Q & A

What is 'book money' and how does it differ from physical cash?

'Book money' (Buchgeld) refers to the digital representation of money held in bank accounts, while physical cash consists of coins and banknotes. Book money exists in electronic form and is created through banking transactions.

How do banks create new book money?

Banks create new book money primarily through the issuance of loans. When a bank grants a loan, it credits the borrower's account, effectively increasing the amount of book money in circulation.

What happens to book money when a loan is repaid?

When a loan is repaid, the corresponding amount of book money is removed from the borrower's account, effectively destroying that portion of the money supply.

How does the interest rate affect the creation of book money?

Interest rates directly influence the demand for loans. Higher interest rates tend to discourage borrowing, resulting in less new book money being created, while lower rates can encourage borrowing and increase book money supply.

What role do central banks play in the money supply?

Central banks, such as the European Central Bank, regulate the money supply by setting interest rates and implementing monetary policies that influence lending by commercial banks.

Can book money be created without issuing loans? If so, how?

Yes, book money can also be created when banks purchase assets, such as stocks or real estate, from customers. The purchase amount is credited to the seller's account, thus creating new book money.

What are some factors that influence banks' ability to create book money?

Factors include the demand for loans in the economy, prevailing interest rates, the creditworthiness of borrowers, regulatory requirements from banking authorities, and the risk assessments performed by banks.

What happens when banks sell assets to customers?

When banks sell assets to customers, the purchase amount is deducted from the customer's account, reducing the amount of book money in circulation.

How do banks manage risks associated with lending?

Banks assess the credit risk of borrowers to determine their ability to repay loans and cover interest. They also monitor costs associated with loan issuance and potential losses from defaults.

What impact does the creation and destruction of book money have on economic growth?

The creation of book money can stimulate economic growth by providing businesses with access to credit for investments, while the destruction of book money (e.g., through loan repayments) can slow down economic activity.
