The development of global standards for stablecoins has decelerated 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.

Bank for International Settlements General Manager Pablo Hernández de Cos expressed concern about this slowdown, emphasizing the need for global cooperation to prevent a patchwork of regulations that companies could exploit by shifting operations to jurisdictions with less stringent oversight. Major economies are moving forward with their own frameworks, often with different timelines and approaches, which could lead to regulatory arbitrage.

The stablecoin sector has grown significantly 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 bulk of this figure. De Cos pointed out 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 warned that sudden withdrawals could have 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 has passed the House and is currently before the Senate, where lawmakers are pushing for its passage. A compromise on stablecoin yield has been negotiated, which could pave the way for a markup, and a hearing is expected in the second half of April.

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