Tariff Tremors: US-China Trade War Reignites, Rattling Global Markets

The spectre of a full-blown U.S.-China trade war has re-emerged with force. On April 5th, Beijing announced sweeping 34% tariffs on all U.S. imports, directly mirroring Donald Trump’s latest duties, which raise average U.S. tariffs on Chinese goods to a staggering 76% – the highest in over a century, per data from the Peterson Institute for International Economics. The result? Markets reeled globally.

The S&P 500 closed down 4.8%, the Stoxx 600 fell 5.1% (its sharpest single-day loss since 2020), and the FTSE 100 lost 5%, as investor sentiment collapsed. Brent crude slid 6.9% to $65.33/bbl, reflecting deep concerns over global demand and the risk of a synchronised slowdown.

A Strategic Decoupling – and Not Just in Rhetoric

This is no longer just brinkmanship. The scale and immediacy of China's retaliation – not only with tariffs but also with export restrictions on rare earth elements, an antitrust probe into DuPont’s China operations, and the blacklisting of U.S. tech firms – reflects a broader shift: the acceleration of strategic decoupling between the world’s two largest economies.

From an economic and diplomatic standpoint, China has moved from caution to confrontation. With communication channels between Beijing and Washington essentially frozen, the probability of near-term resolution is dwindling. What we are now witnessing is a paradox of pressure and pride – as one analyst aptly put it – with Trump wielding tariffs as a blunt-force policy tool, while Xi Jinping maintains a disciplined, if reactive, posture.

Investment Implications: Disruption, Dislocation, and Defensive Positioning

As a macro risk, this trade war now rivals early COVID-era disruption in terms of systemic impact. Global supply chains, already fragile from prior geopolitical tensions and reshoring trends, are being pulled further apart. Investors are now reassessing sectoral exposure with new urgency:

• Agriculture is a clear casualty. U.S. exports of soybeans, wheat and corn – heavily reliant on Chinese demand – face steep headwinds. According to Bloomberg, China imported over $14bn of U.S. agricultural goods in 2023; this is now under direct threat.

• Technology is entering a dangerous phase. Trump’s tariffs, combined with China’s blacklisting of drone makers and potential retaliations against firms like Apple and Tesla, threaten global supply chains. As tech analyst Dan Ives notes, this could set U.S. innovation back by a decade in key hardware sectors. Expect Chinese firms such as BYD and Huawei to absorb global market share, especially across the Global South.

• Rare Earths are a geopolitical flashpoint. China controls over 60% of global production and 85% of refining capacity. Restrictions here could cripple U.S. defence and tech supply chains – and send prices soaring, reviving interest in non-Chinese producers like MP Materials or Australian-listed Lynas Rare Earths.

• Capital Markets are behaving predictably: risk-off. U.S. Treasury yields fell sharply, with the 10-year down 13bps to 3.93%, reflecting a flight to safety. This is a classic case of defensive rotation: investors moving from equities into sovereign debt amid macro uncertainty.

MY VIEW: Beware the Feedback Loop

This is not a repeat of the 2018 trade war – the stakes are considerably higher. Trump has ratcheted tariffs far beyond his prior term, showing little concern for the market consequences. The average U.S. tariff rate on Chinese goods is now over 20x higher than pre-2018 levels. This, combined with parallel pressure on allies and traditional trading partners, risks catalysing a bifurcated global trade system.

From a private equity perspective, this environment introduces both headwinds and contrarian opportunities. Industrial companies with dual sourcing models and scalable domestic production stand to benefit. We are likely to see growing LP interest in funds targeting nearshoring, supply chain tech, and critical materials.

Meanwhile, for public market investors, volatility is set to persist. A tactical tilt toward defensive sectors (healthcare, consumer staples), energy infrastructure, and deglobalisation beneficiaries could outperform over the medium term.

Outlook: Prepare for Prolonged Hostilities

With both sides politically incentivised to maintain a hardline stance – Trump to project strength ahead of the election, Xi to avoid any perception of capitulation – this is likely to be a protracted conflict. And while China may be tactically reactive, its moves suggest long-term preparation for economic siege warfare.

We are entering a new era of economic nationalism, one where tariffs are a policy norm, not a negotiating chip. Investors would do well to position portfolios for a world where globalisation continues to retreat – and geopolitical risk becomes a primary driver of asset prices.
