Bank

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.

Cargo Bay
For the purposes of item possession for Ship and officer injuries and duty officer assignments, the contents of the bank are available even if they are not in your character's inventory.

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.

Bank slots
For Gold players, your bank gains more slots as you progress through the game allowing you to store more items.

An additional 12 bank slots (character unlock) can be purchased from the Zen Store for 300, up to seventeen (17) times per character. Should a character at or near the limit receive a promotional bundle that would put them over the limit of Bank slots, an account-bound will be placed in their inventory instead.

Account-Shared Bank
An Account-Shared Bank is extra inventory that all characters on a given account have access to unlike normal bank storage. Note that any form of injury-repairing item, such as a regenerator or components, cannot be used from the account-wide bank. Gold Players were granted free access to 20 slots of Account-Shared Bank storage while silver players must buy initial access to 10 slots of storage. These have a capacity of 1 billion energy credits.

An additional 10 account-shared bank slots can be purchased from the Zen Store for 1000. Gold players can purchase additional access up to ten times to total 120 slots while silver players are granted up to 100 total slots.
