Trump Weighs Easing Shadow Fleet Sanctions to Lower Oil Shipping Costs

The “shadow fleet” refers here to tankers already under sanctions. The article does not provide a formal definition, but it describes these vessels as restricted ships that could potentially carry other, “legitimate” fuel. Their status matters because sanctions limit which cargoes they can transport and which companies can use them.

The proposed system would exclude Russian and Iranian oil subject to sanctions. Companies wanting to use the tankers would first need authorization from the US Treasury Department. This would separate permitted fuel movements from shipments tied to sanctioned supplies.

The article does not identify every reason individual vessels were sanctioned. It links the restrictions to efforts to control oil-related revenue and prevent sanctioned countries from moving petroleum freely. Any easing would therefore be limited, conditional, and still affected by European and British rules.

The Trump administration is considering a narrow relaxation of restrictions on shadow fleet tankers. The goal is to let some sanctioned vessels transport “legitimate” fuel. The proposal matters because it could add ships to routes carrying oil from the Persian Gulf and help address high shipping costs.

The key condition is permission. Companies seeking to use the vessels would need authorization from the US Treasury Department. Even then, the tankers could not carry Russian or Iranian oil that remains subject to sanctions. The Energy Department also said the change would not help Russia transport oil or petroleum products.

This would not amount to a broad end to sanctions. European Union and UK rules would still apply, including insurance requirements. The proposal therefore offers a controlled channel for selected cargoes, while keeping major restrictions on sanctioned Russian and Iranian supplies.

The article says a small number of additional tankers could become available for short-haul trips through the Strait of Hormuz. It does not give a precise number. That limited scale is important because the proposal would not suddenly expand the entire global tanker fleet.

The vessels would remain subject to several conditions. Companies would need US Treasury authorization to use them, and their cargoes could not include sanctioned Russian or Iranian oil. Maritime sources also said insurers would still have to follow European Union and UK regulations, creating another practical barrier.

As a result, the number of usable ships would probably remain small. Reuters’ maritime sources said the change was unlikely to produce a widespread fall in freight rates. It could add some capacity on particular Persian Gulf routes, but broader shipping markets would see only a limited effect.

Allowing selected shadow fleet tankers to carry legitimate fuel could make more ships available for short-haul journeys from the Persian Gulf. More available ships can ease competition for vessels and help move fuel more efficiently. That could lower some shipping costs and support additional oil supplies reaching markets.

The mechanism would be limited. Companies would need US Treasury authorization, and the vessels could not carry sanctioned Russian or Iranian oil. Insurers would also remain bound by European Union and UK rules. These conditions would prevent the entire shadow fleet from entering ordinary fuel trades.

Maritime industry sources told Reuters that only a small number of tankers might be added. They also judged that freight rates would probably not fall widely. The likely effect is targeted: some extra capacity on Hormuz routes, rather than a major global change in oil prices or supply.

A US decision would control only the American authorization described in the proposal. Tanker operators and companies would still face rules enforced by the European Union and the UK. Those rules matter because insurers must comply with them even if Washington permits a voyage.

The practical mechanism is access to coverage. If insurers cannot legally cover a vessel or cargo, companies may avoid using that tanker, despite US approval. The article specifically says insurers would still have to comply with European Union and UK regulations, preserving an important restriction.

This means the US move could release only some shipping capacity. European and British sanctions could continue limiting available tankers, cargoes, and routes. That is why maritime sources expected only a small increase in vessels and no widespread reduction in freight rates. The decision’s effect would depend on several jurisdictions, not Washington alone.

The Strait of Hormuz matters because the proposal specifically concerns short-haul tanker trips through it from the Persian Gulf. The article connects the waterway with regional oil movements and with the wider availability of energy supplies. Keeping that route open supports the movement of fuel from Gulf producers.

The article gives a concrete warning about its importance. It says the US temporarily exempted some Russian oil shipments from sanctions in the spring amid the war in Iran and the closure of the Strait of Hormuz. That closure was described as part of broader disruptions to global energy supplies.

If more approved tankers can travel through the strait, some Persian Gulf cargoes may move more easily. However, the expected benefit remains small because only a limited number of vessels may qualify. Insurance restrictions and other sanctions would continue limiting the route’s potential effect.

Sanctions can block ships, cargoes, companies, and payments from participating in oil trade. Tanker insurance adds another gate because insurers must follow applicable rules before covering a voyage. Access to usable ships therefore affects how much oil can move, how expensive transport becomes, and how reliably buyers receive supplies.

The article gives several examples. The US proposal could make a small number of tankers available for legitimate fuel, potentially lowering some shipping costs. At the same time, Russian diesel sales were authorized through April 7, 2027. Zelensky argued that allowing Russian petroleum sales would give Moscow additional revenue to continue its war.

These measures can pull in opposite directions. More permitted shipping may support global supplies and stabilize prices, while tighter restrictions may reduce revenue available to sanctioned exporters. European, British, and US rules together determine how much of that trade actually occurs. The article expects any effect from the tanker proposal to remain limited.
