The benchmark Kospi index opened 0.26% higher on Tuesday, extending a positive momentum shift across Asian markets.
The modest advance was driven by a combination of overnight gains in US equities and a noticeable cooling of geopolitical risks in the Middle East.
The market's reaction reflects a dual catalyst: external sentiment from Wall Street's recent performance and an internal de-escalation of regional risk premiums.
Investors appear to be rewarding the reduced uncertainty surrounding Middle East tensions, which had previously weighed on global risk appetite and energy-linked volatility.
This opening marks a continuation of the positive momentum that swept through Asian markets earlier in the session.
The Kospi's performance suggests that traders are increasingly focused on the easing geopolitical backdrop rather than lingering concerns about broader macroeconomic headwinds.
