FAQs

Can a wire transfer be reversed?

Domestic wires are effectively irrevocable once completed. The receiving bank can voluntarily return funds if notified quickly (before the recipient has withdrawn them), but there's no legal obligation to do so. International wires are even harder to reverse through the SWIFT network. If a wire is sent to a fraudulent account, recovery prospects are poor — prevention is essential.

What information is needed to send an international wire?

You need the beneficiary's full legal name, bank account number (or IBAN in Europe), bank name and address, SWIFT/BIC code, and correspondent bank details if required. For some countries, additional routing information (sort code in UK, routing transit number in US, BSB in Australia) is needed. Missing or incorrect information causes delays and returns.

When should I use a wire transfer versus ACH?

Use wires for: same-day settlement requirements, amounts exceeding ACH limits ($1M+), international transfers, or when irrevocability is required by the counterparty (e.g., real estate closings). Use ACH for: recurring payments (payroll, vendor payments), lower cost priority, US domestic transfers under $1M where same-day isn't critical.

A wire transfer is an electronic transfer of funds from one bank or financial institution to another, processed through dedicated messaging networks — Fedwire (operated by the Federal Reserve) for domestic US transfers, SWIFT (Society for Worldwide Interbank Financial Telecommunication) for international transfers, and CHIPS (Clearing House Interbank Payments System) for large-value domestic and international transactions.

Unlike ACH, wire transfers are processed individually in real-time (not in batch), are final and irrevocable (cannot be reversed once completed), and have no practical dollar maximum. These characteristics make wires the preferred mechanism for large transactions (real estate closings, M&A earnest money, large vendor payments), time-sensitive payments (same-day fund availability required), and international cross-border transfers.

Domestic wire costs typically range from $15–$50 per transfer at traditional banks, though many fintech platforms and neobanks have reduced or eliminated domestic wire fees. International wires are more expensive ($25–$65 per transfer) and involve additional SWIFT correspondent banking fees and exchange rate spreads that can add 1–4% to the total cost for currency conversion.

The SWIFT system is the messaging network that enables international bank-to-bank communication; the actual fund movement may pass through multiple correspondent banks before reaching the final beneficiary, which can add delays (typically 1–5 business days internationally) and fees at each correspondent. Newer payment rails like SWIFT GPI (Global Payments Innovation) have dramatically improved transparency and speed.

Wire transfers are the primary fraud target in business email compromise (BEC) scams — criminals impersonate executives or vendors and instruct employees to wire funds to fraudulent accounts. Because wires are irrevocable, BEC losses are typically unrecoverable. Robust verification procedures for wire instructions are critical.
