UPDATE 1-US natgas prices hit one-week low on forecasts of lower demand, rising output

Adds latest prices

Mild weather, high storage levels reduce demand and ease price pressure

LNG export plant maintenance, including at Freeport and Golden Pass facilities, limits feedgas flows

LSEG projects lower gas demand next week despite warmer-than-normal weather

By Scott DiSavino

- U.S. natural gas futures slid about 3% to a one-week low on Monday on forecasts for less demand next week than previously expected, a small output increase and lingering maintenance at liquefied natural gas (LNG) export plants.

Front-month gas futures for July delivery NGc1 on the New York Mercantile Exchange fell 8.2 cents, or 2.5%, to settle at $3.147 per million British thermal units (mmBtu), their lowest close since May 27.

That price decline occurred even though Freeport LNG's export plant in Texas was on track to take in more gas on Monday after one of its three liquefaction trains had shut down on Saturday.

Financial group LSEG said average gas output in the U.S. Lower 48 states has slid to 109.5 billion cubic feet per day (bcfd) so far in June, down from 109.7 bcfd in May and a monthly record high of 110.6 bcfd in December 2025. Average output so far in June, however, was higher than last week.

AMPLE AMOUNTS OF GAS IN STORAGE

Analysts said mild weather during the spring allowed energy firms to stockpile more gas than usual.

But they noted recent output declines likely reduced the surplus of gas in inventory to around 5% above normal during the week ended June 5, down from about 6% above normal in the previous week. EIA/GAS NGAS/POLL

Meteorologists forecast the weather will remain mostly warmer than normal through June 23, which should boost the amount of gas that power generators burn to keep air conditioners humming. About 40% of U.S. power generation comes from gas-fired plants.

LSEG projected average gas demand in the Lower 48 states, including exports, would rise from 102.7 bcfd this week to 103.3 bcfd next week. The forecast for this week was higher than LSEG's outlook on Friday, while its forecast for next week was lower.

Average gas flows to the nine big U.S. LNG export plants fell from 17.1 bcfd in May to 16.3 bcfd so far in June due to ongoing spring maintenance at several plants, including ExxonMobil XOM.N/QatarEnergy's Golden Pass facility and Freeport LNG's plant in Texas.

Those flows compare with a monthly LNG feedgas record high of 18.8 bcfd in April.
