Asian markets opened the week on a weaker note on August 24, 2026, as selling pressure returned across several major equity markets. South Korea recorded the steepest decline, followed by Hong Kong and Japan, while mainland China and India also moved lower. Australia provided a notable exception, with both its equity benchmark and currency advancing.

The session reflected a renewed divergence across the region after the mostly positive performance recorded at the end of last week.

South Korea Leads Regional Declines

South Korea’s KOSPI Composite Index fell 3.12% to 6,696.96, recording the largest decline among Asia’s major equity benchmarks.

The retreat pushed the index back below the 7,000 level after it had approached that threshold during the previous week’s recovery. The decline highlights the continued volatility affecting Korean equities following the sharp swings experienced throughout August.

The KOSPI remains particularly sensitive to changes in investor appetite toward technology and semiconductor stocks.

Hong Kong Retreats From 26,000

Hong Kong’s Hang Seng Index declined 1.89% to 25,517.33, giving back a significant portion of its recent gains.

The benchmark had approached the 26,000 level last week, but Monday’s decline moved it further away from that threshold. The retreat indicates renewed caution toward Hong Kong-listed and China-linked equities following the market’s recent recovery.

Despite the decline, the Hang Seng remains above the important 25,000 level.

Japan and China Also Move Lower

Japan’s Nikkei 225 fell 0.74% to 65,528.09, continuing its recent consolidation after the benchmark experienced substantial volatility throughout August.

China’s SSE Composite Index declined 0.59% to 3,882.01, moving further away from the important 4,000 level.

The weakness in both markets contributed to the broader negative tone across Northeast Asia and mainland China.

Australia Provides a Regional Bright Spot

Australia’s S&P/ASX 200 gained 0.49% to 9,103.10, making it the strongest-performing major equity benchmark in the region during Monday’s session.

The index returned above the 9,100 level as investors maintained exposure to Australian equities despite weakness across most other Asian markets.

The Australian Dollar Index also strengthened significantly, rising 0.85% to 71.71, recording the strongest move among the reported regional currencies.

India Edges Lower

India’s S&P BSE Sensex declined 0.26% to 77,338.51, giving back a modest portion of its recent gains.

The relatively small decline compared with South Korea, Hong Kong, and Japan suggests that selling pressure remained more limited in the Indian market.

The Sensex continues to demonstrate greater stability than several of its regional counterparts during the current period of elevated volatility.

Currency Markets Remain Mixed

The Japanese Yen Index edged higher by 0.06% to 62.90, remaining broadly stable during the session.

The Australian Dollar Index, however, posted a much stronger gain of 0.85% to 71.71, moving higher alongside Australia’s equity market.

The divergence between the two currencies reflects the mixed nature of regional investor positioning at the beginning of the week.

Outlook

Looking ahead, investors will monitor whether South Korea can stabilize around the 6,700 level and whether Hong Kong can regain momentum toward 26,000.

China’s ability to recover toward the 4,000 threshold will remain an important indicator of regional sentiment, while Japan will be watched for signs of stabilization above 65,000.

Australia’s ability to maintain the S&P/ASX 200 above 9,100 and its currency above 71 will also be closely monitored as one of the region’s relative bright spots.

For now, Asia begins the week with a cautious tone, as sharp declines in South Korea and Hong Kong offset gains in Australia. The uneven performance highlights the continued volatility across the region and the selective approach investors are taking toward Asian equities.
