Pass-through sanctions risk refers to the exposure a financial institution faces when a sanctioned individual, entity, vessel, or jurisdiction indirectly accesses the financial system through an intermediary, customer, counterparty, or transaction chain that is not itself sanctioned.
The sanctions risk effectively “passes through” the non-sanctioned party, creating hidden exposure for the institution even though the immediate transacting customer appears compliant.
In AML/CFT and sanctions compliance, this risk category is critical because sanctions evasion techniques increasingly rely on layered intermediaries, opaque ownership structures, trade networks, and payment chains that obscure the ultimate sanctioned nexus.
Explanation
Pass-through sanctions risk emerges when the sanctioned party is not the direct customer but is involved upstream or downstream in a transaction.
The financial institution may unknowingly process payments, settle trades, extend credit, or facilitate shipping arrangements that benefit or involve a sanctioned party.
This can occur even where traditional screening processes show no match because the exposure is embedded in the underlying beneficial ownership, supply chain, funding source, or ultimate use of goods or services.
This dynamic is common in cross-border transactions, correspondent banking, global trade finance, securities settlement, and fintech payment aggregation.
Opaque intermediaries, shell companies, new digital rails, and multi-layered routing pathways increase the probability that a sanctioned touchpoint is concealed within legitimate-looking flows.
From a regulatory standpoint, institutions are expected to identify and mitigate pass-through sanctions risk through enhanced due diligence, supply-chain visibility, beneficial-ownership analysis, and real-time monitoring of transactional behaviour.
Even unintentional facilitation can result in significant penalties, regulatory censure, or loss of correspondent relationships.
Pass-Through Sanctions Risk in AML/CFT and Sanctions Frameworks
Pass-through sanctions exposure intersects with multiple components of AML/CFT and sanctions compliance frameworks.
Key intersections include:
Beneficial ownership transparency and the identification of indirect control or economic benefit.
Reliance on intermediaries (brokers, PSPs, remitters, fintechs) who may lack sufficient sanctions controls.
Multi-tier supply chains in trade finance that obscure the ultimate buyer, seller, or shipment beneficiary.
Correspondent banking environments where originating banks may not have full visibility into downstream parties.
Securities and investment channels where funds can be routed through omnibus or custodial structures.
Institutions must adopt a risk-based approach that recognises that sanctions evasion often depends on the limitations of traditional screening, which typically focuses on direct customer matches versus indirect exposure.
Key Components of Pass-Through Sanctions Risk
Structural Drivers
Pass-through sanctions risk is usually driven by:
Complex ownership structures that obscure sanctioned ultimate beneficial owners (UBOs).
Intermediaries operating with insufficient sanctions controls or lax onboarding standards.
Payment routing through high-risk jurisdictions with limited regulatory oversight
Trade-based typologies that disguise the true origin, destination, or beneficiary of goods.
Use of omnibus or aggregated accounts that limit customer-level visibility.
Typical exposure points within financial institutions include:
Correspondent banking settlement flows.
Cross-border wire transfers with limited payment message transparency.
Trade finance activities involving freight forwarders, charterers, or third-party agents.
Fintech payment processors acting as intermediaries.
Securities clearing and settlement via omnibus structures.
Treasury and FX operations involving counterparties with opaque ownership.
Risks and Red Flags Associated With Pass-Through Sanctions
Pass-through sanctions risk can manifest silently within otherwise routine activity. Key red flags include:
Counterparties that resist providing detailed ownership or supply-chain documentation.
Transactions involving jurisdictions known for sanctions evasion or limited AML enforcement.
Payments routed through unusual correspondent banks or repeatedly re-routed through multiple intermediaries.
Sudden changes in trading partners, commodities, or shipping routes without economic justification.
Third-party payments where the payer or recipient has no clear relationship to the contractual parties.
Use of shell companies or recently incorporated entities with no physical presence.
Vessel behaviour anomalies such as AIS dark activity, mid-ocean transshipments, or frequent flag hopping.
These indicators often surface in trade finance, energy markets, shipping and maritime activities, and high-risk cross-border payments.
Common Methods & Techniques Used to Facilitate Pass-Through Sanctions Evasion
Sanctions evasion networks commonly rely on techniques that exploit visibility gaps in financial and trade systems:
Use of front companies or intermediaries to hide the sanctioned party’s involvement.
Transshipment through permissive jurisdictions to alter the apparent origin or destination of goods.
Third-party payment structures where unrelated entities settle invoices on behalf of sanctioned actors.
Layered corporate hierarchies involving nominee directors or chains of offshore entities.
Re-routing of digital asset flows through mixers or multiple wallets to obscure provenance.
Maritime obfuscation including ship-to-ship transfers, disabling AIS, and altering bill-of-lading information.
Over/under-invoicing in trade-based schemes to disguise value transfers benefiting sanctioned actors.
These techniques allow sanctioned entities to re-enter formal financial channels indirectly, often via seemingly legitimate entities.
Examples of Pass-Through Sanctions Risk Scenarios
Trade Finance: Hidden Beneficiary in a Letter of Credit
A bank issues a letter of credit for a customer importing industrial equipment.
The upstream manufacturer is a sanctioned entity, but the goods are invoiced and resold through a non-sanctioned distributor.
If the bank fails to review supply-chain documentation thoroughly, the sanctioned beneficiary remains concealed.
Correspondent Banking: Upstream Sanctioned Entity
A regional bank processes cross-border payments on behalf of a domestic fintech.
One of the fintech’s customers receives funds from an offshore company owned by a sanctioned individual.
Although the regional bank sees only the fintech as its customer, the sanctioned nexus exists upstream.
Digital Assets: Indirect Exposure through Wallet Hops
A customer receives cryptocurrency via several intermediary wallets.
One upstream wallet is linked to a sanctioned cybercrime group. Without attribution and clustering analytics, the pass-through risk is undetected.
Shipping and Maritime: Sanctioned Vessel in the Chain
A bank finances a trade involving crude oil shipments.
The shipment is transferred mid-ocean from a sanctioned vessel to a non-sanctioned vessel via ship-to-ship transfer.
The financing bank sees only the latter vessel.
Fintech Aggregation: High-Volume Payment Flows
A payment aggregator processes merchant settlements via a pooled account.
A sanctioned party funnels revenue through multiple micro-merchants.
The acquiring bank is exposed indirectly through the aggregator’s settlement account.
Impact on Financial Institutions
Pass-through sanctions risk can have severe strategic, operational, and regulatory consequences:
Regulatory penalties for facilitating transactions benefiting sanctioned actors, even unintentionally.
Reputational damage compromising customer trust and correspondent banking access.
Heightened compliance costs, including remediation, lookback projects, and system overhauls.
Increased reporting burdens through enhanced STR/SAR filings.
Legal liability and potential civil enforcement actions.
Downgrading by correspondent banks or global partners due to perceived sanctions exposure.
Institutions with poor sanctions-governance frameworks may face long-term systemic exposure, as pass-through risk often signals deeper structural weaknesses in monitoring.
Challenges in Detecting & Preventing Pass-Through Sanctions Exposure
Key challenges include:
Limited transparency into upstream or downstream parties in complex transactions.
Fragmented sanctions data across jurisdictions and agencies.
Inability to link behavioural patterns across payment chains or trade routes.
High false-positive rates when screening indirect relationships.
Reliance on intermediaries with insufficient sanctions controls.
Dynamic evasion techniques that evolve rapidly (for example, vessel deception technologies or mixer protocols).
Support intelligence-led sanctions monitoring incorporating behavioural, network, and entity-resolution analytics.
As sanctions regimes expand in scope and complexity, institutions must enhance their visibility across transactional chains and adopt proactive controls that detect indirect exposure routes.
