GT Voice: Why resisting US pressure matters for South Korean chipmakers - Global Times

The existential threat to Korean chipmakers isn't tariffs—it's the structural trap where compliance becomes capitulation. The 1985 Plaza Accord playbook that systematically dismantled Japan's memory dominance is being replayed through friend-shoring mandates and CHIPS Act compliance clauses. Once Samsung and SK Hynix's HBM fabs are embedded within US export-control frameworks, their advanced-packaging IP iteration cycles get locked to American licensing timelines. The autonomous evolution window for CoWoS-class technology is closing. Compliance costs have escalated from legal overhead to a transfer of capacity-allocation sovereignty. Each additional review layer stretches yield-ramp cycles by a quarter, and TSMC is exploiting that vacuum to capture foundry share. More critically, CXMT's DDR5/HBM3 progress is predicated on Korea being compliance-locked—the faster Seoul capitulates, the faster the domestic Chinese memory stack matures. Over the next 18 months, two trajectories emerge: SK Hynix will accelerate Wuxi expansion as a hedge against US review risk; Samsung's 2nm node will face de-Americanized validation, with yield penalties hitting 2026 earnings directly. Trading cooperation for market access will reduce Korea's semiconductor sovereignty to a tier-one foundry within three years.
