A broad-based selloff in global equity markets intensified on Tuesday, spreading from South Korean exchanges to emerging-market assets and technology-heavy indices.

The decline was driven by growing investor anxiety over potential valuation bubbles in the artificial intelligence sector, prompting a wave of risk-off trading across multiple asset classes.

The selling pressure, which began in Korea, quickly infected other markets, with Argentine bonds and equities among the hardest hit.

The rout followed a weak session on Wall Street, where tech stocks struggled to find support amid fears that AI-related valuations have become stretched.

The move reflects a broader shift in sentiment, with investors rotating away from high-growth tech names toward safer havens.

This latest downturn comes on the heels of a sharp selloff in global bond markets triggered by escalating conflict in the Gulf region.
