Treasury Liquidity & Funding Operations — impact tolerance ≤ 2 hours — ITOL

Impact tolerance: ≤ 2 hours — during Fedwire operating hours. Any inability to execute a funding draw or monitor the master-account position while time-specific obligations are pending is intolerable. In a deposit-run scenario, the tolerance compresses to the time remaining before the next obligation falls due (illustrative default — trace the derivation, then replace with your own harm analysis)

Definition: Fund the bank itself: monitor the Federal Reserve master-account position and intraday liquidity in real time, execute fed-funds purchases, repo, FHLB (Federal Home Loan Bank) advances, and discount-window draws, and activate the contingency funding plan under stress. Distinct from wire-origination, which moves customer money — this service moves the bank's own balance sheet so that every other payment service remains funded.

Why it is designated: Reg YY requires the archetype to maintain and periodically test a contingency funding plan precisely so that alternative funding sources are "readily available when needed". An untested or unreachable funding desk is itself a compliance failure. The SVB (Silicon Valley Bank) review showed a social-media-era run can demand more cash in hours than legacy planning assumed for days. If treasury cannot see the master-account position or execute a discount-window/FHLB draw inside the Fedwire day, a liquidity squeeze converts into failure. This is the service the register's own deposit-run scenario names as the binding constraint.
