    TL;DR

    Whether a tokenised asset survives a custodian or issuer failure is determined by custody structure, not by the tokenisation rail. The four perimeters that matter, in order, are segregation, qualification, rehypothecation, and resolution-framework alignment.

    Quick Read

    The CLARITY Act introduced the qualified digital asset custodian. SIPC, FDIC, and equivalent international protections continue to apply by structure rather than by token wrapper. The investor protection question on a tokenised T-bill or tokenised real-estate share is, in 2026, the same question that applied to the analogue equivalent.

    The four custody perimeters are segregation, qualification, rehypothecation, and resolution alignment. A tokenised asset that crosses any one of these perimeters carries the same investor-protection profile as the analogue equivalent that crosses it. Tokenisation is neither a protection nor a risk multiplier on this dimension, but it makes the perimeter crossings faster and harder to reverse.

    Four custody perimeters that matter

    For an extended legal walk-through of what custody structure means in a bail-in event, see the companion article on bail-ins and broker risk. The four perimeters below are the actionable summary.

    01

    Segregation

    Is the client position recorded in a segregated account with bankruptcy-remote treatment, or in an omnibus structure where the client is a general claimant?

    Rule 15c3-3CASS
    02

    Qualification

    Is the custodian a qualified custodian under CLARITY, the Investment Advisers Act Custody Rule, or the equivalent foreign regime?

    IAA Rule 206(4)-2CLARITY
    03

    Rehypothecation

    Has the client consented, expressly or by margin-agreement default, to rehypothecation of the tokenised position?

    Reg TMargin agreement
    04

    Resolution alignment

    Does the custodian's home resolution authority recognise the client's tokenised claim and ring-fence it in a wind-down?

    Where each perimeter sits in the stack

    L1

    Network finality

    Tokenisation rail

    Determines when the transfer is irrevocable on the ledger. Does not determine ownership in bankruptcy.

    L2

    Custody bookkeeping

    Qualified custodian

    Determines whether the position is recorded as segregated or omnibus, and whether the custodian is qualified.

    L3

    Investor agreement

    Account opening documents

    Determines whether rehypothecation consent applies and what protections the investor has bargained for.

    L4

    Investor-side governance

    Investor-owned control plane

    Tracks all of the above continuously, including any post-trade movement between custody structures.

    Section · Investor-owned

    Investor-side obligations

    01

    Document the custody structure

    On a per-position basis, document segregation status, custodian qualification, and any rehypothecation consent.

    02

    Monitor structural drift

    Custody structure can change post-trade through margin events or substitution. Continuous monitoring is required.

    03

    Test the claim pathway

    The investor must be able to identify, on demand, who they would file a claim with in a custodian failure and on what evidence.

    Section · Investment committee

    What an investment committee should ask

    Q01

    For each tokenised position, can we produce within one business day the custody structure, qualified-custodian status, and rehypothecation consent state?

    If the answer is no, the committee is operating without custody-perimeter visibility.

    Q02

    Have we modelled the recovery pathway under a qualified-digital-asset-custodian failure scenario, including time to access?

    Tokenisation can accelerate market events without accelerating resolution-process timelines.

    Q03

    Are bridged versions of our positions inside or outside the original custody perimeter?

    Bridges typically reset the custody analysis. Many holders are unaware of which perimeter applies post-bridge.
