Japanese refiners Eneos Holdings and Idemitsu Kosan have broken with convention by purchasing Middle Eastern crude for October loading a full month ahead of schedule, pushing spot premiums in the Persian Gulf to $38 per barrel. This unprecedented move comes in the wake of last week's attack that shut down Saudi Arabia's vital East-West pipeline. The rush to secure supply has created acute tightness in prompt cargoes, dramatically raising procurement costs for Asian buyers.
According to trading sources, Eneos Holdings and Idemitsu Kosan recently purchased Omani crude with the earliest loading dates in October. Under normal trading patterns, Persian Gulf cargoes bought in September would typically be loaded in November—meaning these purchases were secured a full month earlier than usual. Two cargoes of 2 million barrels each were transacted at premiums of $38 per barrel over the Dubai benchmark, with sellers including trading houses and oil majors. Both companies declined to comment on the deals.
The buying spree extends beyond Japan. Chinese refiners Shandong Dongming Petrochemical and Shenghong Group have recently purchased Middle Eastern crude for October and November delivery, while Indian state-owned oil companies have also booked October-loading cargoes through tenders. This concentrated release of Asian demand has driven Persian Gulf spot premiums sharply higher.
Where to begin understanding the buying frenzy
The scramble for crude stems directly from last week's attack on Saudi Arabia's East-West pipeline—a 1,200-kilometer artery spanning the Arabian Peninsula that serves as the critical alternative route bypassing the Strait of Hormuz to deliver oil to the Red Sea port of Yanbu. With the pipeline out of commission, Yanbu's storage can sustain only five to seven days of export demand, and repair estimates range from several days to five or six weeks. The disruption threatens approximately 4 million barrels per day, representing nearly 4% of global supply, prompting Saudi Aramco to delay deliveries to some European customers.
The two 200,000-barrel Omani cargoes secured at $38-per-barrel premiums over Dubai benchmark reflect scarcity pricing for prompt supply that far exceeds normal levels. Amid the supply disruption, Saudi Arabia has redirected export flows from Yanbu back to eastern ports, causing Red Sea exports to drop by 4.5 million barrels per day in August compared to July. This has slashed the availability of immediately sellable cargoes, forcing buyers to pay higher premiums in exchange for certainty on loading schedules.
Why just 10 Asian refiners are driving this shift
For Japanese refiners, the challenge is compounded by Asian buyers simultaneously entering the prompt market, creating competition that necessitates even higher premiums to secure cargoes. This dynamic is pushing procurement costs substantially upward across the region. The synchronized entry of multiple Asian buyers underscores how dependent the region remains on Middle Eastern supply despite efforts to diversify.
The implications extend beyond immediate procurement. If Persian Gulf premiums remain elevated, early cargo locking by Asian buyers could evolve from isolated incidents into an established trend. Market participants are now closely monitoring repair progress on Saudi Arabia's East-West pipeline and whether spot premiums can retreat as supply normalizes. The coming weeks will be critical in determining whether this pricing pressure is temporary disruption or signals a structural shift in how Asian refiners approach their procurement calendars.
