Impact of Strait of Hormuz Disruptions on Global LNG Markets Compared to Oil

The Strait of Hormuz is a narrow waterway that plays a critical role in global energy supply. It connects the Persian Gulf with the Gulf of Oman and the Arabian Sea, serving as a key transit route for oil and liquefied natural gas (LNG). When disruptions occur in this chokepoint, the effects ripple through global markets. Yet, the impact on LNG markets tends to be more severe than on oil. Understanding why requires looking at the differences in supply chains, market flexibility, and infrastructure.

Why the Strait of Hormuz Matters for Energy

About 20% of the world’s oil passes through the Strait of Hormuz daily. This includes crude oil from major producers like Saudi Arabia, Iran, Iraq, and the United Arab Emirates. The volume of oil transported here is enormous, but the global oil market has developed mechanisms to handle short-term disruptions. These include strategic petroleum reserves, alternative shipping routes, and diversified supply sources.

In contrast, LNG exports through the Strait are more vulnerable. Qatar, the world’s largest LNG exporter, relies heavily on this route to ship gas to Asia and Europe. Unlike oil, LNG requires specialized infrastructure such as liquefaction plants and cryogenic tankers. This makes rerouting or quickly replacing lost shipments much harder.

Differences in Market Flexibility

Oil markets benefit from a global network of pipelines, storage facilities, and refineries that provide flexibility. When the Strait of Hormuz faces disruption, oil producers can often redirect shipments through pipelines to other ports or tap into reserves. Buyers can also switch to alternative suppliers more easily because oil is a fungible commodity traded on global exchanges.

LNG markets, however, are less flexible. LNG cargoes are typically sold under long-term contracts with fixed destinations. The specialized nature of LNG carriers means they cannot easily change routes or destinations without incurring significant costs and delays. This inflexibility means that any disruption in the Strait of Hormuz can cause immediate shortages and price spikes in importing countries.

Infrastructure and Storage Constraints

Oil storage capacity worldwide is vast, allowing buyers to stockpile supplies during times of uncertainty. This buffer helps smooth out supply shocks caused by transit disruptions. LNG storage, on the other hand, is limited and expensive. LNG must be stored at extremely low temperatures, requiring costly facilities that are not as widespread.

Moreover, LNG production is a continuous process. If shipments are delayed or blocked, producers cannot easily pause liquefaction without risking damage to equipment or losing product. This contrasts with oil, which can be stored in crude form more easily.

Real-World Examples

In 2019, tensions in the Strait of Hormuz led to attacks on oil tankers and threats to close the waterway. Oil prices rose but stabilized quickly due to strategic reserves and alternative supply routes. Meanwhile, LNG markets saw sharper price increases, especially in Asia, where demand is high and alternative suppliers are limited.

The COVID-19 pandemic also highlighted LNG’s vulnerability. When shipping routes were disrupted, LNG cargoes faced delays and cancellations, causing supply shortages in key markets. Oil markets, by comparison, adjusted more smoothly through changes in production and storage.

What This Means for Global Energy Security

The Strait of Hormuz remains a critical vulnerability for global energy markets, especially for LNG. Countries dependent on LNG imports must consider diversifying supply sources and investing in storage and infrastructure to reduce risks. Policymakers and industry players should also focus on developing alternative shipping routes and enhancing regional cooperation to ensure supply stability.
