South Korean Shares Extend Rally on US-Iran Deal

2026-06-15 01:35 By Erika Ordonez 1 min. read

The benchmark KOSPI climbed more than 5% to around 8,540 on Monday, extending gains for a third straight session as a US-Iran peace agreement boosted risk appetite.

Washington and Tehran reached a deal to end their monthslong conflict and reopen the Strait of Hormuz, with a formal signing ceremony expected later this week, easing concerns over global energy supplies and sending oil prices sharply lower.

The rally was broad-based, with technology and cyclical stocks leading gains as investors returned to risk assets.

Samsung Electronics (5.2%) and SK Hynix (7.4%) led the advance, along with Hyundai Motor (7.1%), LG Energy Solution (4.1%), HD Hyundai Heavy Industries (7.4%), Doosan Enerbility (7.3%), and KB Financial Group (7.3%).

Additional support came from strong domestic fundamentals, with South Korea's ICT exports reaching a record high in May, driven by surging semiconductor shipments and sustained AI-related demand.

South Korean Shares Surge on Iran Deal Hopes
The benchmark KOSPI climbed 4.63% to close at 8,124 on Friday, extending gains from the previous session as hopes for a US-Iran peace agreement sparked a broad risk-on rally across global markets. President Trump said the US was nearing a deal with Iran and had called off planned military strikes, raising expectations of easing tensions in the Middle East. Falling oil prices further boosted sentiment as reduced supply concerns helped curb inflation risks. Additional support came from strong gains in semiconductor stocks, with Samsung Electronics surging 7.86% and SK Hynix advancing 4.05% as investors returned to AI-linked chipmakers following a rebound in US technology shares. Other notable gainers included SK Square (11.64%), Hyundai Motor (2.43%), LG Energy Solution (3.38%), Kia Corporation (5.83%), Doosan Enerbility (4.06%), and Hanwha Aerospace (7.50%).

South Korean Shares Close Higher
The benchmark KOSPI rose 0.43% to close at 7,764 on Thursday, reversing earlier losses as investors turned optimistic on the outlook for the country's semiconductor sector. SK Hynix (2.64%) led the gains, alongside SK Square (3.80%), LG Energy Solution (1.04%), and HD Hyundai Heavy Industries (1.56%). Sentiment drew strength from South Korea's robust exports, which surged 86% year-on-year in the first 10 days of June to a record high, with semiconductor shipments more than tripling from a year earlier. Risk appetite was further supported by softer-than-expected US consumer inflation data, easing concerns over a more aggressive Federal Reserve policy stance. However, gains were capped by lingering geopolitical uncertainty after the US launched additional strikes against Iran, raising concerns over potential disruptions to shipping through the Strait of Hormuz and pushing oil prices higher.
