The current conflict in Iran has developed and shifted from a narrow military conflict between the United States and Israel into a broader economic conflict, as Iran has effectively closed the Strait of Hormuz and dramatically disrupted world energy markets. According to Geopolitical Monitor, Iranian military forces have employed various tactics to block maritime shipping and impede safe shipping through the Strait of Hormuz, which is an important artery for crude oil supply for approximately 20% of the world’s daily oil trade and a significant portion of the liquefied natural gas trade. Iran’s actions have also included a demand for safe passage through the Strait of Hormuz, which purportedly requires payment of at least USD 2 million per ship, effectively creating a blockade of the Strait of Hormuz, which has already resulted in at least USD 2.5 trillion in worldwide economic damage according to Bloomberg data from recent information.
For consumers in the United States, the consequences of the conflict in Iran no longer feel theoretical but rather a reality. According to AAA, the average price for regular gasoline increased to USD 3.99 per gallon during the last week of March, which is greater than a USD 1 increase from the prices before the conflict. As reported by Reuters, there have also been sharp price increases in several refined petroleum products (e.g., gasoline, jet fuel, and diesel), with prices nearly doubling in key Asian markets just within the last few weeks. These price increases are being blown through the entire economy, creating ripple effects in things like airline tickets and grocery prices.
“The inflation tax is Washington’s own doing,” says one from the Geopolitical Monitor, warning that the impact of the war on the economy is now being felt at the fuel station rather than on the headline crude oil prices. The International Monetary Fund (IMF) considers the disruption to the Strait of Hormuz to be “a large and sudden income tax” on countries that import fuel, and has sounded the alarm for higher prices and lower growth worldwide. The Organisation for Economic Co-operation and Development (OECD) projects a current growth rate of only 2.9 percent in 2026. It predicts that inflation in the G-20 will be 1.2 percentage points greater than previously forecasted.
U.S. leaders believe that because of domestic shale oil production and Strategic Petroleum Reserves, they have a cushion that is not available to Europe or Asia. The overall geoeconomic picture is more troubling than simply fuel prices, however. Attacks on natural gas fields and supporting infrastructure in the region have severely disrupted aluminum refining, which the United States classifies as “strategically important” to national defense/aerospace; fertilizer exports from the Middle East, which normally account for around 1/3 of what’s imported by the rest of the world, are also seriously disrupted. Middle Eastern urea prices have increased by more than $90 per metric ton, heightening food security fears, exacerbated by American farmers who will have to pay significantly higher input costs this planting season.
The ongoing conflict in Iran has brought back memories of the importance of maritime chokepoints to U.S. military strategy as well as to the historical military theories of Alfred Thayer Mahan regarding sea lanes. The reopening of the Strait of Hormuz by military action is a dangerous way to achieve that and will likely be met with multiple American military losses if there is an extended war. Also, if the Strait of Hormuz is not opened to free navigation, it will diminish U.S. credibility as the guarantor of the world’s sea lanes — a key element of U.S. power projection since World War II.
The influence of the conflict is political as well. Geopolitical Monitor (2022) forecasts that the combination of rising energy prices and persistent inflation will lead to national voter dissatisfaction in the U.S., and in some cases, create radicalized political movements in other countries before midterm elections later this year. A recent assessment of the impact of the conflict on global elections to be held in 2026 shows that rising energy prices are, and will continue to be, a primary driver of discontent in many countries.
The suspension by the Trump administration of some Iranian oil sanctions indicates that the economic impact of the conflict is proving more difficult to contain than originally believed. The International Energy Agency (IEA) has already coordinated the release of 400 million barrels of oil from global strategic reserves. G7 leaders have committed to taking “all necessary actions” to stabilize energy markets globally as part of a coordinated response to the Iran conflict.
The question remains — what will the end of this conflict look like? Will the United States and its allies continue to support the liberation of the strait at the potential risk of large military losses? Or will they allow the strait to remain closed?
In the view of the Global Monitor, the Third Gulf War is not just a military race, but a trial of geoeconomic endurance. With the re-drawing of borders from the military strategy of the nation to include barrel oil (and other commodities), disruption in supply chains, and the subtle weaponization of interdependence globally.
The U.S. policymaker’s challenge is to maintain U.S. strategic advantages in the Middle East without jeopardizing California’s economic viability.
