The European Central Bank has raised interest rates for the first time since 2023 as policymakers respond to renewed inflation pressure driven by higher energy costs linked to the war in Iran.
The ECB increased its main deposit rate from 2% to 2.25%, a quarter-point move that signals growing concern inside the central bank that the latest energy shock could push inflation further above target. The bank also raised the rate on its main refinancing operations, which commercial banks use to borrow from the ECB, from 2.15% to 2.4%.
The decision comes after eurozone inflation rose to 3.2% in May, up from 3% in April and well above the ECB’s 2% target. Higher oil and gas prices have become a central concern for policymakers as the Iran conflict continues to disrupt energy markets and raise costs for businesses and consumers.
ECB President Christine Lagarde said the outlook remains uncertain because the effect of the war will depend on how long the energy shock lasts and how deeply it spreads through the wider economy.

“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,” Lagarde said.
The rate increase marks an important shift in ECB policy. Until now, the central bank had held rates steady while officials watched whether energy prices would stabilize or whether diplomatic efforts involving Iran would reduce pressure on global oil markets. But with oil prices still elevated and inflation rising again, the ECB decided that waiting carried risks.
The move is likely to be seen as an attempt to avoid the criticism the ECB faced in 2022, when many economists argued it was too slow to respond to inflation after Russia’s invasion of Ukraine. This time, policymakers appear more willing to act early before higher energy prices become embedded in wages, consumer prices, and business contracts.
Financial markets now expect further rate rises, with some investors pricing in two additional increases by next spring. However, economists are divided on how far the ECB can go without damaging an already fragile economy.
The central bank also lowered its growth forecasts for the eurozone, projecting growth of 0.8% in 2026 and 1.2% in 2027. Those figures are slightly weaker than previous estimates and reflect the challenge facing policymakers: inflation is rising, but economic growth is slowing.
Lagarde said the risks to growth are tilted to the downside, mainly because of the war in the Middle East and the volatile global policy environment. She warned that prolonged disruption to energy supplies could push prices even higher and keep inflation elevated for longer than expected.
The ECB’s decision shows how central banks are once again being forced to react to geopolitical shocks. Energy costs affect nearly every part of the economy, from transportation and manufacturing to food production and household utility bills. When oil and gas prices rise sharply, businesses often pass those costs to consumers, creating broader inflation pressure.
For households across the eurozone, higher interest rates could mean more expensive loans, mortgages, and credit. For businesses, borrowing costs may rise at a time when demand is already weakening. The ECB is trying to prevent inflation from becoming entrenched, but tighter monetary policy could also weigh on investment and growth.
That tension is why some economists believe the ECB’s tightening cycle may be limited. Mark Wall, chief European economist at Deutsche Bank, described the move as significant because it is the first ECB rate hike since 2023 and the first major central bank hike directly responding to the current Middle East energy shock. But he also warned that markets may be overestimating how many additional increases will follow.
The Bank of England and U.S. Federal Reserve are also being watched closely. Both are expected to consider the impact of higher energy prices at upcoming meetings. The Bank of England is expected to leave rates unchanged for now, while the Federal Reserve may also hold steady despite inflation remaining elevated in the United States.
The ECB’s decision could influence other central banks if energy-driven inflation continues spreading. If oil prices remain above recent averages, policymakers around the world may face the same difficult choice: raise rates to fight inflation or hold back to protect growth.
For Europe, the situation is especially sensitive because the region has already experienced major energy disruptions in recent years. The eurozone has worked to reduce dependence on unstable supply chains, but energy prices remain a major vulnerability. A prolonged conflict involving Iran could keep pressure on shipping, oil supply, and business costs well into the year.
The ECB has made clear that future decisions will depend on incoming data. Officials are likely to watch inflation, wage growth, energy prices, unemployment, and business surveys before deciding whether to raise rates again.
For now, the message is clear: the ECB is no longer willing to simply look through the energy shock. It is acting early in an effort to stop inflation from becoming a longer-term problem.
Why It Matters
This matters because higher ECB rates affect borrowing costs across the eurozone. Mortgages, business loans, government debt, and consumer credit can all become more expensive when rates rise.
It also matters because the Iran war is now having direct economic consequences in Europe. Higher energy prices are feeding into inflation, forcing the ECB to tighten policy even as growth slows.
What Comes Next
The next key question is whether the ECB raises rates again later this year. Markets expect more hikes, but some economists believe the weak growth outlook may limit how far the central bank can go.
Policymakers will closely watch oil prices, inflation data, wage growth, and any diplomatic progress related to Iran. If energy costs keep rising, pressure for another rate increase could grow.
Reuters reported that the ECB raised interest rates to get ahead of inflation pressure linked to the Iran war and potential disruption in oil supplies.
The European Central Bank put up interest rates to head off higher inflation induced by the Iran war. Chris Hare of HSBC told Reuters they could bring them back down, but that depends on whether the disruption to oil supplies drags on https://t.co/MWrPPlZBAC pic.twitter.com/AkRN4Ra1gf
