Dow Jones, S&P 500, and Nasdaq 100 futures all declined during European trading hours on Wednesday, reflecting investor caution amid escalating US-Iran tensions. According to FX Street, Dow Jones futures fell 0.30% to trade around 52,290.

S&P 500 futures dropped 0.38%, trading near 7,520, while Nasdaq 100 futures saw the steepest decline of 0.85%, falling to about 29,070, FX Street reported. The declines suggest increased risk aversion in the markets as geopolitical concerns weigh on sentiment.

For Japanese investors, these movements underscore the importance of monitoring global geopolitical risks, which can influence currency pairs and equities tied to US market performance.
