Hormuz closure triggers 12.5% energy inflation spike

A narrow channel between Iran and Oman now carries Europe’s next inflation test. Iran says the Strait of Hormuz is closed, while Washington disputes whether traffic has stopped; markets do not need an airtight blockade to move. They need danger, delay and scarce replacement cargoes.

The reason is scale. About 20 million barrels a day of oil and petroleum liquids crossed Hormuz in 2024, roughly 20% of global consumption, while around one-fifth of global LNG trade used the same route, according to the EIA. Most of those flows go to Asia, not Europe. But Europe buys energy in global markets, so a chokepoint serving China, India, Japan and South Korea can still lift diesel, gas, fertiliser and industrial-input costs from Rotterdam to Silesia.

The Shock Moves Through Prices First

Europe’s exposure is not mainly direct barrels from the Gulf. Germany took only 6.1% of its crude imports directly from the Middle East in 2025, while its overall energy import dependence stood at 67%, Destatis notes. That is the core tension: low direct exposure can coexist with high price exposure.

The first channel is expectations. Futures prices move when traders expect tighter supply, higher freight costs or higher war-risk premia. BNP Paribas has warned that only part of normal Hormuz flows can be bypassed by pipeline, leaving oil markets quick to price scarce prompt supply through the Brent curve BNP Paribas.

The second channel is pass-through from wholesale energy to households and firms. The ECB’s June projections say higher crude and refined-product prices pass fully and quickly into liquid fuels, while gas and electricity move more slowly and differently across countries because contracts, hedging, tariffs and taxes vary ECB projections. That is why the same external shock becomes a fuel-price squeeze in one country, a power-price problem in another, and an industrial-margin problem somewhere else.

Who Pays, And Where

The burden falls first on users who cannot easily wait or substitute. Commuters, hauliers, airlines, chemical plants, fertiliser producers and food processors face the fastest pressure. Eurostat’s industry data show EU industry consumed 8,835 petajoules of energy in 2024, with electricity at 33.3%, natural gas at 31.9%, and oil products still at 10.4% Eurostat. This is not only a petrol-station story.

Households feel it through heating, electricity and transport. EU households used 9.54 million terajoules of energy in 2024, with gas at 29.4%, electricity at 26.9%, and space heating alone at 61.5% of household energy use Eurostat. Gas-heated homes and drivers lose sooner than urban households with district heating and good public transport.

Germany looks exposed because it combines industry, imported energy and thin summer storage. NDR reported gas storage near 35% on 9 June, around 25 percentage points below the 2017-21 average, while BDEW put German storage at 35.3% on 9 June and the THE spot price at €50.3/MWh on 10 June NDR, BDEW. The Netherlands is different: it is less just a victim than a transmission hub, because Dutch TTF futures anchor European gas pricing through ICE Endex ICE.

Spain has buffers, not immunity. Its regasification capacity and renewables help, but La Vanguardia reported national energy dependence at 68.4% of final consumption, with the PNIEC target at 50% by 2030 La Vanguardia. Italy and Poland sit closer to the delayed channels: refined products, fertiliser, transport costs and food prices.

Policy gains are narrower. LNG exporters outside the Gulf, refiners with inventories, storage operators and traders able to redirect cargoes benefit from scarcity. Governments gain no easy option. Subsidising fuel shifts the bill from pumps to budgets. Letting prices pass through protects public finances but hits voters and firms. Tightening monetary policy can contain expectations, but it cannot open Hormuz.

That is why the ECB’s latest forecast matters. It projects euro-area headline inflation peaking at 3.4% in Q3-Q4 2026 and energy inflation at 12.5%, then pairs the shock with a 25-basis-point rate rise and a warning that fiscal support should be temporary, targeted and tailored ECB projections, ECB statement. Europe is being pushed into the old energy trap: protect incomes, protect budgets, protect price stability. It cannot fully protect all three at once.

The Open File

The hardest fact remains the physical status of the Strait. French reporting has described a collapse from about 160 ships a day to 11, but that figure remains weak without independent vessel-tracking confirmation Le Grand Continent. Expert commentary also leaves room for continued passage, which supports a severe quasi-blockade more than a verified zero-transit closure Les Clés du Moyen-Orient.

The next watchpoints are therefore practical: actual tanker movements, war-risk insurance, Qatari LNG cargoes, European storage fills, diesel prices and fertiliser costs. Europe does not need to run out of energy for Hormuz to hurt. It only needs to keep buying fossil fuels in a market where danger has become part of the price.
