April 8, 2026: Lack of Iran Plan Creates Volatility

Markets endured another turbulent period, dominated by the ongoing U.S.-Iran conflict now in its sixth week. U.S. equities rode a volatile week higher and snapped a five-week losing streak—its longest since early 2022—while the Nasdaq experienced more volatility yet higher gains. Technology, communication services, and consumer staples led with gains while energy experienced profit-taking.

The S&P 500 rose roughly 3.4% for the holiday-shortened week, while the Nasdaq climbed approximately 4.4%. U.S. crude oil settled above $110/barrel for the first time since Russia’s invasion of Ukraine in 2022, stoking fresh inflation fears.

A spark on March 31 offered relief: stocks surged on unconfirmed reports that Iranian President Pezeshkian was open to ending the war, with the Dow jumping over 1,100 points and the S&P 500 gaining 2.9%—each index’s best day since May 2025. The bounce proved short-lived, however. Markets slipped in volatile trading on April 2 as oil prices surged following President Trump’s remarks that the Iran war would continue and set an April 6 diplomatic deadline for Iran, making that date a consequential near-term variable in the global macro outlook.

Overall, the persistence of geopolitical risk and elevated energy prices argues for continued market volatility. For investors, maintaining disciplined risk management and diversification may be prudent until greater clarity around an Iran exit plan emerges.
