Corpus Christi Stage 3 Advances as JKM-Henry Hub Spread Reaches $20 Per MMBtu
A $20 Asian-US gas arbitrage is accelerating Corpus Christi expansion and drawing pipeline capacity away from domestic markets, with consequences for PJM power pricing.
JKM Asian LNG spot prices stood at $23.41 per MMBtu on Friday (2026-08-28), roughly $20 above NYMEX Henry Hub front-month gas at $2.89 per MMBtu. That spread drives the calculus for US supply chain investment, stretching from Gulf Coast pipeline corridors to PJM's gas-fired generation fleet.6,7
Every cubic foot reaching a US liquefaction terminal is worth multiples of its domestic value at that differential. Corpus Christi Stage 3, Cheniere Energy's next major expansion, was the focal point of that calculus as of Wednesday (2026-08-19), with Kalkinemedia reporting that operational focus at the complex was "squarely on execution."7
EIA data show the US could add 44.9 billion cubic feet per day of pipeline capacity during 2026-27, with 31.6 billion cubic feet per day already under construction, according to RBAC Inc.'s analysis published on August 10 (2026-08-10). About 29.7 billion cubic feet per day originates from Texas production; another 8.4 billion cubic feet per day from Louisiana.6
The recently completed Matterhorn Express, a 580-mile pipeline, added 2.5 billion cubic feet per day of Permian Basin takeaway capacity, routing gas to the Katy Hub near Houston and onward to Gulf Coast export terminals including Corpus Christi. RBAC's second-quarter 2026 base case projects US LNG exports more than doubling, from 14.9 billion cubic feet per day in 2025 to 32.4 billion cubic feet per day by 2035.6
The US has established itself as the dominant swing exporter. Forbes reported on July 19 (2026-07-19) that the US supplied 93% of global LNG export growth in 2025, reflecting combined volumes from Sabine Pass, Corpus Christi, and newer additions. Golden Pass LNG, which EIA counted as the ninth US liquefaction terminal, shipped its first cargo on April 22, 2026, adding further draw on domestic gas supply.3,2
US LNG exports are forecast to average around 17 billion cubic feet per day across 2026, with volumes expected to rise in 2027 as projects that reached final investment decision during 2025, representing more than 2.8 trillion cubic feet of annual capacity, begin operations, according to Forbes and OilPrice.com.3,4
The supply chain pressure extends beyond the Gulf Coast. PJM Western Hub real-time power was at $73.72 per megawatt-hour on Friday (2026-08-28), and market signals in the region carry a bearish weight — traders appear to see current power prices as elevated relative to near-term fundamentals. Gas-fired generation in PJM draws on Henry Hub-linked supply; as LNG export pull competes for domestic gas volumes, the floor under East Coast generator fuel costs becomes harder to read from hub pricing alone.6
Japanese utility JERA, whose portfolio includes medium- and long-term offtake from US terminals, noted in its July 2026 integrated report that its LNG strategy relies on flexible optimization through JERA Global Markets alongside its own tanker fleet. The organized durability of that buy-side demand reinforces the commercial case for accelerating US export capacity.5
ICE Endex TTF front-month European gas was flat at €68.01 per megawatt-hour on Friday (2026-08-28), maintaining the Atlantic LNG arbitrage and ensuring US gas loaded, liquefied, and shipped to Europe still commands a significant margin over the cost of production and transport. That differential underpins the capital discipline now visible across Gulf Coast operators, where larger players are focused on efficiency and long-term returns rather than the aggressive volume growth that characterized the early shale era.1,7
Whether Corpus Christi Stage 3 holds its construction schedule is the signal most worth tracking in coming months. Any slip in mechanical completion delays the volume growth embedded in RBAC's 32.4 billion cubic feet per day forecast, leaves offtake commitments without backing, and tests the tolerance of structured buyers like JERA, who have organized their portfolios around US supply timelines.6,5,7
