South Korea's Ministry of Trade, Industry and Resources and SK hynix signed an agreement on 19 October 2026 at Yongin that makes the state's export insurer the guarantor of the memory maker's supply base. SK hynix and four banks (KB Kookmin, Shinhan, Woori and Hana) contribute ₩100 billion, and the Korea Trade Insurance Corporation (K-SURE) guarantees up to ₩2 trillion of loans, twenty times the contribution, to semiconductor materials, parts and equipment suppliers that SK hynix recommends. Borrowers get interest cuts of up to 2.5 percentage points, and guarantee terms extend from one year to three. The program is signed; the ₩2 trillion is a guarantee ceiling, not disbursed lending.
The ministry calls it the largest single-company program of its kind, and most of the coverage led there. Size is the less interesting fact. The scheme belongs to the export supply-chain strengthening guarantee that Seoul launched in August 2025, which the ministry says has already raised ₩2.4 trillion for autos, shipbuilding and steel. What is new is the layer. The guarantee is aimed at the toolchain beneath the fab, the same dependency the desk read in August when Seoul announced a ₩5 trillion national fund for everything around the wafer. Then the instrument was an announced fund with no vehicle described. Now it is a signed state guarantee, which draws on the public balance sheet only when a supplier fails to repay.
Two details complicate the arithmetic. The ministry's release gives the contribution as ₩100 billion, but its event schedule gives the total contribution as ₩133 billion, a gap the release does not explain. And the ministry says it plans to lift chip-sector support to at least ₩5 trillion and extend the scheme to defense, nuclear and biotech, for about ₩10 trillion in total by year-end. Both larger figures are targets. Only the ₩2 trillion program is signed.
The plumbing tells the strategy. The state's balance sheet supplies the multiple, the banks supply the loans, and the selection sits with SK hynix: eligibility runs through the company's recommendation before K-SURE's own guarantee review. That puts a national champion's procurement judgment at the front of a sovereign credit decision. It is efficient, because the buyer knows which suppliers it needs. It also means the state is underwriting one company's view of its own supply chain, and the release publishes no criteria for that recommendation.
The sovereign thread is explicit. An export-credit agency, built to insure what Korea sells abroad, is guaranteeing domestic loans to the suppliers of a domestic fab. The ministry sets the maximum guarantee limit 50 percent above other industries', citing the sector's weight: chips made up 42 percent of Korean exports through September.
Seoul has lent its credit rating to the toolchain and let the customer choose the borrowers, and in a guarantee scheme the chooser is where the risk is really priced.
