## Executive Summary
Global futures tumble and oil prices surge following reports of military strikes near the Strait of Hormuz.

## Intelligence Brief
US stock futures for the Dow, S&P 500, and Nasdaq are declining in response to escalating military activity involving the United States and Iran. Reports indicate that Iran has stated the Strait of Hormuz is closed, and new strikes have been reported in the region, triggering a jump in oil prices. SK Hynix is also noted to be diving in Seoul trading.


Coverage from Barron's, Yahoo Finance, and MarketWatch emphasizes the correlation between the exchange of fire and negative market sentiment. MarketWatch specifically highlights the closure of the Hormuz Strait as a key factor, while Barron's and Yahoo Finance focus on the rise in oil and the slipping of major stock indices. Further reports are expected regarding the status of the Strait of Hormuz and the extent of the military engagement.


Market participants will likely monitor the trajectory of oil prices and the performance of Asian tech stocks, specifically SK Hynix, as the situation develops.
