Asian stock markets opened Tuesday morning with mixed momentum as investors balanced optimism in China and India against weakness in Japan and South Korea. Currency fluctuations also played a key role, with the yen strengthening and the Australian dollar under pressure.

Asia Market Performance at the Open

Asian indices delivered a varied performance this morning, reflecting both regional resilience and global uncertainty.

• Shanghai Composite (000001.SS) rose +1.04% to 3,766.21, leading the region as Chinese equities gained on improved investor sentiment.
• S&P BSE Sensex (India) climbed +0.26% to 81,857.84, extending gains as domestic consumption and corporate earnings remain strong.
• S&P/ASX 200 (Australia) advanced +0.25% to 8,918.00, supported by strength in energy and mining sectors.
• Hang Seng Index (Hong Kong) edged up +0.17% to 25,165.94, as technology stocks stabilized after recent volatility.
• KOSPI Composite (South Korea) fell -0.68% to 3,130.09, dragged lower by weakness in semiconductor shares.
• Nikkei 225 (Japan) posted the steepest decline, dropping -1.51% to 42,888.55, as a stronger yen weighed heavily on exporters.

Currency Market Impact

Currency movements shaped early trading dynamics across Asia:

• Japanese Yen Index strengthened +0.20% to 67.87, making Japanese exports less competitive and pressuring the Nikkei.
• Australian Dollar Index weakened -0.39% to 64.32, reflecting softer demand in global commodities and cautious investor sentiment.

The yen’s rise highlights ongoing safe-haven flows, while the Australian dollar’s decline suggests investors remain wary of global growth prospects.

Key Market Drivers

Several factors are influencing Tuesday’s market action:

• China’s rebound: A modest recovery in domestic equities is helping the Shanghai Composite lead the region.
• India’s resilience: Continued economic growth and optimism in earnings reports are keeping the Sensex elevated.
• Tech sector caution: South Korea’s KOSPI reflects weakness in chipmakers, echoing global uncertainty in semiconductor demand.
• Currency pressure on Japan: A stronger yen is a persistent challenge for Japan’s exporters, amplifying today’s Nikkei decline.

Investor Sentiment

Market sentiment remains cautious as investors navigate the balance between regional growth stories and global headwinds. While China and India continue to provide resilience, Japan and South Korea highlight vulnerabilities tied to currency strength and technology demand.

Investors are closely monitoring:

• Corporate earnings guidance from Asia’s major exporters.
• Policy signals from central banks, particularly regarding interest rates and currency management.
• Global commodity trends, which directly influence the Australian and Indian markets.

Outlook for the Day

As Tuesday trading continues, analysts expect:

• Chinese and Indian equities to hold firm if domestic momentum persists.
• Japanese equities to face further pressure unless the yen stabilizes.
• South Korea’s KOSPI to remain sensitive to semiconductor market developments.
• Australia’s ASX to track energy and mining performance, with the weaker Australian dollar providing some relief to exporters.

Conclusion

Asian markets opened mixed on Tuesday, August 21, 2025, with strong performances in China and India offset by notable weakness in Japan and South Korea. Currency fluctuations remain a key theme, as the yen strengthens and the Australian dollar softens.

The day ahead will likely continue to reflect these crosscurrents, with investors weighing local growth resilience against global challenges in technology and trade.
