Why did the ECB raise interest rates in May 2026, and what specific inflation data triggered this decision?

The ECB raised its main deposit rate from 2% to 2.25% — its first rate hike since 2023 — in response to rising eurozone consumer price inflation, which increased to 3.2% in May 2026 from 3% in April 2026, exceeding the ECB’s 2% target; this acceleration was directly attributed to higher energy costs driven by the war in Iran, which pushed oil prices above $90 a barrel and threatened to fuel broader price increases across manufacturing and retail sectors.

What did ECB President Christine Lagarde say about the risks posed by the Iran war to inflation and economic growth, and how did the ECB revise its growth forecasts?

Christine Lagarde stated that the war’s ‘full implication for medium-term inflation and growth will depend on the intensity and duration of the energy price shock, as well as the scale of its indirect and second-round effects’, and warned that ‘prolonged disruption of energy supplies could increase energy prices further and for longer than currently expected’; accordingly, the ECB downgraded its eurozone growth forecast to 0.8% for 2026 and 1.2% for 2027, from previous estimates of 0.9% and 1.3%, citing ‘downside risks to the growth outlook, mainly owing to the war in the Middle East’.
