Iran’s newly established Persian Gulf Strait Authority (PGSA) said vessels violating traffic rules in the Strait of Hormuz will face fines, detention or confiscation, according to a statement posted on X. The warning follows the expiration of a 60-day ceasefire window without a new agreement between Tehran and Washington, amid a six-month-old conflict in the Middle East.
Cargo owners are now required to consult an updated list of vessels deemed non-compliant for voyages linked to the Persian Gulf. Ships involved in ship-to-ship transfers or transshipment with listed vessels will automatically be included. To be removed from the list, owners must submit a formal request with supporting documentation to Iranian maritime authorities.
The move coincides with the Trump administration’s announcement of additional sanctions targeting Iran’s financial partners. Treasury Secretary Scott Bessent described the measures as an economic "D-Day," stating they represent the largest financial offensive ever mobilized against Tehran. In an opinion piece published Sunday in the Financial Times, Bessent wrote that the sanctions would begin "at dawn" on Monday and serve as the final outcome of the U.S. campaign against Iran.
Washington has framed the new measures as part of a broader effort to isolate Iran’s economy, which it described as in "free fall" due to galloping inflation and the collapse of the local currency. The existing sanctions regime already covers Iran’s banking, energy, aviation and cryptocurrency sectors. Bessent warned that any nation serving as a financial conduit for Tehran must expect to share in its isolation.
A press conference scheduled for 2 PM Monday will detail the new sanctions, which take effect immediately. While the two countries have not exchanged military strikes in recent weeks, negotiations to end the conflict have stalled, leaving the economic pressure campaign as the primary tool of enforcement.
