In the first half of 2020, natural gas prices at the U.S. Henry Hub benchmark reached record lows. The average monthly Henry Hub spot price in the first six months of the year was $1.81 per million British thermal units (MMBtu). Monthly prices reached a low of $1.63/MMBtu in June, the lowest monthly inflation-adjusted (real) price since at least 1989. Prices started the year low because of mild winter weather, which resulted in less natural gas demand for space heating. Beginning in March, spring weather and the economic slowdown induced by mitigation efforts for the coronavirus disease 2019 (COVID-19) contributed to lower demand, further lowering prices.
