Nikkei Advances, Kospi Declines As Markets Gauge US-Iran Truce
Asian stocks mixed on US-Iran truce uncertainty, oil volatility weighs heavy.
Asian markets presented a mixed picture on April 9, 2026, as investors cautiously assessed the fragile US-Iran ceasefire and its implications for global energy flows through the Strait of Hormuz. Japan's Nikkei 225 index edged higher, gaining modest ground in early trading amid optimism over de-escalation, while South Korea's Kospi slipped lower, reflecting jitters over lingering supply disruptions. The divergence highlights regional sensitivities to oil volatility following the two-week truce announced after weeks of conflict.
The Nikkei climbed around 0.03% to near 55,997 in initial sessions, buoyed by exporter gains and a softer yen after the ceasefire eased fears of prolonged Middle East tensions. Technology and manufacturing heavyweights led advances, with analysts noting relief from Brent crude's rebound to $97 per barrel, which had plunged sharply post-truce before uncertainty returned via Iran's navigation controls. Tokyo's resilience stems from diversified supply chains less exposed to Gulf imports compared to neighbors.
In contrast, the Kospi dropped 1.28% to 5,797, weighed by semiconductor and auto sectors hit by Hormuz risks and shipping delays. Seoul's export-driven economy, reliant on Middle Eastern energy, amplified concerns over potential Iranian restrictions despite the pause in strikes. Recent volatility saw Kospi swing from 6.87% surges on ceasefire hopes to pullbacks as reality set in.
