Shareholders have accused the Commonwealth Bank and a host of senior executives, including chief Ian Narev and former chairman David Turner, of misleading the market in regards to investigations relating to the bank's alleged breaches of money laundering and terrorism financing laws.

CBA shareholders on Monday filed a class action claim against the bank in the Federal Court over the share price rout that occurred following revelations the bank was subject to civil action by the Australian Transaction Reports and Analysis Centre (Austrac).

Austrac launched legal action against CBA on August 3, accusing the bank of more than 50,000 breaches of money laundering and terrorism financing laws. The vast majority of the allegations relate to the bank not telling authorities about cash deposits of more than $10,000 at its ATMs.

CBA did not disclose the action to the market until August 4.
