Bank proposes rules for tokenised collateral

The Bank of England is consulting on supervisory expectations for financial clearing houses that want to accept tokenised assets as collateral, creating a potential route for digital forms of existing securities to become more widely used in wholesale financial markets.

The proposals focus on central counterparties, or CCPs, which stand between buyers and sellers in cleared transactions and manage the financial risks arising if a market participant fails to meet its obligations.

Clearing houses require members to provide collateral that can be used to cover potential losses. Government bonds, cash, and other eligible assets can fulfil that function, provided they meet standards governing liquidity, valuation, and the ability to realise their value when required.

Tokenisation involves representing ownership or rights associated with an asset through digital records, potentially using distributed ledger technology. A tokenised security may represent an existing financial instrument while allowing ownership or transfer information to be maintained through different technical infrastructure.

The Bank considers that the existing regulatory framework can accommodate tokenised versions of eligible collateral without requiring a separate set of rules for the technology itself. Its proposed supervisory statement would explain how clearing houses should assess those arrangements before accepting them.

Tokenised government bonds are a principal example because conventional government securities are already widely used as collateral in central clearing. Their digital equivalents could potentially enable faster movement between institutions and more efficient responses to margin calls.

A margin call requires a clearing member to provide additional collateral when its risk exposure increases. The ability to transfer suitable assets more quickly could help firms meet those demands while reducing operational delays associated with conventional settlement arrangements.

However, the Bank’s proposed framework places equal emphasis on the reliability of those systems under financial stress. A digital representation of an asset must remain capable of being valued, transferred, and realised even when market conditions deteriorate.

The consultation identifies several areas requiring assessment, including liquidity, interoperability, settlement finality, credit exposure, concentration risk, operational resilience, custody, and safeguarding.

Interoperability concerns how digital asset platforms connect with existing settlement systems and other financial infrastructure. Where a clearing house needs to realise collateral rapidly, technical incompatibility could impede a transaction even when the underlying asset remains valuable.

Settlement finality raises a different question: the point at which an asset transfer becomes legally effective and cannot be reversed. Clearing houses need certainty about those rights when managing a member’s default.

Custody and safeguarding arrangements must also establish who controls the asset, how ownership can be demonstrated, and whether the clearing house can enforce its rights if an intermediary fails. These considerations become particularly important where a token is linked to securities held elsewhere.

The proposed supervisory expectations do not automatically authorise every type of digital asset. The Bank is concentrating on tokenised forms of collateral already eligible under the relevant clearing framework, while inviting views on whether its approach could be extended to additional asset types in the future.

Clearing houses seeking to introduce new collateral arrangements must continue to follow the applicable regulatory approval processes and demonstrate that risks can be managed within their existing governance and financial resilience frameworks.

The consultation forms part of wider work with HM Treasury, the Financial Conduct Authority, and industry participants to support the development of digital wholesale financial markets.

Responses are invited until 12 February 2027. The resulting supervisory approach will provide further guidance on how clearing houses can assess tokenised collateral while maintaining the safeguards required of existing financial market infrastructure.
