks are too slow to respond, inflation expectations will rise.
That matters for central banks because inflation expectations directly influence actual inflation. If the public expects prices to rise, firms will set higher prices and workers will demand higher wages, pushing inflation up independently of other factors. Keeping expectations anchored close to the inflation target is therefore one of the most important tasks a central bank faces.
The ECB’s monitoring framework
The ECB is therefore watching closely the inflation expectations data from its own Consumer Expectations Survey (CES), which measures expectations at three horizons: 12 months ahead, three years ahead, and five years ahead.
Chart 1 shows these data since April 2022, when five-year expectations were first collected, alongside actual HICP (harmonized index of consumer prices) inflation in the euro area.
