US-Israel-Iran Conflict Disrupts Global LNG Supplies, Threatening Energy Security Worldwide
The ongoing United States-Israeli conflict with Iran has triggered severe disruptions to global LNG supplies in the Gulf, creating the most significant energy market disruptions in recent years. The critical Strait of Hormuz, through which 27 percent of the world's maritime oil trade and 20 percent of LNG shipments pass, has been brought to a near standstill.
In response to the conflict, oil-producing nations such as Saudi Arabia have rerouted oil through alternative pipelines, while Qatar has completely halted LNG production at its Ras Laffan and Mesaieed facilities following attacks on its energy infrastructure. This disruption comes as natural gas makes up about a quarter of global energy consumption, raising widespread concerns about the impact on nations heavily reliant on gas imports.
Natural gas is formed over millions of years from decomposed organic matter subjected to intense heat and pressure beneath the Earth's surface. LNG represents natural gas that has been cooled to -162 degrees Celsius through cryogenic processing, shrinking it to a 600th of its gaseous volume. In its liquid state, LNG is colorless, odorless, and non-flammable, making it safe and efficient to transport across vast distances.
Before liquefaction, the gas undergoes purification through water-based solvents and molecular sieve beds to remove impurities including carbon dioxide, hydrogen sulfide, water, and mercury. Heavier hydrocarbons are then separated from methane and ethane through fractionation. The resulting fuel is typically composed of 85 to 95 percent methane, with small amounts of ethane, propane, butane, and nitrogen.
LNG is stored in large insulated tanks without requiring high-pressure infrastructure, then pumped onto double-hulled carriers for shipment to terminals worldwide. At destination facilities, LNG is heated using seawater or warm water baths until it vaporizes—a process known as regasification—before being distributed through pipelines for consumption.
Once returned to a gaseous state, LNG serves multiple purposes globally. Residential applications include cooking, heating, and electricity generation, while supporting hot water systems in homes and heating for commercial buildings. In power generation, LNG offers a comparatively low-carbon alternative to coal and oil. Industrial applications span fertilizers, plastics, paints, and medicines, with LNG also used to fuel heavy-duty vehicles and ships.
The disruption has particularly affected agricultural production, as Gulf nations export close to half the world's traded urea—a key fertilizer component. Natural gas serves as both the primary feedstock and fuel for fertilizer manufacturing, with the halt in production forcing producers across the region to suspend or reduce operations.
While primarily valued as an energy source, LNG processing yields significant by-products with industrial and medical applications. The most notable is helium, extracted during cryogenic processing. With global helium production estimated at 180 million cubic meters annually, the disruption to Qatar's LNG facilities has removed approximately 5.2 million cubic meters from the market each month—accounting for about a third of global monthly production.
Helium is critical for cooling superconducting magnets in MRI and CT scanners, with the average MRI machine requiring about 1,700 liters of liquid helium. The element is also vital to the data center industry, where it conducts heat away from silicon components, preventing damage to semiconductors. Additionally, the natural gas value chain generates petrochemical derivatives that serve as feedstock for manufactured goods, including medical-grade plastics.
According to the International Gas Union's 2025 World LNG Report, 411.24 million tonnes of LNG were traded in 2024. The United States emerged as the largest exporter with 88.4 million tonnes, followed by Australia (81 million tonnes), Qatar (77.2 million tonnes), Russia (33.5 million tonnes), and Malaysia (27.7 million tonnes). Together, these top five suppliers account for more than three-quarters of global LNG supply.
China was the largest importer with 78.6 million tonnes in 2024, followed by Japan (67.7 million tonnes), South Korea (47.1 million tonnes), India (26.1 million tonnes), and Taiwan (21.8 million tonnes). These top five importers constituted nearly 59 percent of all global LNG imports that year.
South Asian nations face particularly severe risks from the current conflict. Pakistan, where natural gas accounts for 28 percent of electricity generation for its 250 million people, and Bangladesh, where gas supplies half of all electricity for its 176 million population, are heavily dependent on Gulf imports. Qatar and the United Arab Emirates supply approximately 99 percent of Pakistan's LNG imports and 72 percent of Bangladesh's.
In response to the energy crisis, Pakistan has implemented emergency measures including a four-day workweek for government employees and extended school holidays. Bangladesh has reduced gas supplies and is seeking nearly $2 billion in international loans to fund energy inputs and maintain price stability. India, which relies on Gulf nations for about half of its LNG and generates 5 percent of its electricity from gas, has shifted toward coal usage as LNG disruptions continue.
