#What are the Challenges with Stablecoins?
The recent Annual Economic Report from the Bank for International Settlements highlights significant challenges that stablecoins face. A key issue is their lack of essential monetary properties, particularly a concept referred to as singleness. This means stablecoins need to be convertible to central bank money at face value, and without this guarantee, they fall short as reliable payment mediums.
In the report, the authors outline four major structural shortcomings of stablecoins that operate on public, permissionless blockchains. First, the question of redeemability arises. Stablecoins do not always ensure that users can cash out at their face value. Next is liquidity elasticity, which refers to stablecoins' inability to adjust their supply in response to market fluctuations, a flexibility that is a hallmark of central bank options. Additionally, the interoperability among various stablecoin systems remains fragmented, limiting their effectiveness across different platforms. A further concern is the vulnerability to financial crime that open blockchains face, posing sizable risks to the ecosystem.
The report warns that an increased adoption of USD-denominated stablecoins could threaten monetary sovereignty in emerging markets. Furthermore, if depositors start to withdraw funds from traditional banks in favor of stablecoins, banks could lose a vital source of low-cost funding, which may in turn restrict their ability to extend credit. Despite these factors, the BIS expects only a modest impact on overall economic growth.
#How Can a Unified Ledger Help?
The BIS proposes an alternative framework that involves a unified ledger, aiming to merge the technological advantages inherent in tokenization and programmability with the established two-tier monetary system. Ideally, this framework would allow tokenized central bank reserves to underlie the system, providing the much-needed guarantee of singleness that current stablecoins lack. In this model, commercial banks and other regulated entities would have the ability to issue tokenized deposits and payment instruments, leveraging these reserves.
Project Agora exemplifies this approach, serving as an innovation hub for collaboration on cross-border payments. The BIS also underscores the necessity for coordinated regulatory measures, targeting existing stablecoin operations to ensure greater security and stability in the financial landscape.
