Which of the following is a primary focus of internal controls in banking?

The primary focus of internal controls in banking is ensuring compliance with applicable regulations. Internal controls are designed to prevent errors, fraud, and ensure that the bank operates within the legal framework established by regulatory bodies. Compliance with regulations not only protects the financial institution from legal repercussions but also helps maintain the integrity of the banking system as a whole. These controls include policies and procedures that manage risks, maintain accurate financial reporting, and safeguard the bank's assets.

Promoting aggressive sales tactics, maximizing revenue through marketing, and encouraging cross-department collaboration, while important in certain contexts, do not primarily align with the foundational purpose of internal controls. Those aspects can sometimes lead to risks if they overshadow the bank's need to comply with regulations and maintain a structured approach to governance and risk management.
