On Friday morning, April 17th, Iran’s foreign minister announced the Strait of Hormuz is open to commercial traffic. Oil prices dropped 10% in response, the S&P 500 hit record highs, and President Trump declared the strait open for business. But the host of The Rundown is not ready to declare the crisis over. Ship owners are refusing to send their vessels through, Iran has warned it can shut the waterway again if the ceasefire doesn’t hold, and the economic damage from the last seven weeks is already baked into the global system.

This episode breaks down how much damage has already been done, why Iran’s economy held up better than expected, and how long it will take for things to return to normal.
