Bank settlement is how financial institutions actually move money to each other after a payment is initiated. Your app may show a transaction as complete in seconds, but behind that display, the sending and receiving banks still have to transfer real funds through reserve accounts held at the Federal Reserve. Those transfers happen across several different systems, each built for a different combination of speed, size, and risk. The Fed sits at the center of the machinery, processing trillions of dollars in interbank transfers every business day.
Clearing and Settlement Are Two Different Steps
Every payment between banks moves through two stages. Clearing is the information stage: your bank transmits the payment details to the receiving bank, both sides verify the amount and the sender’s ability to pay, and the two institutions agree on what’s owed. Think of clearing as the handshake before the money moves.
Settlement is the money-moving stage. The sending bank’s account at the central bank is debited, the receiving bank’s account is credited, and the obligation is discharged. A transaction can clear successfully and still fail to settle if the sending bank doesn’t have enough liquidity when the time comes. Separating the two stages lets the banking system process enormous volumes of instructions while managing the risk of actually transferring value.
Reserve Accounts at the Federal Reserve
Commercial banks don’t settle directly with each other. They hold reserve accounts at the Federal Reserve, and settlement happens by moving balances between those accounts. The Fed debits the sender’s reserve account and credits the receiver’s, creating a centralized ledger where every dollar is tracked. An institution can settle either by maintaining its own master account at a Federal Reserve Bank or by routing through another institution’s account.1Federal Reserve Board. Master Account and Services Database
These accounts operate under Regulation J, which provides the legal framework for the Federal Reserve to collect checks and process fund transfers through both the Fedwire Funds Service and the FedNow Service.2eCFR. 12 CFR Part 210 – Collection of Checks and Other Items by Federal Reserve Banks
Fedwire and Real-Time Gross Settlement
Real-time gross settlement, or RTGS, is exactly what it sounds like. Each payment settles individually, in full, the moment it enters the system. No batching, no netting against other transactions. “Gross” means the entire amount moves in one shot. The Fedwire Funds Service is the primary RTGS system in the United States, and transfers sent through it are immediate, final, and irrevocable once processed.3Federal Reserve Board. Fedwire Funds Services
Fedwire runs on a 22-hour business day, opening at 9:00 p.m. ET and closing at 7:00 p.m. ET the following day.4Federal Reserve Financial Services. Wholesale Services Operating Hours Because each transfer settles the moment the Fed processes it, the receiving bank has the funds almost instantly. That is why Fedwire is the default choice for high-value, time-sensitive transfers where a delay could cascade into larger problems.
Wholesale pricing is lower than most people expect. For 2026, the Fed charges between $0.039 and $0.97 per Fedwire transfer, depending on volume.5Federal Reserve Financial Services. Fedwire Funds Service 2026 Fee Schedules The fee your own bank charges you for a wire is a separate markup set by that institution.
ACH and Deferred Net Settlement
Not every payment needs to settle instantly. The Automated Clearing House network takes the opposite approach. It batches millions of transactions together, calculates the net amount each bank owes the others, and settles only that net balance. If Bank A owes Bank B $5 million across thousands of payroll deposits, and Bank B owes Bank A $3 million in bill payments, only the $2 million difference actually moves through the Fed’s books.6Federal Reserve. Automated Clearinghouse Services
This netting approach fits the payments most people encounter daily: direct-deposit paychecks, utility debits, mortgage payments, tax refunds. The ACH network handled 35.19 billion payments worth $93 trillion in 2025.7Nacha. ACH Network Volume and Value Statistics
Same-Day ACH allows individual transactions up to $1 million each to settle on the business day they’re submitted.8Federal Reserve Bank Services. Same Day ACH Resource Center The Fed processes same-day items across three windows, with transmission deadlines at 10:30 a.m., 2:45 p.m., and 4:45 p.m. ET, and settlement at 1:00 p.m., 5:00 p.m., and 6:00 p.m. ET.9Federal Reserve Financial Services. FedACH Processing Schedule
The trade-off with deferred net settlement is credit exposure. Between the time a payment is submitted and the time net balances actually settle, participating banks carry risk. If a bank fails during the business day, transactions batched within the system face complications. That risk is the reason RTGS exists for large-value payments while ACH handles routine consumer transactions.
CHIPS for Large-Value and Cross-Border Payments
The Clearing House Interbank Payments System, or CHIPS, is a privately operated system that handles large-value payments, particularly cross-border transactions denominated in U.S. dollars. It averaged $2.014 trillion in daily value during 2025.10The Clearing House. CHIPS Delivers Record Value and Resilience for Participants in 2025
CHIPS uses a hybrid settlement model that sits between pure RTGS and pure deferred net settlement. Participants pre-fund a portion of their expected obligations at the start of the day. Throughout the day, payments settle immediately when possible, and when they can’t, an optimization algorithm tries to match them against other queued payments for simultaneous release. Any payments still in the queue at 5:00 p.m. ET go through a final netting cycle, with participants transferring any remaining obligations via Fedwire within 30 minutes.11U.S. Department of the Treasury. FSAP Technical Note – Payment Systems and Liquidity Risk Management Every payment released through the system is final at the moment of release.
FedNow and 24/7 Instant Payments
The FedNow Service is the Federal Reserve’s instant payment system, designed to operate around the clock every day of the year, including weekends and holidays.12Federal Reserve Bank Services. FedNow Service Operating Hours Unlike Fedwire’s 22-hour weekday window, FedNow processes payments continuously. The network has grown to more than 1,600 participants since its 2023 launch.
As of November 2025, the per-transaction limit is $10 million, though individual institutions can set lower limits based on their own risk appetite.13Federal Reserve Financial Services. Customer Credit Transfer and Liquidity Management Transfer Network Limit Increases Fees are low: $0.045 per credit transfer origination in 2026, with the first 2,500 transfers per month discounted to zero as an adoption incentive.14Federal Reserve Financial Services. FedNow Service 2026 Fee Schedule
Eligibility mirrors master account access. Depository institutions, U.S. branches of foreign banks, and certain other organizations that hold a Federal Reserve account can participate. Non-bank entities can act as service providers, initiating and receiving messages on behalf of a participant, but they access the system through a participating bank rather than directly.15Federal Reserve Services. FedNow Service Operating Procedures FedNow also falls under Regulation J, giving it the same legal framework that governs Fedwire transfers.
Intraday Credit Keeps Payments Moving
Banks don’t always have enough in their reserve accounts to cover every outgoing payment the moment it’s sent. On a busy day, a bank might need to send $500 million in Fedwire transfers before its incoming payments arrive. The Federal Reserve addresses this through intraday credit, allowing banks to run temporary negative balances, called daylight overdrafts, during the business day.
Pricing is designed to encourage collateralization. If a bank pledges eligible collateral against its daylight overdraft, the Fed charges no fee. Uncollateralized daylight overdrafts cost 50 basis points on an annualized basis, calculated daily.16Federal Register. Improvements to the Federal Reserve Policy on Payment System Risk Acceptable collateral includes any assets the Fed would accept for discount window lending, as well as in-transit book-entry securities at the Reserve Bank’s discretion.17Federal Reserve. Guide to the Federal Reserve’s Payment System Risk Policy on Intraday Credit
Without intraday credit, banks would either hold enormous idle reserves or strategically delay outgoing payments until incoming funds arrived, creating gridlock across the entire system.
When a Payment Becomes Final
Legal finality is the point at which a payment becomes irrevocable. The sender no longer has any right to the funds, and the receiver has an unconditional claim. Without clear finality rules, every completed payment would remain theoretically reversible.
The Uniform Commercial Code Article 4A provides the legal framework for electronic fund transfers in the United States.18Legal Information Institute. UCC – Article 4A – Funds Transfer Under Article 4A, finality turns on the concept of acceptance. A beneficiary’s bank is deemed to have accepted a payment order at the earliest of several trigger points: when it pays or notifies the beneficiary, when it receives full payment from the sender, or at the opening of the next business day after the payment date if the sender’s order is fully covered by available funds.19Legal Information Institute. UCC 4A-209 – Acceptance of Payment Order
In practice, timing depends on the system. Fedwire transfers become final the instant the Federal Reserve credits the receiving bank’s account. ACH transfers reach finality once the settlement window closes and net balances are confirmed. CHIPS payments are final at the moment of release from the queue. When disputes arise, courts look at these specific timestamps to determine who legally owns the money.
Canceling a Payment Order
The window to cancel is narrow. Under UCC Article 4A, a cancellation request is effective only if it reaches the receiving bank in time for the bank to act on it before accepting the order.20Legal Information Institute. UCC 4A-211 – Cancellation and Amendment of Payment Order Once a bank has accepted the order, cancellation requires the bank’s agreement. You can’t unilaterally pull back a payment the system has already processed.
There are limited exceptions. If the order was unauthorized or resulted from a sender’s mistake, such as a duplicate order, payment to the wrong beneficiary, or an overpayment, the beneficiary’s bank can agree to cancel even after acceptance. The sender bears the costs. Any losses, expenses, and attorney’s fees the bank incurs as a result of the cancellation attempt fall on the sender.
If nobody accepts or cancels a payment order, it expires automatically at the close of the fifth business day after its execution date. The death or legal incapacity of the sender does not automatically revoke a payment order. The receiving bank must actually know about the death or incapacity and have a reasonable opportunity to act before accepting the order.
Why the System Is Built This Way
Settlement risk is the possibility that one side of a transaction delivers payment but never receives what it’s owed in return. The 1974 failure of Bankhaus Herstatt is the standard example: the German bank collapsed after receiving Deutsche marks from counterparties but before sending the corresponding U.S. dollars. Banks that had already paid ended up with unsecured claims in an insolvency proceeding, recovering far less than they were owed after long delays.21Bank for International Settlements. Settlement Risk in Foreign Exchange Markets and CLS Bank
What that failure revealed is that settlement risk can be systemic. When one bank fails to meet its payment obligations, the banks expecting those payments may not be able to meet their own, and the cascading effect can freeze an entire payment network. Every major design choice in modern settlement systems, from RTGS for large-value transfers to pre-funding requirements in CHIPS to collateralization of daylight overdrafts, traces back to that kind of failure.
