The development of global standards for stablecoins has experienced a significant 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, recently stated that progress on international regulations has come to a halt.

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. De Cos warned that without international alignment, companies may relocate to jurisdictions with more lenient oversight, a practice known as regulatory arbitrage. Major economies are currently pushing forward with their own frameworks, often with different approaches and timelines.

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 making up the majority of this figure. De Cos noted that the structure of stablecoins can resemble securities more than cash, and that redemption frictions can cause prices to deviate from their intended value of $1. He also highlighted the risk of sudden withdrawals having a ripple effect on 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 would 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, which could pave the way for a markup, while Senator Cynthia Lummis has stated that a hearing could take place in the second half of April.

However, a deal remains contingent on resolving several open questions, including DeFi oversight and ethics provisions.
