Key Takeaways:
The Bank for International Settlements warned that the $316 billion stablecoin market risks fragmenting the global monetary system, urging central banks to accelerate work on tokenized forms of central bank and commercial bank money.
"Private digital tokens lack the institutional features required to serve as safe, reliable money at scale," the BIS said in its Annual Economic Report published June 28.
The Basel-based institution pointed to structural vulnerabilities in reserve asset management and warned that a significant migration from commercial bank deposits into stablecoins could reduce bank funding and constrain credit to the real economy. It focused particular attention on "stablecoin dollarization" — the growing use of dollar-denominated tokens in economies with weaker domestic currencies — saying the trend could weaken monetary sovereignty and erode the effectiveness of domestic monetary policy, especially in emerging markets.
Rather than rejecting tokenization, the BIS advocated a "unified ledger" architecture combining tokenized central bank money, commercial bank deposits and financial assets on regulated programmable platforms, arguing the approach preserves efficiency gains without sacrificing monetary stability or financial integrity.
The report also delivered one of the BIS's strongest critiques of public permissionless blockchains such as Bitcoin and Ethereum. It argued that decentralized networks relying on distributed validation lack the scalability, legal accountability and settlement finality required for systemically important financial infrastructure.
At the center of the critique is the economics of decentralized consensus. The BIS said public permissionless blockchains compensate validators through transaction fees that rise as network activity increases, making congestion, longer confirmation times and higher costs structural features rather than temporary technical shortcomings. These characteristics undermine the efficiency and network effects essential for a unified monetary system, according to the report.
The institution further argued that permissionless blockchains lack the clear governance and accountability frameworks required for institutional finance. Without an identifiable entity responsible for maintaining system integrity, resolving disputes or ensuring compliance with financial integrity standards, such networks face significant obstacles to supporting large-scale regulated financial activity, the BIS said.
Stablecoin dollarization and emerging market risks
The report's warning on stablecoin dollarization carries particular weight for emerging market economies. The BIS said demand for foreign stablecoins is increasingly connecting foreign exchange markets with the crypto ecosystem, exposing countries with weaker domestic currencies to volatile cross-border capital flows. The trend could reduce bank intermediation and constrain domestic lending as deposits shift from commercial banks into private digital tokens.
The BIS's stance signals to policymakers that the current regulatory approach to stablecoins may prove insufficient if private digital currencies continue expanding. Rather than positioning stablecoins as a durable foundation for the future monetary system, the institution said tokenized commercial bank deposits combined with tokenized central bank money on regulated infrastructures offer a more robust path.
A unified ledger alternative
The BIS's proposed unified ledger architecture would combine tokenized central bank money, tokenized commercial bank deposits and tokenized financial assets on programmable platforms operating within regulated legal and institutional frameworks. The approach preserves the benefits of tokenization — including programmable transactions and faster settlement — while maintaining the institutional foundations of the existing monetary system, the BIS said.
The report comes as more than 130 countries explore central bank digital currencies. The BIS's endorsement of tokenized central bank money over private stablecoins could accelerate CBDC development timelines and shape regulatory frameworks across jurisdictions including the European Union, the United States and Asia.
