How Banks Invent Money Legally

Key Concepts:

• Credit-based economy
• Fractional reserve banking
• M1 and M2 money supply
• Cheap money vs. Expensive money
• Credit arbitrage
• Carry trade
• Debt-fueled speculation

I. The Illusion of Money:

• Main Point: Approximately 90% of the world's money is digital and exists as credit, not physical cash.
• Explanation: The global economy relies on credit to facilitate large-scale projects like building cities and funding governments.
• Example: If person A lends $100 to person B, who lends it to person C, who lends it back to person A, there's only $100 in cash but $300 in debt.
• Trust: The system works because of collective trust that debts will be repaid.
• Bank Loans: Banks create new money digitally when they approve loans, based on the borrower's creditworthiness.
• Withdrawal Rate: Banks operate on the understanding that only about 10% of deposits are withdrawn as physical cash at any given time.
• US Example: The US has approximately $21 trillion in broad money supply, but only $5.5 trillion exists as physical cash.
• System Collapse: If everyone tried to withdraw their money simultaneously, the system would collapse.

II. How Banks Create Money:

• Digital Entry: Banks create new money by making a digital entry (deposit) based on the promise of repayment.
• Loan Approval: When someone takes out a loan, the bank assesses their credit score, income, and debt load to determine the interest rate (cost of money).
• Money Supply Expansion: Banks expand the money supply (M1 and M2) by creating loans.
• Fractional Reserve Banking: Banks are only required to keep a fraction of their deposits as physical cash or central bank reserves.
• US Reserve Requirement: The US Federal Reserve eliminated reserve requirements in March 2020, allowing banks to lend out as much money as they want, provided the borrower is creditworthy and the bank meets its capital ratio obligations.
• Printing Money: "Printing money" actually means creating digital money.

III. Cheap Money and Credit Arbitrage:

• Wealth Indicator: The ability to borrow money cheaply is a sign of wealth.
• Interest Rates: Good credit scores result in lower interest rates (e.g., 3%), while bad credit scores lead to higher rates (e.g., 15-25%).
• Credit Arbitrage: Borrowing at a low rate and investing at a higher rate to profit from the difference.
• S&P 500 Example: Borrowing at 3% and investing in the S&P 500, which has historically returned around 10% annually, creates "free money."

IV. Case Study: Japan's Carry Trade:

• 1980s Boom: Japan's economy boomed with low interest rates and a stable yen.
• Carry Trade: Japanese investors borrowed money at home and invested it abroad, particularly in US assets with higher returns.
• Collapse: By the early 1990s, Japan had an overvalued real estate market, a bloated stock market, and a debt-fueled economy.
• Lost Decade: When asset prices crashed, Japan entered a prolonged period of economic stagnation.

V. Risks and Benefits of Credit:

• Speculation vs. Productivity: Cheap money is beneficial when it fuels productivity but dangerous when it fuels speculation.
• System Stability: The system works as long as people don't demand cash all at once and repay their loans.
• Development Enabler: Credit enables rapid development by allowing countries to invest in infrastructure without waiting to save up the necessary funds.

VI. Conclusion:

• The credit-based economy, while seemingly fragile, is the most efficient way to scale human productivity using money we don't yet have. It relies on trust and responsible lending to function effectively.
• "It's not a perfect system but so far it's the most efficient way we found to scale human productivity using money we don't have yet until somebody comes up with a better way of doing things this is what we've got and it works for the most part."
