How should compliance teams approach crypto transaction monitoring when exchanges are operating before clear regulations exist?

← Back to all FAQ
By NHI Mgmt Group Editorial Team Updated September 23, 2026 Domain: Cyber Security

Compliance teams should treat transaction monitoring and source of funds checks as core controls, not optional extras. When regulation is still immature, banks and counterparties often become the de facto gatekeepers. The practical goal is to create enough visibility to flag suspicious activity, document customer risk, and support escalation to law enforcement without pretending that technical onboarding alone solves financial crime exposure.

Monitoring before regulation catches up

When exchanges move faster than the regulatory perimeter, compliance cannot wait for formal rulebooks to define the minimum bar. transaction monitoring should be treated as a risk control shaped by customer type, product design, geography, velocity, and counterparty exposure, not as a checkbox that only activates once supervisors publish detailed guidance. That means designing monitoring to surface suspicious patterns early, even where legal expectations are still forming.

The practical consequence is that firms often have to operate on a risk-based basis with incomplete external certainty. In that environment, banks, liquidity providers, and other counterparties may become the de facto control point, so monitoring has to support decisions about whether activity is explainable, documentable, and escalatable. A useful benchmark is whether the process can distinguish normal exchange behaviour from flows that deserve escalation, review, or restriction.

Because this subject sits at the intersection of financial crime control and market infrastructure, the monitoring logic should be explicit enough to defend later. That includes rule design, alert thresholds, customer risk scoring, and case notes that explain why a transaction was considered ordinary, unusual, or suspicious at the time it was reviewed.

How monitoring, source of funds checks, and escalation fit together

Transaction monitoring and source of funds checks work best as linked controls. Monitoring identifies patterns that merit attention, while source of funds review tests whether the funds path is consistent with the customer profile, declared activity, and expected economic purpose. For exchanges operating in a still-maturing environment, the objective is not perfect certainty, but a traceable decision trail that shows why the firm accepted, delayed, or escalated the activity.

That trail matters because the same transaction can look acceptable in isolation and problematic in context. Rapid movement across wallets, repeated high-value deposits followed by immediate withdrawals, or activity inconsistent with customer stated purpose may not prove criminality, but they do justify closer review and, where needed, enhanced due diligence or suspicious activity escalation. The control fails if it only detects obvious fraud after loss, rather than creating a reasoned basis for intervention earlier.

Good practice is therefore to pair monitoring with governance over alerts, review standards, and escalation thresholds. Compliance teams should be able to explain why a specific scenario was risk-rated, what evidence was required to clear it, and what conditions would trigger a freeze, exit, or report to law enforcement.

Risk and Threat Considerations

Without clear regulation, the main risk is not just non-compliance, but under-control. Exchanges can become attractive to illicit finance precisely because ambiguity allows weak onboarding, thin monitoring, and inconsistent escalation across counterparties and jurisdictions. If transaction surveillance is too permissive, suspicious flows can pass with little friction; if it is too blunt, legitimate customers are pushed into unnecessary friction or exit.

Failure mechanism: Weakly calibrated monitoring rules, poor customer risk segmentation, and incomplete source of funds evidence create blind spots that let suspicious activity blend into normal exchange traffic. In immature regulatory settings, that failure is often reinforced by inconsistent expectations across banks, payment providers, and law enforcement channels.

Impact: The exchange can miss suspicious activity, file poor-quality escalations, or be treated as a weak control point by counterparties and supervisors. Over time, that exposes the firm to de-risking, account restrictions, remediation costs, and greater exposure to financial crime abuse.

Standards & Framework Alignment

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.

NIST CSF 2.0 and CIS Controls v8 set the governance and control requirements practitioners need to meet.

FrameworkControl / ReferenceRelevance
NIST CSF 2.0GV.2 — Risk Management StrategySupports operating on a risk-based basis when formal regulation is immature.
Recommendation — Use a risk-based strategy to prioritise monitoring where regulatory detail is still evolving.
CIS Controls v88 — Audit Log ManagementTransaction monitoring depends on retained logs and reviewable evidence for investigations and escalation.
Recommendation — Retain and review logs so exchange activity can be investigated and escalated.

Practitioner Guidance

What to prioritise: Build monitoring around the transaction patterns that create the greatest AML exposure first, especially velocity, layering-like movement, and unexplained value transfer. If the exchange cannot explain why a transaction is ordinary, it should not be treated as cleared just because onboarding was completed.

What to verify: Check that alerts are tied to documented review criteria, that source of funds evidence is retained in a way investigators can use later, and that escalation outcomes are consistent across analysts. A control is not effective if two reviewers would make different decisions on the same fact pattern.

Practitioner takeaway: In immature regulatory markets, the safest stance is to run monitoring as a defensible financial crime control, not a future compliance placeholder, because the absence of a detailed rule set does not reduce the underlying exposure.
