Conflict in the Gulf: Impact on Global Oil and LNG Markets

Escalating tensions in the Middle East over the weekend create immediate sensitivity in global oil and LNG markets, particularly because of the strategic importance of the Strait of Hormuz and the broader Gulf shipping routes. The legal and commercial impact on the oil and gas industry will depend heavily on the duration and intensity of the conflict.

Crude prices have been creeping up for weeks based largely on concerns about the threats to oil supplies and trade if the U.S. did attack Iran. Despite ongoing sanctions, Iran is still a significant oil exporter. Most of Iran’s exported oil goes to China. However, the conflict has much wider ranging implications than simply on Iran’s oil exports. Iran controls the Strait of Hormuz, a vital shipping route. About 20 million barrels of oil and oil products pass through every day, which is about 20% of global oil demand. 

In a short-lived or quickly resolved escalation, the primary effect will materialise as a sharp but temporary spike in oil and LNG prices. Markets typically incorporate a geopolitical “risk premium,” even in the absence of physical supply disruption. In such circumstances, contractual performance under long-term supply agreements generally remains intact, and force majeure provisions are unlikely to be successfully invoked unless there is demonstrable impossibility. Principal concerns would instead revolve around price indexation mechanisms, margin calls under hedging agreements, and short-term liquidity pressures.

By contrast, a prolonged conflict carries significantly more profound legal and structural implications. Sustained hostilities could disrupt shipping, trigger expanded sanctions regimes, increase war-risk insurance premiums, or impair infrastructure in the Gulf. In that scenario, parties across the value chain, from upstream producers to downstream utilities, will look to force majeure, hardship, or change-in-law clauses. Long-term oil-indexed LNG contracts could come under strain, particularly where delivery becomes commercially impracticable. Additional volatility can metamorphose into price dislocation which may give rise to requests for price reviews in due course. 

Governments may intervene through export controls, strategic reserve releases, or emergency energy measures, further altering contractual risk allocation. The result could extend beyond volatility into a broader energy crisis marked by supply shortages and regulatory intervention.

European energy providers are particularly exposed where they rely on long-term supply arrangements with producers in Qatar. Many European utilities structure their electricity sales based on anticipated LNG deliveries under long-term Qatari contracts. If geopolitical instability impairs deliveries or diverts volumes toward higher-priced markets, European buyers may be forced to secure replacement cargoes on the U.S. spot LNG market, where prices will have inevitably spiked. This substitution risk creates immediate margin pressure, particularly where electricity has already been forward-sold at fixed prices. Ultimately, the distinction between a short-term geopolitical shock and a prolonged conflict is critical. A brief escalation primarily affects pricing dynamics and liquidity management. A sustained conflict, however, has the potential to destabilize contractual performance across the oil and LNG value chain, increase dispute frequency, and place European energy providers in a structurally vulnerable position as they pivot from long-term Gulf supply to higher-cost and less predictable spot market alternatives.
