Question

Explain how market forces would determine the money supply under free banking.

Short answer

Under free banking, market forces of supply and demand determine the money supply. When demand for banknotes increases, banks issue more notes, increasing the money supply. Conversely, when demand decreases, they reduce the supply to maintain the value of their notes. Interest rates, influenced by supply and demand, also play a crucial role by either incentivizing or discouraging lending, consequently affecting the money supply.

Step-by-step solution

Define Free Banking

Free banking refers to a monetary arrangement where banks are free to issue their own paper currency (banknotes) in response to market demands. There is no central banking system or regulatory body, and market forces primarily influence the supply and demand of money.

Describe Market Forces

Market forces, in this context, refer to the forces of supply and demand. The demand for money arises from consumers and businesses who need money for transactions or to hold as a store of value. The supply of money arises from banks that issue banknotes in response to this demand.

Explain the Interaction of Market Forces

In a free banking system, the interaction of demand and supply determines the money supply. When demand for money (banknotes) increases, banks have an incentive to issue more notes. On the contrary, when demand decreases, the excessive banknotes return to the banks and they reduce the money supply. This is because having too many notes in circulation could lead to a decrease in the value of the banknotes, pushing the banks to reduce the supply to maintain their value.

Influence of Interest Rates

Interest rates also play a significant role in determining the money supply in a free banking system. High interest rates incentivize banks to lend more, increasing the money supply, while low interest rates discourage lending, reducing the money supply. The interest rate is also a product of supply and demand; when demand for loans (and thus, banknotes) increases, interest rates rise, and vice versa.
