New US Sanctions Targets

OFAC updated the Specially Designated Nationals and Blocked Persons (SDN) List on August 28, adding new persons and vessels. This is a high-priority update because any business interaction with these designated entities is strictly prohibited. Companies must immediately implement these updates in their screening software to prevent accidental dealings and avoid severe penalties. Our read: The specific targeting of vessels indicates a continued focus on maritime trade and the prevention of sanctions evasion.

US Capital Markets & Regulatory Shifts

The SEC is moving to simplify how certain European assets are handled in the US. On August 28, it proposed amendments to Rule 3a12-8 to include European Union debt obligations in the list of exempted foreign government debt. For managers, this proposal suggests a future where EU debt is easier to trade and manage under US law, potentially reducing the regulatory and reporting burden for cross-border capital flows.

Simultaneously, several US exchanges and the Financial Industry Regulatory Authority (FINRA) are updating their operational and governance frameworks. Effective August 28, new arrangements for the allocation of regulatory responsibilities are in place for a broad group of venues, including Nasdaq, NYSE, and Cboe. Additionally, the Long-Term Stock Exchange, Inc. updated its rules regarding statutory disqualifications—the criteria that legally bar certain individuals from participating in the securities industry. FINRA also proposed a change to the selection of arbitrators for industry disputes. These updates, along with a routine implementation delay for a rule change at Nasdaq ISE, reflect a refinement of exchange-level compliance and dispute resolution processes. Our read: These administrative shifts signal a trend toward more granular oversight of exchange personnel and governance.
