FXPARTNER Market Summary | 14.09.2026 Monday Midday Update

On Monday around midday, global markets focused on the sharp sell-off in technology and chip stocks after **Anthropic** CEO **Dario Amodei**, **OpenAI** CEO **Sam Altman** and **Elon Musk** each independently called, within **72 hours** of one another, for slowing the pace of AI development, along with oil's continued rise on a Saudi-driven pipeline shutdown and **Borsa Istanbul**'s lower start to the week. Following the slowdown call led by **Amodei**, who cited possible misuse risks, AI-linked stocks fell sharply in Monday's Asian session: **OpenAI** investor **SoftBank** slid by as much as **13.2%** in Japan, while chipmaker **Kioxia** lost **9.8%**, **Tokyo Electron** **3.7%**, **Taiwan Semiconductor (TSMC)** **1.2%**, and in South Korea **SK Hynix** **5.3%** and **Samsung Electronics** **3.7%**; the **MSCI Asia Pacific** index fell **0.5%**. The sell-off spilled over into US futures markets: **Nasdaq 100** futures dropped more than **1%**, **S&P 500** futures fell **0.6%**, and **Dow Jones** futures slid roughly **53 points (0.24%)**. On the energy side, according to **Bloomberg** the deepening shutdown of the **East-West Petroleum Pipeline** — halted by **Saudi Arabia** after attacks and used throughout the war to bypass the **Strait of Hormuz** — kept supporting oil prices; **Brent** crude, up about **9%** last week, moved toward **$108**, while **WTI** traded around **$103**. On the Turkish side, **Borsa Istanbul** opened the week down **0.88%** at **14,339.28** points amid weaker global risk appetite and geopolitical tensions; the banking index lost **1.07%** and the holding index **0.68%**; the index had closed Friday up **0.51%** at **14,467.25** points.
