The United States Court of Appeals for the Second Circuit has upheld a lower court's decision to dismiss claims from bondholders against the Swiss Confederation. The bondholders, who held securities issued by Credit Suisse, argued that Switzerland unlawfully ordered the write-down of their investments as part of a merger with UBS Group AG. This ruling, made on July 16, 2026, is significant as it reinforces the protections afforded to foreign governments under U.S. law, specifically the Foreign Sovereign Immunities Act (FSIA).

The case, titled Creditincome Limited v. The Swiss Confederation (Docket No. 25-2733), centers around a controversial merger between two major Swiss banks. The bondholders claimed that Switzerland's actions in facilitating the merger constituted commercial activity, which would allow them to bypass the usual sovereign immunity protections. However, the court ruled that Switzerland's actions were sovereign in nature and thus immune from U.S. jurisdiction.

Credit Suisse was facing significant financial difficulties in late 2022 and early 2023, leading to its eventual acquisition by UBS. In response to the crisis, Swiss authorities took various measures to facilitate the merger, including negotiating terms, extending loans, and enacting emergency laws. The bondholders, who held approximately $372 million in Credit Suisse's Additional Tier 1 (AT1) securities, alleged that Switzerland's order to write down their investments to zero was unlawful.

The bondholders filed their claims in the U.S. District Court for the Southern District of New York, arguing that Switzerland lacked immunity under the FSIA's commercial activity exception. This exception allows for lawsuits against foreign states if the actions in question are commercial and have a direct effect in the U.S. However, the district court dismissed the case, stating that the actions taken by Switzerland did not meet the criteria for commercial activity.

The court noted that while some of Switzerland's actions could be characterized as commercial, the overall conduct surrounding the merger was distinctly sovereign. The court emphasized that Switzerland's coercive measures, including directing Credit Suisse to merge with UBS and enacting laws to facilitate the transaction, were not actions that could be performed by private entities.

In its ruling, the Second Circuit affirmed the lower court's decision, stating, "Switzerland's 'brokering' was not 'a commercial activity' for purposes of the FSIA." The judges highlighted that while Switzerland may have engaged in some actions that appeared commercial, the context and nature of those actions were fundamentally different from those of a private market player.

This ruling has significant implications for foreign sovereign immunity and the ability of investors to seek recourse in U.S. courts. The court's decision reinforces the principle that foreign governments are generally protected from lawsuits in the U.S., particularly when their actions are considered sovereign in nature.

The implications of this ruling extend beyond the immediate case. It serves as a precedent for future cases involving foreign states and their commercial activities, clarifying the boundaries of the FSIA's commercial activity exception. Investors and bondholders may need to reconsider their legal strategies when dealing with foreign governments, especially in cases involving significant financial transactions or mergers.

Looking ahead, it remains to be seen whether the bondholders will seek further legal recourse. The court's ruling does not prevent them from appealing to the Supreme Court, although such an appeal would need to address the specific legal standards set forth by the Second Circuit. Additionally, related cases may emerge as other bondholders challenge similar actions taken by foreign governments in the context of financial crises.

In summary, the Second Circuit's ruling in Creditincome Limited v. The Swiss Confederation underscores the robust protections afforded to foreign governments under U.S. law, particularly in matters involving sovereign actions. This decision not only impacts the bondholders involved in this case but also sets a precedent that could affect future legal disputes involving foreign sovereigns and their commercial activities.
