Nat-Gas Prices Pressured by Cooling Summer Weather and Abundant US Supplies

September Nymex natural gas prices settled lower, hitting a 9.25-month low, primarily driven by bearish supply-demand dynamics. Cooler weather forecasts for late August are expected to curb demand from electricity providers, while US natural gas production remains near record highs, with the EIA raising its 2025 and 2026 output forecasts. Despite a year-over-year increase in US electricity output, ample domestic inventories, currently 6.6% above their five-year seasonal average, continue to exert significant downward pressure, signaling an oversupplied market.

Analysis

September Nymex natural gas futures (NGU25) have declined to a 9.25-month low, driven by a fundamentally bearish supply and demand outlook. Downward pressure stems from forecasts for cooler US weather from August 25-29, which is expected to curb gas demand from electricity providers. This is compounded by robust domestic production, with Lower-48 dry gas output running at 107.5 bcf/day, a 5.2% year-over-year increase. The supply glut is reinforced by the EIA's recent upward revisions to its 2025 and 2026 production forecasts. While certain metrics appear supportive, such as a 7.1% year-over-year rise in electricity output and a consensus for a smaller-than-average weekly inventory build of +18 bcf, they are overshadowed by key bearish indicators. US natural gas inventories stand 6.6% above their 5-year seasonal average, signaling ample supply, and a 7.4% week-over-week drop in LNG net flows to export terminals further limits offtake for domestic gas.

Key Decisions for Investors

• Given the confluence of high production, inventories sitting 6.6% above the five-year average, and a weakening near-term demand outlook, investors should maintain a cautious to bearish stance on natural gas prices.
• Monitor the upcoming weekly EIA inventory report closely; a build significantly below the +18 bcf consensus could provide a short-term price floor, but the fundamental oversupply is likely to cap any sustained rally.
• Pay close attention to weekly LNG export flow data, as the current 7.4% week-over-week decline is a key bearish factor, and a reversal could signal strengthening external demand that would help absorb domestic supply.
• While the European gas storage deficit represents a potential longer-term bullish catalyst, its current impact is muted, and investors should weigh it against the more immediate and dominant factors of high US production and comfortable domestic storage levels.
