China's Q1 2026 GDP came in at 5.0% YoY, beating Bloomberg consensus of 4.7%. But Hang Seng fell -0.5% and Shanghai Composite -0.3% on the same day — because the market read the composition, not just the number.
Growth breakdown:
- Exports: +15% YoY (growth driver)
- Retail sales: +2.4% (weak recovery)
- Property investment: -11.2% (still contracting)
Korea sector impact:
- Semiconductors (+): Korea Q1 chip exports hit $30B for the first time (+139% YoY). This is AI capex-driven, NOT China GDP-driven. Decoupled cycle.
- Battery materials (mixed): CATL-supply chain firms benefit from Chinese EV production uptick. But cathode material makers face intensified Chinese competition.
- Cosmetics (limited): Korea-to-China cosmetics exports fell -9.6% despite +2.4% retail growth. Market share erosion is structural.
- Steel (limited): Property investment -11.2% caps construction steel demand recovery.
Key risk: US-China tariff war (effective rate ~31.6%, with 50% threat). May summit outcome is the single biggest variable for broad-based Korea export stock rerating.
