FedNow: instant settlement at the Federal Reserve

Your notes

What this means in plain language

The Federal Reserve's FedNow Service settles each retail payment individually and irrevocably in central-bank money, around the clock, so the receiver can use the money in seconds — a real-time gross settlement rail that contrasts with batch, deferred-net ACH.

Understand the full idea, step by step

Send someone money on a Sunday afternoon in the United States and, on most rails, the money does not really move until a bank business day later — the notification is instant, but the settlement waits. The FedNow Service breaks that habit. It is the Federal Reserve's own instant rail, and it settles each payment there and then, in the central bank's own money, at any hour of any day. What makes that possible is worth taking slowly, because it is a different machine from the batch systems most people grew up with.

Individually, immediately, and finally

The FedNow Service is the United States instant-payments rail operated by the Federal Reserve. Its defining trait is how it settles: each accepted payment is settled on its own, the instant it is accepted, and irrevocably — one payment at a time, with no waiting for others to be gathered up. Settlement happens in central-bank money, by debiting the sending bank's balance in its Federal Reserve master account and crediting the receiving bank's. Because the Federal Reserve is both the operator and the place where the banks hold their money, there is no separate settlement agent to wait on and nothing left owing between the banks once a payment is done. And it runs 24 hours a day, every day of the year — there is no cut-off, no overnight window, no closing for the weekend.

Real-time gross settlement (RTGS)each payment is settled on its own, in full, as it is accepted

Gross means one payment at a time, for its full amount — the opposite of netting many payments down to a single figure. Real-time means it happens the moment the payment is accepted, not at a scheduled cycle. Put together, RTGS is a system that settles accepted instructions individually and immediately across accounts at the central bank. FedNow is an RTGS system that happens to run around the clock at retail speed; the same settlement discipline underlies the large-value systems central banks have run for decades.

Settlement finalityonce settled, the payment is done and cannot be pulled back

When the Federal Reserve moves the value between the two master accounts, that movement is final: it will not be reversed or unwound. This is why the order of events matters on an instant rail. Screening and the receiving bank's confirmation both happen before settlement, because there is no later batch window in which to catch a problem. Finality is also what lets Arjun spend the money at once — Nordbank is crediting him against value it already holds for good, not against a promise that might still fall through.

You may be wondering: if the money moves in seconds, where does the sending bank get it from — does the Federal Reserve extend credit for each payment?

No. Each bank keeps a balance — a prefunded balance — in its master account at the Federal Reserve, and an outgoing FedNow payment settles against that balance. If Bank Alfa has not funded enough to cover USD 300.00 at the moment the payment arrives, the payment is rejected rather than settled; an RTGS system does not create money a bank has not put up. That is the trade for finality and speed: the sending bank must hold value in advance, so the receiving bank is never left waiting on funds that were never there. Managing that balance around the clock is part of running on an instant rail that never closes.

Riya's USD 300.00 over FedNow

  1. INSTRUCTION

    Riya asks Bank Alfa to send USD 300.00 to Arjun. FedNow runs 24/7/365, so there is no cut-off — but nothing has moved yet, this is only a request.

  2. VALIDATION

    Bank Alfa validates the payment, screens it for sanctions in real time, and confirms it holds enough prefunded balance in its Federal Reserve master account. These checks must finish in seconds.

  3. MESSAGE

    Bank Alfa submits the payment message to the FedNow Service, which processes it the instant it arrives. The message asks for settlement; it does not itself carry the money.

  4. MESSAGE

    FedNow asks Nordbank whether it can credit Arjun. Nordbank checks the account and answers positively — this confirmation is what lets settlement proceed.

  5. SETTLEMENT

    The Federal Reserve debits Bank Alfa's master account and credits Nordbank's for this one payment, in central-bank money. The settlement is immediate, gross, and final.

  6. LEDGER

    With the interbank leg settled, Bank Alfa books the final debit against Riya's account and Nordbank credits Arjun, who can spend within seconds — even on a holiday.

COMMON CONFUSION

FedNow is just a faster version of ACH — the same batch machinery, sped up to run more often.

They are different machines. ACH is a batch, deferred-net system: it gathers many payments, nets what banks owe each other down to a smaller figure, and settles that net amount at scheduled times on business days. FedNow settles each payment individually and finally the moment it is accepted, in central-bank money, at any hour of any day. One defers and nets; the other settles gross in real time. Speeding up batches would never give you per-payment finality on a holiday.

STRICTLY SPEAKING

Strictly speaking, real FedNow operation involves more than a single payment settling: banks manage liquidity in their master accounts across the day, there are participant onboarding rules and operational limits, and exception handling for rejected or returned payments. The durable lesson is the settlement model — individual, immediate, final settlement in central-bank money, around the clock — which is what separates an instant RTGS rail from a batch one.

FOR NOW, REMEMBER

  • The FedNow Service is the United States instant-payments rail, operated by the Federal Reserve and running 24 hours a day, every day of the year.
  • It settles each payment individually, immediately, and irrevocably — real-time gross settlement — rather than batching and netting.
  • Settlement is in central-bank money, against the sending bank's prefunded balance in its Federal Reserve master account, so there is no unsettled credit risk between the banks.
  • The message asks for settlement and carries no money; screening and the receiver's confirmation come before settlement, because finality leaves no later window to catch a problem.
  • Contrast with ACH, a batch, deferred-net system that clears payments and settles the net amount later on business days.

TRY IT YOURSELF

Riya sends USD 300.00 to Arjun over FedNow on a public holiday, and seconds later Arjun's bank shows the money as spendable. A colleague says this can only mean FedNow held the payment and settled it net with other payments once banks reopened. What is the accurate correction?

FedNow settled Riya's USD 300.00 on its own, immediately and finally, across the two banks' master accounts at the Federal Reserve — real-time gross settlement, with no batching, no netting, and no waiting for a business day.

Correct — Correct. FedNow is an RTGS instant rail: each accepted payment settles individually in central-bank money the moment it is accepted, which is exactly why Arjun could spend the money on a holiday rather than after the next settlement cycle.

The colleague is right — FedNow shows the money instantly for the customer but actually nets and settles between banks on the next business day, like ACH.

Not this one — That describes a deferred-net batch system such as ACH, not FedNow. Over FedNow the interbank settlement is final at the same moment Arjun is credited; there is no deferred net leg waiting for a business day.

It can only work because the Federal Reserve extended Bank Alfa credit for the USD 300.00 and will collect it later.

Not this one — FedNow settles against Bank Alfa's own prefunded balance in its master account, not against Fed credit. If that balance did not cover the amount, the payment would be rejected rather than settled — the system does not create unfunded value.

FedNow settles each payment gross and now; ACH clears many and settles the net later. That split — real-time gross settlement versus deferred-net settlement — is the fork that shapes almost every payment system, and it is worth seeing side by side.

KEEP GOING

Three things to remember

  1. 01

    Identify who instructs, processes, clears, settles, and ultimately receives the funds.

  2. 02

    Keep the exchange of payment information separate from the movement of money.

  3. 03

    Trace where validation, accounting, charges, and exceptions enter the journey.

Settlement risk and CLS

Settlement risk is the danger that one side of a trade completes while the other fails. In foreign exchange this is Herstatt, or principal, risk — reduced by settlement finality, payment-versus-payment, and the CLS system.
