Trump to hike China tariffs to 130% and impose software export controls next month, as trade war reignites to nearly ‘Liberation Day’ levels

President Trump announced a new 100% tariff on China, effective November 1, 2025, and export controls on critical software, significantly escalating the trade war in direct response to China's restrictions on rare earth exports. This move, which would bring total tariffs to 130%, triggered a 2.7% plunge in the S&P 500 and caused grain prices to fall as prospects for a U.S.-China trade deal diminished. The escalation underscores a deteriorating bilateral relationship, marked by China's recent retaliatory measures including port fees, an antitrust probe into Qualcomm, and new rare earth export licensing requirements.

Analysis

President Trump announced a new 100% tariff on China, effective November 1, 2025, alongside export controls on critical software, significantly escalating the trade war. This action, which would bring total U.S. tariffs on China to 130%, is a direct response to China's restrictions on rare earth exports, a critical mineral supply where China holds over 90% of global processing capacity. The move signals a hardening stance after a period of perceived easing in trade relations.

The market reacted sharply, with the S&P 500 plunging 2.7%, its worst selloff since April's trade war peak, reflecting investor concern over renewed tensions. Grain prices also fell following Trump's suggestion of not meeting President Xi, diminishing hopes for a trade deal that would include Chinese purchases of U.S. soybeans. This indicates a potential long-term impact on agricultural exports.

This escalation follows a series of reciprocal actions, including U.S. port fees met with similar fees by Beijing, China's antitrust investigation into U.S. chipmaker Qualcomm, and new rare earth export licensing requirements from China starting December 1. The deteriorating relationship suggests a broader economic and technological conflict beyond traditional tariffs, impacting global supply chains and specific industry sectors.

Key Decisions for Investors

• Investors should prepare for sustained U.S.-China trade tensions and potential supply chain disruptions, particularly in sectors reliant on rare earths and critical software.
• Monitor for further retaliatory measures from both nations, as the current environment suggests a tit-for-tat escalation cycle that could impact market stability.
• Re-evaluate exposure to companies with significant revenue or supply chain dependencies in China, especially those in technology and agriculture, given the increased tariff burden and export controls.
