INTERPOL and crypto — developments in international enforcement

Introduction

The rapid expansion of cryptocurrency markets has transformed the landscape of international financial crime. Digital assets now feature in investigations involving fraud, corruption, money laundering, sanctions evasion, ransomware, cyber-attacks, and organised crime.

As Gherson Solicitors have highlighted across a series of previous articles, INTERPOL has increasingly positioned itself at the centre of global efforts to address crypto-related offending. From intelligence sharing and asset tracing to coordinated arrest operations, the organisation’s tools are evolving to meet the challenges posed by decentralised finance and digital anonymity.

This article summarises Gherson’s previous analysis of how INTERPOL is adapting to the crypto era, the mechanisms now being deployed, and the implications for individuals, businesses, and financial institutions.

The growth of crypto-related crime

Cryptocurrencies were once seen as niche financial instruments, but they now play a significant role in global markets. Alongside legitimate use, they have also become embedded in cross-border criminal activity.

Gherson’s previous articles note that digital assets present unique challenges for investigators, including:

• Pseudonymous transactions;
• Cross-border wallet transfers;
• Rapid movement of funds;
• Decentralised exchanges;
• Lack of central authority; and
• Complex tracing requirements.

These features make cryptocurrency attractive for both sophisticated organised networks and opportunistic fraudsters.

As a result, law enforcement agencies have increasingly relied on international cooperation — and this is where INTERPOL’s role has expanded.

INTERPOL’s strategic shift toward financial and cyber crime

Historically associated with fugitive tracking and violent crime alerts, INTERPOL has in recent years focused heavily on financial crime infrastructure.

Gherson’s previous commentary highlights that crypto investigations now sit at the intersection of:

• Cybercrime;
• Fraud;
• Organised crime;
• Asset recovery; and
• Sanctions enforcement.

This shift has driven the organisation to develop new operational models and investigative tools.

Coordinated global operations

One of the clearest demonstrations of INTERPOL’s evolving role has been the expansion of coordinated international enforcement campaigns.

Operation HAECHI

Gherson’s previous analysis highlights INTERPOL’s multi-phase Operation HAECHI programme, which targets online fraud networks operating across borders and frequently using cryptocurrency.

Recent phases of the operation have resulted in:

• Thousands of arrests;
• Seizure of hundreds of millions in assets;
• Disruption of fraud call-centre networks; and
• Identification of crypto wallets used in scams.

These operations demonstrate that crypto investigations increasingly depend on rapid international coordination rather than purely domestic enforcement.

Asset tracing and seizure in the crypto era

From cash to wallets

Traditional asset tracing focused on bank accounts, property, and corporate holdings. Cryptocurrency investigations, however, require a different skill set.

Gherson’s previous commentary stresses that digital asset tracing involves:

• Blockchain analytics;
• Transaction clustering;
• Wallet attribution;
• Exchange cooperation; and
• Cross-jurisdiction freezing requests.

INTERPOL has therefore expanded partnerships with national cyber units and financial intelligence bodies.

The emergence of the Silver Notice

A major development discussed in Gherson’s publications is the introduction of INTERPOL’s Silver Notice.

Purpose of the Silver Notice

The Silver Notice allows member states to request assistance in identifying, tracing, and monitoring assets linked to criminal activity.

This includes:

• Real estate;
• Vehicles;
• Corporate holdings;
• Bank accounts; and
• Digital assets.

The notice represents a significant shift toward financial investigation tools rather than purely fugitive tracking.

Crypto-specific impact

Gherson’s previous analysis highlights that Silver Notices are particularly relevant to cryptocurrency investigations because they allow states to:

• Locate wallets tied to suspects;
• Track asset movements internationally;
• Request monitoring by other jurisdictions; and
• Facilitate eventual recovery proceedings.

In crypto-related fraud cases, this mechanism may prove as significant as Red Notices have been in extradition matters.

Intelligence sharing through purple notices

Another tool increasingly relevant to crypto enforcement is the Purple Notice.

Function of Purple Notices

Purple Notices enable countries to share information about criminal methods, technologies, or concealment techniques.

Gherson has previously noted that these notices have been used in the crypto context to:

• Warn about new phishing and wallet-draining schemes;
• Share intelligence on ransomware payment mechanisms;
• Circulate information about laundering techniques; and
• Identify cross-border scam infrastructure.

This function is particularly important in the crypto sphere, where new fraud techniques emerge rapidly.

INTERPOL’s cyber-focused institutional development

Dedicated crypto and cyber expertise

Gherson’s previous commentary indicates that INTERPOL has been investing in specialist cybercrime units and digital investigation capabilities.

This includes:

• Training programmes for member states;
• Operational intelligence hubs;
• Technical cooperation with blockchain analytics providers; and
• Development of digital forensic expertise.

Such developments reflect recognition that future international policing will be heavily technology-driven.

Why crypto requires international coordination

Cryptocurrency investigations often involve multiple jurisdictions simultaneously. For example:

• Victims in one country;
• Suspects located in another;
• Wallets registered through an exchange elsewhere; and
• Servers hosted in a fourth jurisdiction.

Gherson’s previous writings emphasise that this fragmentation makes INTERPOL uniquely suited to act as a coordinating platform. Without such cooperation, investigations risk stalling at national borders.

Legal and human rights considerations

While INTERPOL’s growing involvement in crypto enforcement strengthens international policing, Gherson’s analysis also highlights legal risks.

Risk of over-criminalisation

Some crypto-related disputes arise from commercial or regulatory disagreements rather than clear criminal conduct. Where states criminalise activities differently — for example, exchange regulation breaches — international alerts may be issued in circumstances that are legally contentious.

Due process concerns

Gherson has previously consistently stresses that individuals may face:

• Asset freezes;
• Travel restrictions;
• Reputational harm; and
• Extradition risk

– even before allegations are fully tested in court.

This makes early legal advice crucial in crypto-related INTERPOL matters.

The role of Red Notices in crypto cases

Although financial investigation tools are expanding, Red Notices remain central where suspects are alleged to have committed crypto-related offences.

Gherson has previously noted that such cases may involve:

• Large-scale fraud schemes;
• Exchange collapses;
• Investment platform allegations;
• Ransomware networks; and
• Sanctions-related crypto transactions.

 

In such cases, INTERPOL mechanisms may combine:

• Fugitive tracking;
• Intelligence sharing; and
• Asset tracing

into a single enforcement framework.

The future of INTERPOL and cryptocurrency

Gherson’s previous publicly available commentary suggests several trends likely to shape the next phase of development.

1. Increased use of asset-focused tools

The Silver Notice signals a broader shift toward financial enforcement and asset recovery –particularly relevant in crypto cases, where identifying and freezing funds may be more important than immediate arrest.

2. Integration of technology into policing

Blockchain analysis and cyber-intelligence tools are becoming central to investigations. INTERPOL’s growing technical capabilities suggest this trend will accelerate.

3. Expansion of multi-state enforcement operations

Operations such as HAECHI demonstrate that global policing will increasingly involve coordinated international campaigns rather than isolated national actions.

Practical implications for individuals and businesses

Gherson’s previous articles repeatedly stress that crypto-related INTERPOL activity can affect not only suspects but also:

• Business partners;
• Company directors;
• Investors;
• Compliance officers; and
• Exchange users.

 

Consequences may include:

• Account closures;
• Frozen assets;
• Reputational issues;
• Immigration complications; and
• Enhanced due-diligence scrutiny.

Because digital assets can move rapidly, early legal intervention is often critical.

The importance of strategic legal advice

Crypto-related INTERPOL matters typically require expertise across multiple areas of law, including:

• Criminal defence;
• Extradition;
• Sanctions;
• Financial regulation;
• Asset recovery; and
• Immigration

Gherson’s previous commentary emphasises that effective defence strategies often involve parallel legal action in several jurisdictions.

Conclusion

Cryptocurrency has reshaped the nature of international financial crime, and INTERPOL’s role has evolved accordingly. Through coordinated operations, new asset-tracking tools, intelligence-sharing mechanisms, and cyber-focused institutional developments, the organisation is positioning itself at the centre of global crypto enforcement.

As Gherson’s previous analysis demonstrates, these developments carry significant implications not only for law enforcement but also for individuals, investors, and businesses operating in an increasingly digitised financial environment.

Understanding how INTERPOL operates in the crypto sphere is therefore critical for anyone exposed to cross-border financial risk.
