Stablecoins vs. Tokenized Bank Deposits: Why Composability, Yield, and Regulatory Agility Position Stablecoins to Dominate Digital Banking

The digital banking landscape is undergoing a seismic shift as stablecoins and tokenized bank deposits vie for dominance. While both innovations leverage blockchain technology to modernize financial infrastructure, stablecoins are emerging as the superior force due to their composability, yield generation capabilities, and regulatory adaptability. This analysis examines why stablecoins are poised to outpace tokenized deposits in shaping the future of digital finance.

Composability: The Cornerstone of DeFi Innovation

Stablecoins thrive in decentralized finance (DeFi) ecosystems due to their unparalleled composability-the ability to be seamlessly integrated into multiple applications and protocols. Unlike tokenized bank deposits, which are often confined to permissioned networks and require KYC/AML compliance for access, according to Markets.com, stablecoins operate on open, permissionless blockchains. This allows them to be used as collateral in lending protocols, liquidity pools, and automated market makers (AMMs) without intermediaries, according to Fireblocks.

For example, stablecoins like Ethena's USDe and Falcon Finance's USDf are designed to generate yields through delta-neutral arbitrage, staking, and Treasury-backed strategies, according to CryptoBriefing. These mechanisms enable stablecoins to function as programmable money, automating financial workflows and reducing friction in cross-border transactions, as Fireblocks explains. In contrast, tokenized deposits such as JPM Coin or DCJPY are limited to institutional-grade use cases, such as real-time remittances for corporations, ABeam notes, but lack the flexibility to interact with retail-focused DeFi platforms.

Yield Generation: Stablecoins Outpace Tokenized Deposits

Stablecoins are redefining yield generation in digital banking by offering higher returns and diversified strategies. Projects like USDY (Ondo Finance) tokenize short-term Treasuries and bank deposits to deliver 4.1–4.5% APY, while USDf and USDe employ multi-strategy approaches-leveraging arbitrage, staking, and perpetual swap funding rates-to achieve 8–12% APY. These yields are generated on-chain, enabling real-time compounding and transparency.

Tokenized deposits, by contrast, rely on the issuing bank's infrastructure to generate returns. For instance, JPM Coin streamlines cross-border settlements but does not offer yield to token holders. Similarly, DCJPY in Japan focuses on operational efficiency rather than yield generation. While tokenized deposits benefit from deposit insurance and regulatory alignment, they lack the innovation and scalability of stablecoin yield models.

Regulatory Agility: Navigating a Fragmented Landscape

Regulatory scrutiny remains a critical challenge for both stablecoins and tokenized deposits. However, stablecoins have demonstrated greater agility in adapting to evolving frameworks. In Japan, stablecoins like JPYC and Progmat Coin are being integrated into B2C/B2B transactions under the Payment Services Act, which now permits asset backing via term deposits and government bonds, as reported by ABeam. South Korea's KRW1 stablecoin, developed by BDACS on Circle's Arc blockchain, further illustrates this adaptability by connecting Korean institutions to global stablecoin networks, according to Bitget.

Tokenized deposits, while aligned with traditional banking regulations, face limitations in scalability. For example, the BIS notes that stablecoins outperform tokenized deposits in meeting the "singleness of money" principle, as they avoid the operational constraints of bank-centric systems. Meanwhile, the FSB acknowledges gaps in stablecoin regulation but highlights their potential to drive innovation if frameworks evolve.

Counterarguments and the Path Forward

Critics argue that tokenized deposits, such as those issued by Custodia and Vantage Banks, mitigate disintermediation risks by keeping funds within traditional banking systems, Coinotag reports. Citigroup CEO Jane Fraser has even advocated for tokenized deposits as the future of digital payments due to their lower compliance burdens, according to a Coinotag report. However, these advantages are offset by stablecoins' broader accessibility and composability.

The U.S. Treasury projects the stablecoin market to grow from $300 billion to $2 trillion by 2028, underscoring institutional confidence in their potential. Regulatory sandboxes, such as Malaysia's Digital Asset Innovation Hub, further validate stablecoins as a bridge between legacy finance and decentralized ecosystems.

Conclusion

Stablecoins are uniquely positioned to dominate the digital banking landscape due to their composability, yield innovation, and regulatory adaptability. While tokenized deposits offer safety and compliance, they lack the versatility and scalability required to meet the demands of a rapidly evolving financial ecosystem. As jurisdictions like Japan and South Korea refine their frameworks, stablecoins will continue to outpace tokenized deposits in driving the next wave of financial innovation.
