Banks get the money that customers borrow from a variety of sources, which form the foundation of their lending activities.
Here’s how banks in Zambia and elsewhere typically generate the funds they lend to borrowers:
1. Customer Deposits
- Savings and Checking Accounts: The primary source of funds for banks is the money deposited by their customers in savings and checking (current) accounts. When individuals and businesses deposit money into their bank accounts, the bank pools these funds and uses a portion of them to issue loans.
- Fixed Deposits: Fixed or term deposits, where customers agree to leave their money in the bank for a set period, provide banks with more stable and longer-term funds that they can use for lending.
Although the deposits remain the property of the customers, banks are able to lend out a significant portion of these funds because depositors usually do not withdraw all of their money at once.
2. Interbank Lending
- Banks can borrow money from other banks in the short-term lending market. If a bank has excess liquidity, it may lend to other banks that need additional funds to meet their lending needs. These interbank loans are typically for very short periods (overnight or a few days) and help banks manage their liquidity and capital needs.
3. Central Bank Loans
- Borrowing from the Bank of Zambia: Commercial banks can borrow money directly from the Bank of Zambia, which acts as the lender of last resort. The central bank lends money to banks through mechanisms like the discount window or repurchase agreements (repos). The central bank charges interest, often referred to as the policy rate, which influences the cost of borrowing for commercial banks and, ultimately, the interest rates charged to customers.
- Reserve Requirements: Banks are required to keep a portion of their deposits as reserves at the central bank. The Bank of Zambia controls the amount banks must keep as reserves, affecting the funds available for lending.
4. Issuing Bonds and Debentures
- Banks can raise funds by issuing bonds or other debt instruments to investors. These bonds are sold to institutional or individual investors who provide capital to the bank in exchange for periodic interest payments. The money raised from bond issuance can be used to lend to customers or finance other banking operations.
5. Shareholder Equity
- The capital contributed by the bank’s shareholders also serves as a source of funds. Banks use shareholder equity (the money invested by owners or stockholders) to support lending activities. This equity acts as a buffer that allows banks to absorb losses and meet regulatory capital requirements.
6. Loan Repayments
- As customers repay their loans, including both principal and interest, the bank receives fresh funds that it can recycle into new loans. A portion of the interest earned from these loans is used to cover the bank’s operational costs and generate profit, while the rest can be lent out again.
7. Profits from Investments
- Banks often invest their own funds in financial instruments like government bonds, treasury bills, and stocks. The income generated from these investments provides additional liquidity, which the bank can use for lending or other banking services.
8. International Borrowing
- In some cases, banks may borrow funds from international financial institutions, such as development banks or international lenders, particularly when local funding is insufficient or when they need to diversify their sources of capital. These funds can then be used for lending to businesses or for large infrastructure projects.
9. Securitization
- In more advanced banking systems, banks may bundle existing loans (like mortgages) and sell them to investors as securities. This process, known as securitization, allows the bank to raise immediate funds, which can then be lent out again.
Conclusion
Banks get the money they lend from a combination of customer deposits, loans from other banks and the central bank, issuing bonds, shareholder equity, loan repayments, and investment profits. By pooling these funds, banks can provide loans to individuals, businesses, and governments, helping to fuel economic activity. The careful management of these funds, along with regulatory oversight, ensures that banks have enough liquidity to meet the withdrawal demands of depositors while still lending profitably.
