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, 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 cooperation to avoid a patchwork of rules that companies could exploit. De Cos warned that without international alignment, firms may relocate to jurisdictions with less stringent oversight, a practice known as regulatory arbitrage. As major economies move forward with their own frameworks, often with differing timelines and approaches, the stablecoin sector has grown significantly over the past few years, now accounting for $320 billion. The sector's structure, particularly for major players like Tether's USDT and Circle Internet's USDC, can resemble securities more than traditional currency, with redemption frictions potentially causing price deviations from their intended value.

De Cos also highlighted the risk of sudden withdrawals triggering market instability. 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 sector's safety 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, currently before the Senate, seeks to provide clarity and oversight to the sector, with senators negotiating compromises on key aspects such as stablecoin yield and DeFi oversight.
