The Iran War Could Stretch Into 2027, and Your Gas Bill Could Stretch to the Max
Energy markets have been on alert in 2025 as fighting tied to Iran raises new concerns about oil supply, shipping routes, and fuel costs. For U.S. households, the immediate question is whether a longer conflict could mean pricier gasoline and higher home energy bills through 2027. Analysts and government forecasters have said the answer depends largely on crude exports, refinery margins, and whether traffic through the Strait of Hormuz is disrupted.
Oil markets are reacting to war risk, not just current supply
Brent crude rose above $80 per barrel in June 2025 as traders priced in a larger geopolitical risk premium, according to market data tracked by major exchanges and reporting from Reuters and Bloomberg on June 21 and June 22. About 20% of the world’s oil consumption moves through the Strait of Hormuz, according to the U.S. Energy Information Administration, making that waterway a central focus for fuel-price forecasts.
JPMorgan said in prior market notes that a severe Strait of Hormuz disruption could send oil sharply higher, with extreme scenarios moving well above $100 per barrel. The bank also said those outcomes depend on actual supply losses, not headlines alone. That distinction matters because Iran remained a significant oil producer in 2024 and 2025, while OPEC spare capacity was still concentrated in a few countries, according to the International Energy Agency.
What this could mean in the U.S., including local gas and utility bills
AAA’s national average gasoline price has historically moved with crude oil, often with a lag of days or weeks, and that pattern is again being watched in June 2025. The exact effect on any one state is not yet known, and utilities have not released any nationwide estimate tying customer bills directly to the current Iran conflict. States that rely more heavily on imported fuel, constrained pipelines, or summer power demand can see bigger price swings, but those impacts vary by market.
Natural gas and electricity bills do not always move in lockstep with oil, yet war-driven shipping disruption can still raise broader energy costs. The U.S. Energy Information Administration has said global fuel volatility can affect refining, diesel, and delivered energy prices even when domestic natural gas production stays high. In practical terms, drivers could see pump prices rise first, while household utility impacts would depend on local fuel mixes, rate cases, and wholesale market conditions through 2026 and 2027.
Why forecasters are looking as far out as 2027
Longer timelines are showing up because military conflicts, sanctions, shipping insurance costs, and refinery investment decisions can affect energy markets well beyond the first shock. The World Bank and International Monetary Fund have both warned in recent outlooks that geopolitical conflict can keep inflation pressure alive through commodity channels, especially when transport chokepoints are involved. That does not confirm that high prices will last until 2027, but it explains why banks, traders, and government agencies are modeling multi-year scenarios.
For consumers, the most grounded takeaway is that volatility is already real, while the worst-case price path remains conditional. The Federal Reserve has repeatedly said energy price spikes can feed into headline inflation, and the EIA has said retail fuel prices depend on crude costs, refinery operations, and seasonal demand. If the conflict stays contained, prices could ease; if exports or shipping are hit, Americans could keep seeing pressure on gas and home energy costs into 2027, according to current market outlooks.
