Asian equity markets came under significant pressure as geopolitical escalation and losses in US technology stocks combined to dampen investor sentiment across the region. The selloff was broad-based, with major benchmark indices recording steep declines at the open.

Sharp Declines Across Key Asian Benchmarks

The regional market downturn was reflected prominently in the performance of leading indices. Japan's Nikkei 225 and South Korea's KOSPI were among the hardest hit, posting notable losses as risk-off sentiment took hold.

The KOSPI's decline of 8.37% was particularly sharp, underscoring the depth of negative sentiment in South Korean markets. Japan's Nikkei 225 also saw a significant drop of 3.65%, reflecting widespread caution among investors in the region.

Dual Pressures: Geopolitical Tensions and US Tech Weakness

Two primary factors drove the weakness across Asian equities. Geopolitical escalation contributed to a risk-averse environment, prompting investors to reduce exposure to equities across the region. Simultaneously, losses in US technology stocks added to the negative momentum, given the significant influence of the US tech sector on global market sentiment and its particular relevance to technology-heavy Asian indices such as the Nikkei 225 and KOSPI.

The confluence of these two headwinds created a challenging backdrop for Asian markets, with selling pressure evident across multiple sectors and geographies in the region.

Market Sentiment Overview

The weak start for Asian equities highlighted the sensitivity of regional markets to both global macroeconomic developments and geopolitical risks. The scale of the declines, particularly in South Korea, pointed to a pronounced shift in investor risk appetite. Markets across Asia reflected the broader global unease stemming from the combination of external geopolitical pressures and weakness in a key global sector.

Asia-Pacific equities started the session on a firmer footing after the S&P 500 and Nasdaq Composite hit new all-time highs, supported by gains in technology shares. The positive momentum from Wall Street provided a constructive backdrop for regional markets, driving broad-based advances across key Asia-Pacific benchmarks.

Regional Market Performance

The session reflected a broadly positive picture across Asia-Pacific indices, with South Korea's market emerging as the standout performer. The table below summarises the latest performance of key regional benchmarks:

Australia's ASX 200 edged down 0.13%, while Japan's Nikkei 225 advanced 1.72%, reflecting the positive spillover from Wall Street's technology-led rally. South Korea's KOSPI surged 3.94%, standing out as the strongest performer in the region during the session.

Key Factors Shaping Sentiment

The firmer trading environment across Asia-Pacific markets was shaped by a combination of developments that buoyed investor confidence:

• S&P 500 and Nasdaq Composite hitting new all-time highs provided a strong positive signal for regional markets, reinforcing risk appetite
• Gains in technology shares on Wall Street served as the primary catalyst, lifting sentiment across tech-heavy indices in the Asia-Pacific region
• Geopolitical crosscurrents, including ongoing US-Iran diplomatic negotiations and reports of American 'self-defence' strikes in southern Iran, continued to form part of the broader backdrop monitored by investors

Wall Street Momentum Drives Regional Gains

The session underscored the Asia-Pacific region's sensitivity to cues from US equity markets, particularly when major indices achieve significant milestones. The record-setting performance of the S&P 500 and Nasdaq Composite, driven by technology sector strength, translated into broad gains across regional benchmarks. While the ASX 200 posted a marginal decline, the advances in the Nikkei 225 and the sharp rally in the KOSPI reflected the positive tone set by overnight US market performance. Wall Street's technology-led momentum, rather than domestic economic data or geopolitical developments, served as the primary market catalyst across the Asia-Pacific region in this session.
