Switzerland updates Iran sanctions list
Swiss financial intermediaries must update Iran-sanctions controls after SECO's SESAM change
FINMA
·
Change
Switzerland updated its SESAM sanctions database for Iran-related sanctioned persons, companies and organisations, with the amendment entering into force on April 14, 2026 at 23:00.
Why it matters
The SESAM update changes Switzerland's operative Iran sanctions list. Swiss financial intermediaries must update screening controls, implement the prohibitions, freeze assets of sanctioned persons and report affected business relationships to SECO, while still completing AML enquiries and MROS reporting where suspicion remains.
Implications
- — Swiss sanctions-screening teams must update customer and transaction-screening controls with the amended SESAM Iran-sanctions entries from April 14, 2026 at 23:00.
- — Swiss financial intermediaries holding assets of sanctioned persons must freeze those assets and report affected business relationships to SECO under the Ordinance.
- — AML compliance teams at Swiss financial intermediaries must continue Article 6 AMLA enquiries and file with MROS under Article 9 AMLA if suspicion cannot be cleared, because SECO reporting does not replace AML reporting duties.
