The front office is literally the bank's interface with the market. The front office coordinates and handles all the needs of the bank and its clients with respect to hedging and financing.
Front-Office information systems :
The middle office, located very close to the front office, ensures the control and processing of transactions.
The back office monitors the post-market processing of transactions: confirmation, payment, settlement and accounting.
On all levels, the efficiency of the information system is defined by its ability to process transactions automatically and in a secure manner: the byword is STP (Straight Through Processing): the transaction is processed straight through. In other words, the transaction is processed with little or no manual intervention.
