Introduction
Western sanctions against Russia have not failed — they have performed exactly as the system allows them to. In a globalised economy built on interconnected markets, third-country intermediaries, and competing political interests, enforcement is not simply difficult — it is structurally constrained.
Western sanctions imposed following Russia’s full-scale invasion of Ukraine in 2022 have generated significant economic pressure. Nevertheless, this economic “slow poison” has not achieved the core strategic objective of altering Russia’s behaviour. While sanctions have increased the long-term cost of war, their impact has been uneven and diluted by evasion networks, regulatory gaps, and competing geopolitical priorities. As a result, their effectiveness depends less on scale than on the coherence and credibility of enforcement.
Key Findings
– Sanctions are systematically undermined by Russia’s ability to reroute trade through third countries and opaque supply chains.
– Enforcement within the EU remains structurally fragmented, limiting consistency and effectiveness.
– Global demand — particularly for energy — continues to sustain Russian revenues despite formal restrictions.
– Sanctions are increasingly shaped by broader geopolitical priorities, reducing their coherence as a strategic tool.
Sanctions Evasion Mechanisms
Russia has demonstrated a high degree of adaptability in mitigating the effects of sanctions through a combination of economic reorientation, logistical innovation, and financial adjustment.
New Markets
As trade with the EU has declined, Russia has shifted its economic activity towards non-Western partners. China has emerged as a central actor, both as a major importer of Russian energy and as a supplier of goods previously sourced from Europe. At the same time, Russia has expanded ties with countries such as India, Iran, and North Korea, securing alternative markets and maintaining export revenues.
Opaque Supply Chains
Russia has relied on intermediary states — including Turkey and Armenia — to facilitate continued access to restricted goods. These networks, often involving shell companies and complex trade routes, are deliberately opaque and difficult to regulate. While this increases transaction costs, it enables the continued flow of dual-use goods and other critical imports.
Shadow Fleet
A key component of Russia’s strategy has been the development of a “shadow fleet” of oil tankers operating outside standard regulatory frameworks. These vessels frequently obscure ownership structures and rely on deceptive practices to bypass sanctions. While effective in sustaining exports, this approach has increased operational costs and introduced inefficiencies.
Financial Adaptation
Russia has also adjusted to financial restrictions by expanding alternative payment mechanisms. This includes the use of foreign accounts, domestic payment systems, and increased reliance on Chinese financial infrastructure. While cryptocurrencies have been explored, their role remains limited in scale.
Enforcement Challenges
The effectiveness of sanctions is constrained by a range of legal, institutional, and operational challenges.
Legally, enforcement is complex and often limited in scope. While frozen Russian assets have been partially leveraged to support Ukraine, they have not been fully confiscated or repurposed. In the maritime domain, the absence of a dedicated EU enforcement body, combined with the lack of a clear mandate for NATO to intercept commercial vessels, limits oversight.
Institutionally, enforcement within the EU remains uneven. It depends heavily on the administrative capacity and political will of individual member states, resulting in inconsistencies. Continued imports of Russian energy by certain countries highlight these vulnerabilities.
Operationally, enforcement relies significantly on the private sector, which must interpret and apply complex regulatory frameworks across global supply chains. This creates opportunities for evasion and weakens overall effectiveness.
Structural Constraints
Beyond enforcement challenges, sanctions are limited by broader structural factors.
A key constraint is the tension between reducing dependence on Russian energy and managing economic costs. Despite sanctions, EU states continue to import significant volumes of Russian fossil fuels. In 2024, EU spending on Russian energy exceeded its financial support to Ukraine.
Sanctions are also affected by shifting geopolitical priorities. Policy decisions — particularly in the United States — are often shaped by wider strategic considerations, which can dilute the consistency of sanctions enforcement.
More broadly, the absence of fully coordinated global participation creates systemic “leakages” that Russia can exploit. In a globalised economic system, such gaps are difficult to eliminate.
Policy Recommendations
– Establish a centralised EU-level mechanism for sanctions enforcement to ensure consistency across member states.
– Strengthen export controls and monitoring of high-risk third-country trade flows.
– Expand the use of targeted measures against intermediary networks facilitating sanctions evasion.
– Disrupt the financial, insurance, and logistical infrastructure supporting the shadow fleet.
– Accelerate efforts to reduce European dependence on Russian energy.
