Nat-Gas Prices Erase Early Gains as US Weather Forecasts Cool

September Nymex natural gas (NGU25) prices closed down -0.32% on Thursday, reversing earlier gains, as cooler US weather forecasts tempered demand expectations despite a bullish EIA report showing a smaller-than-anticipated +7 bcf inventory build. While the inventory data was supportive, robust US dry gas production at 108.7 bcf/day (+5.7% y/y), a two-year high in active drilling rigs, and increased LNG export flows underscore a well-supplied market, ultimately weighing on prices.

Analysis

September Nymex natural gas (NGU25) futures displayed significant intra-day volatility, closing down 0.32% after initially reaching a one-week high. The market is weighing conflicting fundamental signals, with bearish supply and demand factors ultimately overpowering a bullish inventory report. The primary catalyst for the price decline was a cooler weather forecast from Vaisala for the eastern US, which is expected to curb near-term demand from electricity providers. This is compounded by a fundamentally weak domestic demand picture, with Lower-48 state gas demand reported at 78 bcf/day, a 2.8% year-over-year decrease. On the supply side, persistent headwinds remain, evidenced by robust dry gas production of 108.7 bcf/day (+5.7% y/y) and a Baker Hughes report showing active gas rigs climbing to a two-year high of 124. The bullish surprise came from the weekly EIA data, which showed an inventory build of only +7 bcf, well below the +12 bcf consensus and the +29 bcf five-year average. While this tightened the year-over-year inventory deficit to -4.3%, total stockpiles remain 5.9% above the five-year average, signaling adequate supply. Strong LNG export flows, up 10.1% week-over-week, provided some support but were insufficient to sustain the initial price rally.

Key Decisions for Investors

• Investors should closely monitor US dry gas production figures and the Baker Hughes rig count, as the current trend towards a two-year high in drilling activity suggests a persistent supply-side headwind for prices.
• The market's negative reaction to cooler weather forecasts, despite a bullish EIA inventory report, indicates that short-term demand expectations are a primary price driver, making upcoming weather model updates a critical variable to watch.
• Given that US inventories remain 5.9% above the five-year average, the market appears well-supplied, suggesting that sustained price rallies may require either a significant disruption to production or a substantial, unexpected increase in demand from weather or LNG exports.
