Nobody exits politely

A reserve currency is the money countries hold when they don't trust each other's paper: oil gets priced in it, debt gets issued in it, savings get parked in it, and trade gets settled in it. For almost 80 years that money has been the dollar.

Two weeks ago in Johannesburg, BRICS (Brazil, Russia, India, China, South Africa) invited 6 new members: Argentina, Egypt, Ethiopia, Iran, Saudi Arabia and the UAE. From January the group holds about 40% of the world's population, around 30% of its GDP, and 3 of the biggest oil exporters on the planet, added in a single afternoon.

You'd think that's front-page material. It mostly wasn't. The coverage I read treated it somewhere between a photo op and a curiosity, and the analysis pieces all converged on the same verdict: no common currency was launched, therefore nothing happened.

That gap (the weight of the thing versus the attention it got) is worth a post.

They're scoring the wrong event

The dismissals share one assumption: that the project is to launch a currency that replaces the dollar, and that failing to launch it means failing overall. Lula did float a common currency before the summit, the idea went nowhere, and the obituaries wrote themselves.

However, nobody inside the system is actually trying to replace the dollar tomorrow. What's being built is plumbing, and plumbing is boring on purpose. The logic goes as follows:

1. First, trade gets invoiced in local currencies. This year alone: China and Brazil agreed to settle trade in yuan, India paid for Emirati crude in rupees, Bangladesh paid Russia for a nuclear plant in yuan, and Russia now sells most of its oil in currencies that aren't dollars.
2. Then, settlement rails get built so those payments don't touch a New York bank on the way. China's system is small next to SWIFT, and it exists, which is the part that matters.
3. Last, and slowest, reserves follow. The dollar's share of global reserves was 71% in 1999. It's about 58% now.

No single item on that list is news. That's the point. A currency launch would be an event, and events can be stopped. Plumbing just accumulates.

The summit didn't fail to launch a currency. It added 6 more countries to the pipework, and 3 of them sell the oil.

What it looks like from the borrowing side

I should say where I'm looking from. I'm Brazilian. In 2002, when it looked like Lula would win the election, the real lost a third of its value and the IMF arrived with a $30 billion loan and a list of conditions attached in order to calm the markets down. Nothing about our factories or our farms had changed that year. What changed was confidence, priced in dollars, and the price of restoring it was letting someone else write our budget.

From the inside of the dollar system, the dollar looks like neutral infrastructure. From the borrowing side it's not neutral at all; it's a currency someone else prints, governing crises someone else triggers, resolved on terms someone else sets.

The honest objection to everything I've written is dependence: BRICS members still sell to Western consumers, bank through Western systems and buy Western technology, and you don't get to exit a system you depend on. It's a fair point and I'll concede most of it. But dependence explains why the exit is slow. It doesn't make the exit imaginary. You don't jump off the infrastructure you rely on: you build the alternative next to it, and you shift weight one contract at a time.

Which is a description of the plumbing.

The sharpest edge is Iran

Of the 6 invitations, Iran's is the one to watch. Since Washington left the nuclear deal in 2018, Iran has lived under maximum sanctions: locked out of dollar clearing, oil exports chased around the globe, its economy run as a proof that isolation works. Joining BRICS is Tehran's counter-bet: that the siege can be routed around, non-dollar lane by non-dollar lane, with the world's largest oil importers on the other side of the pipe.

Both bets can't pay out. Either the sanctions wall holds, or the plumbing routes around it and the wall becomes decoration. And a power that built its main weapon out of money tends not to shrug when the weapon stops firing. I find it fascinating how little of the summit coverage sat with that question, because it's the one with consequences measured in something other than basis points.

I won't predict how it resolves. I'll just note the direction of travel.

This turned into more of a geopolitics lecture than I planned!

Here's the part to keep. The dollar's privilege won't end with an announcement, and whoever waits for the announcement will report, correctly and uselessly, that nothing happened this week. Reserve currencies have changed hands before; the pound gave way within living memory, slowly, and then all at once at Suez. The incumbent didn't watch that politely, and there's no version of this where the current one does.

Nobody exits an empire politely. The empire answers, and the answer is never denominated in its own currency.
