Energy Shock From Iran War Spreads Across Europe and U.S.
LONDON (Dispatches) -- European natural gas prices have surged to their highest level since early 2023 as renewed U.S. strikes on Iran and Iran’s retaliation against American bases across West Asia revive fears that the war could choke off critical energy supplies ahead of winter.
Dutch front-month gas futures climbed above €75 per megawatt-hour on Wednesday, their highest level since January 2023,
while Brent crude moved above $95 a barrel after renewed fighting around the Strait of Hormuz. Reuters reported that oil prices have now been driven higher by mounting concern over supply disruptions, while shipping data show traffic through the strategic waterway has fallen sharply.
The danger extends far beyond the battlefield.
The Strait of Hormuz is a critical artery for global energy markets. The U.S. Energy Information Administration has estimated that disruptions to the waterway have affected more than 10 billion cubic feet per day of global LNG supplies, roughly one-fifth of the world’s LNG trade, with Qatar accounting for most of the missing volumes.
That has left Europe and Asia competing for alternative cargoes at precisely the moment when European utilities are preparing for winter. QatarEnergy has already faced prolonged disruption to LNG shipments, while European storage levels remain below seasonal targets, increasing the pressure on buyers to secure replacement supplies.
The result is a global scramble for fuel.
India has already been forced to pay more than $23 per million British thermal units for some September LNG cargoes, among the highest prices recorded by the country’s buyers in years. European utilities face the same problem: every cargo diverted to one market is potentially unavailable to another.
In the United States, the shock is showing up most directly at the pump.
Gasoline prices have remained substantially above their pre-war levels, while diesel has been hit particularly hard. Reuters reported that U.S. diesel futures reached a 52-month high as the conflict disrupted refinery and fuel markets.
The economic consequences do not stop with motorists.
Higher fuel prices feed directly into transportation, aviation, manufacturing, agriculture and food costs. Airlines face more expensive jet fuel; trucking companies pay more for diesel; manufacturers confront higher energy and logistics bills; and consumers ultimately absorb much of those costs through higher prices.
Economists have warned that the war could therefore produce a particularly difficult combination of slower growth and persistent inflation. The Washington Post reported in August that the average U.S. household could face roughly $1,000 in additional costs from the war, according to one economist.
Stanford economists have similarly examined the impact of higher gasoline costs on household purchasing power and the broader U.S. economy.
The pressure is already visible in financial markets. The Financial Times reported that the latest energy surge pushed European gas above €75/MWh and raised fears of prolonged inflation, while bond yields climbed as investors reassessed the likelihood of higher-for-longer interest rates.
That creates a particularly difficult dilemma for central banks. If energy prices remain elevated, inflation can become entrenched even as households and businesses cut spending in response to higher costs.
The broader danger is that an extended Hormuz disruption could turn an energy shock into a wider economic shock.
Oil, LNG, shipping, insurance, fertilizer, food and industrial costs are all interconnected. Reuters has reported that Brent crude has averaged around $90 a barrel in 2026, sharply above last year’s average, while diesel and jet-fuel markets have also suffered from supply disruptions.
For governments and consumers, the central question is no longer simply how long the fighting will last. It is how long the world’s energy system can absorb the consequences.
With commercial traffic through Hormuz severely disrupted, winter approaching in the northern hemisphere and Iran and the United States trading threats of further escalation, markets are pricing in the possibility that the energy shock will not be brief.
