US stock index futures rallied sharply following President Donald Trump's announcement of a two-week ceasefire in the Iran conflict. The market reacted positively to the diplomatic breakthrough, with investors showing relief that the potentially destabilizing situation in the Middle East might be de-escalating.

Major indices saw immediate gains in pre-market trading as the ceasefire news spread. The S&P 500 futures climbed approximately 1%, while NASDAQ futures rose by a similar margin. Oil prices pulled back as the reduced risk of supply disruptions became clear.

The two-week ceasefire represents a brief pause in hostilities rather than a permanent solution, yet the market response demonstrates how sensitive investors are to geopolitical developments. Business leaders welcomed the news as potentially reducing uncertainty in the Middle East.
