The U.S. equity markets endured their worst single-day selloff since April 2025 on Friday, following a series of renewed trade threats between President Donald Trump and China. The Dow Jones Industrial Average plunged over 870 points, or 1.9%, to close below the 45,200 mark. The S&P 500 shed 2.7%, while the tech-heavy Nasdaq Composite nosedived 3.6%, underscoring intense anxiety among investors about the future of U.S.-China relations and their impact on the global economy.

The selloff was triggered by President Trump’s aggressive social media posts in which he threatened a “massive increase” in tariffs on Chinese imports. This escalation came only hours after China rolled out fresh trade countermeasures, including increased port fees on U.S. cargo and the launch of a high-profile antitrust investigation into American semiconductor giant Qualcomm.

Trade War Heats Up

Friday marked a dramatic escalation in trade tensions between the world’s two largest economies. The current standoff began after China imposed a series of punitive measures designed to strike at strategic sectors of the U.S. economy, including technology and agriculture. In addition to the new regulatory hurdles placed before Qualcomm and tighter export controls on rare earth minerals, Beijing also announced a suspension of all soybean purchases from American producers—worsening an already strained outlook for U.S. farmers.

In response, President Trump intensified his rhetoric. “One of the policies that we are calculating at this moment is a massive increase of tariffs on Chinese products coming into the United States of America,” he posted on Truth Social, raising the specter of even more aggressive protectionist measures.

The president’s planned meeting with Chinese leader Xi Jinping at the Asia-Pacific Economic Cooperation (APEC) summit in South Korea was canceled, further dashing hopes of a diplomatic breakthrough.

Wall Street’s Sharp Reaction

The major indices opened the session with modest gains, but rapidly lost ground mid-day as the tit-for-tat escalated and it became clear that the standoff could drag on. The decline sent the Dow tumbling more than 870 points at the close, the S&P 500 to 5,115, and the Nasdaq to 15,535.

• Dow Jones Industrial Average: -1.9% (down 870 points)
• S&P 500: -2.7%
• Nasdaq Composite: -3.6%

Tech stocks—particularly semiconductors and companies reliant on Chinese supply chains—suffered outsized losses. Qualcomm shares fell more than 7%, while other tech giants like Apple and Nvidia also retreated sharply. Chinese tech giants including Alibaba, Baidu, and Tencent also suffered, with some stocks down more than 6% on the Hong Kong exchange.

The selloff was not limited to equities: risk aversion fueled declines in cryptocurrencies as well. Bitcoin fell below $118,000, losing nearly 3%, while Ether dropped 6% in sync with the broader market rout.

Commodities and Fixed Income Market Response

The heightened geopolitical tensions also reverberated through commodity markets. Oil prices extended their weekly declines as the threat of weaker global growth overshadowed earlier worries about Middle Eastern supply disruptions. Brent crude dropped 3% to $78 per barrel, while West Texas Intermediate matched the decline, closing near $74 per barrel. Concurrently, the approval of a tentative ceasefire plan in Gaza shifted focus away from immediate energy supply risks.

Meanwhile, U.S. Treasury yields retreated as investors sought safety. The benchmark 10-year Treasury dropped 5 basis points to 4.09%, while the 30-year yield slid to 4.67%. According to Apollo Global, almost 90% of the world’s public fixed income is now yielding below 5%, highlighting diminishing real returns for investors as inflation remains above 3%.

Broader Economic Concerns: Government Shutdown and Consumer Sentiment

Friday’s sharp decline closed out a week already marred by mounting economic uncertainty. With the U.S. government shutdown entering its 10th day, official economic data releases such as jobs reports and inflation readings remained on hold. This increased reliance on private data and contributed to market unease. The University of Michigan’s preliminary consumer sentiment index for October hovered at 55—well below 2024 levels—indicating ongoing anxiety about inflation and job prospects among U.S. households.

Economists note that long-term inflation expectations have remained steady at around 3.7%, but worry that persistent uncertainty over trade, government funding, and global growth could further dampen consumer and business confidence heading into the final quarter.

Corporate and Sector Highlights

• Qualcomm: Shares dropped over 7% after China announced an antitrust investigation into its $5.1 billion acquisition of Israeli chipmaker Autotalks, deepening regulatory woes for U.S. tech firms in China.
• Levi Strauss: Despite raising its full-year profit guidance, the denim giant’s shares slumped almost 7% as ongoing tariffs weighed heavily on outlook.
• Rare Earth Miners: In a rare bright spot, shares in U.S. rare earth producers like MP Materials and USA Rare Earth jumped 15% following heightened awareness about the U.S.’s dependency on Chinese supply chains for strategic minerals essential to electronics, defense, and technology sectors.
• Commodities: Cocoa futures continued an eight-week losing streak—its worst since 1999—amid excess supply and weaker demand from confectionery makers.

What’s Next for Markets?

Investors are bracing for a volatile start to the Q3 earnings season, with major financial institutions such as JPMorgan and Citigroup expected to report next week. Analysts widely anticipate that ongoing tariffs will further squeeze quarterly revenue across the S&P 500, particularly in global-facing industries like tech and manufacturing.

The market’s rapid decline underscores the sensitivity of global equities to geopolitical news and policy uncertainty. With no imminent resolution to either the U.S.-China trade conflict or the federal government shutdown, risk and volatility are likely to persist. Analysts advise maintaining a cautious outlook and close attention to further policy developments and company earnings in the coming weeks.
