BNY Mellon, one of the world’s largest global custodians with $57.8 trillion in assets under management, has taken a notable step toward integrating traditional banking infrastructure with blockchain technology. The bank has introduced a capability that allows its institutional clients to make deposits using blockchain-based systems. This development is designed to support continuous deposit activity for functions such as collateral management, margining, and payments, reflecting a shift away from the limitations of conventional banking hours.
The bank has indicated that its objective is to eventually operate the service on a continuous basis, aligning more closely with the always-on nature of digital markets. Although the service is not yet fully available around the clock, several major institutions have already begun using it. Early participants include firms such as ICE, Citadel Securities, DRW Holdings, Ripple Prime, Baillie Gifford, and Circle, signaling strong institutional interest in blockchain-enabled banking tools.
Enhancing, Not Replacing, Traditional Banking
BNY Mellon has clarified that the initiative is not intended to replace existing banking systems. Instead, the bank is focused on improving traditional financial infrastructure by integrating blockchain in a way that remains familiar, regulated, and trusted by large financial institutions. By combining established custody and deposit services with distributed ledger technology, the bank aims to modernize settlement and liquidity management without abandoning the safeguards of the traditional banking model.
A key element of this initiative is the concept of tokenized deposits, which are often compared to stablecoins but differ in important ways. Stablecoins are typically backed by cash or government securities held outside the traditional banking system. Tokenized deposits, by contrast, remain within regulated banks and represent actual customer deposits. Because they are held on bank balance sheets, these deposits can accrue interest, preserving features that institutional clients expect from conventional banking products.
Regulatory Context and Market Relevance
The distinction between stablecoins and tokenized deposits has gained attention following recent regulatory developments in the United States, including the passage of the GENIUS Act. The legislation has brought greater clarity to stablecoin regulation and has intensified discussions around new digital representations of money within the banking system. Against this backdrop, tokenized deposits are increasingly viewed as a bridge between established financial frameworks and emerging digital asset markets.
For BNY Mellon, tokenized deposits are seen as a foundation for expanding blockchain-based activity into other asset classes such as equities and fixed income instruments. Traditional banking systems typically rely on batch processing at the end of the business day. Tokenized deposits, however, can support transactions at any time, potentially transforming how liquidity and settlement are managed across markets.
Real-Time Settlement and Programmable Features
Institutions such as ICE have expressed plans to integrate blockchain-based deposits across their clearinghouses to support continuous trading environments. The use of tokenized deposits is expected to improve the real-time transfer of collateral, reducing the need for excess capital buffers that are often required to manage settlement delays.
Another notable feature of these deposits is their programmability. Because they operate on blockchain infrastructure, deposits can be configured to execute automatically when predefined conditions are met. Examples include the immediate release of collateral following loan repayment or the instant fulfillment of margin requirements when thresholds are reached. These capabilities introduce efficiencies that are difficult to achieve within legacy systems.
A Broader Industry Shift
BNY Mellon’s move aligns with a broader trend among traditional banks exploring blockchain-based deposit solutions. JPMorgan has already introduced its own institutional payment coin, while HSBC has announced plans to roll out additional tokenized deposit services in markets such as the United States and the UAE. In Europe, Barclays has invested in Ubyx, a startup focused on tokenized deposit infrastructure, while institutions including UBS, PostFinance, and Sygnum Bank have conducted pilots involving blockchain settlement. SWIFT has also been developing tools to support on-chain settlement.
Collectively, these initiatives suggest that the financial industry is entering a new phase of evolution. Rather than competing directly with cryptocurrencies, major banks are using blockchain technology to modernize existing instruments. BNY Mellon’s launch indicates that tokenized deposits may serve as a key catalyst in enabling smoother interaction between traditional finance and digital markets.
