Swiss financial watchdog Finma conducted "extensive investigations" into Credit Suisse's dealings surrounding Malaysia's scandal-hit state fund
1MDB, resulting in a written reprimand for Switzerland's second-biggest bank.
"During the investigations, it was not established that the bank had committed any systematic breaches of supervisory law," a Finma spokesman said in an emailed statement.
"Finma did, however, send the bank a written reprimand for its money-laundering processes."
It did not give any more details.
Earlier, Singapore's central bank said it had fined Credit Suisse and United Overseas Bank a total of S$1.6 million ($1.15 million) for breaching anti-money laundering rules in connection with transactions related to 1MDB.
