The Life Cycle of Money explains how modern currency operates as a balance sheet relationship rather than a physical commodity. Money exists in three forms: base money (central bank liabilities), broad money (commercial bank deposits), and credit money (claims on future output). This framework reveals that money is created through accounting entries, not printing presses.

Understanding the distinction between money, credit, debt, and capital is crucial. While money serves as a universal medium of exchange, credit becomes money only when accepted as payment. Every monetary unit has a corresponding debt claim somewhere in the system. The Federal Reserve and Treasury operate under a legal framework where fiscal authority (spending) rests with Congress while monetary authority (interest rates) belongs to the central bank.

The Treasury General Account at the Federal Reserve serves as the government's operating account, receiving tax receipts and funding spending. When the Treasury spends, it draws on this account, transferring reserves to recipient banks. This process injects deposits into the economy while recycling reserves back into government debt. The system's stability depends on institutional credibility and market depth, not physical backing, making it fundamentally different from historical commodity-based currencies.
