ECB blog post that uses the Daily Price Dataset of online supermarket prices and AI classifiers to assess whether the current energy shock has triggered a new wave of food price increases. The frequency of price increases rose in March 2026, but far less than in 2022, and then stabilised.
Key points
- Food accounts for around 20% of the HICP basket, more for low-income households
- The average size of price increases has changed little, as in 2022
- Unlike in 2022, the repricing wave has not kept rising
Who is affected
Inflation and monetary policy analysis, food retail

An ECB blog (the ECB is the euro area's central bank) uses AI to track online supermarket prices every day, to see whether the energy shock has sent food prices soaring again. Price rises picked up in March 2026, but far less than in 2022, and then levelled off. It matters because food is about 20% of the basket used to measure inflation, and more for lower-income households.
