US Diesel Export Ban Could Raise Gasoline Prices, Morgan Stanley Warns

In brief

  • Morgan Stanley warns diesel export ban could tighten fuel supply and raise gasoline prices
  • US diesel prices hit record $6.51 per gallon; gasoline around $4.48
  • Prediction markets price crude oil reaching all-time high by year-end at 10.5%

Refinery Pressure and Supply Dynamics

Diesel prices in the US are already elevated. They averaged $6.5107 per gallon, a record high, while gasoline prices hovered around $4.48 per gallon. A ban on diesel exports would restrict refiners' ability to sell surplus fuel abroad, potentially forcing them to cut production. That reduction in throughput cascades across both fuel markets.

Morgan Stanley's commentary aligns with broader industry views. While restricting diesel exports might offer short-term relief in domestic diesel prices, it could inadvertently push up overall fuel prices by reducing refinery activity. Refineries operate at optimal efficiency when they run at full capacity. Lower throughput means higher per-unit production costs, which get passed to consumers at the pump.

Market Sentiment Shifts

Prediction markets reflected growing concern, pricing the likelihood of crude oil reaching a new all-time high by December 31 at 10.5%. This marked a slight increase from 10% the previous day, suggesting traders are taking the export-ban scenario more seriously. Each incremental shift in these odds reflects traders' updated assessment of policy risk and its downstream effects on crude supply and pricing.
