Price difference between Houston Ship Channel and Henry Hub in June was the smallest since 2021
In June 2023, the natural gas spot price at the Houston Ship Channel—a key regional trading hub for natural gas in East Texas averaged $2.14 per million British thermal units (MMBtu) and the U.S. benchmark Henry Hub averaged $2.19/MMBtu. This difference between the two prices was the smallest since September 2021, when the price at the Houston Ship Channel was $0.06/MMBtu lower than Henry Hub, on average. From the end of 2021 through the second half of 2022, the price differential widened significantly, with the price at the Houston Ship Channel reaching $1.27/MMBtu below the Henry Hub price on average in November. Several factors in the natural gas market contributed to the price at the Houston Ship Channel falling well below Henry Hub in 2022. Natural gas production in the Permian region set an annual record high in 2022 at 21.1 billion cubic feet per day (Bcf/d), 14% above the 2021 average, which followed a 9% increase in annual natural gas production in 2021, according to our Drilling Productivity Report. Natural gas production in the Eagle Ford region in Texas rose 14% (0.8 Bcf/d) in 2022. In 2021, more than 5.5 Bcf/d of new natural gas pipeline capacity entered service in Texas. The additional pipeline takeaway capacity improved producers’ ability to move natural gas from producing regions to consuming regions along the Gulf Coast. The shutdown of the El Paso Natural Gas Line 2000 pipeline from August 2021 through February 2023 resulted in reduced natural gas flows west from the Permian region to the Desert Southwest and California. During this period, new pipeline capacity out of the Permian region enabled an increase in flows of natural gas volumes southeast to the Gulf Coast. The June 2022 shutdown of the Freeport LNG export terminal, located south of Houston, reduced demand for natural gas deliveries to the terminal by 2.0 Bcf/d, resulting in an oversupply of natural gas in the East Texas markets. The difference between the Houston Ship Channel and Henry Hub price reached its widest negative differential on November 4, when the Houston Ship Channel price was $2.72/MMBtu lower than Henry Hub.After reaching a peak in August 2022, the Henry Hub price fell more slowly than the Houston Ship Channel price, which contributed to the differential reaching its widest point in November 2022. From August to November 2022, the Houston Ship Channel price fell 50% from an average of $8.20/MMBtu in August to an average of $4.10/MMBtu in November, whereas the Henry Hub price fell 39%, from $8.79/MMBtu in August to $5.37/MMBtu in November. The Henry Hub price declined more slowly, in part, because of continued strong demand for LNG exports through the end of 2022 and high utilization of Louisiana-based LNG export facilities.

Propane prices rose 4%, while the Brent crude oil price rose 3%, increasing the propane discount relative to crude oil by 2%. The normal butane price rose 3%, the isobutane price fell 4%, and the natural gasoline price rose 4%.
Supply and Demand
Supply: According to data from S&P Global Commodity Insights, the average total supply of natural gas rose by 0.3% (0.4 Bcf/d) week over week. Dry natural gas production grew by 0.3% (0.3 Bcf/d) to average 101.3 Bcf/d, while net imports from Canada were essentially unchanged from last week, averaging 6.1 Bcf/d. Demand: Total U.S. consumption of natural gas fell by 0.6% (0.4 Bcf/d) compared with the previous report week to average 75.9 Bcf/d, according to data from S&P Global Commodity Insights. Natural gas consumed for power generation declined by 1.2% (0.5 Bcf/d) week over week. In contrast, industrial sector consumption increased by 0.4% (0.1 Bcf/d), and the combined residential and commercial sector consumption increased by 0.4% (less than 0.1 Bcf/d) week over week. Natural gas exports to Mexico decreased 1.0% (0.1 Bcf/d) week over week to average 6.2 Bcf/d. Natural gas deliveries to U.S. LNG export facilities (LNG pipeline receipts) averaged 12.6 Bcf/d, essentially unchanged from last week.
Liquefied Natural Gas (LNG)
Pipeline receipts: Average natural gas deliveries to U.S. LNG export terminals were essentially unchanged week over week, averaging 12.6 Bcf/d, according to data from S&P Global Commodity Insights. Natural gas deliveries to terminals in South Texas decreased by 3.1% (0.1 Bcf/d) to 3.9 Bcf/d, while deliveries to terminals in South Louisiana increased by 2.6% (0.2 Bcf/d) to 7.5 Bcf/d. Natural gas deliveries to terminals outside the Gulf Coast decreased by 6.1% (0.1 Bcf/d), almost entirely due to a decline in deliveries to the Cove Point terminal in Maryland. TC Energy declared a force majeure on its Columbia Gas Transmission pipeline after an explosion occurred at a section of the pipeline near Strasburg, Virginia, on Tuesday, which decreased natural gas flows to the Cove Point LNG terminal. Vessels departing U.S. ports: Twenty-four LNG vessels (seven from Sabine Pass, four each from Cameron and Freeport, three each from Calcasieu Pass and Corpus Christi, two from Elba Island, and one from Cove Point) with a combined LNG-carrying capacity of 86 Bcf departed the United States between July 20 and July 26, according to shipping data provided by Bloomberg Finance, L.P.
Storage
Net injections into storage totaled 16 Bcf for the week ending July 21, compared with the five-year (2018–2022) average net injections of 31 Bcf and last year’s net injections of 18 Bcf during the same week. Working natural gas stocks totaled 2,987 Bcf, which is 345 Bcf (13%) more than the five-year average and 573 Bcf (24%) more than last year at this time. According to The Desk survey of natural gas analysts, estimates of the weekly net change to working natural gas stocks ranged from net injections of 6 Bcf to 31 Bcf, with a median estimate of 14 Bcf. The average rate of injections into storage is 4% higher than the five-year average so far in the refill season (April through October). If the rate of injections into storage matched the five-year average of 9.3 Bcf/d for the remainder of the refill season, the total inventory would be 3,940 Bcf on October 31, which is 345 Bcf higher than the five-year average of 3,595 Bcf for that time of year.
