High oil and gasoline prices and energy supply problems won't be solved overnight, despite an agreement to end the Iran war and open the Strait of Hormuz announced Sunday.

The slow pace of the process of shipping and refining crude oil, and doubts about the security of traveling through the strait mean the effect won't be seen immediately, they said.
