Key Highlights

  • Seaborne crude imports fell to 6.78 million barrels per day in late May, the lowest level in nearly a decade.
  • Independent refiners cut operating rates as refining margins weakened and fuel demand slowed.
  • China’s retreat from the global crude market is rewriting the script for the next oil rally.

China’s retreat from the global crude market is rewriting the script for the next oil rally. After drawing 41 million barrels from inventories in June, one of the largest monthly stockpile reductions on record, the world’s top importer has left Middle Eastern producers scrambling to place cargoes. Seaborne imports plunged to 6.78 million barrels per day in late May, the lowest level in nearly a decade, as independent refiners slashed runs and delayed purchases.

Record Inventory Drawdown Alters Supply Dynamics

China’s crude stockpiles have become the unexpected swing factor in global oil markets. The 41 million-barrel draw in June, combined with a 15 million-barrel decline in refinery inventories, offset the country’s reduced imports without triggering an immediate price spike. Analysts estimate refiners still held over 300 million barrels in storage by May, enough to cover 60-75 days of operations without new purchases.

The drawdown coincided with a sharp drop in seaborne imports, which averaged just 6.7 million barrels per day in May, 4.4 million barrels below the first-quarter average.

Teapot Refiners Cut Runs as Margins Squeeze

Independent refiners, known as "teapot" plants, have led the slowdown, cutting operating rates as refining margins collapsed. The shift followed a surge in crude prices earlier in 2025, which eroded profitability for plants already grappling with sluggish fuel demand. Many refiners pivoted to discounted Gulf grades, delaying or canceling Iranian cargoes, leaving millions of barrels of Iranian crude floating offshore without immediate buyers.

The teapot refiners’ retreat has created a feedback loop, where lower runs reduce crude purchases, further pressuring prices.

Middle East Producers Face New Competition

The drop in Chinese demand has forced Middle Eastern producers to adapt quickly. Producers have responded by offering deeper discounts, with Arab Light’s price for August-loading cargoes falling to just $1.50 above benchmark levels. The shift has also disrupted Iranian supply chains, as delayed cargoes accumulate in floating storage.

Meanwhile, China’s state-owned refiners have continued buying for strategic reserves, purchasing roughly 900,000 barrels per day for storage when prices softened. The divergence between commercial and strategic buying has created a two-tier market, where physical crude flows no longer align with traditional price drivers.

Next Rally Hinges on China’s Demand Rebound

The next oil rally may depend on whether China’s refiners return to the market. With inventories still ample, a sustained rebound in runs would signal a shift from destocking to restocking, potentially tightening global supplies. Analysts are watching for a recovery in refining margins, which could prompt teapot plants to ramp up operations.

If demand revives, the 300 million barrels held in refinery storage could become a source of incremental buying, rather than a buffer against further declines. The August pricing window for Arab Light, now at a $1.50 premium, will serve as an early test of whether discounts have stabilized or if deeper cuts are needed to lure buyers back. Until then, the market’s focus has shifted decisively from Middle Eastern geopolitics to China’s demand signals.
