# Credit Theory of Money The **credit theory of money** holds that money is not a *thing* but a *relationship*: a transferable record of debt, denominated in a unit of account. A coin, a banknote, or a bank balance is an IOU — a claim on whoever issued it — and its value comes from the issuer's obligation to accept it back, not from any metal it contains or represents. On this view the unit of account comes first, credit comes second, and physical money is a late and incidental token of relationships that already existed. It is the rival to the **commodity (or "metallist") theory**, the textbook story descended from [[Adam Smith]]'s *[[The Wealth of Nations]]*: people first bartered, then settled on a convenient commodity (gold, silver) as a medium of exchange, and credit was built on top of that commodity base later. Which story you believe determines what you think [[Fiat Currency]] is, what banks do, and whether a government deficit is a household going broke or something else entirely — which is why a dry question in monetary theory sits underneath some of the right's most durable economic politics. ## The core claim The canonical statement is by the British diplomat **Alfred Mitchell-Innes** (1864–1950), in two articles in *The Banking Law Journal*: "What is Money?" (May 1913) and "The Credit Theory of Money" (1914). His one-line definition: > "The Credit Theory is this: that a sale and purchase is the exchange of a commodity for credit. From this main theory springs the sub-theory that the value of credit or money does not depend on the value of any metal or metals, but on the right which the creditor acquires to 'payment.'" Mitchell-Innes was a career diplomat, not an academic economist; he wrote the articles at the end of a posting as counselor at the British Embassy in Washington (1908–1913). [[John Maynard Keynes]] gave "What is Money?" an approving review in the *Economic Journal* in 1914. The articles then sank from view for most of the century until heterodox economists revived them; [[L. Randall Wray]] edited the collected work as *Credit and State Theories of Money: The Contributions of A. Mitchell Innes* (2004). Three propositions follow from the core claim: - **Money is a social and legal relation, not an object.** What circulates is a promise. The question "what backs the dollar?" has the same answer whether or not gold is in a vault: the issuer's willingness and ability to accept its own liabilities back. - **Government money is government debt, redeemed through taxation.** Mitchell-Innes argued that a state's currency is valuable because the state accepts it in payment of taxes. This is where credit theory meets **chartalism**, Georg Friedrich Knapp's *State Theory of Money* (German 1905; English 1924) — the "money is a creature of the state" lineage that [[MMT]] (also called Neo-Chartalism) builds on directly. - **Banks create money when they lend.** If money is credit, then a bank making a loan is not handing over someone else's savings; it is writing a new IOU (a deposit) against the borrower's IOU (the loan). This is the banking-level version of the theory, discussed below. ## Two origin stories, side by side | Question | Commodity / metallist theory | Credit theory | | --- | --- | --- | | What is money? | A valuable commodity, or a claim on one | A transferable debt in a unit of account | | Where does its value come from? | Scarcity of the underlying commodity | The issuer's obligation to accept it back; for state money, tax liability | | Historical origin | Barter, then commodity money, then credit | Credit and accounting first; coinage later | | What does a bank do? | Lends out deposits savers have placed with it | Creates new deposits when it makes loans | | What is fiat money? | A debasement — money with nothing behind it | Ordinary money; the gold link was only ever a rule about convertibility | | What is a sovereign deficit? | A household spending beyond its means | The state issuing more of its own IOUs than it taxes back | | Characteristic politics | [[Sound Money]], [[Gold Standard]], [[Austrian School]] | [[MMT]], post-Keynesian and [[Heterodox Economics]] | ## The anthropological case The historical half of the argument was popularized by [[David Graeber]]'s *[[Debt]]* (2011), which leans on Mitchell-Innes and on a century of anthropology to argue that the barter-first sequence has no evidential basis: credit systems and accounting units appear first, in the Mesopotamian temple-and-palace economies, and coinage arrives much later, tied to paying soldiers. Graeber's political move is to show that debt is a power relation dressed up as a moral one ("one must pay one's debts") — a frame that runs straight into [[Austerity]] politics and the bailout asymmetry of the [[2008 Financial Crisis]]. ## The banking version: loans create deposits The credit theory's strongest modern support comes not from heterodox economists but from central banks describing their own plumbing. In its 2014 Q1 *Quarterly Bulletin*, the Bank of England published "Money creation in the modern economy" (Michael McLeay, Amar Radia, and Ryland Thomas of its Monetary Analysis Directorate). Its central points: - "The majority of money in the modern economy is created by commercial banks making loans." - Banks "do not act simply as intermediaries, lending out deposits that savers place with them." - Banks do not "'multiply up' central bank money to create new loans and deposits" — i.e., the textbook **money multiplier** gets the causation backwards. - What limits money creation is the central bank's [[Monetary Policy]] — the price of reserves and, at the zero bound, [[Quantitative Easing]] — plus banks' own profitability and risk constraints. The same year, Richard Werner published an empirical test in the *International Review of Financial Analysis* (vol. 36, 2014), tracing an actual loan through a cooperating bank's books, and concluded: "This study establishes for the first time empirically that banks individually create money out of nothing." The U.S. elimination of formal reserve requirements in March 2020 (see [[Bank Reserves]]) made the deposit-multiplier picture even less descriptive of American practice. This matters for the KB because the vault's own [[Fractional Lending]] entry still opens with the textbook multiplier story. The two accounts agree that banks create money; they disagree about the *direction* — whether deposits fund loans (commodity intuition) or loans create deposits (credit theory). The second is now the operational description central banks themselves give. ## Why it matters for the KB **1. It is the counter-frame to sound-money politics.** The entire [[Hard Money Politics]] lineage — the anti-New Deal gold faction, [[Executive Order 6102]] grievance, [[Ron Paul]]'s "End the Fed," the [[Nixon Shock]] as the moment the dollar became "fake" — rests on the commodity theory. If money *is* gold, or ought to be, then [[Fiat Currency]] is debasement and the [[Federal Reserve]] is a counterfeiting operation. Credit theory denies the premise: money was always a promise, gold convertibility was a policy rule about redeeming the promise, and the end of the [[Bretton Woods System]] changed the rule rather than the nature of money. **2. It reframes the "fractional reserve is fraud" charge.** The [[Austrian School]] critique holds that depositors believe their money is in the bank when it has been lent out. Credit theory says the picture is wrong in both directions: the bank never had a pile of savers' money to lend, because the loan created the deposit in the first place. That defuses the fraud framing — and replaces it with a more uncomfortable fact for everyone, which is that most money is issued by private banks under public license. **3. It undercuts the household-budget analogy.** "The government has to balance its checkbook like every family" is a commodity-money intuition: a family cannot issue the currency it spends. Credit and state theory says a currency-issuing government is in a different position, and that the binding constraint is real resources and [[Inflation]], not running out of money. That premise is the load-bearing beam of [[MMT]]'s challenge to [[Starve the Beast]], to [[Debt Ceiling]] brinkmanship, and to deficit-crisis framing of the [[Federal Deficit and National Debt]]. **4. It explains the crypto irony.** [[Bitcoin]] is an attempt to rebuild commodity money in software: fixed supply, no issuer, nobody's liability. But the instruments that actually function as money in crypto markets are [[Stablecoin]]s — privately issued dollar IOUs, which is to say pure credit money. And the crypto lenders that collapsed in 2022 reinvented bank-style credit creation without the backstops. The market keeps rebuilding credit money even inside the movement built to escape it. The same lens clarifies [[CBDC]] fears: a CBDC changes *who* issues the IOU and who can see it, not whether money is a liability. > [!warning] Hold the frame loosely > Credit theory describes what money *is*; it does not, on its own, settle what governments *should* do. Many mainstream economists and central bankers accept the loans-create-deposits description while rejecting [[MMT]]'s policy conclusions — the inflation constraint is real, and a currency issuer that ignores it can still wreck its currency. Commodity-theory defenders also point out that metallic coin did circulate widely for long periods and that high-inflation episodes are the historical record's case against unconstrained issuers. The useful claim for the KB is narrower: the sound-money moral vocabulary ("honest," "debased," "fake money") presupposes a theory of money that most of the people who actually run the monetary system do not hold. ## See Also - [[MMT]] — the policy school built on the state-money branch of the theory - [[Debt]] and [[David Graeber]] — the anthropological case against the barter myth - [[Fractional Lending]] and [[Bank Reserves]] — the banking mechanics, told from the textbook side - [[The Banking System]] and [[Monetary Policy]] — the institutional setting - [[Sound Money]], [[Hard Money Politics]], [[Gold Standard]] — the commodity-money tradition this page argues with - [[Austrian School]] — the academic home of the commodity view and the fraud critique of fractional reserve - [[Fiat Currency]] — the antagonist in the sound-money frame; ordinary money in this one - [[Financial System Hub]] — the institutional map
