What the announcement says<\/h2>\n
\n

Has the latest energy shock triggered a new wave of food price increases? To find out, we\u2019ve used innovative AI tools to track changes in price setting by supermarkets. So far, the rise in the repricing momentum has been weaker than in 2022, following Russia\u2019s invasion of Ukraine.<\/p>\n

When an energy price shock hits the economy, food prices are among the first to rise. That has immediate consequences for consumers. Food accounts for around 20% of expenditure in the euro area consumption basket used to calculate the Harmonised Index of Consumer Prices (HICP). And this share is even larger for low-income households.[1] As such, changing food prices play a key role in influencing households\u2019 perceptions and expectations surrounding inflation.[2] Meanwhile, from a monetary policy perspective, it is crucial to understand the pattern of a repricing wave. Policymakers need to grasp how quickly firms adjust prices, how widespread those adjustments are and whether they might generate persistent inflationary pressures. But how can we capture repricing dynamics affecting consumers in real time when large shocks happen?<\/p>\n

The ECB has created a tool, the Daily Price Dataset (DPD), to follow supermarket price developments as they unfold. Since 2022 the DPD has provided information about how firms reset prices and on the likelihood that inflation arising from the shock will be strong, broad-based and persistent.[3] Our tool indicates that the ongoing resetting of food prices triggered by the energy shock arising from the war in the Middle East is weaker than that in 2022 following the Russian invasion of Ukraine. The data show that initially food repricing increased fairly broadly but then stabilised. This contrasts with what happened during the 2022 energy shock, when the repricing wave continued to rise.<\/p>\n

Following a cost shock, firms decide whether they will adjust their prices and by how much. They make decisions based on factors such as the size of the shock, competitors\u2019 prices and the costs of changing prices (so-called \u201cmenu costs\u201d). If shocks are small, firms will not deviate from their regular repricing plans, but if they are large, they will want to adjust prices earlier than planned (so-called \u201cstate-dependent pricing\u201d). In this case, we will observe an increase in the frequency of price increases, leading to non-linear effects on the inflation response that are relevant for monetary policy.<\/p>\n

Two aspects are especially informative. The first is how often firms raise and lower prices, known as the extensive margin. The second is the size of those price changes, known as the intensive margin. Together, these reveal the answer to the following question: is observed inflation the outcome of a few, very large price increases or of a broad-based repricing wave across products and retailers?<\/p>\n

To address this question, ECB staff in the PRISMA research network developed the DPD, working with the BIS Innovation Hub and the Deutsche Bundesbank under Project Spectrum.[4] The dataset uses daily online supermarket prices and an AI-based classifier that maps retailers\u2019 product descriptions onto consumption categories underlying the HICP basket.<\/p>\n

It measures the resulting repricing frequencies monthly to remove short-lived fluctuations, including temporary sales. However, because the tool collects underlying observations every day, it can update the estimate for the current month continuously throughout the month.[5]<\/p>\n

2026 versus 2022: what does the DPD tell us?<\/p>\n

The frequency of food price increases rose in March 2026, shortly after the energy shock hit (Chart 1, panel a). However, this increase was much smaller than during the inflation surge of 2022. In contrast, the gap between the frequency of price increases and decreases is small. The average size of price increases changed relatively little, similar to the 2022 episode (Chart 1, panel b).<\/p>\n
