ECB Warns Iran Conflict Could Rekindle Inflation If Hormuz Energy Flows Are Hit

FRANKFURT, Germany — Europe’s hard‑won progress in taming inflation is facing a new threat from the Middle East, as the European Central Bank’s chief economist warned that a prolonged war involving Iran and disruptions to oil and gas shipments through the Strait of Hormuz could deliver a fresh energy‑driven shock to the euro area.

Philip Lane said a “lengthy” conflict that seriously interferes with energy flows risked a “substantial spike” in prices alongside a sharp drop in output, according to an interview published Monday. His comments come as oil and gas markets react to escalating hostilities around the narrow waterway, one of the world’s most important energy chokepoints.

A stress test scenario returns to the policy debate

Lane’s warning effectively lifts an internal stress test off the ECB’s shelves and brings it into live policy debate. In a scenario published in late 2023, the central bank’s staff examined what would happen if roughly one‑third of the oil and gas that normally sails through Hormuz were blocked.

In that case, oil prices in the model surge toward $130 a barrel, euro‑area inflation climbs by nearly a full percentage point and economic growth weakens by about two‑thirds of a point compared with the bank’s baseline forecast.

Those numbers, while not a prediction, underline how vulnerable the 20‑nation currency bloc remains to energy supply shocks just as headline inflation has fallen back close to the ECB’s 2% target.

Hormuz: a narrow channel with global consequences

The backdrop to Lane’s remarks is a rapid escalation in the Iran conflict. After large‑scale U.S. and Israeli strikes on military and energy targets in Iran in recent weeks, Tehran has declared the Strait of Hormuz closed and threatened to attack commercial vessels entering the area. Regional media and shipping industry reports say drones and missiles have hit facilities in Saudi Arabia, Kuwait and Qatar, raising fears of a broader energy crisis.

The Strait of Hormuz, a channel less than 40 kilometers wide at its narrowest point between Iran and Oman, normally carries about 20 million barrels of crude and condensates each day — roughly 30% of global seaborne oil trade and around one‑fifth of the world’s oil consumption. It also handles close to a fifth of global liquefied natural gas exports, mostly from Qatar.

In recent days, dozens of tankers have paused or rerouted rather than attempt the passage. Several leading marine insurers have suspended or sharply curtailed war‑risk coverage for voyages through the Gulf, a step that significantly raises costs for shipowners and can make transits unviable. Shipping sources have reported damaged tankers and at least one fatality linked to attacks.

Markets move, but not yet to worst‑case levels

Energy markets have reacted fast, if not yet to the extremes embedded in the ECB’s scenario. Benchmark Brent crude has risen into the low $80s per barrel, up roughly 7% to 13% over a handful of trading sessions. European gas prices have jumped about 50% from recent levels, touching multi‑year highs on some hubs.

By contrast, the central bank’s 2023 stress test assumes oil moves to almost $130 a barrel and European wholesale gas prices climb roughly three‑quarters above its benchmark path, levels that would echo or exceed the turmoil seen after Russia’s full‑scale invasion of Ukraine.

“For now, this is a risk scenario, not the baseline,” Lane told the Financial Times, while cautioning that the impact on Europe would depend heavily on “how long the conflict lasts” and the scale of any damage to infrastructure and shipping. He indicated the ECB would not adjust interest rates in response to a short‑lived price spike but could not ignore a persistent shock that filtered into wages and broader price‑setting.

What it means for interest rates and inflation

Lane’s intervention highlights a delicate moment for monetary policy in the euro area. After lifting borrowing costs at record pace through 2022 and 2023 to counter the post‑pandemic and Ukraine‑driven surge in inflation, the ECB has gradually cut its key deposit rate to 2.0% as price pressures eased.

Euro‑area inflation stood at 1.9% in February, with underlying or “core” inflation at 2.4% and services inflation at 3.4%, according to official estimates.

Those figures had bolstered expectations among investors that the ECB would continue to lower rates this year. Market pricing now implies the deposit rate will remain on hold at the bank’s next policy meeting, and derivatives have pared back bets on aggressive easing. Some traders have even begun to price in the possibility of a renewed tightening later in the year if energy prices rise further.

Lane, a former governor of Ireland’s central bank and the ECB’s chief economist since 2019, has frequently argued that central banks should “look through” short‑lived, purely supply‑driven spikes in energy prices when setting policy. He has also stressed, however, that persistent shocks that seep into wage demands and non‑energy prices require a response to keep inflation expectations anchored.

The ECB’s stagflation risk

The ECB’s Middle East escalation scenario reflects those concerns. In the exercise, staff projected that a partial closure of Hormuz would leave overall euro‑area inflation 0.9 percentage points higher in the first year and 0.4 points higher in the second, compared with its baseline projections. Real gross domestic product growth would drop 0.7 percentage points in the first year and 0.3 points in the next.

The modeling assumes that higher oil and gas prices feed directly into household energy bills and firms’ costs, while heightened geopolitical uncertainty weakens investment and consumption and reduces foreign demand for European exports.

Economists say such a combination of higher inflation and weaker growth — often labeled stagflation — is among the most difficult environments for central banks, which must weigh support for activity against the risk of losing control of prices.

“Central banks are much better equipped institutionally than in the 1970s, but the trade‑offs don’t disappear,” said a euro‑area economist at a major bank, who asked not to be named discussing internal projections. “If oil goes close to where the ECB’s scenario has it, and if that lasts, they may have to keep rates higher for longer even as growth slows.”

Households, industry and politics could feel the fallout

The renewed energy threat lands as many European households and businesses are still recovering from the surge in gas and electricity prices that followed Russia’s reduction of pipeline flows in 2022. Governments spent hundreds of billions of euros on subsidies, tax cuts and price caps to cushion the blow, policies that helped support demand but also strained public finances.

Another spike could reignite debates over who should bear the cost of shielding consumers and industry. Energy‑intensive manufacturers in sectors such as chemicals, metals and paper, already under pressure from global competition and the green transition, could again face tough choices about cutting production or passing on costs.

Higher fuel prices also risk stirring political tensions. In several euro‑area countries, protests over living costs have contributed to gains for populist parties critical of sanctions, military engagement abroad or climate policies that they argue increase energy bills.

Analysts note that Europe is better positioned in some ways than during the last crisis. The continent has expanded its capacity to import liquefied natural gas, filled storage facilities more aggressively ahead of winter and cut demand through efficiency measures. The global economy is also less oil‑intensive than during the shocks of the 1970s, meaning a given rise in crude prices has a smaller direct bite on output.

Still, the centrality of Hormuz to global energy flows gives the current crisis a different character from the earlier gas confrontation with Moscow. While Russian pipeline cuts mainly hit Europe, a serious and sustained disruption in the Gulf would ripple simultaneously across Asia, Europe and beyond.

What to watch next

For now, the ECB is signaling patience as it watches to see whether shipping lanes reopen and prices stabilize or whether the worst‑case models creep closer to reality. The bank’s next set of staff projections and any updated scenario analysis will be closely scrutinized for clues about how its Governing Council is weighing the Iran risk.

In the meantime, Lane’s decision to publicly highlight the $130‑oil scenario underscores that Europe’s battle against inflation, once thought to be entering its final phase, may be far more dependent on events in a congested waterway between Iran and Oman than on any single indicator in Frankfurt.
