SK Hynix surges 13% as AI memory supply fears dominate chip rally
Asian semiconductor stocks rallied sharply after cooler US inflation data eased macro concerns, while analysts doubled down on a looming AI memory supply deficit.
SK Hynix climbed 13% on Tuesday, leading a broad rally in Asian semiconductor stocks that saw Samsung Electronics gain nearly 8% and chip equipment maker Hanmi Semiconductor jump about 25% in early trade.
The immediate catalyst was a strong overnight session on Wall Street, where the S&P 500 and Nasdaq closed higher following cooler-than-expected United States inflation data and solid earnings from major banks. This macro relief offset lingering geopolitical tensions in the Middle East.
For chip investors, the surge marks a decisive shift from weeks of sector volatility. Markets had previously fretted that memory earnings growth would stall as price increases moderate in the second half of 2026. Concerns also centered on softer capital spending by major US cloud providers and the risk that aggressive capacity expansion by memory manufacturers would eventually resolve the industry's supply deficit.
Analysts, however, are increasingly dismissing those structural fears. Meritz Securities estimates that DRAM suppliers are currently meeting only 75% to 80% of demand, a shortfall that intensified in the second half of 2026. The brokerage forecasts that fulfillment rates will deteriorate further in 2027, stressing that supply will remain well below demand even after stripping out speculative orders.
The demand side is also viewed as locked in. HSBC expects improving profitability in AI services to sustain robust cloud spending. Furthermore, the industry's transition toward three- to five-year supply agreements is expected to provide chipmakers with greater earnings visibility and insulate them from recent volatility.
That structural tightness was underscored last week by SK Hynix Chief Executive Kwak Noh-jung. He warned that the global memory industry will face its worst-ever supply shortage in 2027, adding that demand is likely to outstrip the company's production capacity well beyond 2030, regardless of aggressive expansion plans.
For markets, the pricing action confirms that while short-term macro swings and financing costs will continue to cause ripples, the fundamental math of AI memory supply points to a prolonged period of strain. This dynamic effectively resets the valuation baseline for leading memory makers.
