What is happening at sea
Iran's sporadic strikes on merchant shipping have collided with US efforts to throttle Tehran's oil income, turning the Strait of Hormuz into an economic pressure point. Washington's squeeze on Iranian crude has hit a critical military funding stream and weighed on an economy of roughly $300 billion, with only a thin slice of the prewar 2 million barrels a day now trickling out over land.
Even so, traffic through the strait continues. Shipments are running at about 80% of prewar levels, and tankers are still hauling Middle East barrels. The risk premium is doing the price work: insurance has climbed, and in early October, chartering a supertanker in some regions temporarily topped the cost of launching a rocket into space.
The scale of incidents and how transits are protected
Open-source tallies recorded at least 28 cases of vessel damage in the strait in October. A US official with direct knowledge said Iran has not increased how often it fires, but more severe hits have led to more reports, with about one quarter of the incidents in the first two weeks targeting engine rooms that can put ships out of action. Since the war began, the International Maritime Organization counts 121 incidents across Hormuz and nearby waters, including 24 confirmed seafarer fatalities.
According to US Central Command, the vast majority of Iranian attacks are thwarted or miss, and roughly 95% of vessels transit without incident. The same US official said Iran is using both cruise missiles and drones. In response, US forces are coordinating transits and providing protection, mostly from aircraft overhead. The military is in direct contact with the tanker industry, sharing updates and aligning on timing, routes and convoy sizes, then assigning assets to monitor voyages and shoot down threats if needed.
No ship has hit a floating mine while crossing the strait, the US official said. Iran said in late October that a mine struck a tanker, and the UKMTO later reported on Friday that another vessel suffered damage from charges attached to its hull.

Capabilities, constraints and what strikes can do
Per Jim Lamson - a visiting research fellow at King's College London and a former CIA analyst with a focus on Iran and the Middle East - Tehran can continue assembling anti-ship systems from stored missile components, even as US airstrikes have severely cut back Iran's capacity to produce them in large quantities. "They have been planning for a long-term asymmetric conflict with the US for decades," Lamson said. "Things like building in resilience, building in redundancy, building in stockpiling - these have been part of their military culture."
John Miller, a former CENTCOM commander and retired US Navy vice admiral, said Iran can keep attacking ships in Hormuz as long as it wants to sustain a blockade, framing the choice as making them unwilling or unable. He added that much of Iran's ability to track targets beyond sight over the last eight months has been largely destroyed. That leaves weapons often launched toward general areas, with radar or infrared seekers directing them to nearby objects at the end. To counter those, aircraft use low cost munitions such as APKWS, where a BAE Systems Plc guidance kit is about $20,000, while high-cost ship-based interceptors such as Raytheon's SM-6 and the SM-3 Block IIA are held back primarily to counter ballistic missile threats.
In recent days, Trump has indicated he plans to restart attacks on Iran after the Nov. 3 midterm elections. Even so, Emma Salisbury - who holds a non-resident senior fellowship at the Foreign Policy Research Institute and an associate fellowship at the Royal Navy Strategic Studies Centre - said it is not clear that airstrikes will change conditions in the strait, especially against an adversary that has spent decades shielding key capabilities from such raids.
Prices, politics and your portfolio
Higher risk and insurance around Hormuz have kept US fuel prices elevated, and the political blowback is building ahead of the midterms. Iran does not need a rapid tempo of attacks to keep oil supported, and Ziad Daoud, chief emerging markets economist at Bloomberg Economics, estimates a flare up could push crude into the 120 to 130 dollar range. He also wrote that both sides "may prefer a brief conflict to improve their negotiating power."
Despite the dangers, the tanker market is still moving barrels at near prewar levels. Owners can earn tens of millions of dollars on these runs, and crews are pocketing months of pay for just a few days in high-risk waters, which is keeping voyages going. The bottom line: flows through Hormuz mostly continue, but at a higher cost that props up prices and leaves your energy exposure sensitive to any escalation.
