The Exchange That Isn't: Interest, Usury, and What a Sovereign Coupon Actually Is
Antal Fekete defined interest in a way that appears nowhere in standard economics: as the price of exchanging income for wealth. A retiree holds wealth but needs income; an entrepreneur generates income but needs wealth. When they trade, both are better off, and the rate of interest is the price at which that trade clears. Fekete's specific formulation goes further — direct conversion of wealth into income is dishoarding, direct conversion of income into wealth is hoarding, and interest is the measure of the improvement that indirect conversion represents over these cruder alternatives. Which yields a startling corollary in his own words: zero interest means direct conversion. Zero interest does not mean cheap money. It means the exchange mechanism has been abolished and every holder of wealth reverts to hoarding. This essay takes that definition and uses it as a test, applied consistently to four transactions that are conventionally grouped together as 'lending': the retiree buying a bond, the entrepreneur issuing one, the household carrying a credit card balance, and the sovereign issuing Treasury debt. The test separates them in ways their common legal form conceals. It also resolves an old puzzle. The medieval and Islamic prohibitions on usury were, by their own theoretical apparatus, unable to distinguish the helpful loan from the oppressive one — a failure the scholarly literature on usury acknowledges directly. Fekete, who opposed the usury prohibition and credited its repeal with creating the bond market, supplies the distinction the prohibition's own defenders could not articulate. This essay develops that synthesis, then applies the resulting test to the mechanics of the $39 trillion national debt — what a coupon actually is, how the weighted average rate of 3.348 percent is constructed, what the roughly $1 trillion in annual interest is actually purchasing, and why the market value of that debt has run roughly $1.27 trillion below par month after month since March 2022 without either side recording it. It closes with the distinction between a citizen and a subject, which is the precise form the sovereignty argument takes once the inflammatory version is set aside.
