What are the possible consequences for a bank that invests discretionary personal-trust-account assets in its own certificates of deposit with below-market interest rates?

Investing discretionary personal-trust-account assets in a bank's own certificates of deposit at below-market interest rates can lead to significant legal and financial ramifications for the bank, primarily because this action could be seen as a violation of fiduciary duty. A court may indeed order the bank to reimburse the accounts for any foregone interest, as this reflects a failure to act in the best interest of the trust beneficiaries. Fiduciary duty requires that the bank seeks the best possible returns for the trust assets, and directing funds to below-market rate investments can be interpreted as a breach of this responsibility.

When banks manage trust funds, they are legally obligated to prioritize the beneficiaries' interests above their own.
