Why money is fundamentally debt, how credit pulls future productivity into the present, and how ledgers record social obligations.
What is debt?
Debt is an obligation where one party (the borrower) receives resources today and commits to repaying the lender at a specified future date, typically with interest.
Money is fundamentally debt
A common misconception is that physical money was invented first, and debt came later as a way to borrow money. Historical and anthropological evidence shows the opposite: credit and debt systems existed long before physical coinage was minted.
Ancient Mesopotamian temples and agrarian villages recorded mutual debts and obligations on clay tablets thousands of years ago. The ledger of mutual credit was the medium of exchange.
In modern financial systems, this principle remains completely true: banknotes are liabilities of the central bank, deposits are IOUs of commercial banks, and new money is created when commercial banks extend loans against promises to repay.
