Summary

Shaun Rein argues China has the upper hand in the US-China trade war because of rare earth leverage and US dependence, while both economies are hurting. He thinks China's rare earth export controls were a strategic mistake that will accelerate ex-China refining, especially in Australia. He is bullish on Chinese semiconductors and China's economy, bearish on Nvidia's China business, and warns US equities could collapse if no trade deal is reached. He also discusses tariff-driven margin pressure, China's property and deflation problems, and declining Chinese student immigration to the US.

  • Shaun Rein says China has leverage in the trade war due to rare earth refining dominance and US reliance.
  • China's rare earth export controls may backfire by prompting Australia and others to build ex-China capacity.
  • Rein is bullish on Chinese semiconductor companies and China's economy, citing distrust of US tech and trade-war advantage.
  • Nvidia's China market share has fallen from 95% to 0%, a major loss for Nvidia and US tech exports.
  • A no-deal scenario with 100% tariffs could collapse US equities, while Trump is sensitive to market pressure.
  • US tariffs are squeezing retailer margins and risking stagflation; Amazon and Walmart may pass costs to consumers.
  • China faces deflation and weak property, with housing prices down 30-50% and consumers delaying big purchases.
  • Chinese student immigration to the US is likely to keep declining due to visa fears and poor ROI.
Ideas

BYD gains share with cheap EVs.
BYD has replaced BMW and Toyota as the largest car seller in Singapore, showing the competitiveness of Chinese NEVs. Rein also highlights BYD's $8,000 car with fully autonomous features, supporting its global market-share gains.

US equities collapse if no deal.
Rein warns that if no US-China accommodation is reached and Trump's 100% tariffs take effect on November 1, American equity markets will collapse, which Trump does not want. He expects a deal or rollover, but the no-deal scenario is a clear downside risk for US equities.

Nvidia losing China market share.
Rein says Nvidia is done in China: its China market share fell from 95% to 0% and it is losing about $17 billion a year. Export controls and broken agreements have destroyed Chinese trust in the US tech supply chain, so China is building indigenous semiconductors instead.

Tariffs squeeze Amazon and Walmart margins.
Tariffs are squeezing margins at US retailers like Amazon and Walmart. They initially absorbed costs and stockpiled, but that is unsustainable; over the next six months they may pass roughly $1 trillion in tariff costs to consumers. This is a negative margin and demand setup for these retailers.

Australia leads ex-China rare earth refining.
Rein argues China's rare earth export controls were a mistake that will backfire by rallying the world to build ex-China refining capacity. Australia is taking the lead in rare earth mining and refining outside China, Lynas has the best refining technology outside China, and the new US-Australia critical minerals deal supports the sector; he says investors should look there.

Buy Chinese semiconductors on US distrust.
Rein is super bullish on Chinese semiconductor companies because China no longer trusts the US technology supply chain and is building indigenous innovation. US export controls and weaponization of technology are pushing the global majority to buy Chinese tech, so companies like Cambricon and Hua Hong are powering China's and the global majority's AI boom.

China bullish on trade-war advantage.
Rein is more bullish on China's economy than at any time in the last six years because China is winning the trade war, animal spirits are returning, and Hong Kong equities are among the world's best performers in 2025. He still cautions China is not booming, with deflation, weak property, and weak income limiting consumption, but he sees China doing better than the US in the trade war.

Avoid China real estate on deflation.
Chinese housing prices have dropped 30-50% and deflation makes buyers expect cheaper prices next month, so they delay big-ticket purchases and keep money in time deposits. Weak real estate is a major drag on Chinese consumption and the broader economy.

Starbucks loses China to cheaper Luckin.
Starbucks is in trouble in China because value-seeking consumers can buy coffee from Luckin for 10 RMB versus 35 RMB at Starbucks. This price disadvantage is a structural headwind for Starbucks' China business.
