No U.S. presidential proclamation gave the 1929 Wall Street Crash its “Black Tuesday” name.
“Black Tuesday” is a later descriptive label for October 29, 1929, when massive selling struck the New York Stock Exchange. The phrase belongs to newspaper and historical usage, not to an official legal designation issued by the president.
The crash occurred during Herbert Hoover’s presidency, but the White House did not formally name the trading day. The broader sequence is commonly described through Black Thursday on October 24, Black Monday on October 28, and Black Tuesday on October 29.
This distinction matters because dramatic historical labels can sound official even when they are informal. The Securities Act of 1933 and Securities Exchange Act of 1934 were later federal responses to market abuses and investor-protection concerns; neither named the 1929 crash day.
