Asia-Pacific equity markets traded mostly higher, buoyed by positive momentum from Friday's session on Wall Street. The broad-based gains across the region were underpinned by weaker-than-expected U.S. jobs data, which led traders to scale back their expectations for further Federal Reserve rate hikes. The development provided a broadly supportive environment for regional risk assets.

Regional Market Performance

The session saw a divergence in performance across major Asia-Pacific indices. Japan and South Korea posted notable gains, while Australia's benchmark index edged lower. The following table summarizes the performance of key regional indices:

Market Drivers

The primary catalyst for the regional market moves was the release of weak U.S. jobs data, which influenced investor sentiment across Asia-Pacific trading sessions. The softer employment figures from the United States prompted market participants to reassess the likelihood of additional interest rate increases by the Federal Reserve. A more dovish rate outlook generally supports equity valuations by reducing the cost of capital and improving the relative attractiveness of risk assets.

Japan's Nikkei 225 emerged as the standout performer in the region, advancing 1.30%, while South Korea's KOSPI posted a solid gain of 1.06%. Australia's ASX 200 was the exception, slipping 0.19% against the otherwise positive regional trend.

Wall Street's Influence

Friday's gains on Wall Street set a constructive tone heading into the Asia-Pacific trading session. The positive close on U.S. markets, combined with the implications of the weaker jobs report, contributed to the broadly upbeat sentiment observed across most regional bourses. The interplay between U.S. economic data and global market expectations for Federal Reserve policy continued to serve as a key driver of cross-market sentiment.

Asia-Pacific equity markets opened on a weak note, tracking mixed signals from U.S. markets where the Nasdaq faced selling pressure. The catalyst behind the technology-sector weakness was attributed to reports of China successfully rolling out domestically developed Deep Ultraviolet (DUV) lithography equipment—a development with significant implications for the global semiconductor supply chain.

Regional Market Performance

The negative sentiment spread broadly across the Asia-Pacific region, with major indices recording declines at the open. The following table summarises the opening performance across key benchmarks:

Among the major indices, South Korea's KOSPI registered the steepest decline at -6.47%, reflecting the country's significant exposure to the semiconductor and technology hardware sectors. Japan's Nikkei 225 followed with a decline of -3.20%, while Australia's ASX 200 saw a comparatively modest dip of -0.32% at the open.

China's DUV Lithography Development as a Key Driver

The primary technology-related trigger for the regional selloff was the reported rollout of domestically developed DUV lithography equipment by China. DUV lithography is a critical technology used in semiconductor manufacturing, and China's reported progress in developing such equipment domestically carries broad implications for existing global suppliers and chipmakers across the Asia-Pacific region.

The news contributed to Nasdaq weakness in the preceding U.S. session, which in turn transmitted negative sentiment to Asian markets at the open. Countries with deep semiconductor industry ties—particularly South Korea and Japan—appeared most acutely affected by the development.

Broader Market Context

The declines across Asia-Pacific markets unfolded against a backdrop of mixed U.S. market cues, suggesting that while broader risk sentiment was not uniformly negative, technology-specific concerns dominated the open. The divergence in the scale of losses across indices—from the relatively contained ASX 200 decline to the sharp KOSPI drop—reflects the varying degrees of technology sector concentration within each market.

Key observations from the session opening include:

• KOSPI recorded the largest decline among the three indices, consistent with South Korea's prominent role in global semiconductor manufacturing.
• Nikkei 225 also saw a significant drop, reflecting Japan's exposure to technology hardware and equipment sectors.
• ASX 200 posted a more limited decline, in line with its relatively lower concentration of semiconductor-related equities.

The session underscored how developments in the global semiconductor landscape can rapidly transmit across Asia-Pacific financial markets, particularly when they intersect with existing geopolitical and trade dynamics.
