The PSD Bankengruppe is a German cooperative banking group consisting of 14 autonomous and independent financial institutions.

The Post-Spar- und Darlehnsverein banks originally provided financial services by postal clerks only and were assigned to the areas by the post office.

[4] In the context of the German reunification the PSpDV associations which were located close to the new federal states of Germany expanded their business areas.

Also, up to that point only clerks and employees of the former Deutsche Bundespost (German Federal Post Office) as well as their relatives were accepted as customers and members of the banks.

Except the PSpDV Hannover all associations introduced the universal bank business (check accounts, stock broking etc.)

Today Fiducia & GAD IT AG is the data center and IT service provider of the 14 PSD banks in Germany; prior it was the datacenter of the Sparda-Banks in Nuremberg.

In August 2009 the PSD banks formed a collaboration with financial service provider Hypoport for process optimization and the development of collective products.
