Role of the central bank in developing economies?

The central bank plays an important role in causing an appropriate adjustment between the demand and the supply of money. An imbalance between the two is reflected in the price level. A shortage of money supply will inhibit growth while an excess will lead to inflation. As the economy develops, the demand for money will likely increase due to the gradual monetization of the non-monetized sector and the increase in agricultural and industrial production and prices.

What is an interest?

Interest is the cost of using someone else's money. When you borrow money, you pay interest. Interest refers to two related but very distinct concepts: either the amount a borrower pays the bank for the cost of the loan, or the amount an account holder receives for the favor of leaving money behind. the bank. It is calculated as a percentage of the balance of a loan (or deposit), periodically paid to the lender for the privilege of using his money. The amount is usually stated as an annual rate, but interest can be calculated for longer or shorter periods than one year.
