The development of global standards for stablecoins has experienced a slowdown over the past year, sparking 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, as reported by Reuters. This slowdown has raised concerns, with Bank for International Settlements General Manager Pablo Hernández de Cos emphasizing the importance of global cooperation to prevent a patchwork of regulations 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 proceed with their own regulatory frameworks, often with different timelines and approaches, the stablecoin sector continues to grow, now valued at $320 billion according to DeFiLlama, with Tether's USDT and Circle Internet's USDC making up the majority of this figure. De Cos pointed out that the structure of stablecoins can resemble securities more than cash, 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 make the sector safer 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, which passed the House last year, is currently before the Senate, where lawmakers are pushing for its approval. A potential compromise on stablecoin yield could pave the way for a markup, while a hearing is expected to take place in the second half of April. However, a deal remains contingent on resolving several outstanding issues, including DeFi oversight and ethics provisions.
