How Weak AML Compliance Can Lead to Crypto Exchange Penalties

As the cryptocurrency industry evolves, policymakers the world over are starting to focus on the Anti-Money Laundering (AML) compliance of cryptocurrency exchanges. The almost unregulated environment of digital asset markets is either falling under financial surveillance models like banks and money service businesses or crypto exchanges are being charged as traditional financial institutions. Now we are just observing financially insolvent crypto exchanges who could barely keep up with AML compliance, facing unprecedented regulatory or civil penalties, being banned from operating, and suffering reputational damage.

This article will take a deep dive into how failure to comply with AML regulations puts crypto exchanges at risk of legal, financial, and operational penalties, and demonstrate that developing a robust AML compliance program is both an expectation from a regulatory perspective, and a part of good business practice. 

The Issue of AML Compliance in Cryptocurrency

In the most basic terms, AML compliance includes the federal, state, and local laws, regulations, and internal controls established to limit criminals disguising illicit criminal activity as legal activity. In this case, for cryptocurrency exchanges, it involves ensuring that their products or services do not facilitate money laundering, terrorist financing, or sanctions evasion.

During the unregulated scam like nature of crypto exchanges, was able to operate in a regulatory grey area. The decentralized and pseudonymous nature of cryptocurrencies and exchanges made it almost impossible for coins and exchanges to be held accountable through traditional AML compliance measures. Organizations that oversee regulations globally through the Financial Action Task Force (FATF) and national regulators like FinCEN, FCA, FINTRAC, and MAS have taken the lead in placing constraints on exchanges.

In present-day, exchanges must do the following:

• Verify customer identities (KYC).

• Monitor transactions for suspicious activity.

• Report either suspicious or large valued transactions.

• Maintain records demonstrating compliance.

• Develop risk-based policies and sanctions screening.

Not meeting compliance can result in millions in fines, stripping exchanges of their registration, criminals’ charges, and reputational harm.

Reasons Why Crypto Exchanges Are at High Risk for Compliance Failures to AML 

Crypto exchanges experience a unique set of AML risks as a function of their technological and operational nature: 

• Pseudonymity: Transactions are recorded on a blockchain and reveal wallet addresses, however, do not reveal real-world identities - much easier for bad actors to hide the origins of their funds. 

• Global Access: Remote access allows users from prohibited areas or high-risk jurisdictions to interface with the platform. 

• High Volume and Speed: Automated trades create a pressurized environment where millions of small transactions take place quickly and it is not possible to monitor all trades manually for risks, particularly for small amounts. 

• Mixers and Privacy Coins: Tools that anonymize transactions successfully hide illicit flows. 

• Rapid Change: New tokens, new DeFi products, and new cross-chain platforms introduce products and services faster than AML frameworks can react to them. 

Combined, these factors create an opportunity for weak AML controls to lead to unintentional facilitation of criminal activity and severe regulatory action.

Common Vulnerabilities Faced by AML Programs

1. Insufficient KYC Protocols

There is still a significant compliance gap regarding inadequate identity verification. Some exchanges have a history of letting customers trade or withdraw before they ever identify who the customer is. This is a direct violation of “Travel Rule” FATF guidance and national AML legislation.

Some failings include:

• Not identifying beneficial ownership.

• Poor vetting of Politically Exposed Persons (PEPs).

• Allowing false and incomplete identity submissions from customers.

• Not differentiating low-risk and high-risk customers.

In 2023, U.S. regulators unambiguously fined several exchanges for permitting anonymous accounts and high-value withdrawals without verifying a customer’s identity, highlighting that no KYC was no longer an option.

2. Weak Transaction Monitoring

AML compliance does not stop after onboarding. Continuous, ongoing transaction monitoring is essential. Nevertheless, many exchanges still rely on legacy systems and manual oversight that are not capable of detecting suspicious on-chain behaviour.

Weak transaction monitoring can manifest in the following ways:

• No real-time alert process.

• No vetting of transaction layering or structuring.

• No monitoring of links to darknet markets, ransomware wallets, or mixers.

• No monitoring of cross-chain behaviour.

In today's environment, compliance heavily relies on technology: automated solutions with analysis of on-chain behaviour via blockchain analytics and machine learning to detect behavioural patterns.

3. Ineffective Sanctions Screening

Sanction breaches represent one of the most expensive compliance failures. Exchanges are required to screen users, counterparties, and wallets against the sanctions list (OFAC, UN, EU, etc.).

Weak points include, but are not limited to:

• Failing to provide real-time updates of the sanction list.

• Not screening wallet addresses active with a sanctioned entity.

• Poor geographic controls.

For example, in 2024, several exchanges faced penalties for permitting wallets tied to sanctioned Russian and North Korean entities to transact.

4. Governance and Oversight Failures

Even the best compliance tools fail without proper governance. Many exchanges regard AML as an afterthought, resulting in the absence of:

• A dedicated compliance officer or team.

• Board oversight.

• The absence of independent audits or risk assessments.

• Inadequately trained staff responsible for their AML responsibilities.

• Regulators view such issues as a systemic neglect rather than isolated negligence. 

5. Record-Keeping Failures and Reporting Failures

An AML program should provide documentation of due diligence. We have seen exchanges being fined for failing the Suspicious Activity Reports (SARs) filing requirement, failing to maintain transaction logs, or to retain the KYC documents.

Regulators often point to a lack of documentation as evidence of a “culture of non-compliance.”

Real-World Case Studies: The Financial Impact of Weak AML Compliance

Case Study #1 - OKX - $500 Million Fine - (2025)

The U.S. Department of Justice issued a fine to OKX of more than $500 million for failing to comply with AML and sanctions requirements, on a systemic level. It was established that OKX was permissive and allowed the processing of over $5 billion in suspicious transaction activity, in addition to allowing users located in the U.S. to access the trading platform with false identification.

What went wrong?

- They advised customers to provide false country of residence information.

- They did not screen or report on sanctions.

- Transaction monitoring was lax for multiple years.

The case served as a global warning to other exchanges to elevate and enhance their compliance framework.

Case Study #2 - KuCoin - $19.6 Million Fine (2025, Canada)

Canada's FINTRAC issued a C$20 million fine against KuCoin's parent company Peken Global Limited, for failure to register as a money service business and failure to fulfil reporting obligations.

What went wrong:

- They did not register under Canada AML law.

- They did not submit reports on large virtual currency transactions.

- KYC records were erroneous.

This was the largest penalty in Canadian history imposed for AML compliance failure and demonstrates the willingness of regulators to act when an exchange does not meet registration requirements.

Consequences of Insufficient AML Compliance

• Financial Fines: Fines can reach hundreds of millions, and for smaller exchanges can even be crippling. 

• Criminal Liability: Executives risk being prosecuted for intentional non-compliance.

• Loss of License: Regulators can suspend or revoke the right to operate.

• Operational Disruption: Banking partners may sever relationships, freezing the exchange's operations in fiat. 

• Reputational Risk: Customers will lose trust in your platform and withdraw their funds in masses.

• Regulatory Monitoring: An exchange may be subject to costly monitoring by third parties.

Insufficient AML compliance is not a failure to fill out “paperwork.” It is a risk to your existence.

Building a Strong AML Framework for Crypto Exchanges

1. Strong Governance

• Hire a chief compliance officer (CCO) who reports directly to the board.

• Have regular risk assessments by geography, type of customer, and type of assets.

• Train all staff on AML obligations and red flag indicators.

• Encourage a compliance culture from the top down.

2. Strong KYC / KYB

• Collect full identity verification for all users before allowing them to trade.

• Verify beneficial ownership for corporate accounts.

• Sanction, PEP, and adverse media screening for all customers.

• Enhanced due diligence (EDD) for users that are considered high risk, including unhosted wallet users and cross-border accounts.

3. Enhanced Transaction Monitoring

• Utilize tools that provide real-time blockchain analytics and AI-based monitoring.

• Identify suspicious activity (e.g., fast layering, round-tripping, mixer usage)

• Assign "risk scores" to wallets and bar access for high-risk addresses.

• Promptly investigate alerts, and if necessary, file Suspicious Transaction Reports (STRs). 

4. Sanctions Compliance

• Continuously monitor international sanctions lists.

• Screen wallets and addresses for all incoming and outgoing transactions.

• Implement geofencing articulations to restrict access from jurisdictions subject to sanctions. 

• Keep track of all sanction’s checks carried out for audit preparation.

5. Reporting and Record Keeping

• File reports (STRs, large transaction reports) in the timeliness required by regulations. 

• Maintain records of transactions, KYC, and investigation notes for a minimum of 5–7 years. 

• Use tamper-proof databases to preserve evidentiary audit trails. 

6. Independent Audits and Continuous Improvement

• Engage annual independent audits on AML programs. 

• Obtain benchmarks to FATF and local VASP regulatory standards. 

• Consistently revisit compliance programs in relation to evolving regulatory standards. 

• Encourage interactions with analytics vendors as the risk evolves.

As the crypto landscape continues to transform itself, AML compliance for crypto exchanges is now considered less of an administrative checklist and more of a core component of business legitimacy and sustainability. Just within the last few years, regulators have imposed historic fines on exchanges that demonstrate a lack of AML compliance, such as OKX and KuCoin. 

Weak AML compliance could dismantle a crypto exchange faster than any bear market. Conversely, exchanges that invest in robust AML compliance programs establish trust, sustained value, and resilience to regulatory scrutiny.

While regulatory scrutiny has been in a constant state of increase internationally, every individual crypto exchange must begin to ask:

"Are we AML-compliant or are we simply a penalty waiting to happen?"
