The CRO of a bank is conducting an internal assessment of the potential risk and vulnerability of the bank. The CRO starts by evaluating how risk management responsibilities are assigned to and connected across various business functions. Which of following statements regarding the interdependence of risk management functions is correct?

选项：

A.The operations function typically controls model implementation risks.

B.The senior management is in charge of monitoring market risk limits.

C.The risk management function is responsible for independently executing, recording, and settling trades.

D.The finance group is expected to provide support for the financial monitoring and modeling needs of the bank’s various business lines.

解释：

D is correct. The finance group is responsible for developing valuation and finance policies, ensuring the accuracy and completeness of reported earnings, and reviewing independent valuation methodologies and processes. Finance also manages business planning and is called upon to support the financial needs of the various business lines.

A is incorrect. The risk management function typically controls model implementation risks. A bank’s operations function not only shares in the implementation of risk management but plays a critical role in risk oversight as well. In investment banks, for example, its role is to independently execute, record, and settle trades; reconcile front and back-office positions; and chronicle all transactions. The operations staff also prepares earnings reports as well as independent valuations of the bank’s positions (e.g., mark-to-market).

B is incorrect. The risk management function is responsible for monitoring market risk limits. The senior management is in charge of setting business level risk tolerances, designing and managing policy, and evaluating performance.

C is incorrect. The operations function is responsible for independently executing, recording, and settling trades. The business line is responsible for taking on and managing exposure to approved risks as well as verifying valuations.
