Regulatory Area
Sanctions Compliance
Sanctions are legal restrictions imposed by governments and international bodies to influence the behaviour of countries, organisations, individuals and other designated parties. They can restrict access to financial services, freeze assets, prohibit transactions, limit trade or investment, and prevent specified persons from receiving funds, economic resources or other benefits.

- What it is
- Key things to know
For regulated businesses, sanctions compliance means more than screening names against a list. Firms need to understand who they are dealing with, who ultimately owns or controls an entity, where funds and assets are moving, whether a transaction involves a restricted jurisdiction, and whether the activity may provide value to a sanctioned party.
Digital assets add further complexity. Crypto transactions can move across borders quickly, involve pseudonymous wallet addresses and pass through multiple platforms, protocols or self-hosted wallets. Effective sanctions controls therefore need to combine traditional screening with blockchain analytics, wallet intelligence, transaction monitoring and clear escalation procedures.
Key things to know
Sanctions regimes differ across jurisdictions
The UN, EU, UK, US and other jurisdictions maintain separate sanctions frameworks, designation lists, ownership tests, licensing arrangements and reporting requirements. A transaction may be permitted under one regime but restricted under another, depending on the parties, currencies, location, ownership structure and the firm's jurisdictional exposure.
Ownership and control matter as much as the listed name
An entity may be subject to sanctions even if it does not appear directly on a sanctions list. Firms need to assess whether it is owned or controlled by designated persons and apply the relevant aggregation, ownership and control tests under each applicable regime.
Crypto sanctions controls must go beyond blacklist screening
Name and address screening alone will not identify every wallet connected to a sanctioned person or entity. Effective controls require blockchain analytics capable of clustering related addresses, identifying behavioural links and detecting newly created wallets associated with sanctioned networks, particularly where operators regularly rotate infrastructure.
Indirect exposure requires a clear risk methodology
Firms need to define how indirect exposure is treated within transaction monitoring, including the relevance of transaction distance, value, direction of flow, timing and the nature of the intermediary wallets involved. Local regulatory guidance should be reflected where available, rather than relying on a universal "number of hops" threshold.
Timing of designation matters
Transactions completed before a person or entity was designated are not automatically treated in the same way as post-designation activity. However, firms may still need to assess the circumstances, preserve evidence and consider whether reporting, retrospective review or other action is required under the applicable regime.
Sanctions decisions need documented escalation
Potential matches and wallet exposure alerts require more than an automated risk score. Firms should have clear procedures for investigation, transaction holds, asset freezes, reporting, licence assessments and senior escalation, with the reasoning behind each decision properly recorded.
