Banking for Crypto Companies in Zug: Sygnum, AMINA, and the Swiss Banking Landscape

For all of Zug’s advantages as a blockchain business jurisdiction — low taxes, fast company formation, a deep specialist ecosystem — the banking situation remains the most operationally painful reality for crypto companies establishing in Switzerland. Traditional Swiss banks, with their centuries of institutional conservatism and post-2008 AML compliance burdens, have largely decided that blockchain and crypto businesses are more trouble than they are worth. The good news: Switzerland’s regulatory framework created a solution that no other jurisdiction has matched — FINMA-licensed digital asset banks specifically designed to serve the companies that traditional banks refuse.

The Traditional Banking Problem

The Swiss banking system is exceptional in many respects: stable, confidential (within legal limits), technologically advanced, and deeply integrated into global payment infrastructure. For crypto companies, it is largely inaccessible.

UBS, Switzerland’s dominant universal bank and the surviving entity after the Credit Suisse collapse, applies rigorous AML/KYC standards that effectively exclude most crypto businesses from routine corporate banking. The compliance burden of onboarding a crypto company — understanding transaction flows, classifying digital assets, assessing DeFi exposure, evaluating smart contract risk — exceeds UBS’s appetite for businesses outside its institutional client coverage.

Swiss cantonal banks, including Zuger Kantonalbank (the Zug-headquartered cantonal bank), ZKB (Zürcher Kantonalbank), and Basellandschaftliche Kantonalbank, are generally more conservative than UBS in this regard, not less. Their retail-focused mandates and state-adjacent ownership structures make them particularly cautious about reputational risk from crypto association.

Raiffeisen and other cooperative banking structures have similarly limited appetite for crypto business accounts.

The consequence: a blockchain company incorporated in Zug in the morning can find itself without a functional business bank account weeks later. This is not a regulatory failure — FINMA has not instructed banks to refuse crypto clients — but an industry-wide commercial decision driven by compliance cost calculus.

The Solution: FINMA-Licensed Digital Asset Banks

Switzerland’s response to this structural gap was to license a new category of bank specifically equipped to serve the digital asset economy. Two institutions now hold full FINMA banking licences and are specifically positioned to provide corporate banking services to blockchain and crypto companies:

Sygnum Bank AG

Sygnum Bank AG, headquartered in Zurich and operating in Singapore and Abu Dhabi, holds a full Swiss banking licence from FINMA and a Capital Markets Services licence from the Monetary Authority of Singapore. It is co-founded by veterans of Swiss and international banking, consulting, and blockchain industries.

What Sygnum provides for Zug businesses:

• Multi-currency corporate accounts — CHF (Swiss franc, with Swiss IBAN), EUR, USD, SGD, and additional currencies based on business requirements
• SWIFT connectivity for international payment rails — critical for companies paying suppliers, employees, and counterparties globally
• Swiss IBAN — enables CHF payments through the Swiss domestic payments infrastructure (SIC system), required for cantonal tax payments, social insurance contributions, and domestic Swiss supplier payments
• Digital asset custody — regulated custody of Bitcoin, Ethereum, and other major digital assets, with institutional-grade security architecture (multi-signature wallets, HSM-secured infrastructure)
• Digital asset brokerage — execution of digital asset trades at institutional scale
• Tokenisation services — issuance of digital securities (DLT ledger-based securities under the Swiss DLT Act framework)
• Capital deposit accounts for company formation — critically, Sygnum provides the capital deposit accounts that traditional banks refuse for crypto company formations

Who Sygnum serves: blockchain technology startups, protocol foundations, digital asset trading companies, crypto hedge funds, family offices with digital asset exposure, and established fintech businesses requiring regulated Swiss banking infrastructure.

Account opening timeline: expect 4–8 weeks for the full KYC process from application to operational account. Sygnum’s onboarding is thorough: the team has deep knowledge of crypto business models and asks detailed questions about revenue sources, transaction flows, and counterparty profiles that traditional bank compliance teams often cannot even formulate.

AMINA Bank AG

AMINA Bank AG (formerly SEBA Bank AG, rebranded in 2023) is Sygnum’s principal peer in the FINMA-licensed digital asset banking space. AMINA holds a Swiss banking licence and a securities firm licence from FINMA, and operates additional licences in Abu Dhabi, Hong Kong, and other jurisdictions.

A distinguishing feature: Julius Baer, the established Swiss private bank, holds approximately 15% of AMINA Bank, providing a linkage to the traditional Swiss private banking establishment that adds institutional credibility for counterparties assessing AMINA’s regulatory standing.

What AMINA provides:

• Multi-currency accounts with particular strength in HKD (Hong Kong dollar) and AED (UAE dirham) — making AMINA particularly well-suited for companies with significant Asia-Pacific or Middle East business activity
• SWIFT connectivity and correspondent banking relationships
• Digital asset custody, brokerage, and staking services
• Structured products and lending against digital asset collateral
• Capital deposit accounts for Swiss company formations
• DLT-based securities services under the Swiss regulatory framework

AMINA’s Asia-Pacific orientation — through its Hong Kong and Abu Dhabi presences — makes it a strong choice for companies with significant business in those markets who want Swiss headquarters banking that connects to their operational geographies.

What to Expect When Opening an Account

Account opening at either Sygnum or AMINA is a serious compliance process, not a form-filling exercise. Both banks are FINMA-supervised and take their AML/KYC obligations seriously. The documentation and information required typically includes:

Corporate documentation:

• Commercial register extract (Handelsregisterauszug) — recent, certified copy
• Articles of association (Statuten) — certified copy
• List of directors and authorised signatories with identification documents

Beneficial ownership (UBO) documentation:

• Identification of all ultimate beneficial owners (typically persons owning 25%+ of the company, but banks may require disclosure of all significant shareholders)
• Copies of passports or national IDs
• Proof of residential address for all UBOs
• Source of wealth declaration for significant UBOs

Business documentation:

• Business plan — concise but substantive; explain the business model, revenue sources, client types, and expected transaction flows
• Source of funds declaration — particularly important for crypto companies: where is the capital coming from? If token proceeds, from which token sale? If investor capital, who are the investors?
• Website, whitepaper, or other public documentation of the project
• If a previous banking relationship existed: bank statements or reference letters

Blockchain-specific documentation:

• If the company has already conducted token sales: tokenomics documentation, jurisdictions of sale, buyer types, AML/KYC procedures applied to token buyers
• If the company holds or expects to hold digital assets: which assets, estimated volumes, custody arrangements
• Description of any DeFi protocol interactions

Timeline: expect 2–8 weeks from complete documentation submission to account opening decision. Incomplete documentation is the primary cause of delay. Some applications require additional information rounds; building in a 3-month timeline for account opening is prudent for planning purposes.

Costs: banking fees at Sygnum and AMINA are higher than traditional Swiss banks, reflecting the specialised nature of the service. Typical cost ranges:

• Monthly account maintenance fee: CHF 200–500+ depending on account tier and services
• Domestic CHF payment fees: CHF 0–5 per transaction at standard tiers
• International SWIFT payment fees: CHF 15–50 per transaction depending on currency and destination
• Digital asset custody fees: typically 0.25–0.75% per annum on assets under custody
• FX conversion fees: built into spread, typically 0.2–0.5% for major currency pairs

Traditional Bank Access: The Exceptions

The picture for traditional Swiss banking is not uniformly closed. A minority of cantonal and regional banks have moved toward greater openness for blockchain businesses that meet specific criteria:

Zuger Kantonalbank has been more engaged with the Crypto Valley ecosystem than most cantonal banks, partly due to its geographic positioning in Zug and the regulatory pressure from the cantonal government’s pro-blockchain stance. Companies with FINMA authorisation or clear SRO membership, operating genuine Swiss businesses with local employees and local business activities, have had more success at Zuger Kantonalbank than at national universal banks.

Schaffhauser Kantonalbank has developed a degree of expertise in blockchain and digital asset businesses, in part because some early Crypto Valley companies established relationships there when alternatives were more limited.

The key variables that improve traditional bank access: FINMA authorisation or SRO membership (demonstrating external regulatory supervision beyond FINMA banking licensing); clear Swiss operational substance (employees in Switzerland, local business activities, not a brass plate entity); a simple and clearly compliant business model (software development is easier than digital asset trading); and founders with existing Swiss banking relationships.

International Banking: Lessons from US Crypto Banking Failures

Until 2023, several US banks provided an alternative banking layer for crypto companies: Silvergate Bank and Signature Bank both operated crypto-specialist banking services, with Silvergate’s Silvergate Exchange Network (SEN) and Signature’s Signet providing near-real-time USD payment rails between crypto companies.

Both banks collapsed in March 2023, in the broader turmoil following the FTX collapse. Silvergate entered voluntary liquidation; Signature was seized by New York state regulators. Their collapse eliminated the two primary US crypto-specialist banking providers and concentrated demand on surviving regulated alternatives — including Sygnum and AMINA in Switzerland.

The lesson: institutional-quality crypto banking requires regulatory substance, not regulatory arbitrage. Sygnum and AMINA hold full Swiss banking licences — the same regulatory weight as UBS or any other Swiss bank — with FINMA supervision. This is the correct model for companies requiring enduring banking infrastructure.

Capital Deposit Accounts: The Formation Bottleneck

One specific banking service deserves explicit attention: the capital deposit account required for company formation (see the separate article on incorporating in Zug). Traditional banks routinely refuse these for crypto company formations, creating a circular problem: you cannot form the company without a capital deposit account, and you cannot open a capital deposit account at a traditional bank because you are a crypto company.

Sygnum and AMINA both provide capital deposit accounts specifically for this purpose. The documentation requirements are similar to a full account opening — expect to submit business plan, founder identification, and source of funds information even for a formation-stage capital deposit account.

Practical advice: start the capital deposit account opening process at Sygnum or AMINA before you finalise your notary appointment. If the bank process encounters delays — additional information requests, UBO verification queues — you do not want your notary availability to be the constraint. Both banks and notaries can then be coordinated once both processes are close to completion.

Practical Strategy: Banking Setup for a New Zug Company

For a newly forming Zug blockchain company, the recommended banking approach:

1. Apply to Sygnum and AMINA simultaneously. The applications are independent; having parallel processes running protects against delay at either institution and gives you leverage in negotiations on fees and service terms.

2. Prepare a complete KYC package before applying. Assembling founder identification, source of funds documentation, and a clear business plan before starting applications dramatically reduces delay from information requests.

3. Engage a compliance counsel for complex structures. If your company has multiple UBOs, offshore investors, existing token holdings, or a DeFi protocol interaction layer, an experienced Swiss compliance lawyer can prepare the KYC package in a form that directly addresses the questions banks will ask.

4. Budget 3 months for account opening. Even with a clean application and cooperative bank, this is a realistic minimum for operational account setup. Plan company cash flow and initial operating costs accordingly.

5. Do not rely on a single banking relationship. Once established at Sygnum or AMINA, explore whether a traditional cantonal bank relationship is attainable as a complementary account. Diversification of banking relationships is prudent risk management.

Switzerland’s digital asset banking infrastructure is the most developed of any major financial jurisdiction. The combination of FINMA-licensed digital asset banks, clear regulatory frameworks, and Swiss payment system connectivity gives Zug-based blockchain companies banking infrastructure that their counterparts in Berlin, London, or Singapore cannot easily replicate.

For companies at the company formation stage, the choice between AG and GmbH structures determines the capital deposit amount and share transfer mechanics — both relevant to how the banking relationship is structured from inception. The full Zug incorporation process covers how the capital deposit account fits into the formation timeline and why it must be established before the notarial founding act.
