ECB: Iran War Likely to Deepen Economic Impact on Euro Zone Consumers

Impact of Geopolitical Conflicts on Euro Zone Consumer Behavior

FRANKFURT, May 29 (Reuters) - Euro zone consumers, already scarred by the Ukraine war, have changed their attitudes more quickly as a result of the upheaval of the Iran war, European Central Bank research showed on Friday, meaning the economic hit could be deeper and faster.

Russia's invasion of Ukraine in February 2022 caused an energy crisis and inflation from which Europe had largely recovered, but then U.S.-Israeli airstrikes on February 28 launched a war on Iran that has led to unprecedented energy supply disruption.

ECB Research Findings

ECB researchers have analysed whether euro zone consumers have become more responsive to the economic impact of such geopolitical upheaval and say the evidence suggests they have.

Consumer Response to Price Changes

Drawing from the ECB's own Consumer Expectations survey, ECB economists including Olivier Coibion found that consumers immediately increased their attention to price changes when the Iran conflict started, even though inflation was still around 2%, the ECB's target level.

Nearly half of the respondents in the CES said they were paying attention to price changes in March 2026, a similar proportion to January 2023, when euro area inflation at 8.6% made concern in theory far more likely.

Double Scarring Effect on Consumers

Two Scars May Reinforce Each Other

TWO SCARS MAY REINFORCE EACH OTHER

"This evidence suggests that consumers are experiencing the war in Iran with a potential 'double scar'," the ECB researchers said in their blog, which does not necessarily reflect the bank's official view.

"These two scars may reinforce each other and are likely to shape consumer expectations and behaviour in the coming months, as conflicts and heightened macroeconomic uncertainty persist." 

Implications for Consumer Sensitivity and Economic Outlook

The economists said such scars, or memories of financial stress, can increase consumers’ sensitivity to new shocks.

"This makes stagflationary scenarios – rising prices and declining growth – more pronounced and persistent in their beliefs. And it could reinforce macroeconomic uncertainty and ultimately influence consumer spending," the economists said.

Oil Prices and ECB Policy Response

Oil Price Fluctuations

Oil prices, which have a major inflationary impact, have fallen on hopes of a peace deal, but surged to well above $120 a barrel in April as a result of the Iran war.

ECB's Likely Actions

Key Takeaways

  • ECB data show consumer sensitivity to prices in March 2026 matched January 2023 levels, despite inflation being near target (~2 %)
  • Oil surged past $120/barrel amid Strait of Hormuz disruptions, intensifying energy‑price shocks across Europe
  • ECB poised to raise rates at June meeting as inflation hits 3 % and growth stalls, with broader financial vulnerabilities mounting due to prolonged war
