US and Iran sign preliminary deal to end war and reopen Strait of Hormuz

Washington and Tehran have signed a preliminary agreement to end the war and reopen the Strait of Hormuz, even as negotiators leave critical questions open.

What's happening

The Strait carries a large share of seaborne crude, and its closure had rattled energy markets.

A framework is not a settlement — the hard bargaining starts now.

Pressure is mounting to convert the preliminary terms into a durable ceasefire.

Why it matters

Markets and capitals will watch whether the truce holds long enough to lock in specifics.
