Oil prices just posted their worst monthly decline in six years because President Trump says a peace deal with Iran is imminent. If the Strait of Hormuz reopens and Iranian oil starts flowing again, energy prices could keep falling — and that's great news for fuel-hungry airlines.

## Idea

The Iran war has choked off the Strait of Hormuz — the world's most important oil shipping lane — since February, causing a massive energy price spike. Now Trump says a final decision on a deal is coming, and oil is cratering with its biggest monthly drop in six years. Airlines are one of the biggest losers when fuel costs spike, so they stand to benefit the most when those costs come back down. If a ceasefire deal is formally announced, expect airline stocks to gap higher as the market prices in a sustained period of cheaper jet fuel. Even the anticipation of a deal has already pushed oil down sharply — the actual deal could send it even lower.
