Hormuz risk premium rises as US military buildup near Iran lifts crude

Key Points:

• Brent above USD 71 reflects a strengthening geopolitical risk premium as traders price the risk of a prolonged conflict rather than a one-off shock
• Rather than repricing fundamentals, the latest move signals a market strengthening an already notable geopolitical risk premium as the world’s most important oil artery once again sits within striking distance of a conflict
• The vulnerability lies not only in Iran’s own exports but in the region’s dependence on the strait. Only Saudi Arabia and the United Arab Emirates possess meaningful bypass infrastructure.
• A prolonged disruption could accelerate rebalancing, reinforcing our medium-term bullish outlook for crude and oil majors

Brent crude’s move back above USD 70 a barrel signals a market strengthening an already notable geopolitical risk premium rather than repricing fundamentals. Reports that any potential US military operation could evolve into a weeks-long campaign, combined with Israeli pressure for an outcome targeting regime change in Tehran, have shifted trader focus from a headline shock to the risk of sustained disruption.

At the centre of market anxiety sits the Strait of Hormuz, one of the world’s most critical oil transit chokepoint. Roughly 19–20 million barrels per day of crude and refined products pass through the narrow waterway — close to one-fifth of global liquids consumption. The bulk originates from Gulf producers: Saudi Arabia exports roughly 6 mb/d through the strait, Iraq about 3.5–4 mb/d, the UAE and Kuwait each around 2–3 mb/d, Iran about 2–2.5 mb/d, and Qatar ships condensates and LNG volumes. Most of these flows are destined for Asia.

Limited alternatives to Hormuz

The vulnerability lies not only in Iran’s own exports but in the region’s dependence on the strait. Only Saudi Arabia and the United Arab Emirates possess meaningful bypass infrastructure.

Saudi Arabia’s East-West Petroline allows crude to be moved from Abqaiq to the Red Sea port of Yanbu, while the UAE’s Abu Dhabi Crudes Oil Pipeline transports crude from Habshan to Fujairah outside the Gulf. Combined, these routes could redirect several million barrels per day, but practical spare bypass capacity is likely around 2–3 mb/d, far short of the roughly 20 mb/d that normally transits Hormuz.

This leaves the global market exposed: even partial disruption would force rerouting, insurance spikes, and logistical bottlenecks long before a full blockade becomes reality.

Iran exports and China’s central role

Iran currently exports roughly 1.3–1.5 mb/d of crude, despite sanctions. More than 80% of these shipments are estimated to end up in China, primarily purchased by independent refiners attracted by discounted barrels.

This concentration matters. Should exports be disrupted, the immediate demand shock is concentrated in China. Conversely, if prices spike, China could dampen market pressure by drawing from strategic reserves and temporarily reducing imports.

More broadly, Asia dominates Middle East crude demand. Around 80%+ of Hormuz flows head east, with China, India, Japan, and South Korea the primary buyers. Europe’s direct exposure is limited, but price formation through the London-based Brent crude futures contract remains global.

Oversupply exists — but not where it matters

Despite geopolitical tensions, oil prices have not collapsed under the weight of a much talked about global surplus. Goldman Sachs highlights a key disconnect: much of the surplus has accumulated in sanctioned crude floating at sea rather than in OECD storage hubs that influence pricing.

Crude on water from Russia, Iran, and Venezuela has according to their estimates climbed to roughly 375 million barrels, accounting for a significant share of visible global inventory growth. These barrels do not ease prompt market tightness in pricing centres, helping explain why oil prices remain supported even amid headline oversupply.

In other words, the market can appear oversupplied on paper while still paying up for immediately deliverable barrels.

Strategic buffers: China and the US

China’s stockpiling in recent years gives it flexibility during price spikes. By drawing inventories and slowing imports, Beijing can moderate demand shocks.

The United States also retains a buffer. The Strategic Petroleum Reserve has rebounded to roughly 415 million barrels from a 2023 low near 347 million. While releases can dampen domestic fuel inflation, they are politically sensitive and complicated by the need to eventually refill stocks.

Domestic politics may constrain escalation risk

US domestic politics remain a critical variable. Higher crude prices feed directly into gasoline costs, and with affordability a central voter concern ahead of the November midterm elections, a sustained rise in gasoline prices would create political headwinds. Even if Washington can tolerate higher crude prices strategically, it has limited appetite for visible consumer pain.

Risk premium vs fundamentals

The current market backdrop remains one of adequate supply, robust demand, and rising non-OPEC output. Yet pricing reflects tail risk rather than base-case fundamentals.

A temporary disruption would likely produce a sharp but short-lived spike. A prolonged closure or sustained harassment of shipping would be far more consequential, especially given the limited bypass capacity and Asia’s heavy dependence on Hormuz flows. Beyond the immediate price impact, a sustained disruption would also accelerate the drawdown of the current supply overhang, potentially bringing forward the timing of a more balanced market — a shift that would strengthen underlying fundamentals and support our medium-term bullish outlook for crude and oil majors.

For now, crude above USD 70 reflects a market reintroducing geopolitical insurance into pricing — not a verdict that disruption is imminent, but recognition that the world’s most important oil artery sits within striking distance of conflict.
