Global oil prices jumped after the U.S. military launched strikes against Iran and President Donald Trump declared the cease-fire over [1, 2].
The escalation threatens the stability of Middle East shipping routes and the Strait of Hormuz, raising fears of significant global supply disruptions [1, 3].
U.S. military strikes against Iran occurred on July 7 [4]. Following these actions, U.S. oil prices jumped nearly 3% in early trade [4]. Market volatility increased further as President Trump threatened to bomb Iran, which saw prices rise more than 4% [3].
On July 8, the situation intensified when Trump announced the end of the interim agreement [2]. "The ceasefire is over," Trump said [2].
Following that statement, oil prices surged more than 6% [2]. Some market data showed WTI and Brent crude trading 6.5% higher [5]. This spike reflects investor anxiety over a potential full-scale conflict in a region critical to energy exports.
By Thursday, July 9, the immediate volatility appeared to stabilize, with some reports indicating oil prices were little changed [1]. Despite this brief plateau, the breakdown of the truce has left energy markets on high alert.
Investors are closely monitoring the Strait of Hormuz, a narrow waterway where a large portion of the world's oil passes. Any Iranian retaliation against shipping lanes could trigger further price shocks, and global economic instability [1, 3].
“"The ceasefire is over."”
The collapse of the interim agreement between the U.S. and Iran removes a critical diplomatic buffer, shifting the conflict from a fragile truce to active military engagement. Because the Strait of Hormuz is a global energy chokepoint, the market is now pricing in a higher risk of supply shocks. This volatility suggests that global oil prices will remain sensitive to every military movement and diplomatic statement coming from both Washington and Tehran.
