Banks is a topographical surname that refers not to those places where people keep their money but to riverbanks or hillsides, and specifically the people who live on them. Just as Fields is a last name that relates to people who lived in, yes, fields, so Banks was a name originally given to people who dwelled on the banks of a river. Today, used as a first name, Banks is more likely to sound like an upwardly-mobile name related to financial establishments, okay if you're going for the glitter.

Banks as a girls' name was brought into the lexicon by actress Hilary Duff and musician Matthew Koma, who chose it for their daughter, Banks Violet. As both a surname and a word name, Banks refers to financial establishments as well as river banks.
