mBridge’s $55.49 billion total brought wholesale CBDC scale into focus

By January 17, 2026, a new set of institutional data had put Project mBridge at a scale that was difficult to dismiss as a laboratory exercise. The Atlantic Council’s Dollar Dominance Monitor recorded $55.49 billion in cumulative cross-border settlement value through November 2025, up from $22 million in the project’s 2022 pilot. Reuters reported on January 16 that the platform had processed more than 4,000 transactions; crypto-industry coverage carried the milestone into January 17.

The central fact was scale, not a launch. Dividing $55.49 billion by $22 million yields roughly 2,522, so the widely used description of about 2,500-fold growth was a reasonable rounded comparison. It did not mean activity grew 2,500%—a materially smaller claim—and it did not describe a one-day or one-month flow.

What mBridge actually was

mBridge was a wholesale multi-central-bank digital currency network, not a retail cryptocurrency or a dollar stablecoin. The Bank for International Settlements said the project began in 2021 with the central banks or monetary authorities of China, Hong Kong, Thailand and the United Arab Emirates. Saudi Arabia joined in 2024. The network used a purpose-built distributed ledger to support peer-to-peer cross-border payments and foreign-exchange settlement in central-bank money.

The platform reached minimum viable product status in mid-2024. The BIS then began transferring the project to its central-bank partners and said in October 2024 that it was handing the work over. That chronology mattered on January 17, 2026: the reported volume represented activity on a partner-run prototype or minimum viable platform, not a new BIS-operated global payment system.

Official records also showed movement beyond simulated testing. The UAE Ministry of Finance said on November 11, 2025 that the federal ministry and Dubai Finance completed the country’s first government financial transaction using the Digital Dirham. The pilot used mBridge, integrated with the UAE central bank’s systems, and completed in less than two minutes. That record established a concrete government use case, although it did not by itself verify the platform-wide $55.49 billion total.

The yuan concentration

The Atlantic Council and Reuters estimated that China’s e-CNY accounted for about 95% of mBridge settlement volume. Applied mechanically to $55.49 billion, that share would equal approximately $52.7 billion. This is a Coinburn calculation, not a separately reported platform total, and “about 95%” makes the result inherently approximate.

That concentration cut two ways. It showed that sovereign digital-currency settlement had achieved meaningful transaction value on shared infrastructure. It also showed that the headline aggregate was not evidence of balanced adoption across all five participating currencies. A multi-country design could still be dominated by one currency’s transactions.

What the milestone did not prove

Cumulative settlement value is gross throughput over time. It is not money held on the network, market capitalization, unique users, average daily volume or a measure of transactions that would otherwise have used dollars. The public institutional record available by January 17 did not provide a transaction-level dataset sufficient to independently reproduce the $55.49 billion figure or the estimated currency mix.

The milestone therefore mattered as evidence that wholesale CBDC infrastructure had moved beyond a small 2022 pilot. It did not establish that mBridge was production-ready everywhere, that it had displaced correspondent banking, or that it threatened the dollar’s reserve role. On the evidence available on January 17, the defensible conclusion was narrower: central-bank digital settlement had reached substantial cumulative value, but its use remained highly concentrated and its operating data remained only partly transparent.
