Swiss sanctions and contract law: How far do GTC compliance clauses reach?

Swiss sanctions and contract law: How far do GTC compliance clauses reach?

<p>In its decision 4A_455/2025 of 21 May 2026, the Swiss Supreme Court addressed the extent to which a commercial bank may rely on its general terms and conditions (GTCs) to refuse the release of client assets where performance could expose the bank to sanctions under Swiss or foreign law, and whether such a clause continues to apply after the notice of termination of the banking relationship.</p> <p>The Court held that under Swiss law provisions of a bank’s GTCs may include provisions conditioning performance by the bank to compliance with foreign legal and regulatory requirements and such compliance reservation clauses continue to apply post-termination during the liquidation phase of the account relationship. The judgment further clarifies that a Swiss governing law clause does not preclude the parties from agreeing, through acceptance of GTCs, that performance may be refused in order to comply with foreign legal and regulatory requirements. It also provides important guidance on the assessment of ownership and control for sanctions purposes.</p>

Swiss sanctions and crypto assets services: When can providers refuse instructions?

Swiss sanctions and crypto assets services: When can providers refuse…

<p>In two decisions of 28 April 2026 (4A_535/2025 and 4A_537/2025), the Swiss Federal Supreme Court addressed the application of Switzerland's sanctions asset freeze regime to crypto assets held with a Swiss provider of crypto asset brokerage and custody services. The Court confirmed that, where concrete indications give rise to the suspicion that crypto assets may be owned or directly or indirectly controlled by a sanctioned person, the service provider may validly refuse to execute client instructions to release or transfer those assets.</p> <p>The decisions clarify the interaction between the service provider’s public-law obligations under the Swiss sanctions framework and its contractual duties towards the client. They also raise practical questions specific to the custody of digital assets, in particular where access to the assets depends on wallets, private keys or custody infrastructure.</p>
