The depository that holds $114 trillion has started to tokenize

The Depository Trust Company holds $114 trillion in securities in custody. On July 15, it moved some of them in a new way.

The central securities depository that holds most US equities and debt has executed tokenized transactions in production, with real counterparties and within its own systems. More than thirty firms took part, including BlackRock, J.P. Morgan, Goldman Sachs, Citadel Securities, CME Group, Nasdaq, the New York Stock Exchange, State Street, Vanguard, BNP Paribas, Société Générale, Circle and Chainlink. The full service launches in October.

The global market for tokenized real-world assets closed is approaching $40 billion. That is less than three hundredths of 1% of what DTC holds in custody. Everything tokenized worldwide to date fits comfortably within the rounding error on a single depository's balance sheet.

What was tested and why it matters

DTCC ran seven workflows:

• collateral pledging
• securities lending
• delivery versus payment for Treasuries and repo
• delivery versus payment for equities
• delivery versus delivery for equities
• transfers of tokenized equities
• central counterparty margin flows

These are the transactions in which the conventional settlement cycle ties up collateral, forces margins to be oversized and consumes liquidity in transit. We have already looked at how collateral behaves when it can be mobilized without first being converted: the asset no longer travels the full loop from fund to cash to collateral and back to the fund, and it keeps earning a return while pledged.

The transactions ran on two networks in parallel: Hyperledger Besu, which DTCC runs as its private network, and Canton, a public network built for institutional use. DTCC highlights the ability of its tokenized assets to operate across different chains, which is what allows a token created in one place to serve as collateral in another.

What exactly is being tokenized

The details of the architecture determine the scope, and this is where the announcement says more than it seems to.

DTCC tokenizes positions in securities it already holds in custody. Native issuance falls outside the authorized scope, which is limited to Russell 1000 constituents, major index ETFs and US Treasuries. When a participant tokenizes, DTC debits the securities from its account and credits them to a digital omnibus account. Registered ownership stays where it was: in the name of Cede & Co., DTC's nominee, just as before the transaction.

What moves on-chain is the participant's entitlement against the depository. The official record of those tokenized entitlements is LedgerScan, a DTC system that runs off-chain. And participating wallets must be registered with DTC and include controls on distribution and on the reversibility of transactions.

Ownership immobilized in the depository's name, an official record kept off-chain, reversible transactions. Together, these three conditions describe a representation architecture: the token reflects a position whose legal reality still lives in the traditional system.

The Spanish and European framework also allows another route. Under Law 6/2023 and the DLT Pilot Regime, the distributed ledger can serve as the book-entry register of the security, with the on-chain entry having direct legal effect and an entity responsible for recording and registration answerable for keeping it. The instrument is born on-chain and its legal existence lives there.

Each architecture solves a different problem. DTCC's lets trillions already in custody move efficiently without touching the legal structure behind them. Native issuance lets an instrument exist with full legal validity from day one, and opens the primary market to issuers who cannot reach it today. We operate in the second space, and the above is worth reading with that in mind.

That the world's largest custody infrastructure has put representation into production has a practical consequence for everyone else: a de facto standard is starting to take shape for how a tokenized security must behave to be accepted as collateral, and that standard will have to be met from the outside.

Final note

October will show how much of that $114 trillion starts to move this way, and how fast.

For companies seeking financing outside the banking system, the impact is indirect but real: every wholesale flow that becomes routine in tokenized form reduces friction for the next one, and the standard for what a tokenized instrument must meet is being set now, at the tables where collateral eligibility is decided.
