The development of global guidelines for stablecoins has experienced significant delays over the past year, sparking concerns among central bankers about potential market fragmentation and increased risk. Andrew Bailey, Governor of the Bank of England and Chairman of the Financial Stability Board, noted that progress on international regulations has come to a standstill, according to recent reports. This lack of progress has raised concerns, with Pablo Hernández de Cos, General Manager of the Bank for International Settlements, emphasizing the importance of global cooperation to prevent a patchwork of regulations that companies could exploit. Without aligned international regulations, 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 at different paces and with varying approaches, the stablecoin sector has grown substantially over the past few years, now accounting for $320 billion, according to DeFiLlama, with Tether's USDT and Circle Internet's USDC making up the majority of this figure. De Cos highlighted that the structure of stablecoins can be more similar to securities than cash, with redemption frictions potentially causing prices to deviate from their intended value of $1.

He also warned about the potential for sudden withdrawals to have a ripple effect on markets. To mitigate these risks, proposals include capping interest payments on stablecoins and providing issuers with access to central bank lending facilities or deposit insurance-like 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 regulations for digital asset markets. The bill, which passed the House last year, is currently before the Senate, where committee chairs Tim Scott and 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 indicated that a hearing may take place in the second half of April.

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