US stock futures fell on Monday amid escalating geopolitical tensions following US President Donald Trump's announcement of a blockade on the Strait of Hormuz, coinciding with the failure of peace talks between the United States and Iran over the weekend to reach an agreement to end the ongoing conflict.

The breakdown of negotiations in Islamabad has brought renewed anxiety to global markets, with growing fears that the war will last longer than expected, which has directly impacted rising oil prices.

This increase is an additional source of pressure on global economies, amid concerns about rising energy costs and their impact on inflation rates and economic growth.

In the context of trading, futures contracts for major US indices recorded a notable decline during the pre-market opening period.

Dow Jones Industrial Average futures fell by about 0.54%, losing nearly 258 points, to trade near the 47,871 point level.

S&P 500 futures fell 0.64% to 6,811.50, while Nasdaq 100 futures dropped 166 points, or 0.66%, to trade near 25,115.25.

This performance reflects the cautious state of investors, with increasing pressures resulting from rising oil prices and escalating geopolitical risks, prompting markets to reprice expectations for global economic growth in the coming period.
