Whistleblowers allegedly found billions of dollars' worth of previously undetected transactions between UK-based Standard Chartered (StanChart) and Iran-linked entities and terrorist organizations. The transactions happened between 2008 and 2013, after the bank said it would cease business with Iran in 2007. The whistleblowers made their claims in a U.S. federal court filing and highlighted transactions with a front company owned by Mohammad Bazzi, a Hizbollah financier, as well as with a Pakistani fertilizer company that allegedly sold explosive materials to the Taliban. StanChart has already paid more than two billion dollars in penalties for sanctions violations and due diligence failures.
