Asian stocks surged Monday, with Japan and South Korea leading gains, as a long-awaited US-Iran peace deal sparked a global 'risk on' rally. Crude oil plummeted 5%, according to Seeking Alpha, as traders priced in the removal of geopolitical risk premiums that had inflated energy prices for months.

Investor euphoria was further fueled by Friday’s record-breaking SpaceX IPO, which helped propel Japanese and Korean markets higher, the Financial Times reported. The combination of a major diplomatic breakthrough and a blockbuster tech listing triggered broad buying across equities, particularly in export-oriented Asian economies sensitive to trade and security disruptions.

The rout in oil dragged energy sector stocks lower globally, while airline and industrial shares climbed on expectations of lower fuel costs and reduced instability in the Middle East. Benchmark indices in Tokyo, Seoul, and Sydney all posted substantial gains, mirroring positive futures for U.S. markets.

Analysts caution that the peace deal's implementation remains untested, and any breakdown in negotiations could reverse today's sharp moves. The rally also raises questions about whether the market has fully priced in the long-term economic implications of a post-sanctions Iran re-entering global energy markets.
