According to a report by Seoul Shinmun, as the blockade of the Strait of Hormuz has continued for over a month because of the aftermath of the war between the US and Iran, Middle Eastern oil-producing countries are discussing with the government a plan to store some crude oil at Korea's storage bases. If they move crude oil outside the Middle East in advance, they can continue exports more steadily even if war or a blockade lasts longer. The Korean government also said recently that requests for talks have been continuing from several oil-producing countries. Korea is already carrying out international joint stockpiling projects with Saudi Arabia, the UAE, and Kuwait. In this structure, overseas oil is stored at Korea National Oil Corporation facilities, and Korea gets rental income and the right to import first in an emergency. The government said it will spend 155.4 hundred million KRW to buy an additional 104ten thousand barrels of reserve oil, and it also plans to put in 3 hundred million KRW for maintenance of storage bases and design for facility expansion.
원문 보기Why Middle Eastern oil-producing countries are sending love calls to Korea
The point of this news is not simply, 'Where should we store oil?' It is about making a safe warehouse in advance outside the route that can be blocked when war happens. From the view of Middle Eastern oil-producing countries, if crude oil stays only inside the Strait of Hormuz, ships may not be able to leave even if they want to sell it.
But Korea has quite special conditions. It is a big oil importing country, so there is real demand, industrial ports like Ulsan and Yeosu are well prepared, and the storage bases run by Korea National Oil Corporation are already operating. Simply said, it is not a country with only warehouses, but a country with a market and ports where oil can be sold right away.
So Korea looks to Middle Eastern oil-producing countries like a 'safe temporary storage place' and at the same time a 'forward sales base for Northeast Asia.' If Singapore is a global trading hub, Korea's strength is that real demand, storage infrastructure, and government-to-government cooperation are tied together at once.
Oil-producing countries want to spread geopolitical risk, and Korea wants both energy security and storage income.
That is why Korea's storage bases are seen not as simple warehouses, but as strategic bases.
Five reasons why Korea is chosen as a candidate for an offshore stockpiling base
| Item | Korea's strengths | Why it matters |
|---|---|---|
| Location | Close to the large demand markets of Northeast Asia | Oil can be quickly sent to Korea, Japan, and China. |
| Storage capacity | 9 bases, total size of 1hundred million4,600ten thousand barrels | There is real physical space to receive and store foreign volumes. |
| Operating record | Joint stockpiling experience with Saudi Arabia, UAE, and Kuwait | It is not a first-time experiment, and trust is high because there are already contract cases. |
| System | Joint stockpiling system through Korea National Oil Corporation | The government and public corporation support it institutionally, so contract stability is high. |
| Risk management | Crude oil can be stored in a spread-out way outside Hormuz | It can reduce export problems when war or a blockade lasts long. |
Why does about 72% of Korea's crude oil come from the Middle East?
How did the Strait of Hormuz become the choke point of the world oil market?
It was originally an old trade route, but when the oil era began, it became a vital point of the world economy.
Stage 1: Trade crossroads
The Strait of Hormuz was originally a sea gateway connecting the Persian Gulf and the Indian Ocean. So its strategic location was already set even before oil was discovered.
Stage 2: Exit for Gulf oil-producing countries
In the 20th century, as crude oil exports from the Gulf region grew explosively, this narrow sea route became the main exit for Middle Eastern oil.
Stage 3: Memory of the tanker war
During the Iran-Iraq War in the 1980s, attacks on oil tankers continued, so people came to see strait risk as oil price risk.
Stage 4: Even the threat of blockade causes a shock
As seen during the renewed tension periods in 2011~2012, 2019, and 2025~2026, even without a real full blockade, just the threat can shake insurance costs, freight rates, and oil prices.
Oil passing through Hormuz actually increased
Even if it is risky, not everyone can take another route. So even during tension, the volume did not decrease much.
Is international joint stockpiling just a warehouse business that stores someone else's oil?
At first glance, it looks that way. Overseas oil-producing countries or oil companies store their crude oil in storage bases in Korea, and Korea receives warehouse rental fees. But in reality, this is closer to a model that combines storage business + emergency procurement contracts + energy diplomacy.
The key is speed. In a crisis, it is much faster to use supplies already inside Korea than to call in a new oil tanker from overseas. Depending on the contract, Korea can request priority purchase or priority release of the jointly stored supplies. It is not fully our oil, but in an emergency, it is within reach.
So it is better to see international joint stockpiling not as a system that replaces national stockpiling, but as a support tool that improves real emergency usefulness while costing less. Korea earns storage revenue, oil-producing countries gain a sales base in Asia, and in a crisis both sides have more options.
The supplies in international joint stockpiling are not owned by the Korean government.
Still, depending on the contract, priority purchase and release requests are possible, so it has been used as a real emergency response tool.
What is different between national stockpiling and international joint stockpiling?
| Comparison item | National stockpiling | International joint stockpiling |
|---|---|---|
| Ownership | Held by the Korean government | Held by overseas oil-producing countries and companies |
| Cost burden | Requires a large purchase budget | Korea mainly provides storage facilities, so the fiscal burden is relatively small |
| Control in a crisis | Strongest | Can request priority purchase and release within the contract scope |
| Supply speed | Fast because it is inside the country | Also fast because it is inside the country, but free use is limited |
| Additional effect | A pure security asset | Can also gain rental income and energy diplomacy effects |
How much stronger is Korea's stockpiling capacity than the IEA standard?
More important than the number of barrels is ‘how many days it can last.’ International comparisons also use this standard.
Why does the energy supply chain these days get shaken by just one narrow chokepoint?
It is not only unusual these days. But the past several decades of chasing efficiency have made the weakness even bigger.
Stage 1: The oil shock of the 1970s
This was the first time people deeply learned how much concentration in oil-producing countries and dependence on sea transport can shake the global economy.
Stage 2: Efficiency-centered globalization
In the 1990s and 2000s, supply chains crowded into the cheapest and fastest routes to cut costs. Efficiency went up, but detours became fewer.
Stage 3: Inventory reduction and real-time operation
In the 2010s, the method of reducing inventory and receiving things right on time spread widely. So even if just one chokepoint was blocked, the shock could spread right away.
Stage 4: Simultaneous spread of war and bottlenecks
Like the cases of Nord Stream, the Red Sea, and Hormuz, pipelines, straits, and sea corridors took turns shaking, so bottlenecks started to feel not like exceptions but like a constant.
Stage 5: New bottlenecks in the energy transition
From now on, not only oil straits but also the refining and processing stages of critical minerals are likely to become another 'narrow chokepoint.'
Where are the world's energy bottlenecks concentrated?
These are the oil transit volumes of major maritime chokepoints as of the first half of 2025. Even just looking at the numbers, you can feel how much flow is concentrated in a few routes.
If oil gets blocked, why do plastic, cars, and semiconductors also get shaken?
| Industry | Direct impact | Why do they shake together? |
|---|---|---|
| Gas station | Gasoline and diesel prices rise | Crude oil and refining costs spread directly to consumer prices. |
| Plastic | Naphtha, ethylene, and propylene prices rise | Petrochemicals are the starting materials for common plastics like plastic bags, containers, and packaging materials. |
| Cars | Parts, paint, tires, and logistics costs rise together | It is not only fuel that gets expensive. The costs of plastic and synthetic rubber also go up together. |
| Semiconductors | Chemical materials, utilities, and logistics costs rise | Even if they do not burn oil directly, production processes and transport are tied to energy and chemical materials. |
So now Korea is a consumer, but at the same time it is also aiming to become an energy hub
There is one interesting point here. Korea is a country that can hardly produce crude oil. But because of that weakness, the ability to store well and release quickly is actually becoming a strategic asset.
It is not only because Korea is a major power that Middle Eastern oil-producing countries look for Korean storage bases. Northeast Asian demand, ports, storage facilities, the joint stockpiling system, and already built-up cooperation experience are all there together, so it looks like a 'reliable hub to entrust.'
If we bring this down to our daily lives, the meaning becomes even clearer. If oil gets blocked, it is not only fuel costs that rise. Packaging materials, car parts, and even logistics costs for electronic products can shake too. So stockpiling bases and joint stockpiling may look like distant industrial policy, but in fact they are closer to a breakwater that protects everyday prices and manufacturing competitiveness.
Korea is not an oil-producing country, but it is becoming a hub for storage and procurement, so its strategic value is rising.
From now on, the key is not just having more reserves, but how quickly they can be used and rerouted in a crisis.
