How the Iran Conflict Could Trigger U.S. Inflation

Background Information:

​Geopolitical disputes in the Middle East have long played a critical role in shaping global economic conditions, particularly through their impact on the highly dependable oil markets. Iran, as a major oil producer and a key player in the Strait of Hormuz, through which roughly 20% of the world’s oil supply passes, wields significant influence over global oil prices. Historically, disruptions in this region have led to spikes in energy costs, notably gas prices, which often flow through the global economy and contribute toward inflationary pressures in countries like the United States. 

Following the outbreak of military conflict involving Iran, the Strait of Hormuz was temporarily closed, effectively removing close to 20% of global oil supply from the market. This marked the closure of one of the largest oil supply disruptions in modern history, exceeding past shocks such as the 1973 oil crisis. This disturbance pushed oil prices higher and demonstrated that even short-term closures can reduce global economic growth and create widespread inflationary pressures. Additionally, consistent attacks on oil infrastructure across the region have further intensified concerns about sustained supply shortages for the United States.​

Policy Overview:

Recent escalations in Iran – escalating from the US/Israel assassination of Iran’s Supreme Leader Ayatollah Ali Khamenei – have raised concerns about possible interruptions to oil supply chains. If tensions intensify, Iran could restrict access to the Strait of Hormuz, tightening the global supply. Additionally, the U.S. government may impose stricter sanctions, further limiting Iran’s ability to access global markets. These developments could drive oil prices even higher under the Trump administration, as markets react to both real and anticipated supply shortages.

Concurrently, the Federal Reserve is carefully monitoring inflation trends. If energy prices rise sharply due to geopolitical instability, it could complicate the Fed’s efforts to regulate inflation within the US.

Future Implications:

A continued disruption in the Strait of Hormuz would likely keep upward pressure on oil prices, with even short-term supply losses already pushing prices higher in early 2026. In the U.S., this has begun to translate into rising gasoline and transportation costs, adding to recent stickiness in inflation data. While the increases so far have been moderate, they signal how quickly energy shocks can feed into broader price levels.

Recent data suggests the inflationary effects are already emerging in the U.S. Since late February 2026, oil prices have surged from around $70 to over $110 per barrel, while the average U.S. gas price has jumped from $2.93 to nearly $4 per gallon, which is a roughly 36% increase and the largest one-month rise in decades. This sharp increase is already raising transportation and energy costs for consumers and businesses.

If the conflict continues, these pressures are likely to intensify. Higher fuel costs will increase shipping expenses across trucking, air travel, and manufacturing, causing higher prices for everyday goods such as food and retail products. Airlines have already begun raising fares, and sectors dependent on petrochemicals may also pass rising costs onto consumers, further pushing inflation upward. This would reinforce cost-push inflation and make it more difficult for inflation to return to the Federal Reserve’s 2% target.
