TLDR
- Military strikes by the US and Israel on Iran resulted in Ayatollah Khamenei’s death, propelling oil prices approximately 8% higher to nearly $80/barrel
- President Trump estimates the military operation will span 4–5 weeks; analysts emphasize conflict duration as critical for economic impact
- The eurozone faces greater vulnerability among major economies given its heavy dependence on Middle Eastern energy supplies
- A blockade of the Strait of Hormuz could drive crude above $100/barrel, potentially raising US gasoline prices to roughly $4.50/gallon
- Expectations grow that the Federal Reserve will maintain current interest rates as inflation threats intensify
Over the weekend, coordinated military operations by the United States and Israel targeted Iran, resulting in the death of Supreme Leader Ayatollah Ali Khamenei. The assault prompted retaliatory actions throughout the Middle East and caused energy prices to spike dramatically.
On Monday, crude oil prices climbed approximately 8%, surpassing the $80 per barrel threshold. Prior to this escalation, oil had been trading around $65 a barrel.

President Trump indicated the bombing operation should continue for four to five weeks, though he emphasized the United States stands ready to extend operations for “whatever it takes.” Defense Secretary Pete Hegseth assured this would not evolve into an extended engagement similar to Iraq.
Economic analysts stress that the conflict’s duration represents the most significant variable determining its impact on worldwide economic conditions. A brief military engagement may produce only temporary energy cost increases. An extended confrontation could trigger substantial economic disruption.
The Strait of Hormuz, where Iran maintains strategic control, serves as a vital passage for international energy transport. Approximately 20% of global seaborne petroleum and natural gas flows through this waterway. Tanker movements have already decreased since hostilities commenced.
What Happens If the Strait Closes
Should oil shipments through the strait remain disrupted, crude prices could stabilize above $100 per barrel, according to projections from Wood Mackenzie, an energy consulting firm. Such an increase would elevate US gasoline costs from the current $3 per gallon to approximately $4.50.
This surge alone would contribute 1.5 percentage points to US overall inflation, per analysis from ING’s James Knightley. Additional ripple effects would emerge through increased aviation fuel costs and transportation expenses.
The Federal Reserve had already suspended its interest rate reduction cycle. Former Treasury Secretary Janet Yellen stated the Iran situation “puts the Fed even more on hold.”
Economists at Natixis presented two potential scenarios. The first projects US economic growth slowing to 0.5%–1.5% this year. The second envisions economic contraction lasting at least two quarters should the conflict expand and disrupt international shipping networks.
The United States enjoys some insulation as it has achieved net energy exporter status. RSM chief economist Joseph Brusuelas noted the initial market reaction doesn’t present “any material risk to US growth or inflation outlooks” currently.
Europe More Exposed Than the US
The European continent confronts greater vulnerability. ING economist Carsten Brzeski characterized the eurozone as the “most exposed major economy” to consequences from the Iran crisis because of its reliance on regional petroleum and natural gas.
Conditions had been strengthening across Europe, with expanded government expenditure in Germany projected to underpin moderate expansion. The Iran escalation introduces fresh uncertainty into that economic revival.
Bloomberg Economics indicated that should the conflict prove brief, negative effects will remain limited. A protracted war maintaining elevated energy costs could compel European governments to increase spending to shield consumers.
European natural gas prices jumped significantly on Monday as Persian Gulf supplies faced jeopardy.
