Money Creation and Banking

Understanding how money is created is the foundation of economic literacy, and the textbook story is almost entirely wrong. Most economics courses still teach that banks collect deposits from savers and lend them out to borrowers, multiplying the money supply through a mechanical "money multiplier" process controlled by the central bank's reserve requirements. This model has been explicitly rejected by the Bank of England, the Bundesbank, and other central banks. The reality is that banks create money when they lend, and the causal direction runs from loans to deposits, not from deposits to loans.

The credit theory of money, developed by economists including A. Mitchell Innes, John Maynard Keynes, and later the post-Keynesian tradition including Hyman Minsky and Basil Moore, holds that money is fundamentally a credit relationship. When a bank makes a loan, it creates a deposit in the borrower's account and simultaneously creates an asset on its own balance sheet. No prior savings are needed. No reserves are lent out. The bank creates new purchasing power from nothing, constrained only by its willingness to lend, the borrower's willingness to borrow, and regulatory capital requirements. This is endogenous money creation: the money supply is determined by credit demand in the economy, not by the central bank's reserve policy.

Government money creation works through a parallel but distinct channel. When the government spends, the Treasury instructs the central bank to credit bank accounts, adding reserves to the banking system and deposits to the recipients' accounts. When the government taxes, the process reverses: reserves and deposits are destroyed. Neither bank lending nor government spending involves "finding" money from somewhere else. Both processes create new money and destroy it when the corresponding obligations are met.

The research collected here covers the mechanics of money creation by both commercial banks and governments, the history and critique of the money multiplier model, and the implications for monetary policy. Understanding banking is not a technical footnote. It is the key to understanding why the conventional wisdom about government finance, from "taxpayer money" to "borrowing from future generations," is built on a foundation that does not exist.
