米イラン間の紛争終結の可能性に投資家の期待が高まり、金曜日のソウル株式市場は大幅に上昇した。ベンチマークとなるKOSPI指数は4%を超えて上昇し、再び8,000ポイントを上回って取引を終えた。
KOSPIは一時8,434.40まで上昇した後、前日比359.67ポイント（4.63%）高の8,123.62で取引を終えた。外国人投資家は25日間にわたる売り越しから買い越しに転じた。
ドナルド・トランプ米大統領は木曜日、イランとの数ヶ月にわたる紛争を解決するための「素晴らしい合意」に達したと述べ、週末にも欧州で合意文書に署名する可能性があるとした。
サムスン電子は7.86%高の32万2,500ウォンとなり、SKハイニックスも2.33%上昇した。対ドルでのウォン相場は9.1ウォン上昇し、1ドル＝1,519.8ウォンとなった。
X（旧Twitter）での初期の反応は、米イラン和平交渉への期待を背景としたKOSPIの4〜8%超の急騰に集中しており、報道機関による中立的な報告や、半導体関連株の上昇およびアジア市場全体への前向きな評価が見られる一方、合意の信頼性や市場のボラティリティに対する懐疑的な見方も一部で示されている。
