Key Takeaways:
WTI crude climbed 4% to $81.33 a barrel Monday, the latest leg of a rally that has redrawn global energy flows since the Iran war closed the Strait of Hormuz.
WTI crude climbed 4% to $81.33 a barrel Monday, extending a rally that has redrawn global energy flows since the Iran war closed the Strait of Hormuz, the passage for roughly a fifth of the world's oil.
"China's reduced imports have acted as a pressure valve for the global market, keeping prices from spiking toward $200 a barrel," said Rory Green, head of emerging markets research at TS Lombard.
China, the world's largest crude importer, has cut oil purchases roughly 50 percent since the conflict began, drawing down inventories rather than bidding up cargoes. Beijing's strategic reserves and commercial stockpiles give it about two months of cover before domestic stress builds, Green estimated. The supply shock has rippled across asset classes: the European Central Bank raised its main rate to 2.25 percent in June to counter war-driven inflation, while the Federal Reserve has cut three times since September 2025 to a range of 3.5 to 3.75 percent.
The question is how long the buffer holds. If the strait stays shut beyond two months and China's reserves run low, Beijing could return to the market aggressively to refill stockpiles, pushing prices higher and intensifying the shock it has so far absorbed.
China's buffer narrows the shock
Beijing has spent more than a decade preparing for a disruption of this scale, building four buffers that Green says make the economy unusually resilient: commodity stockpiles, petrochemical capacity, low inflation and a large electrification build-out. Erica Downs, senior research scholar at the Center on Global Energy Policy at Columbia University, frames the strategy as a long-standing ambition to become an "energy powerhouse" — sourcing as much energy domestically as possible, which means more renewables and coal, with plans to peak coal consumption by 2030.
Yet the shield is not airtight. Oil remains hard to displace in aviation, legacy vehicle fleets and petrochemical feedstocks, and China still depends heavily on imported crude and gas. Overland supply lines with Russia have reduced exposure to maritime chokepoints, but Beijing is wary of trading one geopolitical vulnerability for another. Downs noted that President Vladimir Putin's recent visit to Beijing produced no announcement on the proposed Power of Siberia 2 pipeline, a signal that China may prefer to move away from imports altogether.
What happens if the strait stays shut
The market's near-term path hinges on expectations. If Chinese authorities believe the disruption will exceed their buffer window, their response could flip fast, returning to the market aggressively and driving prices into extreme territory. Green expects Beijing to slow purchases when prices spike and "buy the dip" once the strait reopens, then rebuild stockpiles and push to reduce financial exposure through renminbi internationalization.
For now, the rally has also lifted borrowing costs: average UK two-year fixed mortgage rates edged up to 5.63 percent as lenders repriced against renewed Middle East turmoil, while the Bank of England held its base rate at 3.75 percent. Each new disruption, Green argues, will accelerate Beijing's push for energy self-sufficiency — a shift that could keep oil prices structurally supported even after the current crisis eases.
