DTCC Tokenization: Collateral Between Participants, Zero at DTC

On July 15, 2026, a U.S. Treasury security tokenized by DTC funded a repo against USDCx on the Canton network, yet that same token is valued at zero as collateral within the DTC settlement system. Both realities are established by the same document: the SEC no-action letter dated December 11, 2025 (a no-action letter is a commitment from the regulator's staff not to recommend enforcement action if the entity operates exactly as described in its request).

DTC is The Depository Trust Company, the subsidiary of DTCC (Depository Trust & Clearing Corporation) that custodies U.S. securities and records ownership; its "participants" are banks and brokers with direct accounts, while the end investor appears only on their broker's books. The letter authorizes these participants to convert Russell 1000 shares (the 1,000 largest U.S. listed companies), index ETFs, and Treasury debt into tokens, move them between their registered wallets, and use them in repos (repurchase agreements: a short-term loan secured by the bond), securities lending, and pledges (delivering the security as collateral for a debt). In the same request, DTC commits not to attribute "any collateral or settlement value" to these tokens in its two intraday risk controls (Collateral Monitor and Net Debit Cap). This article breaks down what the DTC token can already do, what it is prohibited from doing, and what distinguishes it from the Ondo token that a crypto user can actually hold in their wallet.

What is the DTCC Tokenization Service and who can hold its token?

The letter refers to the product as a Tokenized Entitlement: a right to securities recorded with tokens on a chain, rather than an entry in DTC's centralized ledger. The request attached to the letter describes four components. The participant registers one or more addresses on an approved chain (Registered Wallet) with DTC. When a tokenization order is placed, DTC debits the securities from the participant's account and credits them to the Digital Omnibus Account, a centralized ledger account reflecting the sum of all tokenized assets. The Factory system mints the token and delivers it to the registered wallet. Finally, LedgerScan, a DTCC program defined in the request as "off-chain" and hosted "in the public cloud," scans the chains and records which wallet holds each token: "LedgerScan's record would constitute DTC's official books and records."

Registered ownership of the securities does not change at any time: "those securities would remain registered in the name of Cede & Co., DTC's nominee," the entity in whose name DTC registers everything it custodies on the books of each issuer. To prevent double-spending, securities credited to the Digital Omnibus Account cannot leave it until the corresponding token is burned; the token holder cannot move the security by instructing the centralized ledger, only by moving the token or requesting DTC to burn it.

Who can hold the token is strictly defined by representation No. 6 of the request: "The Tokens would only be transferable to Registered Wallets." A participant can open unlimited registered wallets, including for the benefit of their clients, but "DTC would only have a relationship with the Participant itself"; the relationship between the broker and its client is "a bilateral matter." The admitted token protocols must demonstrate "distribution control" (preventing transfer to any non-registered address) and "transaction reversibility" (allowing DTC to force conversion or transfer from its "root wallet"). The letter cites ERC-3643, a token standard with an authorized address list, as an example of a compliant protocol. The DTCC product page, as of September 16, 2026, lists the controls as "mint, burn, pause and clawback."

What can a DTC participant do with the token?

According to the "Token Usage" section of the request, participants and their clients may use the tokens "to engage in the same transactions and activities" they already perform with their book-entry positions: securities financing operations ("repurchase agreements, reverse repurchase agreements, and securities lending transactions"), pledging or transferring ownership "for purposes of obtaining financing or collateralizing transactions," and selling or transferring free of payment (without a cash leg) or against payment. On July 15, 2026, DTCC executed exactly that list in production: collateral pledging, securities lending, Treasury DVP/repo, equity DVP and DVD, token transfers, and margin flows from a central counterparty clearing house. DVP (delivery versus payment) means the security and cash change hands simultaneously or not at all; DVD is delivery versus delivery, security for security.

Why does the SEC no-action letter give the token zero value as collateral for DTC?

DTC settles at the end of the day. During the day, a participant receives securities before paying for them and accumulates an intraday net debt; two controls prevent this debt from jeopardizing settlement. The Collateral Monitor ensures the debt is covered at all times by eligible collateral (securities and cash in the account) and blocks any transaction that would leave it uncovered. The Net Debit Cap sets a ceiling on that debt based on the participant's history and DTC's available liquidity. Note 28 of the request describes both as mechanisms ensuring that "DTC can complete settlement, without systemic disruption, notwithstanding a Participant default."

Representation No. 1 removes tokens from this calculation entirely: "DTC would not ascribe to any Tokenized Entitlements any collateral value or settlement value for purposes of calculating a Participant's Net Debit Cap or the Collateral Monitor." In plain terms: the token does not cover any participant debt to DTC (collateral value) and cannot be used to deliver or receive anything within the DTC settlement engine (settlement value). The operational consequence is stated in the request itself: a participant "could only issue a Tokenization Instruction if it would have been able to instruct DTC to make a free delivery of the Subject Securities." Tokenizing is equivalent to a free-of-payment delivery: securities move from the participant's account to the Digital Omnibus Account and stop counting in the Collateral Monitor. A participant who tokenizes reduces the collateral DTC recognizes, which is why the instruction only proceeds if the remaining collateral still covers their intraday debt. "Neither DTC nor its Participants would be reliant on any Tokenized Entitlements or Subject Securities held in the Digital Omnibus Account to manage a Participant's default."

Between two participants, the token is collateral: Societe Generale describes on the Canton page dedicated to the DTCC service having moved "$10M of tokenized U.S. Treasuries as collateral," and BNP Paribas acted, according to the Canton blog on September 8, 2026, as a lender in an intraday loan of DTC-tokenized securities. Against DTC, the token does not exist as a guarantee: if that participant defaulted, DTC would manage the failure with whatever remains in the traditional account. The letter outlines the path for change. In the "Expansion" section, DTC "would consider [...] allowing Tokenized Entitlements to have settlement or collateral value," and prior to any expansion "would notify the Division staff of its intent to expand [...] and seek relief to the extent necessary." Lifting this condition requires new relief from SEC staff; as of September 16, 2026, none has been recorded, and the DTCC product page still refers to "the standards outlined in the SEC's No-Action Letter."

How was the DTCC repo on Canton paid for on July 15, 2026?

The DTCC note from July 15 lists a "U.S. Treasury/repo delivery-versus-payment (DVP) trade" without specifying the payment method. The letter also does not describe any tokenized cash leg: DTC's new systems (LedgerScan and Factory) can only issue two instructions to the core systems—delivering securities to or from the Digital Omnibus Account and paying cash from a corporate event like a dividend; "all other touch points [...] would be read only." If there was an on-chain DVP, the money had to come from outside DTC.

In at least one transaction, it came from Circle. Temple Digital Group, one of the participants, posted on X on July 15 at 18:41 UTC that it had participated in "one of the first onchain US Treasury repo trades on the Canton Network through the DTCC's tokenization service," and detailed in its July 27, 2026 note that "a tokenized representation of a US Treasury security was financed against tokenized cash (Circle's USDCx) through Temple's RFQ platform," its request-for-quote platform, and that it settled on Canton (the permissioned Digital Asset chain used by banks and custodians) "while the underlying security remained within DTC's existing book-entry framework." The Canton blog on September 8 describes the set as "DVP transactions using Treasuries, equities and ETFs against on-chain cash," without naming the instrument, and places intraday repos at "~15-20 minutes instead of a 1-day minimum." USDCx, according to Circle's December 4, 2025 announcement, is "a dollar-denominated stablecoin created by a decentralized protocol on Canton": by depositing USDC into xReserve, Circle's reserve contract on Ethereum, USDCx is minted on Canton. There was a precedent two weeks earlier: on July 1, 2026, Tradeweb, a fixed-income trading platform, announced that Franklin Templeton had delivered a tokenized Treasury to market maker Virtu Financial "in exchange for USDCx," with Blockdaemon, Digital Asset, and Societe Generale as participants.

The division of roles is as follows: DTC tokenizes the asset leg and maintains the record; the cash leg does not pass through DTC and, in the transaction Temple described, was provided by a Circle stablecoin on the chain where it settled; and the DTC settlement engine continues to see the security parked in the Digital Omnibus Account. Regarding timelines: neither of the two DTCC notes claims a timeframe shorter than T+1 (next-day settlement, the U.S. standard since May 2024); the July 15 note says transactions were executed "over the course of several hours," and the 15-20 minutes is a claim by Canton regarding its repos.

What has been tested and what is missing for the October 2026 DTCC launch?

The timeline organizes what has been done, what has been announced, and what the letter schedules, plus milestones external to DTCC that establish the cash leg and the crypto rail for comparison.

The three-year validity period begins at launch: with an October 2026 launch, the letter expires in October 2029, nearly a year later than if counted from the letter's date. The September 16 note regarding Ondo and Fund/SERV does not affect the securities tokenization service. As of that date, DTCC has not published the October launch note or the final list of approved chains; its product page lists three candidate networks (a private permissioned network based on Hyperledger Besu, Canton, and Stellar) and states that "multiple compatible chains are anticipated to be available at launch later this year." None of the three candidate networks for launch (private Besu, Canton, and Stellar) is the public Ethereum network.

How does the DTC token differ from an Ondo tokenized stock?

The DTC token is most often confused with Ondo Global Markets' stock token (since July 13, 2026, Ondo Stocks). The differences can be summarized in four questions, each supported by the entity's own documentation.

The two cash rails surrounding this table are USDCx, the stablecoin Circle has minted on Canton since December 4, 2025, against USDC deposited in xReserve, and digital money from Fnality, the bank consortium, backed according to its website by central bank funds, with the GBP system operational since December 2023 and the USD system undated. Ondo's $918.91 million is distributed as $593.14 million on Ethereum; $298.53 million on BNB Chain; and $27.23 million on Solana. Compared to the more than $114 trillion ($114 × 10¹²) custodied by DTC, the ratio is 124,060 to 1. However, the difference that determines usage is in the collateral column: the Ondo token is a guarantee against anonymous lenders in a public contract, while the DTC token is a guarantee against another identified participant, with DTC as the registrar capable of reversing the transfer. A client of a participating broker may use a registered wallet if their broker agrees, but in DTC's eyes, the holder remains the broker. Circle and Ondo Finance appear on the July 15 participant list alongside BlackRock, Goldman Sachs, J.P. Morgan, Nasdaq, and the New York Stock Exchange. Regarding how Ondo structures its rights against Securitize and what a buyer of a tokenized stock receives at each window, CleanSky published the comparison of the two tokenized stock models with voting rights and the analysis of xStocks, Ondo, and Robinhood by holder rights. Regarding Fnality and why its USD system has been undated for eleven years, see the piece on the 21-bank consortium and its 2027 stablecoin.

What document would change the verdict on the DTC token?

The verdict is that the DTC token, in the version launching in October 2026, is collateral between participants but not against DTC, and its cash leg does not pass through DTC. Any of these three things would dismantle it, and all three are verifiable in public documents:

1. DTC obtaining an exemption or rule approval that attributes collateral or settlement value to Tokenized Entitlements in the Net Debit Cap or Collateral Monitor. The letter contemplates this as an expansion; if it happens, the token enters DTC's risk engine and competes directly with traditional book-entry.
2. The October launch note allowing token transfers to wallets not belonging to a registered participant. This would break representation No. 6 and place the token in the same market as Ondo.
3. The official record moving from LedgerScan to the chain itself. As long as "LedgerScan's record would constitute DTC's official books and records," the chain is a transport medium and the ledger remains outside.

None of the three has occurred as of September 16, 2026: there is no exemption or rule proposal from DTC regarding tokenization (SR-DTC-2026-002 to -009), the only letter in the Division of Trading and Markets index addressed to DTC is the one from December 11, 2025, and the product page still refers to it. The list of approved chains at launch, which DTC commits to communicating to participants (representation No. 14), is the next dated document: the October launch note, which DTC will accompany with a written notice to the SEC, will establish the chains, initial participants, and whether any of the sixteen representations have changed.
