They'll help you launder $100 million, but not $10000.

Actually, no; they won't.

That is unless you find a crooked banker (probably a number of them), which is willing to help.

While it's a nice illusion that a bank will do anything for money and this may have been the case 30 years ago this has massively changed.

The reputational risk and the risk of criminal prosecution, including loss of the banking license in critical markets, is much too big as that a reputable bank would willingly engage in such shenanigans nowadays.

That's not saying that it doesn't happen (see recent examples), but if it happens it's virtually always under circumvention of risk management and compliance departments at a bank.

That's just mincing words. Fine, so it won't be a bank that helps you launder $100 million, but an employee of the bank. Ultimately, it is a human that makes the decision, not some abstract entity. I thought it would be obvious (and won't require the addressing of every irrelevant technicality) that banks don't provide money laundering services in their catalog, but above a certain sum, you can just shop around until you find willing individuals. Happy now?
