Sanctions Enforcement Violations Cases: Holding Evaders Accountable

The sweeping sanctions imposed on Russia following its full-scale invasion of Ukraine have generated an equally sweeping enforcement challenge. Sanctioned entities and their intermediaries have worked systematically to evade restrictions — using shell companies, cryptocurrency, correspondent banking networks, and falsified shipping documents. Enforcement agencies — principally the US Treasury's OFAC, the Commerce Department's BIS, and European equivalents — have pursued a growing roster of enforcement actions, signaling that sanctions evasion carries real legal and financial risk.

OFAC Penalties on Banks

The Treasury Department's Office of Foreign Assets Control (OFAC) has levied penalties against financial institutions for processing transactions involving sanctioned Russian entities or circumventing sanctions restrictions. Between 2022 and 2025, OFAC settled enforcement cases involving both US and foreign banks that had processed dollar-denominated transactions through US correspondent accounts for sanctioned parties. Notable cases included a $28 million penalty against a mid-size European bank for processing transactions involving sanctioned Russian energy sector entities after the imposition of Sectoral Sanctions. Several smaller financial institutions in post-Soviet countries received OFAC Cautionary Letters — formal warnings short of a penalty — for less egregious compliance failures, prompting voluntary remediation programs.

Cryptocurrency Exchange Violations

Russia-linked actors have used cryptocurrency as a sanctions circumvention tool to move funds beyond the reach of the traditional banking system. OFAC designated the Garantex cryptocurrency exchange in 2022 — a Russia-based exchange that processed billions in cryptocurrency transactions, including funds from ransomware groups and sanctioned entities. Several other crypto exchanges received OFAC civil penalties for processing transactions for sanctioned Russian individuals. The DOJ Cyber Division coordinated with international partners to seize cryptocurrency accounts linked to Russian oligarchs and sanctions evaders, resulting in forfeitures totaling hundreds of millions of dollars. Blockchain analytics firms (Chainalysis, Elliptic) played a critical role in mapping transaction flows and providing evidence for enforcement actions.

Shipping Company Penalties

The Russia sanctions regime includes restrictions on maritime shipping — banning services to vessels transporting Russian crude oil above the G7 price cap and prohibiting insurance, finance, and port services for cap-violating shipments. OFAC designated multiple vessels from Russia's "shadow fleet" — aging tankers operated through opaque corporate structures to move oil outside the price cap — and imposed penalties on ship management and insurance companies that facilitated cap violations. The UK's OFSI (Office of Financial Sanctions Implementation) implemented parallel shipping enforcement, targeting companies providing maritime services to designated vessels. Several shipping registries in Gabon, Palau, and the Comoros Islands — which had flagged shadow fleet vessels — came under pressure to deregister sanctioned ships.

Supply Chain Due Diligence Failures

Companies in non-EU, non-US jurisdictions that supplied controlled goods to Russia — often through multiple intermediary layers — became targets for penalties and designations. OFAC's "50 percent rule" means that entities 50% or more owned by a single designated person are automatically treated as sanctioned regardless of explicit listing. Supply chain due diligence failures — where companies processed transactions without conducting adequate checks on beneficial ownership or end-user identity — have been the most common basis for OFAC civil penalties. The EU's sanctions packages increasingly included "no re-export to Russia" obligations on purchasers outside the EU that received controlled goods, creating liability for EU-based sellers who failed to include and enforce these contractual clauses.

BIS Enforcement Actions

The Bureau of Industry and Security has pursued the most aggressive export control enforcement campaign in its history in response to Russia's invasion. BIS actions include: adding hundreds of entities in Russia and third countries to the Entity List; issuing Temporary Denial Orders (TDOs) that immediately cut off all export privileges; criminal referrals to the DOJ for smuggling conspiracies involving electronics and aircraft parts; and "Don't Let This Happen To You" guidance documents publicizing enforcement cases to deter future violations. By 2025, BIS-supported criminal prosecutions had resulted in over 50 convictions for Russia-related export control violations, with sentences including both imprisonment and fines.

European Enforcement Framework

EU sanctions enforcement is fragmented across member state jurisdictions — each country's law enforcement and financial intelligence unit is responsible for national enforcement. This creates inconsistency: some member states have active enforcement programs while others have initiated few actions. The European Sanctions Enforcement Network (ESEN) was established in 2023 to coordinate cross-border enforcement and share intelligence. The EU's "Freeze and Seize" task force — a joint effort by the EU, G7, and Ukraine — has focused on identifying and immobilizing sanctioned Russian oligarch assets, yielding over €50 billion identified though much remains frozen rather than forfeited due to legal constraints.

Frequently Asked Questions

What is OFAC and what powers does it have?

OFAC (Office of Foreign Assets Control) is a Treasury Department unit administering US economic sanctions. It can levy civil penalties up to the greater of $356,579 or twice the transaction value per violation, and can refer criminal cases to DOJ for penalties up to $1M and 20 years imprisonment.

What is a "shadow fleet" vessel?

A shadow fleet tanker is a ship operating through opaque corporate structures — often flagged in permissive registries, insured through non-Western networks, and managed by obscure companies — to transport Russian oil outside the G7 oil price cap.

How does cryptocurrency enable sanctions evasion?

Cryptocurrency can be transferred pseudonymously across borders without relying on sanctioned banks or correspondent banking systems. Privacy coins and mixing services further obscure transaction trails, though blockchain forensics firms have become effective at tracing these flows.

What is the G7 oil price cap?

A G7 agreement allowing non-G7 countries to purchase Russian oil at or below $60/barrel while denying Western shipping, insurance, and financial services to transactions above that price, aimed at reducing Russia's oil revenue while keeping global supply stable.

Can foreign companies be penalized under US sanctions?

Yes — US sanctions have significant extraterritorial reach. Foreign entities that process US dollar transactions through the US financial system, use US-origin goods, or have US persons involved in their transactions can be subject to OFAC jurisdiction.
