## Prediction

Over the next 7 days, as Mexico operationalizes its crude trade strategy with Cuba, traders will modestly price in higher compliance and sanctions risk on Mexican and some broader Latin American barrels moving through the Gulf-Caribbean corridor. US Gulf refiners may preemptively diversify feedstock sourcing to avoid future complications, while some independent traders exploit arbitrage opportunities. The overall volume impact will remain small, but the perceived risk premium on Maya and similar grades could widen slightly relative to benchmark. Confirmation would be adjusted discounts/premia for Mexican crude and new compliance guidance from US or EU authorities; denial would be fully symbolic Mexico–Cuba engagement with no actual cargoes moved.

## Drivers

- Mexican announcement of a new oil commerce strategy with Cuba
- US sanctions framework on Cuba and secondary-sanctions risk
- Existing sensitivity of refiners and traders to compliance costs
