Bank was under supervision by US Department of Justice-appointed team because of previous violations
HSBC discovered a suspected money laundering network that received $4.2bn (£3bn) worth of payments, it has emerged, raising questions over whether it disclosed the information to US monitors who at the time were ensuring the bank cleaned up its act.
Insiders who spoke to journalists as part of a joint investigation by the Guardian and the Bureau of Investigative Journalism, have suggested that HSBC may not have appropriately shared the information with the monitoring team installed by US regulators in 2012 after HSBC allowed drug cartels in Latin America to launder hundreds of millions of dollars through its accounts.
