China’s Digital Payment System Is Challenging the Dollar — What UK Investors Need to Know

The US dollar has dominated global trade and finance since the end of World War Two. It underpins everything from oil contracts to international debt. But China has spent the past decade quietly building an alternative: a digital currency and cross-border payment network designed to reduce the world’s dependence on the dollar. In 2026, that project is accelerating — and the implications reach far beyond China’s borders, including to the UK.

What Is China’s Digital Payment System?

China is running two parallel financial infrastructure projects aimed at challenging dollar dominance. The first is the e-CNY, China’s central bank digital currency (CBDC) also known as the digital yuan. The second is CIPS — the Cross-Border Interbank Payment System — which is China’s answer to SWIFT, the Western network that processes most international bank transfers.

The e-CNY is issued and controlled by the People’s Bank of China (PBOC). It functions like digital cash but is directly backed by the central bank, not a commercial bank. Unlike cryptocurrencies such as Bitcoin, it is not decentralised — the PBOC has full visibility and control over all transactions. On 1 January 2026, a major upgrade took effect: e-CNY wallets now pay interest, making the digital yuan function more like a bank deposit than physical cash. This change significantly increases its appeal as a store of value.

CIPS, meanwhile, is the payment rail that moves money across borders in Chinese yuan. It is the infrastructure layer — the pipes through which international yuan transactions flow between banks in different countries. As of May 2025, CIPS had 1,683 participating institutions, a 10% year-on-year increase, and processed over ¥175.49 trillion (approximately $24.45 trillion) in 2024. That scale is substantial, though still dwarfed by SWIFT’s daily volumes.

How Big Is the Digital Yuan Already?

By November 2025, the e-CNY had processed 3.48 billion transactions worth 16.7 trillion yuan — approximately $2.37 trillion in total volume. That is a significant number, but the important context is that the vast majority of those transactions are domestic. The real challenge for China is extending digital yuan usage beyond its own borders, where the dollar’s grip is strongest.

To address this, China launched a dedicated Shanghai International Operations Centre in September 2025, specifically focused on cross-border e-CNY use cases. Pilot programmes with Singapore, Thailand, Hong Kong, the UAE, and Saudi Arabia are now active or in development. These are not symbolic gestures — they represent concrete testing of yuan-settled trade outside China’s domestic market.

In December 2025, the PBOC updated CIPS rules to reduce dependence on SWIFT messaging for final settlement. This is a technical but strategically significant move: it means yuan payments can increasingly flow between countries without passing through Western-controlled financial infrastructure.

Why Is China Doing This?

The motivation is partly economic and partly geopolitical. Dollar dominance gives the United States enormous power. When the US imposes financial sanctions — as it did on Russia in 2022 — it can cut countries off from the global payment system by denying access to SWIFT and freezing dollar reserves. China has watched this happen and drawn a clear conclusion: any country heavily dependent on dollar infrastructure is exposed to American political decisions.

For China, reducing dollar dependence is a matter of financial sovereignty. A world where more trade is settled in yuan, through CIPS, using e-CNY technology, is a world where American sanctions become less effective. Russia’s exclusion from SWIFT in 2022 actually accelerated CIPS adoption among sanctioned and sanction-wary nations. By March 2026, Russia and Iran had settled $214 billion in trade using Chinese yuan — direct evidence that the alternative infrastructure is being used in practice, not just theory.

The numbers at the BRICS level tell a similar story. Trade between BRICS nations exceeded $1 trillion in 2025, with approximately 67% of payments made in local currencies — primarily yuan. The dollar’s share of BRICS internal trade has declined sharply compared to five years ago.

CIPS vs SWIFT: What’s the Difference?

SWIFT is a messaging network used by over 11,000 financial institutions in more than 200 countries. It does not move money itself — it sends secure messages between banks confirming payment instructions, which are then settled through correspondent banking relationships often involving the US dollar. SWIFT’s dominance is partly structural: because so many transactions are dollar-denominated, they must eventually pass through the US banking system.

CIPS is both a messaging network and a settlement system, and it settles in yuan rather than dollars. Its current limitation is scale — 1,683 participants versus SWIFT’s 11,000+ — and the fact that most global trade contracts are priced in dollars, not yuan. Switching from dollars to yuan requires not just a payment system but a shift in how commodities, shipping, and debt are priced globally. That is a much slower process.

The honest assessment is that CIPS is not replacing SWIFT any time soon. What it is doing is creating a credible alternative for countries that want one — particularly those facing Western sanctions, those in the BRICS bloc, and those in Asia, Africa, and the Middle East with growing trade ties to China. The system does not need to replace SWIFT globally to be strategically significant. It only needs to be viable enough that countries have a choice.

What Has the UK Got to Do With This?

The UK is not a BRICS member and its trade with China, while substantial, is conducted primarily in dollars and pounds. However, UK investors and businesses are affected by global dedollarisation trends in several important ways.

UK pension funds and investment portfolios hold large quantities of dollar-denominated assets — US Treasury bonds, US equities, dollar-priced commodities. If dollar demand gradually declines as more global trade settles in yuan or other currencies, the dollar could weaken over long timeframes. A weaker dollar affects the value of those assets when converted back to pounds.

UK businesses exporting to China or Southeast Asia may eventually find it advantageous — or necessary — to accept yuan-denominated payment. CIPS is expanding into Southeast Asian markets where UK companies do significant business. The practical implications are still years away for most UK exporters, but multinational firms are already evaluating exposure.

The UK is also developing its own CBDC — the digital pound, known internally as the “Britcoin” project — being led by the Bank of England and HM Treasury. The UK’s digital pound would serve a different purpose to China’s e-CNY (domestic retail payments rather than geopolitical leverage), but the trajectory of China’s digital currency system is shaping global thinking about what CBDCs can and should do.

Is the Dollar Actually in Danger?

The short answer is: not immediately. The dollar’s dominance is deeply embedded in global financial infrastructure, treaty relationships, commodity pricing, and the sheer size of US capital markets. No other currency — including the yuan — offers the depth of liquid assets, the rule of law backstop, or the universal acceptance that the dollar provides.

The yuan has specific structural weaknesses that limit its global appeal. China’s capital account is not fully open, meaning foreign investors cannot freely move money in and out of China. The yuan’s value is managed by the PBOC, not freely floating. And the legal and political systems underpinning yuan-denominated contracts do not offer the same protections that dollar contracts backed by US courts do. These are significant disincentives for international investors and trading partners.

What China is building is not a replacement for the dollar in one dramatic shift. It is a parallel system that reduces friction for countries that want to trade with China in yuan. Over decades, if that system matures, if China’s capital account gradually opens, and if more commodity contracts are priced in yuan, the dollar’s dominance could erode from the edges. The International Monetary Fund estimated in 2025 that the dollar’s share of global foreign exchange reserves had fallen from 73% in 2001 to approximately 57% by late 2025 — a decline that has been slow but consistent.

What This Means for UK Investors

The practical implications for UK investors in 2026 are limited but worth monitoring. If you hold significant exposure to the US dollar — through US equity funds, dollar-denominated bonds, or commodity investments — the long-term trajectory of dedollarisation is a background risk rather than an immediate threat. Most financial advisers would not recommend restructuring a portfolio around this theme alone, but it is a factor in the broader macroeconomic picture.

For UK investors interested in crypto, there is an indirect angle: if dollar hegemony weakens, the case for Bitcoin as a neutral, non-sovereign store of value becomes stronger, not weaker. Some analysts argue that the dedollarisation narrative is one of the structural tailwinds behind Bitcoin’s increasing adoption by institutional investors and nation-states. El Salvador, for example, has pointed to dollar dependency as a reason for adopting Bitcoin as legal tender.

More immediately, UK businesses trading in Asia should monitor CIPS expansion. By 2027 or 2028, accepting yuan payments through CIPS infrastructure may become a practical commercial question for companies with significant exposure to Chinese supply chains or customers.
