Cash Group is a cooperation of the four largest German private banks (Deutsche Bank, Commerzbank, HypoVereinsbank, and Postbank) and their subsidiaries, in which they mutually waive ATM usage fees for their customers.

However, this agreement was terminated by the Sparkassen (public banks), who jointly operate the largest German ATM network, arguing that the cost of operating ATMs was unfairly laid on them when virtual banks entered the market.

Therefore, in 2000, several smaller German banks founded CashPool as an answer to Cash Group.

It left CashPool and became a member of Cash Group after its acquisition by Deutsche Bank in 2006.
