Sal Mercogliano, maritime historian at Campbell University and host of "What's Going on With Shipping," offers his experience to investors as the U.S.-Iran conflict continues and concerns around the Strait of Hormuz persist. He ties his historical insight to economic impacts of the blockades in the strait and how he sees the development shaping out. Sal later discusses how he sees it all impacting chances for the U.S. and Iran to reach a peace agreement.
