## Overview
US tech stocks fell after major AI groups called for a slowdown in the pace of AI development, with memory-chip makers and Nvidia sliding on Wall Street (FT, September 14). The selloff combined with a backdrop of rising oil prices, driven by the Saudi Arabia pipeline attack and Hormuz tensions, and higher borrowing costs from surging Treasury yields (FT, September 14).
## Key Developments

- The 10-year US Treasury yield hitting 5% for the first time since 2023 added to the pressure on high-valuation tech stocks (FT, September 14).
## Significance
