Oil Surges Past $100 Per Barrel Amid Middle East Tensions, Driving Up Fuel Prices

Fuel prices are experiencing a sharp increase as oil prices have surpassed $100 a barrel for the first time since late May, driven by escalating hostilities in the Middle East. The average price for a litre of petrol in the UK has risen by 5 pence in the last two-and-a-half weeks, reaching 155.57 pence, while diesel has climbed nearly 8 pence to 172.14 pence over the same fortnight.

This surge has added approximately £3 to the cost of filling a 55-litre unleaded petrol tank and over £4 for a comparable diesel tank. The increase in pump prices is directly linked to the soaring cost of crude oil, which began to climb after the resumption of conflict between the United States and Iran earlier this month.

Brent crude, an international benchmark for oil, crossed the $100 per barrel mark on July 23, 2026. Analysts caution that further price rises are likely following attacks by Iran-backed Houthi militants on two oil tankers near the Red Sea. This incident risks creating a second major chokepoint for global oil supplies, compounding concerns over the Strait of Hormuz.

Simon Williams, head of policy at motoring group RAC, described the situation as "fuel prices shooting up like a rocket." He noted that recent price reductions are being reversed, with unleaded petrol heading towards 160 pence per litre and diesel towards 180 pence per litre. If petrol prices reach 160 pence, they would exceed the previous high of 159.53 pence seen on May 28, attributed to the "Iran war." Williams warned that UK drivers could face "stinging summertime pump prices" if the conflict is not resolved quickly.

The oil price has seen five consecutive days of increases, coinciding with the widening scope of the conflict. The Houthi attacks on Saudi oil tankers in the Bab el-Mandeb Strait, a key waterway, have exacerbated supply disruption concerns. Previously, the conflict had primarily threatened supply through the Strait of Hormuz.

Analysts at Goldman Sachs predict that Brent crude could reach $120 per barrel in the fourth quarter and average $100 next year if the Strait of Hormuz remains under threat. Persistent issues in the Bab el-Mandeb Strait could lead to even higher prices. The oil market has experienced volatility since the beginning of the "Iran war" in late February, with prices jumping from $72 to a peak of $126 in April before declining to $70 by early July. The collapse of a fragile peace deal has since triggered a sharp upward spiral.

Jonathan Raymond, investment manager at Quilter Cheviot, stated that the renewed Middle East hostilities are forcing a reevaluation of oil supply and demand dynamics, pushing prices to $100 per barrel. He highlighted the immediate impact on households through higher petrol and diesel prices, with the potential for increased energy bills in the coming months. The ripple effect of more expensive fuel and energy could extend to increased costs for businesses, ultimately affecting the price of food and other goods.
