## Summary

**Global markets** saw sharp declines in AI-linked shares on October 14–15, 2026, after US inflation hit **3.7%** in September—its highest in three years since a **4.2%** peak in May. The sell-off triggered circuit breakers in South Korea’s **Kospi 200**, which dropped **8.1%** to a six-month low, with semiconductor stocks like **SK Hynix** and **Samsung Electronics** plunging **11%** and **9.5%**, respectively. Japan’s **Nikkei 225** fell **4.9%**, dragged down by **Kioxia** (**11%**) and **SoftBank** (**10%**), a major investor in **OpenAI** (ChatGPT’s parent). Wall Street’s **Nasdaq Composite** and **S&P 500** also declined **1.9%** and **1.1%**, their worst performance since July, as traders anticipated further US Federal Reserve interest rate hikes.

Analysts at **Deutsche Bank**, including **Jim Reid**, warned of broader economic risks beyond energy costs, noting price increases across consumer goods. The **International Monetary Fund** earlier this week flagged potential global financial instability from an AI-driven market correction, with Asian markets—particularly **China’s CSI 300** (**2.4% drop**) and **Taiwan’s TSMC** (**2% decline**)—vulnerable. European indices like the **Stoxx 600** and **FTSE 100** also dipped slightly, signaling broader caution amid geopolitical tensions, including US-Iran conflicts.
