In a shift reflecting growing anxiety over the sustainability of the AI boom, technology sector declines spread from Asia to European and global markets on Monday, September 14. This expansion was driven by mounting fears regarding impacted corporate capital expenditure, coupled with additional pressure from rising oil prices, following calls from prominent AI lab leaders at Anthropic and OpenAI to slow the pace of frontier model development for safety reasons.

Per market data, chip-related stocks saw sharp losses as SoftBank Group plummeted 10.7%, SK Hynix dropped 6.4%, and Samsung Electronics lost 4.1% of its value. The sell-off extended to regional benchmarks with South Korea's Kospi falling 3.3% and Japan's Nikkei 225 declining 0.8%, signaling a broader re-evaluation of risk amid potential regulatory intervention or a slowdown in the technological progress currently baked into valuations.

Investors should watch key support levels for major tech stocks in upcoming sessions, with SoftBank Group closing at 10,250 JPY (close September 14, 2026). Market focus will remain on economic data that could alleviate inflationary pressures from oil prices, as well as any official regulatory responses to the global AI safety coordination proposals suggested by Dario Amodei.
