Euro zone inflation surges to 2.5% as energy shock from Iran conflict hits

Euro zone inflation jumped to 2.5% in March, smashing through the European Central Bank's 2% target and marking the fastest annual price growth since late 2023. The preliminary flash estimate from Eurostat released on Tuesday showed a sharp acceleration from 1.9% in February, though it came in marginally below the 2.6% median forecast in a Reuters poll of economists.

Energy prices swing violently after Hormuz closure

The entire upside surprise came from energy. The energy component of the harmonised index of consumer prices leapt to 4.9% year on year in March from a 3.1% decline in February, a swing of eight percentage points in a single month. The trigger was the near-total closure of the Strait of Hormuz by Iran at the end of February, following the US and Israeli military operation against Iranian nuclear and military sites. Roughly a fifth of global oil and liquefied natural gas shipments pass through the strait, and the abrupt loss of those volumes sent benchmark gas prices at the Dutch TTF hub up more than 60% in the first three weeks of March.

Europe's exposure is structural. Despite years of rhetoric about strategic autonomy, the continent remains a net importer of both gas and oil. The latest supply crunch arrives just as the EU is accelerating its exit from Russian pipeline gas, forcing buyers to compete globally for cargoes of liquefied natural gas. The United States supplied 58% of EU LNG imports last year, a share that has tripled since 2021, but American export capacity is near its limit and Asian buyers are bidding aggressively for the same cargoes.

Underlying price pressures show mixed signals

Strip out energy and the picture is less alarming. Services inflation, the component the ECB watches most closely for domestically generated price pressure, eased to 3.2% from 3.4% in February. Food, alcohol and tobacco inflation also ticked down to 2.4% from 2.5%. Non-energy industrial goods inflation held at 0.6%. The core rate, which excludes energy, food, alcohol and tobacco, is likely to print around 2.6% when the full breakdown is published in mid-April, down from 2.7% in February.

That core reading matters. The Governing Council has repeatedly said it will look through temporary energy shocks provided they do not feed into wages and services prices. So far, the pass-through appears limited. Negotiated wage growth in the fourth quarter of 2025 ran at 3.8%, broadly stable on the previous quarter, and forward-looking indicators such as the Indeed wage tracker have softened in recent months.

Lagarde signals readiness to hike if needed

Christine Lagarde, president of the European Central Bank, said last week that the central bank was watching regional data closely and would respond with interest rate hikes if necessary, even if a surge in inflation proved to be short-lived. The phrasing was deliberate. By refusing to pre-commit to looking through the shock, Lagarde keeps the option of a June rate increase on the table, something money markets had largely priced out before the Hormuz crisis. Swaps now imply a roughly 40% probability of a 25 basis point move at the 5 June meeting, up from less than 10% a month ago.

The ECB's own staff projections, revised in March, now see headline inflation averaging 2.6% for 2026 as a whole, with growth downgraded to 0.9% from 1.3% in December. That combination, stagnating output and above-target inflation, is the classic stagflationary bind that central bankers dread. The March staff macros assume the Hormuz disruption persists through the second quarter before a gradual reopening. If the closure drags on, both forecasts will deteriorate further.

A war of choice, not necessity, in European eyes

The political context compounds the economic damage. Across European capitals, the US-Israeli operation against Iran is seen as a war of choice rather than necessity. That perception matters because it shapes the policy response. Had the supply shock stemmed from a Russian escalation in Ukraine, the EU would likely have triggered coordinated demand-reduction measures and emergency gas storage rules. With the disruption originating from an ally's military action, the political will for collective European demand management is weaker, leaving the adjustment to fall almost entirely on price.

The sentiment data already shows the hit. The European Commission's economic sentiment indicator fell 4.2 points in March, the largest monthly drop since the early weeks of the pandemic. Consumer confidence, employment expectations and the composite PMI output index all turned down sharply. The services PMI, which had been holding above 50, slipped to 48.7, signalling contraction. Manufacturers report lengthening delivery times and rising input costs, but order books are thinning as customers delay spending.

The LNG scramble exposes infrastructure gaps

Europe's dash for LNG has revealed bottlenecks that no amount of spot purchasing can solve. Regasification capacity in north-west Europe is running at over 90% utilisation. The German terminals at Wilhelmshaven, Lubmin and Brunsbüttel, all floating storage and regasification units deployed since 2022, are operating at nameplate capacity. New capacity at Stade and the expansion of the Dutch Gate terminal will not come online before 2027. Until then, every additional cargo requires someone else to go without, pushing prices higher globally.

The European Commission's latest gas demand reduction report, published in February, showed EU member states collectively cut gas use by 18% between August 2022 and January 2026 compared with the five-year average. That cushion is largely exhausted. Industrial demand has already been destroyed in energy-intensive sectors, fertiliser, aluminium, glass, and residential demand is inelastic at current temperatures. Further savings would require rationing, a step no government has yet countenanced.

Markets weigh a second wave of price pressures

Joshua Mahony, chief market analyst at Scope Markets, described the March print as evidence of a second wave of price pressures only just beginning to take hold. He noted that energy has switched from being a key driver of disinflation to the key driver of above-target inflation. For central bankers, the task ahead is to ascertain whether this is simply something they can look beyond or a driver of higher rates to come. That assessment will dominate the ECB's 16-17 April meeting in Frankfurt, where new staff projections will incorporate the full quarter of Hormuz disruption.

The governing council is divided. Hawks led by Isabel Schnabel and Joachim Nagel argue that credibility demands a pre-emptive hike to anchor expectations. Doves including Fabio Panetta and François Villeroy de Galhau insist that monetary policy cannot fix a supply shock and that tightening would deepen the recession unnecessarily. Lagarde has so far steered a middle course, but the March data narrows the path. If April's core reading holds above 2.5%, the case for a June move becomes hard to resist.
