The closure of the Strait of Hormuz amid the escalating conflict involving the United States, Israel and Iran is casting a growing shadow over Nigeria’s import dependent economy, with importers warning that the disruption could soon push up shipping costs, delay cargo and raise prices for consumers.

The strait, one of the world’s most strategic maritime routes, carries a large share of global oil and cargo shipments linking Asia, the Middle East, Europe and Africa. As tensions rise and shipping activity slows in the corridor, Nigerian importers say the immediate impact may not yet be fully visible, but the ripple effects across global supply chains are already beginning to build.

Anil Sahgal, chief operating officer of the mobility division at Kewalram Chanrai Group, said the conflict is still in its early days but warned that the disruption in shipping routes will soon be felt across markets.

“Any conflict of this nature usually has a delayed impact,” he said. “The real effect on supply chains often begins to appear after three to five weeks.”

According to Sahgal, hundreds of vessels have reportedly been caught in the uncertainty surrounding the strait, either waiting for safe passage or being forced to reroute.

“When vessels are stuck or delayed, it disrupts the entire shipping cycle,” he said. “A ship that is supposed to unload cargo in one place and then move on to another assignment cannot proceed. That delay spreads across the global logistics chain.”

The scale of the disruption is already raising alarm within the global shipping community.

The International Maritime Organisation said thousands of seafarers and vessels are being affected by the worsening security situation in the region. The United Nations maritime agency warned that the crucial Strait of Hormuz shipping corridor, which forms the gateway to the Persian Gulf, has effectively become unsafe due to the threat of military strikes.

Arsenio Dominguez, International Maritime Organisation secretary general, said the closure of the sea lane could have serious global consequences.

More than 3,000 vessels and about 20,000 seafarers are currently stranded across parts of the Middle East due to the ongoing conflict, according to the organisation.

Dominguez warned of the global knock on effects of the disruption, noting that about 20 percent of the world’s oil passes through the corridor.

He urged countries to seek diplomatic solutions to reduce tensions and restore safe navigation in the region.

For Nigerian importers, the most immediate consequence is rising freight costs.

Sahgal noted that shipping charges from major trading partners such as China have already begun to increase, in some cases by between 10 and 15 percent.

“If the conflict continues, the increase could become much higher,” he said. “We have seen situations in the past where freight costs doubled during periods of global disruption.”

Insurance premiums for maritime shipments are also climbing as insurers reassess the risks of operating near conflict zones.

Sahgal explained that insurance costs for sea voyages, which previously averaged about $200,000 for large shipments, are now rising sharply as companies factor in the growing uncertainty.

“These additional costs will not disappear,” he said. “Eventually they will be transferred to the final price of goods.”

Manufacturers and traders in Nigeria say they are already beginning to feel the early signals of the crisis.

Frank Ike, a business executive involved in manufacturing supply chains, said the closure of the strait could affect not only shipping routes but also energy prices and industrial production.

“About twenty percent of the world’s oil passes through that corridor,” he said. “Once that flow is disrupted, crude oil prices begin to rise and that affects everything.”

According to Ike, the impact is already visible in the cost of petrochemical materials used by manufacturers.

“For companies producing plastics and other related goods, the price of petrochemicals has started rising almost immediately,” he said.

“Energy costs feed into every part of the production chain.”

He warned that if the conflict drags on, Nigerian manufacturers could face rising production costs that will ultimately be passed on to consumers.

The crisis is also beginning to disrupt global travel and logistics.

Airspace restrictions across parts of the Middle East have forced airlines to reroute flights, affecting passenger travel and cargo movement.

“A lot of flights pass through the Middle East corridor,” Ike said. “With parts of that airspace closed, aviation and cargo operations are also feeling the pressure.”

For many Nigerian importers, however, the most immediate concern is the possibility of longer shipping routes.

Benita Adelore, general manager of Leventis Motors, said businesses importing goods must now prepare for longer delivery times and higher logistics costs.

“If the usual route is closed or unsafe, shipping companies will have to take alternative routes,” she said. “Those routes are longer and that means additional days at sea and higher shipping costs.”

Such delays can have serious commercial consequences, especially for businesses operating with tight delivery timelines.

“When customers expect goods within a certain time and shipments are delayed for months, it can damage trust between businesses and their clients,” Adelore said.

She added that longer transit times could also lead to higher shipping charges and additional port related costs.

Adewale Akinlaja, director of key Account – FOTON motors Nigeria, said the situation may not yet have fully affected goods already close to Nigerian ports, but warned that future imports could face serious disruptions if the conflict persists.

“Right now some shipments that are already close may still arrive as planned,” he said. “But for new imports, businesses will have to prepare for longer routes, higher freight costs and more expensive cargo charges.”

He noted that many importers have little control over the situation and may have to absorb some of the costs.

“Shipping companies will simply pass the additional cost to the importer,” Adewale said. “At the end of the day, those costs will also reach the final consumer.”

The uncertainty is also pushing many businesses to rely more heavily on insurance to reduce financial risks tied to shipment delays or disruptions.

“Insurance becomes an important protection,” he said. “Even if delays happen, businesses can at least protect themselves from major financial losses.”

For now, importers say the scale of the disruption will largely depend on how long tensions in the region continue.

Some shipments already on the way to Nigeria may still arrive on schedule, but new consignments could face longer transit times if the security situation around the strait does not improve.

Beyond the immediate disruption, the crisis has revived long standing concerns about Nigeria’s heavy dependence on imported goods and industrial inputs.

Ike said the situation should push policymakers to accelerate efforts to strengthen domestic production.

“We export many raw materials and then import finished products made from those same materials,” he said. “If we develop stronger local manufacturing, shocks like this will not affect our economy so severely.”

For now, importers are watching developments closely and hoping diplomatic efforts will calm tensions before global trade routes face deeper disruption.

But with shipping costs rising, insurance premiums climbing and oil markets already reacting, many businesses fear the economic consequences of the crisis may soon reach Nigerian consumers.
