UK petrol and diesel prices are going up again as the price of oil returns to around $100 a barrel.

UK petrol prices have risen their highest level since mid-June, according to data from motoring organisation RAC, as the US-Israel war with Iran continues to affect drivers' finances. The price of fuel tends to track the wholesale price of oil and both have been rising for weeks since the collapse of peace talks to end the conflict. When the conflict began on 28 February, prices surged as the fighting severely disrupted the production and transportation of energy across the Middle East. Prices then nosedived when US and Iran agreed to a framework deal to end the fighting in June, but wholesale oil has risen above $100 (£75) a barrel again as tensions resurface. Simon Williams, head of policy at the RAC, said: "Unless the hostilities end soon, it's hard not to see the price of petrol reaching a new Iran war high." Crude oil is a key ingredient in petrol and diesel, which means that higher wholesale costs make filling up a car more expensive. Analysts say every $10 (£7.53) increase in the oil price pushes up pump prices by roughly 7p a litre. Since the war began, the price of a barrel of Brent crude – the global benchmark for wholesale oil prices – has been very volatile.
