The bank in Star Trek Online is a universal storage facility for any inventory items. Items placed into any bank will appear in all banks throughout the galaxy and would be available for retrieval no matter which bank was visited.

Example: A medical assignment that requires 5 Medical Supplies is considered still a plannable assignment even though you have no Medical Supplies in your inventory, but have the minimum amount in your bank. If your ship sustains an injury, Minor components can be used to repair the ship even though you have no Minor Components in your inventory, but have the minimum amount in your Bank. If a rare sample trace is required for an assignment, the same assignment can be planned with the trace still in your bank and not in your inventory, and so on.
