Cryptocurrency Regulation in Switzerland: DeFi

Decentralised finance (DeFi) represents a fundamental transformation of the traditional financial landscape, offering financial services without intermediaries through blockchain technology. In Switzerland, this sector benefits from a progressive regulatory framework that continually adapts to technological innovations. The Swiss Confederation has positioned itself as a major hub for cryptocurrencies and DeFi, attracting many sector companies thanks to its legal stability and pragmatic approach.

Swiss Legal Framework Applicable to DeFi

The Swiss legal system approaches DeFi with a principle of technological neutrality. Rather than creating specific crypto-asset regimes, Switzerland applies its existing legal framework to DeFi activities, with targeted adaptations where necessary. For DeFi projects, the nature of the services offered may involve application of several Swiss financial laws:

• The Banking Act (BankA)
• The Financial Market Infrastructure Act (FinMIA)
• The Financial Services Act (FinSA)
• The Financial Institutions Act (FinIA)
• The Anti-Money Laundering Act (AMLA)

DeFi Legal Risks in Switzerland

Regulation of Specific DeFi Services

Decentralised Lending and Borrowing

Decentralised lending platforms allow users to lend or borrow crypto-assets without traditional intermediaries. In Switzerland, these activities may be subject to the Banking Act if they involve accepting public deposits. FINMA has clarified that truly decentralised platforms, where funds are exclusively managed by smart contracts without human intervention, may benefit from a differentiated regulatory approach.

Regulatory attention points for DeFi lending protocols:

• The actual degree of decentralisation in fund management
• The transparency of mechanisms for setting interest rates
• The protective measures against liquidity risks
• Anti-money laundering compliance for user interfaces

Decentralised Exchanges (DEX)

DEXs allow peer-to-peer exchange of crypto-assets without a central custodian. Under Swiss law, these platforms may be classified as multilateral trading facilities under FinMIA, potentially requiring FINMA authorisation. However, fully automated DEXs via smart contracts often benefit from lighter regulatory treatment.

The distinction between liquidity pool and order book models also influences the regulatory approach. User interfaces facilitating access to DEXs may be subject to financial intermediary obligations under AMLA, even if the underlying protocol is decentralised.

Taxation of DeFi Activities in Switzerland

Taxation of Staking and Yield Farming Income

Income generated by staking (participation in transaction validation) and yield farming (provision of liquidity) is generally considered taxable investment income for natural persons. For private investors, this income is subject to income tax at ordinary rates.

The precise tax classification depends on several factors:

• The nature of the DeFi protocol used
• The duration of commitment of funds
• The investor's level of activity
• The degree of automation of operations

Treatment of Capital Gains

In Switzerland, capital gains realised on private assets are generally exempt from tax. This rule applies to crypto-assets held as private investments. However, the boundary between private wealth management and ancillary business activity is sometimes thin in the DeFi context.

Tax authorities examine:

• The frequency of transactions
• The holding period of assets
• Use of borrowed capital
• Use of derivatives or sophisticated techniques

Declaration of DeFi Assets

Positions in DeFi protocols must be declared as part of the taxable wealth of Swiss taxpayers. Valuation is generally at market value on 31 December. For unlisted tokens or liquidity positions in pools, specific valuation methods may be necessary.

Regulatory Compliance Challenges for DeFi Projects

Identification of Parties and Anti-Money Laundering

The pseudonymous nature of blockchain transactions poses a major challenge for anti-money laundering compliance. While DeFi protocols themselves may operate without user identification, interfaces and access points to these protocols are often subject to AMLA obligations. Requirements include:

• Client identity verification (KYC)
• Identification of the beneficial owner
• Monitoring of suspicious transactions
• Reporting obligation in case of suspicion
