Iranian drone attacks could disrupt the Strait of Hormuz for months, according to intelligence sources and military analysts. The size of Iran's missile stockpile is unknown, with estimates ranging from 2,500 to around 6,000 estimates. The country is a major drone manufacturer and has the industrial capacity to produce around 10,000 per month. How much of Iran’s arms remains could determine the course of the war. Energy prices have also risen, with Brent crude rising 12% and a European natural gas benchmark up about 50% so far this week. If missiles and drones run out, Iran could deploy sea mines.
