Natural-gas prices ended lower after a strong start Monday, with analysts saying near-term weather forecasts are still too warm to overcome record supply. The front-month January contract settled down 7.6 cents, or 2%, at $3.719 a million British thermal units on the New York Mercantile Exchange. Prices started the session immediately higher, opening at $3.843/mmBtu, and then steadily retreated, losing 3.2% between the open Sunday evening and the close Monday afternoon. The U.S. oil and gas boom has led to record supply outpacing growth in demand. Demand is largely dependent on home heating, and weather forecasters are still expecting above-normal temperatures through Christmas. That has traders expecting supply to keep outpacing demand, driving prices down, analysts said. –Write to Timothy Puko at [email protected]
