Crypto-Asset Banking in Switzerland: Regulated Custody, the DLT Act, and What Onboarding Looks Like

Last reviewed on 25 April 2026.

Switzerland is one of the few jurisdictions where digital-asset banking sits inside a fully supervised banking framework rather than alongside it. That has practical consequences. A Swiss-licensed crypto bank can hold Bitcoin or Ether for an institutional client under the same prudential and resolution regime that governs deposit-taking; tokenised securities can be issued and traded as legally recognised "register securities" under the DLT Act; and the supervisory authority (FINMA) has been classifying tokens by economic function — payment, utility, asset, stablecoin — for long enough that compliance teams know what they are looking at.

This page steps back from individual brand profiles in the digital banks section and explains the regulatory architecture, what each licence category actually allows, how onboarding differs from a traditional Swiss private bank, and the realistic constraints for non-resident clients.

The legal framework: more than one Act

Three pieces of Swiss law together do most of the work for crypto-asset banking:

• The Banking Act sets the rules for banks generally — capital, liquidity, depositor protection, FINMA supervision. Swiss "crypto banks" with a full banking licence operate inside this Act, with the same Basel III "Swiss Finish" capital requirements that apply to any other bank.
• The Financial Market Infrastructure Act (FinMIA), as amended by the so-called DLT Act, introduces a specific category of distributed-ledger trading facility (DLT trading venue) and recognises register securities — securities whose ownership is recorded directly on a distributed ledger and whose transfer follows the rules of that ledger.
• The Anti-Money Laundering Act (AMLA) applies in full to digital-asset services. Travel-rule equivalent obligations have been adapted to address self-hosted wallet transactions, with stricter information requirements than apply in many other jurisdictions.

Layered on top is FINMA guidance — most importantly the ICO/token classification framework, which sorts tokens into payment tokens, utility tokens, asset tokens, and hybrid forms, and sets out the licensing implications of each.

FINMA's licensing categories

Three licensing categories are most relevant for crypto-asset activity in Switzerland:

1. The full banking licence

A full banking licence allows the holder to take public deposits, make loans, and provide the broad range of banking services. Several Swiss institutions with this licence focus specifically on digital assets — combining cryptocurrency custody, trading, and lending with traditional CHF and foreign-currency banking. From a depositor's perspective, the deposits at a fully licensed crypto bank are subject to the same protection regime described in Swiss deposit protection, while the cryptocurrency holdings are segregated assets in custody (and so not part of the deposit-protection perimeter, but ring-fenced in insolvency under custody rules).

2. The fintech licence (Banking Act, art. 1b)

The "fintech licence" — sometimes called the "banking licence light" — allows the holder to accept public deposits up to CHF 100 million, with restrictions: no interest-bearing deposits, no investment of those deposits for the firm's own account, and lighter capital requirements than a full bank. It exists specifically to give early-stage Swiss fintechs a regulated runway without the cost of full banking compliance. Several digital-banking offerings are built on this licence; it is a real licence with real obligations, not a token authorisation.

3. The DLT trading-venue licence

The DLT trading-venue category allows multilateral trading of register securities — including by retail participants in some configurations — within a single licensed entity that combines what would otherwise be separate exchange and post-trade infrastructures. This is the rail on which tokenised bonds, tokenised funds, and similar instruments are intended to live. From a client's perspective, it matters most when they want to hold tokenised securities as part of a broader Swiss custody relationship.

What a Swiss-licensed crypto bank actually offers

The product range of a typical Swiss-licensed crypto bank looks broadly like this:

• Custody. Segregated cold storage for major cryptocurrencies, with the legal status of a custody asset under Swiss law. In insolvency, custody assets are returned to the client rather than entering the bank's estate.
• Trading. Execution against the bank's liquidity (or against a panel of external venues), 24/7 in major pairs, with settlement directly into the same custody arrangement.
• Lombard lending. Borrowing against a portfolio that includes both fiat and digital assets, with conservative loan-to-value ratios and margin-call mechanics. The use of digital-asset collateral is one of the clearer differentiators.
• Staking. Yield generation by participating in proof-of-stake networks. Tax treatment of staking rewards in the client's home country is the responsibility of the client; the bank provides the data.
• Tokenisation services. Issuance and lifecycle management of register securities on selected DLT infrastructures, both as primary issuer-side service and as custody for clients holding tokenised positions.
• Banking and payments rails. CHF and major-currency accounts, SEPA and SWIFT, payment cards in some cases — the same operational infrastructure that any Swiss bank provides, used here to bridge between fiat and crypto.

Onboarding: how it differs from a traditional Swiss private bank

The general rules of account opening at a Swiss bank apply: identity verification, residence, source of wealth, source of funds, tax compliance, in-person or video-identification meeting where required. Crypto-asset banks add specific layers on top.

Source of wealth — for the digital-asset portion

Documenting fiat wealth is well-understood: pay slips, tax returns, brokerage statements, business sale documents. Documenting digital-asset wealth is harder because the natural audit trail (exchange statements, on-chain history) is often incomplete and lives across multiple platforms. Swiss crypto banks typically expect:

• A complete history of fiat-to-crypto purchases with bank statements and exchange records.
• Trading history per exchange, plus a reconciliation between recorded trades and current holdings.
• For larger or older holdings, a blockchain-analytics report from a recognised provider, mapping the relevant addresses to identified counterparties and flagging any high-risk interactions.
• Tax filings reflecting any taxable events that have already occurred — sales, swaps, staking income, airdrops, NFT proceeds.

Self-hosted wallets and the travel rule

Swiss travel-rule rules go further than some peers in requiring identification of the counterparty for transfers to and from self-hosted (non-custodial) wallets above defined thresholds. In practice, this means:

• To deposit from a self-hosted wallet you control, you may be asked to prove control (a small signed message or a micro-transaction) and to declare ownership formally.
• To withdraw to a self-hosted wallet, the bank may require similar evidence and may set per-period limits.
• Transfers to or from third-party self-hosted wallets — paying a counterparty directly, for example — are subject to higher scrutiny and may require contractual or commercial documentation.

Risk classification of activity

Banks classify the relationship's risk profile and the activity within it. DeFi yield strategies, cross-chain bridging, NFT marketplaces with weak KYC, and any interaction with sanctioned addresses raise the risk score. Some banks support some of those activities with extra documentation; others simply won't service them. Asking up front, with a written list of intended activities, is more efficient than discovering restrictions after onboarding.

Tax: what Switzerland does, and what your home country does

Swiss federal tax treatment of cryptocurrencies is reasonably stable: holdings are part of taxable wealth at year-end value (where a Swiss resident is concerned), trading gains by private individuals are typically tax-free as long as the activity stays within "private wealth management" criteria, and staking rewards or mining income are taxable as income. Cantonal practice varies on the boundary between "private investor" and "professional trader", with consequences that matter at scale.

For non-residents, none of this directly produces a Swiss tax bill on the digital-asset position — but the bank will still report under CRS / FATCA where applicable. The relevant tax system is your own. The same point made on the lump-sum taxation page applies here: Swiss banking does not change your home country's claim on your worldwide income or wealth; it only changes how Switzerland computes its share when you become Swiss tax-resident.

Worked example: an institutional onboarding

Imagine a single-family office in a non-EU jurisdiction wanting to add a Swiss crypto-banking relationship for a portfolio of around CHF 30 million in digital assets, alongside an existing CHF 200 million traditional portfolio at a separate Swiss private bank. The onboarding flow at a Swiss-licensed crypto bank would typically include:

• Initial scoping call to confirm acceptance of the family office structure, the principals' jurisdictions, and the planned activities (custody, trading, lending — but no DeFi or NFT activity, in this example).
• KYC documentation for the family office entity, the underlying principal(s), and any directors or signatories. The standard Swiss source-of-wealth narrative described in the documentation guide applies, with a separate section on the digital-asset history.
• Blockchain-analytics report covering the addresses from which the digital assets will be transferred in.
• Tax-compliance evidence — typically a letter from the family office's tax adviser confirming the position taken in the relevant jurisdiction and that any past taxable events have been properly reflected.
• Operational set-up: account opening, hardware-token onboarding, pre-approved withdrawal address whitelist, signing-policy configuration for the institution's internal controls.
• A first transfer of assets in stages, typically starting with a small test transfer for each asset, then the bulk move.

From first scoping call to fully operational account, this kind of onboarding usually runs over several weeks rather than days. The diligence is comparable to a traditional Swiss private-banking onboarding for the same wealth band, with extra digital-asset-specific layers on top.

What a Swiss crypto bank is not

It is worth being explicit about the limits.

• It is not a way to launder anything. The opposite, in fact: Swiss-licensed crypto banks are some of the most heavily monitored entry points between fiat and crypto, precisely because they sit inside the AMLA perimeter.
• It is not a substitute for trading-venue execution for active traders. Spreads at a custodian-bank are wider than at a top-tier exchange. The proposition is custody and integration, not execution alpha.
• It is not a way to access higher-risk DeFi yields. Most regulated banks restrict the yield strategies they will custody. Clients who want the full DeFi surface area will need a separate, lighter-regulated arrangement and accept the trade-off.
• It is not a substitute for tax compliance. The bank reports under standard exchange-of-information regimes; it does not file your tax return.

Common mistakes

• Assuming all "crypto-friendly" providers are equivalent. A FINMA-supervised bank, a fintech-licensed deposit-taker, and an unlicensed offshore platform are three different propositions with three different risk profiles.
• Underestimating onboarding documentation. Source-of-wealth for a multi-year crypto trading history is harder to assemble than for a corporate sale or an inheritance. Start collecting before you start applying.
• Treating self-hosted wallets as outside the perimeter. Transfers to and from self-hosted wallets are subject to the bank's policy, even if technically the wallet is "yours".
• Confusing "custody" with "deposit". Custody assets are ring-fenced; deposits are inside the deposit-protection regime. Different rules apply in insolvency.

Decision criteria when shortlisting

• Which licence does the institution actually hold — full banking, fintech, or something else? See the FINMA register for a definitive answer.
• Which assets does it custody, on which custody architecture (cold storage, MPC, hardware HSMs), and how is segregation evidenced?
• Which activities does it support — and explicitly does not support — for your jurisdiction?
• What does the fee schedule look like compared with a pure exchange, and what does it look like compared with a traditional Swiss private bank?
• Is the relationship complementary to an existing traditional Swiss banking relationship, or does the same provider also offer the fiat side at acceptable terms?

Done well, a Swiss crypto-banking relationship gives an institutional or HNW client the regulated counterpart they need on the digital-asset side of their balance sheet, sitting alongside the traditional banking relationship described in the main directory. Done casually, it is just an expensive exchange. The difference is almost entirely in the onboarding work — the part that happens before the first transfer arrives.
