    TL;DR

    The cash leg matters as much as the asset leg. CBDC, tokenised deposits, and regulated stablecoins each have a distinct settlement-risk profile. The institution choosing among them carries governance obligations that the choice itself does not discharge.

    Quick Read

    Drex went into production in Brazil, the digital euro pilot expanded, the e-CNY corridor with mBridge participants continued, and US institutions continue to settle through GENIUS-licensed payment stablecoins and tokenised deposits. Each path has a different finality model, recovery procedure, and operational-risk profile.

    There is no settlement medium without residual risk. CBDCs concentrate it in central-bank operational continuity. Tokenised deposits concentrate it in issuing-bank resolution. Stablecoins concentrate it in issuer attestation governance. The treasury team's obligation is to know which risk it has bought, not to pretend any path is risk-free.

    The 2026 settlement landscape

    As of April 2026, three settlement models coexist in production for institutional flows. The full status of each programme by jurisdiction is tracked in the CBDC status map. The institutional question is no longer whether tokenised settlement exists. It is which model fits which flow.

    Section · Models

    Three settlement models compared

    01 / 03

    Central-bank CBDC

    Direct central-bank liability. Strongest finality. Concentrated operational dependence on central-bank availability windows.

    DrexDigital Euroe-CNY
    02 / 03

    Tokenised deposit

    Claim on a regulated bank. Deposit insurance and resolution treatment apply. Issuer concentration risk per bank.

    JPMCitiHSBC
    03 / 03

    Regulated stablecoin

    Claim on issuer reserves under a payment-stablecoin licence. 24/7 finality. Issuer attestation governance is the residual risk.

    Treasury-owned obligations under each model

    01

    Finality classification

    Document the legal finality framework of every settlement medium the treasury uses and where it fails over.

    02

    Concentration risk

    Stablecoin issuer, tokenised-deposit bank, and CBDC operational concentration must be measured and limited under treasury policy.

    03

    Sanctions screening

    Sanctions screening applies regardless of settlement rail. Bridge events between rails are the most common screening gap.

    Operational continuity

    Continuity playbooks must cover an outage on each rail in scope, with rehearsed failover to an alternate settlement medium.

    Accounting classification

    Tokenised settlement balances must be classified, fair-valued, and disclosed correctly under IFRS 9 or ASC 326 as applicable.

    Section · ALCO oversight

    What the ALCO should ask

    Q01

    Which settlement media are inside treasury policy for which flow type, and who approves cross-rail substitution under stress?

    Cross-rail substitution authority is the single most common gap surfaced in 2026 stress exercises.

    Q02

    What is the rehearsed failover from a primary CBDC to a regulated stablecoin to a correspondent-bank fallback for the institution's largest daily flow?

    Failover paths that have not been rehearsed are not failover paths.

    Q03

    How is concentration risk on tokenised-deposit issuers measured and limited under the treasury credit limit framework?

    Tokenised deposits do not eliminate single-name exposure to the issuing bank.

    Q04

    Has the institution mapped its sanctions and Travel-Rule obligations across every bridge it uses between rails?

    Bridges are the most common source of Travel-Rule and sanctions findings in 2026 examinations.
