South Korea — K-SURE US$1bn guarantee for LG Chem's Tennessee cathode material plant (first tranche under US-Korea tariff-deal investment fund)

Mechanism

K-SURE is South Korea's state export-credit agency (under the Ministry of Trade, Industry and Energy). Rather than a direct grant, the support here is a sovereign guarantee that lets LG Chem borrow project-finance debt from international banks (Crédit Agricole CIB and BNP Paribas acted as ECA coordinators per deal-advisory reporting) at rates it could not access unguaranteed. K-SURE's own statement frames the guarantee as the first investment support issued after Seoul and Washington concluded their July 2025 tariff negotiation, under which Korea committed to a large bilateral investment fund for the US market — this guarantee is being positioned as an early tranche of that broader commitment rather than a standalone decision.

Tennessee already hosts an LG Energy Solution/GM battery joint venture, so the cathode plant plugs directly into an existing Korean-anchored EV battery cluster in the state.

Downstream implications

• Reduces LG Chem's/Korea's cathode-material exposure to Chinese

precursor/cathode supply by localizing a large NCMA line inside the US, ahead of IRA/FEOC-style sourcing requirements.

• Establishes a template: expect further K-SURE-guaranteed tranches for other

Korean firms (battery, shipbuilding, semiconductors) investing in the US under the same bilateral fund commitment — watch for the formal special act/ MOU implementing legislation (see 2026-03-12-south-korea-us-strategic-investment-special-act and 2025-12-04-us-korea-strategic-trade-investment-deal) to retroactively bracket this as an early disbursement.

• Adds to the western-ex-China cathode/CAM capacity build-out tracked

alongside EU Innovation Fund battery-materials grants (Finland Easpring, Sweden Novo Energy, France ACC/Verkor).

Open questions

• Exact KRW-denominated guarantee terms (tenor, guarantee fee, lender

syndicate) were not disclosed in the K-SURE release.

• Whether this guarantee is formally counted against the US$350bn Korea-US

strategic investment cap set by the March 2026 Special Act, or predates and sits outside that facility's accounting.
