History of Finance as a Business

American finance was not designed either. Like American healthcare, it grew in layers, and each layer answered a problem the previous one had left behind. Alexander Hamilton built a national bank and a market for federal debt; Andrew Jackson killed the bank; a generation of state "free banks" issued their own notes; the Civil War produced national charters; and J. Pierpont Morgan became the country's unofficial central bank until the Panic of 1907 proved that one man could not be. The crash of 1929 and the bank failures that followed produced the most durable layer of all: deposit insurance, the SEC, and the wall between commercial and investment banking that lasted until 1999. The 1970s broke that system open. Inflation and money-market funds drained the banks, fixed brokerage commissions ended, Vanguard sold the first retail index fund, securitisation turned mortgages into bonds, and credit cards turned consumer lending into a national data business. Deregulation and consolidation built the giant universal banks that nearly collapsed in 2008, and the rules written afterwards pushed lending and trading into non-banks, fintechs and private credit. This section traces that sequence from the Medici to the stablecoin, explains the business models each era produced and the patterns that keep coming back, and shows why knowing the history makes it easier to tell a real structural change from a rebranding.
