Front office

Front office is generally described as a revenue-generating role. There are two main areas within front office: investment banking and markets.

Markets is divided into "sales and trading" (including "structuring"), and "research".

Middle office

This area of the bank includes treasury management, internal controls (such as Risk), and internal corporate strategy. Corporate treasury is responsible for an investment bank's funding, capital structure management, and liquidity risk monitoring; it is (co)responsible for the bank's funds transfer pricing (FTP) framework.

Back office

The back office data-checks trades that have been conducted, ensuring that they are not wrong, and transacts the required transfers. Many banks have outsourced operations. It is, however, a critical part of the bank.
