Waiting on liquidity: a Fedwire payment short of Reserve funds
Trigger: Bank Alfa's account at the Federal Reserve does not hold enough to cover a high-value Fedwire payment when the message arrives.
What operations sees first: A high-value wire does not settle immediately; it waits until the Reserve account is funded.
WHERE IS THE MONEY?
Debited from the originator; the beneficiary is paid only once the sending bank funds settlement.
DID SETTLEMENT HAPPEN?
Settlement waited on liquidity — the payment did not settle until the Reserve account was covered.
WHO ACTS NEXT?
Bank Alfa (sending bank) Bank Alfa manages its intraday liquidity so high-value wires do not stall late in the day.

The originator requests a wire
Originator (payer) → Bank Alfa (sending bank)

- 02ProcessingBank Alfa validates and screensBank Alfa (sending bank)
Format checks, sanctions screening, and a balance check on the customer run before the bank commits value to an irrevocable rail.
Screening checkpoint: Outbound screening — A Fedwire payment is final once settled, so screening happens before the message is released.
- 03PostingBank Alfa debits the originatorBank Alfa (sending bank)
The customer's account is reduced. The money has left the originator, but the receiving bank does not have it yet.
- DR Originator's account at Bank Alfa — USD 5,000,000.00
- 06 · EXCEPTION PATHProcessingBank Alfa funds its Reserve accountBank Alfa (sending bank)
The bank brings in incoming payments or moves liquidity so its Reserve account can cover the outgoing transfer.
- 07 · EXCEPTION PATHSettlementThe funded transfer settlesBank Alfa (sending bank) → Cassia Bank (receiving bank)
With cover in place, the Federal Reserve settles the payment across the two Reserve accounts, finally.
- DR Bank Alfa's account at the Federal Reserve — USD 5,000,000.00
- CR Cassia's account at the Federal Reserve — USD 5,000,000.00
- OUTCOME

- Debited from the originator; the beneficiary is paid only once the sending bank funds settlement.

THE TIMELINE
- 01Bank Alfa (sending bank)Submits a USD 5,000,000.00 Fedwire payment, but its Federal Reserve account balance will not cover it.
- 02Fedwire (Federal Reserve)Does not settle an unfunded payment; the wire is pending until the Reserve account holds enough.
- 03Bank AlfaReceives incoming wires or funds the account so its Reserve balance can cover the payment.
- 04Federal ReserveSettles the payment gross in central bank money the instant the account is covered, final and irrevocable.
Resolution: Fedwire is RTGS: it settles a payment only when the Reserve account can cover it. The payment waits on liquidity rather than failing, then settles with finality.
