**Summary**: The US has imposed sanctions on Cuba’s state energy company CUPET under a Trump executive order. While Cuba is a small crude player, sanctions could disrupt regional refined product and fuel oil flows, marginally tightening Caribbean and Latin American product markets and increasing freight and insurance premia on Cuba-linked trades.

## Detail

The key new development is that the US has sanctioned Cuba’s state oil company Unión Cuba-Petróleo (CUPET), per report [31]. The measure, announced by Secretary of State Marco Rubio under an executive order from President Trump, targets the core entity responsible for Cuba’s crude imports, refining, and product distribution. Details such as scope (full SDN designation vs narrower measures) and carve-outs (e.g., humanitarian, time-limited wind-down) are not yet specified, but the clear intent is to constrain revenue flows to the Cuban state.

From a pure volume perspective, CUPET is not material to global crude balances: Cuba imports on the order of 40–60 kb/d of crude and products, primarily from Venezuela and some spot flows. However, sanctions could have several second-order effects:

1) Regional refined product flows: Non-US traders and shipowners (especially in Europe and Asia) may reduce or cease dealings with CUPET to avoid secondary sanctions risk. This could disrupt existing product supply chains (gasoline, diesel, fuel oil) into Cuba and prompt rerouting of some Venezuelan volumes. The immediate effect is localized tightness in Caribbean product availability and higher risk premia on trades that transit near or involve Cuban ports.

2) Shipping and insurance: Vessels that have called at Cuban ports or carried cargoes for CUPET could face higher compliance scrutiny, translating into higher insurance premiums and potentially lower vessel availability for other regional routes in the short term.

3) Political signaling: This move signals a more aggressive US sanctions posture in the Western Hemisphere’s energy sphere (Cuba/Venezuela nexus). Markets may start to price a slightly higher probability of future tightening on Venezuelan barrels or shipping networks involved in sanction-evasion trades, which can marginally support heavy sour crude and fuel oil cracks.

Historical precedent: Prior tightening of US sanctions on PDVSA and on shipping firms moving Venezuelan crude produced transient but noticeable dislocations in Atlantic Basin heavy crude and fuel oil markets, supporting spreads and freight in the region.

Market impact is likely modest but potentially >1% on some niche exposures: regional Caribbean/LatAm refined product spreads, freight rates on Cuba- and Venezuela-linked routes, and possibly heavy sour benchmarks if traders extrapolate to wider sanctions risk. The impact is likely medium-lived (months) and more structural if Washington continues to escalate measures tied to Cuba/Venezuela energy trade.
