Sanctions Knowledge Hub
Your complete guide to global sanctions — EU, OFAC, UN, HM Treasury, SECO, and more. Built for AML, KYC, CDD, EDD and sanctions screening professionals across the world.
1. What Are Sanctions?
Sanctions are legally binding restrictions imposed by governments or international bodies to prevent terrorism, money laundering, human rights abuses, corruption, nuclear proliferation and threats to international security. Financial institutions, fintechs, VASPs, PSPs, and corporates must screen customers, payments, and transactions against sanctions lists at all times.
2. Why Sanctions Matter in AML/KYC
- They prevent criminals, terrorists and hostile states from accessing financial systems.
- Failure leads to massive enforcement actions (HSBC, BNP, Standard Chartered, Westpac, ING).
- Sanctions are strict liability — intent does not matter.
- Real-time screening is required during onboarding and every transaction.
3. Types of Sanctions
Financial Sanctions
Freezing of assets, blocking funds, prohibiting economic resources. Core obligation for banks and fintechs.
Trade & Export Sanctions
Restrict export/import of goods, technology, dual-use items, and military equipment.
Sectoral Sanctions (SSI)
Partial restrictions targeted at specific industries (energy, banking, defense).
Travel / Visa Bans
Prevents sanctioned individuals from entering or moving within countries.
4. Who Issues Sanctions?
- European Union (EU) – Restrictive Measures (Official Journal)
- United States: OFAC – SDN, SSI, Non-SDN Lists
- United Nations (UN) – Security Council Sanctions
- United Kingdom (HMT) – OFSI Consolidated List
- Switzerland (SECO) – Sanctions based on UN/EU
- Canada, Australia, Singapore – Independent list regimes
5. EU vs OFAC vs UN: Key Differences
| Regime | Scope | Legal Effect |
|---|---|---|
| EU (Restrictive Measures) | 28 Member States, OJ Publications | Directly Binding |
| OFAC (USA) | Global — USD exposure triggers liability | Strict Liability (no intent needed) |
| UN Sanctions | Global Framework via Security Council | Must be implemented locally |
6. Who Gets Sanctioned?
Individuals
Terrorists, warlords, political elites, traffickers, oligarchs.
Companies & Banks
State-owned entities, shell firms, military companies.
Countries / Regimes
Russia, Iran, DPRK, Syria, Myanmar, etc.
Vessels & Aircraft
Used to evade oil embargoes or smuggle arms.
7. Sanctions Screening Workflow (End-to-End View)
Every bank, fintech, PSP or VASP should be able to sketch their sanctions screening process in a simple flow. Below is a clean, practical model used in many mature AML programmes:
8. What Data Must Be Screened?
Sanctions compliance is not only about names. A strong programme screens multiple data elements:
Customer Data
- Full name, aliases, previous names
- Date of birth, place of birth
- Addresses, nationality, residency
- Company name, registration number
Transaction Data
- Sender & beneficiary names
- Account numbers / IBAN / wallet IDs
- Payment messages (fields 50, 59, 70, etc.)
- Remittance information / free text fields
Counterparty & Ownership
- Shareholders & UBOs
- Directors & controllers
- Group structures and linked entities
- Vessels, aircraft, trading names
9. Sanctions Screening – Best Practices for Compliance Teams
Use Authoritative & Updated Lists
EU, OFAC, UN, UK, SECO and any local list. Refresh daily or more frequently when geopolitics is volatile.
Tune Matching Logic Carefully
Avoid both extremes: too strict (miss matches) and too fuzzy (too many false positives). Test on real data.
Centralised Escalation Rules
Clear criteria for which hits can be closed by Level 1 and which must go to Level 2 / MLRO.
Document Every Decision
Audit trail is everything. Regulators often criticise decisions that were not properly recorded.
10. How to Handle a Sanctions Hit (Analyst Flow)
A strong analyst flow keeps customers safe, protects the bank and gives regulators confidence in your process:
1. System Alert
Alert generated from real-time or batch screening (customer or payment).
2. Initial Triage
Check spelling, geography, DOB, citizenship, role / sector, list type.
3. Decide Match vs No Match
If clearly no match, close with rationale. If unclear or likely match, escalate.
4. MLRO / Sanctions Officer
Final decision: block, reject, freeze, maintain relationship, or exit client.
11. Common Sanctions Screening Pitfalls
Ignoring UBOs & Ownership
Screening only direct customers but not the shareholders behind them (50%+ or control).
Not Updating Lists in Time
Delayed list updates mean you could process payments for a newly added sanctioned party.
Over-Reliance on Vendors
“Vendor says we’re compliant” is not a defence. Institutions remain ultimately responsible.
Poor Alert Documentation
Regulators often criticise “no match” closures without proper written rationale.
12. Sanctions Red Flags for KYC & Transaction Monitoring
- Customer insists on using complex payment chains without a clear commercial reason.
- Use of shell or front companies in known transshipment or sanctions evasion hubs.
- Payments referencing sanctioned countries, locations, ports or oil / defence terms.
- Frequent small transfers just below internal monitoring thresholds.
- Routing of USD payments through specific correspondent banks with higher risk profile.
- Customer unwilling to provide full ownership or end-user information.
- Trade documents inconsistent with shipping routes, invoices or bills of lading.
- Use of generic descriptions like “services” or “consulting” for large cross-border wires.
13. Common Sanctions Evasion Techniques
Sanctions evaders are creative. Your job is to recognise their patterns even when names do not match exactly.
Front & Shell Companies
Sanctioned owners hide behind layers of “clean” entities in low-transparency jurisdictions.
Ownership Splitting
Reducing individual shareholdings below 50% to avoid list-based control rules, while still retaining de facto control.
Transshipment & Re-Routing
Routing goods via third countries to disguise the real origin or destination of sanctioned cargo.
Ship-to-Ship Transfers
Vessels turn off AIS, meet offshore and move oil or goods to a non-sanctioned vessel.
Name Variants & Spelling Tricks
Changing order of names, transliteration tricks, or using nicknames to bypass basic screening.
Use of Crypto & Mixers
Sending funds via exchanges, P2P platforms or privacy tools to obscure the sanctioned origin.

15. Sanctions Typologies (20+ Real-World Patterns)
These typologies are observed across global investigations, regulatory reports, OFAC advisories and EU restrictive measures. Use them to train KYC analysts, EDD teams and transaction monitoring specialists.
1. Oil Sanctions Evasion
Use of disguised shipping routes, AIS gaps, falsified certificates, and offshore STS transfers.

Export of items usable for both civilian and military purposes disguised via trading companies.
