US stock futures tumble as Trump says Iran deal is ’over’; oil climbs

US stock futures saw a significant tumble in pre-market trading, while crude oil prices surged following President Trump's declaration that the Iran nuclear deal is 'over'. This move signals a dramatic shift in US foreign policy towards Iran and has immediate implications for global energy supplies and geopolitical stability.

The previous Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), imposed restrictions on Iran's nuclear program in exchange for sanctions relief. Trump's decision to withdraw from the agreement and re-impose sanctions is expected to target Iran's oil exports, which could remove a substantial amount of crude from the global market.

This development directly impacts oil futures, particularly WTI and Brent crude, as supply concerns emerge. Beyond energy, the broader equity market is reacting to increased geopolitical risk and potential economic uncertainty, leading to a flight-to-safety dynamic that could benefit traditional safe-haven assets. The immediate focus for traders will be on the magnitude of the oil price rally and the duration of equity market weakness, as well as any retaliatory actions or statements from Iran or other international powers.
