US Stock Futures Slip as Iran Tensions and Hot Inflation Data Pressure Wall Street

U.S. stock index futures edged lower Tuesday night as investors reacted to escalating geopolitical tensions involving Iran and stronger-than-expected inflation data that weighed heavily on Wall Street sentiment. Concerns about rising consumer prices, combined with profit-taking in major chipmaking stocks, pushed markets away from recent record highs.

S&P 500 Futures declined 0.1% to 7,419.25 points, while Nasdaq 100 Futures slipped 0.16% to 29,124.75 points. Dow Jones Futures also traded slightly lower at 49,853.0 points during late evening trading. The cautious market mood followed a weak regular trading session where technology and semiconductor shares led losses.

The latest U.S. Consumer Price Index (CPI) report showed inflation accelerating in April, reaching its highest level since May 2023. Core CPI also exceeded expectations, reinforcing investor concerns that ongoing conflict in the Middle East, particularly the Iran war, is driving up energy prices and increasing overall costs for consumers.

Higher oil and gas prices fueled speculation that the Federal Reserve could consider another interest rate hike later this year, although many analysts still expect rates to remain unchanged for the remainder of 2026. Investors are also closely monitoring leadership changes at the Federal Reserve as Jerome Powell’s term nears its end. President Donald Trump’s reported support for Kevin Warsh as the next Fed chair has added another layer of uncertainty to financial markets.

Technology stocks came under pressure after weeks of strong gains. The Philadelphia Semiconductor Index dropped 3% as investors locked in profits from the recent rally in chipmakers. The Nasdaq Composite ended Tuesday down 0.7%, while the S&P 500 lost nearly 0.2%.

Meanwhile, tensions between the United States and Iran continue to worry investors. Trump recently stated that ceasefire negotiations remain fragile and confirmed that U.S. naval measures against Iran will continue. Markets are now watching Trump’s upcoming China visit, where discussions with President Xi Jinping on trade, artificial intelligence, Taiwan, and Iran could significantly impact global markets.
