Asian markets delivered a sharply divided performance on October 12, 2026, as Australian equities recovered while South Korean stocks came under heavy selling pressure. Three of the six reported equity benchmarks finished lower, with the KOSPI’s steep decline standing out against more modest movements across Japan, Hong Kong and mainland China. The session highlighted persistent differences in regional market momentum as investors assessed the latest trading levels.

Australia Leads Regional Gains

The S&P/ASX 200 advanced 0.76% to 8,783.20, making it the strongest-performing equity benchmark in the supplied data. The index moved closer to the 8,800 threshold, recovering after falling 0.77% to 8,660.90 on October 8.

The Australian Dollar Currency Index also strengthened, rising 0.39% to 69.86. Gains in both the equity benchmark and currency indicator pointed to a firmer session for Australian markets, although the sustainability of the recovery will depend on whether the ASX 200 can maintain its upward momentum.

South Korea Faces Renewed Selling Pressure

The KOSPI Composite Index plunged 3.65% to 6,384.24, extending its recent weakness and moving further below the 6,500 level. The decline was substantially larger than the losses recorded by other Asian equity benchmarks in the session.

The latest drop leaves South Korean equities under considerable pressure following the index’s earlier fall to 6,625.93 on October 8. The move below 6,400 places renewed attention on whether the benchmark can stabilize or whether selling pressure will continue into subsequent sessions.

India and China Remain Under Pressure

India’s S&P BSE SENSEX declined 0.76% to 71,924.68, moving back below the 72,000 threshold. The decline followed the index’s previous close at 71,593.24 on October 8, indicating that the recent recovery has remained uneven.

The SSE Composite Index fell 0.43% to 3,797.24, slipping below the psychologically important 3,800 level. The move reversed part of its earlier stability and placed the benchmark closer to a level that investors may monitor for potential support.

Hong Kong and Japan Show Relative Stability

The Hang Seng advanced 0.25% to 24,271.20, extending its recovery above 24,000 after falling to 23,785.79 on October 8. The modest gain suggested relative resilience compared with the sharper declines in South Korea and India.

The Nikkei 225 was nearly unchanged, slipping just 0.02% to 69,030.92. Japan’s Tokyo Stock Exchange was closed for Sports Day, according to the supplied market note, so the reported Nikkei figure should not be interpreted as evidence of active trading during the holiday.

The PHLX Yen declined 0.28% to 63.17, indicating modest currency weakness despite the limited movement in the reported Japanese equity benchmark.

Outlook

Asian markets enter the next trading session with diverging signals. Australia’s advance toward 8,800 offers a more constructive picture, while the KOSPI’s fall below 6,400 and the SSE Composite’s move under 3,800 highlight areas of weakness. The Hang Seng remains above 24,000, whereas the Sensex is hovering just below 72,000. Investors will be watching for stabilization in South Korea and mainland China, alongside evidence that Australia’s recovery can extend beyond a single session.
