Nikkei and Kospi record highs gave Asia the clearest equity win from the Iran-deal relief trade. Japan and South Korea rallied as lower oil risk met another wave of AI-chip optimism.
The move shows how quickly global investors are rotating toward markets that combine cheaper energy, strong tech exposure and momentum in semiconductor supply chains.
What happened
AP reported that Japan's Nikkei 225 gained 1.7% to a new peak of 71,053.49, while South Korea's Kospi rose 2.3%. The rally followed the initial U.S.-Iran agreement and was helped by AI-linked technology shares.
Barron's reported that Japan's Nikkei closed above 70,000 for the first time. Trading Economics also showed Japan and South Korea indexes at or near record levels on June 18.
Why Nikkei and Kospi records matter
Asia's record move matters because it shows the market is not treating the Fed shock as a global blanket sell signal. Investors are still rewarding countries and sectors with AI earnings leverage.
Market impact
Samsung and SK Hynix strength helped South Korea, while Japanese electronics names supported Tokyo. The weaker oil backdrop also helps energy-importing economies, especially if the Hormuz reopening holds.

Institution angle
