I always interpreted them as just property and finance storage. Imagined them as efficient institutions that store your property via a network of, like, pocket dimensions that can be remotely accessed from any branch of the bank. Figured that, for either a nominal fee or permission to use your funds (i.e, for loans, exchanges, and investments), they could track and store whatever you wanted to give them.

Raw fish probably wouldn't work, though. For the obvious reasons.
