Asia-Pacific markets opened mixed to lower, with US sanctions on Iran and escalating US-Canada trade tensions weighing on regional sentiment. The KOSPI led losses with a decline of 4.30%, while Australia's ASX 200 bucked the trend.
Market performance across the region
The divergence across Asia-Pacific indices reflected uneven investor response to the dual headwinds. South Korea's KOSPI bore the sharpest impact, while Japan's Nikkei 225 also traded in negative territory. Australia's benchmark index managed a modest gain.
The table below summarises opening moves across key Asia-Pacific indices:
| Index | Change (%) |
|---|---|
| ASX 200 | +0.33% |
| Nikkei 225 | -1.35% |
| KOSPI | -4.30% |
Factors weighing on sentiment
Two developments shaped the cautious mood across markets. US sanctions on Iran introduced fresh uncertainty in energy and geopolitical risk calculations, while escalating trade tensions between the US and Canada added to concerns over North American trade flows and their broader economic implications for export-oriented Asian economies.
South Korea, with its heavy reliance on exports and global trade linkages, registered the steepest decline among the three indices. Japan's Nikkei 225 also retreated, reflecting sensitivity to global trade disruptions. Australia's ASX 200 managed to hold in positive territory, posting a gain of 0.33%, diverging from the broader regional trend.
How might the escalation of US-Canada trade tensions spill over to impact export-oriented economies in Southeast Asia?
What specific sectors within the KOSPI are most vulnerable to the combined effects of US sanctions on Iran and broader trade uncertainties?
Could Australia's relative market resilience signal a decoupling from Asian trade risks, or is it driven by commodity-specific factors?
