What is SWIFT / BIC Code?
A SWIFT code (also called BIC, Business Identifier Code) is the standardized 8 or 11-character identifier of a specific bank and branch in the global SWIFT network. It is required for international wire transfers to route funds to the correct institution.
Definition
SWIFT (Society for Worldwide Interbank Financial Telecommunication) is the messaging network that connects over 11,000 banks across 200+ countries. It does not move money itself — it sends payment instructions between banks. Each bank has a unique SWIFT/BIC code identifying its institution and (optionally) the specific branch. Format: 4-character bank code + 2-character country code + 2-character location code + optional 3-character branch code. Example: CHASUS33 = JPMorgan Chase (CHAS), USA (US), New York main office (33). For an international wire, the sending bank needs the recipient bank's SWIFT code plus the recipient's account number. The transfer can take 1–5 business days and typically costs the sender $15–50 in fees, plus 1–4% in currency-conversion margin.
Worked example
Sending USD from the US to a UK account at HSBC London: • Recipient bank: HSBC UK • SWIFT code: HBUKGB4B (HBUK = HSBC, GB = UK, 4B = London) • Account number: GB29NWBK60161331926819 (an IBAN) • Amount: $5,000 Fee structure: sending bank charges $35 wire fee + 2% currency margin (~$100), receiving bank may charge $10–25 fee, intermediary banks (if used) charge $10–25 each. Total cost: $145–185 on a $5,000 transfer. Wise, OFX, or CurrencyFair would deliver the same transfer for $25–60 total — typically 2–4% cheaper.
Why it matters
For most personal international transfers under $10,000, modern fintech alternatives (Wise, Revolut, OFX, Remitly) are cheaper and faster than SWIFT wires. SWIFT remains the standard for: business B2B payments, payments over $50,000, certain regulated transactions, and corridors where fintech alternatives don't operate. Knowing your bank's SWIFT code is still useful — it's often required for receiving wires even if you mostly use fintech for sending.

Frequently asked questions
How do I find my bank's SWIFT code?
Three sources: (1) your bank's website "International Wires" or "Receiving Wires" page; (2) the back of your debit card or your online banking dashboard; (3) call your bank directly — they'll provide it free. Don't use third-party "SWIFT code lookup" sites for actual transfers — verify with your bank first.
What's the difference between SWIFT and BIC?
They are the same thing. "BIC" (Business Identifier Code) is the official ISO 9362 name; "SWIFT code" is the colloquial term because the SWIFT network is what uses these codes. Banks use both terms interchangeably.
Is SWIFT going away?
Not soon. SWIFT processes ~$5 trillion in transfers daily and is the global default for B2B payments. Competing systems (China's CIPS, Russia's SPFS, blockchain-based Ripple/RippleNet) have made incremental inroads but none have replaced SWIFT for major international business payments. For consumer remittances, fintech alternatives have largely displaced SWIFT.

Mid-Market Rate
The mid-market rate is the midpoint between the buy (bid) and sell (ask) price of a currency in the global interbank market. It is the fairest reference rate available and what Google, Reuters, Bloomberg, and Wise all display as "the exchange rate."
Spread (Forex)
The spread is the difference between the buy (ask) price and the sell (bid) price of a currency. For retail customers, this gap is the primary way exchanges, banks, and brokers earn revenue — often disguised as a "commission-free" service.
