South Korea's Kospi Surges to Record 8,094.90 on US-Iran Peace Talk Optimism

South Korea's Kospi index hit an all-time intraday high of 8,094.90 on Tuesday as investor sentiment improved on signs of progress in US-Iran peace negotiations. The benchmark index advanced 2.44% to 8,039.25 in early trade, while the small-cap Kosdaq gained 2.12%, reflecting broad-based risk appetite across Korean equities. The rally came after US President Donald Trump said negotiations were "proceeding nicely" with Iran, though he cautioned that the US could restart attacks if the talks failed.

The surge in Korean markets contrasts with mixed performance elsewhere in Asia, where Japan's Nikkei 225 fell 0.32% to 64,948.49 in early trading. The divergence suggests investors are pricing in Korea-specific tailwinds beyond the geopolitical de-escalation, potentially including expectations for improved export conditions and reduced supply chain disruptions if Middle East tensions continue to ease. The Kospi's breakthrough above its previous record marks a significant psychological milestone for a market that has historically traded at a discount to regional peers.

For investors, the key question is whether this rally has legs beyond the initial relief bounce. Trump's warning that attacks could resume if talks fail introduces meaningful tail risk, and any breakdown in negotiations could trigger sharp reversals in risk assets. The outperformance of the Kosdaq relative to the main board suggests retail and momentum traders are driving some of the gains, which could amplify volatility in either direction. Watch for confirmation from institutional flows and whether Korean exporters can sustain earnings momentum if geopolitical risk premiums compress further.
