A person can now buy shares on a phone while queuing for coffee. The scene is oddly fitting, because the first trading in London happened over coffee too.
The idea behind a stock market is old and plain. One person has an enterprise, another has money, and the market is where they agree to split the risk.
Shares in a ship
Most accounts start in the Dutch Republic in the early 1600s. In 1602 the Dutch East India Company sold shares to the public, and buyers could then trade those shares among themselves in Amsterdam. Ordinary investors suddenly had a stake in global commerce without having to fit out a ship, hire a crew or face pirates and storms.
London built its own financial culture, and much of it grew up in coffee houses rather than banking halls. By the late 1600s brokers, merchants and speculators crowded into places like Jonathan’s Coffee House, where prices for stocks, commodities and currencies were posted. Part of the early story of the London Stock Exchange belongs to that world of gossip, credit and coffee.
Bubbles and panics
The danger came early. Britain’s South Sea Bubble, in the early 1700s, saw investors rush into the South Sea Company, sure that trade with Spanish America would make them rich. Prices climbed far past reason and then fell apart.
In America, markets formed around government debt, banks and insurers, and the commercial pull of New York. In 1792 two dozen brokers signed the Buttonwood Agreement, the founding document of what became the New York Stock Exchange. It set rules and commissions for trading securities. Wall Street, named for an actual wall from the Dutch colonial period, slowly became the center of American finance.
In the 1800s, stock markets helped pay for railroads, factories, mines and telegraphs. They also produced panic after panic, many of them tied to railroads, land speculation and shaky banks.
1929 and what followed
Then came the crash. In October 1929, after the Roaring Twenties, the Dow Jones Industrial Average fell nearly 13 percent on Black Monday alone. The crash did not by itself cause the Great Depression, but it laid bare weak spots in banking, credit and regulation. For a generation, stocks meant ruin rather than easy wealth.
Reform followed. The United States created the Securities and Exchange Commission and tightened disclosure rules. Investors who once leaned on tips and private clubs gradually gave way to a world of prospectuses, audited statements and professional analysts.
After the Second World War, pension funds, mutual funds and later index funds drew millions of ordinary people in, indirectly. Owning stock became part of retirement planning and household wealth, not just a pastime of financiers and industrialists.
The late twentieth century added speed: computerized trading, global exchanges, derivatives and round-the-clock financial news. The crash of 1987, the dot-com bubble, the 2008 financial crisis and the swings of the pandemic years each showed the same thing. The machinery changed, but fear and greed did not.
Today trades settle in fractions of a second, and algorithms shape much of the flow.
