Asian markets opened the new trading week with a mixed but generally weaker performance on July 13, 2026. A sharp selloff in South Korea dominated regional trading, while Japan and mainland China also declined. Meanwhile, India and Hong Kong managed modest gains, helping cushion broader regional losses.

The session reflected renewed investor caution after recent market volatility, with technology-heavy sectors once again leading the downside.

South Korea Suffers Sharpest Decline

South Korea’s KOSPI Composite Index plunged 8.61% to 6,832.21, recording the largest decline among Asia’s major equity benchmarks.

The sharp drop erased a significant portion of the market’s gains accumulated earlier this year and pushed the index below the psychologically important 7,000 level. Heavy selling in semiconductor, artificial intelligence, and technology-related companies weighed heavily on the benchmark as investors accelerated profit-taking.

The magnitude of the decline highlights South Korea’s continued position as one of Asia’s most volatile equity markets.

Japan Extends Recent Weakness

Japan’s Nikkei 225 declined 1.12% to 67,786.86, extending its recent pullback after reaching record highs above 72,000 in June.

The retreat reflected continued profit-taking across export-oriented manufacturers and technology companies. Despite the recent correction, the Nikkei remains one of the strongest-performing major equity indices globally in 2026.

Investors continue to view Japanese equities favorably over the longer term, although short-term volatility has increased.

China Remains Under Pressure While Hong Kong Holds Steady

China’s SSE Composite Index fell 0.73% to 3,967.08, remaining below the key 4,000 level and extending recent weakness in mainland equities.

In contrast, Hong Kong’s Hang Seng Index edged up 0.06% to 24,188.92. Although the gain was modest, it marked another session of relative resilience compared with mainland China and several other regional markets.

The divergence suggests investors remain selective when allocating capital across Greater China.

India Outperforms as Australia Slips

India’s S&P BSE Sensex gained 0.10% to 77,649.01, remaining relatively stable despite broader regional weakness.

Australia’s S&P/ASX 200 declined 0.33% to 8,776.80, reflecting mild weakness in mining and commodity-related sectors.

The contrasting performances demonstrate the uneven nature of investor sentiment across Asia at the start of the week.

Currency Markets Show Limited Movement

Currency markets remained relatively stable despite the sharp moves in equities.

The Japanese Yen Index rose 0.39% to 61.83, suggesting modest demand for defensive assets.

The Australian Dollar Index also gained 0.20% to 69.53, indicating that foreign exchange markets experienced considerably less volatility than regional equity markets.

Outlook

Looking ahead, investors will closely monitor whether South Korea can stabilize after falling below the 7,000 level and whether Japan can defend support near 67,500.

China’s effort to reclaim the 4,000 threshold will remain another important indicator of regional sentiment, while India’s resilience and Hong Kong’s relative stability may provide support if broader market conditions improve.

For now, Asia begins the week with renewed caution, as heavy selling in South Korea overshadowed modest gains elsewhere and reinforced concerns about continued volatility across regional equity markets.
