Trump's Jones Act Waiver Fails to Boost Domestic Oil Flows

What happened

In March, President Trump suspended Jones Act rules for 60 days, allowing foreign-flagged ships to transport fuel between U.S. ports. The policy aimed to lower domestic fuel prices by increasing shipments from Gulf Coast refineries to markets like California and Hawaii that lack pipeline connections. However, shipping data shows crude oil and refined product movements between U.S. ports remained virtually unchanged at about 1.37 million barrels per day in March. Shipments from the Gulf Coast to other U.S. coastal markets actually declined from 826,000 barrels per day in February to 770,000 barrels per day in March.

Why the stock moved

U.S. refinery stocks have benefited as Gulf Coast refiners choose to maximize international sales rather than domestic shipments. Major independent refiners like Marathon Petroleum, Phillips 66, Valero Energy, and PBF Energy are positioned at the origin of export infrastructure and marine terminals. Following Iran's blockade of the Strait of Hormuz, Asian and European refiners have cut production due to crude shortages, creating strong demand for U.S. fuel exports. U.S. refined products exports hit a record in March, and refining margins surged sharply after recent quarters pressured by global oversupply. The spread between U.S. ultra-low sulfur diesel futures and West Texas Intermediate crude futures widened to over $72 per barrel, compared to about $40 before the Iran conflict.

Bigger picture

The Iran war has fundamentally reshaped global fuel markets, creating scarcity in regions dependent on Middle Eastern crude while U.S. refiners remain largely unaffected. Gulf Coast refinery utilization climbed to above 95% in March, compared to around 90% a year earlier and a five-year seasonal average of about 82%. Meanwhile, Asian refinery utilization has dropped to the low-to-mid 80% range after run cuts. U.S. refiners face a clear economic incentive to export: European gasoil futures traded above $200 per barrel compared to U.S. diesel futures below $185. Additionally, Asian refiners bidding up vessels to import U.S. crude has tightened the Gulf Coast tanker market and sent freight rates soaring, making longer international voyages more profitable for ship owners than domestic routes.

What investors watch

The key question is whether the fragile two-week ceasefire between the U.S. and Iran will hold and whether the Strait of Hormuz reopens to meaningful tanker traffic. If Middle Eastern crude flows resume, the premium U.S. refiners earn on exports could narrow significantly. Investors should also monitor domestic fuel prices, which continue trending toward record highs as refiners prioritize international sales. Refinery utilization rates and export volumes will indicate whether these elevated margins persist. The Jones Act waiver expires in mid-May, though its impact has proven minimal compared to global market dynamics.
