Answer:
Banks make a profit from interest rates.
Step-by-step explanation:
The interest rate is the amount of interest that borrowers pay for the use of money over a period of time. The interest rate is expressed as a percentage of the loan amount.
The main lender is the central bank, which sets an interest rate on the currency it issues, which is the base rate for institutions that borrow from the central bank. Banks that have borrowed from the central bank must take into account the costs involved and the expected profit. For this reason, the bank's interest rate is higher than that of the central bank. The basis for borrowing for individuals and companies is the interest rate set by the bank. Should an individual or company have to sub-lend its loan, the next borrower must follow the interest rate set by the individual or company.
