Global LNG demand and LNG exporters under a Super El Niño scenario: Bernstein sees a Super El Niño cutting global LNG imports by only about 1%, leaving LNG exporters largely unaffected.

Overview

Bernstein examines whether a forecast 2026–27 Super El Niño could materially weaken LNG demand, particularly in Asia. Its conclusion is that the weather effect would be modest relative to ordinary market variability and would not create a meaningful negative demand shock for LNG exporters.

Core views

Bernstein frames the question around Asia, which accounts for approximately 62% of global LNG imports and is more directly exposed to El Niño-related weather changes than Europe or MENA. The report notes that the forecast 2026–27 event could be among the strongest in recent decades, with the Relative Oceanic Niño Index (RONI) above 2.5°C. El Niño is expected to bring warmer, drier conditions to much of South and Southeast Asia, potentially reducing heating needs during winter. The analysis uses Japan as a proxy for Asia because it lies in an area materially affected by El Niño, is the world’s second-largest LNG importer, and imports virtually all of its gas through LNG. Bernstein finds a strong relationship between Japanese LNG consumption and heating degree days (HDDs), but virtually no relationship between consumption and cooling degree days (CDDs). Its estimated relationship indicates that each additional degree below the 18°C reference temperature corresponds to approximately 0.01 BCFD of additional Japanese LNG consumption per day. To model a Super El Niño, Bernstein begins with the 2023–24 El Niño winter and applies the forecast 1.2°C RONI increase for 2026–27. It subtracts 36 HDDs from each winter month, calculated as 1.2 degrees multiplied by 30 days. This produces an estimated 19% decline in Japanese winter HDDs versus the prior year. Yet the resulting implied Japanese winter LNG consumption is 9.1 BCFD, only 2% below the preceding season; the difference is 0.19 BCFD versus 9.29 BCFD of Japanese winter consumption. The limited response reflects a substantial baseload of demand that is relatively insensitive to weather. Bernstein then applies the 2% Japanese consumption decline to Asian imports, using imports as a proxy for demand. The approach is deliberately conservative: it applies the impact to the full year even though the effect should be strongest in winter, and assumes the full El Niño effect is realized in 2026. This yields a reduction in Asian LNG imports of less than 0.7 BCFD, equivalent to about 1% of global LNG imports. Bernstein considers that change immaterial given historical year-on-year swings in Asian imports ranging from -11% to +23%. Historical evidence further supports the report’s conclusion: despite the positive HDD-consumption relationship, the prior El Niño year recorded higher Japanese LNG consumption than the following two years. Bernstein therefore argues that LNG demand is more influenced by structural and market factors—including storage, fuel-switching economics, LNG prices, coal-market conditions and supply disruptions—than by El Niño-related temperature changes alone. On this basis, it reiterates Outperform on Cheniere Energy and Market-Perform on Venture Global, seeing no negative El Niño-driven impact on LNG exporters.

Analysis framework

Bernstein first tests monthly Japanese LNG consumption against HDDs and CDDs, selecting HDDs as the useful weather input because they show the stronger correlation. It then simulates a warmer 2026–27 winter from the forecast RONI differential, converts the assumed HDD change into monthly consumption using the observed relationship, compares the seasonal result with the prior year, and scales the percentage effect to Asian LNG imports.

  Weather-driven LNG demand sensitivity analysis

  The report estimates how warmer winter conditions could affect LNG consumption and then translates the result into Asian and global LNG import demand.

  Monthly linear correlation of Japanese LNG consumption with heating degree days

  Bernstein uses the observed monthly relationship between HDDs and LNG consumption to model a Super El Niño scenario; CDDs are tested but found not to be correlated with consumption.

Asset mapping & comparison

• Cheniere Energy (LNG)

  Covered LNG exporter; Bernstein sees no negative impact from a Super El Niño and reiterates Outperform.

  Strengths

  The report’s LNG-demand conclusion supports the view that weather-driven demand erosion would be immaterial.

  Comparison

  Rated Outperform versus Market-Perform for Venture Global.

  Risks

  Lower international LNG prices if Russian pipeline gas returns to Europe, re-contracting risk beyond 2037, and permitting delays on future expansion projects.

• Venture Global (VG)

  Covered LNG exporter; Bernstein sees no negative impact from a Super El Niño and reiterates Market-Perform.

  Strengths

  The report does not expect El Niño-related demand weakness to be material for LNG exporters.

  Comparison

  Rated Market-Perform versus Outperform for Cheniere Energy.

  Risks

  Lower international gas-price margins, regulatory approval delays or construction overruns; upside could come from higher margins, additional-project execution and debottlenecking export capacity.

Impact & implications

Bernstein argues that a Super El Niño should not materially impair global LNG demand or LNG-exporter fundamentals. It views storage, relative fuel economics, LNG and coal prices, and supply disruptions as more consequential drivers of demand than the modeled weather effect.

Risks

• The analysis may understate differences in El Niño climate effects across Asian regions, country-specific import patterns, and the role of pipeline gas alongside LNG.
• For Cheniere, lower international LNG prices, re-contracting risk beyond 2037, and permitting delays on expansion projects could pressure the price target.
• For Venture Global, lower international gas-price margins, project-approval delays and construction overruns are downside risks.

What to watch

• NOAA El Niño temperature-outlook updates expected in October and December for Europe and North Asia.
• EU gas-storage levels, particularly whether they remain at the low end of five-year averages.
• JKM versus TTF pricing, as an Asian premium could redirect LNG cargoes to Asia.
• Asian import data for October and November as indicators of spot buying.
• Asian coal-price disruptions, Qatari supply and tanker movements amid Strait of Hormuz conflict, and LNG freight rates from the Gulf Coast to Tokyo versus Rotterdam.
• EU energy-policy developments and the timing of Europe’s transition away from Russian gas.
