ESMA tests tokenised collateral against CCP default risks

ESMA opened a call for evidence on 9 October on whether EU central counterparties (CCPs) could use tokenised collateral safely, focusing on whether they can access and turn it into usable funds during a clearing member default. The ESMA announcement invites responses by 15 January 2027; it does not propose a rule change or approve a new collateral class.

The distinction matters because the exercise concerns how assets already eligible as CCP collateral are represented, transferred, managed and realised. ESMA says it is not reassessing or expanding eligible asset categories. Under the existing framework, collateral supports margin and default fund contributions that cover current and potential future losses if a clearing member defaults. It must meet requirements including legal certainty, liquidity, credit quality, valuation and timely realisation.

Which tokenisation models is ESMA examining?

ESMA groups the arrangements into digital twins, natively issued assets and hybrids. In a digital twin model, a token represents or facilitates use of an asset whose authoritative record may remain in a conventional market infrastructure. The underlying holding and token therefore need to stay consistent; ESMA flags the question of which record prevails if they diverge.

In a native model, an asset is issued, held and transferred on a ledger, and collateral processes such as posting and position updates take place there. This removes the separate traditional record layer described in the digital twin model, but makes collateral management depend on the ledger, its control mechanisms and linked settlement processes. A hybrid may combine features of both. ESMA also asks respondents whether its taxonomy reflects current practice and what models it should consider.

The models can interact with tokenised cash, including tokenised central bank money, tokenised deposits or stablecoins, and with other settlement mechanisms. ESMA says tokenised securities could potentially meet initial margin or default fund contribution requirements, while tokenised cash or other settlement assets could support variation margin settlement. It is seeking evidence on how those arrangements work across allocation, mobilisation, posting, ongoing management, substitution and release.

What must happen when a clearing member defaults?

The key operational test is the path from posted collateral to liquidity the CCP can use in default management. With a digital twin, the token may help identify, allocate or pre-position collateral, but the CCP may still need custodial or central securities depository processes to use or dispose of the underlying asset. Reconciliation, confirmation and messaging between the token layer and traditional infrastructure could affect the time required before the asset can be sold, repoed or otherwise realised.

For a native asset, that path may run through on-ledger transfers or sales and connected payment mechanisms. ESMA says the timing and predictability would depend on liquidity availability, settlement mechanisms and reliance on external infrastructure or intermediaries. The call asks stakeholders to describe the steps, bottlenecks and dependencies, including under stress.

What evidence is ESMA seeking before it acts?

The call for evidence paper asks about legal enforceability, segregation and client protection, insolvency treatment, settlement finality, liquidity, haircuts and operational resilience. A ledger entry alone may not establish or transfer ownership rights under national law, the paper says; the legal effect depends on the relevant property, securities and insolvency rules.

ESMA says tokenisation does not remove the underlying legal, credit, market, liquidity or operational risks, and that safeguards for CCP collateral must remain. It says the only central-clearing project it had seen through its CCP supervisory-college work by the paper’s finalisation was HQLAᵡ. The authority will assess responses in the first quarter of 2027, then decide whether regulatory or supervisory action within its remit is appropriate.
