Natural Gas Price and Chart

Natural gas: the Henry Hub price, what moves it and how to read the chart

Natural gas is the fuel that heats roughly half of American homes, generates a large share of the country's electricity and feeds a fast-growing export business shipping liquefied gas around the world. Of all the commodities you can chart, it may be the most temperamental: a cold front, a storage report or a single export terminal going offline can swing the price by double digits in a matter of days. This page gives you a live interactive chart for natural gas plus a technical-analysis summary, so you can watch the market and understand what's behind each move. It's built for reading and learning, not for placing trades.

In the United States the reference price is Henry Hub, a physical pipeline interchange in Erath, Louisiana, where several major interstate and intrastate pipelines meet. Because so much gas physically changes hands there, Henry Hub became the delivery point for the NYMEX natural gas futures contract (ticker NG), each one covering 10,000 million British thermal units, or MMBtu. When you see a U.S. gas price quoted in dollars per MMBtu, it's almost always Henry Hub. Europe and Asia have their own benchmarks, such as the Dutch TTF, but Henry Hub is the number that anchors North American trading.

What actually drives the price

Weather is the headline driver. About 48% of U.S. households heat with natural gas, so a cold winter pulls demand sharply higher, while summer heatwaves push gas-fired power plants harder to run air conditioning. A single polar vortex can spike prices 30 to 50% in days as utilities scramble for supply and storage drains faster than expected. Mild shoulder seasons in spring and autumn do the opposite, leaving the market well supplied and prices soft.

Storage is the weekly scorecard. Gas is injected into underground storage during the low-demand summer and withdrawn through winter. Every Thursday the U.S. Energy Information Administration publishes inventory levels, and the market reacts instantly to how they compare with the five-year average. Inventories well above average usually mean lower prices; levels at or below average signal a tight market and lift prices. This single report is often the biggest short-term catalyst of the week.

Production sets the floor. Most U.S. supply now comes from shale, dominated by the Marcellus and Utica plays in Appalachia and the Haynesville in Louisiana and Texas. Rig counts and drilling activity in these basins are leading indicators: when producers add rigs, more supply is on the way; when they pull back, the market tightens. Pipeline outages and freeze-offs, where wellheads literally freeze in extreme cold, can cut output suddenly.

LNG exports link the U.S. to the world. Since the Sabine Pass terminal opened in 2016, the U.S. has become a major exporter of liquefied natural gas, with volumes now equal to a meaningful slice of domestic production. When European or Asian gas prices spike, more U.S. gas is liquefied and shipped abroad, tightening domestic supply and pulling Henry Hub higher. This growing export base has put a firmer floor under U.S. prices than existed a few years ago, and it ties American gas to events as distant as a cold snap in Asia or a supply scare in Europe. The same logic connects gas to crude oil, since the two compete and trade together across global energy markets.

Power switching balances the demand side. Utilities choose between coal and gas to generate electricity largely on price. When gas is cheap, generators switch from coal to gas, which adds demand and cushions the downside. When gas gets expensive, the flow reverses and coal claws back market share. This coal-to-gas switching acts like a built-in shock absorber on both ends of the price range.

Why natural gas is so volatile and seasonal

Two things make gas uniquely jumpy. First, it's hard and expensive to store compared with oil, so supply can't easily flex to meet a sudden demand spike. Second, demand is tightly bound to the weather, which is unpredictable. Put those together and you get a market that can stay quiet for months, then erupt. Prices are typically lower and calmer in summer, when injection-season storage builds, and higher and far more volatile in winter, when a cold forecast can trigger record withdrawals. In early 2026, for example, a polar vortex and heavy storage draws pushed prices toward $7/MMBtu before they settled back. That seasonal rhythm, calm summers and stormy winters, is the defining feature of the gas chart.

How to read the natural gas chart

The chart above plots price over time, usually as candlesticks. Each candle shows the open, close, high and low for its period; the body is the open-to-close range and the thin wicks mark the extremes. A run of higher highs and higher lows points to an uptrend, the reverse points down, and a sideways drift means the market is undecided. A moving average smooths the noise into one line, and support and resistance levels mark prices where buyers or sellers have repeatedly stepped in. Switch timeframes to match your question: an intraday view captures a storage-report reaction, while a multi-year view reveals the seasonal pattern clearly. Remember that indicators describe what has already happened rather than predicting what comes next.
