US Diesel Ban Could Spark UK Inflation Spikes to 5% Amid Record Fuel Prices

Economists are sounding the alarm over the potential impact of a US diesel ban on UK inflation. If President Donald Trump were to stop exports of diesel, forecasters warn that prices could surge to £3 per liter and push up inflation by as much as one percentage point.

This would come on top of other supply shocks, further strengthening the case for Bank of England interest-rate hikes. The warning comes after motorists saw diesel prices hit a record high of £2 ($2.7) per liter for the first time ever in October 2026.

The predicted inflation spike is based on a prolonged ban, which would lead to higher fuel costs and increased pressure on household budgets.
