UPDATE 1-US natgas prices end at 16-week high after 19% rally in May

Adds latest prices

Warmer weather boosts air conditioning demand, supporting higher natural gas prices

LSEG reports U.S. gas output dips in May, LNG exports fall due to plant maintenance

Only one of five U.S. LNG vessels still heading to China

By Scott DiSavino

- U.S. natural gas futures closed out a month-long rally to end at a 16-week high on Friday on forecasts for warmer weather and more air conditioning demand over the next two weeks than previously expected.

Front-month gas futures for July delivery NGc1 on the New York Mercantile Exchange rose 0.5 cent, or 0.2%, to settle at $3.29 per million British thermal units (mmBtu), the highest close since February 6.

For the month, the contract gained 19%. It rose 13% on the week after sliding about 2% last week.

SUPPLY AND DEMAND

Financial group LSEG said average gas output in the U.S. Lower 48 states fell to 109.5 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.

Meteorologists forecast mostly warmer-than-normal weather through June 13, which should boost the amount of gas power generators burn to keep air conditioners humming. About 40% of U.S. generation comes from gas-fired power plants.

LSEG projected average gas demand in the Lower 48 states, including exports, would slide from 100.3 bcfd this week to 99.0 bcfd next week before rising to 101.5 bcfd in two weeks. The forecasts for this week and next were similar to LSEG's outlook on Thursday.

LNG FEEDGAS DOWN

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 17.1 bcfd so far in May due to spring maintenance at several plants, including ExxonMobil/QatarEnergy's Golden Pass and Freeport LNG's plant in Texas.

There is now only one vessel going directly from the U.S. to China, the Al Sene, which left Venture Global's VG.N Plaquemines plant in Louisiana in mid-May and is expected to reach China in late June. That is down from as many as five vessels over the prior week or so.

No LNG tanker has left a U.S. export plant and gone directly to China during U.S. President Donald Trump's second term, which started in January 2025, due primarily to trade disputes between the world's two biggest economies.

China, which imported lots of U.S. gas in the past and has many contracts to buy U.S. LNG, is the world's biggest gas importer, while the United States is the world's biggest gas producer, consumer and exporter. Chinese companies have sold the U.S. LNG they buy in other countries.
