Why the US-Iran conflict is causing a global fuel crisis

A military confrontation involving the United States, Israel, and Iran began in February 2026, when American and Israeli forces carried out strikes that grew into an extensive combat campaign. Now in its seventh month, the hostilities have heavily disrupted oil extraction and commercial transit in the Middle East.

Tensions have also spilled beyond the primary conflict zone. Saudi Arabia reported drone damage to an electrical facility in Medina attributed to Tehran-aligned Houthis, while British counter-terrorism detectives recently detained suspects near RAF Fairford, a military airfield utilized by the United States Air Force, examining possible ties to a foreign power.

The fighting has effectively closed normal commercial passage through the Strait of Hormuz, one of the world's most vital petroleum arteries. Iraqi Prime Minister Ali al-Zaidi reported that roughly 90 percent of his nation's Gulf crude flows have been halted, creating about $60 billion in lost state revenue.

Because oil sales finance nearly all of Baghdad's national budget, the blockade has delayed public salaries and triggered protests. Iraq has tried utilizing pipeline transport to Ceyhan in Turkiye, trucking fuel north from southern fields, and using small vessels under American military protection, but these measures cannot replicate the volume usually moved through the waterway. Other Gulf producers like Qatar and Kuwait have slashed crude prices by up to $35 a barrel to attract cautious shipping customers.

Disruptions in crude extraction and refining have driven up fuel costs worldwide, particularly for diesel. In the United Kingdom, diesel surpassed £2 a litre for the first time, raising the expense of filling a typical family vehicle by £32 since hostilities began. In Northern Ireland, where over half of passenger cars rely on diesel, prices rose to 193.3p per litre.

The crisis has been exacerbated by refinery strikes inside Russia, Chinese fuel export curbs, and heavy European reliance on foreign shipments. Within the United States, surging fuel expenses have strained agriculture, trucking, construction, and municipal budgets, turning energy costs into a central issue ahead of upcoming midterm elections.

Friction emerged after US President Donald Trump raised the possibility of barring American diesel exports to shield domestic consumers, a policy European allies warned would undermine transatlantic relations. In response, G7 leaders held emergency virtual negotiations alongside the International Energy Agency.

The bloc resolved to release 100 million barrels of fuel across a four-month timeframe, emphasizing a large, front-loaded distribution of diesel during the opening 20 days. Participating nations explicitly discouraged trade barriers or export embargos that might cause additional turmoil in international energy markets.

The Pentagon is deploying roughly 9,000 additional personnel to the region, including the USS Theodore Roosevelt and USS Makin Island groups. These forces will join two carrier strike groups and an amphibious group already present, raising American strength in the theater to around 20,000 troops.

At the same time, Defense Secretary Pete Hegseth has forced out civilian service secretaries and moved to dismiss roughly 20 percent of senior military officers to overhaul the defense establishment, drawing criticism from former defense officials over leadership stability during an active war. Meanwhile, long-planned American troop withdrawals from Iraq were formally completed.

Roughly 9,000 additional American troops are scheduled to arrive in the Middle East before the end of October. G7 nations will implement their 100-million-barrel emergency reserve drawdown over the next four months, starting with an immediate 20-day release of diesel.
