Trump speaks out, combined with Iran calling for more, and the S&P 500 surged by $90 billion overnight

Gate News update: At the end of March 2026, a market move driven by both geopolitics and social media played out on U.S. stocks. Iranian parliament speaker Mohammad Bagher Ghalibaf publicly urged investors to “buy the dip” over the weekend. Hours later, Trump posted remarks on Truth Social about U.S.-Iran negotiations, directly flipping market sentiment, with the S&P 500’s market value recovering by roughly $90 billion in a short time.

The timeline shows that on Sunday evening in Eastern Time, S&P 500 futures briefly fell by nearly 1%, approaching a technical pullback range. However, by 11:00 p.m. that night, futures had fully recovered the losses and turned positive. The key turning point came on Monday morning: Trump said the U.S. is negotiating with a “more rational” new Iranian administration, while warning that if talks fail, it would hit its energy and water infrastructure. After the news broke, the index quickly surged by about 100 points, and risk-asset sentiment clearly improved.

This volatility is being viewed by the market as a typical “news-driven rally.” Research firm Kobeissi Letter noted that the market is currently in an extremely sensitive phase, in which political statements and signals from public opinion significantly amplify their impact on prices. Although equities rebounded in the short term, the crude oil market still maintained elevated range-bound trading; oil prices have continued to stay above $100 per barrel, reflecting that shipping risks through the Strait of Hormuz and tensions in the Middle East have not been resolved.

It’s also worth noting that, as of now, no formal diplomatic agreement has been finalized. The market’s rise relies more on expectation repair than on improvements in fundamentals. Ghalibaf’s remarks have also been interpreted by some as an indirect response to the phenomenon of how U.S. public-opinion efforts influence financial markets.

Against this backdrop, global investors are re-evaluating the pathways through which geopolitics affects asset pricing. If subsequent negotiations make substantive progress, equities may maintain a repair pace; conversely, if tensions escalate into conflict, volatility could quickly return and spread to risk assets, including Bitcoin.
