Stablecoins are increasingly embedded in the real economy, supporting faster settlement, cross-border payments, and programmable financial flaws. However, the Financial Action Task Force's (FATF) March 2026 targeted report underscores a critical point: the very features that make stablecoins attractive - liquidity, interoperability, and price stability - also create vulnerabilities, particularly through peer-to-peer (P2P) transactions using unhosted wallets, where regulated intermediaries may be absent.
The key implication is not that stablecoins are inherently unsafe. Rather, stablecoins change where financial-crime risk sits. In traditional payments, accountability is concentrated in institutions and schemes. In stablecoin arrangements, accountability shifts toward governance design, custody structures, issuer controls, and operating models.
Risk is not eliminated, it is re-located. As a result, the defining differentiator for firms is no longer compliance assertations, but the ability to evidence control across the stablecoin lifecycle.

Stablecoins as a governance challenge, not a technology question
The FATF report highlights the rapid expansion of stablecoins, with more than 250 stablecoins in circulation by mid-2025 and aggregate market capitalisation exceeding USD 300 billion. It also documents their increasing presence in illicit finance typologies, particularly where transactions occur directly between users without passing through AML/CFT-obliged intermediaries.
A focal point of the report is the unhosted wallet challenge. Where value moves directly between parties, traditional AML/CFT frameworks - built around intermediary visibility - are weakened. These challenges are further compounded by cross-chain activity, which can fragment transaction trails and complicate supervisory oversight.
Viewed through this lens, stablecoins should be assessed not as isolated instruments, but as arrangements: interconnected ecosystems involving issuers, intermediaries, custodians, wallet providers, and governance mechanisms. Supervisory and board‑level attention therefore shifts from the token itself to a more fundamental question: where does accountability reside within the arrangement, and how is it demonstrated?
From transparency to investigability
Blockchain‑based transactions are often described as transparent. However, transparency alone does not equate to investigability.
On‑chain records are typically pseudonymous and frequently lack essential contextual information, including customer identity and, in some cases, geographic attribution. Without this context, effective sanctions screening, transaction monitoring, and international cooperation become materially more difficult.
For this reason, the FATF reiterates the importance of applying Customer Due Diligence (CDD), sanctions screening, and—where applicable—the Travel Rule at critical interaction points between stablecoins and the regulated financial system, particularly at issuance, exchange, and redemption.
Controls must be embedded in the operating model
One of the most significant aspects of the FATF report is its emphasis on risk‑based technical and governance controls embedded directly into stablecoin arrangements.
The report highlights issuer‑level capabilities such as the ability to freeze, burn, or withdraw stablecoins in secondary markets, conduct due diligence at redemption, and, where proportionate, implement allow‑listing (restricting transactions to approved addresses) and deny‑listing (blocking high‑risk addresses).
This reflects an important regulatory shift. In stablecoin arrangements, controls are not confined to policies and procedures; they can be designed into the operating and contractual layers of the ecosystem.
The practical challenge for firms is therefore to demonstrate effective control outcomes at each stage of the stablecoin lifecycle - issuance, distribution, transfer, and redemption.
Designing a defensible assurance perimeter
For boards, compliance leaders, and payments strategists, the appropriate response is not to avoid stablecoins, but to design a defensible assurance perimeter that reflects how and where risk is concentrated.
A practical approach typically combines three layers:
Identity and attribution at the edges: Robust CDD, sanctions screening, and Travel Rule compliance remain essential where stablecoins interact with the regulated financial system, providing the contextual information that on-chain data alone cannot deliver.
Containment within the arrangement control plane: Issuer-level and arrangement-level controls, such as freezing, burning, or address restrictions, can serve as proportionate mechanisms to contain exposure and enable timely intervention when risk indicators arise.
Detect and disrupt capability: The FATF also emphasises the need for strong technical capability, including cross-chain analytics, and effective domestic and international cooperation mechanisms to support timely investigation and enforcement.
Together, these layers enable firms to demonstrate not only that controls exist, but that they operate effectively and can be evidenced.
Implications for Europe: convergence through governance
Across Europe, stablecoins increasingly sit at the intersection of payments regulation, digital asset frameworks, and financial crime controls. The FATF’s analysis reinforces the importance of ensuring that stablecoin arrangements do not fall between regulatory regimes, and that Recommendation 15 of the FATF Standards is fully implemented.
In practice, firms will be expected to evidence:
how P2P and unhosted wallet risks are identified and managed,
how cross-chain activity is monitored and investigated, and
how governance and operating models align with supervisory expectations
This reflects a broader reality: convergence in financial services is being driven by governance and accountability, not technology alone.
Where Grant Thornton can help
Addressing stablecoin risk requires more than regulatory interpretation. It demands integrated support across strategy, operating model design, and assurance.
Grant Thornton supports clients across the stablecoin and digital asset ecosystem by:
Advising on regulatory interpretation and supervisory expectations, including the interaction between payments, digital asset, and AML/CFT regimes;
Designing governance and operating models that clearly allocate accountability across issuers, intermediaries, custodians, and service providers;
Building and enhancing control frameworks, including transaction monitoring, sanctions controls, and issuer‑level containment mechanisms; and
Providing assurance and evidencing services, helping firms demonstrate that controls are effective, proportionate, and defensible to regulators, counterparties, and boards.
As stablecoins continue to scale, the ability to demonstrate stable accountability, through clear governance, embedded controls, and credible evidence, will be central to sustainable growth.
The FATF’s latest report does not signal a retreat from stablecoins. It signals the end of an era in which compliance could be asserted rather than demonstrated.
The firms that succeed in the next phase of stablecoin adoption will be those that can show where risk sits, how it is controlled, and how that control can be evidenced, across the full value chain.
