FINMA Updates Taliban Sanctions List: What Swiss Financial Intermediaries Must Do

Switzerland's financial regulator FINMA has notified financial intermediaries, including virtual asset service providers, of an urgent update to the Taliban-related sanctions list. The change originates from a UN Security Council sanctions committee decision dated 13 April 2026 and became directly applicable in Switzerland on 14 April 2026, when the State Secretariat for Economic Affairs (SECO) updated its SESAM database. Firms that have not yet reviewed their screening workflows against the revised list need to act immediately.

What Changed and Why It Matters

The UN Committee Decision

On 13 April 2026, the relevant UN sanctions committee amended the list of individuals, companies, and organisations subject to measures under Switzerland's Ordinance on measures concerning persons and organisations associated with the Taliban (SR 946.231.07, dated 21 March 2025). The amendment modifies the set of designated parties covered by that ordinance, meaning some entries will have been added, modified, or otherwise revised.

Because Switzerland applies UN Security Council sanctions through domestic ordinances that incorporate the relevant UN lists by reference, the committee's decision takes effect in Switzerland without requiring separate parliamentary approval. SECO updated SESAM the following day, on 14 April 2026, making the revised list the operative screening reference for all Swiss financial intermediaries from that date.

SESAM as the Authoritative Swiss Screening Reference

SESAM (SECO Sanctions Management) is the Swiss government's official consolidated sanctions database. It reflects not only UN list changes but also autonomous Swiss measures. For compliance teams using digital asset accounting software or broader financial crime screening tools, SESAM is the source of truth for Swiss-law purposes. Any screening tool or crypto bookkeeping software workflow that pulls sanctions data must be validated against SESAM updates, not solely against third-party aggregated lists, which may lag behind official publication.

Obligations for Financial Intermediaries

Immediate Asset Freeze

Swiss financial intermediaries are required under the ordinance to implement the prohibitions without delay and to freeze any assets belonging to, or controlled by, designated persons or entities. For crypto-asset service providers and other firms handling digital assets, this means checking all active wallets, accounts, and pending transactions against the updated SESAM list and placing an immediate hold on any matched positions.

Reporting to SECO

Where a business relationship is affected, firms must report it to SECO. The FINMA notice is explicit on one point that is sometimes misunderstood: a SECO report does not discharge the intermediary's separate obligations under Switzerland's Anti-Money Laundering Act (GwG). Specifically:

• If suspicion remains after a SECO report, the firm must conduct additional clarifications under Article 6 GwG.
• If those clarifications do not resolve the suspicion, the firm must file a separate suspicious activity report with the Money Laundering Reporting Office Switzerland (MROS) under Article 9 GwG, without delay.

This dual-track obligation is a compliance gap that auditors regularly identify during AML reviews of Swiss financial institutions. The SECO report and the MROS report serve different legal purposes and neither substitutes for the other.

Documentation and Audit Trail

Whether or not a match is found, firms should document the screening run: the date, the SESAM version consulted, the outcome, and the name of the compliance officer who reviewed it. For firms using crypto accounting software to manage digital asset portfolios, this audit trail should sit alongside the transaction records so that any regulatory inspection can trace the screening decision back to the specific SESAM update that triggered the review.

Implications for VASPs and Digital Asset Firms

On-Chain Screening Considerations

For virtual asset service providers, sanctions compliance is not limited to KYC records. Wallet-level screening is increasingly expected by Swiss supervisory practice. A designated individual or entity may interact with a VASP through an address not previously linked to their identity in any KYC file. Firms should ensure their on-chain monitoring processes are refreshed against the updated SESAM list and that any transaction touching a newly designated address is flagged for immediate review.

Record-Keeping Under Swiss AML Rules

Swiss AML rules require that records supporting a freeze decision or a suspicious activity report be retained for a minimum period. Firms should confirm their crypto accounting software or digital asset accounting software captures not only the financial records but also the compliance decisions and supporting screening evidence in a format that can be produced to FINMA or SECO on request.

This update follows a pattern of active Swiss sanctions list maintenance. For a comparable earlier example from FINMA, see our coverage of FINMA's earlier Hamas and PIJ sanctions update, which raised similar dual-reporting obligations for Swiss intermediaries.

Action Checklist for Compliance Teams

Immediate Steps

Compliance officers and their advisors should work through the following before close of business:

• Pull the current SESAM list from the official SECO portal and confirm the date of the version you are screening against.
• Run a full re-screen of all active client relationships, wallets, and pending transactions against the updated list.
• Freeze any matched assets and document the freeze decision with a timestamped record.
• Notify SECO of any affected business relationships in accordance with the ordinance's reporting procedure.
• Separately assess whether the circumstances also require additional clarification under Article 6 GwG and, if suspicion cannot be dispelled, file with MROS under Article 9 GwG.
• Retain all screening records, freeze decisions, and reports in your AML documentation system.
