Five central banks are commercializing mBridge, a blockchain payment network that has already settled nearly $69 billion, just as Washington races to put the dollar on its own rails.
The mBridge platform is preparing for commercial rollout. The Financial Times reported earlier this month that China, Hong Kong, Saudi Arabia, Thailand, and the United Arab Emirates are launching a cross-border digital currency payment network, with a Hong Kong-based entity tapped to promote it commercially. The system has already processed roughly 470 billion yuan in transactions. That’s nearly $69 billion in real settlement volume, not testnet theater.
The platform runs on blockchain rails and is built around central bank digital currencies. It is designed to be faster than SWIFT, cheaper than correspondent banking, and to reduce reliance on the dollar. According to the sources cited by the FT, the network is now under Chinese leadership and will be promoted as a cheaper, easier alternative to the legacy messaging system that has anchored international payments since 1973.
This is not a whitepaper. It’s not a proof of concept. This is operational infrastructure.
The context: SWIFT’s monopoly was always vulnerable, but no one had the scale to challenge it until now.
For more than fifty years, cross-border payments have run through the Society for Worldwide Interbank Financial Telecommunication. SWIFT doesn’t move money. It moves messages between banks, which then settle through correspondent accounts. The system is slow, expensive, and opaque. A wire transfer from Bangkok to Dubai can take days and cost real money in fees because it hops through New York, London, and Frankfurt along the way.
Every hop is a point of control. The U.S. Treasury can freeze Iranian oil revenue. The EU can sanction Russian gas payments. SWIFT isn’t neutral infrastructure. It’s geopolitical leverage dressed up as a utility.
mBridge didn’t start as a Chinese project. It was incubated inside the Bank for International Settlements Innovation Hub, with the original pilot including the central banks of China, Hong Kong, Thailand, and the UAE. Saudi Arabia joined later. Then, in late 2024, the BIS stepped back from direct involvement amid geopolitical concerns. That detail matters: the story here isn’t “the BIS built a payment system.” It’s that China and its partners are taking a BIS-incubated project and commercializing it independently. The system uses distributed ledger technology to connect central bank digital currencies directly. No correspondent banks. No SWIFT codes. No dollar on-ramps.
According to reporting from multiple outlets this week, the platform has already moved hundreds of billions of yuan in real transactions. That volume didn’t happen by accident. It happened because the participants needed an alternative, and mBridge gave them one that works.
What this actually means: The dollar’s payment monopoly is under siege, and the weapon is a blockchain.
I traded emerging markets FX through the Asian devaluation crisis in 1997. I saw what happens when currencies lose access to dollar liquidity. Countries capitulate. They restructure. They take IMF loans with conditionality that rewrites their fiscal policy. The ability to freeze someone out of the payment system is the most powerful sanctions tool the U.S. has ever had.
mBridge weakens that leverage. It doesn’t erase it.
If Saudi Arabia can settle oil invoices in digital yuan through a blockchain network that never touches New York, the Treasury’s sanctions desk loses some of its grip. If Thailand can pay for Chinese electronics without converting baht to dollars and back, the correspondent banking system becomes optional for that flow. If the UAE can intermediate Gulf trade flows on a permissioned ledger that clears in hours instead of days, SWIFT becomes one option rather than the only one. The Treasury doesn’t lose its veto overnight, though. Secondary sanctions still bite, trade finance still runs on dollars, and access to U.S. capital markets and dollar liquidity still matters. What changes is that, for the first time in fifty years, participating countries have another door.
The timing is not coincidental. The GENIUS Act is now the framework U.S. issuers are racing to satisfy. State Street launched a dedicated stablecoin reserves money market fund earlier this month, Fidelity rolled out its own stablecoin reserves fund this week, and they join BlackRock and Goldman, who got there first. Treasury bills are being tokenized at scale. Wall Street is building the infrastructure to put dollars on blockchain rails.
But China got there first with a central-bank-sponsored cross-border CBDC network, and they brought the oil money with them. Stablecoins already settle hundreds of billions a month, and USDT and USDC are already global. What China reached first isn’t onchain dollars; it’s a sovereign, state-backed settlement rail built to route around them.
The participants in mBridge represent a significant share of global energy exports, Asian manufacturing capacity, and Gulf capital flows. According to the FT report, a Hong Kong-based entity will promote the network commercially. That means onboarding corporates, not just central banks. That means trade finance. That means letters of credit, escrow, and supply chain settlement potentially moving off SWIFT and onto a Chinese-led blockchain.
The broader implication: if mBridge scales, it fractures the international payments system into two networks. One runs through New York and uses dollars. The other runs through Hong Kong and Shanghai and uses CBDCs. The countries that matter most to global trade, energy, and manufacturing will have a choice. And the choice won’t always be the dollar.
The real fight isn’t mBridge versus SWIFT. It’s CBDC rails versus stablecoin rails.
Here’s the part most coverage misses. The easy story is “China is attacking SWIFT.” SWIFT is a fifty-year-old messaging layer, and yes, it’s vulnerable. But the deeper, more important contest is over what replaces it. China’s answer is a state-run CBDC network. America’s answer is private-sector stablecoins. That’s the strategic map worth holding in your head:
ModelChampionCBDC networkChina / mBridgeStablecoin networkU.S. private sectorMessaging networkSWIFT (legacy)Tokenized depositsGlobal banks
These are fundamentally different bets. mBridge is a closed, permissioned, state-controlled system: central banks issue the money, central banks run the ledger, and the whole point is sovereign control over settlement. The U.S. approach inverts that. Under the GENIUS Act framework, the dollar moves onchain through regulated private issuers, not a Federal Reserve CBDC. America is betting that open stablecoin rails, with Wall Street reserves behind them, out-compete a government network on reach, liquidity, and developer adoption.
So when you read that mBridge settled $69 billion, the right question isn’t “will it kill SWIFT.” It’s “which design wins the next decade of cross-border money.” China is building CBDC rails while the U.S. is building stablecoin rails, and both are racing to define the standard before the other locks it in. That’s the competition investors should actually be tracking.
What it means for you: The stablecoin boom in the U.S. is a direct response to this threat.
The GENIUS Act wasn’t passed because Congress suddenly loves crypto. It was passed because lawmakers understood that if the dollar doesn’t move onto blockchain rails, someone else’s currency will. Tokenized Treasury bills, stablecoin reserve funds, and regulated digital dollar issuance are defensive moves. They are attempts to preserve the dollar’s role in a world where payments are moving onchain whether Washington likes it or not.
The mBridge rollout makes that urgency real. If cross-border payments start routing around SWIFT, the U.S. loses visibility into trade flows and sanctions enforcement becomes harder. Over time, widespread non-dollar settlement could also erode one of the structural drivers of Treasury demand. Foreign central banks hold Treasuries in part because they need dollars to settle trade. The steps from CBDC settlement to reduced dollar usage to lower Treasury demand are linked, not identical, but the direction is clear: if countries need fewer dollars to settle trade, the marginal case for holding as many Treasuries weakens.
The infrastructure challenge is no longer theoretical. The nearly $69 billion in settlement volume that already ran through mBridge proves the rails work. The strategic question is whether adoption stays regional or goes global, and whether the dollar can move onto blockchain rails fast enough to compete.
For individual investors, this is not a buy signal or a sell signal. It’s a structural shift. The assets that benefit are the ones that operate in a multi-currency, blockchain-native payment world. Stablecoins that settle across chains. Protocols that enable cross-border liquidity without intermediaries. Infrastructure that reduces the cost and friction of moving value internationally.
The assets that suffer are the ones that depend on dollar monopoly and legacy settlement. Correspondent banks. SWIFT messaging revenue. Payment processors that charge rent on currency conversion.
The old model assumed that if you wanted to do international business, you had to touch dollars. That assumption is breaking.
What to watch next: Does mBridge onboard a major European or Latin American participant?
The current coalition is China, Hong Kong, Saudi Arabia, Thailand, and the UAE. That’s enough scale to matter, but it’s not enough to replace SWIFT. The next signal will be whether a G7-adjacent country or a major Latin American economy joins the network.
If Brazil, Turkey, or Indonesia sign on, mBridge becomes a credible payment rail for much of the Global South. If Germany or France engage, even as observers, the narrative shifts from “China’s payment network” to “the multilateral SWIFT alternative.”
The U.S. response will tell you everything. If Treasury starts pressuring allies not to join, mBridge is a real threat. If they ignore it, it’s still contained. And if the Fed suddenly accelerates work on a wholesale CBDC or pushes harder on stablecoin interoperability, you’ll know they’re playing catch-up.
The nearly $69 billion in volume is the proof of concept. The commercial rollout is the launch. The next six months will show whether this is a regional payment network or the beginning of a parallel financial system that doesn’t run through New York.
SWIFT’s monopoly has lasted more than fifty years. It won’t last forever. And right now, the alternative is live, operational, and backed by the central banks of countries that together account for a major share of global energy exports and manufacturing capacity. That’s not a headline. It’s the opening move in a new payments era.

From my limited knowledge, I think it is possible that G7 or other OECD countries may get involved with project mBridge. But wouldn't it be more likely that they play it safe with other projects such as Dunbar, Icebreaker and Agora?; at least for the time being.
As of right now, it seems like joining mBridge will cause political contention on the world stage
