Iran has announced the closure of the Strait of Hormuz, a move that immediately sent energy markets into a risk-off posture.
The Revolutionary Guard cited alleged violations of the ceasefire agreement by the United States and Israel as the primary justification for the blockade.
This assertion marks a significant escalation in the ongoing conflict, transforming diplomatic friction into a direct threat to global energy supply chains.
Brent crude prices opened sharply higher in response to the news, reflecting immediate concerns over supply disruption.
The Strait of Hormuz serves as a vital artery for global oil trade, and any credible threat to its openness triggers a premium on energy assets.
Traders are now pricing in heightened volatility as the potential for physical disruption moves from theoretical risk to active operational concern.
