US stock futures rise after Pakistan says US and Iran reached a peace deal

US stock futures moved higher after Pakistan announced that the US and Iran had reached a preliminary peace agreement, with a signing reportedly expected on June 19.
Market reaction was immediate:
S&P 500 futures: +0.8%
Nasdaq 100 futures: +1.3%
Dow futures: +0.6%
WTI crude: -5.0%
Brent crude: -4.0%
Gold: +2.0%
The rally appears to be driven by expectations that a US–Iran deal could reduce geopolitical risk, ease pressure on oil markets, and improve investor sentiment.
Still, the agreement has not been formally signed yet, so markets may remain volatile until more details are confirmed.
