The bank allegedly ignored specific US measures designed to prevent transactions being made involving terrorists, drug lords and rogue regimes. Two HSBC subsidiaries, for example, processed 25,000 transactions over seven years, worth a total of $19.4bn, without disclosing that the cash had links to Iran. The bank is also alleged to have moved billions of dollars in cash from Mexican subsidiary HBMX to its US network – despite being warned by both US and Mexican authorities that such sums could only be linked to drug trafficking.
