The "Confidence Booster" of Geopolitical Détente—Why Did U.S. Stock Futures Turn Up Overnight?

Trump's Withdrawal Signal Sparks Market Sentiment

On April 1, 2026, a major signal came from the Asia-Pacific early trading session: U.S. stock index futures collectively turned higher. As of 8 a.m. Beijing time, the S&P 500 futures rose 0.3%, Nasdaq 100 futures increased 0.5%, and Dow Jones futures moved up in tandem.

The immediate catalyst for this rally was a dramatic shift in the Middle East geopolitical situation. President Trump explicitly stated on March 31 that the U.S. would end military operations in Iran "within two to three weeks," and even if no agreement is reached, a withdrawal will be initiated. This statement completely reversed the market’s previous pessimistic expectations—investors had been concerned that prolonged conflict would push oil prices higher, increase inflation, and force the Federal Reserve to maintain tightening policies.

The U.S. stock market had already reacted overnight. On March 31, the Dow surged 1,125 points, a 2.49% increase; the Nasdaq soared 3.83%; and the S&P 500 jumped 2.91%, with all three indices posting their largest single-day gains since May 2025. Leading the rally were large tech stocks, with Nvidia up over 5%, Google up more than 5%, and Meta soaring 6.7%.

What is the market trading?

Bill Northey, Senior Investment Director at U.S. Bank Wealth Management, said, “What the capital markets are reflecting today is an expectation of an early turnaround in the situation. Although the details remain unclear, the market is looking for signals that energy transportation through the Strait of Hormuz will return to normal.”

Notably, the energy sector declined by 1.2% against the trend, indicating that funds are withdrawing from the “war premium.” The U.S. dollar index ended its five-day rally, falling back below the 100 mark; U.S. Treasury yields also retreated, and concerns about policy tightening have noticeably eased.

However, behind the optimism, there are still concerns. Trump is accustomed to using a two-week decision-making timeframe, often exceeding his own deadlines. Meanwhile, the U.S. Navy’s third aircraft carrier strike group has already set sail for the Middle East. The market is digesting the expectation that the “war is nearing its end,” but the real turning point may only be confirmed after April 6, when Trump’s ceasefire order to Iran expires.
