Key Points
G7 releases 100 million barrels of diesel over four months starting immediately October 2.
UK diesel prices hit record £2 per litre, threatening coach and haulage services.
Trump threatened export ban to lower US prices, forcing Europe to tap emergency reserves.
WTI crude fell $1.76 to $91.11 but oil markets remain volatile amid Iran war tensions.
The G7 announced on October 2 a coordinated release of 100 million barrels of oil and diesel to stabilize global energy markets after US President Trump threatened to ban diesel exports. A substantial diesel release will occur within 20 days, with the full programme running four months. The move follows record UK diesel prices exceeding £2 per litre, pushing hundreds of transport firms toward closure and forcing cuts to school coach services.
Why diesel prices hit record highs in the UK
UK diesel forecourt prices topped £2 per litre last week, the highest on record. The surge stems from the Iran war disrupting Middle Eastern fuel exports and reducing supplies from Russia, Saudi Arabia, and the UAE. Europe relies heavily on US diesel imports, leaving the continent vulnerable to supply shocks and price spikes as winter approaches.
Trump’s export ban threat forced Europe’s hand
US President Trump warned he would ban diesel exports unless European nations released emergency fuel stocks. The threat prompted G7 leaders to agree on October 2 to release 100 million barrels coordinated through the International Energy Agency. Trump later said the export ban was “never really on the table”, but the pressure worked: Europe tapped its reserves to avoid economic damage heading into winter.
UK transport sector faces collapse without relief
Coach operators warn record diesel costs could force cuts to school transport and other services. Alison Edwards, director of policy at the Confederation of Passenger Transport, said fuel costs have “surged to unsustainable levels, pushing operators’ tight margins to breaking point.” Hauliers report paying an extra £350 per week per truck compared with before the Iran war. Richard Smith of the Road Haulage Association said 2% profit margins mean “hundreds of transport businesses” have already gone bust this year.
Oil prices dip but recovery risks remain
WTI crude fell $1.76 to $91.11 per barrel and Brent dropped 6 cents to $102.25 on October 5 after the G7 announcement. Heating oil settled down 14.09 cents at $4.5011. However, the market remains volatile: oil bounced back above $102 within hours as traders weighed the reserve release against continued Middle East tensions and the lack of progress toward ending the Iran war.
Final Thoughts
The G7 diesel release offers short-term relief but cannot solve Europe’s structural energy crisis. UK transport operators need government support beyond the reserve release, or service cuts and business failures will accelerate into winter.
FAQs
The release began immediately on October 2 and will run for four months. A substantial diesel portion will be front-loaded within the first 20 days.
Trump wanted to lower US diesel and gasoline prices ahead of November’s midterm elections by keeping more fuel domestic for American consumers and farmers.
UK diesel hit a record price of more than £2 per litre last week, up sharply due to the Iran war disrupting Middle Eastern supplies.
Operators warn school transport services will be cut and hundreds more transport businesses will go bust, as 2% profit margins cannot absorb record fuel costs.
