The geopolitical events of the past four years have produced an unprecedented expansion of sanctions regimes — and an equally unprecedented divergence between the EU and US approaches. For financial institutions operating across both jurisdictions, the compliance challenge is no longer simply about screening against the right lists. It is about managing the growing conflicts between regimes, navigating blocking statutes, and maintaining a defensible compliance posture in an environment where the rules are changing faster than most compliance functions can adapt.
Where EU and US Sanctions Regimes Diverge
The most significant divergence between EU and US sanctions regimes currently relates to Russia-related measures. While both regimes target overlapping sets of designated persons and entities, the scope of sectoral sanctions, the treatment of energy transactions, and the application of secondary sanctions create material compliance conflicts for institutions with dual-jurisdiction exposure. The EU's blocking statute — updated in 2018 and increasingly enforced — creates a legal obligation for EU entities to refuse compliance with certain US secondary sanctions, placing compliance officers in an impossible position without a carefully structured legal and compliance framework.
Practical Compliance Strategies for Dual-Jurisdiction Institutions
The most effective approach to dual-jurisdiction sanctions compliance begins with a clear mapping of the institution's legal entities, their jurisdictional nexus, and the specific transactions and relationships that create cross-regime exposure. This mapping exercise — which AFINUR conducts as part of its sanctions framework design engagements — provides the foundation for a tiered compliance architecture that applies the appropriate regime to each entity and transaction type, while managing the conflicts through documented legal opinions, escalation protocols, and board-approved risk appetite statements.
The Technology Dimension: Screening Architecture for Complex Regimes
The rapid expansion of sanctions lists — OFAC's SDN list has grown by over 40% since 2021 — has exposed the limitations of legacy screening architectures. Institutions relying on batch screening processes, outdated fuzzy matching algorithms, or single-list coverage are generating both false positives (operational disruption) and false negatives (compliance exposure). AFINUR's technology advisory practice works with institutions to assess their screening architecture against the current sanctions landscape — identifying gaps in list coverage, matching quality, and escalation workflows.
