From petro-dollar to tech-yuan: the real trade behind China’s rise

The global economy is changing shape. Geopolitical tensions, wars, sanctions and shifting alliances are accelerating a transition toward a more fragmented and multipolar world.

• The dominance of the United States remains immense, but the blind trust that once underpinned the US-centric financial system is slowly eroding.
• The rise in US debt, repeated geopolitical frictions and the increasing use of sanctions as a political tool are encouraging many countries to rethink their economic dependencies.
• Countries decrease exposure to US.

And among the countries positioning themselves for this new era, China stands out.

For years, China participated in a global system largely designed around the US dollar and American economic power. Today, it is increasingly building alternatives. Not overnight, not aggressively, but steadily and strategically.

And that shift is creating investment opportunities.

For decades, global trade operated around a relatively simple mechanism: oil was priced and traded in US dollars, and the revenues generated by oil-exporting nations were often recycled into US assets, especially US Treasuries.

This created the so-called “petrodollar” system.

This US-dollar centric system strengthens global demand for the dollar, reinforces the role of US financial markets and helps cement America’s position at the centre of the global economy.

Major oil producers, OPEC members and international financial institutions all contribute to maintaining this framework. The result is a powerful cycle where trade, finance and reserve management continuously supported the dollar’s dominance.

But global systems evolve. And today, China is gradually rewriting part of that playbook.

Over the past few years, an increasing share of trade — from oil to industrial commodities — has started to be settled in Chinese yuan instead of US dollars.

China has expanded bilateral agreements with key trading partners, strengthened financial links across Asia, the Middle East and Africa, and encouraged settlement outside the traditional dollar-based system.

This trend accelerated further as geopolitical tensions increased.

• China has notably continued buying oil from countries facing Western sanctions, including Russia and Iran, often using yuan-based settlement mechanisms.
• At the same time, Beijing has deepened commercial ties through initiatives like the Belt and Road Initiative — the modern version of the Silk Road designed to expand infrastructure, trade corridors and economic influence far beyond China’s borders.

As a result, the idea of the “petro-yuan” has gained traction.

While still far from replacing the dollar globally, the trend itself matters because it reflects a broader shift in economic power dynamics.

And importantly for investors, it creates new ways to think about global capital flows.

At first glance, trading the rise of the petro-yuan may seem straightforward: simply buy the Chinese currency.

But in practice, the yuan is not an easy macro trade.

There are actually two versions of the Chinese currency.

• The first is the onshore yuan, or CNY, traded within mainland China under strict capital controls and within a managed trading band set by the People’s Bank of China.
• The second is the offshore yuan, or CNH, traded mainly in Hong Kong, London and Singapore. This version is more flexible and reacts more directly to global market sentiment and international trade flows.

However, even the offshore yuan remains heavily influenced by policy decisions and does not behave like freely floating currencies such as the euro, yen or British pound.

Volatility remains relatively contained, policy intervention is frequent and directional moves are often gradual rather than explosive.

This means that while the petro-yuan narrative may be gaining momentum, the foreign exchange market does not necessarily provide a clean or efficient way to express that view.

So investors need to look elsewhere.

If countries reduce their reliance on the US dollar, they do not automatically replace it with another currency.

Instead, many central banks are increasing their gold reserves.

This trend has become increasingly visible in recent years as geopolitical fragmentation deepened and trust in the neutrality of reserve currencies weakened.

Gold offers something unique: it is not tied to the economic policies or political system of a single country. It is a supranational asset.

China has actively encouraged this trend

- by central bank purchases: the People’s Bank of China is replacing US Treasury holdings by gold,

- by developing its own gold ecosystem: some trade partners receiving yuan revenues from trade with China are increasingly able to convert part of those proceeds into gold and store it in Shanghai-based vaults.

This matters because it helps solve one of the structural limitations of the yuan: countries may hesitate to accumulate large yuan reserves, but they are often far more comfortable holding gold.

As a result, one of the clearest ways to position for gradual de-dollarisation may not be through the yuan itself, but through gold.

But gold is only part of the story.

Because not all yuan received through trade gets converted into gold. A growing share gets reinvested into China’s own economic ecosystem.

This is where the story becomes much more interesting.

Countries export oil, raw materials or manufactured goods to China and receive yuan in return. Those yuan are then increasingly used to purchase Chinese goods, services and financial assets.

In other words, the yuan flows out — and then flows back in.

That creates a powerful feedback loop.

The more trade that is settled in yuan, the more liquidity remains within China’s financial system. Over time, this can 

• support domestic demand, 
• deepen capital markets and 
• reinforce China’s broader economic influence.

This is why the most important question may not be “How do I trade the petro-yuan?”

The better question could be: “Where does the yuan end up?”

And increasingly, the answer is: Chinese markets.

Many investors still associate China with low-cost manufacturing and cheap exports. But that image is becoming increasingly outdated.

China is moving aggressively up the value chain.

Today, the country is exporting

• electric vehicles,
• batteries, 
• solar panels,
• semiconductors, 
• consumer electronics and
• increasingly advanced technology products. It is also becoming a major player in artificial intelligence infrastructure and industrial automation.

China’s clean energy ecosystem has expanded rapidly, supported by large-scale investments in solar power, wind energy and battery technology.

This matters because the global energy transition itself is becoming one of the most important economic themes of the coming decades.

And China sits at the centre of it.

The country is not only producing cheap manufactured goods anymore — it is increasingly exporting technology and energy-transition infrastructure.

In that sense, the story goes far beyond the petro-yuan.

It is becoming a “tech-yuan” story.

Chinese technology companies remain significantly cheaper than many US and Asian counterparts, especially after years of regulatory crackdowns, geopolitical tensions and slowing domestic growth.

For investors, this creates opportunities — but also important risks.

Companies like Alibaba, Tencent and Baidu continue to play major roles in e-commerce, cloud computing, artificial intelligence and digital ecosystems. At the same time, Chinese industrial and clean-tech champions continue expanding globally.

However, investing in China requires caution.

• Government intervention remains a major risk factor.
• The property sector continues to struggle,
• Demographic trends remain challenging and
• Competition in sectors like electric vehicles is creating intense pricing pressure.

The Hang Seng Index, heavily exposed to Chinese technology and growth companies, is still recovering from the deep selloff seen between 2018 and 2023.

But that is also part of the argument.

What we are witnessing is not necessarily the collapse of the US dollar or the end of American dominance.

The United States remains the world’s largest economy and the dollar remains the dominant reserve currency.

But the world is gradually becoming more multipolar.

And this transition is reshaping investment opportunities.
