During European trading hours on Tuesday, futures for major US stock indices showed notable gains amid easing tensions in the Middle East. According to FX Street, Dow Jones futures increased by 0.29%, trading around 52,220, reflecting cautious optimism among investors.

S&P 500 futures also advanced, rising 0.44% to trade near 7,520, while Nasdaq 100 futures led the gains with a 1.12% increase, reaching approximately 29,100. These movements suggest a positive risk sentiment returning to the markets as geopolitical concerns momentarily subside.

For Japanese investors, the uptick in US futures is significant as it may influence Tokyo’s equity market opening and affect the yen-dollar exchange rate, given Japan's close trade and financial ties with the United States.
