Asian equity markets extended their decline on Tuesday, with the semiconductor sector bearing the brunt of the selling pressure.

The rout followed a losing session on Wall Street, where tech-heavy indices struggled to find support, and spilled over into Tokyo and other regional hubs.

Japanese semiconductor equipment manufacturers, including Tokyo Electron and Advantest, saw shares slide sharply, mirroring the weakness in US analog giants like Texas Instruments.

The broad-based drop underscores a severe repricing across the chip industry that has swept through both American and Asian markets.

Investor caution is mounting ahead of critical earnings reports from major US technology companies.

Market participants are also closely watching for the Federal Reserve's upcoming policy decision, which could further influence risk sentiment in an already volatile environment.
