The development of global standards 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, stated that progress on international regulations has stalled, 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 to prevent a patchwork of rules that companies could exploit, resulting in regulatory arbitrage.

De Cos warned that without international alignment, firms may relocate to jurisdictions with more lenient oversight. This warning comes as major economies push forward with their own frameworks, often with different approaches and timelines. The stablecoin sector has expanded significantly over the past few years, now accounting for $320 billion, with Tether's USDT and Circle Internet's USDC making up the majority of this figure.

De Cos noted that the structure of stablecoins can resemble securities more than cash, with redemption frictions potentially causing prices to deviate from their intended value of $1. He also highlighted the risk of sudden withdrawals rippling through 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 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, which could pave the way for a markup, while Senator Cynthia Lummis 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.
