Jones Industrial Average rose by 165.21 points, or 0.36%, closing at 46,669.88 points; the Nasdaq Composite Index increased by 0.54% to reach 21,996.34 points; the S&P 500 gained 0.44% and stands at 6,611.83 points. Meanwhile, the S&P and Nasdaq finished their fourth consecutive trading session gains, demonstrating market resilience amid uncertainty.

However, calmness in the market was disrupted by harsh rhetoric from the White House. U.S. President Trump held a press conference and issued an ultimatum to Iran — if demands are not met by 20:00 Eastern Time on April 7, the U.S. will deliver a devastating strike on Iran’s civilian infrastructure. He stated that a plan has already been developed capable of completely destroying all bridges and power plants in Iran within just four hours. This extreme statement caused a sharp decline in the three main indices, and market sentiment became more cautious.

In response, Iran sent the U.S. a 10-point proposal through Pakistan, with main demands including a final end to the conflict, an agreement on safe passage through the Strait of Hormuz, post-war reconstruction, and sanctions relief. Iran ruled out the possibility of a temporary ceasefire. Trump described the initiative as “significant but not good enough.” This struggle for control over the Strait of Hormuz has become a “Sword of Damocles” for the global economy.

Geopolitical risks directly impacted the markets. International oil prices surged: May WTI futures on the New York Mercantile Exchange rose by 0.78% — $112.41 per barrel; June Brent contracts increased by 0.90% — $110.05 per barrel. The market fears that a prolonged blockade of the strait could seriously disrupt global energy supply chains. Wells Fargo Bank Investment Institute warns that the risk of conflict escalation remains high in the coming weeks, and rising oil prices increase transportation and fertilizer costs, complicating the situation for economies dependent on energy imports. JPMorgan CEO Jamie Dimon also noted that supply disruptions could lead to inflation and higher-than-expected interest rates.
