Henry Hub Natural Gas Futures (NG): Contract Specs, Tick Value and Margins

What Are Henry Hub Natural Gas Futures (NG)?

Henry Hub Natural Gas futures (NG) are the standard natural gas contract on NYMEX, part of CME Group. Each contract covers 10,000 million British thermal units (MMBtu) for delivery at the Sabine Pipe Line Henry Hub in Erath, Louisiana, a junction where many interstate and intrastate pipelines meet. Because so much gas changes hands there, the NG price is the reference most U.S. natural gas contracts and price reports are quoted against.

NG is quoted in dollars per MMBtu, moves in $0.001 increments worth $10.00 per contract, and trades on CME Globex for about 23 hours each weekday. CME Group also lists two cash settled versions: E-mini Natural Gas (QG) at one quarter of the size and Micro Henry Hub Natural Gas (MNG) at one tenth.

How Much Is One Tick in Natural Gas Futures Worth?

NG prices move in increments of $0.001 per MMBtu, a tenth of a cent. Multiplied by the 10,000 MMBtu in each contract, one tick changes the value of an NG position by $10, and a one cent move ($0.01) equals $100.

10,000 MMBtu × $0.001 = $10 per tick

Lincoln Park Financial lists the NG day trading margin for positions opened and closed during the intraday session. An NG position still open after the session must meet the overnight margin, which follows the NYMEX requirement and is much higher because natural gas can gap when the market reopens or after the weekly storage report.

What Moves Henry Hub Natural Gas Prices?

Natural gas is one of the more volatile futures markets. The factors below are the ones NG traders follow most closely; they describe how the market is analyzed, not where prices will go.

  • Weather: heating demand in winter and power plant demand for air conditioning in summer drive U.S. consumption. Traders track heating and cooling degree days and the NOAA 6 to 10 day and 8 to 14 day temperature outlooks.
  • Storage: the U.S. Energy Information Administration (EIA) Weekly Natural Gas Storage Report, released Thursdays at 9:30 a.m. CT, shows the change in gas held underground. Traders compare it with the prior week, the five year average and survey estimates.
  • Production: output from shale regions such as Appalachia, the Permian Basin and the Haynesville sets how much supply reaches the market, and rig counts are watched as a signal of future drilling activity.
  • LNG exports: Gulf Coast liquefied natural gas terminals draw large volumes of U.S. gas for export, so plant outages, maintenance and new export capacity affect demand at Henry Hub.
  • Infrastructure and hurricanes: pipeline constraints and Gulf of Mexico storms can disrupt production, processing or LNG shipments.

Futures trading involves substantial risk of loss, and natural gas can move several percent in a single session.
