How will the attacks affect oil and markets?

Immediate market and supply impacts

Global energy and financial markets reacted quickly to the strikes. Crude prices jumped as traders reassessed supply risks from one of the world’s major oil producers and the threat to key shipping lanes. Barclays warned Brent could move toward higher levels if tensions persist, and major exchanges showed increased volatility in energy, defense and currency markets.

Transportation and supply chains

Airlines and airports across the Middle East suspended or rerouted flights, with key hubs temporarily closing airspace; more than a thousand flights were reported canceled or diverted in the immediate aftermath. Shipping through the Strait of Hormuz—a strategic chokepoint for a large share of global seaborne oil—was disrupted after Iran’s Revolutionary Guard said passage was restricted, which heightened concerns about longer‑term supply interruptions.

Who feels it first

• Consumers: higher gasoline and diesel prices at the pump are likely as crude costs rise and insurers price in greater risk.
• Producers and shippers: companies with exposures to Middle East logistics face rerouting costs and insurance spikes.
• Financial markets: equities linked to travel, airlines and consumer spending can weaken while defense and energy firms often gain; broad market volatility tends to rise amid geopolitical shocks.

What could happen next

If strikes and reprisals continue, sustained pressure on shipping and production could push prices materially higher and keep volatility elevated. Central banks and policymakers monitor the economic effect closely because prolonged energy price shocks can slow growth and lift inflation, altering monetary and fiscal policy calculations globally.
