The escalating Strait of Hormuz closure has left dozens of Indian and South Korean oil tankers stranded in and around the Persian Gulf, intensifying concerns about global energy security and supply chain disruptions.
India-flagged ships, alongside several South Korean crude carriers, are currently unable to transit through the critical maritime chokepoint, which remains de facto closed to tanker traffic.
The Strait of Hormuz is one of the world’s most vital oil corridors, linking the Persian Gulf with the Gulf of Oman and the Arabian Sea. A significant portion of globally traded crude oil passes through the narrow channel each day, making any disruption immediately consequential for import-dependent economies.
According to local media reports, as many as seven crude oil tankers from South Korean refiners are currently stranded in the strait. The situation poses an immediate challenge for South Korea, which relies entirely on imported crude and natural gas to power its economy.
Industry executives warn that delays in shipments could ripple through the refining and petrochemical sectors.
One refinery official revealed that a single stranded tanker has already loaded two million barrels of crude oil from the Middle East. That cargo alone represents roughly one day’s worth of oil consumption in South Korea, underscoring the scale of the disruption.
Corporate leaders have begun calling for urgent discussions with the government on contingency measures, including the possible release of crude from national reserves to cushion the impact of prolonged delays.
Kim Chang-beom, standing vice chairman of the Korea Enterprises Federation, voiced deep concern over the situation during a parliamentary meeting in Seoul.
“If the Iran situation is prolonged, it could pose a significant burden across the board, from energy and shipping industries to Middle East export projects.”

His remarks reflect growing anxiety within South Korea’s industrial base about the broader economic implications of the crisis.
Indian Ships and Crew Also Affected
India, another major energy importer, is similarly grappling with disruptions linked to the Strait of Hormuz closure.
An Indian official familiar with the matter disclosed that several sailors, are stranded in the Persian Gulf, the Gulf of Oman and adjacent waters.
“A total of 37 Indian-flagged ships with 1,109 sailors are stuck in the Persian Gulf, the Gulf of Oman and the adjoining sea areas due to the closure of the key shipping route through the Strait of Hormuz.”

The vessels include oil tankers and other commercial ships that depend on safe passage through the strait for global trade routes.
The presence of more than a thousand crew members aboard the stranded ships adds a humanitarian dimension to the crisis, as extended delays increase risks and operational costs.
Shipping data suggests a dramatic decline in tanker movements through the strait in recent weeks.
Energy analytics firm Vortexa reported that daily tanker transits have plunged from around 40 vessels per day in January to just one tanker completing the passage on March 3.
The sharp drop illustrates how severely maritime activity has been curtailed.
For global oil markets, such a bottleneck can tighten supply, drive up freight rates and push up crude prices, particularly if the disruption persists.
Energy Security at Risk
The Strait of Hormuz closure comes at a sensitive time for global energy markets, which are already contending with geopolitical tensions and fluctuating crude prices.
For countries like South Korea and India, which lack significant domestic oil production, the stakes are particularly high. Extended shipment delays could force refiners to adjust production schedules, draw down reserves or seek alternative suppliers at potentially higher costs.
Executives in South Korea have already signaled the possibility of tapping strategic reserves if the situation deteriorates further.
Beyond crude supply, disruptions could also affect liquefied natural gas shipments, petrochemical feedstocks and broader trade flows between the Middle East and Asia.
Shipping companies face rising insurance premiums and rerouting costs, while exporters dependent on Middle Eastern markets may encounter logistical hurdles.
If tensions ease and maritime traffic resumes, markets may stabilize relatively quickly. However, a prolonged standoff could deepen supply concerns and amplify pressure on global energy prices.
As dozens of oil tankers and more than a thousand crew members remain stranded, the Strait of Hormuz closure stands as a stark reminder of how geopolitical flashpoints can reverberate across global energy supply chains in a matter of days.
