The timing problem
Intraday is the ability to meet obligations as they fall due within the day. A bank can expect more incoming cash than outgoing cash by close and still face a large shortfall at noon. Net daily totals do not describe the order or reliability of those flows.
The Federal Reserve’s Payment System Risk policy governs intraday credit in Reserve Bank accounts. It uses limits, collateral arrangements and fees to control exposure, with a zero fee for collateralized daylight overdrafts under the policy. Eligibility and capacity are institution-specific; this is not unlimited free funding. [1]
Settlement finality changes the control sequence
Fedwire provides settlement in central bank money with finality under its governing terms. Payment approval and fraud checks therefore need to precede release; an investigation request is not a guaranteed undo function. The service disclosure and operating terms should govern precise legal treatment. [2]
Analysis: an institution can manage by sequencing payments, mobilizing collateral and improving receipt forecasting. But delaying its own payments may delay someone else’s receipts, creating network-wide pressure. Optimize customer and settlement obligations as well as the institution’s average overdraft measure.
Worked cash timeline
Hypothetical opening balance is $20 million. At 09:00 the bank pays $60 million, taking the simplified balance to negative $40 million. A noon receipt of $50 million restores it to positive $10 million. The closing result looks comfortable, while the morning requires $40 million of usable intraday capacity.
If the incoming payment is two hours late, the shortfall lasts longer. If a $30 million securities position can support only $27 million after an assumed 10% haircut, it does not cover the full gap. Also check whether that collateral is eligible, already pledged and operationally available in time. These are illustrative values, not actual Federal Reserve margins.
A dashboard for the payment desk
Recommended measures:
Scroll horizontally to see all columns.
| Measure | Decision value | Common mistake |
|---|---|---|
| Peak cumulative outflow | Sizes the timing gap | Using only daily net payments |
| Available collateral value | Tests usable borrowing capacity | Counting face value or double-pledged assets |
| Receipt uncertainty | Supports delayed-inflow stress | Treating expected cash as certain |
| Queued time-critical payments | Measures customer and market impact | Treating every payment as equally deferrable |
| End-of-day contingency | Prevents unresolved overnight exposure | Assuming daylight capacity automatically rolls overnight |
Current collateral context
Federal Reserve Financial Services announced updated collateral margins effective July 1, 2026, including a revised display for loan-collateral margins. The source links to the operative valuation information. A stale haircut table can overstate usable capacity even where the pledged asset balance is unchanged. [3]
Recommended practice is to reconcile treasury’s collateral inventory with the actual borrowing system and test mobilization before stress. A signed contingency line has less value when staff have never drawn it, documentation is incomplete or the collateral file cannot be processed promptly.
Credit relevance and what to test next
Analysis: payment delays can affect loan disbursements, merchant settlement and customer trust. Intraday capacity therefore belongs in product design for faster settlement, not only in a treasury appendix. Price the needed for new promises and identify who can slow or suspend a flow when capacity is constrained.
A useful exercise combines delayed receipts, a provider outage and reduced collateral value. Measure whether critical obligations still settle and whether closing funding is available. Strong average-day performance is insufficient if all fallback paths share one failed provider. Revisit assumptions after changes in payment volume, collateral rules, settlement hours or concentration.
