The US Central Bank announced on Tuesday that it had ordered Credit Suisse Group to strengthen its anti-money laundering policy after finding procedural "shortcomings" in its operations in the United States.

The Federal Reserve (Fed) has given the bank 90 days to adopt a plan to reform and strengthen its anti-money laundering policy, according to an agreement it made public.

The Fed requires increased monitoring of potentially illicit activities and requires Credit Suisse to report regularly on its progress.

According to the terms of this agreement, Credit Suisse 's plan "must provide a sustainable governance framework that, at a minimum, addresses, takes into account and includes actions to improve policies, procedures and controls for BSA (Bank secrecy act, editor's note) / AML (anti-money laundering, editor's note) through American operations".

The Fed adds that this should not be limited to US activities.

Credit Suisse had not yet reacted at the end of the afternoon.

In December 2016, the Swiss establishment was fined $16.5 million in the United States for similar acts.

He was then accused of not having detected illegal transactions carried out by entities not registered with American regulators between January 2011 and September 2013.

The financial regulator (Finra) had explained that 55 million shares of medium-sized companies had changed hands during this period between foreign entities via Credit Suisse without this being reported to the authorities.

The bank had also not been vigilant about suspicious money transfers between January 2011 and December 2015. At the time, it appeared that an insufficient number of people had been assigned to risk control, so that the alerts issued by the automatic surveillance system had not been analysed.

In addition, many data entered into the automatic monitoring system were incomplete or flawed, which compromised (from the outset) the effectiveness of the entire system, had lamented Finra.

Credit Suisse had agreed to pay the financial penalty via one of its subsidiaries but it had not admitted its guilt, a strategy allowing it to keep its banking license.
