U.S. natural gas market just saw some notable tightening—the 12-month forward spread compressed by $0.33, marking a sharp 72% pullback. Here's what happened: February contracts jumped $0.21 (6%) to hit $3.88 in the week through December 26, while the spot month rallied even harder, climbing $0.38 from $3.98 to $4.37. The narrowing spread signals shifting market expectations around supply dynamics. When front-month prices surge like this while longer-term contracts stay relatively anchored, it often reflects supply concerns or demand strength in the immediate term. Worth watching how these spreads evolve as weather and production data roll in.
