UPDATE 1-US natural gas futures hover near one-week low as demand outlook slips

Spot prices at Waha Hub remain negative for record 76 days due to pipeline constraints

Lower 48 gas output down in May, storage surplus seen narrowing to 6% above normal

LSEG forecasts higher demand this week, but lower demand next week amid mild weather

Adds latest prices

By Scott DiSavino

- U.S. natural gas futures held near a one-week low on Tuesday after the long U.S. Memorial Day holiday weekend on forecasts for less demand next week than previously expected.

On its second-to-last day as the front-month, gas futures for June delivery NGc1 on the New York Mercantile Exchange fell 1.3 cents, or 0.4%, to settle at $2.894 per million British thermal units (mmBtu), their lowest close since May 14 for a second day in a row.

Futures for July NGN26, which will soon be the front-month, were also little changed at around $3.01 per mmBtu.

Looking forward, the 12-month NG12Mst and year-ahead NGYstc1 futures strips both fell to their lowest since December 2024.

In the cash market, average gas prices at the Waha Hub NG-WAH-WTX-SNL in West Texas have remained in negative territory for a record 76 days in a row as pipeline constraints trap gas in the Permian region, the nation's biggest oil-producing shale basin.

In the West, mild weather and ample hydropower supplies pushed spot power prices at South Path 15 W-SP15-IDX in Southern California into negative territory for the 12th time this year.

SUPPLY AND DEMAND

Financial group LSEG said average gas output in the U.S. Lower 48 states fell to 109.4 billion cubic feet per day (bcfd) so far in May, down from 109.8 bcfd in April and a monthly record high of 110.6 bcfd in December 2025.

Analysts said mild weather earlier this spring allowed energy firms to inject more gas into storage than usual.

But they noted recent output declines coupled with higher demand in recent weeks likely reduced the inventory surplus to around 6% above normal during the week ended May 22, down from roughly 7% above normal during the week ended May 15. EIA/GAS NGAS/POLL

Looking forward, meteorologists forecast the weather will remain mostly near normal through June 10.

LSEG projected average gas demand in the Lower 48 states, including exports, would slide from 99.7 bcfd this week to 98.3 bcfd next week. The forecast for this week was higher than LSEG's outlook on Friday, while the forecast for next week was lower.

Average gas flows to the nine big U.S. LNG export plants fell from a monthly record high of 18.8 bcfd in April to 17.0 bcfd so far in May due to spring maintenance at several plants, including ExxonMobil XOM.N/QatarEnergy's Golden Pass and Freeport LNG's plant in Texas.
