Sanctions enforcement action

TLT picks out the key points you shouldn't miss...

What’s this about?

The UK government’s latest sanctions enforcement update brings together recent monetary penalties, disclosure notices, and case studies from OFSI, HMRC, NCA, and OTSI. For the finance sector, the message is clear: enforcement is intensifying, and the risks of inadvertent breaches are rising. Financial institutions must act now to strengthen controls and ensure robust compliance.

Our Head of Risk and Financial Crime, Ben Cooper says... 

“These enforcement actions show that regulators expect financial institutions to be proactive, not reactive. The days of relying on legacy controls are over - firms must demonstrate real-time sanctions screening, prompt reporting, and a culture of compliance at every level.”

Enforcement is targeting financial institutions directly

OFSI's recent actions include significant fines and public disclosure notices against banks and financial services firms, highlighting the need for robust systems and controls.

Prompt reporting is essential

OFSI expects financial institutions to self-disclose suspected breaches immediately. Delays can reduce penalty discounts and increase reputational risk. In the Colorcon case, a four-month delay in reporting led to a lower discount on the penalty.

Ownership and control risks are under scrutiny

Recent guidance and enforcement actions stress the importance of identifying entities owned or controlled by designated persons, including subsidiaries and complex structures. Failure to screen for indirect ownership is a common compliance gap.

License management and frozen asset controls

Breaches often arise from improper maintenance of frozen assets or expired licences. Financial institutions must ensure that all transactions involving designated persons are properly licensed and reported, and that frozen assets are managed in line with OFSI requirements.

Sector-specific guidance and resources

OFSI has expanded its guidance for the finance sector, including threat assessments, compliance notes and annual reviews. These resources provide practical steps for improving sanctions screening, reporting, and staff training.

Civil and criminal penalties are rising

Recent penalties include £152,750 against Colorcon, £300,000 against Markom Management and £465,000 against HSF Moscow. The FCA and OFSI are working together to ensure that regulated firms face both financial and reputational consequences for breaches.
