Government to Review Planned Fuel Duty Rise as Iran War Causes Price Surge at Pumps

Why It Matters

The decision will affect household fuel costs and the Treasury’s fiscal balance while highlighting the tension between inflationary pressures and long‑term revenue loss from the EV transition.

Key Takeaways

• Iran conflict pushes crude price to $90 per barrel.
• UK petrol up 6p, diesel up 12p in one week.
• Government reviews September fuel duty freeze removal.
• OBR projects up to £26bn revenue by 2028‑29.
• Fuel duty share could fall to 0.1% by 2050.

Pulse Analysis

The sudden escalation of hostilities in Iran has reverberated through global oil markets, lifting Brent crude to roughly $90 a barrel. That spike translates directly to UK pump prices, where motorists have seen the steepest weekly diesel increase in nearly two years. Policymakers, already grappling with post‑Ukraine price volatility, now face a fresh geopolitical shock that tests the resilience of the country’s fuel‑tax framework.

From a fiscal perspective, the planned removal of the fuel‑duty freeze was designed to replenish the Treasury as the RPI‑linked levy climbs toward 57.95p per litre. The Office for Budget Responsibility projects that this step could deliver as much as £26bn in additional revenue by the 2028‑29 fiscal year, offsetting broader budget pressures. However, the same analysis warns of a looming fiscal risk: as electric‑vehicle (EV) penetration rises, fuel‑duty receipts are expected to shrink dramatically, potentially dropping from 0.7% of GDP today to just 0.1% by 2050.

Politically, the review underscores the government’s balancing act between curbing inflation for consumers and securing long‑term fiscal health. While a full reversal of the duty increase remains uncertain, the move signals a willingness to adapt policy in response to external shocks. For motorists, the immediate concern is price stability, whereas for investors and industry observers, the evolving stance on fuel taxation offers insight into the UK’s broader energy transition strategy and its impact on public finances.
