U.S. heating oil prices fell to about $4.80 a gallon from a record above $5.20 last week as the Trump administration considered limiting diesel exports to ease domestic fuel costs. President Donald Trump indicated support for an export ban, while Politico reported that officials were preparing a 90-day prohibition. Energy Secretary Chris Wright told The Wall Street Journal that the administration was considering restrictions rather than an outright ban, underscoring internal divisions over the proposal. Refining shares declined after the Politico report, while industry experts warned that curbing exports could lead refiners to reduce output, raise retail gasoline prices and trigger retaliation from U.S. trade partners. Saudi Arabia's partial restoration of its East-West pipeline has eased some supply concerns, though geopolitical risks continue to influence diesel markets.
