At what transaction size does KYC become mandatory?

In the US, cash transactions over $10,000 trigger a mandatory Currency Transaction Report (CTR) under the Bank Secrecy Act. But KYC as a process should run on every transaction — enhanced due diligence kicks in around $25,000 or whenever behavior raises red flags regardless of size. The $10K number is the reporting threshold, not the "start caring" threshold.

Do I have to file a SAR if I am unsure?

Yes — the Suspicious Activity Report is intentionally designed for "reasonable suspicion", not certainty. If a pattern feels wrong (structured payments under $10K, reluctance to provide ID, urgency combined with overpayment), file it. You are protected from civil liability for SARs filed in good faith. The regulatory risk of not filing is far higher than filing one that turns out benign.

How long do I need to keep KYC records?

Minimum 5 years after the business relationship ends, under both the US Bank Secrecy Act and EU AML Directives. Keep investigation-related records (anything linked to a filed SAR) indefinitely. Store records in a format that is searchable — regulators will ask for specific transactions by date, counterparty, and amount during an audit.

Can I rely on a third-party KYC provider instead of doing it myself?

You can use providers like Jumio, Onfido, or Persona to handle the mechanics of ID verification and sanctions screening, but legal liability stays with you as the dealer. The regulator does not care that a vendor missed a forged passport — your license is still the one on the line. Use automation for speed, but own the policy and the escalation decisions.

Does KYC apply to peer-to-peer dealer-to-dealer transactions?

Yes. "Dealer" status does not exempt anyone from KYC — it typically raises the bar. When selling to another dealer, collect their business registration, beneficial ownership, and at least 2 trade references. Treat other dealers as higher-risk for structuring because they move volume. A clean dealer-to-dealer file is also your best defense if one of their downstream customers turns out to be a problem.

Why KYC Matters in Watch Trading

In 2025, the Financial Action Task Force (FATF) further strengthened its guidance on high-value goods dealers, explicitly naming luxury watches alongside jewelry and art. For watch dealers operating in the US, EU, or UK, robust Know Your Customer (KYC) procedures are no longer optional — they're a legal requirement that carries penalties of up to $500,000 per violation under the Bank Secrecy Act. Beyond compliance, effective KYC protects your reputation, filters out fraudulent actors, and builds the kind of trust that turns one-time buyers into repeat clients.

Regulatory Alert

As of 2026, US dealers must file CTRs (Currency Transaction Reports) for cash transactions over $10,000 and SARs (Suspicious Activity Reports) for any transaction that raises red flags — regardless of amount. The EU's latest AML package has further tightened requirements for luxury goods dealers.

Essential KYC Documentation

The Verification Process

Document Collection — Request clear, high-resolution copies. Verify authenticity by checking security features, expiration dates, and cross-referencing details across multiple documents.
Identity Verification — Use a third-party identity verification service (like Jumio or Onfido) for high-value transactions. For deals over $25K, conduct a live video call to match face to ID.
Enhanced Due Diligence — For transactions over $10,000 or high-risk profiles: verify source of wealth, run sanctions screening (OFAC, EU, UN lists), and document everything.
Ongoing Monitoring — Don't treat KYC as a one-time event. Re-verify documents annually for repeat clients and monitor for unusual pattern changes.

Red Flags: When to Walk Away

KYC Red Flag Matrix

Category	Red Flag	Risk Level	Action
Documentation	Blurry, altered, or expired documents	High	Decline until valid docs provided
Documentation	Mismatched information across documents	Critical	File SAR, decline transaction
Behavior	Unusual urgency or pressure to close fast	Medium	Slow down, verify thoroughly
Behavior	Insistence on cash-only payment	High	Require bank transfer for amounts >$5K
Behavior	Reluctance to provide ID or meet in person	High	Decline transaction
Transaction	Structuring payments to stay under $10K	Critical	File SAR immediately
Transaction	Frequent high-value trades without clear business purpose	High	Enhanced due diligence required

Pro Tip

Create a standardized KYC checklist that your team follows for every transaction. Consistency protects you legally — regulators look favorably on documented, repeatable processes.

Record Keeping Requirements

Proper record keeping isn't just good practice — it's the law. Under the Bank Secrecy Act and EU Anti-Money Laundering Directives, you must retain all customer identification documents, transaction records, communication logs, due diligence findings, and monitoring notes for a minimum of 5 years after the business relationship ends. Investigation documents should be preserved indefinitely.

Technology Solutions

Modern KYC platforms dramatically reduce friction while improving compliance. Automated identity verification can process and validate an ID in under 30 seconds. Document authentication services detect forgeries with 99.5% accuracy. Real-time sanctions screening runs against global databases instantly. And biometric verification adds an additional layer of certainty for high-value transactions.

Mazalgo's integrated KYC tools automate document collection, risk assessment, and compliance reporting — so you can focus on trading, not paperwork.

International Considerations

Cross-border transactions introduce additional complexity. EU's 6th Anti-Money Laundering Directive (6AMLD) imposes stricter beneficial ownership requirements. Switzerland's FINMA guidelines apply to dealers handling more than CHF 100,000 annually. Hong Kong and Singapore have their own reporting thresholds. Always consult legal counsel when dealing with unfamiliar jurisdictions, and be especially careful with sanctioned countries — violations carry severe criminal penalties.
