The general Commodity Exchange founded in 1872 was joined with the Vienna Stock Exchange to form the Vienna Stock and Commodity Exchange in 1876. Ever since, the Wiener Börse has had two departments; the Stock Exchange and the Commodity Exchange. However, Vienna had never been an important market for commodities. High volumes of dealings in commodities were made only during the years 1921 to 1924. The importance of the Vienna Commodity Exchange for the economy today lies above all in such typical ancillary activities as drawing up trading rules, expert opinions and sample drawings, and in the Court of Arbitration.

The Commodity Exchange gained new significance when trading in electric power was introduced on 21 March 2002 and trading in gas contracts on 11 December 2009.
