ECB raises rates for first time since 2023 as Iran war fuels eurozone inflation

A 'look through' strategy is not a robust response.
Deutsche Bank's chief European economist on why the ECB abandoned its wait-and-see approach to energy shocks.

For the first time in nearly three years, the European Central Bank has moved to tighten its grip on money, raising its deposit rate to 2.25% as the war in the Middle East keeps oil prices high and eurozone inflation climbing past 3%. The decision marks a quiet but consequential turning point: the era of hoping conflict-driven energy shocks would simply pass has given way to the harder work of actively defending price stability. Yet the economy the ECB is trying to protect is itself weakening, and the question of how much medicine a slowing patient can bear now hangs over every future decision.

  • Eurozone inflation reached 3.2% in May — oil above $90 a barrel since the Iran conflict began is pushing costs through manufacturers and retailers faster than policymakers had hoped.
  • The ECB's earlier bet that energy disruptions would prove temporary and self-correcting has collapsed, forcing a strategic reversal that carries its own risks for an already fragile economy.
  • Officials are deliberately moving early, haunted by their slow response to post-Ukraine inflation in 2022, when hesitation allowed price pressures to entrench before the bank acted.
  • Growth forecasts have been cut to just 0.8% for 2026, unemployment is rising, and analysts warn that markets may be too optimistic in pricing two further hikes by spring 2027.
  • The ECB's move sets it apart from the Bank of England and the Federal Reserve, both expected to hold — signalling that Europe bears the sharpest edge of the Middle East energy shock.

The European Central Bank raised its main deposit rate by a quarter point to 2.25% on Wednesday — its first tightening move in nearly three years — as inflation driven by the Middle East conflict forces a reckoning with price stability across the eurozone. After months of hoping a US-Iran peace deal might contain energy costs without requiring intervention, ECB leadership concluded that waiting was no longer tenable.

Eurozone consumer prices climbed to 3.2% in May, well above the bank's 2% target. Oil has held stubbornly above $90 a barrel since the war began — up from roughly $70 beforehand — and those costs are already spreading through the broader economy as businesses adjust prices heading into summer. The ECB's governing council had previously considered simply absorbing the energy shock rather than responding to it. That position has now been abandoned.

ECB President Christine Lagarde acknowledged the deep uncertainty ahead, noting that how far inflation spreads depends on how long energy prices stay elevated. The bank also raised its refinancing rate to 2.4%. Financial markets are pricing in two more hikes by next spring, though some economists believe that may prove too optimistic given the deteriorating backdrop.

The move is partly a lesson learned. The ECB drew criticism for reacting too slowly after Russia's invasion of Ukraine in 2022, allowing inflation to build before the bank responded. This time, officials are attempting to act before price pressures entrench — even as growth forecasts for 2026 were cut to 0.8% and Lagarde described the risks to the outlook as tilted "to the downside."

Deutsche Bank's chief European economist called the decision a signal to major central banks everywhere that passively accepting energy shocks is no longer credible — while cautioning that the ECB may have limited room to keep raising rates before the weakening economy forces a pause. The Bank of England and the Federal Reserve are both expected to hold in the coming weeks, leaving the ECB to navigate alone the sharpest tension in modern monetary policy: whether fighting inflation and protecting growth can truly be done at the same time.

The European Central Bank made its first move to tighten monetary policy in nearly three years on Wednesday, raising its main deposit rate by a quarter point to 2.25% as inflation pressures from the Middle East conflict force a reckoning with price stability across the eurozone. The decision signals a shift in strategy: after months of hoping that a US-Iran peace deal would contain energy costs without requiring rate increases, ECB leadership has concluded that waiting is no longer viable.

Eurozone consumer prices climbed to 3.2% in May, up from 3% the month before, pushing well past the central bank's 2% target. The culprit is straightforward. Oil prices have remained stubbornly above $90 a barrel since the war began—up from roughly $70 before the conflict—and those higher energy costs are already rippling through the economy as manufacturers and retailers adjust prices to protect margins heading into the summer months. The ECB's governing council had considered simply "looking through" these energy shocks in March, betting that temporary supply disruptions would not require a policy response. That calculus has changed.

Christine Lagarde, the ECB president, acknowledged the uncertainty now shadowing the eurozone's economic outlook. The full weight of the war on inflation and growth, she said, depends on how long energy prices stay elevated and how widely those costs spread through the broader economy. The central bank also raised its main refinancing rate—the rate at which commercial banks borrow from it—to 2.4% from 2.15%. Financial markets are already pricing in two additional increases by next spring, though that expectation may prove optimistic.

The timing of this move is deliberate. The ECB faced criticism for moving too slowly in 2022 after Russia's invasion of Ukraine, allowing inflation to build momentum before responding. This time, officials are attempting to get ahead of the curve, tightening policy while the economy still has room to absorb the shock. Yet the economic backdrop is deteriorating. The central bank downgraded its growth forecast for 2026 to 0.8%, down from 0.9%, and for 2027 to 1.2%, down from 1.3%. Unemployment is rising. Growth is slowing. The risks to the outlook, Lagarde said, are "to the downside."

Mark Wall, chief European economist at Deutsche Bank, called the decision a significant moment—not just for the ECB but as a signal to other major central banks that passively accepting energy shocks is no longer a credible strategy. Yet he cautioned that markets may be overestimating how much room the ECB has to keep raising rates. With the economy weakening, another hike in September might be the limit before the central bank has to pause and assess the damage. The question now is whether fighting inflation and protecting growth can be done simultaneously, or whether the ECB will soon face a choice between the two.

Meanwhile, the Bank of England is expected to hold rates steady at 3.75% next week, and the Federal Reserve is also likely to pause, despite US inflation running at 4.2%—the highest in the Group of Seven. The ECB's decision to act first underscores how acutely the eurozone feels the energy shock from the Middle East, and how fragile the balance has become between controlling prices and sustaining economic momentum.

The full implication 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.

This is a significant moment. 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.

Why did the ECB decide to raise rates now, after holding steady for so long?

Model

They were hoping the war would end quickly and energy prices would fall back down. When that didn't happen and inflation kept climbing, they realized waiting was making things worse. They'd been burned before by moving too slowly in 2022.

Inventor

But doesn't raising rates make borrowing more expensive? Won't that slow the economy even more?

Model

Exactly. That's the trap they're in. If they don't raise rates, inflation keeps eating away at people's savings and purchasing power. If they do raise rates, they risk tipping a weakening economy into something worse. They're trying to act early enough that smaller increases do the job.

Inventor

What's the real risk here—that inflation spirals, or that growth collapses?

Model

Both, honestly. But the ECB seems more worried about inflation right now because they think they can control that. Growth is already slowing on its own. The danger is if energy prices stay high for years, not months. Then you've got a real problem.

Inventor

Why didn't other central banks move at the same time?

Model

The US and UK are watching to see if this works. They've got different inflation pictures and different economic situations. The eurozone is particularly exposed to energy shocks because it depends heavily on imported oil and gas. The others can afford to wait a bit longer.

Inventor

What happens if the ECB raises rates two more times and the economy still doesn't improve?

Model

Then they stop and hope they've done enough to anchor inflation expectations. But if inflation stays high and growth keeps falling, they'll be stuck—unable to tighten further without risking real damage, but unable to loosen without losing credibility on prices.
