Dexia N.V./S.A., also referred to as the Dexia Group, is a Franco-Belgian financial institution active in public finance, providing retail and commercial banking services to individuals and SMEs, asset management, and insurance. The company has about 35,200 members of staff and core shareholders' equity of €19.2 billion as at 31 December 2010, and provides governments and local public finance operators with banking and other financial services. Asset Management and Services provides asset management, investor and insurance services, in particular to clients of the two other business lines. In 2008, the bank received bailouts for €6 billion, and it has become the first casualty of the 2011 European sovereign debt crisis. Negotiations are taking place for its breakup.

In the 2010 Fortune Global 500 (which lists companies by total income) Dexia was ranked 49th, the top-ranked Belgian company.

The company was founded in 1996 through the merger of Crédit Communal de Belgique/Gemeentekrediet van België (founded in 1860) and Crédit Local de France (founded in 1987). The Dexia Group was founded as a dual-listed company, but in 1999 the Belgian entity took over the French entity to form one company. The company is headquartered in Brussels, Belgium.
