US-Iran Diplomatic Collapse Triggers Blockade of Strait of Hormuz, Sending Oil Above $100

Global energy markets and equity futures reacted sharply on Sunday evening following the collapse of diplomatic talks between the United States and Iran. The failure to reach an agreement regarding the status of the Strait of Hormuz has led to a direct and severe escalation in regional tensions. President Donald Trump announced a blockade of the crucial waterway, a move that threatens to disrupt a significant portion of the world's seaborne oil trade. The Strait of Hormuz serves as one of the most critical chokepoints in the global energy infrastructure, and any restriction on transit typically triggers immediate and aggressive price spikes in crude oil. In immediate response to the news, crude oil prices have surged past the $100 per barrel threshold. Simultaneously, stock-market futures indicated a sharp downward trajectory, as investors price in the risks of massive supply chain disruptions and the potential for a broader military conflict. The combination of skyrocketing energy costs and extreme geopolitical instability is expected to create a pervasive 'risk-off' environment. Market participants are likely to rotate out of equities and into safe-haven assets as the financial world assesses the duration and severity of the blockade and its impact on global GDP.
