The development of global standards for stablecoins has experienced a significant slowdown over the past year, prompting concerns among central bankers that regulatory gaps could lead to market fragmentation and increased risk. Bank of England Governor Andrew Bailey, who chairs the Financial Stability Board, noted that progress on international rules has stalled, according to recent reports. This development has raised concerns, with Bank for International Settlements (BIS) General Manager Pablo Hernández de Cos emphasizing the importance of global cooperation in a statement made in Japan. De Cos warned that the lack of international alignment could result in a patchwork of regulations, which companies might exploit by shifting their operations to jurisdictions with less stringent oversight, a practice known as regulatory arbitrage.

This warning comes as major economies move forward with their own regulatory frameworks, often with different timelines and approaches. The stablecoin sector has experienced significant growth over the past few years, with a current value of $320 billion, according to DeFiLlama, with Tether's USDT and Circle Internet's USDC accounting for the majority of this figure. De Cos noted that the structure of these stablecoins can resemble securities more than traditional currency, highlighting the potential for redemption frictions to push prices away from their intended value of $1. He also emphasized the potential risks associated with sudden withdrawals, which could have a ripple effect on markets.

Proposed measures to mitigate these risks 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 efforts to move it forward.

Senators Thom Tillis and Angela Alsobrooks have negotiated a compromise on stablecoin yield, which 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 DeFi oversight and ethics provisions.
