WASHINGTON, D.C. — Diesel in the United Kingdom has broken the £2‑a‑litre barrier for the first time, with the RAC reporting an average price of £2.01 per litre on Monday, a development driven by soaring global crude oil markets and domestic tax pressures.

The RAC’s latest fuel price survey shows diesel at £2.01 per litre, up 8.4 % from a month ago, while regular unleaded petrol rose to £1.85 per litre, a 7.9 % increase. Brent crude, the global benchmark, settled at $90.70 a barrel on Friday, its highest level in six weeks, amplifying cost pressures for refiners and distributors across Europe.

KEY POINTThe RAC’s latest fuel price survey shows diesel at £2.

Transport Secretary Mark Harper warned that the rise reflects “the inevitable pass‑through of higher wholesale costs and the current fuel duty structure.” The UK’s fuel duty of 57.95 pence per litre, combined with a 17.5 pence per litre carbon levy, adds to the headline price, prompting calls in Parliament for a temporary relief measure.

Analysts at Barclays note that the sustained price surge could sharpen investor focus on the UK’s oil and gas sector, where upstream firms stand to benefit from higher margins, while downstream retailers may see profit compression. “Investors will be weighing the upside of higher crude against the risk of reduced demand as consumers curb mileage,” said senior energy analyst Sarah Patel.

Consumer groups such as Which? predict a measurable dip in road travel, with a recent survey indicating that 42 % of drivers plan to reduce non‑essential journeys over the next month. The shift may accelerate demand for electric vehicles, a sector that has already seen a 12 % rise in registrations since the start of the year.

Key Takeaways

• UK diesel price hits £2.01 per litre, the first time crossing the £2 mark.
• Global Brent crude climbs to $90.70 a barrel, fueling domestic price increases.
• Higher fuel costs could influence investor sentiment, consumer behaviour and policy debates on fuel duty.

As the UK grapples with record‑high pump prices, policymakers, investors and motorists alike will monitor the interplay between global oil markets, fiscal measures and the accelerating transition to greener transport solutions.
