What Large U.S. Energy Buyers Need to Know About the Iran Conflict

Last August, we examined the fundamental factors driving domestic energy economics. The article identified natural gas storage, the supply/demand balance, and geopolitics as primary cost drivers. That analysis warned: “Should conditions deteriorate to where shipping through the Strait of Hormuz becomes untenable, energy markets everywhere will experience tremendous upheaval.”

While gas storage and supply remain favorable, the concerning geopolitical scenario is now unfolding. One day after Iranian forces launched an attack on two oil tankers in Iraqi waters, Iran’s new supreme leader, Ayatollah Mojtaba Khamenei declared that the Strait will remain closed as a “tool of pressure” and that the U.S. and its allies must pay “compensation” for the recent military escalation.

The Strait of Hormuz is a narrow passageway through which roughly 20% of the world’s oil and LNG transits to global markets. Iran’s geographic and military position can restrict these flows—with severe consequences for energy markets worldwide.

The International Energy Agency (IEA) has warned that the recent conflict has created the “largest supply disruption in the history of the global oil market.” In response, IEA member countries have agreed to distribute 400 million barrels of oil (172 million from the U.S.) – the largest Strategic Petroleum Reserve release in history.

Oil Prices Are Higher, But How Does That Impact Natural Gas and Electricity Prices?

Natural gas is the dominant fuel for electricity generation in the U.S., and its flexibility and abundance make it the marginal fuel as well. This means that as the power grid ramps up to match supply with demand, it is the price of natural gas that sets the price of the next additional megawatt of electricity needed by the grid. In most markets across the country, there is a >90% correlation between the price of the two commodities.

While the conflict in Iran has not had a major impact on domestic natural gas prices, there has been a sharp uptick in global gas prices as indicated in the chart of prompt-month European gas below:

European and Asian markets have seen sharp price increases as Middle Eastern LNG flows have been curtailed.

U.S. Henry Hub prices remain largely insulated, supported by record domestic production and healthy storage levels. However, the price premium in international markets creates strong incentive to maximize LNG exports. With export terminals currently operating near capacity, producers are accelerating expansion projects to move more American gas abroad. As export volumes increase, domestic supply will tighten—and Henry Hub prices will follow.

What This Means for Your Energy Strategy

Energy markets are efficient: they move quickly to eliminate arbitrage and price-in new information. Despite the geopolitical uncertainty, domestic market fundamentals remain generally favorable:

• Inventories at the end of withdrawal season are in line with the 5-year average at more than 1,800 Bcf.
• Domestic gas production continues to inch north of all-time highs at more than 110 Bcf per day.
• LNG export capacity is fully utilized, a condition likely to persist through the remainder of 2026.
• Forward pricing curve is backwardated (lower prices for longer terms).

Prices may hold near present levels in the near term, but history shows that energy markets can reprice rapidly. The Middle East situation remains unresolved, and the timeline for a return to normal supply flows is unknown. For buyers, the forward curve’s backwardation presents a concrete opportunity to lock in long-term price protection while conditions are still favorable.
