Why USD Dominates African Remittances While the GBP Corridor Stays Wide Open

According to World Bank estimates, people living abroad sent about $95 billion to Africa in 2024, helping millions of households pay school fees, cover medical bills, keep businesses running, and put food on the table.

Few people think about the journey that money takes after leaving London or New York. Behind nearly every transfer is a global payment system that was built around the US dollar long before today's digital economy.

That is why even transfers with no connection to the United States often pass through dollar infrastructure, not because the dollar is always cheaper or faster, but because no other currency is as widely used around the world.

How the Dollar Became the Default:

The dollar's dominance in global payments isn't random. It traces back to the aftermath of the Second World War, when the US emerged as the world's dominant economic power, and the dollar became the go-to reserve and trade currency.

Once that foundation was set, the system around it took shape through correspondent banking, where banks hold accounts with each other to settle cross-border payments. When two banks cannot settle directly, an intermediary bank steps in.

So, a transfer from London to Nigeria might pass through several correspondent banks before reaching its destination. Many of those hops settle through US dollar accounts, even when neither party is actually using dollars.

The more everyone used it, the stickier it got. Banks kept dollar liquidity on hand. Businesses priced trade in dollars. Payment providers followed the same rails because that's where the volume was. Today, the dollar accounts for about 45% of Africa's SWIFT payment traffic.

Why GBP Transfers Face a Different Problem:

The UK is one of Africa's largest remittance sources, sending more than $8 billion to the continent in 2023 alone. Migration and cross-border employment drive those flows.

Nigeria's UK diaspora is estimated at between 500,000 and 3 million people, depending on the source. Despite supporting one of Africa's busiest remittance corridors, many pound transfers still rely on infrastructure designed around the US dollar.

Instead of settling directly from pounds to naira or cedis, many payments convert pounds into dollars first, then into local currencies. Every additional conversion introduces another foreign exchange spread, reducing the amount received.

The numbers reflect that reality. World Bank data shows that UK-to-Ghana transfers carry a 3.24% exchange rate margin, compared with 1.80% for transfers from the United States. That gap reflects structural inefficiencies in the payment system rather than customer choice.

Why Hasn't the Market Fixed This:

The obvious fix sounds simple: just build direct pound to African currency markets. In practice, it's much harder than it sounds.

• Payment networks only work when enough buyers and sellers show up to create consistent liquidity.
• The dollar has that in spades because it dominates global trade, reserves, and commodities pricing.
• Sterling trades far less against African currencies, which makes direct pricing more expensive and less reliable.

Regulation piles on too. UK remittance providers must meet stringent safeguarding, sanctions, anti-money laundering, and consumer protection requirements. Those create high fixed costs before you process a single payment.

Where Fintech Is Making Progress:

Innovation hasn't stood still though. Rather than waiting for the whole system to change, payment companies are redesigning different parts of the cross-border chain.

TranzyPay is attacking this through direct payment infrastructure, transparent FX pricing, and local settlement networks. The goal is straightforward: cut out unnecessary middlemen and make cross-border transfers faster and more predictable.

Direct licensing reduces intermediaries. Stablecoins may improve settlement efficiency. Regional banking partnerships expand access to local payment networks. Each piece removes friction from a different part of the chain.

The Commercial Opportunity:

The opportunity is not to replace the dollar, but to reduce unnecessary dependence on it where direct settlement is practical and economically viable.

The dollar will remain central to global finance for years. The real winners will be providers that remove unnecessary complexity and make cross-border payments cheaper, faster, and more direct.
