What it is
Henry Hub is the benchmark price for natural gas in the United States, named after a pipeline hub in Erath, Louisiana, where multiple interstate and intrastate pipelines converge. It is priced in dollars per million British Thermal Units (MMBtu). Natural gas is used as a heating fuel, an industrial process fuel (chemicals, fertilizers, glass, paper), and increasingly as a feedstock for electricity generation.
Who publishes it
Natural gas futures are traded on the New York Mercantile Exchange (NYMEX). The spot price at Henry Hub is also reported by the US Energy Information Administration (EIA), a division of the Department of Energy, which publishes weekly natural gas storage and production data that significantly drives price moves.
Update frequency
Futures prices update daily. Weekly EIA storage reports (released every Thursday morning) frequently cause notable price swings and are worth watching during periods of high price volatility.
Typical price range
Historically ranging from under $2 to over $9 per MMBtu. It is one of the most volatile commodities in this report, capable of doubling or halving within a single season depending on weather, storage levels, and export demand.
What a move means for planning
Natural gas is a direct cost driver for utilities, process manufacturing, fertilizer economics, and facility operations. For companies running energy-intensive facilities (food processing, chemicals, glass, steel, paper, and others), a sustained rise in natural gas prices directly compresses operating margins. It also flows into electricity generation costs, meaning even non-manufacturing businesses see utility cost pressure when gas prices spike. In agriculture, natural gas is a critical input for nitrogen fertilizer production, so gas price moves ripple into crop input costs and food prices. For budget planning: a gas price that has risen significantly from the prior year's average warrants a line-item review of utility and process energy assumptions.
