Asia's AI hardware trade sold off sharply on Thursday as investors shifted attention from chip demand to the cost of financing the infrastructure boom. SK Hynix fell more than 10%, Samsung Electronics dropped 7.1% and SoftBank Group lost 7.9%, according to CNBC's market report.
The immediate pressure came after hotter U.S. inflation revived expectations of additional Federal Reserve tightening and pushed attention toward Treasury yields above 5%. Higher yields affect the sector in two ways. They raise the financing cost of data centers and other capital-heavy projects, and they reduce the present value investors assign to profits expected far in the future.
That does not by itself show that demand for high-bandwidth memory or AI accelerators has weakened. It changes the hurdle rate for projects and makes contract quality more important. Investors need to distinguish customers financing construction from customers paying from strong operating cash flow, and they need to watch whether planned capital spending is delayed, renegotiated or canceled.
SK Hynix is still investing for long-term demand. The company announced a 54 trillion won program covering 35.2 trillion won for its Yongin Cluster Y2 facility and 19.1 trillion won for the M17 fab in Cheongju. Cleanroom openings are planned for 2029 and 2028, respectively. Those dates show why financing conditions matter: today's investment supports capacity several years ahead, so utilization and pricing must remain strong long enough to earn an adequate return.
The selloff therefore reflects a valuation and funding concern more directly than a confirmed demand break. The bearish case would gain support from hyperscalers cutting capital budgets, weaker memory pricing or canceled infrastructure contracts. The constructive case requires those demand indicators to remain firm while balance sheets absorb higher rates. Until that evidence arrives, the market is repricing the cost of the AI buildout, not proving that the buildout has ended.
