Shipping Strikes In Hormuz Leave Both Sides With Economic Pain

The brief

The Strait of Hormuz is a narrow sea passage used by tankers carrying oil from the Middle East. It matters because the waterway connects regional producers with customers around the world. The article describes Iran’s attacks as part of a broader conflict with the US and an effort to maintain a blockade. Iran uses cruise missiles and drones against commercial shipping. Many weapons are fired toward a general area, then use radar or infrared seekers to guide themselves toward nearby ships. The attacks can damage engine rooms or hulls, even when they do not stop most vessels. Shipping continues, but danger has not disappeared. CENTCOM says about 95% of ships pass without incident, while the International Maritime Organization has recorded 121 incidents in Hormuz and the wider region since the war began. The attacks keep insurance and fuel costs elevated.

01

What is the Strait of Hormuz, and why are commercial ships using it being attacked?

The Strait of Hormuz is a narrow sea passage used by tankers carrying oil from the Middle East. It matters because the waterway connects regional producers with customers around the world. The article describes Iran’s attacks as part of a broader conflict with the US and an effort to maintain a blockade.

Iran uses cruise missiles and drones against commercial shipping. Many weapons are fired toward a general area, then use radar or infrared seekers to guide themselves toward nearby ships. The attacks can damage engine rooms or hulls, even when they do not stop most vessels.

Shipping continues, but danger has not disappeared. CENTCOM says about 95% of ships pass without incident, while the International Maritime Organization has recorded 121 incidents in Hormuz and the wider region since the war began. The attacks keep insurance and fuel costs elevated.

02

How much shipping is still moving through the strait, and how many incidents and deaths have been reported since the war began?

Oil shipments through the Strait of Hormuz are running at about 80% of their prewar level. That means the waterway remains open and commercially important, despite repeated attacks and security threats. Tanker owners are still accepting the risk because the financial rewards remain substantial.

The International Maritime Organization estimates 121 incidents in Hormuz and the wider region since the war began. Those incidents include attacks and other damage involving commercial vessels. At least 24 seafarers have been confirmed dead. The article also reports a record 28 open-source reports of shipping damage in October.

The figures show a serious but incomplete disruption. CENTCOM says around 95% of ships transit without incident, and no vessel has struck a floating mine, according to a US official. Still, damage to engine rooms or hulls can remove ships from service and raise the cost of every crossing.

03

Why can attacks raise oil prices and shipping costs even when about 95% of ships pass through safely?

Oil prices and shipping costs respond to risk, not only to actual losses. When attacks threaten a major oil route, insurers charge more to cover vessels, crews, and cargoes. Tanker owners also demand higher payments for entering the danger zone. Those extra costs can flow through to fuel buyers.

The article gives a striking example. In early October, it was more expensive in some parts of the world to hire a supertanker than to send a rocket into space. Shipments through Hormuz were still about 80% of prewar levels, but the associated danger had already inflated insurance costs.

The route therefore does not need to close completely to create economic pain. Even with about 95% of ships passing safely, repeated attacks keep uncertainty high. If attacks intensify or vessels stop accepting the risk, available supply could fall further, putting additional pressure on fuel prices and trade.

04

How are the US blockade of Iran’s oil exports and Iran’s attacks on shipping connected to the broader economic standoff?

The US blockade has sharply reduced Iran’s oil income, a key source of military funding. The article says only a tiny fraction of Iran’s prewar exports of 2 million barrels per day is leaving through land routes. That pressure has severely damaged Iran’s roughly $300 billion economy.

Iran’s response is to keep attacking commercial vessels in the Strait of Hormuz. The goal is not necessarily to stop every ship. Even intermittent attacks raise insurance, tanker, and fuel costs. That creates political pressure in the US, where higher fuel prices are becoming a problem before the midterm elections.

The result is a painful economic standoff. Iran is weakened but retains enough missile components to continue harassment. The US can protect and organize ship transits, and may resume airstrikes, but those strikes may not eliminate Iran’s ability to attack. Neither side has an easy, guaranteed solution.

05

What alternative routes or methods could oil producers and shippers use if the Strait of Hormuz became too dangerous, and why are those alternatives limited?

If Hormuz became too dangerous, oil producers and shippers could try land pipelines, alternate export terminals, stored supplies, or longer maritime routes around the region. These methods could reduce exposure to the strait. The article, however, does not describe a specific alternative system or say how much capacity any option has.

The article does state that only a tiny fraction of Iran’s prewar 2 million barrels per day is leaving through land routes. That example shows why overland movement cannot quickly replace normal seaborne exports. A rerouted tanker journey would also require more time, fuel, and insurance, making each cargo more expensive.

For now, tankers continue using Hormuz at about 80% of prewar levels. Owners are earning tens of millions of dollars per transit, and crews can receive several months’ pay for a few dangerous days. Those rewards are keeping trade moving, but a major escalation could change that balance.

06

Why can Iran continue launching attacks despite US airstrikes and the destruction of much of its long-range tracking capability?

US airstrikes have severely weakened Iran’s ability to manufacture anti-ship weapons at scale. They have also destroyed much of Iran’s ability to track targets beyond visual range of its shores. But those losses have not eliminated Iran’s capacity to launch attacks against ships.

Iran retains a stockpile of missile components and can assemble anti-ship weapons. Its military planning has emphasized resilience, redundancy, and stockpiling for decades. Many missiles are fired blindly or toward an area where planners expect ships to be. Radar or infrared seekers then guide them toward nearby targets.

This makes the attacks less precise but still disruptive. Iran does not need a high tempo of strikes to keep risk and insurance costs elevated. The article says its manufacturing capacity is damaged, not gone, and its forces still use cruise missiles and drones. Continued harassment therefore remains possible even under sustained pressure.

07

How do risk, insurance, supply, and demand interact to turn a threat to one shipping route into higher fuel prices around the world?

Risk changes the economics of shipping before supply actually disappears. Insurers charge more when a vessel may be attacked. Owners then seek higher freight payments, and crews demand compensation for dangerous work. Those costs become part of the price of delivering oil, even when most ships complete their journeys.

The article shows this mechanism in Hormuz. About 80% of prewar shipping still passes through the strait, and CENTCOM says about 95% of ships transit without incident. Yet insurance costs have risen, and supertankers became extraordinarily expensive to hire in early October. A damaged engine room can also take a vessel out of service.

Demand for fuel does not vanish simply because one route becomes risky. Buyers still need oil, so they compete for available cargoes and safer transport. If supply falls or ships withdraw, prices can rise further. The current rewards are keeping trade moving, but escalation could make the route uneconomic.
