Rare Earths for Chips: Navigating the U.S.-China Trade Talks for Strategic Gains

As the August 2025 U.S.-China tariff deadline looms, the interplay of rare earth minerals and semiconductors has become the epicenter of a geopolitical standoff with profound implications for global supply chains. Companies positioned to navigate this volatility through diversified supply chains, long-term contracts, or critical mineral vertical integration stand to reap outsized rewards. Here's how investors can capitalize on the shifting dynamics.

The Rare Earth-Semiconductor Nexus

Rare earth elements (REEs) are the unsung heroes of modern technology. They are critical for manufacturing semiconductors, electric vehicle (EV) motors, and defense systems. For instance, neodymium and dysprosium are essential for the permanent magnets in EV motors, while lithium powers batteries. The U.S., however, remains dangerously dependent on China, which controls 60% of global rare earth production and 90% of refining capacity.

This asymmetry has turned rare earths into a geopolitical lever. China's refusal to fully reopen exports under the May 2025 Geneva truce—despite tariff reductions—has intensified U.S. efforts to diversify supply chains. The CHIPS Act, which allocated $52 billion for domestic semiconductor production, and the Critical Minerals Act, targeting REE independence, are cornerstones of this strategy.

Key Investment Plays

1. Rare Earth Mining: MP Materials (NYSE: MP)

As the sole U.S. rare earth miner, MP Materials is a bellwether for domestic supply chain resilience. Its partnership with Toyota to supply neodymium and praseodymium for EV motors—secured through the CHIPS Act—has driven a 35–40% stock surge since 2023. With plans to expand refining capacity in Texas and California, MP is well-positioned to benefit from rising demand and geopolitical tensions.

Why invest? Its vertically integrated model, government grants, and long-term contracts offer insulation against supply shocks.

2. Semiconductor Foundries: Taiwan Semiconductor Manufacturing (NYSE: TSM)

TSMC dominates global foundry capacity at 54%, making it indispensable to both U.S. and Chinese tech ecosystems. Despite a 15% dip in shares in early 2025 due to trade uncertainty, TSMC's scale and innovation (e.g., 3nm chips) give it a moat. A resolution to the tariff truce could unlock a rebound, as its clients (including Apple and Qualcomm) seek stability.

Risks? Its Taiwan-based operations remain vulnerable to geopolitical crossfires, but its $7.1 billion Q2 2025 revenue underscores demand resilience.

3. EV & Defense Firms: NIO (NYSE: NIO) and Raytheon Technologies (NYSE: RTX)

• NIO secures lithium through a joint venture with SQM, mitigating supply risks. Its $1.6 billion battery recycling facility in China aligns with circular economy trends.
• Raytheon relies on neodymium for precision-guided munitions. Its diversification into space systems and cybersecurity provides defensive stability.

Both companies exemplify the vertical integration needed to thrive in a fragmented supply chain world.

The August Deadline: A Binary Event

The August 12, 2025 deadline could either:
- Resolve tensions: Tariff reductions extended, rare earth exports normalized, and semiconductor controls eased. This would boost REE miners and foundries.
- Escalate conflict: Tariffs revert to pre-truce levels (up to 125% for the U.S.), triggering shortages in semiconductors and EVs.

Investors must prepare for both scenarios. Historical backtests from 2020 to 2025 reveal that a strategy of buying these stocks 10 days before tariff deadlines and holding for 30 days delivered an average return of 26.38%, though with a maximum drawdown of -13.91%, highlighting both opportunity and risk.

Backtest the performance of MP Materials (MP), Taiwan Semiconductor Manufacturing (TSM), NIO (NIO), and Raytheon Technologies (RTX) when buying 10 days before U.S.-China trade tariff deadlines and holding for meiden for 30 days, from 2020 to 2025.

Risks and Mitigation

• Supply Chain Bottlenecks: The U.S. relies on Asia for 60% of chip chemicals (e.g., lithography resists).
• Legal Uncertainty: U.S. courts have ruled prior tariffs “unlawful,” creating volatility.
• Regulatory Delays: Permitting for mines and fabs could slow timelines.

Mitigation: Focus on firms with long-term contracts (e.g., MP's Toyota deal) or CHIPS Act grants (e.g., Texas Instruments and Micron).

Investment Strategy

1. Buy MP Materials for its strategic role in REE production.
2. Hold TSMC for its dominance, but pair with stop-loss orders.
3. Diversify into EV/defense plays like NIO and Raytheon for hedged exposure.
4. Avoid Chinese semiconductor firms (e.g., SMIC) until trade clarity emerges.

The window to position ahead of August's deadline is narrowing. Companies with geopolitical hedging and operational agility will outperform in this volatile landscape.
