The NDIC protects bank depositors against loss through:
a) Deposit Guarantee
This is the most significant and distinct role of the NDIC. As a deposit insurer, the NDIC guarantees payment of deposits up to the maximum insured sum of N500,000 to a depositor in Banks and PMBs and N200,000 to a depositor in MFBs in the event of failure of a participating financial institution. Balances in all deposit accounts held in the same right and capacity by a depositor in all branches of the closed insured institution, net of outstanding debts, are aggregated to determine the maximum insured amount.
b) Bank Supervision
The NDIC supervises banks to protect depositors, ensure monetary stability, and effective/efficient payment system as well as to promote competition and innovation in the banking system. Banking supervision seeks to reduce the potential risk of failure and ensures that unsafe and unsound banking practices do not go unchecked. It also provides the oversight functions required to preserve the integrity of and promote public confidence in the banking system.
c) Failure Resolution
The NDIC is empowered to provide financial and technical assistance to failing or distressed banks in the interest of depositors. The financial assistance can take the form of loans, guarantee for loan taken by the bank or acceptance of accommodation bills. On the other hand, the technical assistance may take the following forms: take-over of management and control of the bank; change in management; and/or assisted merger with another viable institution.
