Which Swiss exchange was formed in 1993 by merging the exchanges of Zurich, Basel, and Geneva?

SIX Swiss Exchange was formed in 1993 by merging the exchanges of Zurich, Basel, and Geneva.

The merger created a unified Swiss securities market from three regional exchanges. It helped modernize and centralize trading in Switzerland, where different cities had previously maintained their own organized markets.

The exchange was originally known as the Swiss Exchange, or SWX, before the organization adopted the SIX name. SIX Swiss Exchange is headquartered in Zurich and lists Swiss and international securities, including shares, bonds, exchange-traded products, and other instruments.

The exchange is frequently confused with SIX Group, the parent organization that operates financial-market infrastructure and payment systems. SIX Swiss Exchange is the trading venue, while SIX Group is the broader company. The Swiss Market Index is the best-known benchmark associated with the Swiss equity market, but it is an index rather than the exchange itself.
