The bank hands out ATM cards, but does not offer the customer the option
of logging in with SafeWord or SecureId or any other OTP.  Given how
much the bank saves in labor, it could surely afford the card expense.
But it's easy to see why they don't, since it's the customer, not the
bank, that is taking the risk.

A sufficiently fancy trojan would notice when the user logged into the
bank using OTP and change the destination of a money transfer or add
an invisible transaction, but that's certainly quite a lot harder than
a simple keystroke logger.
