What's documented

Project mBridge is a payment platform that lets central banks settle cross-border transactions directly in their own digital currencies — no dollar, and no SWIFT messaging, required in the middle. It's built and run by the central banks of China, Hong Kong, Thailand, and the United Arab Emirates, joined by Saudi Arabia in 2024. As of mid-2026, the platform had processed roughly $69 billion (470 billion yuan) in cumulative transactions — up from $55 billion just seven months earlier, and from just $22 million in 2022 — real, if still modest, growth in traffic that used to have no reason to avoid the dollar-based system at all.

The project started under the Bank for International Settlements, the "central bank for central banks" based in Switzerland, which built the technology alongside the four founding members. On October 31, 2024, the BIS stepped back from the project entirely, handing full control to the participating central banks. BIS General Manager Agustín Carstens said the BIS had "graduated out" — the project had matured enough that the BIS's involvement was no longer needed, he said, and he's stated the decision wasn't politically driven: "not because it was a failure and not because of political considerations but instead because we have been involved for four years."

Why the timing is the actual story

About a week before the BIS exit, Russian President Vladimir Putin, at the October 2024 BRICS summit in Kazan, proposed a "BRICS Bridge" payment system — which Bloomberg and other outlets reported was built on technology comparable to mBridge's — as a way for countries to route around Western sanctions and reduce dependence on the dollar. The BIS's exit came shortly after. The BIS's own explanation — project maturity, nothing more — is on the record and hasn't been retracted. But the sequence is exactly the kind of thing that invites a "why now" question, and Western reporting on the withdrawal consistently notes the same timing without being able to prove Putin's comments caused it.

Here's what's actually true and provable: mBridge involves China and the UAE, both members of the expanded BRICS bloc that includes Russia. Nothing prevents the underlying technology or expertise from informing a separate system Russia or Iran could build on their own — a "clone," not literal access to mBridge itself, since Russia and Iran aren't members. The BIS itself has stated mBridge cannot be used to bypass sanctions as currently built. Whether that holds if the technology gets replicated elsewhere is a different, open question nobody has answered with evidence yet.

Who's watching, and why that matters

The list of mBridge's "observing members" — central banks monitoring the project without building on it — includes more than 30 institutions across Asia, Africa, Europe, and the Americas. Two names on that list are notable: the Federal Reserve Bank of New York (through its Innovation Centre) and the European Central Bank. Institutions tied to the two currencies with the most to lose from a dollar/euro-bypass system are both watching a project explicitly designed to reduce dependence on both.

Saudi Arabia is the detail that actually moves the needle

China, Hong Kong, Thailand, and the UAE joining a dollar-alternative payment system is notable. Saudi Arabia joining is different in kind. Since a 1974 US-Saudi financial and security arrangement, Saudi oil sales have been priced and settled overwhelmingly in dollars — the informal "petrodollar" convention that's one of the load-bearing pillars of dollar demand worldwide. A founding member of the platform designed to settle payments without the dollar being the kingdom that sells the commodity the entire dollar-reserve system was built around is the single fact in this story with the most actual weight behind it.

What this piece is not saying

This isn't a claim that mBridge is secretly a sanctions-evasion tool, or that the dollar's global role is collapsing. The BIS's statement that the platform can't be used to bypass sanctions as designed is a real, on-the-record claim, not spin — and $69 billion in cumulative transactions since 2022 is real activity, but it's a rounding error against the trillions that move through dollar-based systems every single day. This is a documented, early-stage shift in infrastructure with genuinely significant members (especially Saudi Arabia), not a completed one.

It's also not saying Putin's comments proved the BIS's exit was political — that's a connection the timing invites, not one anyone has proven. The BIS's own explanation stands unless and until something contradicts it.
