The development of global standards for stablecoins has decelerated over the past year, prompting concerns among central bankers about potential market fragmentation and heightened risk. Bank of England Governor Andrew Bailey, who chairs the Financial Stability Board, noted that progress on international rules has stalled, according to Reuters.

This slowdown is a concern, as highlighted by Bank for International Settlements (BIS) General Manager Pablo Hernández de Cos in a statement made in Japan. De Cos emphasized the importance of global coordination to prevent the emergence of a patchwork of rules that companies could exploit, a practice known as regulatory arbitrage.

Without international alignment, firms may relocate their operations to jurisdictions with less stringent oversight. This warning comes as major economies are moving forward with their own regulatory frameworks, often with differing timelines and approaches. The stablecoin sector has experienced significant growth over the last few years, now accounting for $320 billion, with Tether's USDT and Circle Internet's USDC comprising the majority of this figure, according to DeFiLlama. De Cos noted that the structure of these stablecoins can more closely resemble securities than traditional cash, pointing out that difficulties in redemption can cause their prices to deviate from their intended value of $1.

He also highlighted the potential for sudden withdrawals to have a ripple effect through markets. To reduce these risks, proposals include limiting interest payments on stablecoins and providing issuers with access to central bank lending facilities or deposit-insurance-type arrangements. Policymakers argue that such measures could enhance the safety of the sector while preserving its role in digital payments.

In the United States, lawmakers are working to advance the Digital Asset Market Clarity Act, which aims to establish federal rules for digital asset markets. The bill, which passed the House last year, is currently before the Senate, where Banking Committee Chairman Tim Scott and Agriculture Committee Chairman John Boozman are leading the effort. Senators Thom Tillis and Angela Alsobrooks have negotiated a compromise on stablecoin yield that could pave the way for a markup, while Senator Cynthia Lummis, who chairs the Banking Committee's digital assets subcommittee, has indicated that a hearing could take place in the second half of April.

However, a deal remains contingent on resolving several outstanding issues, including oversight of DeFi and ethics provisions.
