Diesel Prices See Record Drop in June Amid Easing Iran Tensions

Diesel prices in the UK experienced a record-breaking drop of 16.6 pence per litre in June, marking the most substantial monthly decrease since records began in 2000. This significant reduction at the pump is attributed to a sharp fall in oil prices, which in turn was influenced by easing tensions between the United States and Iran.

Brent crude, the international benchmark for oil, saw its price slide from $93 a barrel to $73 over the 30-day period. This decline in crude oil costs has been directly reflected in the prices drivers pay at the forecourt. At the start of June, the average price for a litre of diesel in the UK stood at 183.75 pence. By the end of the month, this had fallen to 167.14 pence.

This decrease translates to considerable savings for vehicle owners. Drivers of a typical family car with a 55-litre fuel tank would have saved approximately £9, with the cost to fill up dropping from around £101 to just under £92. The reduction in diesel prices was even more pronounced at the pumps of major supermarkets, where the average price per litre fell by 19 pence, from 182.37 pence to 163.28 pence.

Petrol prices also saw a decrease in June, falling by 8 pence per litre. This was the seventh-largest monthly drop recorded over the past 26 and a half years, with the average price declining from 159.37 pence to 151.40 pence. This change resulted in savings of about £4.40 per tank for petrol car owners.

Despite these welcome reductions, the head of policy at the RAC, Simon Williams, noted that drivers are still paying more for fuel than they were prior to the conflict in the Middle East. He pointed out that diesel prices had risen by 49 pence per litre between late February and mid-April, averaging an increase of more than one penny per day. He added that further price drops are anticipated, contingent on continued lower oil prices. Currently, oil is trading in the low $70s per barrel, which is only $10 above the average price seen in the first two months of the year. To return to pre-conflict price levels, when unleaded petrol averaged 132 pence and diesel averaged 142 pence, oil prices would need to decrease further. Currently, petrol is expected to fall below 150 pence per litre soon, and diesel is projected to drop below 160 pence per litre.
