Oil has fallen 20% from its 2026 peak as the U.S. and Iran move closer to a ceasefire deal that could reopen the Strait of Hormuz. Falling fuel costs are a direct tailwind for airlines.

## Idea

A ceasefire between the U.S. and Iran would reopen the Strait of Hormuz, the world's most critical oil shipping lane, and unleash a flood of supply that could keep fuel prices depressed for months. For airlines, jet fuel is their single biggest expense — sometimes a third of operating costs — so every dollar oil drops flows almost directly to the bottom line. Oil is already down 20% from its peak, but airlines haven't fully priced in a sustained drop because traders are still waiting for the official deal announcement. If the ceasefire materializes, airline stocks tend to rally sharply and quickly as earnings estimates get revised upward.
