Oil traders spent Friday betting on diplomacy, sending Brent crude down 2% to about $104. By Sunday, Trump had rejected Iran's plan to reopen the Strait of Hormuz, and Iran's army said it was ready for renewed U.S. attacks. The real test comes when crude trading reopens: will the risk premium come roaring back?

Oil fell Friday on hopes that U.S.-Iran diplomacy could reopen the Strait of Hormuz. Then, after the close, the Wall Street Journal reported President Trump rejected Iran's 7-day proposal — while Tehran still waits for an official answer. Friday's selloff wasn't about barrels; it was about the possibility of a deal. The first trade back will show how much of that possibility survives.
