The world’s oldest bank moves $8.6 trillion in assets onto the blockchain— the tokenization race for infrastructure is officially on
BNY (Bank of New York Mellon), founded in 1784, the oldest bank in the United States, today announced that it is migrating the accounting systems for its core transfer agency business onto the blockchain. This business manages $8.6 trillion in assets and 7.6 million accounts. BNY’s total custody assets exceed $59 trillion— the largest in the world.
First, some background: What is “tokenization”?
It means converting ownership records of traditional financial assets (funds, bonds, deposits) from paper/database formats into tokens on the blockchain. Benefits: 24/7 settlement, instant transfers, and lower intermediary costs.
What is a transfer agent?
When you buy a fund, an institution behind the scenes keeps track of “how many shares/units you own, when you bought, when you sold.” Traditionally, these records are distributed across multiple intermediary institutions, and each reconciliation takes time and costs. BNY moves this layer onto the chain = one chain, one record, replacing multi-layer reconciliation among intermediaries.
A glance at the client list shows this isn’t just playing around:
• Baillie Gifford ($261 billion AUM)— the first fully compliant UK tokenized fund
• BlackRock — a tokenized fund in the works
• Dreyfus under BNY — money market funds
Why is this piece of news worth digging into?
1️⃣ Not a pilot—this is a production system
Previously, BlackRock’s BUIDL and Franklin Templeton’s BENJI launched tokenized money market funds, but those were single products. What BNY is moving this time is the underlying accounting infrastructure—the foundational infrastructure for all fund transactions. It’s like “opening a shop” versus “building the foundation of an entire mall.”
2️⃣ Old systems won’t disappear—pragmatism over idealism
BNY makes it clear: traditional rails and blockchain will coexist for many years. Why? Because smart contracts carry bug risks, cross-chain bridges have security vulnerabilities, and network attacks pose threats. This judgment matters a lot— a 242-year-old bank wouldn’t bet its life on it. By choosing “two legs to walk,” it means tokenization isn’t replacing traditional finance—it’s enhancing it.
3️⃣ Big banks take collective action—race to the infrastructure layer
JPMorgan, Citi, and Bank of America plan to launch a shared tokenized deposit network in the first half of 2027. BNY is taking the lead now, going after the “accounting layer” for tokenized funds. This situation resembles traditional finance’s AWS: everyone uses the same infrastructure, and each party issues its own products. If you build the infrastructure, you collect tolls.
4️⃣ Stablecoin’s structural counterparty
Big banks launching tokenized deposit networks = using their own on-chain dollars to replace USDT/USDC. Banks won’t stand by and let deposits flow out to stablecoins. Long term, the business model that Tether/Circle faces isn’t just regulatory pressure—it’s banks personally stepping in.
⚠️ Risks you need to know:
• Smart contract vulnerabilities = an $8.6 trillion attack surface. But BNY uses a permissioned chain, reducing the attack surface compared with public chains
• Multi-chain standards aren’t unified—cross-chain transfers of tokenized assets are still an unsolved problem
• Fragmented compliance frameworks (U.S. vs UK vs EU vs Hong Kong)
• Technology upgrade cycles are measured in years—BNY builds trust over 242 years, but trust can vanish in a day
💡 Hong Kong perspective: HKMA is pushing the Ensemble project sandbox to explore wholesale tokenization and cross-chain settlement. BNY’s moves suggest that if Hong Kong doesn’t accelerate, the right to speak in tokenization infrastructure could shift to Wall Street.
Core view: Tokenization has already moved past the “whether it will happen” phase. Now the questions are “who builds the infrastructure layer” and “who sets the standards.” BNY’s bet is: 242 years of trust + blockchain efficiency = an irreplaceable moat. If it succeeds, it won’t be “a crypto company,” but a charging station for the entire underlying tokenized finance stack.
What do you think? Will tokenized infrastructure built by traditional banks become monopolized or opened up?
