UPDATE 1-US natural gas futures fall 3% on lower demand forecast

Speculators increased net short positions to highest since April 2024, CFTC data shows

LSEG reports U.S. gas output declined in May, reducing inventory surplus

LSEG forecasts lower demand this week, with LNG exports down due to plant maintenance

Adds closing prices

By Scott DiSavino

- U.S. natural gas futures slid about 3% on Monday on as demand forecasts for this week were revised lower.

Front-month gas futures for July delivery NGc1 on the New York Mercantile Exchange (NYMEX) fell 11.1 cents, or 3.4%, to settle at $3.179 per million British thermal units (mmBtu). On Friday, the contract closed at its highest price since February 6.

After futures gained 19% in May, speculators last week boosted their net short futures and options positions on the NYMEX and Intercontinental Exchange to their highest levels since April 2024, according to the U.S. Commodity Futures Trading Commission's Commitments of Traders report.

SUPPLY AND DEMAND

Financial group LSEG said average gas output in the U.S. Lower 48 states fell to 109.6 billion cubic feet per day (bcfd) in May, down from 109.8 bcfd in April and a monthly record high of 110.6 bcfd in December 2025.

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

But they noted recent output declines likely reduced the inventory surplus to around 5.9% above normal during the week ended May 29 from 6.2% above normal the previous week. EIA/GAS NGAS/POLL

Looking forward, meteorologists forecast mostly warmer-than-normal weather through June 16, which should boost demand for gas from power generators to keep air conditioners humming. About 40% of U.S. electricity generation comes from gas-fired power plants.

LSEG projected average gas demand in the Lower 48 states, including exports, would rise from 98.4 bcfd this week to 101.4 bcfd next week. The forecast for this week was lower than LSEG's outlook on Friday.

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