A wire transfer is an electronic payment that moves money from one bank or financial institution to another through a dedicated interbank network. No cash or paper changes hands. The sending bank transmits payment instructions (who gets paid, at which bank, into which account and how much), and the receiving bank credits the recipient. Wires can be domestic, between two institutions in the same country, or international, crossing borders and often currencies. People call them a bank wire, a wire payment or simply “wiring money.”

How a Wire Transfer Works

Information needed for a wire transfer

Before a bank will send a wire, the sender typically has to provide:

• Recipient details: full name, address and sometimes a phone number, matching how the account is titled.
• Recipient’s account information: the account number, and for some banks a branch number.
• Receiving bank details: the institution’s name and address and its identifier. In the U.S. that is the ABA routing number for domestic wires. Internationally it is the SWIFT/BIC code, and in many countries an IBAN for the account.
• Amount and currency.
• Purpose of the transfer: banks often ask for the reason, especially for international payments.

Some recipients, including businesses and an LLC receiving client payments, publish a sheet of “wire instructions” with these fields so payers can enter them correctly.

The wire transfer process, step by step

1. Initiation. The sender requests the wire at a branch, online or by phone. The bank verifies identity and confirms the account has sufficient funds.
2. Debit and fee. The bank removes the amount and its outgoing wire fee from the sender’s account, so the sender pays upfront.
3. Message transmission. The sending bank transmits payment instructions over a secure network. Domestic U.S. wires typically run on Fedwire, operated by the Federal Reserve. International instructions usually travel as SWIFT messages.
4. Crediting the recipient. The receiving bank checks the details and deposits funds into the named account. A wire that settles on Fedwire is final once processed. Fedwire is a real-time gross settlement system: each payment settles individually, as it happens, in central bank money.
5. Interbank settlement. For payments routed through correspondent banks, the institutions settle balances between their accounts, sometimes after the recipient has already been credited.

Two terms are often confused here. SWIFT is a messaging network, not a payment system. It carries the instructions, while the money itself moves through accounts that banks hold with each other (correspondent accounts). Fedwire, by contrast, both carries the instruction and settles the funds. CHIPS, a privately operated U.S. system for large-value dollar payments, is another network banks use.

Non-bank wire services

Money transfer companies also send “wires,” and these do not always require a bank account on either end. Western Union is the best-known example: its international money transfer service reaches more than 200 countries, and recipients can often collect cash at an agent location. These services work differently from a bank-to-bank wire, but the sender still pays upfront and the recipient receives a specific amount.

Domestic and International Wire Transfers

Domestic wire transfers

A domestic wire moves money between two institutions in the same country. In the U.S., the sender needs the recipient’s routing number and account number. Because Fedwire settles in real time during its operating hours, domestic wires often arrive within hours.

International wire transfers

An international wire starts in one country and lands in another. The sender needs the receiving bank’s SWIFT/BIC code and the account details the destination country uses. The extra time comes from the routing. If the sending and receiving banks have no direct relationship, the payment passes through one or more intermediary (correspondent) banks, and each hop can add processing time, compliance checks and sometimes a fee. Currency conversion is another step. Either the sending bank converts the money before it leaves, or the payment travels in the original currency and is converted on arrival.

A transfer between accounts at the same banking group in two different countries is still an international wire. It has to be initiated as a cross-border payment.

How Long Does a Wire Transfer Take?

In rare cases, errors such as a misspelled name or a wrong account number, or compliance holds, have stretched delays to as long as three weeks. Wires generally do not move on weekends or bank holidays, so a Friday afternoon international wire may not arrive until midweek.

Once a wire is credited, the money is usually available to the recipient immediately. Banks typically do not place holds on incoming wires the way they might on a deposited check.

Wire Transfer Fees

Banks charge for wires because each one is handled individually. The payment is sent and settled on its own rather than batched with thousands of others, it carries compliance screening, and it uses a network the bank pays to access. Fees are usually flat, not a percentage.

Commonly reported ranges:

• Outgoing domestic: about $15 to $35, sometimes more
• Incoming: up to about $20, and some receiving banks deduct this from the amount credited
• Outgoing international: often higher than domestic
• Intermediary bank fees: possible on international wires, deducted from the amount in transit
• Currency conversion: an exchange rate markup built into the rate, separate from any stated fee

Fees vary by bank and account tier, and some premium accounts waive them. Some banks also set daily or per-transaction wire limits.

Example of a Wire Transfer

Hypothetical example 1: a domestic wire. Maria is buying a used car from a private seller and needs to send $8,000. Assume her bank charges $30 for an outgoing domestic wire and the seller’s bank charges $15 for incoming wires.

• Maria’s account is debited: $8,000 + $30 = $8,030
• The seller’s bank receives $8,000 and deducts its fee: $8,000 − $15 = $7,985 credited
• Total fees: $45, or about 0.56% of the transfer

Hypothetical example 2: why flat fees punish small wires. The same $30 outgoing fee on a $100 wire is 30% of the amount sent. On $50,000 it is 0.06%. Wires make economic sense mostly for larger amounts, where the flat fee is small relative to the payment.

Hypothetical example 3: an international wire. A small U.S. business pays a supplier €10,000. Assume the bank’s outgoing international fee is $45, the bank’s exchange rate is 1.12 dollars per euro while the mid-market rate is 1.09, and one intermediary bank deducts €20 in transit.

• Cost in dollars at the bank’s rate: €10,000 × 1.12 = $11,200
• At the mid-market rate it would have been €10,000 × 1.09 = $10,900, so the conversion markup costs $300
• Business pays: $11,200 + $45 = $11,245
• Supplier receives: €10,000 − €20 = €9,980, before any incoming fee at the supplier’s bank

The visible fee is $45, but the exchange rate markup costs more than six times that. Because of the intermediary deduction, the supplier also receives less than the invoice. Many international wire forms let the sender choose who pays the charges, which determines whether the recipient gets the full amount.

How Safe Are Wire Transfers?

The banking side of a wire is secure. Legitimate wire services verify the identity of the parties, which makes anonymous transfers impossible. Instructions travel over closed, authenticated networks. The weak point is the person being paid.

Finality cuts both ways

A wire cannot bounce, and the recipient can treat the money as received. The same finality means that once a wire is sent to the wrong person, the sending bank can request a recall, but recovery depends on the receiving bank and the recipient cooperating. There is no chargeback process like the one card payments offer. If you suspect fraud, contact your bank immediately, because the chance of recovery drops quickly. For consumers sending international remittances from the U.S., federal rules (the Remittance Transfer Rule under Regulation E) generally allow cancellation within 30 minutes of payment and require disclosure of fees and exchange rates. Domestic wires do not have an equivalent cancellation right.

Common wire fraud patterns

• Impersonation: a scammer poses as a relative, a government agency, a romance interest or tech support and asks for an urgent wire.
• Changed payment instructions: a fraudster who has accessed or spoofed an email account sends “updated” wire details for an invoice or a real estate closing. Large sums often move by wire when closing on a mortgage, which makes home purchases a frequent target.
• Overpayment scams: the victim receives a check that later bounces and is asked to wire back the “excess.”

A practical safeguard is to confirm wire instructions by phone, using a number you already know rather than one in the email, before sending.

Government monitoring

International wires that originate in the U.S. are screened against sanctions programs administered by the Treasury Department’s Office of Foreign Assets Control (OFAC). The goal is to stop funds from reaching terrorist financing, money laundering or sanctioned countries and persons. Banks must block or reject transfers that violate sanctions. Payments can be flagged when they involve:

• A sanctioned individual or entity
• A sanctioned country, as origin or destination
• Non-sanctioned parties believed to be acting for or connected to sanctioned parties
• Activity with no apparent legitimate purpose

A flagged wire can be delayed or frozen while it is reviewed, which is one reason international wires sometimes take longer than expected.

Wire Transfers vs. Other Ways to Send Money

Many people use “bank transfer” for any account-to-account payment, but the methods differ in speed, cost and reversibility.

ACH transfers. The Automated Clearing House network, governed by Nacha, processes payments in batches. It handles direct deposit payroll, bill payments, tax refunds and many one-time transfers. ACH is usually cheap or free but slower, and some ACH entries can be returned or disputed in ways a wire cannot.

Instant payment systems. In the U.S., the RTP network and the Federal Reserve’s FedNow service (launched in 2023) settle individual payments in seconds, around the clock, at participating banks. They target everyday payments, while wires remain the standard for high-value transfers and international payments.

Peer-to-peer apps. Services such as Zelle, Venmo and PayPal let users send money with an email address or phone number instead of banking details, often for low or no fees on domestic transfers. They suit small amounts between people who know each other. App limits are usually far lower than wire limits, and buyer protections vary by service and payment type.

Checks and money orders. Mail can be lost or delayed, and a check can bounce after the recipient has acted on it. A cashier’s check is drawn on the bank itself, which reduces that risk, but it still has to be delivered physically.

FAQs

The Bottom Line

Wire transfers suit people moving large or time-sensitive sums, such as a home closing, a private car sale or a payment to an overseas supplier. Flat fees make them poor value for small amounts, where ACH or payment apps cost less. Because a sent wire is final and hard to recover, confirm the instructions by phone using a number you already know before sending.
