OPEC+ Influence Fades as China Becomes Oil Market's Swing Force
OPEC+ market share drops to 40% as Iran war blocks exports; China's import cuts now balance global oil prices.
Six months into the Iran war, OPEC+ is discovering that its once-dominant grip on global oil markets has slipped. The alliance, which includes Russia and other major producers, now accounts for just 40% of world output — down from over 48% before the conflict began in late February. A significant portion of that decline stems from the UAE's exit from OPEC in May, but the war has compounded the loss by shutting the Strait of Hormuz, a vital route for Saudi Arabia, Iraq, and Kuwait.
With exports physically constrained, the group's policy decisions have lost their punch. Since March, OPEC+ has announced six output increases, yet most have remained theoretical due to the blockade. Oil prices have barely reacted, except for a brief uptick in July during a short-lived ceasefire that raised hopes of reopening Hormuz.
The contrast with 2019 is stark. Back then, traders hung on every OPEC+ decision, and the key question was how much oil the group would pump. Today, the focus has shifted to how much can actually be produced and shipped amid an active war zone.
Meanwhile, China has quietly stepped into a role once reserved for OPEC+: the swing force in oil markets. Since the war began, Beijing has imported roughly 400 million fewer barrels than in the same period last year, driven by a fuel export ban, lower refinery output, and the rapid adoption of electric vehicles. These cuts have helped cap prices during one of the worst supply disruptions on record.
Analysts note that China's reduced appetite has become a balancing mechanism, much as OPEC+ once used its spare capacity to steady the market. Last year, by contrast, Chinese buying accounted for as much as half of global demand growth, underpinning prices. Now, as one analyst put it, China has become the "swing demand centre" of the oil world.
For OPEC+, the irony is sharp. The alliance was formed in 1960 and expanded in 2016 to counter shrinking market share. Its influence peaked during the 1970s oil crises at around 50% of global output, before falling to 30% by the mid-1980s. The current war has accelerated a similar decline, leaving the group with less leverage than at any point in recent memory.
