Stablecoins and Tokenization: Exploring Risks and Opportunities

The IMF, in an article by Hélène Rey, explores how stablecoins, tokenization, and CBDCs could reshape the international monetary system. Their impact will hinge on regulation, global cooperation, and technological innovation, with implications ranging from capital flows and the dollar’s dominance to financial stability, monetary fragmentation and financial disintermediation, and cybersecurity risks.

Key Takeaways:

• Stablecoins: These privately issued digital instruments, operating on blockchain technology, are typically backed by fiat currencies, mainly through liquid assets such as US Treasuries. Their appeal lies in the potential to lower costs and accelerate cross-border payments and remittances, particularly in countries with weak financial systems, high transaction costs, or restrictions stemming from sanctions and capital controls. However, since most existing stablecoins are pegged to the US dollar, their widespread adoption in other economies—while reinforcing the dollar’s dominance and boosting demand for US Treasury debt—could also generate a range of risks: competition with domestic currencies, money laundering, deposit outflows into stablecoins, greater exposure of bank balance sheets to US Treasuries at the expense of credit provision, fiscal revenue erosion, and, ultimately, the privatization of seigniorage. These dynamics could destabilize the international financial system and concentrate wealth, influence, and payment data in the hands of a few private actors.
  
  
• Tokenization is the process of recording claims on assets—whether traditional (such as equities, bonds, or real estate) or natively digital—on a programmable blockchain-based platform, enabling their secure and efficient transfer, fractionalization, and trading. This technology makes it possible to integrate messaging, reconciliation, and asset transfer on a unified ledger, while enabling new functionalities such as programmability. Central bank digital currencies (CBDCs) could play a pivotal role in these infrastructures. Linking CBDCs across countries would allow international payments to be carried out more quickly and efficiently, reducing reliance on intermediaries. Such interoperability would expand access to both public and private assets —including stablecoins— on a global scale. While the US dollar would have a head start in becoming the common reference unit of account, concerns about monetary sovereignty and data control suggest that, in practice, a multiplicity of interconnected platforms with different restrictions is more likely. This would limit the full benefits of tokenization and underscores the need for international cooperation and regulation to avoid fragmentation and reduce financial fragility.
  
  
• Cybersecurity: Realizing the benefits of these innovations will hinge on the resilience of digital platforms and assets against cyberattacks, particularly in light of the challenges posed by quantum computing. Networks that prove most credible and secure against digital fraud will enjoy an “integrity privilege”, reflected in lower financing costs and greater trust, thereby enhancing their attractiveness and long-term viability.
