A Swiss-headquartered trading group is onboarding a new counterparty. The compliance team runs a screening check against SECO's lists. One match returns – but the name is a partial hit, the entity's registered address has changed twice in eighteen months, and a beneficial owner of record holds just under fifty percent. The deal is under time pressure. What happens next determines whether the group faces a reportable breach or a cleared transaction.
Name and entity screening under the Swiss State Secretariat for Economic Affairs (SECO, Switzerland's authority for economic sanctions and export controls) requires a structured, defensible process. Businesses must screen counterparties, owners, and related parties against the Swiss sanctions lists published under the relevant SECO ordinances – and a single gap in the ownership chain, a missed alias, or an untested control relationship can expose a business to civil and criminal liability under Swiss law.
This page explains the legal basis, the screening procedure, the ownership and control tests that apply, how the Swiss position compares with OFAC and OFSI, and how Calder & Vance assists businesses building or fixing their SECO screening programme.
What is the legal basis for name and entity screening under SECO?
SECO administers Switzerland's autonomous economic sanctions and implements UN Security Council measures through a series of thematic ordinances, each targeting a specific sanctions programme. These ordinances prohibit dealings with designated persons and entities, freeze assets, and restrict economic activity. The Swiss Federal Act on the Implementation of International Sanctions (the "Embargo Act") and the relevant thematic ordinances together form the operative legal basis.
Compliance with these instruments is not optional for Swiss-domiciled persons and entities. It also extends to Swiss-controlled foreign subsidiaries where a Swiss parent directs or enables a transaction. Non-Swiss businesses with a connection to Switzerland – through a Swiss bank, a Swiss correspondent, a Swiss affiliate, or Swiss-originating goods – face parallel exposure. The practical consequence is that SECO screening obligations can reach well beyond the Swiss border.
SECO publishes and maintains its own consolidated sanctions lists. These sit alongside the UN Security Council Consolidated List, which Switzerland implements domestically, and Switzerland's autonomous lists, which in some programmes are broader than the UN baseline. Screening against only one of these sources is a common and costly error.
How does the SECO screening procedure work in practice?
An effective SECO screening programme operates across four sequential stages: list identification, data input quality, match analysis, and decision documentation. Each stage carries specific failure modes that experienced compliance teams learn to control.
The first stage requires confirming which SECO ordinances apply to the counterparty relationship in question. Not every ordinance is active for every business; the relevant thematic lists depend on the goods, the sector, the counterparty's jurisdiction, and the nature of the transaction. Applying the wrong list – or omitting a relevant one – undermines the entire exercise.
Data quality at the input stage is where many programmes break down. A counterparty's legal name, registered address, date of incorporation, and any known aliases must all be submitted to screening. In our experience, businesses routinely screen only the trading name they know, missing the registered legal entity name, the holding company above it, and any intermediate layer between the trading entity and its ultimate beneficial owner.
Match analysis requires a human decision on every potential hit. Automated screening tools return alerts; they do not return decisions. A qualified reviewer must assess name similarity, geography, date-of-birth or incorporation data, and the ownership and control picture. The final stage is documentation: a recorded rationale for every cleared match, time-stamped and signed, that can be produced to SECO or to a Swiss financial-market supervisor on request.
What is the ownership and control test under SECO, and how does it compare with OFAC and OFSI?
Switzerland applies an ownership and control test: a non-listed entity is treated as caught by a sanctions ordinance if a designated person owns or controls it to a sufficient degree. The threshold and the mechanics of the control analysis differ from the US and UK positions, and those differences matter for any cross-border business managing multiple simultaneous screening obligations.
Under OFAC, the test is largely mechanical. The 50 percent rule (OFAC's rule treating entities owned 50 percent or more by one or more blocked persons in the aggregate as themselves blocked) applies regardless of control or management arrangements. 50 percent or more aggregate ownership is the bright line. Below that line, ownership alone is generally insufficient, though OFAC can designate directly.
Under OFSI in the United Kingdom, the ownership and control test is broader. A non-listed entity can be caught if a designated person owns it, controls it directly or indirectly, or acts on its behalf or at its direction. The control prong reaches management arrangements and contractual relationships that the US mechanical rule does not touch.
The Swiss position under the relevant SECO ordinances combines elements of both. Ownership analysis is required, and control relationships – including indirect control through intermediate entities and nominee arrangements – are in scope. For a business managing SECO exposure alongside OFAC and OFSI obligations, the ownership analysis must be run separately under each regime. Clearing a counterparty under OFAC's mechanical test does not clear it under the Swiss or UK positions. Have you applied all three tests to the same ownership chain?
The cross-border interaction becomes acute in practice when a listed person holds a stake below fifty percent in a Swiss target but exercises board-level control, or where nominee arrangements obscure the beneficial ownership picture. In those situations, the SECO analysis may conclude that the entity is caught even when the US mechanical test would not. We regularly advise businesses facing exactly this divergence.
What are the specific risk flags that disrupt screening outcomes?
Several patterns produce the highest proportion of compliance failures in SECO-related screening. Understanding them in advance allows a screening programme to address them by design rather than by retrospective remediation.
Partial-name matches are the most frequent source of incorrect clearances. Transliterated names from Arabic, Cyrillic, or Chinese scripts produce multiple spelling variants. A screening tool configured only for exact or near-exact matches will miss phonetic equivalents and deliberate character substitutions. The configuration of fuzzy-matching logic – and its sensitivity threshold – is a compliance decision, not a technical one.
Alias and former-name gaps arise when a designated entity has been listed under a name that no longer appears on its current commercial registration. SECO list entries carry aliases where known, but the information is not always complete. A diligent programme checks primary sources – national company registries, beneficial-ownership registers, and UBO filings where available – and does not rely on the list entry alone.
Ownership chain opacity is the structural risk. A target entity may be clean on the SECO list, but a designated person may sit two or three layers above it in the holding structure. In our practice, we see this pattern most frequently in structures that cross multiple jurisdictions and use intermediate holding vehicles in low-disclosure environments.
Trigger-event gaps are another recurring problem. Screening at onboarding without rescreening on a defined periodic basis – or on a material trigger such as a change in ownership, a new transaction, or a new sanctions designation – produces a false sense of security. SECO lists are updated as designations are added or removed; a counterparty cleared six months ago may not be clear today.
Finally, documentation failures are the risk that turns a manageable error into a serious enforcement matter. A regulator reviewing a transaction will ask to see the screening record: when it was run, against which lists, who reviewed the match, and what decision rationale was recorded. An absence of documentation shifts the analysis from "incomplete process" toward "deliberate non-compliance".
How does SECO screening interact with other major regimes?
Switzerland is not an EU member state, but SECO's autonomous sanctions programmes track EU Council designations closely in many areas. A counterparty caught under EU sanctions will frequently – though not invariably – appear on SECO's lists as well. However, the reverse is not guaranteed: SECO may maintain designations the EU has not adopted, and EU listings do not automatically produce SECO exposure for a Swiss-domiciled business. Screening against EU lists alone is not a substitute for SECO-specific screening.
For businesses with US operations or US-dollar payment flows, OFAC exposure runs in parallel with SECO obligations. Secondary-sanctions risk – the risk that a non-US business conducting a transaction with a SECO-designated person could attract OFAC's attention if the transaction has any US nexus – requires separate analysis. OFAC's extraterritorial reach means that a transaction cleared under SECO may still present OFAC risk, particularly where USD clearing, US financial institutions, or US-origin goods are involved.
UK businesses or businesses with OFSI-supervised payment flows face a third concurrent analysis. The OFSI ownership and control test, described above, may produce a different answer from both the SECO and OFAC analyses. Where all three regimes are in play, the operational question is whether a single counterparty-file can support three simultaneous clearance decisions, each documented under the relevant regime's standard. In our cross-border practice, we design screening programmes that produce regime-specific documentation from a single data-gathering exercise, reducing duplication without conflating the analyses.
The UN Consolidated List sits beneath all three regimes. Switzerland implements UN Security Council measures directly. A designation on the UN list generally produces automatic SECO exposure. But SECO's autonomous lists frequently extend further than the UN baseline, and OFAC and OFSI run their own designations outside the UN framework. Screening only the UN Consolidated List satisfies none of the three domestic-regime obligations.
When should a business involve specialist sanctions counsel for SECO screening?
Some screening situations are straightforward; others are not. A clean no-match on a clearly identified, single-jurisdiction counterparty needs documentation, not counsel. But several scenarios move the analysis beyond what an internal compliance team should resolve alone.
A potential match on a SECO list – even a partial or uncertain one – requires an immediate hold on the transaction and a structured legal analysis. Acting on an uncertain match without counsel risks two opposite errors: blocking a legitimate transaction unnecessarily or clearing a genuinely prohibited one. Both have consequences. The first damages commercial relationships; the second creates regulatory exposure.
Opacity in the ownership chain is a trigger for specialist involvement. Where beneficial-ownership information is incomplete, contested, or structured across multiple jurisdictions, the ownership analysis requires legal judgment, not only screening-tool output. We assess ownership chains against the relevant SECO, OFAC, and OFSI tests and provide a written opinion that can be retained on the compliance file.
A potential historic breach – a past transaction that may have involved a now-designated or previously designated person – requires an immediate assessment of exposure and options. Switzerland's Embargo Act provides for both civil and criminal consequences. Early legal involvement in such situations allows the full range of options to be considered, including voluntary disclosure where that route is open and appropriate.
Programme design and stress-testing are appropriate matters for external counsel at the point of initial build or following a significant change in the business – a merger, an acquisition, a new product line, or entry into a new market. Internal teams build programmes that reflect their existing knowledge; external review identifies the gaps that internal familiarity obscures.

A common misconception about SECO screening
The most persistent myth in SECO compliance is that a business running EU sanctions screening does not need to run a separate Swiss analysis. This view is wrong, and the cost of relying on it can be significant.
Switzerland and the EU maintain their sanctions lists independently. SECO may add or remove designations on a different timeline from the EU Council. SECO's autonomous programmes in some areas extend beyond EU designations. And the EU lists themselves are not a complete substitute for SECO-specific screening even where the designations overlap, because the implementing instruments differ and the documentation standards required under Swiss law are specific to the Swiss regime.
The same misconception arises in reverse: some businesses assume that a clean SECO result covers their OFSI or OFAC exposure. It does not. Jurisdictional coverage is not transferable. Each regime requires its own documented analysis, and each produces its own legal consequences for a failure.
In our experience, this assumption is most common among businesses that began their sanctions programmes in a single-jurisdiction environment and expanded internationally without updating their compliance infrastructure to match. The cost of correction is proportionate to how long the gap has been running.
How Calder & Vance assists with name and entity screening under SECO
Calder & Vance provides specialist support at every stage of a SECO screening engagement. Our work is structured around the specific legal and operational questions that arise in Swiss sanctions compliance, and it extends to the cross-regime dimensions that a Swiss-only analysis will miss.
For businesses establishing or redesigning a screening programme, we assess the current architecture against the SECO list structure, the ownership and control tests, and the documentation requirements of the relevant SECO ordinances. We identify configuration gaps in the screening tool, gaps in the data gathered at onboarding, and gaps in the periodic rescreening and trigger-event processes.
For businesses managing a specific match or a potential breach, we provide a legal analysis of the ownership and control position, assess the risk of prohibition under the applicable SECO ordinance, and advise on the appropriate next step – including voluntary disclosure where that option is available and appropriate.
For businesses operating across SECO, OFAC, and OFSI simultaneously, we design a single counterparty-file structure that generates regime-specific clearance documentation from a unified data-gathering process. This removes the duplication that arises when three separate teams run three separate processes against the same counterparty, and it ensures that each regime's documentation standard is met independently.
In a recent matter, a financial services group with Swiss and UK operations discovered that its existing screening tool was configured only for the EU Consolidated List and the UN Consolidated List. SECO's autonomous list entries were not being checked at all. We conducted a retroactive screening exercise against the SECO lists, identified a small number of prior transactions requiring further assessment, and redesigned the programme to incorporate SECO list updates on an automated feed. The group now maintains a single compliance file for each counterparty that documents clearance under each of the three applicable regimes.
The position above covers the standard configuration for SECO screening. Your facts – the counterparty's jurisdiction, ownership structure, the sector, the transaction type, and the regimes simultaneously in play – change the analysis materially.
