The recent joint U.S.-Israeli strike on Iran has added renewed volatility to global energy markets. While higher prices for crude oil and refined products are unsurprising, the implications for natural gas, particularly liquefied natural gas (LNG), are increasingly significant.
Qatar — one of the world’s top LNG suppliers — relies on shipments transiting the Strait of Hormuz. After insurance companies reportedly pulled coverage for tankers, some LNG vessels had to stop mid-route, and this disruption has caused global LNG prices to jump. In Europe, prices for April delivery on the Title Transfer Facility (TTF) surged about 38%, rising from $11.09 on Friday to $15.25 by Monday. As of March 1, European storage inventories stood near 30% full, with more withdrawals likely, pushing storage levels closer to lows seen during the COVID-19 period. Another challenge: The forward LNG price curve has once again inverted seasonally, with summer prices trading above the upcoming winter months, reducing the financial incentive for storage operators to refill inventories.
In the U.S., the near-term supply and demand balance remains largely unchanged. LNG export capacity is effectively maxed out, suggesting recent price strength reflects sympathetic movement with global energy markets rather than a fundamental domestic shift. Following the attack on Iran:
The more consequential impact of elevated global LNG prices may emerge during the winter period, particularly in the January-February 2027 contracts. Global LNG prices effectively establish the upper price threshold for U.S. Gulf Coast gas. In a very cold U.S. winter scenario, domestic prices sometimes must rise high enough to discourage LNG exports — and that threshold has now risen materially due to the increased risk of prolonged geopolitical conflict or damage to critical energy infrastructure involving Iran, Israel, and broader regional supply chains, including exports from Qatar.

The expiration of the prompt month (March 2026) natural gas contract was not without drama as the Chicago Mercantile Exchange ran into technical issues halting trading in the natural gas and metals contracts. Thirty days after the February 2026 natural gas contract settled at $7.46, the March 2026 contract expired at $2.969, down $4.49. This settlement reflects the change in trader sentiment moving from a very bullish posture 1 month ago to very bearish expectations. The market turnaround was primarily due to weather forecast projecting much cooler-than-normal temperatures that didn’t transpire and, in fact, verified warmer than normal.
March heating demand expectations have continued to fade as the likelihood of additional cold air intrusions across the U.S. diminishes. While March is technically a winter month, it remains a wildcard from a storage perspective, as it can register either net withdrawals or net injections:
Total U.S. natural gas inventories are currently estimated at 1.886 trillion cubic feet (Tcf), placing storage levels 115 Bcf above year-ago balances and 43 Bcf below the 5-year average. With the end of winter in sight, end-of-season storage is now projected to slightly above 1.8 Tcf, a meaningful increase from early February expectations that indicated ending balances below 1.6 Tcf. For reference, the 5-year average storage balance coming out of the winter is 1.81 Tcf, with a high balance of 2.27 Tcf in 2024, and a low balance of 1.396 Tcf in 2022.

Power prices have largely trended with natural gas, with the similar fundamental impacts of a mild February and concerns about the recent conflict in Iran.
PJM's updated 20-year load forecast confirms electricity demand across the region is growing at one of the fastest rates in its history, driven largely by data centers, electrification, and large commercial and industrial loads.
While PJM modestly reduced its near-term demand outlook through the early 2030s — due to improved vetting of large load requests — the long-term trajectory remains sharply higher, with summer peak demand expected to increase by roughly 85,000 megawatts (MW) over the next 15 years compared to last summer’s peak of roughly 160,000 MW.
This growth is already showing up in market outcomes: PJM’s most recent capacity auctions for the 2026-2027 delivery year cleared at the regulatory price ceiling of $329.17 MW/day, up 22% from the prior year and more than 10 times higher than prices seen just a few years ago. PJM has filed to keep the price ceiling and floor in place through May 2030. Given these forecasts and the delay in capacity auctions, it’s likely capacity prices could continue to hit the regulatory price ceiling.
Energy prices are also becoming more volatile as higher demand pushes the system closer to its operational limits during extreme weather:
As PJM projects continued long-term load growth without a corresponding pace of new dispatchable generation, these types of price spikes and elevated capacity costs are expected to become more frequent. For commercial customers, the forecast underscores growing exposure to higher peak period energy prices, rising capacity charges, and increased volatility — making proactive procurement, hedging, and load management strategies more important than ever.

February 2026 comes in as the 17th warmest nationally since 1950 based on gas-weighted heating degree days (HDDs). Despite some lingering cold at the start of the month, a majority of the U.S. managed to average above the 30-year normal, even to the tune of 10 degrees above normal in parts of the central U.S.
Colder temperatures did hold on along the eastern seaboard, and these states still managed to come in colder than the 30-year normal. In fact, the East EIA region finished as the 25th coldest since 1950 based on gas-weighted HDDs and the coldest in the region since 2015.
Winter 2025/2026 finished as the 25th warmest nationally since 1950 based on gas-weighted HDDs thanks to consistently well-above-normal temperatures in the West. Eastern regions experienced a few periods of notable cold, and areas from Ohio through the Northeast averaged 3 to 5 degrees below normal for the winter. For the East EIA region, this past winter was the 22nd coldest based on gas-weighted HDDs and the coldest since the winter of 2014/2015.
March 2026 is starting off well above normal across much of the country, with the first half of the month running as much as 10 to 15 degrees above normal in portions of the central and eastern U.S. Models are hinting at periods of cold in the second half of the month in the East, but such a strong warm start will make it difficult for temperatures to deviate from above-normal levels for the month as a whole.

Global energy markets have become more volatile following a joint U.S.-Israeli strike on Iran, which disrupted LNG shipping through the Strait of Hormuz and drove global LNG prices higher. While U.S. natural gas fundamentals remain largely unchanged due to LNG export capacity already operating at maximum levels, domestic prices rose modestly in response to global market movements and could face higher price ceilings in future winters if international LNG prices remain elevated.
Meanwhile, the U.S. natural gas market shifted sharply bearish as warmer-than-expected weather reduced heating demand. With March expected to be among the warmest on record, storage withdrawals are projected to be limited, leaving U.S. inventories closer to the 5-year average than earlier projections suggested.
Power prices have largely followed natural gas trends, influenced by a mild February and geopolitical concerns related to the conflict involving Iran. At the same time, electricity demand in the PJM region is projected to grow rapidly over the next two decades, driven by data centers, electrification, and expanding commercial and industrial loads. PJM forecasts summer peak demand could rise by about 85,000 MW over the next 15 years, and this tightening supply-demand balance is already reflected in capacity auctions clearing at the regulatory price cap for the 2026-2027 delivery year. As demand continues to increase without a comparable pace of new dispatchable generation, power markets are expected to become more volatile.
February 2026 ranked as the 17th warmest nationally since 1950 based on gas-weighted HDDs, with much of the country experiencing above-normal temperatures, including areas of the central U.S. that were up to 10 degrees warmer than average. Overall, winter 2025-2026 finished as the 25th warmest nationally. March 2026 has also begun significantly warmer than average across much of the country, and although some colder periods may occur later in the month in the East, the strong warm start makes it likely that March will end above normal overall.
