Banks
Banks are locations found at various islands. To see which islands have a Bank, check the POI section for each island in the Island Guide.
Banks have a Banker NPC that you can speak to which offers a few functions listed below.
Currency Exchange
To exchange currency, simply place your bills in any of the slots and a total will be calculated. Then simply select the amount of each bill you would like to exchange for in the slots below until the total selected matches the total inserted. Once they match, the exchange button will become clickable and once clicked, the currency will appear in your inventory.
Storage
All players get 54 slots of bank storage at the start. They then have the ability to unlock more storage pages of 54 slots each for a price.
Bank Account
Each player has their own personal bank account that they can deposit or withdraw from. All bank accounts start at zero balance. Every deposit a player makes, the bank will take a 5% cut however withdrawals are free. The main purpose of the bank account is for freeing inventory and storage space, buying and selling goods on the market, and linking your personal and crew bank accounts.
