Natural Gas

About Natural Gas

Natural gas is the world’s third-most consumed energy source after oil and coal, and the cleanest-burning fossil fuel. It is used extensively for electricity generation, residential and commercial heating, industrial processes, and increasingly as a feedstock for petrochemicals. The primary US natural gas benchmark, Henry Hub, is priced in US dollars per million British Thermal Units (MMBtu) and traded on the NYMEX. Natural gas markets have undergone a dramatic transformation with the rise of US shale production (which has made the US the world’s largest producer), the growth of liquefied natural gas (LNG) trade, and natural gas’s emerging role as a “transition fuel” in the shift from coal to renewables. Natural gas prices are among the most volatile in the commodity complex, with seasonal demand patterns and weather events creating extreme price swings.

What Moves Natural Gas Prices?

Weather and Seasonal Demand

Weather is the single most important short-term driver of natural gas prices. Cold winter temperatures increase heating demand, while hot summer temperatures boost electricity demand for air conditioning (gas-fired power plants). The US heating degree days and cooling degree days data, NOAA weather forecasts, and seasonal weather patterns create a powerful demand cycle. Polar vortex events and unusual heat waves can cause dramatic price spikes.

Storage Levels

The EIA Weekly Natural Gas Storage Report, released every Thursday at 10:30 ET, is the most closely watched data point for natural gas traders. The report shows whether gas in underground storage facilities was injected (built up during mild weather) or withdrawn (drawn down during high demand). Deviations from expectations can cause immediate price reactions. Storage levels relative to the five-year average indicate whether the market is oversupplied or undersupplied heading into peak demand seasons.

US Production and Shale Output

US natural gas production, driven primarily by shale basins like the Marcellus, Haynesville, and Permian (associated gas from oil drilling), determines domestic supply availability. Drilling rig counts, production estimates, and pipeline capacity constraints influence the supply outlook. Changes in oil drilling activity affect associated gas production, creating an indirect link between oil and natural gas markets.

LNG Exports and Global Demand

The growth of US LNG export capacity has connected the previously isolated US gas market to global pricing. European and Asian gas demand, LNG shipping rates, and international price differentials (JKM in Asia, TTF in Europe) now influence Henry Hub prices. Geopolitical events affecting global gas supply, such as disruptions to Russian pipeline gas deliveries to Europe, have increased the international demand pull on US gas.

Trading Natural Gas

Natural gas futures are traded on NYMEX (NG contract, 10,000 MMBtu per contract), with Micro Natural Gas contracts, ETFs (UNG), options, and CFDs also available. Natural gas is among the most volatile major commodities, with daily moves of 3-5% being common and 10%+ swings possible during extreme weather events. Peak trading activity occurs during US hours, particularly around the weekly storage report. Natural gas trading requires an understanding of seasonal patterns (injection season vs withdrawal season), weather forecasting, and the futures curve structure. The commodity is not for the faint-hearted, as its extreme volatility can generate large profits or losses in short periods.
