Oil has fallen 20% from its 2026 peak as President Trump signals a ceasefire deal with Iran is close. Government bonds are having their best week since the war started because falling oil means lower inflation pressure.

## Idea

The Strait of Hormuz was shut down when the Iran war started in February, causing a massive energy shock that drove oil prices and inflation higher. Now Trump says a peace deal is imminent, which would reopen that critical shipping lane and remove the oil premium. Falling oil prices are great for bonds because they signal lower inflation ahead — and indeed Treasuries are already posting their best week since the war began. If a deal actually gets signed, oil could keep falling and bond prices could keep rising as markets price in a return to normal. The trade works best by buying medium-duration government bond ETFs, which benefit directly from lower inflation expectations.
