While the diplomatic spotlight often focuses on high-profile summits and military posturing, the most immediate impact of the US-China rivalry is unfolding in global markets—in the decisions of traders, investors, supply chain managers, and CEOs worldwide. As the world’s two largest economies recalibrate their relationship, global financial systems are absorbing the shockwaves in complex and often underappreciated ways.
From commodities pricing to currency volatility, tech sector investment to the shifting dynamics of emerging markets, the economic undercurrents of geopolitical tension are already reshaping how global markets function. The effects may be subtle in the day-to-day, but their cumulative impact will define the architecture of international finance and trade for years to come.
In this article, we’ll explore how key sectors of global markets are responding to the deepening US-China rivalry—from commodities to currencies, technology to capital flows—and what to watch in the years ahead.

Commodities Markets: Supply Chains Under Strain
One of the most tangible ways the US-China rivalry is reshaping global markets is through commodities and supply chains.
As both powers push toward strategic decoupling, markets for critical materials have become volatile. The race for rare earth elements—essential for advanced electronics and defense systems—has intensified. With China still dominating rare earth processing, Western buyers are scrambling to diversify supply, driving investment into Australia, Canada, and parts of Africa.
Lithium, the backbone of EV batteries, is similarly affected. China’s aggressive investments in Latin America’s Lithium Triangle (Argentina, Bolivia, Chile) are forcing Western automakers and battery producers to forge alternative supply partnerships. Meanwhile, geopolitical risk premiums are now priced into copper markets as Chile and Peru, key suppliers, face competing pressures from both Beijing and Washington.
Semiconductors remain at the heart of US-China tensions. US export restrictions on advanced chipmaking tools to China have not only disrupted China’s tech ambitions, but have also triggered realignments in global semiconductor supply chains. Countries like Vietnam, Malaysia, and Mexico are emerging as new hubs for chip assembly and packaging, a trend that is slowly shifting global trade patterns.
The result is an evolving map of supply chain configurations, with Latin America and Southeast Asia gaining prominence as alternative sourcing regions. However, this transition is costly and complex—one reason why commodity markets remain so sensitive to geopolitical headlines tied to the US-China rivalry.
Currencies: The Shifting Landscape of Global Payments
While trade wars and tariffs grab headlines, the US-China rivalry is also accelerating deeper changes in global currency markets.
A major front is yuan internationalization. In response to US sanctions and restrictions on dollar-based payments, China has expanded the use of its digital yuan and bilateral currency swap agreements—particularly with Global South partners. In Africa, several countries are now settling portions of Belt & Road project payments in yuan. In Latin America, deals denominated in yuan—especially in commodities and energy—are slowly gaining ground.
At the same time, a number of emerging economies are diversifying foreign exchange reserves, reducing overreliance on the US dollar. While the dollar remains dominant, its share in global FX reserves has slipped marginally—reflecting a broader strategic hedging by some nations concerned about geopolitical weaponization of finance.

For forex markets, this dynamic introduces new volatility—particularly in emerging markets. As more countries experiment with multi-currency trade settlements, fluctuations in yuan-dollar exchange rates have broader spillover effects.
Meanwhile, in certain regions, the search for currency alternatives has spurred rising interest in crypto assets. In Argentina, Nigeria, and parts of Southeast Asia, crypto is being used both for capital flight hedging and as a workaround for capital controls tied to US-China financial tensions.
Tech Stocks and Investment Flows
Perhaps no sector of the global market is more directly exposed to US-China tensions than technology.
US restrictions on China’s tech sector—from chip bans to investment blacklists—have caused ripples across global tech stocks. Semiconductor companies with major China exposure saw sharp valuation adjustments following each new round of US Commerce Department controls.
In response, global investors are rethinking tech portfolios. There is growing preference for US-aligned markets—with India, Vietnam, Singapore, and Japan attracting fresh capital inflows in AI, semiconductors, and cloud services.
For Chinese tech giants, adaptation is key. Firms like Huawei and Alibaba are pushing aggressively into Global South markets, seeking to offset Western restrictions with new revenue streams in Africa, Southeast Asia, and Latin America. Meanwhile, Chinese venture capital is increasingly flowing into Belt & Road-linked AI startups—shaping an alternative ecosystem outside of US regulatory reach.
At the same time, US tech companies are recalibrating China strategies. While Apple, Tesla, and Qualcomm remain deeply invested in the Chinese market, they are hedging bets—expanding manufacturing footprints in India and Mexico, and diversifying supplier bases.
All of this is translating into greater dispersion in global tech valuations and a more fragmented outlook for cross-border investment flows in the digital economy.
Emerging Markets: Caught Between Two Giants
For many emerging markets, the deepening US-China rivalry is both a risk and an opportunity.
Countries in ASEAN, Africa, and Latin America are increasingly being viewed through the lens of geopolitical alignment—and investors are adjusting country risk premiums accordingly. Those perceived as leaning toward US alliances are often seeing capital inflows tied to friend-shoring and supply chain diversification. Vietnam, Malaysia, and India have all benefited.
Conversely, markets more closely integrated with China’s economic orbit—such as Cambodia, Laos, parts of Sub-Saharan Africa—are attracting Belt & Road-linked investment, but also face rising scrutiny from Western investors wary of geopolitical risk exposure.
A new dynamic is emerging: the “China premium” versus “US alignment discount”—a reflection of how global capital is now pricing in the strategic choices of emerging economies.
At the same time, Global South markets are leveraging this competition. Many governments are adeptly extracting better terms from both sides—winning infrastructure finance from China while securing trade deals and market access from the US and Europe.
The fluidity of this landscape means that capital flows into emerging markets remain highly sensitive to shifts in US-China relations—a reality that global investors are watching closely.
