What Drives LNG Prices?

Weather is the single most acute short-term driver of LNG price volatility. Cold winters in Japan, Korea, and China drive emergency LNG procurement that sends spot prices sharply higher. Hot summers in China and Korea boost air-conditioning demand, adding a second seasonal price peak (typically July–August). The 2021 winter demand surge and the 2022 European energy crisis both had significant weather components.

Winter LNG demand in Japan and Korea is relatively predictable but its magnitude varies significantly year to year. Chinese demand is the swing factor — when China enters the spot market aggressively during cold weather, the impact on JKM is immediate. European weather increasingly matters as Europe has become a major LNG consumer. Cold Northern European winters now compete directly with Asia for LNG cargoes.

LNG supply is inelastic in the short term — you can’t build a new export terminal in months. Global LNG liquefaction capacity is dominated by Qatar (~80 mtpa, the world’s largest single exporter), Australia (~80 mtpa across multiple projects), US Gulf Coast (~120 mtpa of operational and approved capacity), and Russia (Yamal LNG, Sakhalin, now subject to sanctions risk). When a major export facility experiences an unplanned outage — as happened with Freeport LNG in 2022 (8 months offline) — spot prices spike globally.

New LNG supply capacity coming online between 2025–2028 from the US and Qatar is expected to significantly increase global LNG availability, which is a structural bearish pressure on LNG prices in the medium term. However, demand growth from South and Southeast Asia (India, Pakistan, Bangladesh, Vietnam) is absorbing new supply.

Shipping economics are the hidden driver of LNG arbitrage. A typical US Gulf Coast to Asia voyage costs approximately $1.50–$2.50/MMBtu in freight, taking 15–25 days. This freight cost sets the minimum JKM-TTF spread required for Atlantic-to-Pacific cargo redirection to be economically viable. When the spread is below freight costs, cargoes stay in the Atlantic basin (Europe); when above, they divert to Asia.

Canal constraints are particularly impactful. Panama Canal draught restrictions (driven by La Niña drought conditions) add 15–20 days to US-to-Asia routes via Cape Horn, significantly increasing effective freight costs. Red Sea disruptions (Houthi attacks since late 2023) have rerouted Middle East and European LNG flows around the Cape of Good Hope, adding cost and voyage time. These constraints effectively tighten global LNG supply, supporting prices.

Geopolitical events are the most unpredictable and violent LNG price driver. The Russia–Ukraine war (February 2022) eliminated approximately 150 bcm/year of Russian pipeline gas supply to Europe, triggering an emergency European LNG import surge that sent TTF to record levels and pulled JKM sharply higher as Europe competed with Asia for every available cargo. Middle East conflicts threaten Strait of Hormuz transits, through which approximately 20% of global LNG passes from Qatar and UAE export terminals.

EnergyRiskIQ’s GERI (Global Energy Risk Index) quantifies geopolitical and supply-chain risk across 100+ countries, providing an early-warning signal for LNG price stress. GERI is currently at 17/100 (LOW) — reflecting low geopolitical supply risk in global energy supply corridors today.

A significant share of LNG is sold under long-term contracts indexed to crude oil — typically at 13–15% of Brent crude price per barrel. With Brent at $93.31/bbl today, the oil-indexed LNG formula reference is approximately $12.60/MMBtu. When JKM spot trades significantly above this level, buyers seek more spot supply and push back on oil-indexation in new contracts. When below, it signals LNG spot oversupply.

Oil prices also drive fuel switching. When oil-based fuels (diesel, fuel oil) are expensive relative to LNG, industrial and power buyers substitute towards gas, increasing LNG demand. Conversely, when oil is cheap, LNG demand softens in dual-fuel applications. Brent is currently ▼ $93.31/bbl (-1.73 day-on-day).

The single most transformative structural change in LNG markets since 2022 is the permanent entry of Europe as a major LNG spot buyer. Before 2022, European gas was largely supplied by Russian pipelines; since the war, Europe has pivoted to LNG, importing 120+ bcm/year equivalent and competing directly with Asia for every flexible cargo.

The JKM-TTF arbitrage spread determines where flexible LNG cargoes (primarily from the US Gulf Coast) are directed. Today’s spread of approximately $4.55/MMBtu (JKM premium — Asia attracting LNG cargoes). EU gas storage at 39.1% sets the urgency of European LNG demand — when storage is low, European buyers bid aggressively, diverting cargoes from Asia and lifting both TTF and JKM simultaneously. EERI at 15/100 (LOW) reflects current European supply stress.

Gas storage levels are the primary buffer between supply disruption and energy crisis. Europe’s gas storage fills up between April and October (injection season) and draws down October to March (withdrawal season). EU regulations require storage to be at least 90% full by November 1 each year. When storage is below target, European buyers must procure LNG aggressively, competing with Asian buyers and lifting global LNG prices. When storage is full, European LNG demand softens and JKM can trade at a discount to TTF.

Today, EU gas storage stands at 39.1% — below the 55.0% seasonal norm by 15.9 percentage points. This below-normal storage level creates urgency for European LNG procurement and supports JKM prices. Panic buying events — as seen in Q3 2022 — can push LNG prices to extreme levels when storage is critically low and winter approach accelerates procurement urgency.
