Stock market today: Dow, S&P 500, Nasdaq futures fall as US-Iran war escalates, inflation jitters return

US stocks experienced a mixed trading session on Wednesday, with the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite futures declining amid escalating tensions between the United States and Iran, as well as renewed worries about inflation. The Dow Jones rose by approximately 0.6%, the S&P 500 increased by roughly 0.5%, and the Nasdaq Composite gained around 0.4%, following a losing day on Wall Street.

The reescalation of the war in Iran contributed to the market's decline. Oil prices, particularly Brent and WTI crude, remained elevated near $95 and $90 per barrel, respectively, providing some relief from previous losses. However, the volatile situation and the potential for increased military action kept investors cautious.

Fed officials, particularly New York Fed President John Williams, offered some reassurance to market participants. Williams stated that there were no clear signs that a September rate hike would be necessary to curb inflation. This statement, along with the modest recent gains in long-term bond yields, suggested that the economy might be strong enough to support higher bond prices rather than rising inflation expectations.

Despite the overall positive sentiment, market participants remained cautious. Recent ADP data showed that the U.S. private sector added only 38,000 jobs in August, slightly below economists' estimates of 47,000 positions. Additionally, earnings reports from Broadcom and Snowflake were anticipated to be released later in the trading day, adding to the uncertainty surrounding the market's direction.
