Trump Reignites Trade War: 100% Tariffs and Software Controls Unleashed on China, Global Markets Reel

10 Min Read

US President Donald Trump has dramatically escalated trade tensions with China by announcing sweeping 100% tariffs on imports and new export controls on critical software, effective November 1st. This decisive move, a direct response to China’s recent restrictions on rare earth minerals, has sent global stock markets tumbling and reignited fears of a full-blown trade war with far-reaching implications for technology, manufacturing, and international diplomacy.

The fragile economic truce between the United States and China shattered on Friday as US President Donald Trump unveiled a formidable new set of trade restrictions. In a move that sent shockwaves across global financial markets, Trump declared an additional 100% tariff on Chinese imports and imposed strict new export controls on critical US software, both set to take effect on November 1st, 2025. This escalation marks the biggest rupture in relations between the two economic giants in six months, with profound implications for global trade, technology, and diplomatic relations.

The Spark: China’s “Aggressive” Rare Earth Maneuver

President Trump justified his actions by citing what he described as China’s “extraordinarily aggressive position on trade.” This refers to China’s recent decision to dramatically expand its export controls on rare earth elements and dozens of refining technologies, effective November 1st, 2025. China, which dominates over 90% of the world’s processed rare earths and rare earth magnets market, had previously tightened these restrictions. Rare earth minerals are indispensable materials for numerous high-tech products, ranging from electric vehicles and aircraft engines to military radars and advanced semiconductors.

Trump expressed his dismay at China’s actions, calling them “shocking” and a “hostile order.” He noted that China had seemingly aimed these controls at the entire world, not just the United States, and that he felt compelled “to financially counter their move.” This unilateral expansion of controls by Beijing was seen by Washington as a betrayal, ending an uneasy detente that had been established earlier in the year after painstaking diplomatic efforts.

Trump’s Retaliation: New Tariffs and Critical Software Blocks

A Staggering 100% Tariff on Imports

The centerpiece of Trump’s retaliation is the imposition of an additional 100% tariff on Chinese goods entering the United States. This new levy will be “over and above any Tariff that they are currently paying,” significantly increasing the cost of Chinese imports. For context, US tariffs on Chinese imports stood at 30% prior to this announcement, down from a peak of 145% earlier in the year. This drastic increase signals a severe escalation of the trade conflict, aiming to exert immense economic pressure on Beijing.

Export Controls on Critical US Software

Beyond tariffs, Trump also announced new export controls on “any and all critical software” by November 1st. Experts warn that restrictions on US software shipments to China could deliver a “massive blow” to the country’s burgeoning tech industry, particularly impacting sectors like cloud computing and artificial intelligence. This measure targets a strategic vulnerability for China, which heavily relies on foreign technology for its advanced computing infrastructure and AI development, further intensifying the tech rivalry between the two nations.

Global Markets Brace for Impact

The news immediately sent shockwaves through global financial markets, reigniting trade war fears and threatening to erase recent positive momentum. Investors swiftly fled into safe-haven assets like gold and US Treasury securities, while the US dollar weakened against a basket of foreign currencies, as reported by Reuters.

Wall Street’s Immediate Plunge

On Friday, Wall Street experienced a sharp sell-off. The S&P 500 and the Nasdaq composite recorded their worst single-day percentage drops since April 10th, shedding 2.71% and plunging 3.56% respectively. The Dow Jones Industrial Average also fell 1.90%. Shares of major tech companies, including Nvidia, Tesla, and Amazon, tumbled over 2% following the announcement, with tech stocks piling on losses in after-market trading.

Indian Markets Face Potential Sell-off

The ramifications are expected to extend to emerging markets, including India. Analysts predict that renewed trade tensions could dampen global risk sentiment, spurring dollar outflows and adding pressure on emerging market equities and currencies. The Sensex and Nifty, which had seen gains of nearly 1.5% the previous week, are anticipated to experience a sell-off or a gap-down opening on Monday. The Gift Nifty was already trading 0.78% lower, signaling potential volatility.

Expert Outlook: Volatility Ahead

Ponmudi R, CEO of Enrich Money and a SEBI-registered analyst, highlighted that the market’s direction in the coming week will hinge on a confluence of domestic factors, global macroeconomic trends, and corporate earnings. He emphasized that the “renewed escalation of the US–China tariff war… is expected to dampen global risk sentiment.” For the Indian market, he noted that the Nifty continues to show resilience, forming a higher-low structure above the crucial 25,000–24,850 zone. However, heavy call open interest between 25,300–25,400 presents a near-term hurdle, with a decisive close above 25,500 needed to reignite bullish momentum.

Ajit Mishra, SVP – Research at Religare Broking Ltd, advised investors to maintain a “buy-on-dips” approach above key support zones, deeming it prudent amidst the cautious optimism. He stressed the importance of a selective, stock-specific strategy, focusing on sectors likely to post robust Q2 results and prioritizing stocks demonstrating relative strength within their respective sectors.

Diplomatic Fallout: Xi Meeting in Doubt

The trade escalation has cast a shadow over diplomatic efforts. President Trump immediately called into question the prospects for a previously anticipated meeting with Chinese President Xi Jinping in South Korea, scheduled for three weeks from the announcement. While Trump initially posted on Truth Social that “now there seems to be no reason to do so,” he later clarified to reporters that he hadn’t formally canceled the meeting, saying, “I would assume we might have it.” Beijing has never publicly confirmed the meeting, further adding to the uncertainty surrounding this critical bilateral engagement.

Understanding the Strategic Stakes: Rare Earths and Tech Supremacy

China’s move to tighten export controls on rare earth minerals is a strategically significant escalation. These 17 elements are crucial for manufacturing everything from advanced electronics to renewable energy technologies. China’s near-monopoly on their processing gives it immense leverage in global supply chains and trade disputes. This action, coupled with Trump’s subsequent export controls on critical US software, underscores a deepening technological and economic rivalry where both nations are weaponizing their respective strengths to gain an advantage, as detailed by ABC News.

Looking Ahead: An Escalating Economic Rivalry

The latest tariff announcements and export controls signal a dramatic turn in the ongoing trade conflict between the US and China. This move is not merely about trade imbalances; it represents a broader struggle for technological dominance and geopolitical influence. The immediate market volatility serves as a stark reminder of how interconnected global economies are, and how rapidly political decisions can ripple through financial systems. As both sides dig in, the long-term implications for global supply chains, technological innovation, and international cooperation are likely to be profound and far-reaching, defining the economic landscape for years to come.
