This morning we are down to ~798, after the first two cargo vessels have crossed the Strait of Hormuz since the ceasefire, according to ship tracking data.

The Liberia-flagged Daytona Beach, destined for the United Arab Emirates, crossed just before 8am UK time, while the Greek-owned NJ Earth followed about two hours later, with its destination undisclosed, the tracking platform Kpler showed.

The ships are the first large vessels to transit the critical waterway since the agreement of a two-week ceasefire, under which Iran has claimed it would maintain control of the strait. It was unclear if they paid any tolls to make the crossing. Around 175 million barrels of crude and refined products are currently loaded on to 187 tankers in the Gulf, according to Kpler data — which could now start to move, depending on what happens in the strait.

Regarding Hormuz transit, Iran said it 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 passage through the key waterway during the two-week ceasefire, the FT reported.

Hamid Hosseini, a spokesperson for Iran's Oil, Gas and Petrochemical Products Exporters' Union, told the FT on Wednesday that Iran wanted to collect tolling fees from any tanker passing and to assess each ship.

"Iran needs to monitor what goes in and out of the strait to ensure these two weeks aren't used for transferring weapons," said Hosseini, whose industry association works closely with the state. "Everything can pass through, but the procedure will take time for each vessel, and Iran is not in a rush," he added. 

Decisions on the conditions for passing the strait are taken by Iran's Supreme National Security Council. 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.

Hosseini said that each tanker must email authorities about its cargo, after which Iran will inform them of the toll to be paid in digital currencies. 

He said that the tariff is $1 per barrel of oil, adding that empty tankers can pass freely.

"Once the email arrives and Iran completes its assessment, vessels are given a few seconds to pay in bitcoin, ensuring they can't be traced or confiscated due to sanctions," Hosseini added.

Speaking to CBS this morning, Trump said that there may be a joint US-Iran venture for Hormuz tolls.
