Asian equities tumbled on Thursday, October 15, as a bruising selloff in technology stocks crossed the Pacific from Wall Street and gathered speed in the region's chip-heavy markets. South Korea's Kospi index plunged as much as 6.5% intraday to its lowest level since late July before closing down 5.72%. Japan's Nikkei 225 fell 3.1%. The MSCI Asia Pacific equities gauge dropped 1.5%, putting it on course for a fourth straight decline.
The trigger was Wednesday's hotter-than-expected US inflation print. September CPI came in at 3.7% year-on-year and 0.6% month-on-month, the fastest monthly pace in five months, while core CPI ran at 2.6%. Traders responded by pricing roughly 40 basis points of additional Fed tightening by the end of January, and odds of an October 28 hike jumped to around 49%. The two-year Treasury yield spiked as much as 16 basis points intraday, and the five-year crossed 5.15% for the first time since 2007. Yesterday's Wall Street slide after the hot CPI release and the surge in October hike pricing showed how fast the rate path repriced.
Semiconductor names bore the brunt. SK Hynix plunged more than 10%, Samsung Electronics slid 7.1%, and losses spread across the supply chain: SoftBank Group fell 7.9%, Advantest dropped 6.9%, Tokyo Electron and Renesas Electronics each lost 5.4%, while LG Innotek, Seoul Semiconductor and Samsung SDI all declined between 6.8% and 8.1%.
Why it matters
This selloff has two engines, and both are running at once. The first is the rate repricing: 40 basis points of hikes by January equals more than one full additional quarter-point move on top of the September 25bp hike, and October is genuinely in play again. The second is a growing financing anxiety around the AI infrastructure boom itself. Broadcom CEO Hock Tan warned this week that securing funding could be a bigger constraint on AI expansion than chip or electricity shortages, and Intel's leadership flagged the same headwind on Monday. After a blistering rally in AI-linked shares, investors are asking whether the pace of capital spending can survive materially higher borrowing costs. The numbers show the rout is concentrated rather than broad: the average decline across the big chip names was roughly 7%, nearly five times the 1.5% drop in the MSCI Asia Pacific gauge. And the fear spread to credit, with CoreWeave's shares plunging 17% while its 2032 debt traded below 78 cents on the dollar after being bought at par just four months ago.
What to watch
- Fed Chair Kevin Warsh speaks at a late-Thursday fireside chat in Bangkok with IMF Managing Director Kristalina Georgieva, a forum that drew sharp scrutiny given the rate debate.
- The October 28 FOMC meeting: roughly even odds of another hike, with a December follow-through on the table according to strategists at Regan Capital.
- Nasdaq 100 futures fell as much as 1% as Asia traded, signaling the rout may spill back into tonight's Wall Street session.
- Hyperscaler capital spending plans and earnings from AI-infrastructure names — Yorkville Ives' Dan Ives says cuts in capex plans, canceled contracts, or falling GPU rental prices would be the real demand signals to worry about.
MarketRadar take
The rate story and the AI-financing story are now the same story. As Ives put it, this is a financing question rather than a demand question, which means every CPI print and every Warsh remark directly reprices chip multiples. With 40 basis points of hikes priced by January and the Kospi at multi-month lows, the near-term path of least resistance for Asian equities remains downward, especially in AI-exposed names. Watch whether the MSCI Asia Pacific gauge breaks its July low and whether tonight's Wall Street session absorbs or amplifies Thursday's Asia move.
