The Iran war is delivering a painful financial shock to oil refiners across Asia. As the benchmark Dubai crude price surges in the wake of the Middle East conflict, refiners who had locked in prices through hedging contracts are now staring down losses they did not see coming.
How Hedging Works, and Why It's Failing
Oil refiners routinely use financial instruments to hedge against price swings, locking in purchase prices in advance to manage costs and protect profit margins. The strategy works well in stable or predictably moving markets. It breaks down when prices move violently in one direction.
The U.S.-Israel attacks on Iran that began February 28 triggered exactly that kind of violent move. The Strait of Hormuz, through which roughly 20% of global oil and LNG flows, has been largely closed by Iranian drones and naval mines, sending crude prices spiralling upward. Brent crude has surged roughly 50%, reaching approximately $106 per barrel.
Dubai Benchmark at the Centre
For Asian refiners, the relevant benchmark is Dubai crude, which underpins a large share of oil contracts in the region. As that price soared, refiners who had sold hedges at lower price levels, betting prices would stay flat or fall, found themselves on the wrong side of the trade.
According to traders cited by the Financial Post, the losses are deep and widespread. The magnitude of the move was simply outside the range that most hedging models had anticipated.
Broader Economic Fallout
The losses for individual refiners are part of a larger economic disruption rippling across Asia. Japan has already begun releasing strategic oil reserves as markets face severe supply constraints. Energy-intensive industries across South Korea, Japan, and Southeast Asia are grappling with sharply higher input costs.
For consumers, the effect is straightforward: higher fuel and electricity prices. In the United States, surging petrol prices are already creating political headaches for the Trump administration.
No Quick Fix in Sight
With the conflict now in its third week and no ceasefire on the horizon, there is little relief in sight for Asian refiners. The Strait of Hormuz remains a choke point, diplomatic efforts to reopen it have stalled, and the U.S. marine deployment is weeks away from arriving.
For refiners, the immediate challenge is managing the damage from existing hedging positions while navigating one of the most volatile oil markets in decades.
