If you’ve ever sent money abroad and watched it crawl through your bank over several days, picking up mysterious fees along the way, you’ve met SWIFT, even if nobody told you its name. SWIFT sits at the heart of how international payments have worked for the last fifty years. And here’s the twist most people don’t realise: SWIFT doesn’t actually move your money at all.
Let’s clear that up.
What is SWIFT, in plain English?
SWIFT stands for the Society for Worldwide Interbank Financial Telecommunication. It was founded in 1973 to replace Telex, the slow, clunky messaging system banks used before it.
At its core, SWIFT is a secure messaging network. It connects more than 11,000 financial institutions across over 200 countries, and it lets them send each other standardised, secure instructions about money. Think of it as the world’s most trusted group chat for banks.
So SWIFT doesn’t actually move money?
Correct, and this is the single most important thing to understand. SWIFT carries instructions, not cash.
When your bank in Lagos sends money to a bank in London, SWIFT delivers a message that says, in effect, “please pay this amount to this account.” The actual money moves through a chain of banks that hold accounts with each other, a system called correspondent banking.
Picture it like sending a parcel through a series of post offices that each know and trust the next one. SWIFT is the tracking and instruction system. The banks in between are the ones physically passing the parcel along.
Why are SWIFT transfers so slow and expensive?
Because of that chain. If your bank doesn’t have a direct relationship with the recipient’s bank, the payment has to hop through one or more intermediary banks. Each hop adds time, and each bank in the chain can take a cut.
That’s why a single international transfer can take days and lose a frustrating slice to fees you never fully see itemised. The more obscure the route between two countries, the longer and pricier it tends to be, which hits exactly the regions that can least afford it.
What is a SWIFT or BIC code?
When you send money internationally, you’re often asked for a SWIFT code, also called a BIC (Bank Identifier Code). It’s simply the unique address that identifies a specific bank on the SWIFT network, so the instruction reaches the right institution. It’s the equivalent of putting the correct address on that parcel.
What is SWIFT gpi and ISO 20022?
SWIFT knows it has a speed and transparency problem, so it has been modernising.
SWIFT gpi (Global Payments Innovation) added end-to-end tracking, faster processing, and clearer fee information, so banks and customers can finally see where a payment is, a bit like tracking a delivery.
ISO 20022 is a newer, richer messaging standard that the industry has been migrating to, with the old and new systems’ coexistence period ending in late 2025. In plain terms, it lets payment messages carry far more structured detail, which improves automation, compliance checks, and accuracy. Less manual fixing, fewer errors, smoother payments.
What are the alternatives to SWIFT?
This is the exciting part for fintech. The slowness and cost of correspondent banking is precisely the gap that newer players are attacking. Real-time payment rails, money-transfer fintechs, and stablecoins all promise to move value across borders faster and cheaper than the traditional chain of banks.
For African markets, where cross-border payments are notoriously painful and expensive, this matters enormously. The question over the coming years is whether SWIFT can modernise fast enough, or whether something built for the internet age routes around it.
Frequently asked questions
Does SWIFT hold or transfer my money? No. SWIFT only sends payment instructions between banks. The money itself moves through correspondent banking relationships.
What is a SWIFT code? A unique code (also called a BIC) that identifies a specific bank on the SWIFT network.
Why do SWIFT transfers take so long? Because payments often pass through several intermediary banks, each adding time and potential fees.
What’s replacing SWIFT? Nothing has replaced it yet, but real-time payment systems and stablecoins are increasingly competing for cross-border payments.
