What is the difference between correspondent intermediary settlement bank?

A correspondent bank is a financial institution that provides services on behalf of another bank, facilitating international transactions and access to foreign markets. An intermediary bank acts as a middleman in a transaction, usually when the sender and recipient banks do not have a direct relationship. A settlement bank, on the other hand, is specifically involved in the final settlement of transactions, ensuring that funds are transferred and accounts are reconciled. In summary, while all three types of banks facilitate transactions, their roles differ in terms of direct service, intermediary functions, and settlement processes.
