You can't apply your legacy AML policy to crypto transactions and expect it to hold up under regulatory scrutiny. The anonymity and decentralization of digital currencies create monitoring blind spots that traditional customer due diligence and transaction surveillance weren't built to catch.
This template provides a framework for documenting how your institution handles AML obligations when customers interact with digital currencies. It's designed to address the specific risks crypto introduces while maintaining compliance with the Bank Secrecy Act and Anti-Money Laundering Directive requirements.
Purpose of the Template
Use this policy to define your organization's approach to AML compliance when customers:
- Send or receive funds from cryptocurrency exchanges
- Convert fiat currency to digital assets or vice versa
- Use accounts that show transaction patterns consistent with crypto trading
- Operate businesses that accept cryptocurrency as payment
The template covers customer due diligence, transaction monitoring thresholds, and enhanced screening procedures specific to crypto exposure. It supplements, not replaces, your core AML program.
Prerequisites
Before customizing this template, ensure you have:
- A designated AML compliance officer with authority to approve policy changes
- Transaction monitoring systems capable of flagging crypto-related activity
- Access to watchlist screening tools that include crypto exchange sanctions lists
- Documentation of your institution's risk appetite for crypto-exposed customers
- Training materials ready for staff who will apply these procedures
You'll also need to know which digital currency activities your institution permits. If you prohibit all crypto transactions, this policy becomes a detection-and-exit protocol rather than an ongoing monitoring framework.
The Policy Template
CRYPTOCURRENCY TRANSACTION AML POLICY
1. SCOPE
This policy applies to all customer accounts where transaction activity
indicates interaction with digital currency platforms, including:
- Direct transfers to/from known cryptocurrency exchanges
- Peer-to-peer payments with crypto-related memo fields
- Cash deposits or withdrawals consistent with crypto arbitrage patterns
2. RISK CLASSIFICATION
Accounts showing crypto activity receive Enhanced Due Diligence status and
elevated transaction monitoring.
Automatic triggers:
- Monthly aggregate transfers >$25,000 to/from crypto exchanges
- Transactions involving exchanges domiciled in high-risk jurisdictions
- Customers self-identifying as crypto businesses during onboarding
3. ENHANCED CUSTOMER DUE DILIGENCE
For crypto-exposed accounts, obtain and document:
- Source of funds verification (employment records, business financials,
investment account statements)
- Purpose of cryptocurrency use (investment, business operations,
cross-border payments)
- Names and jurisdictions of all crypto platforms customer uses
- Expected monthly transaction volume and frequency
Refresh this information every 12 months or when activity patterns change
by >50%.
4. TRANSACTION MONITORING PARAMETERS
Apply these thresholds to crypto-exposed accounts:
Velocity alerts:
- >3 transactions to crypto platforms in 24 hours
- >$10,000 daily aggregate to exchanges (vs. $25,000 for standard accounts)
Pattern alerts:
- Rapid in-and-out (funds in, immediate transfer to exchange, return within
72 hours)
- Structuring: Multiple sub-$10,000 transactions to same exchange within
5 business days
- Round-dollar amounts suggesting possible [Structuring (Smurfing)](/glossary/structuring-smurfing)
Geographic alerts:
- Transactions involving exchanges in jurisdictions not matching customer's
stated platforms
5. PROHIBITED TRANSACTION TYPES
Immediately file [Suspicious Activity Report](/glossary/suspicious-activity-report) (SAR) and consider account
closure for:
- Transfers to/from exchanges on OFAC sanctions lists
- Transactions where customer cannot explain source of incoming crypto-sale
proceeds
- Accounts receiving funds from multiple third parties, then consolidating
to crypto platform (possible [money mule](/glossary/money-mule) activity)
6. WATCHLIST SCREENING ENHANCEMENTS
For crypto-exposed customers, screen against:
- Standard [Politically Exposed Person](/glossary/politically-exposed-person) (PEP) and sanctions lists
- Crypto exchange enforcement actions (FinCEN consent orders, exchange
shutdowns)
- Blockchain analysis provider risk scores (if available)
Re-screen crypto customers quarterly vs. annually for standard accounts.
7. SAR FILING REQUIREMENTS
File SAR within 30 days when:
- Customer refuses to provide crypto platform documentation during EDD
- Transaction patterns suggest use of mixers or tumblers (frequent small
transfers with no clear business purpose)
- Incoming wires reference ICOs or token sales from unregistered issuers
- Customer's crypto activity inconsistent with stated occupation/business
Include blockchain addresses and exchange names in SAR narrative when known.
8. TRAINING REQUIREMENTS
All customer-facing staff complete crypto AML training covering:
- Common cryptocurrency transaction patterns
- How to identify exchange names in wire transfer details
- When to escalate to compliance officer
- Privacy considerations (don't discuss customer's crypto activity with
unauthorized parties)
Refresh training when regulations change or after any crypto-related SAR
filing.
9. POLICY REVIEW CYCLE
Compliance officer reviews this policy every 6 months and after:
- New AML Directive provisions affecting digital currencies
- FinCEN guidance updates on cryptocurrency
- Internal audit findings related to crypto monitoring
Customization Tips
Adjust the dollar thresholds in Section 4 based on your customer base. A fintech serving retail investors might use lower triggers; a commercial bank might set higher thresholds but add business-type filters.
Modify the prohibited transaction list (Section 5) to reflect your institution's risk tolerance. Some banks prohibit all crypto exchange transactions; others allow them with enhanced monitoring. Document your rationale either way.
Add jurisdiction-specific requirements if you operate in multiple regions. The European Union's Fifth Anti-Money Laundering Directive, introduced in 2020, imposed different crypto platform registration requirements than US regulations. Your policy should reference the specific directives that apply to your licenses.
Define "known cryptocurrency exchanges" in an appendix. Your transaction monitoring system needs a list of exchange names, wire beneficiaries, and common memo field text to trigger the policy. Update this list quarterly as new platforms launch.
Specify your blockchain analysis approach if you use one. Some institutions subscribe to services that trace crypto wallet addresses; others rely solely on fiat transaction monitoring. Your policy should clarify which signals you act on.
Validation Steps
After implementing this policy:
Test your monitoring rules by running historical transactions through the new thresholds. You should see alerts on accounts you already know have crypto exposure. If you get zero hits, your parameters are too loose or your exchange name list is incomplete.
Conduct a tabletop exercise where compliance staff walk through a scenario: "Customer receives $50,000 wire from Coinbase, immediately withdraws $48,000 cash in four transactions over three days." Can they identify which policy sections apply and what actions to take?
Review your last 90 days of SARs. Would any crypto-related filings have been caught faster under this policy? If you filed SARs on crypto activity that this policy wouldn't have flagged, your thresholds need adjustment.
Verify training completion for all staff who interact with customers. They should be able to name at least three crypto exchanges and describe one red flag pattern without consulting the policy document.
Schedule your first policy review before you implement. The regulatory landscape for digital currencies changes faster than traditional AML rules. The European Union introduced the Fourth Anti-Money Laundering Directive in 2017 and the Fifth in 2020; your policy review cycle needs to match that pace.
Don't wait for a regulatory exam to discover your AML framework has a crypto blind spot. Capital One's $390 million penalty for Bank Secrecy Act violations came after the bank failed to report $16 billion in transactions despite regulator warnings. The cost of adapting your policy now is a fraction of the enforcement risk you carry without it.
