Credit and Debt

Anthropological and archaeological evidence suggests that credit -- the extension of goods or services on the promise of future reciprocation -- predates coined money by millennia. The cuneiform tablets of Mesopotamia, dating to around 3000 BCE, are credit records: they document debts owed in silver or grain, accruing interest, transferable between parties, and enforceable by temple and palace authorities. If money is a way of recording obligations, then debt is not money's shadow but its original form (Graeber, 2011).

This primacy of credit has important implications for how we understand banking. Banks do not, as is commonly assumed, take in deposits and then lend them out. The Bank of England has stated explicitly that "whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's bank account, thereby creating new money" (McLeay et al., 2014). Credit creation is money creation. Every mortgage, business loan, and credit card advance brings new money into existence -- and the repayment of that debt destroys it. The money supply is not a fixed reservoir managed by the central bank; it is a dynamic flow shaped by lending decisions made by thousands of commercial banks in response to economic conditions and regulatory constraints.

The idea that banks lend out deposits they have received is one of the most persistent misconceptions in economics. Banks create deposits when they lend, not after.Bank of England Quarterly Bulletin, Q1 2014

Debt also carries moral weight that its purely economic function does not explain. In many languages, the words for debt and guilt share a common root. David Graeber (2011) documents how debt has been used historically to discipline populations: the moral imperative to repay creates a compliance mechanism that pure market logic cannot supply. Entire nations have been bound by debt obligations that, on any realistic analysis, they could not repay -- and the insistence that they try imposed enormous costs in poverty, unemployment, and social disruption (Reinhart and Rogoff, 2009).

The 2008 financial crisis brought the role of debt in money creation into sharp public focus. The crisis originated in a vast expansion of mortgage credit -- new money -- that had been bundled, securitized, and distributed throughout the global financial system under the assumption that housing prices could not fall nationally. When they did, the credit contraction that followed was a money contraction: asset values collapsed, lending froze, and the real economy contracted as the monetary system that sustained it shrank. Understanding credit as money creation clarifies why financial crises are not merely financial events -- they are monetary events with immediate consequences for employment, income, and human welfare.
