United States stock futures edged lower on Sunday night (Monday AEDT), following a fourth consecutive week of declines on Wall Street, as escalating tensions between the United States and Iran weighed on investor sentiment.
By 9:55 am AEDT (10:55 pm GMT), futures tied to the Dow Jones Industrial Average slipped 0.1%, while S&P 500 futures fell 0.2% and Nasdaq-100 futures declined 0.3%.
The cautious tone comes as the conflict involving Iran entered its fourth week, with tensions escalating over the weekend.
U.S. President Donald Trump issued a fresh warning, threatening potential strikes on Iranian power infrastructure if the Strait of Hormuz, a critical route for global oil shipments, is not reopened.
Tehran responded by warning it would target U.S. infrastructure across the Gulf region, including energy and desalination facilities, should Washington proceed with military action.
Investors are also turning their attention to upcoming economic data, with the S&P Global Flash U.S. purchasing managers' index (PMI) report due on Tuesday, which could provide further insight into business activity amid the current uncertainty.
From a technical perspective, market participants are closely watching key support levels. The S&P 500 recently broke below its 200-day moving average for the first time since May, a development that may signal weakening momentum.
Last week, the Dow and Nasdaq each declined around 2%, while the S&P 500 fell 1.5%. The Dow’s four-week losing streak marks its longest run of weekly losses since 2023.
