Nat-Gas Prices Supported by Warm US Weather

October Nymex natural gas prices saw a marginal increase on Wednesday, primarily supported by forecasts for warmer US weather expected to boost electricity demand for air conditioning. However, this upward pressure is significantly tempered by ample US natural gas supplies, which are 6.3% above their five-year seasonal average, and near-record high production, with the EIA recently raising its 2025 output forecast, signaling a persistent bearish supply outlook.

Analysis

October Nymex natural gas futures (NGV25) are exhibiting a classic conflict between short-term demand drivers and long-term supply fundamentals, resulting in a marginal price increase of 0.18%. The primary bullish catalyst is a forecast for warmer US weather from September 29 to October 8, which is expected to increase gas demand from electricity providers for cooling. This demand is corroborated by a 2.3% year-over-year rise in US electricity output for the week ending September 20. However, these factors are heavily counteracted by a significant supply overhang. US natural gas inventories as of September 12 stood 6.3% above their 5-year seasonal average, signaling abundant supply. This is compounded by robust production, with lower-48 dry gas output at 108.0 bcf/day, a 5.6% year-over-year increase, and the EIA raising its 2025 production forecast. The bearish sentiment was reinforced by the previous week's larger-than-expected inventory build of +90 bcf, while the upcoming report's consensus build of +74 bcf is only slightly below the five-year average, offering limited support.

Key Decisions for Investors

• Investors should view the current price support as likely short-lived, as it is driven by a temporary weather forecast, while the fundamental backdrop of near-record production and inventories 6.3% above the 5-year average remains decidedly bearish.
• Closely monitor the weekly EIA natural gas inventory report; a build coming in significantly below the +74 bcf consensus would be required to signal a meaningful tightening of the market balance and challenge the prevailing oversupply narrative.
• Given the structural oversupply in the US, traders should watch for any significant increase in LNG export flows, as stronger international demand, potentially driven by Europe's below-average storage levels, represents a key potential catalyst for a sustained price increase.
