What was the worst Dow drop ever?

Written by Editorial Team | Last Updated: August 2026

The largest single-day point drop in the history of the Dow Jones Industrial Average occurred on March 16, 2020, when the index plummeted by an astonishing 2,997.10 points, representing a drop of nearly thirteen percent. This historic collapse was driven by mounting panic and economic paralysis caused by the rapid escalation of the COVID-19 pandemic and widespread government-mandated lockdowns. When measured by percentage loss, however, the worst single-day crash remains Black Monday on October 19, 1987, when the Dow plunged by a staggering 22.6 percent in a single trading session due to portfolio insurance failures and runaway selling pressure.
