Event Summary

A Greek maritime risk management firm, Marisk, has warned shipping companies about fraudulent messages demanding cryptocurrency (Bitcoin or Tether (cryptocurrency)) for safe passage through the Strait of Hormuz. These messages falsely claim to represent Iranian authorities. The Strait of Hormuz, a crucial chokepoint for global oil and liquefied natural gas, has been subject to blockades by Iran, which has also proposed tolls for transit. The United States maintains a blockade of Iranian ports, further complicating the situation. Hundreds of ships and thousands of seafarers remain stranded in the Gulf, with some vessels reportedly fired upon when attempting to pass through the strait.
