The Bank of China's Shenzhen branch processed an outbound transfer of 11.3 billion yuan (approximately US$1.7 billion) in June with same-day finality. The following month, its Fujian branch received a Hong Kong dollar-denominated payment worth more than US$1.7 billion, settling the transaction in under 60 minutes. The July transaction represents the largest single transaction the platform has ever recorded; the June transaction marked a significant milestone in its own right. The bank said it "seeks to support companies' global operations and the international use of the yuan" through expanded mBridge services across additional currencies and regions.

What mBridge Is and How It Works

mBridge is a wholesale interbank settlement network, not a retail payment app. It allows central banks and their licensed commercial banks to transfer value directly to one another using national digital currencies, bypassing the chains of correspondent banks that traditional cross-border wires depend on. The platform runs on the mBridge Ledger, a custom blockchain using a Byzantine Fault Tolerant consensus protocol called HotStuff+. The ledger is also compatible with the Ethereum Virtual Machine, meaning developers with standard Solidity skills could, in principle, build settlement services on top of it subject to access rules set by member central banks. The BIS's June 2024 minimum viable product announcement explicitly invited private sector entities to participate, but the post-BIS governance structure under the five central banks has not publicly clarified whether that invitation remains active, a question of direct relevance to institutions exploring the platform's developer ecosystem.

Settlement on mBridge takes roughly 15 seconds. By comparison, SWIFT-routed payments typically clear in one to five business days. According to CleanSky.io, average transaction costs on the platform run around 0.3 percent, against an estimated 6.2 percent for a comparable SWIFT transfer.

The five full member institutions are the People's Bank of China, the Hong Kong Monetary Authority, the Bank of Thailand, the Central Bank of the UAE, and the Saudi Central Bank. More than 31 central banks hold observer status, including the Federal Reserve Bank of New York and the Banque de France. The Bank for International Settlements, which originally co-developed the project starting in 2021, formally withdrew on October 31, 2024, transferring governance entirely to the participating central banks.

China's digital yuan (e-CNY) accounts for an estimated 95 percent of total settlement volume on the platform.

Scale and Growth

The 600 billion yuan cumulative figure represents dramatic acceleration. An earlier benchmark, reported before the June and July milestone transactions, put total volume at roughly US$55.5 billion across more than 4,000 transactions. That earlier figure itself represented approximately 2,500 times the volume recorded during the 2022 pilot phase.

On the domestic side, the People's Bank of China reports that the e-CNY has now processed more than 3.4 billion transactions worth around 16.7 trillion yuan (approximately US$2.4 trillion), a figure more than 800 percent higher than 2023 totals. Effective January 1, 2026, China reclassified the e-CNY from a cash-like instrument to digital deposit money, allowing commercial banks to pay interest on digital yuan balances and embedding it more deeply into everyday banking.

Regional Implications

The platform's growth carries uneven consequences depending on geography.

For South Asia, the most immediate indirect effect runs through the Gulf. Saudi Arabia is a full mBridge member, and the Gulf states are the single largest destination for remittances sent by the roughly 35 million South Asian migrant workers based there. If wholesale settlement between Gulf banks and Chinese counterparties migrates to mBridge at scale, the fee structures underlying those remittance corridors could eventually shift. No retail-level deployment is confirmed, but India's Reserve Bank holds observer status, and New Delhi is simultaneously expanding its own UPI-based payment corridors, a hedging posture that reflects the broader geopolitical tension around the platform. Pakistan and Bangladesh, two countries with substantial Gulf remittance dependencies, are not confirmed as observer members and therefore sit outside direct influence on mBridge's technical governance.

For Africa, the stakes are structural. Around 80 percent of intra-African cross-border payments currently route through Europe or the United States via dollar correspondent chains. Four African central banks hold observer status on mBridge: the Bank of Namibia, the South African Reserve Bank, the Central Bank of Egypt, and the Bank of Mauritius. China is already the largest trading partner for both South Africa and Egypt. Standard Bank of South Africa has participated in e-CNY pilot programs, and earlier e-CNY settlements have been completed for commodities including precious metals and iron ore, two significant African export categories. Even so, analysts note that mBridge remains a wholesale interbank rail. African businesses and individual savers have no direct on-ramp. As one analyst summarised the structural gap: "mBridge solves the wholesale problem between states; it doesn't solve the retail problem of the Latin American or African saver." Dollar-pegged stablecoins such as USDT and USDC continue to dominate informal cross-border trade across Sub-Saharan Africa.

The Bigger Picture

The BIS's departure is widely seen as removing the main institutional voice arguing that mBridge was a neutral multilateral experiment rather than a geopolitical tool.

Former BIS General Manager Agustín Carstens stated before his organisation left the project that "the CBDC platform does not help BRICS countries evade sanctions" and that "mBridge is not the BRICS Bridge." Those assurances now come from a body with no seat at the governance table, a shift that observers say changes the institutional weight behind them.

Financial technology analyst Zennon Kapron argued in a May 2026 Forbes piece that the parallel stalling of Project Agorá, the BIS-backed effort to link commercial bank deposits across participating jurisdictions, effectively ends the prospect of a single global CBDC interoperability standard. What remains, Kapron wrote, is a world where digital currency infrastructure is forming in distinct geopolitical blocs rather than converging on shared rails.

For the countries and institutions still deciding where to position themselves, the window for neutral observation may be narrowing faster than the pace of official deliberations.
