Key Takeaways:
China's emergence as a swing importer in global oil markets, a trend that accelerated after the pandemic, is poised to reshape crude demand dynamics as Beijing and other major consumers begin replenishing strategic reserves.
China's role as a swing importer — cutting purchases by more than a third during the Iran war — is now expected to flip to a source of demand as the world's largest crude buyer joins OECD countries in refilling depleted strategic stockpiles.
"China has emerged as a swing importer since the pandemic, and we expect them along with OECD countries to start replenishing inventories, which will drive demand," Sara Vakhshouri, founder and president of SVB Energy International, said.
The shift comes after the Strait of Hormuz closure cut off a fifth of global oil and LNG supplies for more than three months, pushing Brent crude to nearly $120 a barrel. The IEA coordinated a record 400 million-barrel release from strategic petroleum reserves, while China — holding what is believed to be the world's largest SPR at more than 1 billion barrels — reduced crude imports by more than a third, saving billions of dollars by stepping away from a market of tight supply and high prices.
Combined, the need to refill roughly 400 million barrels already drawn from global stocks since the start of the war and the construction of new storage capacity requiring an estimated 500 million barrels could generate about 1 billion barrels of additional demand. Even spread over several years, that would provide significant price support for crude markets.
The Iran war exposed acute vulnerabilities in countries with limited emergency stockpiles. India, the world's third-largest oil importer and the single biggest source of global oil demand growth through 2030 according to the IEA, holds just eight days of import cover. Meeting the agency's 90-day standard would require more than 400 million additional barrels, costing roughly $28 billion at $70 a barrel. New Delhi has already asked Oil and Natural Gas Corp. to build a 1.75 million-tonne reserve that could expand India's emergency storage capacity by about one-third.
Australia, the only full IEA member that consistently failed to meet the agency's SPR requirement, has announced plans to spend $7 billion to hold at least 50 days of fuel. Pakistan, which relied on the Middle East for about 90% of its oil and LNG imports before the war, is also looking to expand domestic storage. Singapore and other Asian economies are considering building or expanding strategic oil and gas storage as well.
Even energy producers are moving. Saudi Aramco, which already operates storage facilities in Japan, South Korea, Egypt and northwest Europe, has signaled it is considering further expansion to preserve export flexibility in a crisis. Europe, where imported LNG now accounts for more than 40% of gas supply — with over 60% of those imports coming from the U.S. — may opt to build additional government-controlled storage.
The timing may be favorable for the buildup. The IEA expects global oil supply to surge next year as Middle East production recovers, potentially outstripping demand by more than 4 million barrels per day. A storage-driven demand increase of roughly 1 billion barrels spread over several years might therefore not send crude prices soaring — though that calculus could shift if Gulf supply recovers more slowly than expected because of logistical bottlenecks or a breakdown in the region's fragile new balance of power.
The longer-term implications of this urge to hoard are more complex. A world with significantly larger strategic reserves may prove more resilient to shocks, which could anchor prices over time. With greater buffers in place, countries such as India may reduce purchases during periods of tight supply — just as China did — dampening price spikes rather than amplifying them.
As the Hormuz shock subsides, the lesson for importers is clear: disruptions that once seemed impossible can happen, last longer than expected, and hit hardest where there is no cushion.
