ECB Holds Rates at 2% as Iran War Drives Energy Prices Higher and Revives Inflation Fears

FRANKFURT, Germany — The European Central Bank left its key interest rate unchanged at 2% on Thursday, shelving a long-anticipated cut after war in Iran sent oil and gas prices sharply higher and rekindled fears of inflation across the eurozone.

At its meeting in Frankfurt on March 19, the ECB’s Governing Council kept all three of its policy rates steady and warned that the conflict in the Middle East has “made the outlook significantly more uncertain, creating upside risks for inflation and downside risks for economic growth.”

The decision marks a sudden pause in the ECB’s gradual shift away from the aggressive tightening it used to tame the post‑pandemic price surge. As recently as early February, many investors and economists expected a quarter‑point reduction in March, arguing that inflation had returned to the 2% target and that borrowing costs could begin to normalize.

Instead, new projections released alongside Thursday’s decision show higher inflation and weaker growth in 2026 than the ECB had forecast three months ago, a change officials explicitly linked to the surge in energy prices following the escalation of fighting involving Iran, the United States and Israel.

“Inflation had been converging to our target, but the latest energy price developments require us to reassess the balance of risks,” ECB President Christine Lagarde said at a news conference. “The war in Iran and related disruptions to oil and gas markets are adding to inflation in the short term and weighing on confidence and activity.”

From expected cut to “hawkish hold”

Headline inflation in the 20‑nation euro area stood at 1.9% in February, essentially on target, after a steep decline from double‑digit levels in 2022 and early 2023. In December, Eurosystem staff projections predicted inflation averaging 1.9% in 2026 and 1.8% in 2027, assuming relatively stable energy prices.

On that basis, several major banks, including Bank of America, publicly forecast one last 25‑basis‑point cut at the March meeting. Market pricing in early February also pointed to high odds of a reduction.

That consensus unraveled after Feb. 28, when U.S. and Israeli forces launched large‑scale airstrikes on Iranian targets. Iran responded with missile and drone attacks on Israel and Gulf energy infrastructure and signaled it could disrupt traffic through the Strait of Hormuz, a choke point for roughly a fifth of the world’s crude exports and a major share of liquefied natural gas shipments.

Benchmark Brent crude oil, trading near $70 a barrel before the conflict escalated, climbed above $100 in early March and briefly topped $119 on Thursday before pulling back. European natural gas prices nearly doubled in the space of days as traders fretted over the security of LNG cargoes from Qatar and other Gulf suppliers.

As energy markets swung, expectations for ECB policy swung with them. By mid‑March, analysts said a cut was no longer likely, and some began to warn that if high energy prices persisted, the next move in rates could even be up rather than down.

“The war in Iran has introduced a shock that is both inflationary and recessionary,” said Carsten Brzeski, chief economist for the eurozone at ING. “That is exactly the kind of scenario central banks fear most.”

Lagarde did not rule out future cuts but stressed that decisions will be taken “meeting by meeting” and depend on incoming data, particularly on wages, underlying inflation and the duration of the energy shock.

Higher inflation, weaker growth

The ECB said its updated staff projections now point to stronger price pressures and slower output growth in 2026 than foreseen in December. Officials did not publish a detailed breakdown at the news conference, but Lagarde said the revision “mainly reflects higher assumptions for oil and gas prices and their pass‑through to consumer prices.”

At the same time, she said, longer‑term inflation expectations remain “well anchored” around 2%, and there is no evidence so far of a broad wage‑price spiral.

Philip Lane, the ECB’s chief economist, had warned earlier this month that a prolonged conflict in the Middle East that disrupts energy supplies could lead to a “substantial spike” in inflation and a “sharp drop in output” in the eurozone. Joachim Nagel, president of Germany’s Bundesbank and a member of the Governing Council, said a long war “would push up inflation in the euro area and hurt growth,” adding that for now “the risks to price stability are more concerning than the risks to activity.”

Those concerns are rooted in Europe’s experience over the past three years. After Russia’s full‑scale invasion of Ukraine in 2022, natural gas prices in Europe soared, contributing to inflation above 10% and triggering emergency fiscal support and industrial shutdowns. The ECB initially characterized much of the surge as temporary before raising rates at the fastest pace in its history.

Officials have since said they do not want to repeat the mistake of underestimating energy‑driven inflation. Thursday’s decision to keep rates on hold, even with inflation near target, reflects that caution.

Europe’s lingering energy vulnerability

While the eurozone economy is less energy‑intensive than it was during the oil shocks of the 1970s, it remains a major net energy importer and relies heavily on seaborne oil and LNG after cutting pipeline gas imports from Russia.

“The conflict around the Strait of Hormuz matters a lot for Europe,” said Simone Tagliapietra, an energy expert at the Bruegel think tank in Brussels. “The region has diversified away from Russian pipelines, but that has increased reliance on global LNG and maritime routes that now look more fragile.”

In response to the latest spike, members of the International Energy Agency agreed on March 11 to release 400 million barrels of oil from emergency reserves in an effort to stabilize markets. So far, that has only partially offset fears of longer‑term supply disruptions.

Higher energy costs are already showing up at the pump and on household bills. Consumer groups in Italy and Spain say they are seeing renewed pressure on family budgets, especially among lower‑income households that had only just recovered from the last cost‑of‑living crisis.

For energy‑intensive industries such as chemicals, steel, glass and fertilizers, the combination of higher input prices and borrowing costs stuck at restrictive levels threatens to delay investment and could revive concerns about factories relocating outside Europe.

Political and global ramifications

National governments now face renewed pressure to cushion the blow. During the 2022 energy crisis, many eurozone countries rolled out fuel tax cuts, direct subsidies and windfall taxes on energy companies. Finance ministers must now weigh similar measures against stretched public finances and new European Union fiscal rules meant to rein in deficits.

Any large‑scale fiscal response could complicate the ECB’s job. Generous subsidies might shield households but also prop up demand, potentially keeping inflation higher for longer.

The ECB’s decision also fits into a broader pattern among major central banks. On Wednesday, the U.S. Federal Reserve kept its benchmark rate unchanged and cited a “highly uncertain” outlook tied in part to the Iran conflict and its impact on energy prices and global risk appetite. The Bank of England, meeting the same day as the ECB, held its main rate at 3.75% after previously signaling that cuts were on the horizon, warning that the surge in oil and gas prices had “stoked renewed concerns about inflation.”

Despite the similar stance, Europe may have less room to maneuver than the United States or the United Kingdom because of its greater dependence on imported energy and its proximity to the conflict.

“The euro area is once again at the epicenter of an energy shock it did not create and cannot control,” said Maria Demertzis, a senior fellow at Bruegel. “Monetary policy can respond to the inflation part of the shock, but it cannot produce gas or oil.”

A decision shaped beyond Frankfurt

What happens next will depend largely on developments far from the ECB’s glass towers on the banks of the Main. A swift de‑escalation in the Middle East and a normalization of shipping through the Strait of Hormuz could allow energy prices to retreat, easing pressure on inflation and reopening the door to rate cuts later in the year.

A prolonged or widening conflict, by contrast, could entrench higher energy costs, forcing the ECB to keep policy tight — or even tighten further — even as growth slows, raising the specter of stagflation.

For now, Lagarde and her colleagues are signaling patience.

“We will not pre‑commit to any particular rate path,” she said. “Our task is to ensure that inflation returns to 2% over the medium term. The current situation, while difficult, does not change that objective. It does, however, remind us that the path back to price stability is not linear and is subject to shocks beyond our control.”

The rate cut many in Europe had expected this spring has been postponed indefinitely, not by data from within the eurozone, but by missiles, drones and tankers in a distant but economically critical waterway.
