The New York Stock Exchange reopened in 1914 after closing during World War I.
The exchange suspended trading on July 31, 1914, as European markets closed and officials feared disorderly selling, gold outflows, and financial instability. The closure was unusual because modern markets normally rely on continuous price discovery rather than an extended shutdown.
A limited bond market reopened in November 1914, while the stock exchange resumed trading on December 12, 1914. The reopening helped establish prices and liquidity after months of uncertainty connected to the war.
This closure is sometimes mistaken for a response to the 1929 crash. The NYSE remained open during the 1929 Wall Street collapse, although it experienced extraordinary trading volume and severe losses. The 1914 shutdown was primarily a wartime financial response.
