In a landmark development for global finance, China's mBridge cross-border central bank digital currency (CBDC) platform has processed over $55 billion in cumulative settlements, with its Phase 4 pilot reducing transaction costs by up to 98% and settlement times from days to seconds. As the Bank for International Settlements (BIS) pivots to the Western-led Project Agorá, the global payments infrastructure is fracturing into two competing digital currency corridors — one China-aligned, one Western. This structural fragmentation of cross-border payments is one of the most consequential yet underreported shifts in global finance this year.
What is mBridge and Why Does It Matter?
mBridge (Multiple CBDC Bridge) is a blockchain-based platform enabling real-time, peer-to-peer cross-border payments and foreign exchange transactions using central bank digital currencies. Developed jointly by the Hong Kong Monetary Authority, the Bank of Thailand, the Central Bank of the UAE, the People's Bank of China's Digital Currency Research Institute, and the BIS Innovation Hub Hong Kong Centre, the platform reached minimum viable product (MVP) stage in mid-2024. Saudi Arabia's central bank joined in June 2024, and South Korea participated in the latest pilot. The platform uses Hyperledger Besu blockchain technology with automated forex conversion, allowing participating central banks to settle transactions directly without intermediaries.
The rise of CBDC platforms like mBridge represents a direct challenge to the dollar-centric correspondent banking system that has dominated global trade for decades.
Phase 4 Pilot Results: A Quantum Leap in Efficiency
In March 2026, mBridge completed its Phase 4 pilot, processing $4.3 billion in test settlements over 90 days ending in February 2026. The results were staggering:
- Settlement time: Reduced from 3-5 days to under 10 seconds
- Transaction costs: Cut by approximately 98%, from 1.5-3.5% to just 0.02-0.05%
- Compliance review time: Slashed from 24 hours to under 3 minutes
- Daily throughput: Up to 1,240 transactions with 94% settling within target windows
The pilot involved six central banks — China, Thailand, UAE, Saudi Arabia, Hong Kong, and South Korea — and demonstrated the platform's readiness for real-world trade settlement. The BIS announced that mBridge will transition to a full MVP phase in Q3 2026, with Indonesia, Turkey, and Brazil expressing interest in joining. These efficiency gains are particularly significant for energy and commodity trade settlement, where traditional correspondent banking can take days and cost up to 3.5% of transaction value.
The BIS Pivot: From mBridge to Project Agorá
The BIS's decision to exit mBridge in October 2024 marked a turning point. Citing concerns that the platform's technology could be used to circumvent sanctions and threaten the dollar, BIS CEO Agustín Carstens stated that mBridge was not created to serve BRICS or violate sanctions. However, the participating central banks continued developing the platform independently, with China's digital yuan (e-CNY) now accounting for over 95% of settlement volume.
In parallel, the BIS launched Project Agorá, a Western-anchored initiative exploring tokenized wholesale cross-border payments through a multi-currency unified ledger. Agorá brings together seven central banks — including the Federal Reserve Bank of New York and central banks from Europe, Japan, South Korea, and Mexico — along with over 40 financial institutions. The project entered real-world testing in 2025 and is expected to produce a lessons-learned report by mid-2026. Unlike mBridge, which uses a single shared ledger, Agorá aims to create an interoperable "network of networks" that integrates tokenized commercial bank deposits with wholesale CBDCs.
The fragmentation of global payment infrastructure into competing blocs raises profound questions about the future of international financial governance.
De-Dollarization in Practice: Energy and Commodity Trade
mBridge is increasingly used for trade settlement in energy and commodities, traditionally the bedrock of dollar hegemony. The platform enables direct yuan-dirham, yuan-baht, and yuan-riyal settlements without dollar intermediation. Iran has begun charging yuan tolls at the Strait of Hormuz, and BRICS nations are accelerating de-dollarization through the proposed "BRICS Bridge" — a unified cross-border payment architecture based on mBridge technology.
According to the Atlantic Council's Alisha Chhangani, rather than displacing the dollar outright, China is building parallel settlement rails that may incrementally erode dollar dominance in specific corridors and use cases. The e-CNY now accounts for 95.3% of mBridge settlements, highlighting China's dominant role. PBOC Governor Pan Gongsheng has placed the digital yuan within China's vision for a multipolar international monetary system, positioning it as a strategic counterweight to dollar hegemony.
Chinese regulators have directed banks to use mBridge, including firms in Xinjiang, to bypass US sanctions — a move that has drawn sharp criticism from Washington. The platform's ability to settle transactions in seconds without SWIFT or correspondent banks makes it a powerful tool for sanctions evasion and financial sovereignty.
Systemic Risks to the Dollar-Centric Order
The emergence of parallel digital currency corridors creates systemic risks for the dollar-centric global financial order. If mBridge and similar platforms achieve critical mass in trade settlement, the demand for dollar-denominated reserves could decline, potentially weakening the dollar's role as the world's primary reserve currency. The BIS's own research acknowledges that tokenized cross-border payments could reduce the demand for correspondent banking, which is heavily dollar-denominated.
However, the dollar's dominance is not easily displaced. The dollar accounts for 58% of global foreign exchange reserves and 88% of all foreign exchange transactions. mBridge's $55 billion in cumulative transactions, while impressive, remains small compared to the $2.3 trillion processed domestically by China's e-CNY ecosystem in 2025 alone. The dollar's liquidity, stability, and deep financial markets provide a buffer that no alternative currently matches.
Yet the trend is clear. The geopolitical implications of CBDC fragmentation extend beyond economics into the realm of financial statecraft, where control over payment infrastructure translates into geopolitical leverage.
Expert Perspectives
"mBridge is not designed to replace the U.S. dollar overnight, but it is building the infrastructure for a multipolar financial system," said Alisha Chhangani of the Atlantic Council. "The efficiency gains are so dramatic that even non-aligned countries are compelled to participate."
"The BIS's withdrawal from mBridge and launch of Project Agorá represents a recognition that digital currency standards are becoming geopolitical battlegrounds," noted a senior central bank official who spoke on condition of anonymity. "We are witnessing the birth of two competing financial architectures."
