Swiss sanctions against Russia – Further alignment with the EU – Implementation of the 18th Sanctions Package

Swiss sanctions against Russia – Further alignment with the EU –…

In a continued effort to align with European Union ("EU") sanctions, on 29 October 2025, the Swiss Federal Council implemented further measures transposing the core elements of the European Union's 18th sanctions package adopted on 18 July 2025. The new Swiss measures entered into force on 30 October 2025 and reinforce the existing framework through expanded trade restrictions, energy-sector prohibitions, transaction bans affecting Russian financial institutions and sovereign funds, as well as new software and service restrictions, while enhancing procedural shields against foreign proceedings for Swiss operators. For reference, the European Union has already moved to a 19th sanctions package, and certain elements of the 18th package adopted at EU level, such as the measures relating to some Chinese financial institutions, are not included in the present Swiss revision.

OFAC sanctions enforcement against Interactive Brokers: Important compliance lessons (also) for Swiss financial institutions

OFAC sanctions enforcement against Interactive Brokers: Important…

On 15 July 2025, the U.S. Department of the Treasury’s Office of Foreign Assets Control ("OFAC") announced a settlement with Interactive Brokers LLC ("IB"), a U.S.-based global brokerage firm. The case, which resulted in a penalty of nearly USD 12 million, arose from compliance deficiencies related to sanctions screening, client location controls and oversight of introducing brokers. Although the enforcement action concerns U.S. regulations, it offers highly relevant lessons for Swiss financial institutions. In particular, the case illustrates how U.S. authorities evaluate the effectiveness of sanctions compliance frameworks in digital and cross-border contexts. OFAC’s findings underscore the importance of integrating technical access controls (e.g., IP filtering), robust screening and escalation procedures, as well as careful oversight of third-party introducers.
