The development of global standards for stablecoins has experienced a significant slowdown over the past year, prompting 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 rules has stalled, according to recent reports. This slowdown has raised concerns, with Bank for International Settlements General Manager Pablo Hernández de Cos emphasizing the importance of global coordination 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, which could exacerbate risks.

Major economies are pushing forward with their own frameworks, often with differing timelines and approaches, which has led to a call for cooperation to avoid fragmentation risks. The stablecoin sector has grown substantially 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 traditional currency, and that redemption issues can cause prices to deviate from their intended value of $1. He also highlighted the potential risks of sudden withdrawals, which 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 aims to establish federal rules for digital asset markets. The bill has passed the House and is currently before the Senate, where committee chairs are leading the effort to push it forward.

While a compromise on stablecoin yield has been negotiated, a deal remains contingent on resolving several outstanding issues, including DeFi oversight and ethics provisions.
