South Korea's Kospi index closed at a fresh all-time high on Monday, breaking through the 9,100 level for the first time.
The benchmark's ascent was broad-based but anchored by a continued surge in semiconductor shares, which have been the primary engine of the rally.
The move reflects renewed investor confidence in the sector, supported by broader optimism surrounding diplomatic developments between the US and Iran.
The breakout above 9,100 marks a significant psychological milestone for the Korean market, which has been buoyed by strong performance in its technology-heavy index.
Semiconductor stocks, a critical component of the Kospi, led the charge, benefiting from the improved risk sentiment.
The rally was not limited to chips, with gains spreading across other sectors as investors responded to the de-escalation of tensions in the Middle East.
