Asian markets closed mixed on May 21, 2026, as a powerful rebound in South Korea and Japan offset continued weakness in China and Hong Kong. Investor sentiment improved significantly following recent selloffs, with capital returning aggressively to technology and growth-oriented equities.

The session reflected a sharp divergence between Northeast Asian markets and Greater China equities.

South Korea Leads Explosive Recovery

South Korea’s KOSPI Composite Index surged 8.42% to 7,815.59, delivering the strongest performance across Asia and recovering much of the sharp decline seen in previous sessions.

The rebound signals renewed investor confidence in Korean semiconductor and artificial intelligence-related companies, which had previously experienced aggressive profit-taking. The move also highlights the continued volatility surrounding one of Asia’s strongest-performing markets this year.

Japan’s Nikkei 225 rallied 3.14% to 61,684.14, climbing back above the 61,000 level and reinforcing bullish momentum in export-driven and technology sectors.

Australia’s S&P/ASX 200 also advanced strongly, gaining 1.47% to 8,621.70, supported by renewed buying in cyclical and commodity-linked shares.

China and Hong Kong Extend Weakness

Despite gains elsewhere, China and Hong Kong continued to struggle.

China’s SSE Composite Index fell 2.04% to 4,077.28, marking the steepest decline among major markets outside South Korea’s previous correction phase. The drop suggests ongoing investor caution toward mainland Chinese equities.

Hong Kong’s Hang Seng Index declined 1.03% to 25,385.69, extending recent weakness and reflecting continued pressure across regional Chinese-linked assets.

India’s S&P BSE Sensex edged slightly lower by 0.17% to 75,187.20, indicating relatively stable but cautious trading conditions.

Currency Markets Reflect Improving Risk Appetite

Currency markets showed signs of stabilization and moderate risk-on positioning.

The Australian Dollar Index rose 0.60% to 71.52, aligning with stronger Australian equities and improved investor sentiment.

Meanwhile, the Japanese Yen Index edged up 0.10% to 62.94, indicating balanced positioning between defensive and growth-oriented assets.

The stronger Australian dollar reinforces the view that investors cautiously returned to higher-risk assets during the session.

Israel Market Closed for Shavuot Eve

Regional participation was slightly reduced as Israel’s Tel Aviv Stock Exchange remained closed for Pentecost (Shavuot) Eve.

The closure had minimal impact on broader Asian trading activity.

Outlook

Looking ahead, investors will monitor whether South Korea can sustain momentum near the 7,800 level and whether Japan continues rebuilding strength above 61,000.

At the same time, continued weakness in China and Hong Kong remains a significant concern for broader regional stability. Diverging performance across Asia suggests markets are becoming increasingly selective, with investors favoring technology-driven growth economies over slower-moving mainland Chinese equities.

For now, Asia’s markets remain highly volatile but active, with strong rebounds emerging alongside persistent regional fragmentation.
