S&P 500 futures slip as US-Iran tensions test fragile peace
S&P 500 futures dipped Wednesday as escalating US-Iran tensions cast fresh doubt on the Middle East ceasefire, marking a cautious start to the second half. Investors also awaited commentary from Federal Reserve Chair Kevin Warsh for clues on the rate path.
The June 17 Islamabad Memorandum暂停 hostilities and reopened the Strait of Hormuz to commercial shipping, but the truce has frayed. On June 28, the US and Iran agreed to halt a fresh exchange of strikes after days of cross-border fire. Two days later, the Wall Street Journal reported that Trump discussed all-out war options with Defense Secretary Pete Hegseth and General Dan Caine before opting to continue diplomatic talks, setting an Aug. 18 deadline for a nuclear deal.
Oil prices, which surged from below $70 a barrel before the war to an average of $103 in March, remain elevated as traders factor in the risk of renewed disruption to the Strait of Hormuz, through which about 20% of the world's oil passes. The US military's cost of the war has reached an estimated $40 billion, and Trump has requested $87 billion in supplementary funding from Congress, the majority tied to the conflict. The uncertainty weighed on equity futures as investors recalibrated geopolitical risk premiums.
The combination of elevated energy costs and geopolitical uncertainty creates a challenging backdrop for equities entering the second half. The war has already disrupted global supply chains, triggered fuel shortages in parts of Asia, and pushed up airfares as airlines passed on higher jet fuel costs. Warsh's remarks later Wednesday will be scrutinized for any signal on how the Fed views the growth-inflation trade-off amid the turmoil. The next catalyst for markets is any official statement from Washington or Tehran on the status of the 60-day ceasefire framework, with the Aug. 18 nuclear deal deadline looming as a key inflection point for both diplomacy and asset prices.
