Iran Conflict Reshapes Energy Markets as US Gas Demand Surges

The United States is entering a phase of sustained, high industrial demand for natural gas, with consumption expected to hold at record levels through at least 2027. This trend, detailed in the U.S. Energy Information Administration's (EIA) latest Short-Term Energy Outlook, is underpinned by structural shifts in manufacturing and global trade, rather than mere cyclical fluctuations.

Industrial natural gas consumption in the U.S. hit a new record in 2025, surpassing the previous high set in 2023. The EIA forecasts continued growth, driven by energy-intensive sectors like petrochemicals, fertilizers, and metals processing. These industries leverage the United States' relative energy cost advantage compared to Europe and Asia, where fuel prices are considerably higher. Despite ongoing efficiency improvements in industrial operations, which moderate overall demand growth, the trend points towards a significant and lasting increase in gas consumption.

This domestic energy picture unfolds against a backdrop of escalating geopolitical tensions in the Middle East. The ongoing conflict involving Iran has become a major threat to global energy security, leading the EIA to sharply revise its assumptions for oil supply disruptions. The agency now anticipates that interruptions to Middle Eastern exports will be more severe and prolonged than previously expected.

"Dawn" highlights the critical role of the Strait of Hormuz, a vital chokepoint for global oil transit. The EIA now assumes the strait will remain effectively closed through the end of May, a significant extension of earlier expectations. This has led to substantial oil production shut-ins across the Middle East, with regional storage facilities approaching capacity limits. The continued U.S. blockade is also imposing additional export constraints on Iran, disrupting shipping routes. The confluence of rising U.S. industrial demand and Middle Eastern supply disruptions creates a complex and volatile global energy market.

Continued efficiency improvements reduce the amount of natural gas needed per unit of output.
