The Berlin Stock Exchange, known by its MIC code XBER and officially called Börse Berlin, is one of Germany's oldest stock exchanges, founded on June 29, 1685 by an edict of Elector Friedrich Wilhelm of Brandenburg. It operates Monday through Friday from 8 a.m. to 8 p.m. Berlin time, making it one of the longest trading-window exchanges in Europe. All trades are conducted in euros, and it currently lists stocks from 82 nations, including major NASDAQ stocks and companies from China and South Africa.
Think of it as a secondary market with an unusually wide international reach for its size, trading stocks that primary exchanges in other countries handle first.
Before World War I, the Berlin Stock Exchange was the largest in Germany and comparable in size to the London Stock Exchange and the New York Stock Exchange. The exchange closed in 1914 at the outbreak of war and did not reopen until 1917 under strict government controls. On May 13, 1927, in an event known as "Black Friday," the Berlin index lost 31.9% of its value in a single day following Reichsbank President Hjalmar Schacht's attempts to limit financial speculation. Trading was suspended entirely in 1943 due to war-related economic pressures, and the exchange building was destroyed by an air raid in May 1944.
The post-war exchange rebuilt slowly. In September 2007, Börse Berlin acquired a majority stake in EASDAQ NV, which operates under the Equiduct brand. In October 2019, Tradegate Exchange GmbH acquired 100% of Börse Berlin AG, making Tradegate the current operator of the exchange.
The Berlin Stock Exchange operates two distinct trading systems. Xontro is the traditional system and handles floor-based trading and settlement for Berlin and other regional German exchanges. Equiduct, the electronic trading platform acquired through the 2007 EASDAQ deal, handles the exchange's electronic operations and future development. The combination gives the exchange flexibility across both traditional and algorithmic execution environments.
BaFin, Germany's Federal Financial Supervisory Authority, regulates the exchange. The Berlin Stock Exchange lists stocks, bonds, certificates, warrants, ETFs, and exchange-traded commodities. It holds a particular distinction for bond investors: it is the only exchange to list certain bonds issued by the German federation and its regional constituencies that are not listed on other exchanges.
International investors can trade on the exchange directly. The extended 8 a.m. to 8 p.m. trading window makes it possible to execute European securities outside the typical core session hours, which is especially valuable for after-hours positioning on German and international listings.
