Merchant Acquiring & Settlement — impact tolerance ≤ 1 business day — ITOL

Impact tolerance: ≤ 1 business day — any missed daily merchant funding deadline; any interruption of authorization forwarding during retail hours (illustrative default — trace the derivation, then replace with your own harm analysis)

Definition: Acquire and settle card transactions for merchant clients, including next-day funding of net settlement to merchant DDA (demand deposit) accounts.

Why it is designated: Merchants depend on predictable daily funding for payroll and vendor payments. Card-brand rules impose funding SLAs (service-level agreements). Extended outages disrupt commerce and, at scale, produce visible retail impact in a bank's regional footprint.
