Hormuz Reblocked Despite Truce, Korea Faces 2–3 Week Supply Gap

U.S.-Iran Truce Leaves Risks for South Korea’s Supply Chain

The United States and Iran agreed on the 7th local time to a two-week truce and the opening of the Strait of Hormuz, but the number Korean investors should focus on is not the length of the truce—it is South Korea’s 67.1% dependence on Middle Eastern crude imports. The real implication is that merely halting hostilities does not eliminate raw-material procurement risks for domestic industries such as refining, petrochemicals, automobiles and steel.

The Strait of Hormuz crisis is a supply-chain issue in which the U.S. maritime blockade of Iran and Iran’s policy of controlling the strait combine to undermine the continuity of shipping operations. What has been confirmed is a temporary truce. What remains unconfirmed is a final agreement and the durability of shipping safety.

Blockade Standoff Continues Beyond Two-Week Truce

Seoul Economic Daily reported that the United States and Iran agreed on the 7th local time to a two-week truce and the opening of the Strait of Hormuz. The truce provides time for cargo movements to resume, but it is not an agreement that ends the conflict over control of the sea lanes.

According to TV Chosun, the United States said it would maintain its maritime blockade of Iran until an agreement is reached. Iran’s military also announced that it would resume control of the Strait of Hormuz. Donald Trump claimed that Iran had agreed not to close the strait again, but Ghalibaf countered, “We on the ground hold the real key.”

The scale of the operation is also evident in the number of vessels involved. U.S. Central Command said 21 vessels have turned back toward Iran at the direction of the U.S. military since the counter-blockade began. Iran’s Esmaeil Baghaei said Tehran would take corresponding measures if the United States maintains the blockade.

Iran’s Seven Conditions Have Yet to Be Disclosed

According to The Hankyoreh, Iran has set seven conditions for opening the Strait of Hormuz. The specific conditions are not included in the FACT_SHEET. There is therefore no basis yet for determining whether the conditions for opening the strait have been met or whether shipping operations can continue.

What markets can already price in is the direction represented by the truce. The variables that remain difficult to fully price are the sequence in which both sides actually lift their blockade measures and whether a final agreement is reached. If the U.S. blockade continues, the standoff—in which Iran threatens to resume control of the strait—will return.

Nuclear Talks Are the Next Hurdle for Reopening Hormuz

According to JoongAng Ilbo, Donald Trump said on the 6th local time that an agreement with Iran was highly likely and that the United States would take possession of enriched uranium. Whether the uranium will actually be removed has not been confirmed. Esmaeil Baghaei said Iran would review the U.S. proposal and convey its position to Pakistan.

No agreement has been reached on the duration of the enrichment moratorium either. Donald Trump has demanded more than 20 years, while Iran has proposed five years, and Axios reported that the United States and Iran are discussing a period of 12 to 15 years. If a memorandum of understanding is signed first, the proposed negotiating period would be 30 days, but neither a final agreement nor its full terms have been disclosed.

Donald Trump also rejected the idea of allowing Iran to conduct low-level enrichment of up to 3.67% after the suspension period ends. Narrowing the gap over nuclear terms could make the truce and the opening of the strait more durable. If talks break down, the tit-for-tat cycle of a maritime blockade and renewed control of the strait will return to the forefront.

South Korean Industry Faces Exposure Beyond Crude Oil

At the time of publication, the Korea Institute for Industrial Economics and Trade estimated South Korea’s dependence on Middle Eastern imports at 67.1% for crude oil, 46.3% for aluminum ingots and alloys, 44.7% for naphtha and 42.9% for anhydrous ammonia. The figures were 33.0% for LNG, 31.1% for polyethylene, 30.6% for petroleum coke and 24.3% for helium. This means the risk extends beyond energy alone.

• Refining and petrochemicals: Continuity in crude oil and naphtha procurement is critical. Any reduction in feedstock supplies would constrain production processes first.
• Automobiles and steel: Heavy dependence on the Middle East for aluminum ingots and alloys, anhydrous ammonia and petroleum coke remains a supply-chain concern.
• Semiconductors: Helium procurement risks cannot be assessed separately from whether the strait remains open. Investors need to verify that actual supply inflows continue, rather than relying on the declaration of a truce.

Lee Joon, head of the Strategic Industry Research Center at the Korea Institute for Industrial Economics and Trade, said South Korea would inevitably face a raw-material supply gap over the next two to three weeks because shipments had been unable to enter the country for nearly a month. How long the actual gap will persist remains unconfirmed.

Hormuz Checkpoints for Investors

• Maritime measures: Watch whether the United States maintains its blockade until an agreement is reached and whether Iran’s military actually resumes control of the strait.
• Conditions for opening: Check whether the specific details of Iran’s seven conditions are disclosed and whether they are met.
• Nuclear agreement: Track separately the duration of the enrichment moratorium, the transfer of enriched uranium to the United States and whether a memorandum of understanding is signed.
• Domestic supplies: If the expected raw-material supply gap over the next two to three weeks begins to ease, uncertainty surrounding essential production inputs for industries such as refining and petrochemicals will also decline.

Keeping Hormuz Open Is More Important Than the Truce

In the optimistic scenario, the United States and Iran would jointly ease the maritime blockade and control of the strait while narrowing their differences in nuclear negotiations. Under this path, the two-week truce would serve as a bridge to a final agreement.

The trigger for the downside scenario would be either side maintaining its blockade measures. If Iran takes corresponding action or the United States intensifies pressure, risks to shipping safety and South Korea’s raw-material procurement would rise again. The next indicators to watch are not declarations, but whether the Strait of Hormuz remains open, the flow of vessels turning back and the recovery of South Korea’s raw-material supplies.
