Founded in 1931 and absorbed into KBC Group in March 2005, Almanij (short for Algemene Maatschappij voor Nijverheidskrediet, or "General Company for Industry") was a Belgian holding company engaged in financial services.

As a project of the Catholic Algemeene Bankvereeniging, a Belgian bank established by the Leuvense Volksbank (Leuven) in Antwerp in 1921, Almanij was launched in 1931. To reorganize its industrial interests in Hungary and Belgium, this was done. Due to the economic crisis of 1935, the Middenkredietkas came dangerously close to going out of business, which prompted the creation of the Kredietbank, in which Almanij became a stakeholder.

Instead of relying on the Middenkredietkas, which was intimately associated with the Algemeene Bankvereeniging, the Catholic Boerenbond (E: Belgian Farmers' Union) established its own network of savings banks: CERA. The Kredietbank Luxembourgeoise, a private banking institution, was established in Luxembourg in 1949.

Francine Swiggers took over for Rik Branson as Chairman of the Management Board of the ARCO Group.

The Belgian novelist and attorney Drieu Godefridi published an opinion piece in 2016 on the website of the journal Le Vif in which he argued that the Belgian State's 600 million euro payment to ARCO cooperators was crony capitalism. In fact, after the failure of the Belgian bank Dexia, of which ARCO was one of the major shareholders and which served as the financial arm of the Algemeen Christelijk Werknemersverbond (Christian Workers' Movement in Flanders), a political party affiliated with the CD&V, the Leterme government, whose Prime Minister was Yves Leterme, extended the bank guarantee of 100,000 euros to ARCO's 780,000 cooperators, most of whom were Flemish.
