Trump said the U.S. would keep the Strait of Hormuz open and toll-free for international shipping. He also discussed imposing a blockade on Iranian ports as part of broader measures against Iran during ongoing military tensions. While the blockade announcement grabbed attention, the details of how it would work and what vessels it would affect remain unclear from available reporting. The discussion of stricter measures against Iran's maritime activity did trigger concerns about potential impacts on oil markets and global shipping, given the strait's critical role in world energy supplies. However, the specific economic effects depend on how these measures are actually implemented.
