Asian markets tumble as US inflation data dashes rate-cut expectations

Asian markets entered a downward spiral as investors reassessed monetary policy outlooks following disappointing inflation figures from the United States. South Korea's benchmark Kospi index sustained the heaviest losses, plunging 5.6 percent, while Japan's Nikkei 225 declined 1.3 percent in afternoon trading. The broader sell-off reflected growing anxiety that persistent inflationary pressures could keep central banks on hold longer than previously anticipated, delaying relief for equity investors who have priced in rate reductions.

Technology and semiconductor stocks emerged as particular casualties amid the turbulent session. Companies with significant exposure to artificial intelligence development and deployment faced heightened selling, as investor appetite for high-growth equities waned under the shadow of a tighter monetary environment. The sector's sensitivity to interest rate expectations amplified daily losses across major bourses.

The sharp reversal in market sentiment underscored the delicate balance markets have maintained around rate expectations. While investors have increasingly banked on central banks pivoting toward cuts later this year, evidence of sticky inflation threatens to extend the period of restrictive policy, pressuring valuations across growth-oriented segments.
