On Friday, the White House threatened a 100% tariff on all Chinese imports, citing national-security and “unfair trade” concerns. The move followed Beijing’s tighter limits on rare earths*—metals critical for chips, EVs, and defense gear. Markets sold off on impact; over the weekend, Washington’s tone softened, but investors are now repricing supply-chain and earnings risk.
The why: Officials framed the step as leverage against resource controls, to counter industrial overcapacity* and protect strategic tech. The legal pathway likely runs through Section 301* (the tool used for prior China duties), though scope and timing details still matter for markets.
The near-term market read: A broad tariff raises import costs and complicates corporate planning. History says tariff pass-through* to consumer prices is uneven—but margins at import-heavy sectors are the first shock absorber. Tech hardware, retailers, and automakers with China exposure are most exposed; commodity producers and domestic industrial suppliers may see relative support. Asia’s Monday open showed the spillover: stocks fell and gold caught a bid as investors hedged.
The bigger picture: Retaliation risk is real (think agriculture, licenses, and components), and global policy is already more protective—see Europe’s fight over Chinese EVs. That raises the odds of fragmented supply chains and “make-it-here” capex. For portfolios, that argues for diversification, attention to revenue geography, and a little shock insurance.
