The development of global guidelines for stablecoins has experienced a slowdown over the past year, sparking concerns among central bankers that inadequate oversight 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 regulations has come to a halt, according to a recent Reuters report. 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 speech in Japan on Monday. De Cos warned that without unified international standards, companies may take advantage of regulatory differences by shifting operations to areas with more lenient oversight, a practice known as regulatory arbitrage.

His warning comes as major economies are pushing forward with their own frameworks, often with varying timelines and approaches. The stablecoin sector has seen significant growth over the past few years, currently valued at $320 billion, according to DeFiLlama, with Tether's USDT and Circle Internet's USDC making up the majority of this figure. De Cos noted that the structure of these stablecoins can resemble securities more than traditional currency, and that difficulties in redeeming them can cause price fluctuations. He also cautioned that sudden withdrawals could have a ripple effect throughout the markets.

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 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 regulations 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, 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.
