FINMA Sudan Sanctions Update: What Swiss Financial Intermediaries Must Do Now
Switzerland's Financial Market Supervisory Authority has published an urgent compliance notice following a change to the UN Sudan sanctions list. The amendment, adopted by the relevant UN sanctions committee on 28 April 2026, modifies the list of designated natural persons, companies, and organisations covered by the Swiss Ordinance on Measures against Sudan (SR 946.231.18). Under Swiss law, that change is directly applicable, and every financial intermediary operating in Switzerland is now required to act. For firms that handle digital assets, this is not an abstract regulatory update: it is a live screening and reporting obligation that demands an immediate operational response.
What Changed and When
The UN Committee Decision
The UN sanctions committee responsible for Sudan amended its consolidated list of designated parties on 28 April 2026. Because Switzerland automatically incorporates UN Security Council sanctions into its domestic legal order through the Sudan Ordinance (SR 946.231.18), no further legislative step was required for the change to take effect in Switzerland.
SECO's SESAM Database Update
The State Secretariat for Economic Affairs (SECO) updated its SESAM sanctions management database on 29 April 2026, the day after the UN committee decision. SESAM is the authoritative Swiss reference for sanctions screening: firms that rely on it for daily or transactional checks must treat the 29 April version as the operative baseline going forward. FINMA's notice, published on 1 May 2026, confirmed the update and reminded financial intermediaries of the specific obligations that now apply.
Core Obligations for Financial Intermediaries
The FINMA notice restates three distinct duties, each grounded in the Sudan Ordinance and the Swiss Anti-Money Laundering Act (GwG). Compliance teams should read them as sequential, not alternative.
Implement the Prohibitions
Financial intermediaries are required to apply all prohibitions set out in the Sudan Ordinance. That includes restrictions on making funds or economic resources available to listed persons or entities, directly or indirectly. For digital-asset businesses, this means screening wallet addresses, counterparty names, and beneficial owners against the updated SESAM list before executing any transaction.
Freeze Designated Assets
Any assets belonging to, or controlled by, a newly listed person or entity must be frozen without delay. The freeze applies to all forms of assets: bank balances, securities holdings, and digital assets alike. Intermediaries should document the freeze decision, the timestamp, and the specific entry in SESAM that triggered it.
Report to SECO
Affected business relationships must be reported to SECO. The FINMA notice is explicit that submitting this SECO report does not discharge the intermediary's separate obligations under the GwG. In other words, the sanctions report and the AML report are parallel tracks, not interchangeable ones.
The GwG Layer: When Suspicion Persists
This is the point where many compliance programmes underestimate their exposure. Even after an intermediary has screened, frozen, and notified SECO, the GwG imposes a further duty if suspicion cannot be dispelled.
Enhanced Clarification Under Art. 6 GwG
Article 6 of the Anti-Money Laundering Act requires intermediaries to conduct additional clarifications whenever there are grounds for suspicion relating to a business relationship or transaction. A hit against the updated Sudan list is exactly the kind of trigger that activates this duty. Firms must document what further due diligence was performed, what information was gathered, and what conclusion was reached.
Reporting to MROS Under Art. 9 GwG
If the enhanced clarifications fail to resolve the suspicion, the intermediary is required to file a report with Switzerland's Money Laundering Reporting Office (MROS) without delay, as required by Article 9 GwG. Delay is not permissible once the suspicion threshold is met and cannot be cleared. Firms that treat the SECO notification as the endpoint of their obligations risk a serious GwG breach.
Practical Steps for Compliance Teams
Screening and System Updates
Any crypto accounting software or digital asset accounting software used by the firm should be connected to, or validated against, the current SESAM data. Sanctions lists integrated at the technology layer reduce the risk of manual screening gaps, particularly for high-volume transaction environments. Firms relying on periodic batch screening rather than real-time checks should reassess that cadence in light of same-day or next-day UN list changes becoming effective immediately in Switzerland.
Documentation Standards
Each step in the response process needs a clear audit trail: the date of the SESAM check, the specific SESAM version consulted, the identity of the designated party matched, the asset freeze decision, the SECO report reference, and any GwG clarification notes. Swiss supervisory practice expects contemporaneous records, not retrospective reconstructions.
Escalation Protocols
Front-office staff and compliance officers handling digital asset transactions should know the internal escalation path when a sanctions match is identified. The decision to freeze assets and report to SECO should not wait for a scheduled weekly compliance meeting. Equally, the decision to escalate to MROS requires senior sign-off and legal review in most firm frameworks, so those chains of authority should already be documented and tested.
For Swiss-based or Switzerland-facing firms, this update sits alongside other recent FINMA compliance notices. Our earlier coverage of FINMA Hamas and PIJ sanctions obligations for Swiss intermediaries provides useful context on how the same three-stage obligation structure applies across different UN sanctions regimes. Firms handling cross-border digital asset flows may also want to review how OFAC SDN cryptocurrency addresses and compliance priorities interact with Swiss obligations when US-nexus counterparties are involved.

Frequently Asked Questions
Does the Sudan sanctions update apply to crypto asset service providers in Switzerland?
Yes. The Sudan Ordinance applies to all financial intermediaries as defined under Swiss law, and FINMA's supervisory perimeter includes licensed or registered crypto asset service providers. Screening and freezing obligations extend to digital assets held on behalf of clients.
If a firm reports a frozen account to SECO, is a separate MROS report still required?
Potentially yes. FINMA's notice makes clear that the SECO sanctions report does not substitute for an AML report to MROS under Art. 9 GwG. If enhanced due diligence under Art. 6 GwG fails to dispel suspicion of money laundering or terrorist financing, the MROS report is mandatory and must be filed without delay.
Where can firms access the updated Sudan sanctions list for Switzerland?
The authoritative source is the SECO SESAM database, updated on 29 April 2026. The SESAM list is available through the SECO website and is the reference Swiss intermediaries should use for compliance screening.
What counts as sufficient enhanced due diligence under Art. 6 GwG in this context?
The GwG does not prescribe a fixed checklist, but regulators expect firms to gather additional information about the origin of funds, the purpose of the relationship, and the identity of the beneficial owner. Documentation of what was requested, what was received, and what conclusion was drawn is essential. Where the information is insufficient to dispel suspicion, the MROS filing obligation is triggered.
How should crypto bookkeeping software integrate sanctions screening for Swiss compliance?
Ideally, any crypto bookkeeping software used in a Swiss compliance environment should support real-time or near-real-time validation against SESAM data, either through direct API integration or through a documented manual update process. Given that UN committee decisions can become effective in Switzerland within 24 hours, periodic weekly screening is unlikely to meet regulatory expectations for high-volume operations.
