# Debt-Based Monetary System

## Definition

A fiat system where currency is created simultaneously with debt issuance, requiring continuous expansion of debt to service existing interest.

## The 1971 Inflection

Moss anchors the entire framework on **1971** — the year the U.S. ended Bretton Woods gold convertibility, severing the dollar from any physical anchor. From that moment forward, the world has operated on a pure fiat, debt-based monetary system.

Under this system, money is **not a representation of stored labor or a physical commodity**. It is created into existence simultaneously with debt:

- A bank issues a mortgage → new money is added to the supply.
- A bank issues a car loan → new money is added to the supply.
- A government issues a bond bought by the Fed → new money is added to the supply.

See [[quote-money-supply-debt]] for Moss's pithy formulation: *'The very fact that the money supply is increasing means that the debt grew because that's how the money was created.'*

## The Structural Trap

Because debt carries interest, there is always **more debt in the system than money to pay it off**. The arithmetic gap can only be closed by issuing more debt — which creates more money — which is again insufficient. This produces:

- Permanent inflation (the [[concept-debasement-trade]] is the rational response).
- An exponential trajectory in total debt outstanding.
- A built-in fragility: stop expanding credit and the system deflates catastrophically.

This is the mechanism behind [[claim-fiat-continuous-printing]] — money printing is a mathematical necessity, not a political choice.

## Open Question

What is the **endgame** of this exponential progression? Moss does not predict the timing, but he frames the question explicitly in [[question-debt-endgame]].

## Prerequisite

Readers unfamiliar with how commercial bank lending creates broad money should start with [[prereq-fiat-money-creation]].

## Mainstream Nuance

Commercial bank lending is indeed the dominant driver of broad money expansion. However, the strict claim that the system *cannot* survive without exponential growth ignores debt restructuring, default, fiscal consolidation, and inflation-driven debasement of real debt loads — all of which mainstream debt-sustainability literature treats as feasible escape valves.
