The Financial Post reports in its Thursday edition that Iran will demand that shipping companies pay tolls in cryptocurrency for oil tankers passing through the Strait of Hormuz, as it seeks to retain control over the key waterway during the two-week ceasefire. A Financial Times dispatch to the Post reports that Iran's Oil, Gas and Petrochemical Products Exporters' Union official Hamid Hosseini said Wednesday that Iran wants to collect toll fees from any passing tanker. He said: "Iran needs to monitor what goes in and out of the strait to ensure these two weeks aren't used for transferring weapons. Everything can pass through, but the procedure will take time for each vessel, and Iran is not in a rush." Decisions on the conditions for passing the strait are taken by Iran's Supreme National Security Council. Mr. Hosseini's remarks suggest Iran will require any tankers to use the northerly route close to its coastline, raising questions over whether western or Gulf-state-linked vessels will be willing to risk transit. Mr. Hosseini said each tanker must e-mail authorities about its cargo, after which Iran will inform them of the toll to be paid in digital currencies. Saudi Arabia is demanding full and free Hormuz passage.
