How Do Floats Work in Banking: Checks, ACH, Wires, and RTP

Float in banking is the gap between when money leaves one account and when the recipient can actually spend it. During that window the same dollars can show up on both sides of the transaction because one bank hasn’t finished debiting while the other has posted a provisional credit. Federal law caps how long banks can make you wait for most deposits, and the first $275 of a check deposit is generally available the next business day.¹ Understanding the rules matters because the space between “available” and “cleared” is where overdraft fees, check-bounce liability, and common scams live.

Where the Delay Comes From

Three overlapping delays produce what you experience as float.

The first is transit. A paper check sits in the mail or moves through a courier chain. An ACH payment waits for the next batch processing window. Even a wire has a short routing period as messages pass between institutions.

The second is processing. Once your bank has the deposit in hand, it has to log the transaction, verify account numbers, capture the check image, and screen for fraud before initiating collection from the paying bank.

The third is the availability hold itself. Even after internal processing finishes, federal rules give the bank a defined window before it must let you withdraw. Part of the reason is to give the paying bank a chance to reject the item. Stack all three phases together and you get the “my deposit hasn’t cleared yet” experience.

How Long Each Payment Type Floats

Checks

Since the Check Clearing for the 21st Century Act took effect in 2004, banks can capture a digital image of a check at deposit and send the payment information electronically to the paying bank rather than trucking paper across the country.² That collapsed clearing times from days to minutes for the interbank leg. The availability hold your bank places on the deposit is a separate matter, governed by Regulation CC and covered below.

ACH Transfers

Direct deposits, most bill payments, and recurring transfers move through the Automated Clearing House network. ACH is digital but not real-time: your bank collects payment instructions throughout the day, bundles them, and submits them to a central operator at scheduled intervals. Standard ACH settlement takes one to two business days. That is why a payroll file submitted Wednesday can post Friday morning.

Same-Day ACH, available since 2016, compresses that timeline to hours. The system runs three settlement windows each business day, at 1:00 p.m., 5:00 p.m., and 6:00 p.m. Eastern Time, and handles individual payments up to $1 million.³ Miss the last window and the payment rolls to the next business day. Not every bank supports it for every transaction type, and some charge a fee.

Wire Transfers

Domestic wires typically post the same day. International wires add layers. About 90% of SWIFT payments reach the destination bank within an hour, but only about 43% reach the end customer’s account in that same hour.⁴ The gap depends on whether the receiving bank runs 24/7 back-office processing, whether the destination country requires manual compliance review, and time zones. A wire sent from New York at 4:00 p.m. Friday may not post until Monday morning in Asia.

Real-Time Payments

Two networks now settle payments in seconds, around the clock, including weekends and holidays: the Clearing House’s RTP network, operating since 2017, and the Federal Reserve’s FedNow service, launched in July 2023. Both raised their per-transaction ceilings to $10 million in 2025, though individual banks can set lower limits.⁵⁶ On these rails there is no batch, no overnight wait, and no provisional credit that gets reversed later. Whether you can use them depends on whether both your bank and the recipient’s bank have joined at least one network.

Federal Availability Limits

Regulation CC, which implements the Expedited Funds Availability Act, sets the maximum hold periods for different deposit types.¹ Banks can release funds faster, but they can’t hold them longer without an exception. The standard schedule:

Cash deposited in person to a teller: next business day after the banking day of deposit.
Cash deposited at an ATM your bank owns: by the second business day.
Electronic payments such as direct deposit and wire transfers: next business day after receipt.
Government checks, cashier’s checks, and certified checks deposited in person: next business day.
The first $275 of any other check deposit: next business day.⁷
The remainder of local checks: by the second business day.
Deposits at a nonproprietary ATM (one your bank doesn’t own): by the fifth business day.

The dollar figures adjust for inflation every five years. The current thresholds took effect July 1, 2025, and run through June 30, 2030.⁷

Mobile Deposits Are Not Covered by the Same Rules

Regulation CC predates smartphones, and neither the Federal Reserve nor the Consumer Financial Protection Bureau has issued a definitive rule assigning mobile check deposits to a category. A 2024 proposal clarified that mobile deposits aren’t ATM transactions but stopped short of placing them elsewhere. In practice, banks set their own mobile deposit availability policies, and those vary widely. Read your bank’s mobile deposit agreement rather than assuming the standard schedule applies.

When Banks Can Hold Longer

Regulation CC allows extended holds, called exception holds, in specific circumstances. When one applies, the bank must give you written notice stating the amount held, the reason, and the release date.⁸ The triggers:

Check deposits exceeding $6,725 in a single day.⁷
Accounts repeatedly overdrawn in the past six months.
Reasonable doubt about whether the check will be paid.
Redeposited checks that were previously returned unpaid.
Emergency conditions such as natural disasters or communications failures.

How much longer? For local checks that would normally clear in two business days, the bank can add up to five more business days, for a total of seven. For deposits at a nonproprietary ATM, the extension can reach six additional business days beyond the standard five-day hold, pushing the total to eleven. Electronic payments like direct deposit and wire transfers are never subject to exception holds.⁹

New Accounts

An account is considered new for the first 30 calendar days. During that window banks have far more flexibility on check holds. Cash and electronic payments still get standard next-business-day treatment. Government checks, cashier’s checks, and certified checks deposited in a new account get next-day availability on the first $6,725 per banking day, but amounts above that don’t have to be released until the ninth business day.⁸ Regular personal and business checks deposited into a new account aren’t subject to the standard two-day schedule at all. The exception does not apply if you already had another account at the same bank for at least 30 days in the month before opening the new one.

Available Does Not Mean Cleared

This is where people lose real money. When your bank makes deposited funds available, you can spend that amount. It does not mean the check has finished clearing. The credit is provisional. If the paying bank later rejects the check, your bank reverses the deposit, and you owe back every dollar you already spent, often with a returned-item fee added.¹⁰

The paying bank must send notice of rejection within two business days of presentment.¹¹ But that clock starts when the check reaches the paying bank, not when you made the deposit. Factor in transit and processing, and a fraudulent check can bounce a week or more after your bank released the funds.

Scammers work this gap constantly. The classic version: someone sends you a check for more than the agreed amount and asks you to wire back the “overpayment” before it bounces. When the fraud surfaces the wire is gone, and you’re on the hook for the reversed deposit. Treat check proceeds as tentative until you’re confident the paying bank has honored the item, no matter what your available balance shows.

Cut-Offs, Banking Days, and Holidays

Regulation CC uses two terms that sound alike and aren’t. A business day is any Monday through Friday that isn’t a federal holiday. A banking day is any business day your specific bank is open for substantially all of its normal operations, up to its posted cut-off hour.⁹ The availability clock runs off the banking day of deposit, so the cut-off matters. For ATMs and off-site deposit locations, banks can set the cut-off as early as noon. Deposit at 1:00 p.m. on Monday when the cut-off is noon, and the bank treats it as a Tuesday deposit. Every deadline slides a day.

The Federal Reserve System observes eleven holidays per year, and none of those days count as business days for availability purposes.¹² A check deposited on the Wednesday before Thanksgiving with a two-business-day hold won’t clear until the following Monday at the earliest, because Thursday, Friday (if the bank is closed), Saturday, and Sunday don’t count. Deposit the same check on a regular Wednesday and you’d have the funds by Friday. If timing matters for a large deposit, count the calendar days instead of trusting the “two-business-day” label.

If a Bank Holds Your Money Too Long

If a bank extends a hold beyond what Regulation CC allows without a valid exception, it faces civil liability under the Expedited Funds Availability Act. You can sue for actual damages plus an additional penalty between $100 and $1,000. In a class action the total penalty can reach the lesser of $500,000 or 1% of the bank’s net worth, and a successful plaintiff can recover attorney’s fees.¹³

Before filing suit, you can complain to the Consumer Financial Protection Bureau or the Office of the Comptroller of the Currency, depending on the type of institution. Those agencies examine banks for Regulation CC compliance, and a complaint creates a paper trail that can resolve the issue without litigation. If your bank places a hold, ask for the written notice explaining the reason and the release date. Banks are required to provide it, and having the terms in writing makes any dispute far easier to sort out.
