What do our foreign exchange rates represent? Republic Bank publishes different types of foreign exchange rates based on how the currency is being purchased or sold. Below is a simple guide to help you understand what each rate represents. Buy (Cash): The rate the Bank uses when purchasing physical foreign currency (cash) from customers at our branches. Buy (Demand): The rate applied when purchasing foreign currency through non-cash transactions, such as wire transfers, drafts, or account-related foreign exchange transactions. Sell (Demand): The rate applied when selling foreign currency through non-cash transactions. The RepublicMobile App displays Buy (Demand) and Sell (Demand) rates only while the Buy (Cash) rate is not currently available on the Mobile App. If you are planning on exchanging foreign currency cash, always check the Buy (Cash) rate online or at your nearest branch.
