The halt of Qatari liquefied natural gas (LNG) production and the disruption of flows through the Strait of Hormuz, following attacks on its facilities in the wake of regional conflict, will have significant ripple effects on global energy markets if prolonged. The immediate market reaction saw European gas benchmark prices surge by as much as 40%, while the US Henry Hub benchmark saw a more modest increase.

Market Impact and Supply Disruption

The disruption is critical because approximately 20% of global LNG supply, or around 81 million tonnes, transits the Strait of Hormuz, with most volumes destined for Asian markets. The loss of this supply, particularly Qatar's substantial contribution, is expected to have major short-term ramifications. The extent of the impact hinges on the conflict's duration and the damage to energy infrastructure.

Shifting Trade Flows and Price Pressures

The situation may alter global LNG trade patterns. With Qatar offline, increased demand for alternative supplies is anticipated. If US LNG, which has largely flowed to Europe since 2022, must be rerouted to Asia to fill the gap, it would further tighten shipping markets. This rerouting would have clear ramifications for European gas prices. Concurrently, Asian markets face immediate pressure due to their heavy reliance on Qatari supply, with each day of disruption creating backup demand.

Regional Vulnerabilities and Secondary Effects

Specific Asian markets, including Japan, Korea, Taiwan, India, and Thailand, are identified as being most exposed to the Qatari supply shutdown. The disruption also involves Abu Dhabi's supply, which primarily serves Asian markets. Beyond commodity prices, the crisis is impacting shipping, with freight rates spiking alongside benchmarks. The ability to physically move cargoes is becoming a critical and costly factor. Furthermore, Europe enters this period with historically low gas storage levels, which could exacerbate market tightness, though warmer upcoming weather may provide some relief.
