Global financial markets remain volatile, driven by shifting interest rate expectations, rising bond yields, and sector rebalancing. While chip stocks previously showed signs of recovery, a significant sell-off recently impacted the semiconductor industry. In South Korea, the Kospi index dropped by more than 6%, with Samsung Electronics and SK Hynix falling over 7%. This downward pressure has extended to other major memory-chip manufacturers, including TSMC and Micron, following selling pressure in Asian markets.

This volatility has prompted discussions regarding the sustainability of artificial intelligence investment, as some analysts suggest corporations may find it harder to justify high levels of AI spending amid increased budget scrutiny. While semiconductor companies like Intel and Qualcomm saw gains after reaching an agreement with Amazon to develop custom AI chips, the software sector has faced pressure following the launch of OpenAI’s GPT-6 Astra, which raised concerns regarding industry disruption.

Economic and geopolitical factors continue to dictate movement. Investors are monitoring rising U.S. Treasury yields and potential Federal Reserve interest rate hikes. Geopolitical tensions have also intensified energy market volatility; oil prices rose following a statement from President Donald Trump regarding the reinstatement of a blockade of Iranian ships in the Strait of Hormuz. This announcement has raised significant concerns regarding regional security and the potential for disrupted shipping through the critical maritime passage connecting the Persian Gulf to international markets.
