US Gulf Coast Tanker Availability Plummets Amid Middle East Supply Disruption

US Gulf Coast Tanker Market Tightens

Oil tanker availability along the U.S. Gulf Coast has dropped sharply in recent weeks, as Asian and European refiners cut off from Middle Eastern supply have been snapping up vessels to import oil and fuel from the United States, shipping analysts and traders said.

Geopolitical Context

The Iran war has stalled tanker movements through the Strait of Hormuz, curbing the flow of Middle Eastern oil to Asia and Europe. This disruption is prompting refiners there to buy replacement barrels from the United States, Brazil and West Africa. Wider discounts on U.S. crude oil compared to global benchmark Brent crude have spurred demand for tankers in the U.S. Gulf Coast, reducing vessel availability in the region.

U.S. West Texas Intermediate crude futures for June delivery were trading at an over $10 discount to June Brent futures on Wednesday.

Unprecedented Freight Rates

The resulting surge in freight rates is unprecedented, with Suezmaxes and Aframaxes earning upwards of $300,000, compared to an average $60,000 over the past five months," Alafouzos said.

Skyrocketing freight rates increase the cost of moving oil and fuel around the world, which analysts fear could hit economic activity as the prices get passed on to consumers via the cost of everyday goods.

Vessel Availability Data

Net vessel availability along the U.S. Gulf Coast has declined 41% over the past month, according to data from The Signal Group, a shipping analytics platform. Availability of Very Large Crude Carriers (VLCC), which can carry around 2 million barrels of crude, halved to 10 vessels as of last week, from 20 on March 1.

Smaller Suezmax and Aframax vessels have also been in tight supply. Since the end of January, Suezmax tanker availability along the U.S. Gulf Coast has dropped by roughly 40-45%, while Aframax supply has dropped around 70% from a mid-February peak, said Maria Bertzeletou, senior market analyst at The Signal Group.

Trade Routes and Destinations

The tightness has coincided with increased fixture activity on the U.S. Gulf Coast to Asia route. At least 10 vessels have been fixed to haul oil or fuel from the U.S. Gulf Coast to Asian markets over the last seven days, destined mainly for Pakistan, Korea and South China.

Analyst Commentary

The movement of cargoes from the West to the East, starting with VLCCs to Asia and then smaller sizes catering to European demand, gave birth to an unprecedented surge in freight rates," said Matias Togni, oil and shipping analyst at NextBarrel.

Market Context

This market shift is driven by a confluence of geopolitical tension and economic incentives. The conflict in the Middle East has physically restricted supply routes, while price differentials make U.S. crude attractive to importers who can no longer access traditional sources efficiently.

Key Takeaway

The combination of war-induced supply disruptions and significant pricing discounts on U.S. oil has created a severe shortage of tankers along the Gulf Coast, driving freight rates to record highs and raising concerns about broader economic impacts through consumer goods.
