Almost every business has a bank account, and the relationship with the bank is a contract with its own rules. The bank must honour the customer’s cheques when it can, keep his affairs secret, and collect money for him. The customer must draw cheques carefully and tell the bank of any fraud.
Banks themselves are regulated, because their failure harms the public, so there are rules about who may carry on banking, what reserves they must hold and how they deal with their directors. At the top stands the Central Bank of Nigeria, which controls the currency.
Examiners ask for lists of duties, rights and bank types, and for short problems on a bank’s refusal to pay a cheque or its disclosure of an account.
This topic covers the meaning of bank and banker, the types of bank (commercial, merchant and specialised) and other financial institutions, banking business, the bank customer, the duties and rights of bank and customer, the statutory duties of licensed banks under the Banks and Other Financial Institutions Act 2020 (BOFIA), and the objects and powers of the Central Bank of Nigeria.
In 30 seconds
A bank in Nigeria is a bank licensed under BOFIA 2020 (section 131). Banking business is receiving deposits on current or savings account, paying or collecting cheques, providing finance and advisory services, and managing investments. Only a company incorporated in Nigeria with a Central Bank of Nigeria (CBN) licence may carry on banking business (section 2(1)), on pain of at least five years’ imprisonment or a fine of at least ₦50,000,000.
A customer is a person with an account in his name. The bank must honour the customer’s mandate if the account is in funds, the cheque is regularly drawn and there is no legal impediment, keep the account confidential (four exceptions), and not pay a countermanded cheque. The customer must draw cheques with care and notify the bank of suspicious dealings.
A bank must put 30% (or 15%) of net profits to a reserve fund before dividends. The CBN has five objects and the sole right to issue notes and coins.
Bank and banker
The words “bank” and “banker” are hard to define. The Bills of Exchange Act 1882 defines a bank as any body of persons, incorporated or not, who carry on the business of banking. Under section 131 of BOFIA 2020, it is settled that in Nigeria a bank is a bank licensed under the Act, and it includes:
| Type | Meaning |
|---|---|
| Commercial bank | Transacts banking business by accepting deposits and paying money by cheques and cash. It is engaged more in everyday retail banking than in wholesale banking |
| Merchant bank | A bank whose business includes receiving deposits on deposit account, providing finance, consultancy and advisory services on corporate and investment matters, and making or managing investments for any person |
| Specialised banks | The Bank of Industry, Bank of Agriculture, Development Bank of Nigeria, Nigerian Export Import Bank, The Infrastructure Bank, Federal Mortgage Bank of Nigeria, Nigeria Mortgage Refinancing Company, primary mortgage banks, microfinance banks, non-interest banks, and other banks the CBN designates |
November 2023 asked for five specialised banks (5 marks), and the list above gives ten to choose from.
Other financial institutions
BOFIA also authorises “other financial institutions”: any individual, body or group, corporate or not, other than the licensed banks, that carries on the business of a discount house, finance company, money brokerage, authorised buying of foreign exchange, international money transfer services, mortgage refinancing company, mortgage guarantee company, financial holding company or payment service provider, whether the business is conducted digitally, virtually or electronically only.
Companies whose objects include factoring, project financing, equipment leasing, debt administration, fund management, private ledger services, investment management, local purchase order financing and other designated business are also covered.
Who may carry on banking business
Section 2(1) BOFIA prohibits anyone who is not a company incorporated in Nigeria holding a valid banking licence from the CBN from carrying on banking business. A person who violates it is liable on conviction to imprisonment of not less than five years, a fine of not less than ₦50,000,000, two times the cumulative deposits or other amount collected, or both imprisonment and fine.
Banking business
Section 131 defines banking business as the business of:
- receiving deposits on current account, savings account or similar account;
- paying or collecting cheques drawn by or paid in by customers;
- providing finance, consultancy and advisory services on corporate and investment matters;
- making or managing investments for any person, even if conducted digitally, virtually or electronically only; or
- other business the Governor of the CBN designates by order in the Gazette.
November 2016 asked for five businesses of a commercial bank (5 marks).
The bank customer
A bank customer is any person who has an account in his name with a bank. He becomes a customer when the bank opens the account. As in all contracts, there is an offer by the prospective customer to have an account opened and acceptance by the bank. Only the person whose name appears in the bank’s books as holding an account is a customer.
Duties of the bank to the customer
May 2021 and November 2021 tested the key ones. The bank must:
- collect the customer’s cheques, cash and other payable instruments;
- abide strictly by the customer’s mandate, and honour his cheques and written demands to pay, provided that: (i) the account is in funds, (ii) or a credit arrangement has been agreed, (iii) the cheque is regularly drawn, and (iv) there is no legal impediment to payment;
- keep the account confidential and secret, subject only to the legal exceptions below;
- give reasonable notice before closing the account;
- bring to the customer’s immediate notice any suspicious dealings that may lead to fraud or unauthorised dealings;
- provide regular updates and statements of account;
- keep the customer’s accounts separate, unless he has agreed otherwise (British and French Bank v Opaleye);
- not pay out on a validly countermanded cheque. A bank that pays a stopped cheque is liable to the customer;
- not charge unreasonable interest on loans and overdrafts (Barclays Bank DCO v Hassan); and
- take reasonable care in opening accounts for new customers by obtaining adequate information about their standing. If it fails, it may lose the protection of section 82 of the Bills of Exchange Act for crossed cheques (United Nigeria Insurance v Muslim Bank). Where the new customer is a limited company, the bank must take references on the directors and demand the memorandum and articles (Bewac v African Continental Bank).
Beyond care, the bank must show skill in dealing with the customer’s banking affairs, across all his transactions (Agbanelo v Union Bank).
The duty of confidentiality and its four exceptions
The bank may divulge information on the account only:
- where disclosure is compelled by law;
- where there is a public duty to disclose;
- where disclosure is in the bank’s interest; or
- with the customer’s consent.
May 2021 and November 2021 asked for three instances each. The Money Laundering Act is an example of the first: a bank must report suspicious transactions despite the duty of secrecy. In November 2021 the examiners also asked when a bank may avoid the duty to keep accounts separate. The syllabus’s answer is where there is an agreement with the customer to the contrary.
Duties of the customer to the bank
May 2022 asked for four (8 marks). The customer must:
- draw his cheque with care and diligence, to protect his account from fraud and discourage unauthorised transactions;
- give instructions in writing to the bank when withdrawing his money;
- notify the bank promptly of any suspicious dealings that come to his knowledge, such as a missing cheque book or leaf, or forgery of his signature; and
- pay appropriate bank charges, such as commission and interest on loans.
Rights of the bank
November 2017 asked for five rights (5 marks). The bank has the right to:
- charge reasonable interest on credits and commission on turnover;
- use the money deposited with it, without approval from the customer;
- close the account on reasonable notice;
- a lien over the customer’s property in its possession, in appropriate circumstances;
- refuse payment on an improperly drawn cheque or other instrument;
- recall an overdraft on current account, in appropriate circumstances;
- set off, as the law allows; and
- reimbursement of expenses reasonably incurred on the customer’s behalf.
Statutory duties of a licensed bank (BOFIA sections 15 to 22)
| Duty | Content | Penalty |
|---|---|---|
| (a) Reserve fund | Out of annual net profits after tax and before any dividend, transfer to the reserve fund not less than 30% if the fund is less than paid-up capital, or not less than 15% if it equals or exceeds paid-up capital | A fine |
| (b) Restriction on dividends (s.16) | No dividend until the bank has written off preliminary and organisational expenses, share selling commission, brokerage, losses and other capitalised expenses not represented by tangible assets, and made adequate provision to the CBN’s satisfaction for actual and contingent losses, and complied with any capital ratio | A director or officer: not less than three years or a fine of not less than ₦2,000,000, or both |
| (c) Disclosure of interest (s.17) | No director, manager or officer may have a personal interest in any advance, loan or credit facility without disclosing it | Not less than three years or a fine of ₦5,000,000, or both, with forfeiture of any gain |
| (d) Appointments (s.18) | A bank may not keep in employment a person who is or has been bankrupt, has suspended payment or compounded with creditors, or has been convicted of fraud, dishonesty or professional misconduct. It may not be managed by an agent the CBN has not approved, and may not, without CBN approval, have as a director a person who is a director of another bank. A financial holding bank may have up to 30% of its board from subsidiaries and associates | |
| (e) Restriction on certain banking activities | No advance, loan, credit or guarantee to any person above 20% of shareholders’ funds (50% for a merchant bank) without CBN approval in writing. No loans against the security of its own shares, or unsecured loans unless authorised by its rules | |
| (f) Unsecured advances (s.19) | No unsecured advances above ₦1,000,000, without prior CBN approval, to its directors, or to firms or companies in which it or a director is interested, or to public or private companies in which it or its directors hold 5% or more | |
| (g) Merchant banks (s.20) | Must not accept a deposit withdrawable by cheque, accept a deposit below the CBN’s prescribed amount, or hold for over six months an equity interest acquired while managing an equity issue | Fine not exceeding ₦20,000,000 and ₦500,000 a day |
| (h) Interest rates | Display its lending and deposit interest rates at its offices and report them to the CBN | Not less than ₦5,000,000 and ₦100,000 a day |
May 2017 tested the reserve fund (a bank wishing to pay out all its profits as dividends).
The Central Bank of Nigeria
Section 1 of the CBN Act 2007 establishes the CBN as a body corporate with perpetual succession and a common seal that may sue and be sued in its corporate name.
Objects (section 2)
- to ensure monetary and price stability;
- to issue legal tender currency in Nigeria;
- to maintain external reserves to safeguard the international value of the currency;
- to promote a sound financial system in Nigeria; and
- to act as banker to the Federal Government and provide it with economic and financial advice.
Statutory powers
- The sole right to issue notes and coins throughout Nigeria. No government or other person may issue currency notes, coins or tokens payable to bearer on demand that are likely to pass as legal tender (section 17).
- The power to print notes and mint coins, issue, re-issue and exchange them, keep un-issued stocks safe, and destroy notes withdrawn or unfit (section 18).
- The power to buy and sell Nigerian currency, issuing and redeeming it on demand against other currencies eligible for the external reserves (section 26).
- General powers (section 27): to issue demand drafts and other remittances; open accounts for and accept deposits from governments, banks and financial institutions; keep accounts with banks outside Nigeria; act as correspondent or agent for other central banks; and accept securities for custody and buy, sell and collect securities, currencies and credit instruments in Nigeria or abroad.

- Power to require information from persons and institutions about matters affecting the economy (section 33).
Working through the rules
Was the bank right to return the cheque?
| Facts | Result |
|---|---|
| The account has ₦200,000. A regularly drawn cheque for ₦150,000 is presented, with no legal impediment. The bank returns it | The bank is wrong. All four conditions are met |
| The account has ₦50,000, there is no overdraft agreement and a cheque for ₦150,000 is presented | The bank is right. The account is not in funds |
| The cheque is unsigned or does not match the amount in words | The bank may refuse. It is not regularly drawn |
| The customer stopped the cheque, and the bank pays it | The bank is liable to the customer |
May the bank disclose the account?
| Facts | Result |
|---|---|
| A court orders the bank to produce the account records | Yes. Compelled by law |
| The bank reports a suspicious transaction under the Money Laundering Act | Yes. A public duty and a legal duty |
| The bank sues the customer to recover a loan and gives details of the account | Yes. In the interest of the bank |
| The customer authorises his accountant to see his statements | Yes. With the customer’s consent |
| The bank tells a friend of the customer his balance out of curiosity | No. A breach of secrecy |
The reserve fund
A bank earns net profit after tax of ₦40,000,000. Its paid-up capital is ₦100,000,000 and its reserve fund ₦30,000,000. The reserve is less than the paid-up capital, so it must transfer at least 30%: ₦12,000,000. If the reserve were ₦120,000,000, the transfer would be at least 15%: ₦6,000,000. Only then can it declare dividends.
The single-borrower limit
A commercial bank with shareholders’ funds of ₦200,000,000 may not lend more than 20% to one person without CBN approval: ₦40,000,000. A merchant bank with the same funds may lend up to 50%: ₦100,000,000.
Worked problems
Problem 1: Osagie’s cheque
Scenario. Osagie drew a cheque for ₦150,000 for Osula on Kash Bank Plc. The teller returned it unpaid and told Osula to see Osagie. Osula insists the teller tell him the state of Osagie’s account. State three reasons the bank might be wrong to return the cheque, and three reasons it could lawfully disclose the account.
- Wrongful return. The bank is wrong if the account is in funds, or a credit arrangement exists, the cheque is regularly drawn, or there is no legal impediment to payment.
- Disclosure. The bank may disclose where compelled by law, where there is a public duty, where it is in the bank’s own interest, or with Osagie’s consent.
- Advice. The teller was right not to tell Osula about the account, but if the account was in funds the bank must pay Osagie damages for dishonouring a good cheque.
Problem 2: Mrs Nnaji’s new account
Scenario. Mrs Ore Nnaji has opened a bank account and asks what duties she has on her account.
- The duties. To draw her cheques with care and diligence; to give instructions in writing; to notify the bank promptly of suspicious dealings, such as a lost cheque book or a forged signature; and to pay bank charges.
- Advice. She should keep her cheque book safe, and tell the bank at once if a leaf is missing.
Problem 3: the director’s loan
Scenario. A director of a bank arranges a ₦5,000,000 unsecured loan for a company in which he holds 10% of the shares, without telling the bank. Advise.
- The rules. A bank officer may not have a personal interest in any advance or credit facility without disclosing it (section 17). A bank may not permit unsecured advances above ₦1,000,000 to a company in which a director holds 5% or more without CBN approval (section 19).
- Advice. The director commits an offence, liable to at least three years’ imprisonment or a fine of ₦5,000,000, or both, and forfeiture of any gain. The bank is in breach of section 19 unless the CBN approved.

Common mistakes in the exam
- Saying a person who uses a bank occasionally is a customer. He must have an account in his name.
- Saying a bank may disclose an account to anyone. There are four exceptions.
- Forgetting that the bank must pay only if the account is in funds, the cheque is regular and there is no legal impediment.
- Saying a bank must pay a countermanded cheque.
- Confusing the 30% and 15% reserve rates.
- Mixing up commercial and merchant banks. A merchant bank gives corporate finance and advice and cannot take deposits withdrawable by cheque.
- Saying the CBN can print money only with the government’s approval. It has the sole right to issue notes and coins.
- Forgetting that the bank has to care in opening accounts.

Model answers
Show the model answer to Question 11
(a) Banking business. Under section 131 BOFIA it is the business of receiving deposits on current, savings or similar accounts; paying or collecting cheques drawn by or paid in by customers; providing finance, consultancy and advisory services on corporate and investment matters; making or managing investments for any person, digitally or otherwise; and other business the Governor of the CBN designates.
(b) Rights of a bank. To charge reasonable interest and commission on turnover; to use the money deposited with it; to close the account on reasonable notice; to a lien on the customer’s property in its possession; to refuse payment on an improperly drawn cheque; to recall an overdraft; to set off; and to reimbursement of expenses.
(c) Duties of a customer. To draw his cheques with care and diligence; and to notify the bank promptly of suspicious dealings. (He must also give written instructions and pay charges.)
Show the model answer to Question 12
(a) Honouring cheques. The bank must pay the cheque if the customer’s account is in funds, or a credit arrangement has been agreed, the cheque is regularly drawn. There is no legal impediment to payment.
(b) Confidentiality. The bank may disclose where it is compelled by law, where there is a public duty to disclose, where disclosure is in the bank’s interest, or with the customer’s consent.
(c) Separate accounts. Where the customer has agreed to the contrary.
Show the model answer to Question 13
(a) Mr Ade. A bank must not pay a validly countermanded cheque. Delta Bank paid a stopped cheque, so it is liable to Mr Ade for the loss.
(b) The loan. A director may not have a personal interest in any advance, loan or credit facility without disclosing the nature of his interest (section 17). He is liable to at least three years’ imprisonment or a fine of ₦5,000,000, or both, and must forfeit any gain. A bank may not, without prior CBN approval, permit unsecured advances above ₦1,000,000 to its directors (section 19), so the ₦8,000,000 loan breaches the section.
(c) Reserve and dividends. Because the reserve fund is less than paid-up capital, the bank must transfer at least 30% of net profit after tax, which is ₦15,000,000, before declaring any dividend.
It may not pay a dividend until it has written off its preliminary and organisational expenses, commissions, brokerage and losses not represented by tangible assets, made adequate provision to the CBN’s satisfaction for actual and contingent losses, and complied with any capital ratio. A director or officer who breaks the rule faces at least three years’ imprisonment or a fine of at least ₦2,000,000, or both.
(d) Objects of the CBN. To ensure monetary and price stability; to issue legal tender currency; to maintain external reserves to safeguard the value of the currency; to promote a sound financial system; and to act as banker to the Federal Government and give it economic and financial advice.
