Global watchdogs found crypto rulebooks fragmented across jurisdictions

Global standard-setters found implementation gaps

On October 16, 2025, the Financial Stability Board and the International Organization of Securities Commissions published coordinated reviews finding that national crypto rulebooks remained uneven, with stablecoin oversight lagging and cross-border enforcement still fragmented.

The FSB review covered 37 jurisdictions, including 13 selected non-members, and assessed information generally current through August 2025. It examined financial-stability regulation for crypto-asset service providers and global stablecoin arrangements, along with data reporting and cooperation between authorities. IOSCO separately examined 20 jurisdictions and a subset of 10 of its 2023 recommendations, concentrating on governance, conflicts, market abuse, custody, retail-client protections, disclosures and regulatory cooperation.

The paired exercise mattered because it shifted the international debate from writing high-level principles to testing whether countries had actually built compatible supervisory systems. Neither organization writes domestic law. Their findings nevertheless supplied G20 authorities and securities regulators with a common map of where exchanges, custodians and stablecoin arrangements could face materially different rules across borders.

Stablecoin frameworks were further behind

The FSB found notable progress but did not treat an announced bill, a consultation or a partial regime as equivalent to a finalized framework. In the report's applicable implementation tables, 11 jurisdictions had finalized a crypto-asset framework addressing financial stability, compared with five reporting a finalized stablecoin framework. The report also said alignment with its recommendations remained limited even where frameworks were final.

That gap was consequential for stablecoins because issuance, reserve assets, distribution and redemption can span several legal systems. The FSB's interpretation was that inconsistent definitions, divided supervisory responsibilities and incomplete cooperation can create regulatory-arbitrage opportunities. A firm or arrangement may locate important functions where requirements are lighter while serving users elsewhere.

IOSCO reached a complementary, narrower conclusion. Its review focused on investor protection and market integrity rather than the FSB's financial-stability mandate. It reported implementation progress, but called for greater consistency and stronger enforcement, including information sharing during authorization, supervision and enforcement. Read together, the reports did not say all jurisdictions lacked rules; they said the cross-border system was incomplete and inconsistent.

The market backdrop, with limits

The FSB placed the review against a rapidly expanding market. Using CCData and its own calculations, it estimated total crypto-asset market value at approximately $4 trillion in early August 2025, almost double the level one year earlier. It said unbacked crypto-assets represented more than 90% of that total. Stablecoins had risen by almost three-quarters over the same one-year comparison to just under $290 billion.

Those figures describe an early-August global market-value snapshot and a one-year comparison from an aggregator; they are not October 16 closing prices. Crypto trades continuously across venues, and the report did not establish that its publication caused any price movement on October 16, 2025. It also assessed implementation progress, not whether any national regime had proved effective in practice.

What was established on October 16

The verifiable development was the publication of two point-in-time implementation reviews and a joint information note. The central conclusion was institutional: international recommendations existed, but national execution—especially for global stablecoins, reporting and cross-border coordination—remained incomplete.

For exchanges and custodians, that implied continued differences in licensing, client-asset safeguards and reporting. For stablecoin issuers, it highlighted unresolved questions about reserve oversight, redemption rights and home-host supervision. For policymakers, the reports' eight FSB recommendations and IOSCO's proposed enhancements created a follow-up agenda rather than new binding obligations.

Later confirmation

On October 27, 2025, France's Autorité des marchés financiers summarized the October 16 publications and likewise described global implementation as uneven and fragmented. That later notice confirms the dated record; it does not convert the recommendations into law or demonstrate subsequent compliance.
