Iran will allow maximum 15 vessels daily through Strait of Hormuz under its US ceasefire agreement, according to Iranian sources. The waterway handles 20% of global oil. Ships must coordinate with Iranian military before transit. Currently, only six vessels passed in 24 hours versus 140 daily before conflict. Over 800 vessels await transit clarity. Iran reportedly charges tolls up to $2 million per vessel, disrupting global energy markets and shipping operations.
