Iran mulls tactical shift in Hormuz attacks before key US vote

The Strait of Hormuz is a vital sea passage connecting the Persian Gulf region with the Gulf of Oman and wider international waters. It matters because large volumes of energy cargo move through it. Before the war, about one-fifth of global oil and liquefied natural gas trade passed through the strait.

Its importance is clear from the current crisis. Iran has restricted passage and attacked vessels it considers violators. The threats have severely reduced traffic, although some oil continues to transit. Tankers still using the route face higher shipping and insurance costs.

The strait is now a major pressure point for energy markets. Iran’s officials say Tehran may expand operations into the Gulf of Oman and waters farther away. They also say complete closure could come soon, raising the risk of wider disruption to global trade.

Iran is reportedly adopting a faster and broader campaign against ships that it considers in violation of its restrictions. Two Iranian officials said the changes began about 10 days ago and involved both the type and pace of attacks. They said the goal includes raising pressure on the United States and influencing its midterm election debate.

One important change followed U.S. strikes that destroyed much of Iran’s radar capability. A U.S. military official said the IRGC began using unarmed spotters in small boats to locate possible targets, including U.S. naval vessels. In one incident, a dhow was destroyed after its occupants were told to abandon ship.

Iran also reportedly plans to widen operations beyond Hormuz. Recent incidents have involved ships near Qatar and the United Arab Emirates. Maritime sources said attacks on commercial vessels recently reached their highest level since the war began.

Before the war, the Strait of Hormuz carried about one-fifth of global oil and liquefied natural gas trade. The article does not provide a separate percentage for oil alone. Instead, it gives a combined figure for oil and LNG moving through this strategic waterway.

That share explains why the strait matters beyond the countries around it. Iran’s threats and attacks have severely curtailed traffic, although some oil continues to pass. The reduced flow has already driven up oil prices, according to the article.

The risk could grow if Iran expands attacks into nearby waters or closes the passage completely. Iranian officials said Tehran was moving toward preventing any vessel that violates its restrictions from passing. The article reports that one official called complete closure soon possible.

Attacks or restrictions can raise oil prices by slowing the flow of energy to global buyers. When a major route carries about one-fifth of oil and LNG trade, even partial disruption can make available supplies seem tighter. Buyers may then pay more for cargoes that can still move.

The danger also raises the cost of transporting those cargoes. Tankers may face delays, rerouting, security measures, or a greater chance of damage. Insurers charge more when the probability and potential cost of an incident increase. The article reports that high shipping and insurance costs are complicating efforts to restore normal traffic.

Expectations can amplify the effect before a complete shutdown occurs. Threats of more attacks or closure may prompt traders to bid up prices and companies to delay voyages. The article says global energy markets remain exposed to further disruption around Hormuz.

Iran’s actions could affect the U.S. midterm elections by keeping oil prices high and making the war more expensive politically. The article says the conflict costs $3 billion each month. That price tag has become a key issue on the campaign trail because voters and lawmakers are debating the war’s consequences.

Iranian officials said one purpose of the new strategy is influencing the U.S. vote. They said Tehran wants to frustrate U.S. and allied efforts to bring down global oil prices. One official said Iran would push prices away from falling whenever Washington appeared close to that goal.

The political effect is uncertain, but the pressure is immediate. President Donald Trump has been weighing next steps and said he will not attack again before the vote. Meanwhile, the U.S. is blockading Iranian ports and extending sanctions to pressure Tehran toward a deal.

If Hormuz becomes unsafe, exporters and tanker operators can use alternative routes where geography and infrastructure allow. They may move oil through pipelines to ports outside the affected area, use other export terminals, draw on stored supplies, or ship smaller volumes through longer routes. These options cannot necessarily handle the same volume or speed.

The article does not identify specific alternative pipelines, ports, or routes. It does report that some oil has continued through the strait despite attacks. It also says Iran may expand operations into the Gulf of Oman and farther waters, which could make nearby alternatives riskier.

A complete closure would therefore be difficult to offset quickly. Longer voyages would consume more time and fuel, while limited infrastructure could create bottlenecks. Exporters might rely more on inventories and alternate transport, but global markets would still face tighter supply and higher costs. These operational alternatives are established possibilities, not details provided by the article.

Supply and demand set the basic direction of oil prices. If buyers want more oil than producers can deliver, prices tend to rise. If supply comfortably exceeds demand, prices tend to weaken. A disruption at Hormuz can reduce or delay deliveries, making available supply tighter even if global demand has not changed.

Expectations add another layer. Traders may buy oil or contracts when they fear future attacks, closure, or longer shipping delays. That can lift prices before a physical shortage appears. The article reports that threats and attacks have already driven up prices and that high shipping and insurance costs complicate normal traffic.

The size and duration of the disruption determine how lasting the effect becomes. Continued transit, alternative supplies, stored inventories, or a negotiated settlement could limit pressure. A wider campaign or complete closure would likely intensify it. The article says markets remain exposed to further disruption.
