Oil: the Chinese inventory that caps prices

As of 3 July 2026, Brent trades around $71 a barrel, down from $72.68 on 1 July. It is a counter-intuitive fact: a few weeks earlier, the partial closure of the Strait of Hormuz and the war around Iran had pushed the barrel toward $80, with a scenario at $105 if the strait stayed blocked. Yet the price came back down. Part of the explanation lies with an actor that produces almost nothing: China, the world’s largest crude importer. For the fundamentals, see our guide on reading the oil market.

The buyer that sets a floor, then a ceiling

Beijing’s role is double-acting, and that is what makes it poorly understood. In 2025, China played the role of a floor. Between January and August, it added about 900,000 barrels a day to its stocks, while Brent held around $68. Over that period, world inventories were swelling by 1.4 to 1.8 million barrels a day: China absorbed most of it. Without that appetite, according to the US Energy Information Administration (EIA), downward pressure on prices would have been far stronger. In other words, by buying cheap oil, China kept it from becoming even cheaper.

In 2026, the same mechanism flipped to set a ceiling. When the barrel jumped with the Iran crisis, China did not bid up. Its imports fell to 9.25 million barrels a day in April 2026, the lowest level since July 2022, a drop of about 2.4 million barrels a day year on year, nearly 20%. The utilisation rate of its refineries fell to its lowest since August 2022. Beijing stopped buying at high prices and preferred to live off its reserves. By refusing to fight other importers over scarce, expensive oil, China withdrew demand from the market at the worst moment, which mechanically capped the surge.

The war chest: 1.24 billion barrels

This discipline is only possible because China holds a considerable cushion. Its onshore crude stocks are estimated at about 1.24 billion barrels in April 2026, which would make it the largest national reserve on the planet. The figure remains an estimate: Beijing does not publish the detail of its strategic reserves, and analysts reconstruct it from import flows, satellite data and tanker tracking. The order of magnitude, however, is a consensus.

Notably, China kept filling its tanks even during the collapse in imports: between 430,000 and 580,000 barrels a day went into storage in April 2026, according to Reuters and Vortexa estimates. The fuel for this filling is not Gulf crude at market price, but discounted, sanctioned barrels bought at a rebate from Russia, Iran and Venezuela. About 166 million barrels of Iranian crude are said to be floating in Asian waters, positioned outside the Strait of Hormuz and closer to Chinese ports than to Middle Eastern terminals. Beijing can thus help itself from a stock already on the water, without fuelling the bidding war on the open market.

The limits of Chinese leverage

One must avoid attributing everything to Beijing. The retreat in Brent also owes, and perhaps above all, to two independent factors. First, the de-escalation around Iran lifted the geopolitical risk premium that was inflating the barrel. Second, supply is rising: seven OPEC+ countries are increasing production by 188,000 barrels a day from July 2026, after already raising their quotas by nearly 600,000 barrels a day between April and June. The market is slowly tilting from fear of shortage toward fear of surplus.

Chinese demand is therefore not the only brake, but it is the silent one. J.P. Morgan sees Brent at about $60 on average over 2026; the EIA even anticipated a trough near $52 in the first quarter. In a structurally well-supplied market, an importer able to cut its purchases by 2 million barrels a day without suffering becomes a de facto stabiliser. China did not decide to keep prices low out of benevolence: it buys when it is cheap and withdraws when it is expensive, in service of its own energy security alone. The ceiling on prices is a side effect of this methodical opportunism. One unknown remains: the day Beijing stops building reserves and starts selling them, the same leverage will work in the other direction.
