With Iran war-driven disruption pushing energy prices higher, European governments are pressing the European Commission to respond with profit caps on energy companies, arguing the surge is already adding pressure to households and inflation. Spain’s Economy Minister Carlos Cuerpo said Saturday that finance ministers from Spain, Germany, Italy, Portugal and Austria had signed a letter to the Commission. Cuerpo made the letter public in an online post after the ministers agreed on the proposal, which calls for a bloc-wide mechanism for dealing with what they described as distortions in energy markets.

In the letter, dated Friday, the ministers pointed to how the conflict in the Middle East has raised oil prices and increased costs across Europe. “The conflict in the Middle East has caused oil prices to rise, placing a significant burden on the European economy and on European citizens,” the letter said. The ministers said they want the European Commission to make a “similar EU-wide contribution instrument,” arguing that the current environment includes both market distortion and “fiscal constraints.”

The ministers framed the policy goal as burden sharing, not only cost relief. “It is important to ensure that this burden is distributed fairly,” the letter said, adding that those who profit from the war’s consequences should contribute to easing the impact on the broader public. The letter said that with “current market distortions and fiscal constraints,” the Commission should develop the new instrument swiftly.

Cuerpo and his counterparts linked their push to earlier European action during the energy shock after Russia’s full-scale invasion of Ukraine. The letter recalled that in 2022 the EU imposed a “solidarity contribution” that included caps on excess energy profits, and it urged the Commission to build on that approach. The ministers’ proposal comes as Europe’s high dependence on imported oil and gas leaves it exposed to external supply shocks.

European inflation has been sensitive to energy and fuel costs, according to figures cited alongside the ministers’ letter. The annual inflation rate in the euro zone’s 21 countries rose to 2.5% in March from 1.9% in February, driven largely by higher oil prices. For reference at the same time period, FRED’s vintage data show annual inflation in the United States measured by the consumer price index at 2.43400411037322% and core CPI at 2.4724624767640226%.

The energy pressure also reflects shipping disruptions tied to the Iran conflict. The ministers’ letter and the wider reporting around it pointed to Iran blocking most tanker traffic through the Strait of Hormuz, a key chokepoint for about 20% of global oil and gas. Europe’s exposure to changes in fuel supply is one reason the ministers argued that policy action should not wait as markets adjust.

EU Energy Commissioner Dan Jorgensen warned this week that the disruption could keep energy prices elevated. He said the closure means fuel prices are unlikely to “go back to normal in a foreseeable future,” indicating that the situation could last beyond a short-term spike.

While the letter does not specify how the EU-wide windfall tax would be implemented, it sets out the ministers’ view that profit caps should target companies benefiting from the war-linked price surge. In their account, the goal is to reduce the risk that inflationary pressure and higher energy bills increasingly fall on households as markets remain distorted.
