Key tradeoffs
Important considerations that affect most people in this situation.
Bank Wire Transfers
- • Direct bank-to-bank path
- • Often required for large amounts
- • May involve intermediary banks
- • Fees can be unpredictable
Transfer Services
- • Often simpler interface
- • Typically show fees upfront
- • May have transfer limits
- • Regulatory status varies by country
Where transfers break down
Transfers move through multiple checkpoints. Each is a potential failure point. The sending bank verifies your request. Intermediary banks relay the funds. The receiving bank credits the account.
Problems can occur at any step. Some cause immediate rejection. Others create delays of days or weeks. The worst cases involve money sitting in limbo while banks investigate.
Most failures happen early in the process—incorrect details, compliance flags, or account restrictions. These are easier to fix. Mid-transfer problems are harder to resolve.
Account detail errors cause most failures
Small mistakes in account information create big problems.
Banks don't always verify details before attempting the transfer. The error surfaces when the destination bank can't match the details. The money then returns—slowly—minus fees.
- Transposed digits in account numbers
- Missing or incorrect SWIFT/BIC codes
- Name mismatches between sender's records and actual account name
- Wrong account type selected (checking vs. savings)
- Missing reference codes required by the recipient
Intermediary banks add unpredictability
Most international transfers don't go directly from your bank to the recipient's bank. They pass through one or more intermediary banks that handle routing between currency zones.
Each intermediary may take a fee. Your bank might not know the exact amount in advance. A transfer quoted at $30 could arrive with $50-80 deducted if multiple intermediaries are involved.
Intermediaries also add time. Each handoff is a potential delay. Compliance checks at any point can pause the transfer without notice.
Compliance holds happen without warning
Banks must screen transfers against sanctions lists and suspicious activity patterns. This is automatic. Most transfers pass instantly. Some don't.
Holds can be triggered by amount, destination country, sender or recipient names matching databases, or patterns that don't fit your account history.
When a hold occurs, you may not be notified immediately. The transfer simply doesn't arrive on schedule. Getting status updates requires active inquiry.
Currency conversion timing affects what arrives
Exchange rates change constantly. The rate shown when you initiate a transfer may not be the rate applied when conversion actually happens.
Some services lock the rate at initiation. Others convert at some point during processing. The difference can be significant for larger amounts or volatile currency pairs.
Receiving in a different currency than the account holds creates another conversion. If you send EUR to a USD account, the recipient's bank may convert at their rate, not yours.
Weekends and holidays extend timelines
Banking is not 24/7. Transfers initiated Friday afternoon may not begin processing until Monday. Bank holidays in any country along the transfer route add delays.
This matters for time-sensitive payments. Rent due Monday requires a transfer initiated earlier in the week, not Friday.
Holiday calendars differ by country. A normal business day where you are may be a bank holiday in the destination country or an intermediary country.
Fee structures vary more than expected
Transfer costs include more than the headline fee.
Some services advertise 'no fees' while building cost into the exchange rate. Comparing actual delivered amounts matters more than comparing stated fees.
- Sending bank's outgoing transfer fee
- Exchange rate markup (sometimes significant)
- Intermediary bank fees (often unpredictable)
- Receiving bank's incoming transfer fee
- Currency conversion fees if receiving in different currency
When transfers return to sender
Failed transfers eventually return, but not quickly. The money reverses through the same chain it attempted going forward. This can take days to weeks.
Returned transfers often come back minus fees. Intermediary banks may still charge for their handling even though the transfer failed. The sending bank may charge for processing the return.
Getting a clear explanation of why a transfer failed is difficult. Banks cite 'compliance reasons' or 'account restrictions' without detail. You may need to gather information from both ends.
