U.S. stock futures experienced a slight decline on Thursday, following a previous session's rally, as concerns resurfaced regarding the stability of the Middle East ceasefire. President Donald Trump reiterated his commitment to maintaining military presence in the region until a peace agreement with Iran is reached, warning of significant escalation if compliance is not met. This uncertainty, particularly regarding energy flows through the Strait of Hormuz, contributed to a rebound in oil prices, though they remained below $100 a barrel. Investors are now shifting their focus to the upcoming release of U.S. personal consumption expenditure (PCE) figures for February, the Federal Reserve's preferred inflation indicator, with economists anticipating it to remain unchanged at 2.8%.
