Which Vienna exchange event on May 9, 1873, helped trigger the Panic of 1873?

The Vienna stock market crash on May 9, 1873, helped trigger the Panic of 1873.

The Vienna exchange collapse followed years of speculative investment and rapid expansion after the Austro-Hungarian Compromise of 1867. Investors had poured money into banks, railways, and construction projects, and confidence weakened when expected profits failed to appear.

The crash spread financial fear through Europe and then across the Atlantic. In the United States, the failure of the banking firm Jay Cooke & Company in September 1873 helped produce a major banking panic and a temporary closure of the New York Stock Exchange. The resulting depression lasted for years in several countries.

The panic had multiple causes, including excessive credit, railway speculation, and international financial weakness. Therefore, the Vienna crash is best described as an important trigger rather than the sole cause of the wider global downturn.
