Food repricing after 2026 energy shock remains weaker than in 2022
Food repricing after the Middle East war energy shock has stabilised rather than broadened as it did in 2022, according to the European Central Bank (ECB). Daily supermarket data show little evidence so far of persistently more frequent price changes.
March increase loses momentum
The frequency of food price increases rose in March 2026, but by much less than after Russia's invasion of Ukraine in 2022.
The gap between the frequency of increases and decreases remained small, while the average size of increases changed little in both episodes.
In 2026, repricing frequencies neither rose nor widened sequentially across food categories; their distribution was narrower and maximum frequencies generally lower.
In 2022, categories where at least 10 percent of product prices increased monthly expanded across the food basket and remained widespread for months.
Food represents around 20 percent of euro area HICP expenditure, with a larger share for low-income households, and influences inflation perceptions and expectations.
Daily prices reveal monthly patterns
ECB staff in the PRISMA research network developed the Daily Price Dataset (DPD) with the Bank for International Settlements Innovation Hub and Deutsche Bundesbank under Project Spectrum.
Used since 2022, it applies an AI classifier to map online supermarket product descriptions to Harmonised Index of Consumer Prices (HICP) categories.
Monthly repricing measures exclude temporary sales and update daily; aggregates use HICP expenditure weights.
Large cost shocks can prompt firms to reprice earlier than planned, generating non-linear inflation responses.
Frequency matters beyond inflation
The blog finds little evidence so far of persistently more frequent food repricing after the 2026 shock.
It stresses that inflation alone cannot distinguish broader repricing from larger individual increases.
Energy-shock effects depend on the shock's composition and prevailing economic conditions.
