Korea's KOSPI fell more than 8% on Thursday, enough to halt trading for 20 minutes, after US September CPI came in at 3.7%. The print landed on a chip sector already sliding, and the clearest sign of costlier financing sits in AI borrowers' bonds.

Kospi opened up 1.8% on Friday after a 7.57% plunge to 5,554.22 that Yonhap tied to AI-trade worries and US inflation. The chip names trailed the index while banks and defense led, so the early rebound does not show the AI worry has eased.

Samsung, SK Hynix and SoftBank lost 9.5%, 11% and 9.3% in Asia while the 30-year Treasury yield fell 9.1 basis points. The drop added only 2.6% to the present value of a 30-year dollar, so the cause looks like AI borrowing and late revenue, with inflation as an add-on.

Kospi's 7.6% drop sends investors toward Treasuries yielding 5.09%
Kospi fell 7.6% as an AI-stock selloff pushed investors into bonds, taking the 10-year Treasury yield down nine basis points to 5.09%. Bloomberg's own strategist calls the bond move tactical, so one session is thin evidence that funding for AI buildouts has tightened.
