From Policy to Prosecution: Are Sanctions Against Russia Finally Working?

The UK’s first successful criminal prosecution under the Russia (Sanctions) (EU Exit) Regulations 2019 signals a long-awaited shift from policy rhetoric to legal enforcement. Dmitrii Ovsiannikov, a former Russian deputy minister and sanctioned figure since 2017, was convicted for sanctions breaches and money laundering after entering the UK, opening bank accounts, and receiving over £76,000 in illicit funds.

For financial institutions, this development carries weight beyond headlines—it marks a turning point where sanctions can no longer be dismissed as symbolic. This case offers a critical opportunity to assess whether Western sanctions against Russia are indeed working.

The Significance of the Ovsiannikov Case

Dmitrii Ovsiannikov, the former governor of Sevastopol in Russian-occupied Crimea and a former deputy industry minister, was sanctioned by the UK in 2017 for his role in undermining Ukrainian sovereignty. Despite this, he travelled to the UK in 2023, obtained a British passport through his British-born father, opened bank accounts, purchased a luxury vehicle, and received substantial financial support from family: all in violation of UK financial sanctions.

His conviction in April 2025 underlines a new chapter in UK sanctions enforcement: one marked not just by policy declarations but by active criminal prosecution. His brother, Alexei, was also convicted for facilitating these breaches, while his wife, Ekaterina, was acquitted.

The significance of Ovsiannikov’s conviction lies not only in its legal outcome but in what it reveals about enforcement readiness. Although the regulations enabling this prosecution have been in place since 2019, it has taken over five years for UK authorities to convert statute into sentence. That delay, while concerning, should not obscure the bigger picture: the UK has demonstrated it has the institutional capacity and political will to enforce its autonomous sanctions regime. This enforcement breakthrough provides a new legal precedent for holding both sanctioned individuals and their facilitators accountable under UK law.

Crude Disruption: Sanctions on Russia’s Shadow Oil Fleet

Beyond this single case, there is a growing body of evidence that sanctions against Russia are exerting measurable pressure economically, technologically, and financially. The oil price cap mechanism implemented by the G7 and EU in late 2022 initially allowed Russia to reroute its crude exports via a “shadow fleet” of older tankers insured outside Western markets.

However, recent US Treasury actions have begun to dismantle this workaround by targeting shipping facilitators, vessel owners, and front companies. Combined with tightened marine insurance controls in the UK and EU, these efforts have sharply increased the operating costs and risks for traders engaged in Russia-linked energy transport.

Tech Chokehold: Export Controls Bite Deep

In the tech sector, Russia’s industrial and military capabilities have taken a serious hit due to export controls on semiconductors, avionics, and dual-use components. Industry analysts report that Russian imports of advanced chips dropped by over 70% between 2022 and 2024. Deprived of legitimate supply chains, Russian manufacturers have resorted to sourcing disassembled second-hand electronics from intermediary countries.

For financial institutions involved in trade finance or logistics, this means growing compliance exposure to transshipment hubs in Central Asia, Turkey, and the UAE; all jurisdictions now under heightened scrutiny by Western regulators.

Financial Isolation & Economic Fragmentation

Meanwhile, financial isolation continues to erode the structural foundation of Russia’s economy. The freezing of approximately $300 billion in Russian state asseets and the exodus of more than 1,200 foreign companies have left the country reliant on domestic substitutes and parallel market structures. Access to global capital markets remains effectively closed, and foreign direct investment has slowed to a crawl. This decoupling, while not immediate, is reshaping the Russian economy in ways that will limit its long-term capacity to fund external aggression.

Setback or Shift? The Disbandment of Task Force KleptoCapture

One development that complicates this otherwise strengthening enforcement narrative is the disbandment of the US Department of Justice’s Task Force KleptoCapture in early 2025. Formed in 2022, the task force was instrumental in identifying and seizing over $700 million in Russian-linked assets, and in pursuing oligarchs, enablers, and facilitators across jurisdictions.

Its dissolution raises valid concerns about the future trajectory of US sanctions enforcement. Without a dedicated, centralised unit, investigations into complex cross-border evasion schemes may lose momentum. The DOJ has indicated that ongoing cases will continue, but the absence of a flagship enforcement body could reduce deterrent pressure particularly if perceived by illicit actors as a weakening of US resolve.

For financial institutions, the change reinforces the imperative to maintain strong internal compliance infrastructure regardless of shifting government enforcement structures. As public enforcement potentially scales back, private-sector due diligence and monitoring must step up to fill the gap. This is particularly crucial for institutions with exposure to jurisdictions previously highlighted by KleptoCapture such as the UAE, Turkey, Cyprus, and Hong Kong.

A Global Pattern: Prosecutions & Coordination Beyond the US

Despite the loss of KleptoCapture, the global trend toward more aggressive sanctions enforcement continues. The EU is building a new coordination body to align enforcement across member states. The UK has now demonstrated its readiness to criminally prosecute breaches. OFAC in the U.. is still highly active, particularly with secondary sanctions and entity listings aimed at third-party facilitators in Asia and the Middle East.

The lesson for compliance teams is clear: enforcement is no longer the sole domain of a few flagship unit. It is becoming embedded in the institutional strategies of multiple governments, operating through cooperation, asset freezes, and coordinated designation regimes.

Strategic Lessons for Financial Institutions

These developments demand a recalibration of how financial institutions manage sanctions risk. The Ovsiannikov case highlights the need for dynamic and intelligence-driven sanctions screening. Conventional list-matching is no longer sufficient, especially when designated individuals exploit dual nationality, familial ties, or shell companies to re-enter the financial system. Enhanced due diligence , transaction behaviour monitoring, and cross-jurisdictional entity mapping are no longer best practices; they are minimum expectations.

Furthermore, financial institutions must begin evaluating 'proximity risk' and the indirect exposure that arises through clients, counterparties, or associates of sanctioned individuals. The conviction of Ovsiannikov’s brother for facilitating financial transactions illustrates how legal liability is expanding beyond direct violators. This has implications for onboarding processes, client reviews, and transaction monitoring, particularly in wealth management, private banking, and cross-border services.

Conclusion: From Fragility to Framework

Whilst sanctions against Russia have not yet achieved all their geopolitical aims, there is mounting evidence that they are working by disrupting supply chains, isolating financial networks, and, increasingly, being enforced through the legal system. The UK’s prosecution of Ovsiannikov, paired with ongoing international coordination, illustrates that enforcement is becoming more than aspirational.

That said, the disbandment of Task Force KleptoCapture is a reminder that political prioritisation shapes enforcement capacity. As US resources shift to other domains, the burden on financial institutions to detect and prevent evasion grows proportionally. In this evolving landscape, sanctions compliance must be proactive, resourced, institutionally embedded, and not just reactive.
