The US Treasury Department imposed sanctions on Wednesday on Karnakis & Karnakis, a law firm based in Greece and Panama, saying it had for years provided legal assistance to Iranian shipping networks.

The US Financial Crimes Enforcement Network also issued an administrative subpoena to advance an investigation into a Greek bank over potential ties to Iran, according to a Treasury statement, which did not name the bank.

FINCEN also issued requests for information to six other European banks that it did not name over relationships with Iranian financial institutions under US sanctions.

“Whether you are conducting illegal oil transfers at sea or sitting in the corner office of a law firm, if you are supporting the Iranian regime, we will find you and sanction you,” Treasury Secretary Scott Bessentsaid in a release.

Karnakis & Karnakis did not immediately respond to a request for comment.

Treasury also imposed sanctions on Singapore- and UAE-based shipping agents that it said directly aid Iranian shadow fleet operations.

Cerca de 521 milhões de toneladas de mercadorias foram transportadas através do Canal do Panamá no último ano fiscal (de 1 de outubro de 2025 a 30 de setembro de 2026), a bordo de quase 14 mil navios.
