The short version
Money is a set of promises denominated in the unit of account. In a modern economy, most of it sits in bank accounts. When a bank makes a loan, it credits the borrower's account with a new deposit. The bank has created money. When the loan is repaid, the deposit is extinguished and the money disappears.
This is not a metaphor. It is how the balance sheet works. The Bank of England's 2014 primer describes it plainly: "Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower's bank account, thereby creating new money."[1]
That single mechanism connects the topics on this site. If credit creation is the engine, then banking, central banking, monetary policy, financial risk, macroeconomics, and deflation are the systems that shape where the engine goes — and what happens when it stalls.
Step 1 — Money creation
Start with the balance-sheet mechanics. A loan creates a deposit; repayment destroys it. Then look at what limits bank lending: demand for credit, capital, liquidity, regulation, and profitability.

Step 2 — The banking system
Banks do more than create deposits. They transform maturity, settle payments, and connect borrowers to savers. That combination is productive, and it is fragile.
Step 3 — The money supply
M0, M1, and M2 measure different layers of money. They are useful indicators, but they are not simple policy levers. The textbook "money multiplier" is a poor description of how modern banks actually operate.
Step 4 — The Federal Reserve and monetary policy
The Fed supplies reserves, sets a policy rate, and acts as lender of last resort. Monetary policy works through interest rates, credit conditions, asset prices, expectations, and the exchange rate. It is powerful, but it is not a joystick.

Step 5 — Risk, macroeconomics, and deflation
Credit creation can support growth. It can also build leverage, maturity mismatch, and debt burdens that make the system vulnerable. The final step connects those risks to macroeconomic outcomes and to the particular problem of deflation.
