The Real Costs of the Iran Conflict

The Strait of Hormuz is a 21-mile-wide waterway between Iran and Oman at the mouth of the Persian Gulf. Approximately 20% of the world's traded petroleum liquids and roughly 30% of global liquefied natural gas (LNG) transits through the strait. There is no alternative route for ships exiting the Persian Gulf — the Strait of Hormuz is the only exit. When the strait is closed, threatened, or operating under military tension, global energy markets price in that risk immediately.

Direct military costs of strikes against Iran include: advanced precision-guided munitions (the GBU-57 Massive Ordnance Penetrator bunker-buster bombs, used against hardened nuclear facilities, cost approximately $3.5 million each; the B-2 Spirit stealth bombers that deliver them cost approximately $135,000 per flight hour to operate), carrier strike group operational costs (a deployed carrier strike group costs approximately $6.5 million per day to operate), aerial refueling operations, Tomahawk cruise missiles (approximately $2 million each), and combat personnel costs and benefits. These direct expenditures are classified in total but individual component costs are public record.

The economic cost that falls on ordinary Americans is the energy price impact. When global oil supply is threatened or actually disrupted — whether through physical closure of the Strait, Iranian mining operations, or market uncertainty — oil prices increase. Every $10 per barrel increase in oil prices translates to approximately $0.24 per gallon increase in gasoline prices at the pump. This is a direct tax on every American who drives, heats with fuel oil or propane, or purchases any good that moves by truck. The effect is regressive: lower-income households spend a higher share of their income on fuel.

LNG exports through the strait supply energy to Europe, Japan, South Korea, and other U.S. allies. Disruption to those supplies raises energy prices in those markets, creates political pressure on those governments, and in some cases causes those allies to redirect LNG purchases that would otherwise flow from U.S. producers — affecting U.S. energy export revenue.

Military action against a nuclear program does not guarantee its permanent destruction — underground hardened facilities may survive strikes, and the political effect of military action is to strengthen the internal position of hardliners who oppose nuclear negotiations. The historical record shows that military strikes on nuclear programs (the Israeli strike on Iraq's Osirak reactor in 1981, the strike on Syria's Al-Kibar facility in 2007) delay but do not permanently eliminate nuclear capability when the underlying political decision to pursue it remains. The full cost-benefit calculation requires honest accounting of these downstream consequences.
