Issuer Overview

• The Korea Development Bank ("KDB") is a statutory Korean policy-finance institution established in 1954 under The Korea Development Bank Act.
• KDB is 100% owned by the Korean government according to the 2025 KDB IR Presentation.
• KDB's role includes industrial development finance, infrastructure and regional development, financial market stabilisation, corporate restructuring, sustainable growth, advanced strategic industries, and related policy-finance functions.
• KDB should be analysed as Korea's national development finance institution, not as an ordinary commercial bank and not as the Republic of Korea itself.

Core Credit View

• KDB's support-inclusive credit strength is very close to the Korean sovereign because of full government ownership, statutory policy role, government supervision, Article 32 loss-compensation support, capital injections, and ratings aligned with Korea's sovereign ratings in KDB's IR materials.
• Ordinary KDB senior notes are KDB obligations unless the relevant documents explicitly state a Korean government guarantee. The January 2026 SEC notes are a clear example of ordinary KDB notes with no government guarantee on principal and interest.
• Article 32 is an issuer-level annual net-loss deficiency support framework. It should not be described as an unconditional payment-date guarantee for every bond.
• The latest current-report financial basis is KDB's 2025 IR Presentation through 1H25 and SEC Form 424B2 unaudited selected separate K-IFRS data through 9M25. FY2025 audited annual report was not confirmed in the current report.

Business and Franchise View

• KDB's franchise strength comes from its difficult-to-substitute role as a financial execution arm of Korean industrial policy, restructuring, market stabilisation, infrastructure finance, and growth-industry support.
• KDB's policy mandate can expand during stress or strategic-industry investment cycles, which increases government support incentives but can also increase credit risk, capital needs, and balance-sheet burden.
• High-Tech Strategic Industry Fund and National Growth Fund themes are important current policy contexts. They increase KDB's strategic relevance and require monitoring of capital, risk sharing, and any government-guaranteed fund-bond structure.

Capital Structure and Structural Points

• KDB Act Article 32 provides for annual net losses to be covered first by reserves and then by the government if reserves are insufficient.
• KDB Act Article 19 and Article 26 allow government guarantees for certain foreign-currency liabilities and Industrial Finance Bonds with prior National Assembly approval. These provisions must be checked instrument by instrument and are not automatic guarantees for all KDB debt.
• KDB's authorised capital ceiling was described in the January 2026 SEC Form 424B2 as increased from KRW30 trillion to KRW45 trillion following the 2025 KDB Act amendment and December 2025 articles-of-incorporation amendment.
• Capital securities, Tier 2 instruments, government-guaranteed bonds, Industrial Finance Bonds, ordinary senior notes, sustainable/green/social bonds, and policy-fund bonds require separate legal and structural review.

Liquidity and Funding View

• KDB relies heavily on market-based funding, including debentures, Industrial Finance Bonds, domestic issuance, USD/EUR benchmark issuance, private placements, and bank loans.
• The 2024-2025 foreign-currency funding track record and January 2026 SEC-registered issuance confirm strong international market access at the time of the current report.
• Liquidity and spreads remain sensitive to Korea sovereign conditions, USD/EUR investor demand, hedging costs, LCR and foreign-currency liquidity management, and investor confidence in government support.

Credit Strengths

• 100% Korean government ownership and statutory policy-finance mandate.
• Article 32 annual net-loss support framework, FSC oversight, government appointment and approval channels, and capital-injection capacity.
• International ratings aligned with Korean sovereign ratings in KDB's IR materials.
• Large and proven domestic and international funding platform.
• Latest disclosed capital and asset-quality indicators used in the current report did not show material weakening, though FY2025 audited figures were not confirmed.

Credit Weaknesses

• Ordinary KDB notes are not automatically direct Korean government-guaranteed obligations.
• Policy finance, corporate restructuring, advanced strategic industries, guarantees, and market-stabilisation roles can create asset-quality, capital, and earnings volatility.
• KDB depends heavily on domestic and foreign-currency market funding.
• FY2025 audited annual report, latest full rating-agency reports, amended KDB Act English text, and bond-by-bond terms were not fully confirmed in the current report.

Rating Watchpoints

• Korea sovereign ratings and outlooks.
• Government ownership, Article 32 interpretation, capital injections, FSC supervision, and policy-finance mandate.
• BIS and Tier 1 ratios, NPL ratio, coverage, credit costs, guarantees, derivative effects, and single-name restructuring exposures.
• USD/EUR/KRW issuance conditions, hedge costs, foreign-currency liquidity, and investor demand.
• Instrument-specific guarantee status, ranking, capital nature, governing law, covenants, and tax provisions.

Ongoing Follow-Up Items

• Monitor Korea sovereign ratings, outlooks, fiscal and external conditions, and Korean SSA/quasi-sovereign spread sentiment because KDB's support-inclusive credit is tightly linked to the sovereign.
• Monitor government ownership, Article 32 interpretation, KDB Act amendments, FSC oversight, capital injections, authorised capital usage, and any change in KDB's statutory mandate.
• Track policy-driven exposure growth in corporate restructuring, market stabilisation, semiconductors, batteries, AI, robotics, bio, defense, infrastructure, high-tech strategic industries, and National Growth Fund activity.
• Monitor debentures, Industrial Finance Bonds, foreign-currency funding, USD/EUR benchmark issuance, private placements, bank loans, LCR, hedging costs, foreign-currency liquidity, and investor demand.
• Use the SEC 424B2 9M25 selected financial data when discussing the current interim financial position until FY2025 audited accounts are available.

Unresolved Issues and Items to Check Next Time

• Confirm FY2025 audited Annual Report and update financial statements, NPL, coverage, capital, guarantees, derivatives, maturity ladder, funding tables, and notes to the accounts.
• Obtain latest full Moody's, S&P, and Fitch reports, especially support assumptions, standalone assessment, government-related entity treatment, and downgrade triggers.
• Obtain the full English text of the amended KDB Act after the September 2025 amendment if available, and update authorised capital and High-Tech Strategic Industry Fund legal wording.
• Update selected substandard-or-below exposure data, especially HMM, shipbuilding names, GM Korea, and Taeyoung E&C, when new SEC or annual report data is published.
• For any bond-specific recommendation, review the actual pricing supplement and confirm whether the bond is ordinary KDB, government-guaranteed, Industrial Finance Bond, sustainable/green/social, policy-fund related, or capital securities.
• Track live spreads versus Republic of Korea, KEXIM, IBK, KHFC, Korean commercial banks, Korean GREs, and SSA peers before making a relative-value call.

Analytical Cautions

• Treat KDB as Korea's statutory policy bank and national development finance institution, not as an ordinary commercial bank and not as the Republic of Korea itself.
• Always separate four support and security concepts: ordinary KDB senior notes, Article 32 annual loss support, Article 19/26 government-guarantee possibilities with National Assembly approval, and capital securities/Tier 2 instruments.
• Do not stop at 1H25 if the SEC 424B2 9M25 data are relevant and available in the workspace.
• NPL ratio alone is not enough for policy-finance risk. Analyse guarantees, investments, restructuring exposures, strategic-industry policy risk, derivatives, and funding conditions.
• Net income can include investment gains, impairment reversals, derivative effects, and credit-cost swings; do not treat it as a simple recurring earnings indicator.

Report Wording Cautions

• Do not write that ordinary KDB bonds are Korean government obligations unless the final terms explicitly state a government guarantee.
• Describe Article 32 as annual net-loss deficiency support after reserves, not as an unconditional and irrevocable payment guarantee for every bond.
• State clearly when figures come from unaudited 9M25 SEC selected data, 1H25 IR presentation data, or audited annual reports.
• When mentioning the KRW45 trillion authorised capital ceiling, cite the January 2026 SEC Form 424B2 unless a current amended English KDB Act text has been obtained.
• Avoid relative-value language without live spread and target-bond term confirmation.

Follow-Up on Management Strategy, Investment Plans, and Financial Policy

• Track the implementation of the High-Tech Strategic Industry Fund and National Growth Fund, including capital support, risk sharing, guarantee structure, and actual exposure growth.
• Monitor government capital-injection policy and whether capital keeps pace with policy-finance expansion and risk-weighted assets.
• Check whether new policy-fund bonds are government-guaranteed, ordinary KDB obligations, or a separate structure.

Items to Check for Ratings and Bond Investors

• Latest rating-agency reports and Korea sovereign rating actions.
• Bond-by-bond government guarantee status, ranking, capital nature, governing law, covenant, events of default, tax gross-up, and use of proceeds.
• USD/EUR/KRW maturity profile, hedge position, funding costs, LCR, and foreign-currency liquidity.
• Updated asset-quality indicators, large substandard-or-below exposures, guarantees, derivatives, and capital ratios.
