Most people think of a bank as a safe place to keep money. That is true, but it is only part of the story. A bank is also a business, and like any business, its goal is to make a profit. The money you deposit is not simply stored in a vault. It is used — carefully and under strict rules — to generate income for the bank.
Understanding how banks make money from your money is not just a matter of curiosity. It explains why banks charge certain fees, why interest rates on loans are high while savings rates are low, and why banks are so interested in attracting deposits. It also helps you, as a customer, make better decisions about where to keep your money and how to use banking services.
This article explains, in plain language, how banks in Ghana earn income from deposits, loans, fees, and investments. It also clarifies what banks do with your money and what protections exist.
Quick Facts
-
Banks are businesses. They accept deposits and use those funds to make loans and investments that generate income.
-
The difference between the interest a bank pays depositors and the interest it charges borrowers is called the net interest margin.
-
Banks also earn money from fees, commissions, and charges on accounts, transactions, and services.
-
In Ghana, banks invest a significant portion of their funds in government securities such as treasury bills and bonds.
-
The Bank of Ghana requires banks to hold a portion of deposits in reserve, so not all deposited money can be lent out.
-
Deposit insurance protects customers up to a specified limit if a bank fails, but it does not mean banks can take unlimited risks.
The Basic Business Model
A bank’s business model is built on intermediation. The bank sits between people who have money and people who need money. It borrows from depositors and lends to borrowers. The profit comes from the difference between what the bank pays for the money and what it earns from using it.
Imagine a simple example. You deposit GH₵10,000 into a savings account. The bank pays you 5% interest per year, meaning you earn GH₵500. The bank then lends that GH₵10,000 to a borrower at 25% interest, earning GH₵2,500. The difference — GH₵2,000 — is the bank’s gross income from that transaction, before costs.
Of course, the bank does not lend out your specific GH₵10,000 as a separate parcel. It pools deposits from thousands of customers and lends from the pool. But the principle is the same: the bank pays less for money than it charges for money.
The Net Interest Margin
The gap between what a bank pays on deposits and what it earns on loans and investments is called the net interest margin. It is the single most important source of income for most Ghanaian banks.
The net interest margin varies from bank to bank and from year to year. It depends on the level of interest rates in the economy, the bank’s cost of funds, the mix of loans and investments, and the level of competition.
In Ghana, net interest margins have historically been relatively high compared with banks in developed economies. This reflects the high interest rate environment, the cost of doing business, and the risks involved in lending.
How Banks Use Deposits
When you deposit money in a bank, the bank does not keep all of it in cash. It uses the money in several ways.
Reserves
The Bank of Ghana requires banks to hold a certain percentage of their deposits in reserve. The reserve requirement is a tool of monetary policy. It ensures that banks do not lend out every cedi they receive and that they have enough liquid assets to meet withdrawal requests.
The reserve requirement is expressed as a percentage. If the reserve requirement is 10%, a bank must hold GH₵10 of every GH₵100 deposited in reserve. The rest can be used for lending and investment.
Reserves may be held as cash in the bank’s vaults or as deposits with the Bank of Ghana. They earn little or no interest, which is one reason banks prefer to lend rather than hold large reserves.
Loans
The main use of deposits is lending. Banks make loans to individuals, businesses, and government entities. Loans generate the highest returns, but they also carry the highest risk of default.
When a bank makes a loan, it expects to be repaid with interest. The interest rate reflects the bank’s assessment of the borrower’s creditworthiness, the duration of the loan, and the overall interest rate environment.
Loans in Ghana are typically extended for purposes such as business expansion, home purchase, vehicle financing, education, and personal consumption. Banks assess each application and set terms based on the borrower’s ability to repay and the collateral available.
Investments
Banks also invest a portion of their funds in securities, particularly government securities such as treasury bills and bonds. These investments are generally safer than private loans, though they also pay lower returns.
Government securities are attractive to banks for several reasons. They are low-risk relative to private lending. They are liquid, meaning they can be sold if the bank needs cash. And they provide a steady stream of income.
However, heavy investment in government securities also has a downside. It means banks are lending more to the government and less to private businesses. This can crowd out credit to the private sector, as happened in Ghana during periods of high government borrowing.
Interbank Lending
Banks sometimes lend to each other in the interbank market. A bank with excess cash may lend overnight or for a few days to a bank that needs liquidity. These loans are very short-term and are priced at the interbank rate.
Interbank lending helps banks manage their liquidity and meet regulatory requirements. It is not a major source of profit but is an important part of the financial system.
Fees and Commissions
Interest income is not the only way banks make money. Fees and commissions have become increasingly important, especially as competition has put pressure on interest margins.
Account Maintenance Fees
Many banks charge a monthly or quarterly fee for maintaining an account. The fee may be waived if the account maintains a minimum balance.
Transaction Fees
Banks charge fees for certain transactions, such as transfers, withdrawals above a certain limit, and use of banking services beyond the basic ones.
ATM Fees
Using another bank’s ATM often attracts a fee. Even using your own bank’s ATM may be subject to limits and charges.
Mobile and Digital Banking Fees
While many digital services are free, some attract charges. International transfers, some mobile banking transactions, and certain electronic services may involve fees.
Loan Processing Fees
When you take a loan, the bank may charge a processing fee in addition to the interest. This fee covers the administrative cost of evaluating and disbursing the loan.
Foreign Exchange Fees
Banks earn income from foreign exchange transactions. They buy foreign currency at one rate and sell it at a higher rate, keeping the difference as profit. They may also charge a commission on currency exchange.
Other Services
Banks earn income from trade finance, advisory services, asset management, and other specialised services. These are more relevant to corporate and high-net-worth clients.
Why Savings Rates Are Low and Loan Rates Are High
The gap between savings rates and loan rates is a common source of frustration for bank customers. If you deposit money, you earn modest interest. If you borrow, you pay high interest. Why is the gap so large?
Costs
Running a bank is expensive. Branches, staff, technology, security, and regulatory compliance all cost money. These costs must be covered before the bank makes a profit.
Risk
Lending involves risk. Some borrowers will default. The bank must price its loans to cover expected losses. This means charging a premium above what it pays depositors.
Inflation
Inflation erodes the value of money. Lenders demand compensation for this. The high inflation environment in Ghana contributes to high nominal interest rates.
Reserve Requirements
The portion of deposits held in reserve earns little or nothing. To make an adequate return on the total deposit base, the bank must earn more on the funds it does lend.
Competition and Market Power
Competition among banks affects pricing, but banks also have significant market power. In many cases, customers have limited alternatives, and banks can maintain wide margins.
How Banks Make Money from Government Securities
One of the most significant ways Ghanaian banks earn income is by investing in government securities. When a bank buys a treasury bill or bond, it is lending money to the government. In return, the government pays interest.
The rates on government securities are determined at auction and are influenced by the Bank of Ghana’s policy rate, inflation, and the government’s borrowing needs. In Ghana, these rates have often been high, making government securities attractive to banks.
This creates a situation where banks earn substantial income from government debt with relatively low risk compared with private lending. However, it also means that a large share of bank funds is not being used to finance private businesses and households.
The recent domestic debt exchange programme, which restructured government bonds, highlighted the risks of heavy exposure to government debt. Banks that held large amounts of government bonds faced losses when the terms of those bonds were changed.
The Role of the Bank of Ghana
The Bank of Ghana influences how banks make money in several ways.
The Policy Rate
The monetary policy rate is the rate at which the Bank of Ghana lends to commercial banks. It serves as a benchmark for other interest rates. When the policy rate rises, banks tend to raise their lending rates, which can widen or narrow their margins depending on the circumstances.
Reserve Requirements
The reserve requirement determines how much of their deposits banks must hold in reserve. A higher reserve requirement reduces the amount banks can lend and invest, potentially reducing their income.
Supervision
The Bank of Ghana supervises banks to ensure they are sound and well-managed. This includes monitoring their capital, liquidity, and risk management. Banks that are poorly managed may be required to hold more capital or take corrective measures, which can affect their profitability.
Open Market Operations
The Bank of Ghana buys and sells government securities to manage liquidity in the banking system. These operations affect the amount of money banks have available to lend and the rates they charge.
How Depositors Are Protected
Because banks use deposits to make loans and investments, there is always a risk that something could go wrong. To protect depositors, Ghana has a deposit insurance scheme.
The Deposit Protection Scheme, managed by the Deposit Protection Corporation, protects depositors up to a specified limit if a licensed bank fails. The scheme pays depositors their protected funds, reducing the impact of bank failure on ordinary people.
The existence of deposit insurance is important, but it does not eliminate all risk. Depositors with large balances above the protected limit may face losses if a bank fails.
What This Means for You
Understanding how banks make money can help you make better financial decisions.
Shop Around
Banks differ in their fees, interest rates, and services. Comparing options before you commit can save you money and improve your returns.
Understand Fees
Before you open an account or take a loan, ask about all the fees and charges. The annual percentage rate on loans gives a fuller picture than the quoted interest rate.
Consider Alternatives
Banks are not the only place to save. Treasury bills, fixed deposits, and other instruments may offer better returns, depending on your goals and risk tolerance.
Protect Yourself
Keep within the deposit protection limit where possible. Diversify your savings across institutions if you have large balances. Monitor your accounts and statements.
Use Credit Wisely
Borrowing can be useful, but it is expensive. Borrow only when the expected return exceeds the cost, and understand the full cost before signing.
Common Misconceptions
“Banks keep all my money in the bank”
Banks use deposits to make loans and investments. They hold only a fraction in reserve. This is how banking works, and it is why deposit insurance exists.
“Banks make most of their money from fees”
Fees are important, but for most Ghanaian banks, interest income — the margin between deposit and lending rates — is the largest source of revenue.
“The government uses my bank deposit”
The government does not have direct access to your bank deposit. However, banks invest in government securities, which means they lend to the government using pooled funds that include your deposit.
“High lending rates mean banks are greedy”
Bank rates reflect costs, risks, and the overall interest rate environment. While banks do seek profit, the high rates in Ghana are driven by structural factors, not simply greed.
“Deposit insurance means my money is completely safe”
Deposit insurance protects you up to a specified limit. Amounts above the limit may be at risk. The safety of your deposit also depends on the health of the bank.
Frequently Asked Questions
How exactly does a bank use my savings account money?
Your deposit is pooled with others and used to make loans and investments. The bank earns income from these activities and pays you a portion as interest.
Why does my savings account pay so little interest?
Savings accounts pay lower interest because the bank must cover its costs, manage risk, and earn a profit. Fixed deposits and other products may pay higher rates.
Where does the money for my loan come from?
Loans are funded from the pool of deposits the bank has collected, as well as from the bank’s own capital and other borrowings.
Why do banks invest in government securities?
Government securities are relatively low-risk, liquid, and provide steady income. They are a key part of how banks manage their funds.
Can a bank lend out all my deposit?
No. The Bank of Ghana requires banks to hold a portion of deposits in reserve. The rest can be lent or invested.
How do I know my bank is using my money responsibly?
Banks are supervised by the Bank of Ghana and must comply with strict rules on capital, liquidity, and risk. You can also read the bank’s published financial statements.
Should I keep all my money in one bank?
Diversification reduces risk. If your balance exceeds the deposit protection limit, consider spreading funds across more than one licensed institution.
What to Remember
A bank is not just a warehouse for your money. It is a business that earns income by using your deposits to make loans and investments. The difference between what it pays you and what it earns is its profit.
This does not make banks bad. It makes them financial intermediaries. The system works when banks manage money prudently, borrowers repay, and depositors are protected.
The more you understand how banks make money, the better equipped you are to choose the right accounts, avoid unnecessary fees, and make your own money work harder for you.
