Global oil markets remain highly volatile in 2026, shaped by extreme price swings and escalating geopolitical risk, but stabilizing force has been China’s role as the world’s dominant swing buyer.

Unprecedented supply disruptions tied to conflict involving Iran triggered both the sharpest price surge and collapse on record within a matter of months, according to S&P Global Energy. Prices spiked to $144.42/bbl in early April before falling to $69.35/bbl on July 3. Following the breakdown of the US-Iran ceasefire, supply shortfalls from the Middle East have widened again, pushing prices back into the $80-100/bbl range.

Throughout this volatility, China has emerged as a critical demand-side buffer. Since May, the country has reduced seaborne crude imports by roughly 5 million b/d—about a 45% decline—helping offset lost Persian Gulf supply and limit further price escalation. By contrast, crude imports in the rest of the world have remained close to pre-conflict levels.

“China has acted as the swing buyer since oil flows in the Strait of Hormuz were disrupted,” said Jim Burkhard, vice president and global head of crude oil research at S&P Global Energy. “The reduction of its crude imports was the biggest reason prices fell so sharply from April to July, and it is why they have not gone even higher since the war heated back up.”

Despite the steep drop in imports, China’s underlying oil demand has declined far less. S&P Global estimates second-quarter demand was down 1.6 million b/d year-over-year, far less than the 5 million b/d decline in imports. Commercial crude stocks, estimated at around 1.5 billion bbl, have enabled Beijing to sustain consumption while sharply reducing purchases.

Measured against a February pre-war baseline of roughly 20 million b/d, as of late July, the shortfall in crude and condensate shipments from the Middle East Gulf region—including routes that bypass the Strait of Hormuz—has widened to roughly 10 million b/d. That gap had previously narrowed to 3-4 million b/d in June. By comparison, disruptions averaged 11.5 million b/d from April to mid-June.

Additionally, Houthi attempts to block maritime traffic through the Red Sea have added a new layer of risk, jeopardizing some of the 4-5 million b/d being shipped through the port of Yanbu.

“The margin for error has narrowed,” Burkhard said. “The market still has buffers, but they are conditional, political, and unevenly distributed. China is by far the most important offset.

“Every buyer would like to have the flexibility to adjust purchases to market conditions. But few can move the market the way China can. The market’s balance now depends heavily on a choice that Beijing can change. That is one reality that the Hormuz crisis has revealed.”
