Which fiduciary responsibility requires the agent to keep the principal's financial information confidential?

The fiduciary responsibility that requires the agent to keep the principal's financial information confidential is loyalty. In a fiduciary relationship, loyalty encompasses the obligation of the agent to act in the best interests of the principal, which includes protecting sensitive information such as financial details. Maintaining confidentiality is essential because it builds trust, safeguards the principal's interests, and ensures that the agent does not use or share this information for personal gain or to the detriment of the principal.

Confidentiality stems from the broader principle of loyalty, where the agent must prioritize the needs and interests of the principal above all else. This aspect of fiduciary duty is crucial in establishing a strong, trust-based relationship between the principal and the agent, allowing the agent to effectively represent and advocate for the principal's needs without exposing them to unnecessary risk.
