China Orders Refiners to Maintain High Output Amid Persian Gulf Supply Risks
Taylor Wilson
China has told at least two major refineries to maintain or raise run rates, bracing for a possible crude-supply disruption in the Persian Gulf. But with domestic fuel stockpiles already elevated and consumption slowing, forced high output risks squeezing refining margins further.
Why is Beijing telling refiners to run flat out?
At least two major refineries received instructions to maintain or raise operating rates, according to Bloomberg citing people familiar with the matter.
Two triggers converged: violence in the Iran war escalated again, and the U.S. revoked waivers that had permitted Iranian oil sales.
This means → the earlier interim U.S.–Iran ceasefire is at risk of collapse, and Beijing fears Persian Gulf crude supplies could be cut off — so it is getting refiners ready early.
Stockpiles are already high — why produce more?
China's gasoline and diesel inventories are both at elevated levels, and consumption of both fuels is in structural decline.
In plain terms = fuel is already hard to sell, and warehouses are far from empty — but the government still wants more refining. The worry is not "we don't have enough now" but "if overseas supply is cut, we can't ramp up fast enough."
This reflects a deliberate trade-off: Beijing would rather overproduce and depress prices than risk a supply gap.
What does high output mean for refining margins?
Mandated high run rates will push up refined-product output, adding pressure to regional refining margins while demand stays weak.
Bloomberg data show the spread between Asian gasoline prices and Dubai crude has fallen to its lowest since late March.
This means → every extra barrel a refiner processes earns a thinner crack spread — the policy protects supply security at the cost of refiner profitability.
Will export quotas be loosened in parallel?
People familiar with the matter say July fuel-export quotas will not be adjusted.
Early in the Iran war, China restricted gasoline, diesel, and jet-fuel exports to secure domestic supply; restrictions were later eased, and additional export permits were issued earlier this month.
In plain terms = output is rising and the export tap is no longer tightening — the extra fuel can go to domestic stockpiles or overseas buyers, but the price those buyers will accept keeps falling.
What is the market watching next?
The core variable is a single question: will high run rates effectively hedge supply risk, or will they accelerate the squeeze on refinery margins?
If the Persian Gulf situation truly deteriorates, pre-positioned output is insurance well bought. If tensions ease, the surplus becomes a drag on prices.
This reflects a policy that is, at its core, a risk bet — if Beijing reads the situation right, it is prudent preparation; if wrong, it is self-inflicted margin damage.
