Why would a fort at Hormuz help the Portaguese to stop trade between the Arabian Peninsula and India?

A fort at Hormuz would allow the Portuguese to control the strategically vital Strait of Hormuz, a critical chokepoint for maritime trade between the Arabian Peninsula and India. By establishing a military presence there, they could intercept and tax ships passing through, significantly disrupting the flow of goods and enhancing their own trade dominance. This control would not only limit the economic power of rival traders but also enable the Portuguese to establish a monopoly over the lucrative spice and silk trades, further solidifying their influence in the region.
