The European Central Bank announced a quarter-point rate hike on Thursday, lifting its key interest rate to 2.25% amid mounting inflation pressure from the ongoing U.S.-Iran war.
Markets had been pricing in a near-100% chance of the ECB raising rates by at least 25 basis points ahead of its June Governing Council meeting, according to LSEG data.
The ECB’s Governing Council stated the decision was made specifically to counter inflationary pressures generated by the conflict in the Middle East.
“The war in the Middle East is generating inflation pressures, and the decision to raise rates is robust across a range of scenarios mapping out how the shock might evolve and affect the medium-term outlook for the euro area,” the bank said in its statement.
The central bank also revised its inflation forecasts upward, now expecting headline euro zone inflation to average 3% in 2026, cooling to 2.3% in 2027 and reaching the 2% target by 2028.
Officials attributed the higher inflation outlook to expectations of elevated energy prices feeding through into the costs of food, goods, and services across the bloc.
Growth forecasts were simultaneously cut, with the ECB now projecting euro zone expansion of just 0.8% in 2026, followed by 1.2% in 2027 and 1.5% in 2028.
The downgrade reflected “a more pronounced impact of the war on commodity markets, real incomes and confidence,” according to the Governing Council’s official statement.
ECB President Christine Lagarde addressed reporters Thursday afternoon, warning that conditions remain highly unpredictable for both inflation and economic growth across the region.
“The outlook remains uncertain, with upside risks for inflation, and downside risks for economic growth. We are not pre-committing to a particular rate path,” Lagarde said.
“The full implications of the war 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,” she added.
The Iran war, which recently crossed the 100-day mark, has caused severe global energy supply disruptions following the closure of the Strait of Hormuz and destruction of regional energy production facilities.
Euro zone inflation climbed to 3.2% in May, flash data showed, driven by higher energy costs pushing the region further above the ECB’s 2% target.
The euro zone economy grew by just 0.1% in the first quarter of 2026, underscoring the fragile economic backdrop against which the ECB is tightening policy.
Mark Wall, chief European economist at Deutsche Bank, described the decision as “a significant moment,” noting its broader implications for global central bank policy.
“Not only is this the first ECB hike since 2023, it is also the first hike by one of the major global central banks in response to the energy shock,” Wall said in a research note.
“The ECB is saying that a ‘look through’ strategy is not a robust response. The question is how far can this tightening cycle go? Not far, is our answer. One more hike in September and that’s it,” he added.
Neil Birrell, chief investment officer at Premier Miton, said the move was unsurprising given the inflation environment, though he noted growth risks remain present.
“Encouragingly, they don’t see much risk to GDP, although growth expectations are already muted. This is likely to be followed by more rate hikes this year, depending on the data, but it’s hard to think this is the end of the policy move,” Birrell said.
The yield on the 10-year German bund was 2 basis points lower by 2:50 p.m. in Frankfurt, while the euro held flat against both the dollar and the British pound.
