Similar to the previous post regarding online commerce, every time you log into your bank you're conducting a 1-factor authenticated transaction. Sure, Bank of America has "SiteKey" which asks you for additional knowledge-based credentials (Something You Know) but other than a clever image-oriented system to help you avoid entering those credentials into a fake version of their website, this system, and systems like it, don't help protect you. They help prevent your credentials from being stolen, sure, but as we saw in the Dateline piece, those credentials are fairly easy to obtain or guess - and once obtained, you're in big trouble.
What's needed is a true 2-factor authentication system to validate your identity before you log into the bank website.
The Financial Services Technology Consortium issued recommendations on this subject, available at the following URL:

We wholeheartedly agree with this document, especially their statement that “no authentication system should rely solely on passwords or other knowledge-based queries or shared secrets. If a password should be compromised, it must not be feasible for an impostor to defeat authentication with just knowledge of a password and an associated claim—e.g., userid, account number, name, SSN.”
