WHY THE DOLLAR STILL WINS — AND WHERE IT’S STARTING TO LOSE

This isn’t an accident, and it isn’t really about preference. It’s structural. Understanding why reveals a lot about how global payments actually work — and why that structure is now, slowly, starting to change.

The Logic of a Shared Language

Currencies behave a lot like languages. English isn’t spoken globally because it’s inherently superior to other languages — it’s spoken globally because enough people already speak it that learning it gives you access to everyone else who does. 

The dollar occupies the same position in trade finance. A business doesn’t need dollars because it loves the United States. It needs dollars because:

• Global trade is still overwhelmingly invoiced in USD.
• Correspondent banking is built around the dollar,because it is the deepest and most liquid market on the planet.
• Switching to a different settlement currency requires both sides of a transaction to agree to it. One willing party isn’t enough — you need a counterparty, and a bank on the other end capable of handling that currency.

The result is a kind of institutional inertia. Even when neither trading partner is American, the dollar often becomes the default meeting point simply because it’s the one currency almost everyone’s banking infrastructure is already built to handle. 

Economists call this a network effect, and it’s remarkably durable — not because it’s optimal for any individual transaction, but because it’s optimal for a system that has to work for millions of transactions at once.

Where the Cracks Are Starting to Show

None of this means the dollar’s role is fixed forever. What’s changing is quieter: regional settlement systems letting neighboring economies transact directly, without a third currency in between.

A clear example comes from Southern Africa. The region’s cross-border real-time settlement system, SADC-RTGS, has processed transactions exclusively in South African rand since it was established in 2013 — over a decade of every single regional payment passing through one currency, largely because South Africa’s banking infrastructure was the most developed in the bloc. 

This month, a second currency was added: the Angolan kwanza — cutting out the US dollar conversion that regional trade previously relied on as an unnecessary middle step.

It’s a small change, but part of a broader pattern: businesses and central banks questioning why a payment needs a third currency’s detour at all — and building infrastructure to remove it.

Convenience, Not Conviction

It’s worth being precise about what this shift actually represents, because “de-dollarization” gets used loosely to describe everything from geopolitical strategy to genuine market efficiency. 

What’s happening in cases like SADC-RTGS is not a political statement about the dollar — it’s a cost and speed calculation. Converting Angolan kwanza to US dollars and then to South African rand means two conversions, two spreads, and additional settlement time, for a transaction between two countries that share a regional trade relationship and, increasingly, the payment infrastructure to settle directly.

The dollar isn’t losing its position because it’s fallen out of favor. It’s facing competition, in specific corridors, from settlement paths that are simply more direct for the businesses actually using them. 

Why This Matters for How Payments Get Built

The real story isn’t about the dollar — it’s about payment infrastructure catching up to how trade actually works. For decades, transactions defaulted to whichever currency was most liquid, regardless of its connection to either party.

As regional systems and multicurrency platforms make direct settlement genuinely practical, that default starts looking less like a law of nature and more like a historical workaround.

This is the space MAGMA works in: building infrastructure that lets money move directly between the currencies that matter, rather than defaulting to whatever’s easiest for the banking system underneath. 

The dollar isn’t going anywhere soon — but corridor by corridor, the assumption that every payment must pass through it is becoming less true.
