The provision of certain information about a structured product is not sufficient to establish an investment advisory relationship, particularly if the client has in-depth knowledge and experience in the field of investment. In the absence of an advisory relationship, the choice of the issuer of the structured product within the group does not give rise to a conflict of interest (TF 4A_503/2025 of 17 June 2026). At the end of 2005, a company opened a custody account with the Geneva[...]

When drafted in broad terms, a compliance clause also covers foreign regulations and sanctions, even when Swiss law has been chosen as the governing law. The bank may rely on such a clause to freeze the relevant assets on the grounds that it must comply with foreign sanctions, even after the termination of the banking relationship (Federal Supreme Court 4A_455/2025 of May 21, 2026). In the case at hand, the client company holds cash accounts with a Swiss bank, a[...]

In its decision 4A_433/2025 of May 27, 2026, the Federal Court dismissed the appeal of a liability insurer that had refused to pay benefits under a policy structured according to the loss-occurrence principle. This mechanism links the claim to the time when the damage becomes apparent, rather than to the date of the underlying event. The insured, a manufacturer of aluminum composite panels used for facade cladding, had been covered by the appellant’s liability insurance for several years. The insurance[...]

In a ruling 4A_535/2025 dated April 28, 2026, scheduled for publication, the Federal Court rules on the right—or rather, the obligation— of an agent to refuse to carry out a client’s instructions when there is reason to believe that the client’s assets fall under the “freezing of assets and economic resources” provision within the meaning ofArticle 15 of the Ordinance Establishing Measures in Connection with the Situation in Ukraine (“Ukraine Ordinance”). On November 18, 2021, an investment company (the “Company”),[...]

According to Judgment 2C_506/2024 of May 4, 2026 (scheduled for publication), issued by the Second Public Law Division of the Federal Supreme Court, professional secrecy does not preclude Switzerland from providing a foreign state, in the context of administrative assistance proceedings, with documents held by the cantonal tax administration that it received from an attorney acting on behalf of his client. In this case, the Spanish tax authorities suspect a taxpayer domiciled in Switzerland of actually being domiciled in Spain.[...]

Can a foreign judgment be recognized in Switzerland if the defendant was never actually aware of the proceedings brought against him? This question arises in particular when the court, unable to serve the person, resorts to service by publication. In its decision 4A_157/2025 of March 13, 2026, the Federal Supreme Court clarifies that service is compatible with Art. 27(2)(a) of the Swiss International Private Law Act (LDIP) only if it offers the defendant a genuine opportunity to participate in the[...]

In an investment advisory relationship, if the client carries out transactions that do not result from advice given by the bank, the bank is not in a position of conflict of interest and may retain the retrocessions received (ACJC/439/2026 of 10 March 2026, which has entered into force). In 2015, an experienced and wealthy British client opened an investment advisory relationship with a bank domiciled in Geneva. According to the contractual documentation, the client had direct access to the trading[...]

Convictions for failure to exercise due diligence in financial transactions under Art. 305ter of the Swiss Criminal Code are rare; Federal Supreme Court rulings on the matter are even rarer. The landmark decision of April 13, 2026, addresses two points: 1) the scope of administrative and private anti-money laundering standards in determining the level of due diligence required by the circumstances when identifying the beneficial owner; 2) the question of whether the incorrect identification of the beneficial owner is an[...]

Under what conditions is a bank liable for the failure to execute a stock market order, and to what extent is a client responsible for their own communications and their silence? In a judgment of 20 January 2026, the Geneva Court of Justice clarified these issues by distinguishing between three scenarios: a clear order not executed without sufficient justification; an ambiguous communication not constituting a genuine instruction to sell; and the absence of a timely objection leading to the application[...]

Beyond the ongoing standoff between UBS and the Federal Council, particularly regarding the tightening of capital requirements, UBS’s takeover of Credit Suisse has also had implications under criminal law. In an order dated 8 April 2026 (SK.2025.57), the Criminal Division of the Federal Criminal Court examined the consequences, in terms of corporate criminal liability, of a merger by absorption (Art. 3 para. 1 let. a FusG) on the acquiring company. It ordered the proceedings against UBS to be discontinued, finding[...]

In a judgment intended for publication, the Federal Supreme Court has settled a previously unresolved issue by confirming that PostFinance may refuse to open a bank account on the grounds that the relationship would entail disproportionately high costs. This ground, provided for in Art. 45(1)(a) OPO, has a sufficient legal basis. In the present case, however, PostFinance was unable to demonstrate the existence of such costs (4A_454/2025 of 3 March 2026). In 2022, a Russian national resident in Switzerland applied[...]

In its final judgment ACJC/151/2026 of January 27, 2026, the Court of Justice of the Canton of Geneva upheld the dismissal of a claim for payment filed by a client who held the status of a qualified investor within the meaning of the aLPCC against a bank, following losses incurred on equity investments. It clarifies the scope of the bank’s duty of care in the presence of a qualified investor and excludes the application of exceptional circumstances, such as the[...]

When a creditor seeks to have assets located in Switzerland that belong to a foreign state placed under sequestration under the Swiss Debt Enforcement and Bankruptcy Act (DEBA), the creditor must, in particular, demonstrate that its claim has a sufficient connection to Swiss territory. In its decision 5A_617/2025 of January 29, 2026, the Federal Supreme Court confirmed that this requirement applies even when (i) the creditor is itself a foreign state, (ii) it relies on a final release order (Art.[...]

In the decision 5A_988/2025 of March 3, 2026, which is scheduled for publication, the Federal Supreme Court (FSC) ruled that the former officers of a company whose powers of representation have been revoked by FINMA retain standing to appeal the bankruptcy ruling on behalf of the company, even when the bankruptcy is declared by an ordinary court and not by FINMA itself. This extension of existing case law ensures effective access to justice (Art. 29a Cst.) in the context of[...]

The ten-year statute of limitations for a claim arising from an overdraft begins to run each time the balance is settled and acknowledged by the parties. However, when the contractual relationship continues, the balance is de facto carried over to a new account, such that these successive settlements give rise to new statutes of limitations. Termination of the contract, on the other hand, results in a final account statement, makes the balance due and payable, and triggers a new (and[...]

Whilst we have repeatedly highlighted the lack of detail in the summaries of the Banking Supervision Commission’s (hereinafter: the Commission) ‘leading cases’, it must be acknowledged that the latest publication raises a number of interesting and rarely addressed issues. Among these, we note first and foremost a clarification regarding the scope of application of the Bank Due Diligence Convention (hereinafter: the BDC or the Convention) in relation to credit card transactions. Recalling first of all that the CDB 20 applies[...]

In a ruling RR.2023.127-133 dated January 20, 2026, the Federal Criminal Court (FCC) dismissed appeals against a decision to return seized funds to Russia but suspended the case pending a favorable development in the internal situation. Ruling without costs, it referred the case back to the Federal Department of Justice and Police (FDJP) for a decision on the application of Art. 1a EIMP, which stipulates that cooperation must be compatible, in particular, with Swiss public policy. The case concerns funds[...]

Can PostFinance refuse to open a bank account on the grounds that the relationship would entail disproportionately high costs? In a brief ruling intended for publication, the Federal Court leaves the question wide open. However, it specifies that a customer wishing to take legal action to open a bank account cannot invoke the special consumer forum provided for in Art. 32 CPC (4A_115/2025 of 12 January 2026). In 2022, a foreign politician domiciled in Geneva applied to open a bank[...]

On several occasions, the Federal Court has left open the question of the obligation to return retrocessions in an execution-only relationship (see in particular Fischer, cdbf.ch/1338). In its judgment 4A_149/2025 of January 12, 2026, intended for publication, it ruled that the compensation received by a private bank in connection with the distribution of investment funds and structured products was not subject to restitution, given the circumstances. The relationship between the parties was one of execution only; however, the disputed remuneration[...]

Is an asset manager who receives retrocessions for ten years without informing his clients guilty of unfair management and can he be prohibited from practicing within the meaning of Art. 67 CP? The Federal Supreme Court answered both questions in the affirmative in its judgment 6B_431/2024 of November 10, 2025. In this case, an asset manager was accused of receiving retrocessions between 2006 and 2016 without informing his clients. The asset manager received 25% of the annual deposit fees, 60%[...]
