Affected Assets

The S&P 500 gained 2.3% and the Dow Jones surged over 800 points on March 31, 2026, following reports of a potential diplomatic breakthrough in the month-long U.S.-Iran war.
President Masoud Pezeshkian stated during a cabinet meeting that Iran is ready to end hostilities provided that the dignity, security, and interests of the nation are guaranteed.
Markets reacted to a leaked 15-point peace proposal that suggests a diplomatic off-ramp, leading to a risk-on boost for tech giants like Apple and Nvidia.
The rally follows a period of extreme volatility where the S&P 500 had dropped 6% year-to-date due to energy supply anxieties and the escalation of Operation Epic Fury.
Analysts from JPMorgan and BNP Paribas noted that while markets remain cautious, the prospect of a ceasefire could trigger a significant short squeeze and re-risking across global indices.
