    TL;DR

    The first ninety days of live GENIUS Act attestation prove the licence is necessary and not sufficient. Three run-risk channels remain structurally open: reserve concentration on a small set of qualified custodians, redemption-pathway weekend latency, and bridge-derivative claims outside the issuer's primary attestation perimeter.

    Quick Read

    Issuers licensed under GENIUS now publish monthly reserve attestations under SSAE 18 with stated reserve composition. Counterparties, treasury policy owners, and listing venues are asking three further questions: how concentrated is custodian exposure, can primary-market redemption be honoured at promised tenor on a Friday evening, and what is the disclosure stance on bridged derivatives that trade outside the licensed perimeter.

    A credible stablecoin run-risk posture in 2026 requires four operating evidences: custodian concentration disclosure, weekend-tenor redemption testing, bridge-derivative inventory, and primary-market discount monitoring. The first three are issuer-owned. The fourth is shared with the issuer's largest authorised participants and listing venues.

    Ninety days in: what changed, what did not

    The first ninety days of live GENIUS Act operation moved the stablecoin question from a regulatory-uncertainty story to an operating-evidence story. Reserve composition is now disclosed. The continuous control plane around redemption is still uneven. Issuer-by-issuer status is tracked in the stablecoin issuer tracker; regulatory deltas in the regulatory tracker; and the deeper attestation-stack analysis sits in the companion reserve attestation gap brief.

    What a treasury committee should ask

    Treasury committees holding any material stablecoin balance should ask the questions below of both the issuer and their own custodian. Operating support for stablecoin treasury policy and counterparty diligence is available through Cabier treasury advisory.

    Q01

    Who, on the issuer side, is named to make the weekend-tenor redemption call, and what is the tested escalation path?

    Issuers without a named weekend-tenor owner cannot honour stress redemption at promised tenor.

    Q02

    What concentration exists across qualified custodians, and what is the issuer's documented plan if any single custodian becomes unavailable?

    Custodian concentration is the single largest 2026 deviation finding in counterparty diligence.

    Q03

    How are bridged derivatives of the issuer's token represented to our treasury, and to listing venues we trade on?

    Bridge derivatives outside the attestation perimeter are a recurring 2026 disclosure gap.

    Q04

    What is our internal protocol when the issuer's token trades at a sustained primary-market discount greater than twenty-five basis points?

    Treasury committees that negotiate the action protocol in real time, after the discount opens, transmit the run rather than absorb it.
