Tokenized collateral: moving a pledge in minutes

Collateral is rarely short in the system; it is in the wrong place. A firm can hold eligible bonds in one custodian and owe margin in another currency at another clearing house on the same afternoon, and the limit is how fast the pledge can get from one to the other.

The conventional path runs through custodians, settlement agents and correspondents, and each leg costs hours. Firms absorb that by holding cash, which earns less than the securities it replaces. Tokenizing the position attacks the delay instead of the shortage: J.P. Morgan describes its Kinexys Tokenized Collateral Network as transferring collateral ownership without moving assets in the underlying ledgers, which is exactly the separation that saves the time. Chainlink makes the same point in capital terms, since an asset that can be mobilized the same day supports more activity than one that cannot.

The first asset tokenized for this purpose was the money market fund share, and the reason is that it solves a specific annoyance. A firm that needs cash for margin sells fund shares, waits for the redemption, posts the cash and loses the yield. A tokenized share can be pledged directly, so the holder keeps the fund yield and still meets the margin call.

US Treasuries, treasury bills and cash deposits followed as the other named candidates, and they share the property that makes them work here: a clearing house or a counterparty already accepts the underlying, so only the transfer mechanism is new. Tokenized money market funds covers the instrument itself, and tokenized assets the wider class.

Atomic settlement means both legs of an exchange happen in one indivisible step, or neither happens. On a shared ledger the collateral token and the payment move in the same transaction, so there is no window in which one side has delivered and the other has not.

What that removes is the principal risk inside the window. In conventional settlement the exposure between delivery and payment is managed with credit limits, a central counterparty or simply a trusted relationship, and all three cost money. Atomic DvP also enables intraday terms that are impractical today, such as a repo for hours instead of days, because the operational cost of opening and closing the position no longer dominates the interest earned. On-chain capital markets sets out the same mechanism on the securities side.

Netting and margin between two institutions run on standard documentation, and that documentation had to be told what a token is before anyone could post one.

ISDA published model provisions for the variation margin credit support annex in December 2023, introducing the defined terms DLT Cash for stablecoins and DLT Securities for tokenized securities, and followed with a guidance note on validity and enforceability. The effect is that a tokenized asset can be named as eligible collateral in the same annex that lists bonds and cash, with transfer and valuation mechanics that reference the ledger. Without that step each pair of counterparties would negotiate the point from scratch, which is why the documentation mattered more than the technology.

German security interests are formal, and the form depends on what the token legally is. Where the token is an electronic security under the Electronic Securities Act, the eWpG, the entry in the register is the security itself, and a pledge is created by entry in that register, which gives a clean answer. Issuing tokenized securities in Germany sets out the register types.

Where the token is only a representation of an asset held elsewhere, the pledge has to attach to that underlying claim under the Civil Code, and the token transfer is evidence of the pledge instead of the pledge itself. A transfer of a crypto-asset by way of security, the Sicherungsübereignung route, is the third construction and the one most used for a coin. The practical rule for a documentation lawyer is to identify the legal object before choosing the security form, because a pledge taken over the wrong object is unenforceable exactly when it is needed.

Today, in general, not tokens. Central counterparties publish eligible collateral lists, and those lists name conventional cash and securities with the haircuts that apply, which means a cleared derivative cannot be margined with a tokenized asset at most CCPs. The bilateral market moved first because two counterparties can agree between themselves what the documentation allows.

Two other approvals sit behind the CCP question. Prudential treatment decides how much capital a bank holds against a tokenized position, and the Basel standards for crypto-asset exposures are still being settled, so a bank may find the same asset more expensive in tokenized form. In the EU the DLT Pilot Regime, Regulation (EU) 2022/858, gives market infrastructures a route to operate with exemptions and is the sandbox where this is being tested, alongside the MiCA framework for the crypto-asset side.

Three uses lead, and they are the ones where the delay costs the most. Repo comes first, since a repo is a collateral transfer by definition and an intraday repo is impossible without fast settlement. Variation margin on uncleared derivatives comes second, because the documentation now supports it and the daily call is where the cash buffer sits. Securities lending comes third.

The constraint in all three is the same: a token is only useful as collateral if the counterparty can receive it on a platform it already uses, and firms report that moving a token between platforms is the part that does not work yet. That fragmentation, not the law, is what keeps the volumes small while the pilots succeed.
