Market Crash of 1997: Stocks Plummet, Circuit Breakers Triggered

Stock markets worldwide plunged on October 27, 1997, when the Dow Jones Industrial Average dropped 554.26 points to close at 7,161.15, triggering emergency measures that had never been used in the history of the New York Stock Exchange. The crash was driven by contagion from the Asian financial crisis that had begun in Thailand in July, spread to Indonesia, South Korea, and Malaysia, and by late October was threatening to engulf global markets. Investors panicked over the possibility that Asian economic instability would spread to Latin America and Europe, and selling accelerated through the morning as margin calls forced leveraged funds to liquidate positions at any price. The NYSE activated its circuit breaker mechanism twice during the trading session, halting trading first when the Dow fell 350 points and again at the 550-point threshold, at which point exchange officials made the controversial decision to close the market early. It was the first time circuit breakers had been deployed since their creation following the 1987 crash. The early close prevented further losses but raised questions about whether halting trading in a panic actually reduces volatility or merely delays it. Markets stabilized the following day after bargain hunters moved in and Federal Reserve Chairman Alan Greenspan signaled that the Fed stood ready to provide liquidity. The episode forced regulators and exchange officials to reevaluate circuit breaker thresholds and confront the speed at which electronic trading could amplify fear across interconnected global markets.
