International Transfers: How Money Actually Moves Between Countries
Sending money across borders is one of those things that seems like it should be simple in 2026. You have an account here, someone has an account there, and money moves. In practice, international transfers involve multiple systems, hidden fees, unpredictable timing, and rules that vary by country. This guide explains what actually happens when money crosses borders, why costs and timing vary so much, and what tends to catch people off guard.

At a glance
Common transfer methods and what varies between them.
| Bank wire (SWIFT) | 1-5 business days Most universal; often highest fees; intermediary banks may charge extra |
| Transfer services | Minutes to 2 days Wise, Remitly, etc. Often cheaper; currency pairs and corridors matter |
| Multi-currency accounts | Instant (same platform) Hold multiple currencies; avoid conversion when possible |
| Exchange rate markup | 0.3% to 4%+ Often hidden; compare mid-market rate to offered rate |
| Common delays | Compliance holds Large amounts, new recipients, or certain corridors trigger review |
Key tradeoffs
Important considerations that affect most people in this situation.
Speed often comes with tradeoffs
Faster transfers sometimes cost more or have lower limits. Same-day transfers may require specific corridors or higher fees. What's fast for one currency pair may be slow for another.
Cheapest isn't always available
The lowest-cost option depends on the specific currency pair, amount, and destination. Services that work well for USD to EUR may not support other combinations. Checking multiple options before each transfer often saves money.
Convenience has a price
Your existing bank may offer the simplest path but rarely the best rates. Dedicated transfer services require setup but often provide better value. The effort of switching depends on how often you transfer.
Predictability varies by corridor
Some currency routes are fast and cheap. Others involve more intermediaries, higher fees, or less predictable timing. Popular corridors between major currencies tend to work better than less common combinations.
How international transfers actually work
Money doesn't physically move between countries. What moves is information and obligations between banks.
When you send an international transfer, your bank doesn't pack up cash and ship it overseas. Instead, banks maintain relationships and accounts with each other. Your bank reduces your balance and sends a message to the recipient's bank saying, effectively, 'pay this person.' The recipient's bank increases their customer's balance, trusting that the sending bank will settle the debt through their correspondent banking relationship.
This system works because banks maintain accounts with each other, often through intermediary banks that specialize in connecting financial systems. A transfer from a small credit union in the US to a regional bank in Portugal might pass through two or three intermediary banks before arriving. Each bank in the chain can charge fees and takes time to process.
The complexity varies by corridor. Transfers between major banks in common currency pairs (USD, EUR, GBP) tend to move through well-established channels. Less common combinations may require more intermediaries, take longer, or cost more. This is why the same transfer service can be fast and cheap for one route but slow and expensive for another.
Main ways to send money internationally
Different methods suit different situations. Understanding the options helps match the method to the need.
Bank wires (SWIFT transfers): The traditional method. You instruct your bank to send money to an account at another bank, identified by SWIFT/BIC code and account number or IBAN. Your bank handles the routing. This works for almost any bank-to-bank transfer but typically costs more ($15-50 in fees plus exchange markup) and takes 1-5 business days. Intermediary banks may deduct additional fees from the amount in transit.
Transfer services (Wise, Remitly, OFX, etc.): Specialized companies that handle international transfers, often at lower cost than banks. They work by maintaining their own accounts in multiple countries—your money goes to their local account, then they pay out from their account in the destination country. This can be faster and cheaper, but availability depends on the specific currency pair and corridor. Each service has different strengths.
Multi-currency accounts: Some services let you hold balances in multiple currencies. You convert when rates are favorable, then spend or transfer from that currency balance. This works well for people who regularly deal in multiple currencies but requires planning ahead. The conversion still has costs, but you control the timing.
Card-based methods and ATM withdrawals: Not exactly transfers, but relevant for accessing money abroad. Using a debit card abroad involves currency conversion at whatever rate your card issuer offers, plus potential fees. Some cards offer better rates than others. ATM withdrawals let you access cash but involve similar conversion costs plus ATM fees on both ends.
Where fees and exchange rate costs hide
The advertised fee is rarely the whole cost. Exchange rate markups often exceed visible fees.
Explicit fees: The fee you see when initiating a transfer. Banks often charge $25-50 for outgoing wires. Transfer services may charge less ($1-10) or calculate fees as a percentage. This is the visible cost, but usually not the largest one.
Exchange rate markup: The bigger cost for most transfers. When you send USD and the recipient gets EUR, someone converts the currency. The mid-market rate (what you see on Google or XE.com) is the baseline. The rate you're offered is marked up from that baseline. A 2% markup on a $5,000 transfer is $100—often more than the explicit fee. Some banks mark up 3-4% or more.
Intermediary bank fees: For SWIFT transfers, banks in the middle of the chain may deduct fees from the amount. You send $1,000, but $985 arrives because an intermediary bank took $15. This is often unpredictable and may not be disclosed upfront.
Receiving bank fees: The recipient's bank may charge for incoming international wires. This varies by bank and account type. The recipient might receive less than expected or face a separate fee.
Comparison approach: To understand true cost, compare what leaves your account to what arrives in the recipient's account. Calculate the effective exchange rate (amount sent divided by amount received) and compare to the mid-market rate. The difference is your total cost percentage.
Speed and predictability
Transfer timing depends on multiple factors, many outside your control.
Business days matter: Banks process transfers on business days in both the sending and receiving countries. A Friday transfer to a country with different weekends might not process until the following week. Holidays in any country along the chain can add delays.
Cut-off times: Banks have daily deadlines for processing transfers. Miss the cut-off and your transfer goes out the next business day. These times are often earlier than you'd expect, sometimes mid-afternoon.
Compliance review: Transfers that trigger fraud or money-laundering checks take longer. Large amounts, new recipients, certain countries, or unusual patterns can flag review. This adds hours to days of delay, often without clear communication about what's happening.
Typical timelines by method: Bank wires commonly take 1-5 business days. Transfer services range from near-instant to 2-3 days depending on the corridor and funding method. Same-day transfers are possible for some routes but may cost more or have limits. The specific corridor matters more than the general method.
What you can control: Initiate transfers early in the day, early in the week. Provide complete and accurate recipient information (errors cause delays). For large or time-sensitive transfers, verify the specific route's typical timing before committing.
Limits, checks, and why transfers get paused
Banks and transfer services have limits and compliance obligations that can affect your transfer.
Transfer limits: Most services have daily, weekly, or per-transfer limits. These may vary by verification level, account age, or transfer history. New accounts often have lower limits. Limits may differ by destination country. Exceeding limits requires splitting transfers or using a different method.
Compliance holds: Financial institutions must monitor for money laundering and fraud. Certain triggers cause transfers to be held for manual review. Common triggers include: large amounts (thresholds vary but $10,000+ often gets attention), transfers to certain countries, new recipients, unusual patterns compared to your history, and incomplete documentation.
Documentation requests: For large transfers or certain destinations, you may be asked to provide documentation about the source of funds or purpose of the transfer. This might include pay stubs, tax documents, sale contracts, or a simple written explanation. Being prepared to provide this speeds up processing.
Account restrictions: Problems with compliance checks can lead to account restrictions or closures. This is more common with transfer services than traditional banks, and more common when transfer patterns look unusual. Using services as intended and responding promptly to requests helps avoid problems.
Comparing your options
The best method depends on what you're optimizing for.
- For lowest cost on common corridors: Transfer services like Wise often beat bank wires significantly. Compare the mid-market rate to the offered rate to see the true cost difference.
- For reliability and universal access: Bank SWIFT transfers work for almost any bank account globally. Higher cost but fewer restrictions on destinations.
- For speed: Services offering instant or same-day transfers exist for popular corridors. May cost more or have lower limits. Verify the specific route's timing before counting on it.
- For large amounts: Banks may have higher limits than transfer services. Compliance review is likely regardless of method. Having documentation ready helps.
- For regular transfers: Setting up standing instructions or using services with repeat-transfer features saves time. Multi-currency accounts help if timing of conversion matters.
Common pitfalls
Issues that frequently catch people off guard in this area.
Common questions
How do I know if I'm getting a good exchange rate?
Compare the rate you're offered to the mid-market rate (shown on Google, XE.com, or similar). The difference is the markup. A 0.5% markup is competitive; 2-3% is common for banks; 4%+ is poor. Calculate: (mid-market rate minus offered rate) divided by mid-market rate.
Why did my transfer take longer than expected?
Common reasons include: weekends or holidays in sending or receiving countries, compliance review triggered by the amount or destination, missing or incorrect recipient details, intermediary bank processing times, or cut-off times being earlier than expected. Contact your service provider for specific status.
What's the difference between SWIFT and IBAN?
SWIFT (or BIC) is the bank identifier—it tells the network which bank to route the transfer to. IBAN is the account identifier—it tells that bank which account to credit. For transfers to most countries outside the US, you need both. US domestic transfers use routing numbers and account numbers instead of IBAN.
Can my transfer be reversed after I send it?
Generally, no. Once a transfer is processed, reversal requires the recipient's cooperation. If you sent to the wrong account, contact your provider immediately—there may be a brief window to cancel. For completed transfers, recovery depends on the recipient bank and account holder agreeing to return the funds.
Why do transfer services have different limits?
Limits reflect the service's regulatory status, risk tolerance, and verification of your identity. Higher verification levels usually unlock higher limits. Limits also vary by destination country based on compliance requirements. Check limits before committing to a service for large transfers.
