Brookings warns stablecoin fragmentation could slow digital dollar payments

Brookings has spotlighted a growing challenge in the evolution of digital dollar payments, arguing that fragmentation across USD-backed stablecoins and tokenized bank deposits could limit efficiency gains unless interoperability improves. The analysis points to a market where users often need to depend on crypto exchanges or decentralized finance liquidity pools to move value between different stablecoins, introducing friction into what is often promoted as a seamless digital payment ecosystem.

The think tank draws a sharp contrast between stablecoins and tokenized deposits. Stablecoins can circulate across public blockchain networks, but moving between issuers typically requires third-party venues such as exchanges or DeFi protocols. Tokenized deposits, by comparison, are tied more directly to the banking system and benefit from protections such as deposit insurance up to $250,000 and access to lender-of-last-resort support. Even so, they face a major limitation of their own: there is still no universal framework for interbank settlement of tokenized deposits on private blockchains.

Key Details

Brookings notes that traditional bank deposits already have a form of interoperability because they are connected through Federal Reserve payment rails. While those rails are not always real-time or continuously available on a 24/7 basis, they still provide the settlement backbone that enables money to move across institutions. Tokenized deposits operating on private blockchain systems do not yet have an equivalent shared settlement infrastructure, leaving banks and clients dependent on bilateral or platform-specific arrangements.

This gap is beginning to drive experimentation among large financial institutions. Brookings points to efforts such as Citi’s integration of tokenized deposits with its existing clearing services. The model is designed to support cross-border payments for clients connected to more than 250 banks across 40 markets, offering a glimpse of how blockchain-based bank money could eventually function in a more connected global payments environment.

Industry Impact

The broader industry implication is that speed alone will not determine the success of digital payment instruments. For stablecoins and tokenized deposits to compete with or complement existing banking rails at scale, they will need credible interoperability, consistent settlement mechanisms, and trust frameworks that reduce counterparty and liquidity risks. Without those building blocks, users may continue to face conversion costs, operational complexity, and uneven access across networks.

For banks, policymakers, and payment providers, the Brookings assessment reinforces an important point: the next phase of digital money development will depend less on issuing new tokenized instruments and more on connecting them effectively. If institutions can create secure cross-chain and cross-bank settlement models, tokenized deposits could strengthen cross-border payments and treasury operations. If not, fragmentation may remain a core obstacle to mainstream adoption.
