U.S. Market Rally Tied to Trump’s Decision to Hold Off on Iran Strikes
8/4/2026, 11:12:46 AM
Core Event
On August 3 2026, U.S. President Donald Trump announced the United States would refrain from new attacks on Iran, saying the move was intended to facilitate diplomatic talks. The announcement coincided with a drop in oil prices—Brent crude fell to a range of $83.4-$83.9 per barrel—and sparked a rally in U.S. equities. The S&P 500 rose 1.48% to 7,600.50, the Dow Jones Industrial Average climbed 1.32% to 53,178.41, and the Nasdaq Composite advanced 2.13% to 25,913.90. The Japanese yen strengthened near 156 per dollar, while the 10-year U.S. Treasury yield slipped to roughly 4.68%.
Background & Context
The oil price decline followed weeks of heightened tension after U.S. and Israeli strikes against Iran, which had constrained Gulf oil flows. Earlier in the month Brent had briefly topped $100 per barrel before retreating as the conflict intensified. Trump framed the pause as a “gesture of goodwill” aimed at reopening the Strait of Hormuz. Simultaneously, U.S. and Japanese authorities conducted coordinated yen-buying intervention to curb the yen’s slide to multi-decade lows.

Official Statements & Responses
- U.S. Treasury Secretary Scott Bessent indicated the United States would consider expanding the Federal Reserve’s repo facility as an “important backstop” for dollar liquidity.
- U.S. and Japanese officials described the coordinated move as a “sign of friendship” and a measure to support the global economy.
Conflicting Reports & Gaps
Sources report slightly different Brent prices at the time of the rally: Reuters cites $85.12, $83.88, and $83.77; AP notes $83.83; Barchart lists $83.64; and Ts2 records $83.52. The variance reflects timing differences across markets but all indicate a roughly 4–5% decline from the recent peak. No source provides a definitive forecast for the durability of the oil-price relief or the outcome of pending U.S.–Iran talks.
