At a glance

  • Henry Hub futures volume grew exponentially in H1 2020 on a year-on-year basis, with trading during non-US hours rising.
  • CME Group price spreads during non-US trading hours were nearly as tight as during US trading hours, signalling the ample liquidity traders need to readily execute trades.

The COVID-19 pandemic led to a sharp reduction in demand for natural gas in the first half of 2020 as major consumer nations went into lockdown, leading to a sharp fall in the price of CME benchmark Henry Hub futures. 

The differing pace of economic recovery around the world, added to the impact on production of the US hurricane season, as well as the usual uncertainty around the severity of the upcoming northern hemisphere winter, have all combined to generate significant price volatility in the natural gas markets.

Market participants looking to manage this price risk turned to Henry Hub futures, which saw volume increase by 37% year-over-year by the end of July 2020.

Henry Hub volumes rise

The Henry Hub futures contract reached a peak in average daily volume (ADV) in Q1 2020. Volumes remained elevated relative to the prior year through Q2 and into July, and they were up 37% year-over-year.

As volumes grew in the first half of the year, there was a clear upward trend in non-US trading hours (5 p.m. – 7 a.m. CT). This underscores the growing international relevance of Henry Hub, with non-US volume growing by more than 50% year-over-year each month in the first half of the year.

Non-US trading hour spreads

As volumes in non-US trading hours increased, spreads during these hours remained very close to the tight spreads seen during US trading hours. This remained the case even during April 2020, when spreads during non-US hours widened slightly. Throughout Q2, US spreads remained fairly steady. Though non-US spreads were slightly elevated, they remained below 1.5 ticks on average.

This liquidity is crucial to ensuring global market participants can trade readily during their local time zones. With volumes increasing and spreads remaining tight, it’s clear that international traders are finding sufficient liquidity in Henry Hub to execute their strategies.
