Trust & Custody Services — impact tolerance ≤ 1 business day — ITOL

Impact tolerance: ≤ 1 business day — any missed scheduled distribution, corporate-action deadline, or DTCC settlement obligation (illustrative default — trace the derivation, then replace with your own harm analysis)

Definition: Fiduciary account administration, custody of client securities, corporate-trust services, and periodic income/principal distributions. Digital-asset custody is out of scope for the base archetype. The crypto-custody scenario applies only if the bank adds that optional line (OCC IL 1170/1184, SR 22-6 notification).

Why it is designated: Fiduciary duties impose legal standards of care distinct from other banking services. Missed corporate actions (elections, redemptions) can cause direct measurable client harm. A missed corporate-trust distribution exposes the bank to indenture-trustee liability.
