[Market Update] Crude and diesel futures move lower following reports that the Trump administration is preparing a plan to ban exports of diesel for 90 days; dollar strength continues after the report

The mechanics are straightforward if enacted: the US is a structural exporter of diesel, chiefly to Latin America and Europe, so a ban would force barrels back into the domestic market, pressuring US Gulf Coast product prices and crack spreads while tightening the Atlantic Basin balance and supporting European diesel cracks and refinery margins. The sell-off in crude alongside diesel is the standard initial read, on the view that backed-up product ultimately backs up refinery runs and crude demand, though in past episodes of export curbs the cleaner expression has been in the product and regional spreads rather than flat price. The dollar's continued strength alongside the reports fits the familiar pattern in which policy shocks of this kind are read through a risk and trade channel, though at this stage causality is difficult to separate. The tells that matter are whether the plan carries actual authority behind it, its legal basis, and whether refining and shipping interests begin lobbying visibly against it, since comparable proposals have historically been watered down or dropped under industry and trading-partner pressure. As a reported plan rather than a signed measure, the headline carries more option value than certainty.
