Output Cuts Get Official Backing
China's powerful state planner, the NDRC, has authorized certain independent refiners to slash output beginning in June, according to consultancies and sources cited by Reuters. The move provides official cover for refiners already bleeding cash. Shandong's smaller independent operators, often called teapots, have seen processing losses on imported crude widen to around Yuan 1,397 per metric ton in May, up from Yuan 401 in April.
The timing is deliberate. Rather than forcing marginal refiners to keep running at uneconomic rates, Beijing is letting market economics do the work while it draws down inventory buffers built during the spring. State planners appear confident that current stockpiles can cover any shortfall without triggering domestic fuel crises.
Refinery Runs at Pandemic-Era Lows
The cuts follow months of declining throughput across both state and private sectors. In April, Chinese refiners processed 54.65 million tonnes of crude, down 11% from March and nearly 6% below year-ago levels. Utilization at state refineries dropped to 71.6% in May, the lowest reading since March 2020 when COVID shutdowns cratered demand. Private mega-complexes fared no better, with run rates falling nine percentage points from April to 70% in May.
Crude imports have collapsed alongside throughput. April imports came in at 9.25 million barrels per day, the lowest since July 2022. The missing cargoes were overwhelmingly Middle Eastern grades that could no longer transit the Strait of Hormuz. Independent refiners have been hit harder than state firms because they lack access to long-term supply contracts and must rely on pricier spot purchases.
Hormuz Fallout Reshapes Supply
The NDRC's decision does not exist in a vacuum. The Strait of Hormuz, which handled roughly 20% of global seaborne oil trade before the Iran conflict, has operated at around 5% of pre-war volumes since April. Tanker traffic dropped first by 70% after Iranian attacks on vessels, then collapsed to near zero as insurers pulled coverage and major shipping lines suspended transits. About 22,500 mariners remain trapped on more than 1,550 commercial vessels in the region.
For China, the math is stark. Roughly 40% of its crude imports previously transited Hormuz. Saudi Arabia has rerouted some barrels through its East-West pipeline to Yanbu on the Red Sea, but the 5 million barrel per day line cannot fully replace what flowed through the strait. Oil industry analysts told OPEC at a Vienna meeting this week that the supply disruption will persist through year-end even if shipping lanes reopen promptly.
Inventory Buffers Provide Room
Beijing's confidence rests on domestic stockpiles. As of late May, gasoline inventories stood at 85.95 million barrels and gasoil at 99.76 million barrels, representing around 25 days of demand coverage. These levels are slightly above year-ago figures despite the throughput cuts, a function of soft consumption and tight export restrictions on refined products.
State refiners have been drawing on crude inventories built in previous months. One South China refinery source told S&P Global Platts they have reduced crude purchases or resold June cargoes to avoid inventory devaluation on interim financials, a hedge against further price declines if the Middle East situation deteriorates. Another state refiner plans to idle a 100,000 barrel per day plant in June while running its other 200,000 barrel per day facility at 88% capacity.
Margins Dictate the Pace
For Shandong's teapots, the calculus is straightforward: keep burning cash or cut runs until margins improve. Private refineries are expected to continue cutting utilization rates until the economics flip. Without government intervention propping up uneconomic plants, the sector is consolidating toward the strongest operators.
The pattern mirrors what happened during COVID, when weaker refiners idled capacity and larger players captured market share. This time the shock is supply-side rather than demand-side, but the outcome looks similar. Beijing appears willing to sacrifice marginal refining capacity to preserve inventories for more strategically important end-uses.
What Comes Next
Throughput could fall below 13 million barrels per day in June, continuing a slide from April's 44-month low of 13.35 million. Analysts expect the downtrend to persist until either Hormuz traffic normalizes or margins recover enough to justify imports from alternative sources.
The risk for markets sits on the demand side. If Chinese consumption stays weak, inventories will rebuild even at reduced run rates, capping any rally in crude. If demand snaps back or the Hormuz situation worsens, those buffers will draw down fast. Watch product inventory data over the next four weeks. A decline below 20 days of coverage would signal that the margin math is about to shift.
