Hormuz Day 11: Iran Lays Mines as Three Ships Hit
Iran begins mining the Strait of Hormuz, converting the drone-enforced closure into a semi-permanent minefield. Three vessels struck in a single day. SPR relief fades as the market does the math.
- Iran has begun laying mines in the Strait of Hormuz, converting a reversible drone closure into a semi-permanent minefield that will require weeks to months of clearance even after a ceasefire.
- Three vessels were struck by projectiles on March 11, the highest single-day attack rate of the crisis. Iran's 37th wave of missiles and drones hit all six GCC nations, including Camp Arifjan and Dubai International Airport.
- The SPR-driven Brent crash to $88 is reversing as the market prices in mine risk. Expect $95+ this week, $105-110 by March 18 if clearance operations stall.
