It's actually the opposite of fraud, because laundering money involves transactions which frequently make a great deal of money for the bank. Look at the fat fees Goldman Sachs earned setting up the 1MDB transactions for Malaysia. There was a lot of speculation around the financial crisis that banks opened their doors to money launderers because it was the only available liquid asset available in sufficient quantity to keep them solvent. So the bank actually has an incentive to launder money, so long as it can do so without being caught and fined or having its employees go to jail.

The point below is true though. Many of the same markers of fraud indicate money laundering, and having a good risk program can reduce both if that's your intention.
