U.S. Bank, the 5th largest commercial bank in the US, was charged by the federal authorities with failing to guard against illegal activity and, in at least one instance, even abetting it.
The action against U.S. Bank was modest compared with cases involving banking giants like HSBC and Standard Chartered that the authorities found had done business with drug gangs and countries like Cuba and Iran that had been barred from the United States financial system under international sanctions. In 2012, for instance, federal prosecutors settled a money-laundering case against HSBC for $1.9 billion.
