The common annoyance of banks not paying interest on checking accounts stems from history. Regulators once prohibited it to ensure bank stability. After the rule was repealed, the interest-free float had become such a large and reliable profit center that banks became structurally reliant on it.

Regulation E, a 1979 law, legally mandates that financial institutions bear liability for unauthorized electronic fund transfers. This forces banks to create robust, consumer-friendly dispute systems like chargebacks, making them appear responsive when they are simply complying with strict federal rules that protect consumers.

America's system of nearly 10,000 banks is not a market inefficiency but a direct result of the founding fathers' aversion to centralized, oligopolistic British banks. They deliberately architected a fractured system to prevent the concentration of financial power and to better serve local business people, a principle that still shapes the economy today.

Core components of today's financial landscape, including FDIC insurance, Social Security, and even the 30-year mortgage, were not products of gradual evolution. They were specific policies created rapidly out of the financial ashes of the Great Depression, demonstrating how systemic shocks can accelerate fundamental structural reforms.

Arthur Laffer frames the creation of the Fed as the government taking over a previously private monetary system. He notes that from 1776 to 1913, with a private money system, long-term inflation was zero. Since the Fed's creation, the price level has risen 35-fold, demonstrating the instability introduced by government control.

While many point to ending the gold standard in 1971, the true catalyst for modern economic problems was the 1913 creation of the central bank. This act laid the foundation for the systemic debt creation and currency debasement that fuel today's inflation and inequality.

Central banks evolved from gold warehouses that discovered they could issue more paper receipts (IOUs) than the gold they held, creating a fraudulent but profitable "fractional reserve." This practice was eventually co-opted by governments to fund their activities, not for economic stability.

In a free market, a single bank that over-prints money faces a bank run and fails. The Federal Reserve was established as a cartel to solve this "problem" for bankers. It allows all member banks to expand the money supply in unison, propped up by government backing.

A deposit's value doesn't depend on the performance of the bank's specific underlying assets (like a particular mortgage). This insensitivity to private information is what makes them function like money. When this breaks, as with SVB, the deposit ceases to be money and becomes a risky claim you must analyze.
