Oil Price Surge: $100 Brent on Flow Shock

The market's immediate reaction to the strikes was a sharp, one-day surge. On February 27, Brent crude oil rose to 72.87 USD/Bbl, a gain of 2.87% in a single session. This move pushed the benchmark to a seven-month high, confirming the market's nervous response to the sudden escalation in the Middle East.

The disruption to physical flows is already material. Major oil traders have suspended crude oil and fuel shipments via the Strait of Hormuz due to the attacks. This creates a tangible, on-the-ground flow shock, as the strait carries about 20% of global daily oil supply. The market is now pricing in the risk that this suspension could become a blockade, a scenario that could impact over 20% of global oil and LNG flows.

The key test for price stability comes when trading resumes. Analysts expect crude to almost certainly jump when electronic markets reopen Sunday night. The magnitude of that move will depend directly on whether the flow disruptions to the strait are confirmed and sustained, turning a geopolitical risk premium into a physical supply shock.

The Supply Disruption Math

The potential volume at risk is substantial. Iran produces about 3.3 million barrels a day, and exports roughly 1.6 million barrels a day. This export volume, primarily to China, represents a significant chunk of global supply. The real threat, however, is not just Iran's own flows but the strategic chokepoint it controls. The Strait of Hormuz carries about a fifth of the world's crude, making any closure a direct threat to a massive portion of global oil and LNG shipments.

Analysts project a sharp price response to this threat. Energy analysts at Barclays predicted crude oil prices would hit $100 a barrel as the market grapples with the potential supply disruption. The scale of the move depends entirely on the conflict's duration and whether energy assets are directly targeted. As one analyst noted, the exact move will hinge on how deep and prolonged the attacks are and whether oil flows are materially disrupted.

The market is already pricing in this risk. Benchmark Brent crude closed at a seven-month high on February 27, and prices are expected to jump sharply when electronic trading resumes. The key uncertainty is whether the threat of a prolonged blockade or direct attacks on export terminals like Kharg Island translates into a sustained physical supply shock. For now, the flow shock is a geopolitical risk premium, but its conversion into a permanent price increase depends on the conflict's evolution.

The OPEC+ Response and Market Liquidity

The immediate counter-flow mechanism is pressure on OPEC+ to raise production. As regional instability grows, the group faces mounting calls to offset any physical supply disruption. However, its ability to act is constrained by existing supply agreements. The market is looking for a coordinated response, but the group's capacity to ramp output quickly is limited by these commitments.

A prolonged conflict would force Asian refineries, which rely heavily on Iranian oil, to seek alternative sources. This scramble for supply would push up global prices further, as buyers compete for available barrels. The real risk is not just to Iran's own exports but to the strategic chokepoint it controls. The Strait of Hormuz carries about a fifth of the world's crude, making any closure a direct threat to a massive portion of global oil and LNG shipments.

The primary risk is to the Strait of Hormuz, a chokepoint for roughly 20% of global oil. A full closure would be a 50% premium event, according to analysts. Even a partial disruption, as tankers avoid the region, could see several million barrels per day of oil disrupted. This would send prices over $100, with the market pricing in higher risk of various scenarios that may disrupt supply.
