Up to 5 items of any size (as long as they can be carried in [[inventory]]) can be stored in a bank. Containers must be empty when deposited. There is no [[decay]] on stored items.
A character must designate a [[settlement token]] to use for bank actions. Items can only be deposited and withdrawn at the designated token. (It is not necessary to be a citizen of the settlement.) The bank can be moved to a different token at any time. The transition takes 24 real life hours, and the items inside are inaccessible during the process. If you disband your bank account is at a deedwhich is [[Deed#Disbanding|disbanded]], your bank account can be transferred to a new deed instantly.
The item storage is not shared between servers. This means you can't access items you stored on a different server, but neither do they count towards the 5 item limit.
