Usury is not merely a technical feature of finance. It is the practice of lending money at interest - all forms of interest. It is a mechanism that, over time, reorders the moral and economic life of entire societies. In ancient economies, usury was recognized as a form of bondage. Today, it is treated as a neutral instrument of progress. But its effects are neither neutral nor accidental. Usury restructures time, labor, and ownership. It trains populations to live in permanent obligation. It consolidates capital into fewer hands. And ultimately, it consumes the society that tolerates it.
At its most basic level, usury transforms money from a medium of exchange into a self-replicating claim on future production. In a debt-based monetary system, new money is created not by productive labor but by issuing credit. Banks do not merely lend existing deposits; they expand the money supply when they extend loans. The borrower receives purchasing power but incurs an obligation to repay both the principal and the interest. This simple fact-more must be repaid than was created - generates a structural demand for perpetual growth. If borrowing stagnates, defaults increase. If defaults increase, the system contracts and begins to unravel.
This expansionary logic produces predictable consequences. As credit proliferates, asset prices rise to absorb the new money. Housing, education, and healthcare become increasingly unaffordable except by incurring additional debt. Wages rarely keep pace with the inflation this process generates, and the household that once could own its home and pass on an inheritance must now borrow simply to remain in place. The longer this persists, the more purchasing power flows away from those who produce and toward those who hold financial claims. This is not an incidental byproduct - it is the core mechanism by which usury operates.
Some will argue that interest-bearing loans are indispensable for economic development, that credit enables entrepreneurship and growth. In part, this is true: in moderation, credit can fund productive enterprise. But over time, the incentive to lend for consumption or speculation rather than genuine investment becomes overwhelming. Lending secured by real collateral and repaid through production gradually gives way to lending that simply pulls demand forward. Eventually, the economy becomes addicted to refinancing old obligations rather than creating new wealth. This is not the dynamic of stewardship but the architecture of dependency.
It is here that the moral dimension becomes unmistakable. Scripture teaches plainly: “You shall not charge interest to your brother” (Deuteronomy 23:19) and condemns false measures that enrich one party through the hidden theft of another (Proverbs 11:1). Debt imposes real constraints on human agency. The man in debt must prioritize repayment over vocation, family, or community. His time and energy are pledged to creditors. Over years and decades, this posture becomes a habit of the soul: reactive, anxious, and dependent.
Aristotle described the “natural slave” as the man who lacks foresight and cannot govern his own life by reason. While Scripture does not teach that any man is born for bondage, it does warn that certain patterns of life will produce it. The borrower who lives beyond his means - who consumes today what he has no reasonable prospect of repaying - eventually becomes the servant of those who lent to him. Usury formalizes this process. It offers the illusion of prosperity while cultivating a culture of high-time preference and perpetual obligation.
These moral and economic dynamics serve a larger current of centralization. Bertrand de Jouvenel observed that Power expands by promising to liberate individuals from intermediary authorities, only to subordinate them more completely to itself. Usury performs this same function economically. When applied to foreign nations and external markets, it can enrich the domestic economy by drawing wealth inward as tribute. But when it turns inward, it becomes an ouroboros, consuming the very base it once relied upon. What began as an engine of expansion becomes an instrument of hollowing.
In a society built upon usury, the broad ownership of land and capital erodes. Small proprietors sell assets to service debt. Productive enterprises are consolidated into larger institutions. A managerial rentier class emerges, whose wealth is secured not by stewardship or productive labor but by the possession of financial claims. The citizen-proprietor is replaced by the wage debtor. What was once an economy of households becomes an economy of functions, each interchangeable and disposable.
Against this backdrop, it is tempting to assume that any alternative must be either utopian or regressive. Yet Scripture does not offer merely a spiritual ideal. It prescribes an economic model whose mechanics are neither naive nor impractical. The laws governing Sabbath rest and Jubilee are designed precisely to arrest the corrosive tendencies of perpetual debt and usury.
It is tempting to imagine that debt forgiveness is little more than charity, a sentimental concession. Yet in Scripture, periodic debt release is presented as a structural safeguard. Far from undermining stability, it is what preserves it over generations. A society that permits interest-bearing debt without temporal constraint will, over time, see wealth concentrate among creditors. Each cycle of borrowing and repayment shifts property upward, as defaults result in foreclosure and productive assets pass into the hands of those who lend rather than those who labor. If no boundary interrupts this dynamic, the process culminates in widespread dispossession: a rentier class secured by law and custom, and a debtor class resigned to permanent tenancy.
Jubilee interrupts this trajectory before it consumes the society that tolerates it. By canceling debts and restoring land to its original families, it resets ownership of productive assets. It extinguishes obligations that have outgrown the debtor’s capacity to repay - not because of moral failure, but because of the inevitable outworking of compounding interest. It reestablishes the material basis for independent livelihoods, so that households can again invest in their holdings rather than serving obligations that will never be satisfied.
This pattern disciplines credit without abolishing it. A creditor who knows that claims will not extend indefinitely has little incentive to engage in predatory lending. It restores the communal dimension of lending, from one neighbor to another as an act of grace. Because the act of lending is a communal one, the premium shifts back to productive investment rather than the passive accumulation of rent. Jubilee also reduces the incentive for speculation by ensuring that gains achieved purely through leveraging the desperation of others cannot be perpetuated beyond a fixed horizon.
The effect is not merely moral but economic. Debt release prevents the emergence of a class whose consumption and production are perpetually depressed by obligations inherited rather than incurred. It sustains the solvency of households, which in turn sustains the solvency of the community. The rhythm of debt and release maintains an equilibrium that modern economies - addicted to perpetual leverage - cannot replicate without periodic crises of default, inflation, or revolution.
In this sense, the biblical model is not opposed to economic reasoning. It is its refinement. It concedes that debt is sometimes necessary and often useful. It recognizes property and the incentives that arise from it. But it also insists that no claim on another man’s future should be permitted to become hereditary or absolute. By drawing this boundary, it preserves not only individual liberty but the long-term stability of the entire economic order.
Over time, this contrast becomes impossible to ignore. Debt economies depend on constant growth. When birth rates decline, governments and corporations import new populations to sustain consumption and service obligations. This is not driven primarily by compassion or ideological commitment. It is the logical conclusion of a credit system that cannot tolerate demographic contraction. People are reduced to interchangeable inputs. Cultural continuity is subordinated to aggregate demand. The inheritance of place and tradition dissolves under the logic of perpetual expansion.
At the same time, the debt economy accelerates the very demographic decline which threatens to reduce its critical consumer base. Rising costs and stagnant wages make it impossible for families to survive on a single income. What began, allegedly, as the pursuit of equality becomes a compulsion of necessity. Wives and mothers enter the workforce to maintain a standard of living their grandparents achieved on one income. Childbearing is delayed or abandoned altogether, not necessarily because of some sudden loss of will, but because debt has made children a liability.
This is the full architecture of dependency. It extracts. It consolidates. It replaces. It consumes. And eventually, it collapses. Ironically, as automation advances and capital concentrates, the system has less and less need of the people it once relied upon to produce. What remains is a shrinking class of managers and an expanding class of dependents - clients of the state, renters of property they will never own. Laborers whose wages, devoured by the importation of cheap widgets (i.e., immigrants) and automation can no longer service their debts. Capital desires lower wages for its workforce, but the workforce doubles as its consumer base. The continual thinning of this consumer base drives capital inexorably toward system collapse.
When this collapse arrives, it will not be because of sudden catastrophe but because of the internal logic of a system that has devoured its own foundation. The question that remains is not whether the debt economy will fail, but what will replace it. Will the next order be built by those who understand the principles of stewardship, or by those who will repeat the same errors under new slogans?
The rejection of usury is not merely a moral gesture. It is the necessary precondition for any society that aspires to freedom. A people who will not constrain debt will be governed by it. A people who will not anchor their economy in real productivity and inheritance will be ruled by those who manufacture credit. The restoration of economic sanity - and of a culture fit for free men - will begin not with innovation, but with the recovery of a conviction: that no man is entitled to harvest what he did not sow, and that no society can endure the permanent subordination of work to credit.
