The development of global guidelines for stablecoins has experienced a significant slowdown over the past year, sparking concerns among central bankers that regulatory gaps could lead to market fragmentation and increased risk. According to recent reports, Bank of England Governor Andrew Bailey, who chairs the Financial Stability Board, noted that progress on international stablecoin regulations has stalled. This development has raised concerns, with Bank for International Settlements General Manager Pablo Hernández de Cos emphasizing the importance of global cooperation to prevent a patchwork of disparate rules that companies could exploit. De Cos warned that without international alignment, companies may relocate to jurisdictions with less stringent oversight, a practice known as regulatory arbitrage.

This warning comes as major economies are pushing forward with their own frameworks, often with different timelines and approaches. The stablecoin sector has experienced significant growth over the past few years, with its current value standing at $320 billion, according to DeFiLlama. Tether's USDT and Circle Internet's USDC account 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 cautioned that sudden withdrawals could have a ripple effect throughout the market. To mitigate 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 stablecoin 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 passed the House last year and 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 DeFi oversight and ethics provisions.
