U.S. stock futures declined following renewed military actions against Iran, coinciding with rising oil prices which surpassed $90 per barrel. The geopolitical unrest has heightened expectations for interest rate hikes by the Federal Reserve, particularly after recent hawkish comments from Fed Governor Warsh. Consequently, Asian markets also reflected this downward trend, as stocks slipped under pressures from high oil prices and growing fears over monetary policy tightening. Investors are closely monitoring economic data for indications of job market conditions, as the probability of a rate hike remains significant amid ongoing inflation concerns.
