Stablecoin

Simply put

A stablecoin is a type of cryptocurrency designed to hold a steady value by tying it to a real-world reference asset, most commonly a fiat currency such as the US dollar. Unlike more volatile cryptocurrencies, its price is intended to stay relatively stable. This stability is what generally distinguishes stablecoins from other digital assets.

Formal definition

A stablecoin is a cryptographic digital token that aims to maintain a stable value relative to a specified reference asset, or to a pool or basket of assets, typically a fiat currency such as the US dollar. The stability mechanism links the token's value to the reference asset (commonly described as a peg), which differentiates stablecoins from cryptocurrencies whose values are not tied to an external reference. Note that the descriptions in this evidence are general and definitional in nature; the specific design, backing, and stabilization methods vary by issuer, and the regulatory treatment of stablecoins differs across jurisdictions and should be confirmed against the applicable regime.

Why it matters

Stablecoins occupy a distinctive position in the virtual asset landscape because their design goal of holding a steady value relative to a reference asset, most commonly a fiat currency such as the US dollar, makes them attractive for functions that more volatile cryptocurrencies serve less readily, such as transferring value or moving between crypto and fiat. For AML and financial crime compliance professionals, this same characteristic raises questions about how stablecoins may be used to move funds, and why obliged entities that interact with them need to understand the specific design, backing, and stabilization mechanism of any given token rather than treating all stablecoins as identical.

The regulatory treatment of stablecoins is not uniform. As the evidence indicates, the specific design, backing, and stabilization methods vary by issuer, and regulatory treatment differs across jurisdictions and should be confirmed against the applicable regime. Compliance teams should therefore avoid assuming that a single global rule governs stablecoins, and should instead identify which framework applies to a particular activity, issuer, or counterparty. A token's classification, the obligations attaching to its issuance or exchange, and the supervisory body responsible can all diverge depending on the jurisdiction in question.

Because a stablecoin's stated peg is a design intention rather than a guarantee, professionals should treat the term as describing an aim to maintain stable value relative to a reference asset, not an assurance that value will always hold. Understanding this distinction is important when assessing the nature of a stablecoin arrangement, the reference asset it is tied to, and how any of these features bear on risk assessment and the applicable regulatory obligations.

Who it's relevant to

Compliance officers at virtual asset service providers
Professionals overseeing AML programs at entities that issue, exchange, or handle stablecoins need to understand that design, backing, and stabilization methods vary by issuer, and that regulatory treatment differs across jurisdictions. Obligations should be confirmed against the applicable regime rather than assumed to be uniform.
Financial intelligence analysts and investigators
Analysts examining flows involving digital assets should recognize how stablecoins differ from more volatile cryptocurrencies by aiming to maintain a stable value relative to a reference asset. Understanding a token's design and reference asset supports more accurate assessment of how value may be moved.
Legal and risk professionals
Those advising on virtual asset activity should note that the classification and regulatory treatment of stablecoins is not settled globally and diverges across jurisdictions. Determining which framework applies to a specific issuer, token, or activity is essential, and specific regulatory positions should be verified against the relevant regime.
Compliance staff at traditional financial institutions
Banks and other obliged entities that encounter stablecoin-related activity through their customers or counterparties benefit from understanding that a stablecoin's peg is a design intention, not a guarantee, and that the backing and stabilization approach varies by issuer when assessing exposure and risk.

Inside Stablecoin

Stablecoin
A type of crypto-asset designed to maintain a stable value by referencing another asset or basket of assets, most commonly a fiat currency such as the US dollar. Stablecoins are distinct from unbacked crypto-assets whose value floats freely, though the term covers several different stabilization mechanisms rather than a single instrument.
Fiat-backed (asset-referenced) stablecoins
Stablecoins purportedly backed by reserves of fiat currency or equivalent liquid assets held by an issuer. The credibility of the peg depends on the composition, custody, and auditability of the underlying reserves, which vary by issuer and are not uniformly regulated across jurisdictions.
Crypto-collateralized stablecoins
Stablecoins backed by other crypto-assets, typically over-collateralized to absorb price volatility in the underlying collateral. These generally operate through smart contracts rather than a centralized reserve holder.
Algorithmic stablecoins
Stablecoins that attempt to maintain a peg through algorithmic supply adjustments rather than holding backing reserves. This mechanism carries distinct stability risks and should not be conflated with reserve-backed models.
Issuer and redemption arrangements
The party (where one exists) responsible for issuing tokens and honoring redemption. In many regimes an identifiable issuer may be treated as an obliged entity or subject to prudential and disclosure requirements; decentralized or issuer-less arrangements complicate the attribution of AML/CFT obligations.
Regulatory classification
How a stablecoin is categorized differs by jurisdiction. Under the EU's Markets in Crypto-Assets (MiCA) framework, for example, distinctions are drawn between asset-referenced tokens and e-money tokens, while other regimes may treat stablecoins as payment instruments, securities, or crypto-assets. Classification drives which obligations apply and should be confirmed against the applicable regulation.
AML/CFT relevance
Stablecoins can be used to store or transfer value and may feature in money laundering or terrorist financing typologies, particularly in the layering phase. Virtual asset service providers dealing in stablecoins are, in many jurisdictions, subject to customer due diligence, transaction monitoring, and travel-rule-type requirements consistent with the FATF standards on virtual assets, though implementation diverges.

Common questions

Answers to the questions practitioners most commonly ask about Stablecoin.

Does a stablecoin's peg to a fiat currency mean it carries no money laundering or financial crime risk?
No. The fact that a stablecoin is designed to hold a stable value relative to a reference asset does not reduce its exposure to illicit finance. Stablecoins can still be used in the placement, layering, or integration phases of money laundering, and their transferability and potential for pseudonymous holding may present risks comparable to, or in some respects distinct from, other virtual assets. Price stability is an economic feature, not a compliance control, and obliged entities dealing in stablecoins are generally still subject to applicable AML/CFT obligations.
Is a stablecoin the same thing as central bank digital currency (CBDC)?
No, these should not be treated as interchangeable. A stablecoin is typically issued by a private entity and aims to maintain value by reference to an asset or basket of assets, whereas a CBDC is a digital form of central bank money issued by a monetary authority. They differ in issuer, legal status, and the regulatory frameworks that may apply. Conflating the two can lead to incorrect assumptions about who bears redemption, reserve, and compliance obligations.
Which entities in a stablecoin arrangement may be treated as obliged entities for AML/CFT purposes?
This depends on the applicable regime and how activities are characterised. In many jurisdictions, entities that issue, exchange, transfer, or provide custody for stablecoins may fall within definitions of virtual asset service providers or similar categories, and can therefore be subject to registration or licensing and to AML/CFT obligations. Scope varies by jurisdiction and by the specific function performed, so entities should confirm their classification against the applicable regulation and guidance rather than assuming a single global standard applies.
How does the FATF Travel Rule apply to stablecoin transfers?
Where a stablecoin is treated as a virtual asset and the counterparties are virtual asset service providers, transfers may be subject to travel-rule-type requirements to collect and transmit originator and beneficiary information, as reflected in the relevant FATF Recommendations and their implementation in national law. Application depends on how each jurisdiction has transposed these standards, the thresholds adopted, and whether transfers involve unhosted or self-hosted wallets, which may be handled differently. Exact obligations and thresholds should be confirmed against the applicable local rules.
What customer due diligence considerations arise when onboarding customers who transact in stablecoins?
Obliged entities generally apply customer due diligence measures consistent with their AML/CFT obligations, which may include identifying and verifying the customer, understanding the nature and purpose of the relationship, and applying ongoing monitoring. For stablecoin activity, firms may also consider blockchain analytics, wallet attribution, and source-of-funds enquiries as part of a risk-based approach. These are measures to detect and mitigate risk rather than guarantees of prevention, and the intensity of measures may vary with assessed risk.
What transaction monitoring and red-flag indicators are relevant to stablecoin activity?
Firms may monitor for patterns such as rapid movement between wallets, use of mixing or obfuscation services, transfers involving higher-risk jurisdictions, and inconsistencies with a customer's expected profile. Such indicators are illustrative and not exhaustive, and the presence of any indicator does not by itself establish wrongdoing; it may warrant further review or, where thresholds are met, a suspicious activity or suspicious transaction report under the applicable regime. Monitoring approaches should be calibrated to the entity's risk assessment and the specific characteristics of stablecoin transfers.

Common misconceptions

All stablecoins are fully backed by fiat currency held one-to-one in reserve.
Stablecoins use several different stabilization mechanisms, including crypto-collateralization and purely algorithmic designs that hold no fiat reserves. Even among fiat-referenced stablecoins, reserve composition, custody, and audit practices vary by issuer, and reserve adequacy should not be assumed. Specific reserve arrangements should be verified against issuer disclosures and applicable regulation.
Because stablecoins hold a stable value, they carry little money laundering or terrorist financing risk.
Price stability does not reduce ML/TF risk. Stablecoins remain transferable stores of value that can appear in laundering typologies, particularly during layering. Risk depends on factors such as the transaction channel, counterparties, and the controls applied by any intermediating service provider, not on price behavior.
Stablecoins are unregulated and fall outside AML/CFT obligations.
Treatment varies by jurisdiction, but stablecoins and the service providers that deal in them are increasingly brought within AML/CFT frameworks consistent with the FATF standards on virtual assets, and within instruments such as the EU's MiCA framework. Whether and how a given stablecoin or arrangement is regulated depends on its classification and the applicable regime.

Best practices

Determine the regulatory classification of a given stablecoin in each relevant jurisdiction before assessing obligations, recognizing that categories such as asset-referenced tokens and e-money tokens under MiCA, or payment or securities treatment elsewhere, drive which requirements apply.
Distinguish the stabilization mechanism (fiat-backed, crypto-collateralized, or algorithmic) when assessing risk, and do not assume any stablecoin is fully reserve-backed without verifying issuer disclosures.
Identify whether an identifiable issuer or obliged entity exists in the arrangement, and assess how AML/CFT responsibilities are attributed where the structure is decentralized or issuer-less.
Apply risk-based customer due diligence, transaction monitoring, and travel-rule-type controls to stablecoin activity where you act as or engage a virtual asset service provider, treating these as measures to detect and mitigate risk rather than guarantees of prevention.
Treat stablecoin-related typologies and red flags as indicators warranting further review, not as proof of criminality, and pay particular attention to their potential role in the layering phase.
Confirm reserve, custody, and disclosure details, and any specific thresholds or requirements, against the applicable regulation rather than relying on generalized assumptions about stablecoins.
