Stocks fell and oil rose on Thursday as investors assess negotiations to reopen the Strait of Hormuz. Brent crude, the international benchmark, rose more than 4% and hovered just below $83 a barrel at 4:05 p.m. The deal to reopen the Strait of Hormuz would exclude American and Israeli ships from transiting, according to Iran's state outlet Fars. They are a framework to resume negotiations between Tehran and Washington, which would begin a new 60-day period. The plan has not been publicly confirmed by Iran, and the White House has not commented on it either.
