Sparkassen Network Launches Cryptocurrency Trading App for Bitcoin and Others
Germany's largest savings bank network, Sparkassen, has launched trading services for Bitcoin, Ethereum, XRP, Solana, and Polygon within existing bank apps starting October 19, provided by its subsidiary DekaBank under the product name Krypto powered by Deka. Customers can open independent crypto accounts through the app's investment section to buy and sell without needing a separate securities account. Custody is led by DekaBank, which collaborates with Börse Stuttgart to handle trading infrastructure, and customers do not hold private keys.
Currently, about five institutions are participating, including Frankfurter Sparkasse, Taunus Sparkasse, Sparkasse Karlsruhe, Sparkasse Rottal-Inn, and Niederrheinische Sparkasse RheinLippe. There is no unified nationwide launch date; each Sparkasse decides its own start time.
Joachim Schmalzl, a member of the DSGV executive board, stated that 30 to 40 new institutions are expected to join each month, with over 230 (about two-thirds of the total approximately 337) expressing interest. The goal is to complete the onboarding of most interested institutions by the first half of 2027.
A fixed fee of €0.99 is charged per transaction, plus the buy-sell spread, with some actual trading reports indicating that the Bitcoin purchase price is about 1.34% higher than the market reference price. Withdrawals are limited to specific approved crypto service provider addresses, and direct transfers to personal hardware wallets are not allowed. The bank does not provide investment advice and does not plan to promote this widely, clearly warning of the risks of price volatility and potential total loss.
Retail customer funds are shifting from traditional exchanges and non-bank channels to custodial accounts within bank apps, with DekaBank holding assets and collecting spreads and fees. Driven by events, the banking system connects existing customer deposits with crypto demand, benefiting DekaBank and Börse Stuttgart from increased trading volume and custody scale, while independent crypto exchanges and self-custody tools face customer diversion pressure.

The Sparkassen group has long characterized cryptocurrencies as highly speculative assets and explicitly advised institutions against providing related services around 2022, with some historical decisions even restricting customers from direct purchases. In 2025, due to rising customer demand and the implementation of the EU MiCA framework, the group shifted to developing proprietary products through DekaBank, completing a policy reversal from refusal to phased onboarding.
The funding pathway is centralized within the group: customers open DekaBank crypto accounts in the existing app, with assets held by DekaBank and quotes and liquidity provided in collaboration with Börse Stuttgart, keeping transaction fees and spreads within the banking system. This move redirects retail funds that would have gone to external exchanges back into the group's securities and custody platform while avoiding the compliance and operational risks associated with self-custody.
This pathway is similar to the meinKrypto launched by the German cooperative banking system through DZ Bank, both opting to embed limited cryptocurrency trading within existing bank apps rather than building a complete exchange. Currently, Sparkassen is in the early stages of expansion, having completed technical and regulatory preparations, and is expanding coverage at a rate of 30-40 institutions per month, aiming to onboard most interested institutions by the first half of 2027, integrating crypto trading into traditional retail banking channels.
Essentially, this represents capital concentration and industrial chain restructuring. By centralizing custody and using a fixed fee model, banks consolidate dispersed retail crypto demand into regulated entities, reducing operational and compliance risks associated with self-custody while keeping trading and spread revenues within the group. The regulatory clarity provided by MiCA lowers the entry barrier, allowing the previously conservative savings bank network to absorb crypto demand in a controlled manner rather than completely ceding customers to non-bank platforms.
