China is building the financial infrastructure of a post-dollar world

China is not seeking to dethrone the dollar, but it is trying to make its use less indispensable. For several years, Beijing has been investing heavily in a new generation of financial infrastructure built around the digital yuan and cross-border settlement networks designed to operate outside the traditional channels dominated by the United States.

By the end of 2025, cumulative transactions conducted in China’s digital yuan had exceeded 16.7 trillion yuan, or approximately $2.3 trillion. At the same time, mBridge, the cross-border settlement platform based on central bank digital currencies, had already processed more than 4,000 transactions worth nearly $55.5 billion.

Taken in isolation, these figures do not threaten the dollar’s dominance. Together, however, they reveal a coherent strategy: China is gradually building the financial infrastructure of a world in which international trade would no longer systematically depend on US financial rails.

This development is often analysed as a monetary issue, but it is primarily an infrastructure strategy. As with semiconductors, cloud computing, energy and artificial intelligence, Beijing is seeking to control the technical layers that allow the system to function. The real question is who will control the networks through which money circulates.

Behind the dollar lies an infrastructure

To understand China’s strategy, we must first understand what Beijing is actually trying to bypass. The term “US financial rails” does not refer to a single infrastructure. It describes the full range of technological, financial and legal layers through which international payments move.

When a Brazilian company buys oil from a Saudi supplier, or an Asian manufacturer pays a European vendor in dollars, the money does not travel directly from one bank account to another. Transactions generally pass through several intermediaries: correspondent banks, financial-messaging networks, clearing infrastructure and institutions with direct access to the US financial system.

This architecture has developed gradually since the end of the Second World War and now represents one of the United States’ principal sources of economic power.

The dollar’s dominance rests on four complementary layers.

The first is the currency itself. A substantial share of international trade continues to be denominated in dollars, even when the United States is not involved in the transaction.

The second consists of correspondent banks. To make international payments in dollars, many foreign banks still depend on institutions with direct access to the US financial system.

The third comprises the clearing and settlement infrastructure that processes trillions of dollars in transactions every day.

The fourth and final layer is legal. Once a transaction passes through the dollar system, it may fall under US jurisdiction, even when both parties are located outside the United States. This mechanism notably enables the extraterritorial enforcement of many financial sanctions.

This distinction is essential because China is not necessarily seeking to persuade the world to abandon the dollar. Its objective is more pragmatic: to create infrastructure that allows certain international transactions to operate without systematically depending on US correspondent banks, US clearing systems or US financial jurisdiction.

In other words, Beijing considers it easier to build alternative roads than to replace the dominant currency.

The digital yuan becomes an infrastructure tool

Long presented as a technological experiment, the e-CNY is gradually becoming a permanent component of China’s financial architecture.

The digital yuan is not intended to replace Alipay or WeChat Pay, which dominate everyday payment usage. The authorities’ objective is to establish a public digital-payment infrastructure directly connected to the banking system.

The digital yuan is already being used to distribute certain forms of public assistance, tax refunds, social benefits and pilot consumer incentives. A new governance and assessment framework came into force in early 2026 to integrate the e-CNY more deeply into the domestic financial system.

The authorities are also experimenting with mechanisms that would allow certain digital-yuan deposits to earn interest. This suggests that the People’s Bank of China no longer regards the e-CNY as a simple pilot project, but as a lasting component of the country’s monetary architecture.

As the use of cash declines, the digital yuan gives the state a sovereign payment rail whose principal components it controls. This development serves domestic objectives, but it is also laying the foundations for international use.

mBridge moves from laboratory to infrastructure

That is precisely the ambition behind mBridge. The project emerged from cooperation among several central banks seeking to test the use of central bank digital currencies for cross-border settlements.

The idea is to allow financial institutions to settle international transactions in real time without systematically relying on traditional correspondent-banking mechanisms.

The first tests conducted in 2022 involved limited volumes. At the time, fewer than 200 transactions worth approximately $22 million were completed. Three years later, the scale had changed radically.

By the end of 2025, the platform had processed more than 4,000 transactions worth approximately $55.5 billion. According to data published by participants, more than 95% of those volumes were reportedly settled in digital yuan.

The Bank for International Settlements’ withdrawal from the project’s operational governance at the end of 2024 represented an important turning point. It marked the transition from a research experiment to infrastructure intended for real-world use.

The platform has already taken another step forward. At the end of 2025, the United Arab Emirates conducted a government transaction through mBridge, demonstrating that the system could be used for official operations rather than merely technical trials.

Although mBridge will not become a global alternative in the short term, it demonstrates that a parallel settlement architecture can function.

Building corridors rather than conquering the world

Contrary to some alarmist interpretations, Beijing does not appear to be seeking to impose the digital yuan on the entire planet. Its objective is to develop specific trade corridors in which the use of dollar-dominated infrastructure becomes optional.

This strategy is particularly visible in trade between China, the Gulf states, certain Asian economies and several Belt and Road partners. For the companies involved, the advantages are tangible: fewer intermediaries, faster settlement, lower transaction costs and permanently available infrastructure.

The digital yuan then becomes less a currency than a settlement protocol. The history of networks shows that infrastructure is rarely adopted universally from the outset. It generally spreads corridor by corridor, use case by use case and market by market. China’s strategy appears to follow the same logic.

Energy as a path to expansion

Energy could become one of the principal channels through which this strategy spreads. Historically, the dollar’s international role has relied heavily on the global trade in hydrocarbons. Energy flows remain one of the foundations of international finance.

mBridge officials now explicitly identify settlements related to international trade, commodities and energy as priority use cases. China is therefore exploring the creation of alternative channels for certain transactions.

The objective is not to replace the petrodollar overnight. The gradual proliferation of energy settlements conducted through alternative infrastructure could, however, help reduce some participants’ dependence on traditional channels.

The transformation would be incremental: a handful of contracts today, regional corridors tomorrow and specialised networks over the longer term.

De-dollarisation could therefore begin with infrastructure before affecting the currencies themselves.

Three visions for the future of money

This development highlights three distinct approaches.

The United States favours a model based on private-sector innovation, in which stablecoins are gradually emerging as a digital extension of the dollar distributed by technology and financial companies. The US strategy is less about building a public digital currency than allowing the market to circulate the dollar in a new form.

China, by contrast, favours a sovereignty-driven model in which infrastructure is treated as a strategic asset integrated into a broader industrial, technological and geopolitical policy.

Europe is adopting a more defensive approach. Discussions surrounding the digital euro are principally intended to preserve the existence of public money in an environment dominated by private platforms and foreign infrastructure.

Similar technologies therefore conceal profoundly different visions of the role of money.

An infrastructure battle before a currency battle

It would be premature to announce the dollar’s decline. No other currency currently benefits from a financial ecosystem comparable to that of the United States. US markets remain the centre of gravity of the global monetary system, while Treasury securities continue to serve as the benchmark asset of international finance.

The question raised by the digital yuan and mBridge is instead one of infrastructure diversification. For several decades, globalisation has relied on networks largely dominated by the United States. China is now applying to finance the same strategy it has already pursued in semiconductors, telecommunications, cloud computing and artificial intelligence: reducing critical dependencies and building its own capabilities.

A post-dollar world will probably not be a world without the dollar. It could, however, become one in which the dollar remains dominant without being systematically indispensable.

This is precisely why the significance of the digital yuan and mBridge now extends far beyond monetary policy. They mark the emergence of a new competition, no longer merely over control of currencies, but over the infrastructure that allows those currencies to circulate.
