Petronas Ships Fuel Oil to U.S. West Coast in First Such Run in Three Years
A 540,000-barrel LSSR cargo from Malaysia's PRefChem plant shows how Hormuz-driven feedstock scarcity is forcing Pacific Rim refiners to seek supply further afield.
The Solomon Sea tanker, laden with more than 540,000 barrels of low-sulfur and straight-run fuel oil, left Malaysia's PRefChem refinery, operated by state oil giant Petronas, during the week of 2026-08-03 bound for a U.S. West Coast refinery, MarineTraffic data showed. It is the first cargo of this type on that route in three years.5
The shipment is a direct consequence of feedstock markets tightening sharply since the Strait of Hormuz closed on February 28, 2026. Middle East production shut-ins reached 10.5 million barrels per day in April and were forecast to peak near 10.8 million bpd in May, OGJ analysis showed, stripping buyers across Asia and the Pacific of supply they had long treated as reliable.1,5
Low-sulfur and straight-run fuel oil is a refinery feedstock, not a finished product. Tighter supply curbs throughput directly. West Coast U.S. refineries, geographically isolated from Gulf Coast and Atlantic Basin alternatives, have narrower options when Pacific supply falls short. When domestic and nearby sources dry up, a transoceanic voyage from Malaysia to California becomes preferable to cutting runs.5
The scale of the Middle East disruption puts this in context. In 2025, the United States imported an average of 490,000 barrels per day from the Middle East Gulf region, concentrated in medium-sour grades, EIA data published in April 2026 showed. That flow has been heavily disrupted since the Hormuz closure, leaving West Coast refiners, already running on constrained feedstock slates, particularly exposed.4
The broader crude market has rebalanced fast but unevenly. U.S. crude exports reached 5.15 million bpd in April, up 1.22 million bpd from March, as Asian and European buyers sought barrels outside the Middle East, Kpler data showed. OGJ forecast U.S. crude production at 13.65 million bpd for full-year 2026, up 0.5% from 2025. But expanded export capacity does not automatically solve the sulfur content and density specifications that govern which streams West Coast refinery configurations can process.1
Across Asia, competition for feedstock has intensified simultaneously. Indian refiners imported 5.27 million bpd in May, up 15.4% from April, industry data showed, with Russia supplying about 1.92 million bpd, or roughly 36.5% of total Indian imports, up from 35% in April. The UAE became India's second-largest supplier, with imports rising nearly 41% to 942,500 bpd in May, boosted by supply from Fujairah following the Gulf producer's exit from OPEC. As those buyers locked in volumes, competition for other feedstock streams, including Malaysian LSSR, stiffened.3
U.S. refiners have also been running hard on finished product demand. Jet fuel production climbed to record highs following the Hormuz closure, EIA weekly estimates showed, as Asia and Europe, previously large importers of Gulf jet fuel, scrambled for alternative supply. That production surge absorbed domestic crude and feedstock, compounding pressure on West Coast plants already struggling to secure input barrels.2
ICE Brent crude front-month sat at $91.55 a barrel and NYMEX WTI front-month at $84.54 a barrel as of 2026-08-19. Those levels make long-haul feedstock procurement expensive. But when Pacific supply is short and refinery throughput is at stake, freight cost gets subordinated to feedstock availability. [Live prices]
PRefChem is a modern, export-oriented facility, and a successful delivery could establish a trade lane dormant since before the Hormuz disruption. Whether a second cargo follows will depend on the specification match the receiving West Coast refinery reports, the freight economics once the voyage completes, and how quickly Middle East supply routes recover. The Solomon Sea is still at sea.5
