ECB’s Lane Warns Iran Conflict Could Trigger Eurozone Stagflation
Chief economist says prolonged Middle East war threatens substantial inflation spike and sharp output drop as oil prices surge 10% amid Strait of Hormuz disruption.
European Central Bank Chief Economist Philip Lane cautioned that a prolonged Iran conflict could deliver a double blow to the Eurozone: a substantial spike in inflation alongside a sharp drop in economic output, resurrecting the stagflation spectre that last haunted the continent during the 2022 energy crisis.
Lane told the Financial Times that a sustained war in the Middle East could cause both elevated Inflation and reduced growth, with previous ECB sensitivity analyses showing such a scenario would lead to a substantial spike in Energy-driven inflation and a sharp drop in output if energy supplies from the region face persistent disruption. The warning comes as U.S. and Israeli military action against Iran widened Monday, with no immediate end in sight and oil prices jumping over 10%.

The mechanics are straightforward but the policy implications are agonising. Lane noted that a jump in energy prices puts upward pressure on inflation, especially in the near-term, while such a conflict would be negative for economic activity. A December ECB analysis suggests that a permanent oil price spike of this magnitude could lift inflation by 0.5 percentage point and lower growth by 0.1 percentage point—asymmetric impacts that leave central bankers with no clean policy response.
The Bank currently enjoys unusual room to manoeuvre. Eurozone inflation now stands at 1.7%, below the ECB’s 2% target, and the deposit facility rate sits at 2.00% following a series of cuts through 2025. But that cushion evaporates quickly if energy prices sustain elevated levels. Lane emphasised that the scale of impact and implications for medium-term inflation depend on the breadth and duration of the conflict, acknowledging the ECB would monitor the situation.
Europe’s Hormuz Dependency Exposed
The conflict has disrupted shipping in the Gulf, a crucial fuel source for Europe, resulting in an immediate rise in energy prices on financial markets. The Strait of Hormuz handles 20% of global oil trade, and approximately 20% of global oil passes through this strait—significant for European countries that increased reliance on these imports following their move away from Russian energy.
According to Modern Diplomacy, countries such as Britain, Italy, Belgium, and Poland depend heavily on liquefied natural gas that routes through the Strait of Hormuz. The immediate market response was severe: oil prices surged nearly 8% to around $78 a barrel, while natural gas prices rose by 19%. European gas prices on the Dutch TTF hub jumped as much as 45% to around €46 per megawatt-hour after Qatar announced it had halted liquefied natural gas production linked to the North Field gas reservoir following an attack on its facilities.
Europe’s energy import dependence remains structural despite diversification efforts since 2022. Crude oil and natural gas still make up nearly 60% of the EU’s energy mix, while pipelines account for 85% of natural gas imports but only 20% of oil. The bloc replaced Russian pipeline gas primarily with U.S. LNG—EU imports of U.S. LNG rose from 21bcm in 2021 to an estimated 81bcm in 2025, meaning EU countries sourced 57% of their LNG imports from the U.S.—creating what some analysts term a new geopolitical dependency.
The Stagflation Dilemma
Lane’s comments surface a scenario the ECB hoped to avoid: simultaneous inflation acceleration and growth deceleration that would force a choice between price stability and supporting economic activity. The situation may prompt the ECB and the Bank of England to rethink interest rate decisions, potentially delaying further rate cuts until the situation stabilises, according to analysis from Modern Diplomacy.
The ECB’s policy stance offers limited flexibility. The ECB tends to look past energy-induced volatility in prices as long as fluctuations do not impact longer-term expectations and do not seep into underlying inflation via second-round effects. That framework worked when energy shocks were transitory. A prolonged conflict changes the calculus.
In a mild $80 scenario, inflation would return to around 2%, while a $130 shock lifts 2026 inflation by 1.3 percentage points, according to ABN AMRO analysis cited by FXStreet. Under a sustained high-price scenario, inflation would be 0.5% higher in 2026 and 2027 and 0.3% above baseline in 2028, whereas economic growth would be only 0.1% lower in each year—the asymmetry that makes policy response so fraught.
| Metric | 2022 (Russia-Ukraine) | 2026 (Iran scenario) |
|---|---|---|
| Growth Impact | -1.0pp | -0.1pp (ECB estimate) |
| Inflation Impact | +2.0pp | +0.5pp (ECB estimate) |
| Initial Oil Price Move | ~40% spike | ~10% spike (Monday) |
| Policy Response | Aggressive rate hikes | Wait-and-see (so far) |
The 2022 shock, when Russia’s attack on Ukraine pushed up energy costs, lowered growth by 1 percentage point and lifted inflation by 2 percentage points, according to a European Commission study cited by U.S. News. Current projections suggest a milder hit, but those assume the conflict remains contained.
Rate Path in Jeopardy
The ECB held rates steady at its February 2026 meeting, keeping the main refinancing rate at 2.15%, with the deposit facility at 2.0% and marginal lending rate at 2.4%. Market expectations had coalesced around an extended pause. No interest rate change is priced at all for the rest of 2026, according to U.S. News reporting from early March.
That consensus now faces stress. Around 85% of economists surveyed by Reuters in January said the ECB would leave rates unchanged over the rest of 2026. But those surveys preceded the Iran escalation. ECB policymaker Lane noted that even when taking out energy price volatility, inflation is running above the 2% medium-term target, adding this is not an environment where he sees an argument in favour of taking a bit of risk on inflation, according to investingLive.
The growth backdrop had been improving. Both the European Commission and the ECB expect growth to moderate to 1.2% in 2026 amid geopolitical tensions and trade policy uncertainty, before rebounding slightly to 1.4% in 2027. An energy shock that materialises could push those estimates materially lower while simultaneously lifting inflation projections—the definition of stagflation.
“The scale of the impact and the implications for medium-term inflation depend on the breadth and duration of the conflict.”

What to Watch
Three variables will determine whether Lane’s warning materialises into policy action. First, the duration of Strait of Hormuz disruption—tanker traffic through the waterway has effectively ceased after insurance coverage was withdrawn over the weekend, but whether this persists beyond days into weeks or months is critical. Second, the path of natural gas prices, which remain at relatively low storage levels across the EU—currently below 30% capacity compared with around 40% at the same point last year, with Germany’s facilities at 20.5% and France’s at 21%—leaving less buffer for extended supply disruption.
Third, second-round effects. The ECB’s tolerance for energy-driven inflation depends on it remaining contained to headline measures without feeding into wage demands or long-term expectations. Market-based expectations for longer-term inflation are broadly unchanged, providing some comfort. But analysts suggest effects on inflation and growth depend heavily on the duration and expansion of the conflict—while a short conflict may have minimal impacts, a prolonged situation could potentially elevate inflation and reduce growth rates.
The next ECB meeting is scheduled for March 19, 2026. By then, the outlines of this conflict—and the energy market response—should be clearer. If oil sustains above $90 and European gas remains elevated, the Bank will face its most difficult policy decision since the 2022 energy crisis: whether to prioritise fighting inflation or supporting growth. Lane’s comments suggest the ECB is already war-gaming that scenario.
