Swiss Sanctions 2026: Keeping Screening and Ownership Controls Current

Executive Overview

On 22 May 2026, Switzerland expanded its sanctions lists relating to Russia and Belarus, adopting various listings decided by the European Union as part of its 20th sanctions package. The Swiss measures included additional persons and entities subject to asset freezes and prohibitions on making funds available.

For companies, the practical lesson is that sanctions compliance is not limited to checking whether a contracting party's name appears on a list. Ownership and control, intermediaries, payment routes, goods and services, end use and changes during the life of a transaction can all affect the risk position, and each of them can change after onboarding.

Regulatory Background

Swiss coercive measures are periodically updated, and the May 2026 expansion follows that pattern. An asset freeze and a prohibition on making funds available operate on the substance of a relationship rather than on its label: the question is whether economic resources are made available, directly or indirectly, to a listed person or entity, which brings ownership and control structures directly into scope.

The new Swiss anti-money-laundering framework also reinforces attention to preventing breaches of coercive measures. In practice this means that sanctions screening and AML diligence draw on the same underlying facts about parties, ownership and flows, and that weaknesses in beneficial-ownership information affect both regimes at once rather than only one of them.

Why It Matters

Sanctions exposure rarely arises from a direct dealing with a listed party. It arises from the parts of a transaction that were not examined with the same care as the counterparty name.

• Groups with international suppliers, commodity exposure or logistics chains crossing higher-risk jurisdictions.
• Financial intermediaries and their counterparties, where payment routing can introduce exposure outside the contractual relationship.
• Trading and distribution businesses where end use and onward sale are not fully visible.
• Holding structures and family offices with participations whose ownership has changed since acquisition.
• International families and investors whose banking relationships depend on the group's compliance record.
• Boards and transaction committees responsible for approving deals under time pressure.
• Advisers and compliance functions required to evidence that controls were current at the time of the transaction.

Practical Issues to Review

1. 01Review screening frequency and confirm that relationships are re-screened as lists change, rather than only at onboarding.
2. 02Extend the analysis beyond the contracting party to ownership and control, including indirect holdings and changes since the relationship began.
3. 03Examine intermediaries, agents and payment routes, which can introduce exposure that the contractual counterparty analysis does not reveal.
4. 04Assess goods, services and end use where relevant, and record the basis on which the assessment was made.
5. 05Define escalation rules, including who decides when a match or a partial match stops a transaction, and how that decision is documented.
6. 06Align sanctions screening with anti-money-laundering diligence so that both draw on a single, current fact set about parties, ownership and flows.
7. 07Establish a monitoring routine for list changes and a defined response when a change affects an existing relationship.

TCC View

In TCC's view, sanctions risk should be embedded in transaction governance rather than handled as a screening task at the perimeter. Corporate, banking and tax teams need a common fact set on parties, ownership and flows before a transaction proceeds, because each of them otherwise works from a partial view. Where those views differ, the difference usually surfaces at the least convenient moment, when a payment is blocked or a banking relationship is questioned.

The second observation concerns time. Lists change regularly, and a relationship that was unproblematic at onboarding may not remain so. One-off checks create a record that shows diligence at a single point rather than throughout the relationship. The controls that hold up under scrutiny are those that can demonstrate what was known, when it was known and what was done in response.

Planning Note

Groups exposed to these corridors should confirm that screening procedures, ownership analysis and escalation rules are current, and that the responsibility for monitoring list changes is assigned rather than assumed. Documentation should record the state of knowledge at each decision point. Further changes to Swiss coercive measures should be expected, and control frameworks should be designed to absorb them as routine updates rather than as exceptional events.
