Natural Gas Prices Ease as Storage Build Beats Expectations

Today Markets Analysis: US natural gas futures edged lower on Friday as a larger-than-expected weekly storage build reinforced concerns over adequate supply, although persistent heat across parts of the United States and strong electricity demand continue to provide underlying support.

October Nymex natural gas futures (NGV26) closed 0.003 lower, or 0.11%.

The latest developments are being closely monitored by Today Markets, with additional currency and cross-market analysis available through Currency Hedger, both part of the Octalas Group.

EIA Storage Build Weighs on Prices

Natural gas prices came under pressure following Thursday’s weekly EIA storage report, which showed US inventories increasing by 40 Bcf during the week ending September 4.

The build exceeded the market expectation of 34 Bcf, reinforcing concerns that US natural gas supplies remain comfortable heading into the autumn shoulder season.

However, the increase remained below the five-year seasonal average build of 52 Bcf, preventing the report from being entirely bearish.

As of September 4, US natural gas inventories were 2.7% below year-ago levels, but 4.8% above the five-year seasonal average.

The inventory position therefore points to adequate overall supply, although the year-on-year deficit provides some underlying support.

Warm Weather Supports Electricity Demand

Weather remains an important near-term bullish factor.

The Commodity Weather Group expects above-normal temperatures across the South and Southeast through September 20, potentially increasing natural gas demand from power generators as air-conditioning requirements remain elevated.

Strong electricity consumption is already supporting gas-fired power generation.

The Edison Electric Institute reported Thursday that US lower-48 electricity output during the week ending September 5 increased 19.69% year-on-year to 100,302 GWh.

Electricity generation over the preceding 52 weeks also increased 3.00% year-on-year to 4,392,478 GWh.

The combination of elevated temperatures and stronger electricity consumption is therefore providing an important offset to the bearish storage picture.

US Gas Production Remains Elevated

Supply continues to represent a major headwind for natural gas prices.

According to BNEF, US lower-48 dry natural gas production was running at approximately 113.8 Bcf/day, up 4.4% year-on-year.

Lower-48 gas demand stood at 75.8 Bcf/day, an increase of 7.5% year-on-year.

Meanwhile, estimated net flows to US LNG export terminals reached 19.8 Bcf/day, up 1.5% week-on-week.

Strong production combined with robust LNG demand is keeping the US market well supplied, although continued LNG exports are helping absorb a portion of the country’s growing gas output.

Super El Niño Could Weigh on Winter Demand

The medium-term outlook remains more challenging for natural gas bulls.

Market expectations for a potentially powerful “Super El Niño” could result in warmer-than-normal temperatures across the Northern Hemisphere during the autumn and winter.

If realised, warmer conditions would reduce heating demand for natural gas and potentially lead to further inventory accumulation.

This is particularly important because the market is already carrying above-average storage levels.

The EIA projected on August 11 that US natural gas inventories could reach approximately 3,985 Bcf by the end of October, which would represent the highest end-October storage level in a decade and approximately 5% above the five-year average.

EIA Raises Future Production Forecast

The supply outlook is also becoming increasingly bearish.

The EIA raised its estimate for US dry natural gas production in 2027 to 116.0 Bcf/day, compared with its previous July forecast of 115.3 Bcf/day.

Higher production capacity could keep downward pressure on prices if demand growth fails to keep pace with supply.

For a market already facing elevated storage, stronger production expectations represent a significant medium-term risk.

Europe Remains Below Seasonal Storage Levels

European gas storage provides a contrasting signal.

As of September 8, European storage facilities were approximately 67% full, compared with a five-year seasonal average of 84%.

The relatively low level of European inventories could provide some support to global LNG demand as the Northern Hemisphere moves toward winter.

However, the impact on US prices will depend heavily on LNG export utilisation and the relative price relationship between US gas and European benchmark markets.

This is one area where broader cross-market analysis from Currency Hedger can be useful, particularly when assessing the interaction between energy prices, currencies and international demand.

Natural Gas Rig Count Near Three-Year High

Baker Hughes reported Friday that the number of active US natural gas drilling rigs increased by two to 132 rigs during the week ending September 11.

The total is only slightly below the three-year high of 134 rigs recorded in February 2026.

The continued strength in drilling activity suggests US producers remain confident in the longer-term economics of natural gas production, adding another potential source of supply growth.

Today Markets View

The natural gas market remains caught between strong short-term demand and comfortable medium-term supply.

Warm temperatures, rising electricity generation and relatively low European storage are providing support, while US production growth, above-average domestic inventories and the potential for a strong El Niño create significant downside risks.

The key issue for the market is whether elevated power-sector demand can continue absorbing increasing US production before the arrival of cooler weather.

Louis Roche, Analyst at Today Markets, commented:

“Natural gas is currently balancing two very different narratives. Near-term electricity demand remains strong, but the storage position and continued production growth suggest the market has little room for a significant deterioration in demand. The winter weather outlook will ultimately determine whether today’s comfortable supply position becomes a larger surplus.”

From a broader market perspective, Currency Hedger Contributor analysis also highlights the importance of watching energy markets alongside currency movements, particularly as changes in commodity prices can influence inflation expectations, interest-rate expectations and major currency pairs.
