Intel Corp. shares plunged in premarket trading after Chief Executive Officer Lip-Bu Tan delivered a lackluster forecast and cited persistent manufacturing problems. The chipmaker's struggles signal deeper challenges in the competitive semiconductor sector, where advanced node production remains a critical bottleneck for industry leaders.

Separately, the Bank of Japan held its overnight call rate at 0.75%, maintaining its hawkish stance. The decision spurred yen volatility, with the currency weakening against the dollar. Japan's top currency official later declined to comment on potential market intervention after the yen plunged over 150 pips in minutes.

Intel's outlook raises questions about its ability to compete with rivals like TSMC and Samsung in advanced chip manufacturing. Meanwhile, the BOJ's steady policy suggests a cautious approach to inflation, leaving the yen vulnerable to further swings amid global monetary shifts.
