San Francisco Curb Exchange
The San Francisco Curb Exchange was a curb stock market in San Francisco. It opened in 1928 after reorganizing the San Francisco Stock and Bond Exchange and the San Francisco Mining Exchange, and it operated at 350 Bush Street, taking over the Mining Exchange building. In 1938, the Curb Exchange was absorbed by the San Francisco Stock Exchange and left the Bush Street building.
Background: In 1927, talks planned a split between a listed market and a curb market in the city’s exchanges, with ideas to name and organize the new markets so unlisted stocks could move to a curb board. The plan was for curb requirements to be similar to New York’s curb market. In December 1927, the Stock and Bond Exchange voted to reorganize and create a new curb market, which would be the city’s third securities market. The new curb market would use the old Mining Exchange building and was expected to start in early 1928. It began operations on January 2, 1928, using unlisted securities from the SF Stock and Bond Exchange. Members of the old exchange joined both the new Stock Exchange and the curb market, and the curb had up to 100 charter members (67 from the old exchange, with others available for sale).
Later history: The Curb Exchange left the Bush Street building in 1938 when it was absorbed by the San Francisco Stock Exchange. The building sat empty after 1979. In 2018, a new 19-story building rose behind the old facade. To preserve history, the front facade was kept, while the rest was rebuilt, including a reconstruction of the old trading hall for visitors to access the office tower.
