What Happens When Crypto Becomes A Feature Inside Your Bank?
Swiss banks now let customers buy crypto through ordinary banking apps, hold it in custody accounts, include it in managed portfolios and, in some cases, borrow against it. Germany is moving in the same direction. The change is less about another place to buy Bitcoin than about bringing digital assets into ordinary banking infrastructure.
A Swiss banking customer no longer necessarily needs a crypto exchange to buy Bitcoin. Zürcher Kantonalbank lets customers trade Bitcoin, Ethereum, Solana and Chainlink through eBanking or its mobile app. The bank records the assets in the customer’s existing securities custody account and manages the credentials needed to access them. Crypto therefore appears beside conventional investments rather than in a separate wallet or platform. PostFinance has gone further. By February 2026, its customers could trade 22 cryptocurrencies directly from a private or savings account. They had opened more than 36’000 crypto portfolios and completed more than 565’000 trades since the service launched.
For a customer, this is a very practical practical move because instead of opening an account with a crypto exchange, transferring money there and arranging separate custody, the customer can stay inside an existing banking relationship. The bank handles custody and places the position inside the portfolio view. However, customers who use bank custody no longer control the private keys themselves. Some will regard that as a disadvantage because direct ownership sits at the heart of the original crypto model. Others will prefer not to carry the technical responsibility of safeguarding credentials that can determine access to the asset.
ZKB currently operates its service on an execution-only basis and does not allow customers to transfer the cryptocurrencies into or out of the bank. That distinction matters. Two banks may both advertise crypto trading while offering customers very different levels of control over the underlying assets.
Crypto Is Moving Into Wealth Management
PostFinance moved crypto beyond simple execution in February 2026 when it added selected cryptocurrencies to an asset-management mandate. Its Future mandate allocates 80 percent to globally oriented investments, 15 percent to megatrends and 5 percent to selected cryptocurrencies.
The bank now treats those holdings as part of a managed portfolio rather than a separate speculative account. It sets the allocation and manages the crypto exposure alongside conventional assets.
Luzerner Kantonalbank has followed another path. After integrating crypto trading into its core banking, e-banking and mobile systems, it added lending. Since September 2025, eligible customers have been able to pledge Bitcoin and Ethereum as collateral for Lombard loans. A client can therefore raise cash without selling the crypto position first. The bank has to decide how much credit it will advance against an asset whose price can fall sharply, monitor the collateral and respond if its value drops below the required level. LUKB uses conservative lending values to account for that volatility. That changes the role of crypto inside the bank because Bitcoin no longer sits only in a trading account. It can enter portfolio management, collateral calculations and credit decisions.
Germany Shows What Happens When The Model Reaches Mass Banking
Germany is at an earlier stage, but its banking market brings much greater retail scale. Volksbanken and Raiffeisenbanken serve around 30 million customers, while Sparkassen serve roughly 50 million. As those institutions add crypto access, they can place digital assets in front of customers who might never have opened an account with a specialist exchange.
Demand remains uneven. Only a minority of Germans have bought cryptocurrencies, but surveys show a much larger group considering them. Research has also found that German investors trust their main bank for crypto trading more than specialist platforms.
That gives established banks an advantage that goes beyond technology. They already hold the customer relationship, know the account holder and have completed the identity checks required to provide financial services. They do not need to build every part of the crypto operation themselves either. Börse Stuttgart provides trading and custody infrastructure for participating Volksbanken and Raiffeisenbanken. Individual banks still need governance, regulatory approval and customer controls, but they can connect to specialist infrastructure rather than create an exchange and custody operation from scratch.
ZKB uses a similar model in Switzerland. It has made its crypto infrastructure available to third-party banks as well as its own customers.
For smaller banks, the attraction is simple: they do not need to build the full crypto operation themselves. They can keep the customer relationship and regulatory responsibility while using specialist providers for trading and custody.
Banks also need to be careful about how they present the service. A Bitcoin button inside a familiar banking app can easily look like an endorsement, even when the bank only provides execution and custody. The communication should therefore make clear what the bank is actually offering: whether it recommends the asset or simply gives access to it, who executes the trade, who holds the crypto, who controls the private keys and whether customers can move the asset to an external wallet.
PR teams also need to be precise when they talk about security. Bank custody can remove the risk of a customer losing their own private keys. It does not remove Bitcoin’s price volatility, cyber risk or the operational risks associated with a third-party custodian.
Calling the product “safe” therefore says too little. A bank should say which risk it is reducing and which risks remain.

The communication becomes more demanding when crypto enters wealth management. A client considering a managed portfolio needs to know why the bank has chosen a particular allocation and how it controls the exposure. Someone borrowing against Bitcoin needs to understand the collateral value the bank applies and what happens if the price falls.
Those points should appear in the customer proposition, not only in legal documents.
How To Communicate A Bank Crypto Offer
Access
Say which assets customers can buy, how they fund the transaction and whether minimum purchase amounts apply.
Custody
Explain who holds the assets and who controls the private keys. State whether customers can transfer crypto to an external wallet.
Risk
Separate custody security from investment risk. Bank custody does not make Bitcoin less volatile.
Advice
Make clear whether the bank recommends crypto or simply provides execution and custody.
Third Parties
Explain what external trading or custody providers do when they sit behind the service.
Portfolio Treatment
State whether crypto remains a standalone holding or can enter a managed mandate, collateral calculation or wider wealth report.
The communications test: a customer should understand not only that the bank offers crypto, but who does what after they press Buy.
Custody Moves Responsibility Into The Bank
Removing a private wallet from the customer journey does not remove the custody problem. FINMA warned Swiss institutions in January 2026 that crypto custody requires technical expertise and robust infrastructure. The regulator also raised the risk that assets held with an external custodian, especially one in another jurisdiction, could become difficult to recover if that provider fails.
Swiss banks remain responsible when they outsource the work. An external custodian may hold the keys, but the regulated institution still has to assess the provider, structure the custody arrangement properly and protect its customers.
Bank custody therefore changes where the operational risk sits. A self-custody customer has to protect their own credentials. A bank customer depends on the institution’s technology, internal controls, contracts and external providers.
German banks entering crypto under the EU’s MiCA framework need the relevant regulatory authorisation, and the approval process can take months even when a banking group provides a standardised route. The technical product may look like another button in an app but the operating model behind it does not.
Switzerland Is Testing What Comes After Trading
Swiss institutions are already looking beyond crypto as an investment product. In September 2026, nine organisations (Raiffeisen, UBS, PostFinance, Sygnum, Zürcher Kantonalbank, BCV, SIX, TWINT and Swiss Stablecoin AG) began testing applications for a Swiss-franc stablecoin in a controlled live environment.
A franc-backed stablecoin serves a different purpose from Bitcoin held for investment. It raises questions about payments, settlement and how blockchain-based money interacts with existing financial infrastructure. SIX brings financial-market infrastructure to the project, while TWINT brings experience in everyday digital payments.
Swiss banking now offers several examples of how far digital assets can move into ordinary finance. Customers can trade them through bank apps, hold them in custody accounts, include them in managed portfolios and use some of them as collateral for loans. Banks are also testing how tokenised money could enter payments and settlement.
For customers, the service looks simpler because the bank handles more of the infrastructure. For banks, offering crypto means taking responsibility for custody, compliance, reporting, lending and risk controls.
The next stage is not simply adding more coins. It is deciding how far digital assets should be integrated into the rest of the banking relationship.
