Asian stock markets rise after the United States and Iran sign an initial agreement that ends the war, helping investors look past earlier weakness on Wall Street. Multiple outlets report that benchmarks in Japan and South Korea reach fresh highs on Thursday, with both indexes setting new records. The gains are described as broad across major Asian markets, with investors responding positively to the prospect of de-escalation following the agreement. One report notes that Asia “shrugs off” Wall Street worries, including a period of U.S. retreat, suggesting the deal is the dominant driver of sentiment in the region. While details beyond the signing of the initial agreement are not specified in the excerpts provided, all sources agree on the timing and direction of the market move: shares climb in Asia immediately following the U.S.-Iran signing. The story focuses on the market reaction rather than specific economic or policy implications of the deal.
