Key Questions Answered

South Korean chip stocks extended their selloff due to escalating concerns over rising Chinese competition and worries that the artificial intelligence stock rally is becoming stretched. Specifically, investors reacted to reports of progress by China's CXMT Corp. on new memory architectures.

Progress by Chinese rivals, such as CXMT Corp. developing a new memory architecture that Samsung Electronics and SK Hynix are also working on, intensified market jitters and weighed on valuations. These competitive threats from China have increased concerns over the sustainability of the memory-chip market upcycle.

South Korean bonds have remained under pressure due to the Middle East war fueling inflation concerns via higher oil prices, as well as surging Treasury yields driven by traders betting on further Federal Reserve rate hikes. Meanwhile, Seoul has vowed to curb rising yields even as inflation stays above target.
