Final answer:
No, a DISBO is not permitted to commingle funds in a safekeeping deposit because it can lead to conflicts of interest and mismanagement of funds.
Step-by-step explanation:
The question is asking whether a Depository Institution Supervisory Board Officer (DISBO) is allowed to mix client funds with their personal funds or with other clients' funds in a safekeeping deposit. In financial and legal practices, the action of mixing funds is referred to as commingling, which is typically restricted by regulations and standards of practice.
Commingling funds can lead to a conflict of interest, accounting complications, and mismanagement risks. Therefore, as a rule of thumb, a DISBO is not permitted to commingle funds. They are generally required to keep client funds in separate accounts to ensure there is no conflict of interest, to maintain transparency, and to promote responsible management of the funds entrusted to them.
