A potential US ban on diesel exports could push inflation in the United Kingdom close to 5%, economists have warned, as the country faces record-high diesel prices and tightening global fuel supplies.The warning comes after UK diesel prices crossed £2 per litre for the first time. Economists at Capital Economics estimate that a full US diesel export ban could push UK diesel prices towards £3 per litre and add around one percentage point to inflation.Key HighlightsUK diesel prices have crossed £2 per litre.A full US diesel export ban could push diesel prices towards £3 per litre, according to Capital Economics.Economists estimate the move could add around 1 percentage point to UK inflation.The UK relies heavily on imported diesel.G7 countries have agreed to release emergency oil and diesel stocks to ease supply pressures.The impact of a US export ban remains uncertain as alternative supplies could offset some of the shortage.US Diesel Export Ban Raises UK Inflation ConcernsUS President Donald Trump has been considering restrictions on diesel exports as American fuel prices rise. Reports indicate that the US has also urged European countries to release emergency diesel stocks to help ease pressure on global supplies.For the UK, any reduction in US diesel exports could create additional competition for alternative supplies. Britain imports around half of the diesel it consumes, making international fuel markets particularly important for domestic prices.Capital Economics chief UK economist Paul Dales estimated that a complete US export ban could raise UK diesel prices from around £2 to approximately £3 per litre. Such an increase could add about one percentage point to inflation, potentially taking the inflation rate to around 5.3%.UK Diesel Prices Hit Record HighThe warning comes as diesel prices in Britain have already reached record levels. The average UK diesel price climbed above £2 per litre, with the RAC reporting an average of around 200 pence per litre.The rise has been linked to disruptions in global oil and refined-fuel supplies amid conflicts affecting the Middle East and Ukraine. The UK has also faced restrictions and uncertainty around supplies passing through the Strait of Hormuz and reduced Russian exports.Higher diesel costs can affect more than motorists. Diesel is widely used in road transport, agriculture, construction and logistics, meaning sustained price increases can feed into the cost of moving goods and eventually consumer prices.G7 Moves to Release Emergency Fuel StocksThe potential US export restrictions have also prompted action from major economies. G7 countries have agreed to release up to 100 million barrels of oil and diesel from emergency reserves over four months, with a substantial amount of diesel expected to be released early in the programme.The measure is intended to increase fuel availability and ease pressure on global markets. However, analysts have cautioned that the longer-term direction of prices will also depend on developments in the conflicts disrupting oil supplies.UK Government Says Diesel Supply Is DiverseUK officials have sought to reassure consumers that the country has a diverse range of diesel suppliers. Transport Minister Keir Mather said the UK has a resilient supply network while the government continues discussions with international partners.The UK has also joined emergency talks with European partners following the US threat of export restrictions.The potential inflation impact therefore depends on whether alternative diesel supplies and emergency stock releases can compensate for any reduction in US exports. The estimate of inflation reaching around 5% is an economic projection rather than a confirmed outcome.
