Questions & Answers

Q: What is the main role of central banks in market-based economies?

The main role of central banks is to have the authority to create and control the money supply in the economy. They print physical or electronic money and put it into circulation.

Q: How do central banks put newly created money into circulation?

Central banks typically buy safe securities, such as government debt, from the open market using the newly created money. This process injects money into the economy as the sellers of the securities receive the newly printed money.

Q: How does newly created money enter the banking system?

The money enters the banking system when it is deposited in private banks. Individuals or entities who have received the money can either spend it or deposit it in a bank.

Q: What is fractional reserve lending?

Fractional reserve lending is a system where banks are allowed to keep only a fraction of the deposited reserves and lend out the rest. It enables banks to create money through lending while promising customers that their deposits are always available.
