Natural gas prices have fallen sharply over the past month, catching many energy investors off guard.
The US natural gas benchmark is now trading near US$3.10 per MMBtu, down roughly 22% over the last 4 weeks. That move has pushed prices to their lowest levels in around 3 months and marks a swift reversal from the strength seen late last year.
So, what is happening, and what does it mean for ASX energy stocks?

Why natural gas prices are falling
The main driver behind the recent sell-off has been weaker demand.
Much of the US and Europe has experienced milder than normal winter weather, reducing heating demand during what is usually the strongest period of the year for natural gas consumption. That has left the market with less urgency to push prices higher.
US gas production continues to run near record levels, while storage withdrawals have come in well below expectations. The latest data showed inventories falling by just 71 billion cubic feet, well short of what the market had been expecting. As a result, storage levels remain comfortable, easing near-term supply concerns.
There has also been some softness on the export side. LNG feedgas flows have dipped in recent weeks as maintenance activity at export terminals reduced demand, adding to the short-term supply-demand imbalance.
What the outlook looks like
In the short term, many analysts expect natural gas prices to remain under pressure if mild weather continues and supply stays elevated.
Forecasts suggest global gas demand could pick up again in late 2026 and into 2027, supported by rising LNG exports, growing data centre power needs, and ongoing electrification. Some projections point to tighter market conditions next year if demand growth begins to outpace supply.
What this means for ASX energy stocks
For Australian energy companies, falling gas prices can be both positive and negative.
For Origin Energy Ltd (ASX: ORG), lower gas and LNG prices can pressure earnings from its LNG exposure, particularly through the Australia Pacific LNG project. At the same time, cheaper gas can help reduce input costs for its retail energy business.
For AGL Energy Ltd (ASX: AGL), lower wholesale gas prices can support margins for electricity generation and retail supply. However, softer energy prices can also limit revenue growth, especially in a competitive retail market.
Both companies are also influenced by domestic policy settings, including efforts to keep more gas available for local use, which can cap pricing power.
Foolish bottom line
Natural gas prices have fallen by around 22% over the past month due to weaker demand and ample supply. While that creates short-term pressure, longer-term demand trends suggest the market could tighten again.
Keep in mind that energy stocks remain exposed to swings in gas prices and weather patterns, making the sector one to watch closely in 2026.
