An international money transfer works by sending a payment instruction, not cash, across a global bank messaging network called SWIFT. Your bank transmits a standardized message to the recipient’s bank describing who is paying whom, in what currency, and for what purpose. If the two banks don’t have a direct relationship, the message passes through one or more correspondent banks that do. At each step, banks adjust balances they hold with each other, and when the message reaches the destination, the recipient’s bank credits the account. Understanding how international money transfers work means understanding three things: the chain of banks the message travels through, the fees and exchange-rate markup each leg adds, and the compliance checks that can delay or stop the payment.
What Happens When You Hit Send
SWIFT, the Society for Worldwide Interbank Financial Telecommunication, connects more than 11,000 financial institutions. It does not hold or move money. It operates the secure messaging system banks use to tell each other to pay someone. When you initiate a wire, your bank sends a SWIFT message identifying the sender, the recipient, the amount, and the currency.
Each institution on the network has a Business Identifier Code, or BIC, which is the eight-character code identifying the bank and country, or eleven characters when a specific branch is named.1Swift. Business Identifier Code (BIC) You may see this called a SWIFT code; it’s the same thing.
Most banks don’t maintain accounts with every other bank in the world. To bridge the gap, they use correspondent banking. A correspondent is a large institution, such as JPMorgan Chase or Deutsche Bank, that holds accounts on behalf of smaller banks in various currencies. If your U.S. bank has a direct correspondent relationship with the German bank receiving the money, the payment travels one hop. If not, the message routes through one or more intermediaries that do have the right connections. Each intermediary processes the instruction and passes it on. No physical currency crosses a border at any point. Banks debit one ledger entry, credit another, and the next bank in the chain does the same.
Every bank in the chain is a potential point of delay and a potential point of fees. That single fact explains most of what follows.
Information You Need Before You Can Send
Getting the recipient’s details exactly right is the single most important step. A wrong digit in an account number can send money to the wrong person, and recovering a misdirected wire is difficult and sometimes impossible. Your bank will ask for:
- The recipient’s full legal name, matching the name on the account at the receiving bank.
- The recipient’s physical address.
- The BIC/SWIFT code of the recipient’s bank.
- The account number, or, in Europe, much of the Middle East, and parts of Asia and the Caribbean, an International Bank Account Number (IBAN). An IBAN can run up to 34 characters and encodes the country, two check digits, and the underlying bank and account number.
- A short description of the purpose of payment: tuition, family support, invoice, and so on.
The purpose-of-payment field is not optional paperwork. Under the federal Travel Rule, financial institutions must collect and pass along identifying information about both parties for any funds transfer of $3,000 or more.2eCFR. 31 CFR 1010.410 – Records to Be Made and Retained by Financial Institutions If a compliance team cannot determine the purpose and legitimacy of the transaction, the bank can refuse the transfer entirely.
You can find your own IBAN and BIC on your bank statement, inside your online banking portal, or by asking your bank. When the recipient gives you their details, read every character back to confirm. Typos in wire instructions are the most common source of delay.
How Long International Transfers Take
The common estimate is one to three business days. The real range is wider. About 60% of payments on SWIFT’s global payments innovation (gpi) tracker reach the recipient’s bank within 30 minutes, and nearly all arrive within 24 hours. The gap between “arrived at the bank” and “credited to the recipient’s account” is where delays creep in: local processing, time zone differences, and checks at the receiving end can add hours or days.
Several things slow a transfer further. If any bank in the chain flags the transaction during sanctions screening, a compliance officer must review it by hand. If the recipient’s name closely matches a name on an OFAC sanctions list, even as a false positive, the payment can be frozen while the bank investigates.3Office of Foreign Assets Control. OFAC Consolidated Frequently Asked Questions Transfers sent late Friday may not begin processing until Monday in the destination country. Public holidays anywhere along the chain add another day.
You can’t speed a compliance review along, but providing complete, accurate recipient information at the start reduces the odds of a false positive. For time-sensitive payments, send early in the week and early in the day.
What International Transfers Actually Cost
The cost hits you from several directions. The single fee your bank quotes is rarely the full number.
The Flat Fees
Your sending bank charges an outgoing wire fee, typically $25 to $50 for international transfers at major U.S. banks. If the payment routes through an intermediary, that bank may deduct its own fee before passing the funds along. The receiving bank may also charge an incoming wire fee. By the time the money arrives, the recipient can receive noticeably less than you sent.
Who Pays the Fees: OUR, SHA, and BEN
When you set up the transfer, your bank may ask you to choose a fee instruction, which is a code embedded in the SWIFT message:
- OUR means you pay all fees, including intermediary charges. The recipient gets the full amount. This is the most expensive option for the sender but ensures the recipient is not shortchanged.
- SHA, for shared, means you pay your bank’s outgoing fee, and the recipient absorbs intermediary and receiving bank fees, deducted from the transfer amount.
- BEN, for beneficiary, means the recipient pays everything, with all fees along the chain deducted from the transfer before it arrives.
SHA is the default for most consumer transfers. If you are paying an invoice or sending tuition where the recipient expects an exact amount, choose OUR so fees don’t eat into the payment and leave a balance due.
The Exchange-Rate Markup
The flat fee is usually the smaller expense. The bigger cost is baked into the exchange rate your bank offers. Banks don’t give you the mid-market rate you see on financial news sites. They add a markup, often called the spread, that typically runs 2% to 5% above the mid-market rate depending on the currency pair, the size of the transfer, and the institution. On a $10,000 transfer, a 3% spread costs $300, far more than a $45 wire fee.
Currency conversion can happen at your bank, at an intermediary, or at the receiving bank, and the rate depends on where it occurs. Sending money in the recipient’s local currency and converting before it leaves usually gives you more control because you can see the rate your bank applies. If you send U.S. dollars and let the recipient’s bank handle the conversion, you have no visibility into the markup until the money lands.
Federal law requires remittance transfer providers to show you the exchange rate, all fees, and the total amount the recipient will receive before you authorize the payment.4eCFR. 12 CFR 1005.31 – Disclosures If the provider cannot determine the exact rate at the time of transfer because conversion will happen at a foreign bank later, the disclosure must label the rate “Estimated” so you know the final payout could differ.5eCFR. 12 CFR Part 1005 Subpart B – Requirements for Remittance Transfers
If Something Goes Wrong
The 30-Minute Cancellation Window
Under Regulation E, you can cancel a remittance transfer up to 30 minutes after making payment, as long as the recipient has not already picked up or received the funds.6eCFR. 12 CFR 1005.34 – Procedures for Cancellation and Refund of Remittance Transfers Your request must give the provider enough information to identify you and the specific transfer. The window is tight. If you realize something is wrong, call the bank immediately.
Error Resolution After 30 Minutes
If you discover a problem after the cancellation window closes, you have up to 180 days from the disclosed availability date to file a notice of error with your provider.7eCFR. 12 CFR 1005.33 – Procedures for Resolving Errors Covered errors include situations where the wrong amount was sent, the money went to the wrong person, or the funds were never delivered. Once the provider receives your notice, it has 90 days to investigate and must report its findings within three business days of completing that investigation.
These protections apply specifically to remittance transfers as defined by Regulation E, which covers most consumer international money transfers. Large commercial or institutional payments may not carry the same rights, so businesses should verify error-resolution terms with their bank directly.
Fraud: Act Within Hours, Not Days
Wire transfers are a favorite target for fraud because they are fast, difficult to reverse, and cross jurisdictions where law enforcement coordination is complicated. The most common scheme is business email compromise, where a scammer impersonates a known contact, such as a vendor, a real estate attorney, or a company executive, and sends convincing instructions to wire money to a fraudulent account. The email often arrives at the worst possible moment: right before a closing, right before a payment deadline, timed so you feel pressure to skip verification.
The single best defense is voice verification through a known phone number. If you receive an email requesting a wire transfer or changing previously provided bank details, call the person at a number you already have on file, not a number from the suspicious email, and confirm the instructions out loud. This one step blocks the majority of these attacks.
If you do send money to a fraudulent account, time is everything. SWIFT’s fraud recovery guidelines note that stolen funds are typically moved out of the receiving account within 72 hours.8Swift. Market Practice Guidelines – Fraud Mitigation Part II – Recovery of Suspected Fraudulent Transactions When a bank sends a recall request with a fraud indicator, the receiving bank is expected to place a hold on the funds for three business days to allow police reports to be filed, followed by an additional 21 business days while legal claims are pursued. None of that helps if the money has already been withdrawn. Report fraud to your bank within hours.
Why Legitimate Transfers Get Held for Review
Every international wire passes through automated screening that checks names, countries, and transaction patterns against sanctions lists maintained by the U.S. Treasury’s Office of Foreign Assets Control.9FFIEC BSA/AML Manual. Office of Foreign Assets Control – Overview The screening also flags patterns suggestive of money laundering or terrorist financing under the Bank Secrecy Act.
The software casts a wide net. If the recipient’s name is similar to an alias on a sanctions list, even a common name that happens to be a partial match, the system generates a hit that requires a human compliance officer to review the transaction manually.3Office of Foreign Assets Control. OFAC Consolidated Frequently Asked Questions These false positives are the most common reason a legitimate transfer gets delayed a day or two.
Penalties for OFAC violations run up to $250,000 per violation or twice the transaction value, whichever is greater, which is why banks over-screen rather than risk missing something.9FFIEC BSA/AML Manual. Office of Foreign Assets Control – Overview
Reporting Requirements You Might Trigger
Sending money internationally does not, by itself, create a tax liability or a reporting obligation on your end. A common misconception is that wire transfers over $10,000 trigger an IRS filing requirement. Form 8300 applies to physical cash payments received in a trade or business; wire transfers are explicitly excluded from the definition of a “transaction in currency.”10Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 Your bank handles its own regulatory reporting behind the scenes. But if your international transfers are connected to foreign financial accounts, two separate rules may apply to you.
FBAR (FinCEN Form 114)
If you have a financial interest in or signature authority over foreign bank accounts whose combined value exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts with the Financial Crimes Enforcement Network.11Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) The $10,000 threshold is the aggregate value of all your foreign accounts combined, not any single account. The deadline is April 15, with an automatic extension to October 15. Penalties for non-willful failure to file can reach $16,536 per account per year in 2026, and willful violations carry penalties of $165,353 or 50% of the account balance, whichever is greater.
FATCA (IRS Form 8938)
The Foreign Account Tax Compliance Act imposes a separate reporting requirement through IRS Form 8938, filed with your annual tax return. The thresholds are higher than the FBAR and depend on filing status and whether you live in the United States or abroad:12Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers
- Living in the U.S., single or married filing separately: foreign financial assets exceed $50,000 on the last day of the tax year or $75,000 at any point during the year.
- Living in the U.S., married filing jointly: $100,000 on the last day or $150,000 at any point.
- Living abroad, single or married filing separately: $200,000 on the last day or $300,000 at any point.
- Living abroad, married filing jointly: $400,000 on the last day or $600,000 at any point.
FBAR and Form 8938 are not mutually exclusive. If you meet both thresholds, you file both. The forms cover overlapping but not identical sets of assets, and failing to file either one carries steep penalties. If you regularly send or receive international wires tied to accounts abroad, check whether your balances cross these lines.
