This lesson provides a detailed breakdown of the three lines of defence in treasury operations.

4.1 The Front Office (The Dealers)
The front office is responsible for the execution of treasury transactions and direct market interaction . Their key functions include:

  • Working with the business to identify financial exposures .

  • Providing market information and pricing advice .

  • Managing cash and executing deals in money markets, FX, interest rates, and long-term funding .

  • Entering deals into the Treasury Management System (TMS) .
    The front office should not be responsible for settlement or confirmation; these are back-office functions .

4.2 The Middle Office (The Risk Controllers)
The middle office acts as an independent control and risk management function, sitting between the front and back offices . Its primary responsibility is to ensure a sufficiently robust risk control framework is in place . Key functions include :

  • Ensuring deals are transacted in accordance with authorisation rules.

  • Monitoring limits (e.g., counterparty, position, stop-loss) and reporting breaches.

  • Analysing and reporting on exposures and performance.

  • Maintaining bank account and dealing mandates.

  • Processing and reconciling changes in standing data, such as Standard Settlement Instructions (SSIs).

4.3 The Back Office (The Administrators)
The back office provides the administrative and settlement support for treasury transactions . It does not execute deals. Its main functions are :

  • Confirming treasury transactions with counterparties in a timely manner.

  • Settling deals when they fall due.

  • Performing bank reconciliations to ensure all funds have moved as expected.

  • Accounting for all treasury transactions.

  • Providing all necessary reporting where no middle office exists.

  • Supervising the functionality and controls established within the TMS.

4.4 The Importance of Independence
For effective internal control, the front-office and back-office roles must be performed by different people with different reporting lines . This separation is critical to prevent fraud and detect errors . In some cases, the separation of reporting lines for Front Office, Middle Office, and Back Office should be distinct, with each reporting to different senior leaders to ensure true independence .
