FSB Urges G20: Stablecoin Cross-Border Regulation Lags, AI Cyber Threats Force Financial Institutions to Self-Protect

FSB Warns of Immature Stablecoin Regulation and AI Security Risks Ahead of G20 Meeting

The Financial Stability Board (FSB) has issued a stark warning on the eve of the G20 finance leaders’ meeting, highlighting the immaturity of cross-border regulation and crisis resolution mechanisms for stablecoins. The board also urged nations to support newly finalized guidelines for the responsible use of Artificial Intelligence (AI), emphasizing the need to prevent cybersecurity vulnerabilities stemming from generative AI from destabilizing the financial system.

Call for Stronger Financial Safety Nets

In a public letter addressed to G20 finance ministers and central bank governors, FSB Chair Andrew Bailey stated on Monday that current cross-border regulatory frameworks for stablecoins are “immature or not yet established.” He also cautioned about the potential cybersecurity threats posed by AI, calling for stronger financial safety nets to be supported at the upcoming G20 meeting on Thursday.

The letter serves as a formal policy initiative from the FSB ahead of the G20 finance leaders’ summit, aiming to foster consensus among the world’s largest economies on stablecoin regulation and AI risk management.

Stablecoin Regulation Lags in Major Economies

According to Bailey’s letter, the FSB’s 2025 global review found that only 11 out of 28 surveyed jurisdictions have formally completed their stablecoin regulatory frameworks. This indicates that nearly 70% of major economies are still in the process of developing or have yet to legislate these measures, leaving cross-border coordination virtually nonexistent.

Stablecoin Runs Pose Systemic Risk

In an accompanying report, the FSB further warned that stablecoin runs could spill over into traditional financial markets. During a large-scale redemption event, issuers might be forced to sell their reserve assets, such as short-term government bonds or bank deposits, potentially triggering bank runs or liquidity crises in the bond market. The situation becomes more complex with “multi-issuer stablecoins,” where redemption demands concentrate on a single issuer, but their reserve assets are spread across different jurisdictions, rendering cross-border clearing and coordination mechanisms underdeveloped.

This is not the first time the FSB has raised such concerns. In 2025, European Central Bank President Christine Lagarde had already warned of the potential for overlapping redemption risks between stablecoins issued within and outside the European Union, noting that a single market could struggle to remain insulated during a panic-driven withdrawal.

AI Risks Demand Vigilance

Beyond stablecoins, the FSB is also promoting an AI risk management framework. Bailey stated in his letter that “AI requires our continued high attention and careful management by financial institutions.” The FSB released a draft of 12 responsible AI practices in June, covering institutional-level governance, AI development and deployment processes, cybersecurity defenses, and third-party service provider risks. These guidelines have now been formally finalized ahead of the G20 meeting.

The FSB specifically highlighted the amplified cybersecurity threats posed by AI. Generative AI lowers the technical barrier for cyberattacks, enabling hackers to more quickly and precisely simulate social engineering attacks, forge documents, and even automate the scanning of financial infrastructure for vulnerabilities. This places unprecedented pressure on the resilience of critical financial institutions and market infrastructure.

These concerns are not isolated. In July, several European central bank governors warned that advancements in AI technology could exacerbate market volatility and cybersecurity risks. The FSB’s guidelines are being accelerated within this context, aiming to establish a global defense line.

G20 Faces Challenges in Consensus Building

The G20 finance leaders’ meeting is a crucial forum for global financial regulatory coordination. However, member states have historically shown divergent stances on cryptocurrency and stablecoin issues. The United States favors a market-led approach, the European Union has advanced the MiCA framework, China continues to prohibit cryptocurrency trading, and emerging markets are navigating between dollar hegemony and digital sovereignty. By linking stablecoins and AI, the FSB may be attempting to leverage “financial stability” as a common language to garner broader support.

Voluntary Adoption Remains a Key Hurdle

It remains to be seen how the G20 will respond. The FSB itself lacks legislative power, and its guidelines rely on voluntary adoption by member nations. If G20 members fail to provide clear commitments at this meeting, the regulatory vacuum for cross-border stablecoin oversight could widen. This is particularly concerning given recent developments such as Tether’s partnership with the National Bank of Kazakhstan and WLFI’s promotion of USD1, which indicate that stablecoin issuers are increasingly bypassing traditional regulatory frameworks and establishing direct partnerships with central banks.

For Taiwan, the FSB’s warning offers an important reference point. Stablecoin regulation is not merely a question of “whether to allow” but a systemic challenge of “how to achieve cross-border coordination.” In the absence of a consistent regional framework, unilateral legislation could expose local financial systems to offshore risks.
