We study money creation and destruction in today’s monetary architecture within a general equilibrium setting. Two types of money are created and destructed: bank deposits, when banks grant loans to firms or to other banks, and central bank money, when the central bank grants loans to private banks. We show that symmetric equilibria yield the first-best allocation when prices are exible, regardless of the monetary policy or capital regulation. When prices are rigid, we identify the circumstances in which money creation is excessive or breaks down and how an adequate combination of monetary policy and capital regulation may restore efficiency.
