FINMA ISIL and Al-Qaida Sanctions: The 17 August SESAM Update

On 19 August 2026 FINMA flagged an update to the ISIL (Da’esh) and Al-Qaida sanctions notification tied to Ordinance SR 946.231.08. The trigger sits one step upstream: the UN Security Council’s ISIL (Da’esh) and Al-Qaida Sanctions Committee amended its list by decision of 14 August 2026, and the State Secretariat for Economic Affairs (SECO) adjusted the Swiss sanctions database, SESAM, on 17 August 2026. For a Swiss reporting officer, the relevant chronology is that the UN decision took effect on 14 August, SECO published the corresponding SESAM modification on 17 August, and FINMA published its notice on 19 August.

The FINMA notice points to the change; the obligations themselves sit in the ordinance and, for Liechtenstein, in a separate ordinance under its own sanctions law. When a UN listing changes under this regime, two operational gaps warrant attention: the gap between a screening hit and a freeze, and the gap between reporting a frozen asset and filing a money-laundering suspicion.

The dates that drive the re-screen

Four dates carry this change. Keep them in the record you use to evidence the re-screen:

• 14 August 2026: the UN ISIL (Da’esh) and Al-Qaida Sanctions Committee amended its consolidated list.
• 17 August 2026: SECO adjusted SESAM, the database that is authoritative for Switzerland, and published the change on its website.
• 19 August 2026: FINMA published its sanctions notification pointing supervised institutions to the SECO change; SECO also published a separate further list modification on this date, with entry into force on 18 August 2026.
• 21 March 2025: the date of the ordinance itself, SR 946.231.08, which was totally revised on that date and remains the governing text.

For the 14 August UN Committee decision, SECO published the corresponding SESAM modification on 17 August 2026, with entry into force stated as 14 August 2026. That version is no longer the current list: SECO published a further modification on 19 August, with entry into force on 18 August 2026. A current re-screen should therefore use the latest SESAM version, while the audit trail should retain the legal-effect and publication dates for each change.

What the FINMA ISIL and Al-Qaida sanctions notice obliges of Swiss firms

SR 946.231.08 is the Ordinance of 21 March 2025 on measures against certain individuals, groups, undertakings and entities associated with the ISIL (Da’esh) and Al-Qaida organisations. It rests on the Embargo Act, and it carries the standard set of Swiss financial measures: a freeze of funds and economic resources belonging to listed parties, a prohibition on making funds or economic resources available to them, and an arms embargo. Alongside those, it carries a reporting duty for frozen assets.

The operational sequence for a bank, securities firm or asset manager is narrow. A practical control response is to re-screen the customer, relationship and transaction data within the firm’s sanctions-screening perimeter against the current SESAM list. Where funds or economic resources fall within Article 3’s freeze scope, apply the freeze and availability prohibition, subject to the ordinance’s exceptions, and make the required report to SECO without delay. The freeze scope is broader than a listed-name match: it also covers the acting-on-behalf or instruction and ownership/control categories specified in the ordinance. SECO administers the sanctions programme; FINMA publishes the freezing measures and notifies supervised institutions through MyFINMA, but the report on a frozen asset goes to SECO, not to FINMA. The same SESAM route carries other Swiss list changes, including the FINMA Iran sanctions update.

Why “directly applicable” removes the waiting room

The FINMA notice states that the UN committee’s change is directly applicable in Switzerland. That phrasing sets the timing. Switzerland implements UN Security Council sanctions through Federal Council ordinances made under the Embargo Act and adopts changes to the UN ISIL and Al-Qaida list automatically, so a committee amendment takes legal effect without a separate Swiss enactment for each name. SECO then reflects it in SESAM.

The misread here is procedural. A firm cannot treat the FINMA news item as the start of a grace period, and there is no separate Swiss transposition step to wait for. The change bound Swiss firms from the point it became applicable and was mirrored in SESAM on 17 August 2026. Anyone benchmarking against the way the EU enacts sanctions screening through Council regulations should note that the Swiss autonomous route reaches the same underlying UN list by a different legal path.

Liechtenstein runs on its own instrument

Liechtenstein sits inside the customs and monetary space shared with Switzerland, which tempts firms with cross-border books to treat one screening result as covering both. The legal bases are separate. Liechtenstein applies the ISIL and Al-Qaida measures through its own ordinance, LR 946.222.22 (LGBl 2011 Nr. 465, as amended), issued under the International Sanctions Act (ISG, LGBl 2009 Nr. 41). The ordinance title was amended by LGBl 2017 Nr. 255; LGBl 2023 Nr. 181 amended Annex 2 rather than the regime’s title.

The reporting channel is the difference that shows up in a file. Under Article 6 of the Liechtenstein ordinance, persons and organisations that hold or manage funds, or know of funds or economic resources presumed to fall under the Article 2(1) freeze, must report to the Stabsstelle FIU without delay. Banks and securities firms that have reported funds they hold or manage must also send the FIU, annually by 15 February, the amounts as at 31 December of the previous year; credits under Article 2(2c) are separately reportable without delay. Reports must include the beneficiary names and the object and value of the frozen funds and economic resources, and for such credits the issuer names. Applications for exception permits are submitted to the Stabsstelle FIU under Article 2(4). A Liechtenstein freeze report under Article 6 goes to the Stabsstelle FIU, not to SECO.

From screening alert to freeze: applying the identifier check

When a list moves, the first output is a set of screening alerts, and an alert is a candidate for review. In both ordinances, the freeze extends beyond funds and economic resources owned or directly or indirectly controlled by listed parties: it also reaches the additional acting-on-behalf or instruction and ownership/control categories specified in the respective provisions. A name that resembles a listed name, or a common transliteration of an Arabic name, is a match to investigate against the identifiers the annex supplies: date and place of birth, passport or national identification number, and known aliases.

The list annex is built for this problem. UN-listed individuals carry permanent reference numbers and entries with four numbered name fields, together with aliases and available identifiers; entities and other groups instead use a single Name field with aliases where available. These identifiers support resolution of potential matches across naming variants. Treating a raw name hit as an automatic freeze over-blocks; clearing it without documenting the identifier check under-evidences the decision. What triggers the freeze is identity plus the ownership or control link, and string similarity by itself does neither.

Sanctions freezing and AML suspicion are two files

A confirmed listed party usually raises a second question: does this also require a suspicious activity report? The two duties run on separate tracks. The sanctions freeze and the report of frozen assets are administered by SECO in Switzerland and by the Stabsstelle FIU in Liechtenstein. In Switzerland, FINMA states that where suspicious indicators arise, a financial intermediary must carry out additional clarifications under Article 6 AMLA and, if those indicators cannot be dispelled, make the Article 9 report to MROS without delay. In Liechtenstein, Article 17 of the Due Diligence Act requires an immediate written report to the FIU where there is suspicion of money laundering, a predicate offence, organised crime or terrorist financing. FINMA notes that Switzerland implements terrorist-asset-freezing through both the structures of its anti-money-laundering legislation and ordinances under the Embargo Act, so one customer can generate obligations on both tracks at once.

The point for a reporting officer is to keep one report from standing in for the other. Freezing an account and notifying SECO does not discharge an AML suspicion that the facts independently raise, and filing with MROS does not satisfy the sanctions freeze and its SECO report. Map which desk owns which filing before the next list change, because the answer holds across the calendar.

Frequently Asked Questions

The UN change is dated 14 August but SECO updated SESAM on 17 August. Which date binds a Swiss firm?

The 14 August Committee change was directly applicable in Switzerland with effect from 14 August 2026; SECO published the corresponding SESAM modification on 17 August. Those dates should be distinguished in the audit trail. For a current re-screen, use the latest SESAM version, which SECO updated again on 19 August with entry into force on 18 August 2026.

A group has a Swiss bank and a Liechtenstein entity on one screening platform. Is one cleared hit enough for both?

The screening logic can be shared, but the legal obligations and the reporting authorities are not the same. A Swiss freeze report goes to SECO under SR 946.231.08; a Liechtenstein freeze report goes to the Stabsstelle FIU under LR 946.222.22. Each entity documents its own decision against the instrument that binds it.

If a name is removed from the UN list, does the Swiss freeze lift automatically?

Under the Swiss automatic-adoption framework, UN list changes take effect without a separate enactment, so SESAM publication should not be described as the legal trigger for a delisting. Distinguish the applicable legal-effect date from SECO’s publication date, verify the current SESAM entry, and check whether another applicable sanctions regime still captures the same party before releasing assets.

• Liechtenstein obligations run under LR 946.222.22 and the ISG, and freeze reports go to the Stabsstelle FIU, not to SECO.
• The freeze scope includes the ownership, direct or indirect control, acting-on-behalf or instruction, and related controlled-entity categories specified in the applicable ordinance; a raw name alert should be resolved against the available identifiers before a match decision is made.

The next list change will take the same road

On 14 August 2026 the UN Committee amended the consolidated list; SECO published the corresponding SESAM modification on 17 August with entry into force on 14 August. That version was superseded by a further UN Committee update on 18 August and a SECO modification published on 19 August with entry into force on 18 August. Swiss and Liechtenstein entities should therefore distinguish the legal-effect date from the database-publication date, use the current applicable list, and route any sanctions report to the authority specified by the instrument that binds the entity.
