How could the IRGC actions and tensions in the Strait of Hormuz affect Europe?

Likely What happens if… A possibility worth considering, not a forecast.

Hormuz tensions could raise energy costs and disrupt European trade The ongoing tensions and military actions around the Strait of Hormuz have severely disrupted global maritime trade, which directly impacts Europe. The waterway, through which about a fifth of the world's seaborne oil normally moves, has seen flows of crude and petroleum liquids drop nearly 30% compared to a year earlier. This disruption, combined with the elevated risk of vessel incidents, has caused war-risk insurance premiums to rise significantly, reaching between 7.5% and 10%. These factors contribute to higher operational costs and reduced supply stability for European economies reliant on global energy imports.

How it reaches Europe

The facts so far

As reported. Each one links to where it comes from.

  • Flows of crude and petroleum liquids through Hormuz fell to 14.6 million barrels per day in the first quarter of 2026, from 20.4 million barrels per day a year earlier, a drop of nearly 30%.hindustantimes.com
  • War-risk insurance premiums rose to between 7.5% and 10% by late July.hindustantimes.com
  • Recent shipping data showed only eight vessels crossing the strait on one day, compared with a pre-war average of around 130 to 140 vessels a day.moneycontrol.com
  • Brent crude traded at about 66 dollars a barrel before the war.hindustantimes.com

Why it matters

Europe is heavily dependent on stable global energy supplies and the free flow of maritime trade through critical chokepoints like the Strait of Hormuz. Any sustained disruption to this route directly threatens the continent's energy security and contributes to inflationary pressures and economic instability.

Globally, the conflict has already caused major disruptions, with the International Energy Agency calling the instability among the largest in oil-market history. This situation forces global shipping operators to treat both the Strait of Hormuz and the Bab El Mandeb corridor as contested areas, increasing the risk and cost of every transit.

What we don't know yet

  • Will diplomatic efforts successfully establish a temporary shipping corridor that mitigates the risk?
  • How will the ongoing geopolitical realignment in the Gulf affect global energy supply chains?

What would change this answer

A formal agreement is reached between Iran and Oman to designate a safe temporary shipping routeThe immediate risk to maritime traffic could decrease, potentially stabilizing insurance premiums and easing supply concerns.
The IRGC escalates military actions or closes the strait entirelyThe disruption would become more severe, leading to a sharp increase in energy prices and greater economic strain on Europe.
