The United States owns a weapon that has never fired a single shot. It has no explosives and no soldiers, and over the past twenty years it has changed more governments' behaviour than any aircraft carrier. It works like this: you are simply disconnected from money. Your bank cannot pay anyone, and nobody can pay you.

But this weapon has a strange property. It only works while it stays in the holster. Every time it is drawn, it gets a little weaker — and last Saturday, one more country quietly started building its way out.

On Saturday the nineteenth of July, in Beijing, the governor of the Central Bank of Libya, Naji Issa, met the governor of the People's Bank of China, Pan Gongsheng. They agreed to connect Libya's commercial banks to CIPS — the Cross-Border Interbank Payment System — to let Chinese banks guarantee Libyan trade deals, and to put some of Libya's savings into Chinese government debt.

Nothing has switched on yet: no Libyan bank appears on the CIPS participant list, and a banking forum is only planned for early next year. What was signed is an intention. But CIPS is real — it reaches banks in more than 180 countries, and in March it moved a record 1.22 trillion yuan in a single day. And Libya is not being punished, pressured, or fought. It simply decided that having one way to move money is a risk worth paying to fix.

Say a company in Libya pays a supplier in Vietnam. First the banks have to talk — this account, that account, this amount — and that messaging runs on SWIFT, a network connecting more than eleven thousand banks. Think of it as the postal service between banks: it carries the instructions, never the money.

Second, the money moves. Banks don't ship cash; they keep accounts with each other. And because nearly every bank needs to handle dollars, nearly every bank keeps a dollar account inside an American bank. So both banks' dollars sit in New York, and the payment is just a number moving between two accounts there — within reach of American law. When Washington sanctions a bank, it tells American banks: this account is closed. The messages still arrive. The money stops.

A chokepoint gives you power because everyone must pass through it. But a gun is just as dangerous after you fire it; this one is not. Every use forces the target to find another route — and once it does, that country is out of reach for good, and becomes a customer making a rival system more useful to everyone else.

In 2012, the US and Europe cut Iran's banks off the dollar. In 2022, Western governments froze around $300 billion of Russia's savings held abroad — and officials everywhere noticed at once that money kept abroad is only yours until someone decides otherwise. Russia moved into the yuan and joined CIPS. Then countries nobody had sanctioned started watching: central banks bought gold, which cannot be switched off, and Libya's central bank booked a flight to Beijing.

This is the point where a lot of videos would tell you the dollar is collapsing. It isn't. The dollar's share of the world's savings fell from about 72% in 2001 to roughly 57% today — but in the first quarter of this year it went up. The yuan is about 2% of reserves and 3% of payments; the dollar is one of the two currencies in nearly 90% of all currency trades.

And economists at the Centre for Economic Policy Research find no clear statistical link between sanctions and the dollar's decline, pointing to exchange-rate effects and ordinary diversification — and noting that sanctions are usually joint with Europe, Britain and Japan, so the euro, pound and yen are no refuge either. Notice what that argument is about: the dollar's share of savings. It is not about how many countries have built a second route — and that number only moves one way.

In 2012 the United States and Europe sanctioned Iran together, and Iran's banks were cut off with everyone's agreement — there was nowhere to run, because the exits were closed too. In 2018 the US walked out of the agreement limiting Iran's nuclear programme; Europe wanted to stay in, so Washington warned European companies they would lose their own access to American banking. That was when Europe — an ally — started designing a way around it.

The trade-off is time. Getting twenty-seven governments to agree is slow, and the sanction that emerges is weaker. It buys weaker punishment today in exchange for allies who stay inside the system tomorrow.

In 2019, France, Germany and Britain created INSTEX so European companies could keep trading with Iran without touching the American system. It processed essentially one transaction and was shut down in 2023.

The failure teaches more than a success would. The technology was never the hard part: payment systems run on habit and scale, and a new pipe is worthless unless enough banks already use it. On one side of the scale sat a small amount of Iranian trade; on the other, access to the dollar and therefore most of the world economy. The banks chose the dollar, and their governments could not make them choose otherwise. Building a way around the chokepoint is slow and expensive — but slow is not the same as never.

The third design gives up the chokepoint entirely: instead of one dominant rail with alternatives slowly growing around it, you build several from the start. A working prototype already exists — mBridge, built by the central banks' own bank in Switzerland with the central banks of China, Thailand, the UAE and Hong Kong, alongside dozens of national digital currencies.

In that world, no one can be switched off. That sounds like good news, and it is exactly the problem. Financial sanctions are the main tool the world has for punishing a government without shooting at it; cutting a country off has stopped wars from being financed and forced governments to the table. Remove the chokepoint and you remove that too — not only from Washington, but from any future coalition that would rather sanction an aggressor than fight one.

The strange thing about a chokepoint is that its power is measured by how much of the world has no alternative — and using it is precisely what gives people a reason to find one. Using it costs something every time, but that cost never shows up on anyone's desk. Each decision to draw the weapon can be completely reasonable on its own, and the bill still arrives.

Libya's agreement changes almost nothing on its own. Nothing has switched on, and the yuan remains a rounding error next to the dollar. But it is one more line on a map, drawn by a country nobody was punishing — which is exactly the kind of line that tells you where a system is heading. The question worth watching is not whether the dollar falls. It is how often the weapon gets drawn.
