BNY Brings Trillions in Fund Records Onchain as Finance Rebuilds Its Rails

Bank brings transfer agency operations to blockchain as traditional finance builds rails for tokenized funds

Bank of New York Mellon (BNY) is moving one of its core fund administration functions onto blockchain as Wall Street accelerates efforts to build infrastructure for tokenized financial markets.

The move will see BNY transition parts of its transfer agency operations — the business responsible for maintaining ownership records of investment funds — to an onchain system designed to create a unified record of fund ownership and reduce reliance on multiple intermediaries.

“We think of BNY as modernizing a function that sits behind every single fund transaction by bringing the books and records onchain,” Carolyn Weinberg, BNY’s chief product and innovation officer, told the Financial Times.

BNY, one of the world’s largest asset servicing institutions, oversees more than $59 trillion in assets under custody and administration and services approximately $8.6 trillion in assets across 7.6 million accounts. The bank said blockchain-based record keeping could streamline processes by creating a single source of ownership data across the fund lifecycle.

The initiative reflects a broader shift among traditional financial institutions: rather than replacing existing financial infrastructure, blockchain is increasingly being integrated into specific operational layers where it can improve efficiency, transparency, and settlement processes.

Tokenization moves from asset creation to ownership infrastructure

BNY’s blockchain initiative will initially support tokenized fund structures, with Scottish investment firm Baillie Gifford expected to use the service for what the companies describe as the first fully native U.K.-regulated tokenized fund.

The service could also support future tokenized products from major asset managers, including BlackRock and BNY’s Dreyfus money-market and cash-management business.

Tokenized funds have gained momentum among institutional investors in recent years, particularly in the money-market sector. Products launched by firms such as BlackRock and Franklin Templeton represent traditional investment vehicles — including short-term debt and cash instruments — issued through blockchain-based ownership structures.

The development signals that tokenization is moving beyond pilot programs and toward integration with established fund infrastructure.

BNY targets the hidden inefficiencies behind trillion-dollar markets

BNY’s approach highlights an important distinction in the evolution of institutional blockchain adoption.

The bank is not positioning blockchain as a replacement for traditional markets. Emily Portney, BNY’s global head of asset servicing, noted that trillions of dollars in funds will continue operating on traditional systems for years.

Instead, blockchain is being deployed where financial institutions see measurable operational advantages, particularly in record keeping, reconciliation, and ownership tracking.

The current fund administration system often relies on multiple parties maintaining separate records, creating additional reconciliation requirements. A shared blockchain ledger could reduce these inefficiencies by providing a synchronized ownership record.

However, challenges remain. Blockchain-based financial infrastructure introduces new risks, including smart contract vulnerabilities and security concerns related to interoperability between different networks.

Banks are competing for the infrastructure layer of digital finance

BNY’s move comes as major financial institutions increasingly explore blockchain-based infrastructure for deposits, securities, and settlement.

Several large U.S. banks, including JPMorgan, Citi, and Bank of America, are reportedly developing a shared tokenized deposit network aimed at modernizing payment infrastructure and responding to the growing role of stablecoins in financial markets.

The developments reflect a broader transition: Wall Street’s blockchain strategy is increasingly focused on rebuilding financial infrastructure rather than creating standalone crypto products.

For institutions managing trillions of dollars, the value proposition is not simply issuing assets onchain. It is creating more efficient systems for moving, recording, and settling ownership.

BNY’s decision demonstrates that blockchain adoption among traditional finance players is entering a new phase — one where the technology becomes embedded quietly behind existing markets rather than operating as a separate financial ecosystem.
