US diesel rises 1.21% as traders weigh Trump export curbs

The headline risk here is policy, not supply: prices are moving on the mere possibility of export curbs, which suggests the market is pricing uncertainty rather than a confirmed change in trade flows. That distinction matters because fuel exports sit at the intersection of domestic inflation politics and global refining balances, so any restriction would be felt well beyond US borders. The open question is whether this stays a positioning story or hardens into actual policy — and whether the administration clarifies timing or scope.
