U.S. oil and gas executives expect diesel prices to remain elevated for more than a year, according to the latest Federal Reserve Bank of Dallas survey of 100 companies. Forty-eight percent said diesel prices could take more than four quarters to return to 2025 levels, compared with 36% for gasoline. The survey linked the prolonged fuel crisis to the Iran war and Ukraine's attacks on Russian refining facilities. AAA said the average U.S. diesel price was $6.4139 per gallon on Wednesday, about 73% higher than a year earlier. President Donald Trump has been considering a diesel export ban, while the White House has coordinated with European allies, urged countries to release strategic reserves and discussed increased Chinese refinery production.
