1. Business Snapshot and Recent Developments

Industrial Bank of Korea ("IBK") is a government-related bank that institutionally performs South Korea's SME finance function. Looking at the issuer purely as a private commercial bank risks missing the central point of its credit profile. IBK is a banking group with deposits, loans, overseas branches, and subsidiaries, but under its founding statute, the IBK Act, it has a policy mandate to support the economic activities of SMEs, and is tied to government ownership, supervision, loss compensation, and a guarantee framework for certain bonds. For investors, the relevant questions are how stable IBK's stand-alone earnings, asset quality, and capital are; how much credit support can be expected from the South Korean government; and how far the legal protection differs by individual bond.

As of end-2025, the Korean government directly owned 59.50% of IBK's common shares, while Korea Development Bank held 7.20% and The Export-Import Bank of Korea held 1.84%. Government-related shareholders together accounted for approximately 68.5%. The IBK Act provides that the Chair and CEO is appointed by the President of Korea, that the annual business plan requires government approval, and that there are mechanisms for the issuance limit and government guarantee of SMIF bonds and an obligation for the government to provide funds to compensate losses. The Enforcement Decree requires at least 70% of total funds to be supplied to SMEs. These features support viewing IBK not merely as a listed bank, but as a policy finance institution.

At the same time, government-related status should not be read as an explicit guarantee of all bonds. Under the IBK Act, the government guarantee of principal and interest on SMIF bonds can be confirmed as a framework subject to National Assembly approval. However, whether ordinary foreign-currency senior notes, subordinated debt, AT1, or other individual securities benefit from any guarantee must be checked against the prospectus, pricing supplement, and subordination and loss-absorption provisions. This report analyses IBK's credit in three layers: 1) the stand-alone financial strength of the bank, 2) issuer credit after government support, and 3) legal protection and ranking by bond.

For FY2025, IBK maintained its scale and earnings base as a policy finance bank. Consolidated net income was KRW 2.719tn, up 2.4% year on year, while bank-only net income was KRW 2.386tn, down 1.7% year on year. Consolidated total assets were KRW 500.693tn, bank loans were KRW 315.623tn, Total Deposits as shown in the bank's IR Book were KRW 374.878tn, and equity capital was KRW 36.856tn. This Total Deposits figure is a management presentation that includes deposits, CDs/RPs and others, SMIF bonds, and trusts; it should be read separately from consolidated deposit liabilities in the financial statements. Profitability was ROA of 0.56%, ROE of 7.71%, and bank NIM of 1.58%. IBK is therefore less a high-profitability private-sector bank credit than a bank with a large SME lending base and policy role despite low lending spreads. At end-2025, the total capital ratio was 14.78%, the Tier 1 ratio was 13.26%, and the CET1 ratio was 11.48%. These provide a degree of headroom for an investment-grade bank, but CET1 remained below the bank's indicated 12.5% target.

1Q2026 is important as the latest disclosure after the annual report. Consolidated net income was KRW 753.4bn, down 7.5% year on year, while bank-only net income was KRW 666.3bn, down 12.4%. A KRW 91.1bn foreign-currency translation loss associated with the rise in KRW/USD was a drag on earnings, and this quarter alone is not sufficient evidence to conclude that underlying credit strength has deteriorated. Bank NIM was 1.60%, the NPL ratio was 1.28%, the total capital ratio was 14.93%, and the CET1 ratio was 11.51%. More important than the temporary decline in profit are SME loan growth, delinquency rates, provision coverage, and the pace of CET1 recovery.

The issuer profile and recent changes are as follows.

IBK's credit profile combines strong policy support expectations with concentration in SMEs, a cyclical borrower segment. In normal conditions, government links, scale, funding access, and indispensability in domestic SME finance support credit strength. In periods of deterioration in the Korean economy, interest rates, domestic demand, real estate, and manufacturing cycles, the same SME concentration can pressure stand-alone credit through delinquencies, NPLs, provisions, and RWA growth. In analysing IBK, it is necessary to give full weight to the downside support provided by government backing, while continuing to monitor how far the bank's own earnings and capital can absorb the cost of its policy mandate.

2. Industry Position and Franchise Strength

IBK's franchise should be assessed not only by deposit scale, but by the depth of its policy role in SME finance. South Korea's banking market includes major commercial banks, financial holding groups, government-related financial institutions, and policy finance institutions. Private-sector megabanks have broad revenue sources across retail deposits, mortgages, cards, asset management, and corporate banking. IBK, by contrast, has a statutory role focused on SME finance and is required not only to maximise earnings as a commercial bank, but also to continue providing policy-driven credit.

At end-2025, IBK's SME loans stood at KRW 261.9tn, accounting for 24.41% of South Korea's domestic SME loan market. By end-March 2026, SME loans had increased to KRW 264.244tn, up 0.9% from end-2025 and 4.2% year on year. IBK states that it supplied KRW 69tn of funding to SMEs in 2025, that its technology finance balance exceeded KRW 130tn, and that its market share was above 40%. These figures show that IBK is not simply a bank with a large volume of SME loans, but functions as part of South Korea's policy SME finance infrastructure.

This position is a clear credit strength. SME finance is prone to stress in downturns, but because it is linked to employment, supply chains, local economies, and technology industries, it increases the government's incentive to maintain IBK's credit standing.

At the same time, the strength in SME finance also constrains asset quality and profitability. SMEs generally have thinner liquidity buffers than large corporates and are more vulnerable to interest rates, raw material costs, labour costs, export demand, and construction and real estate cycles. As IBK's loan book grows, the policy rationale may remain sound, but RWA, provisioning, and collection costs at the bank level are more likely to increase. The NPL ratio remaining at 1.28% from 2025 to 1Q2026 is a stabilising factor, but the delinquency rate at end-March 2026 was 0.95% overall and 0.98% for SMEs, with higher readings in sectors such as construction, lodging and dining, real estate lease, and wholesale and retail.

Another franchise strength is IBK's funding access backed by its government link. The bank uses not only deposits but also SMIF bonds on a large scale. On the bank's disclosure basis at end-March 2026, deposits were KRW 129.379tn, core deposits were KRW 86.348tn, SMIF bonds were KRW 189.886tn, and Total Deposits including trusts were KRW 379.838tn. Total Deposits here is a funding-management presentation and is not pure deposit liabilities. For an ordinary private bank, heavy reliance on market funding would be viewed cautiously as a sign of a weaker deposit base. For IBK, however, SMIF bonds are an institutional funding tool for policy finance and are linked to the guarantee framework under the IBK Act, so they do not have the same meaning as wholesale funding dependence at a private bank.

However, having an institutional funding tool is not the same as eliminating liquidity risk. SMIF bonds are still affected by issuance markets, investor demand, interest rates, government guarantee approval, maturity concentration, and foreign-currency funding terms. For foreign-currency bonds in particular, Korean sovereign spreads, global bank spreads, investor demand for Korean financial institutions, and FX hedging costs determine refinancing conditions. IBK's franchise is strong, but funding stability should be assessed through both the institutional support framework and actual market liquidity.

Compared with major private-sector banks, IBK is likely to look weaker in earnings diversification and margins. The centre of credit is the SME-focused bank entity, and its policy mandate constrains earnings maximisation. IBK's investment thesis is therefore not that of a "high-profitability private bank", but the "credit stability of a policy bank with strong incorporation of Korean government support".

Compared with policy finance institutions, IBK shares strong support expectations with Korea Development Bank and The Export-Import Bank of Korea, but differs in combining a broader SME loan book with bank deposits and bond funding. KDB and KEXIM have stronger policy finance, industrial finance, and export-import finance characteristics, while IBK has a more pronounced commercial bank function as an SME bank. Therefore, IBK credit analysis requires close attention not only to the strength of government support, but also to ordinary banking indicators such as delinquencies, NPLs, NIM, provision coverage, and CET1.

3. Segment Assessment

IBK's business assessment needs to separate the bank's SME lending, household and retail lending, other corporate and public-sector lending, subsidiary earnings, and overseas operations. However, the credit centre of gravity clearly lies in the bank's SME portfolio. Of bank loans of KRW 317.881tn at end-March 2026, SME loans were KRW 264.244tn, or around 83%. Retail loans were KRW 43.131tn, and other loans were KRW 10.505tn. The quality of the SME loan book therefore determines IBK's earnings, capital, and provisioning.

By sector, manufacturing is the largest component of SME lending. As of end-December 2025, the SME loan portfolio comprised manufacturing at KRW 136.546tn, or 52.1%; wholesale and retail at KRW 41.595tn, or 15.9%; real estate lease at KRW 31.858tn, or 12.2%; construction at KRW 7.674tn, or 2.9%; lodging and dining at KRW 4.914tn, or 1.9%; and others at KRW 39.292tn, or 15.0%. The large manufacturing exposure is consistent with the policy objective of supporting South Korea's industrial base, but it also means exposure to export cycles, sector-level fluctuations in semiconductors, autos, machinery, chemicals and other industries, FX, and inventory adjustment.

This composition shows that IBK is particularly exposed to stress in SMEs, domestic demand, and manufacturing within the broader economy. At end-March 2026, sector delinquency rates were 0.86% for manufacturing, 1.64% for construction, 1.28% for real estate lease, 1.07% for wholesale and retail, and 1.40% for lodging and dining. Manufacturing has the largest balance but a delinquency rate below the overall average, while construction, real estate lease, and lodging and dining are higher. Credit deterioration in SME loans may first appear in delinquency rates, loan modifications, Stage 2, and lower provision coverage, before feeding through to the NPL ratio and credit costs.

The collateral and guarantee mix provides some support for the asset-quality view. At end-March 2026, the SME loan collateral split was 69.6% collateralised, 13.8% backed by guarantee certificates, and 16.6% unsecured. The high share of collateral and guarantees may help limit loss given default, but collateral values depend on real estate prices and liquidity, while guarantees depend on the guarantor's credit strength and payment process. This supports a lower ultimate loss rate after delinquency, but does not prevent delinquencies or NPLs from arising.

Household and retail lending is not the main credit driver for IBK. Retail loans were KRW 43.131tn at end-March 2026, much smaller than SME loans. However, South Korea's household debt, housing prices, and interest-rate trends can still affect the bank's overall asset quality and deposit behaviour.

Subsidiaries contribute to earnings diversification, but are not large enough to fundamentally change IBK's credit profile. Financial subsidiaries in securities, capital, insurance, and asset management supplement group earnings and provide scope for fee and investment income growth. However, the primary sources of credit risk remain lending and funding at the bank entity. Even if subsidiary earnings grow, a large increase in credit costs from SME lending would pressure group capital and earnings. This report has not extracted sufficient detail on subsidiary-level earnings, capital, and liquidity, so the assessment of non-interest income and group diversification remains supplementary to the bank analysis.

Overseas operations provide international funding and customer-support functions. In its 2025 consolidated financial statements, IBK had 598 branches and 31 depositary offices in Korea, and nine branches and two offices overseas. However, the core of the credit assessment is not overseas growth, but domestic SME asset quality and government support.

4. Financial Profile and Analysis

IBK's financial profile shows a degree of resilience as an investment-grade bank, but it does not have large excess margins in profitability or provisioning. Given its large SME loan book as a policy finance bank, its credit strength is supported not by high ROE but by the combination of stable earnings, manageable credit costs, adequate capital and liquidity, and government support expectations. From 2023 to 2025, total assets and loans expanded, and net income stayed broadly around KRW 2.7tn, but NIM declined and the NPL ratio rose compared with 2023.

On earnings, IBK's profits are not especially thick relative to its size. Bank NIM declined from 1.79% in 2023 to 1.70% in 2024 and 1.58% in 2025. This likely reflects the interest-rate environment, deposit competition, policy finance lending rates, and funding costs. At the bank-only level in 2025, Interest Income as shown in the IR Book was KRW 7.205tn, down 1.0% year on year, Non-Interest Income rose sharply to KRW 720.9bn, SG&A was KRW 3.025tn, and Net Provision was KRW 1.579tn. Improvement in non-interest income supported profit, and underlying spread income alone was not driving strong earnings growth.

From a credit perspective, the problem is less NIM compression in isolation than a scenario in which NIM compression and rising credit costs occur at the same time. In SME lending, higher rates may lift interest income, but they also increase borrowers' debt-servicing burden. In a falling-rate environment, borrower pressure may ease, but bank spreads tend to compress. As a policy finance bank, IBK has a role in maintaining credit supply, so it may need to absorb credit costs more than private-sector banks that can actively reduce risk in response to market conditions.

Asset quality is currently manageable, but this is stability that requires monitoring rather than a thick safety margin. At end-2025, the NPL ratio was 1.28%, the credit cost ratio was 0.47%, and LCR was 104.52%. The NPL coverage ratio declined from 107.7% at end-2025 to 105.2% at end-March 2026. These are not immediately dangerous levels for a bank, but coverage of only around one times NPLs is not especially thick if the economy weakens materially or collateral values decline. IBK is pursuing sales and write-offs and managing potential non-performing loans, but given the size of SME lending, comfort requires monitoring delinquency rates and Stage 2 trends.

The 1Q2026 data do not materially change the view from end-2025, but clarify the monitoring points. Bank loans increased to KRW 317.881tn and SME loans to KRW 264.244tn. The NPL ratio remained unchanged at 1.28%, the delinquency rate was 0.95% overall and 0.98% for SMEs, and the annualised credit cost ratio was 0.43%. Consolidated net income declined, but given the one-off factor of FX translation losses, this should not be read as an immediate decline in credit strength. However, a delinquency rate close to 1%, higher delinquencies in construction, real estate lease, and lodging and dining, and the decline in NPL coverage to 105.2% are key monitoring points for 2026.

On capital, IBK has a degree of regulatory capital headroom for a highly rated bank, but it is not overcapitalised. At end-2025, BIS capital was KRW 39.043tn, RWA was KRW 264.086tn, and CET1 capital was KRW 30.318tn. The CET1 ratio of 11.48% is a reasonable level within the banking system, but it is below IBK's indicated 12.5% target. Because the bank needs to build capital while expanding policy lending, retained earnings, RWA management, AT1 and Tier 2 issuance, and the nature of government support will be central to capital policy.

In summary, IBK has adequate earnings and capital even on a stand-alone bank basis, but its current high external ratings cannot be explained by stand-alone financials alone. NIM compression, SME concentration, lower provision coverage, and the CET1 shortfall versus target are clear constraints. At the same time, the bank is profitable, credit costs are manageable, and asset scale, government links, and market funding access are strong. IBK's credit strength should therefore be read by separating its investment-grade stand-alone bank resilience from its positioning in a higher rating category after government support.

5. Structural Considerations for Bondholders

The most important point in IBK bond investing is not to confuse the probability of government support with the legal protection of individual bonds. IBK is directly majority-owned by the Korean government and has a policy mandate, government approval framework, loss compensation, and SMIF bond guarantee framework under the IBK Act. This is very strong support for issuer credit. However, the ultimate claim held by bondholders differs according to issuer, guarantor, guarantee wording, subordination, loss absorption, payment suspension, governing law, and regulatory treatment.

The IBK Act contains several credit-relevant provisions. Article 1 sets out the purpose of promoting the independent economic activities of SMEs and improving their position in the national economy. Article 26 provides that the Chair and CEO is appointed by the President of Korea. Article 35 requires government approval for the annual business plan. Article 36-2 provides that IBK may issue SMIF bonds up to 20 times its paid-in capital. Article 36-5 allows for a government guarantee of principal and interest on IBK's SMIF bonds, subject to National Assembly approval. Article 43 requires the government to provide funds to compensate IBK if losses arise. Enforcement Decree 31 requires at least 70% of total funds to be supplied to SMEs. These article numbers and English summaries are based on the IBK Act summary in the 2025 annual report. This report has not independently verified the Korean statutory text, official English translation, practical use of Article 43, or the guarantee approval status for individual SMIF bonds.

These provisions show that IBK is deeply embedded in the government's policy objectives. Article 43's loss-compensation obligation is particularly strong from the perspective of issuer survival support. If IBK were to incur severe losses, the probability that the government would consider capital or funding support appears higher than for an ordinary private-sector bank. The same government link and policy importance explain why rating agencies place IBK in a high rating category.

However, Article 43 is not itself guarantee wording that gives investors a direct claim against the Korean government for principal and interest. A mechanism for the government to compensate the issuer's losses and a mechanism for the government to directly guarantee principal and interest on a specific bond are legally separate. In addition, the SMIF bond guarantee under Article 36-5 is subject to National Assembly approval. Therefore, it is risky to conclude that ordinary foreign-currency senior notes or subordinated securities are guaranteed merely because IBK is a government-related bank.

The bond-class view is as follows. This report has not fully reviewed individual securities' prospectuses, so guarantee, covenant, and subordination provisions remain items for additional checking before investment.

For ordinary foreign-currency senior notes, the difference between issuer credit and guarantee wording is especially important. IBK is a highly rated government-related bank, and the default probability of its senior debt is viewed as low. However, whether investors' recovery claim is against IBK or includes a direct claim against the Korean government is a separate issue.

For subordinated securities and AT1, government support expectations need to be read even more carefully. Even when a government supports the banking system, capital instruments are issued on the premise of loss absorption. Even for a policy bank such as IBK, AT1 and Tier 2 are not the same risk as senior debt. In AT1 in particular, coupon discretion, loss absorption, redemption approval, and regulatory non-viability triggers determine pricing and potential loss. Investment decisions should clearly distinguish the issuer credit from the capital nature of each security.

The structural conclusion is that IBK is an issuer with very strong government support expectations, but legal protection is not uniform across individual bonds. SMIF bonds, ordinary foreign-currency senior notes, Tier 2, and AT1 may all be issued under the INDKOR name, but their credit risk, recovery ranking, payment suspension risk, and the importance of guarantee verification differ. Assessing issuer credit alone is insufficient; individual security documentation needs to be checked before investment.

6. Capital Structure, Liquidity and Funding

IBK's funding structure sits between that of a conventional deposit-taking bank and a policy finance bank. It has a large deposit base, but also significant SMIF bonds and market funding. In the 2025 consolidated financial statements, deposit liabilities were KRW 168.163tn, borrowings were KRW 50.380tn, debentures were KRW 203.390tn, total liabilities were KRW 463.837tn, and total equity was KRW 36.856tn. By contrast, the bank's IR presentation showed, at end-March 2026, deposits of KRW 129.379tn, core deposits of KRW 86.348tn, SMIF bonds of KRW 189.886tn, trusts of KRW 57.304tn, and Total Deposits including trusts of KRW 379.838tn. Deposit liabilities in the financial statements and Total Deposits in the IR Book have different scopes, so a simple comparison should be avoided. Even so, it is clear that SMIF bonds and debentures are core funding sources.

Liquidity assessment needs to treat the institutional status of SMIF bonds correctly. SMIF bonds are an important funding tool for IBK to carry out SME finance and have an issuance limit and government guarantee framework under the IBK Act. This differs from a private-sector bank's heavy reliance on short-term market funding. As long as investors treat IBK's SMIF bonds as policy finance bonds with strong Korean government support, refinancing access should be relatively stable.

However, the high share of bond funding remains a monitoring point. In the 2025 consolidated financial statements, debentures were KRW 203.390tn, exceeding deposit liabilities. Because a large part of liabilities is refinanced in bond markets, IBK's funding terms are affected by Korea's sovereign rating, investor demand for the Korean banking sector, global rates, FX hedging costs, foreign-currency liquidity, and market stress. Even with strong government support expectations, market stress could widen new-issue spreads or raise foreign-currency funding costs, pressuring earnings.

The maturity table in the 2025 consolidated financial statements shows large short-term contractual cash outflows for won-denominated debt securities. Figures such as KRW 55.625tn within three months, KRW 43.913tn from three to six months, and KRW 59.725tn from six to 12 months are contractual cash-flow presentations and do not immediately imply a net liquidity shortfall. However, they show a funding structure in which large maturities are constantly rolling over. IBK's liquidity should therefore be assessed not only through a simple maturity table, but together with central bank and government-related borrowings, the SMIF bond market, liquid assets, LCR, and foreign-currency funding channels.

Borrowings also have a policy element. In the 2025 financial statements, won-denominated borrowings included borrowings from the Bank of Korea, policy-purpose borrowings from government-related entities such as the Korea SMEs and Startups Agency, and borrowings from KDB and others. This shows that IBK's funding does not rely solely on private markets, but it also requires checking the terms, maturities, use restrictions, and budget relationship of policy funds.

In the capital structure, the balance among CET1, AT1, and Tier 2 is important. At end-2025, CET1 capital was KRW 30.318tn, AT1 capital was KRW 4.710tn, and Tier 1 capital was KRW 35.029tn. The total capital ratio was 14.78%, while the CET1 ratio was 11.48%. There is a degree of regulatory headroom, but if RWA increases with policy lending expansion, CET1 will come under pressure. For IBK to maintain high ratings, it needs not only government support expectations, but also regulatory capital at levels that reassure the market as a bank.

In summary, IBK has strong market access as a government-related policy bank, but bond funding and the capital needs associated with policy lending expansion are significant. This is not a bank whose credit strength can be discussed on the deposit base alone; it is an issuer supported by the combination of SMIF bonds, government-related borrowings, foreign-currency bonds, regulatory capital, and Korean government support. Investors should monitor not only stand-alone LCR and CET1, but also maturity concentration, foreign-currency funding, capacity to issue capital instruments, and the confirmation status of SMIF bond guarantees.

7. Rating Agency View

IBK is highly rated by the major rating agencies. The ratings table in the 2025 annual report shows Moody's at Aa2, S&P at AA-, and Fitch at AA- throughout 2023, 2024, and 2025. This should be read as a level that strongly incorporates not only IBK's stand-alone bank credit, but also the probability of Korean government support, policy importance, government ownership, and the legal framework.

For Fitch, a Dodd-Frank rating information disclosure form dated 2025-10-22 can be confirmed for the affirmation of Industrial Bank of Korea at AA- with Stable Outlook. This report has not obtained the full Fitch rating report, so it does not cite the details of Fitch's rating rationale. However, the view that IBK's high rating depends materially on Korean government support and policy importance is consistent with IBK's ownership structure, the IBK Act, and the rating levels disclosed in the annual report.

For Moody's and S&P, this report has not sufficiently confirmed the full text of the latest IBK-specific rating reports from primary public pages as of 2026. Therefore, the latest rating action triggers and details of stand-alone credit assessment remain unverified. At the same time, the ratings table in the 2025 annual report shows that IBK maintained long-term ratings equivalent to the AA category from the three major rating agencies at least as of end-2025.

As sovereign-linked background, S&P affirmed Korea's long- and short-term foreign- and local-currency sovereign ratings at AA / A-1+ with Stable Outlook on 2026-04-29. The Korean Ministry of Economy and Finance also announced on 2026-02-12 that Moody's had affirmed Korea's sovereign rating at Aa2 with Stable Outlook. IBK's issuer rating should not be mechanically equated with the Korean sovereign, but because IBK's high ratings strongly incorporate government support, Korea's sovereign rating and outlook are important external conditions for assessing the ceiling and direction of issuer credit.

The point where the rating agency view and this report align is that IBK is not an ordinary private-sector bank, but a policy finance bank with strong incorporation of Korean government support. Even on a stand-alone bank basis, earnings, capital, and liquidity are maintained, and it is not a weak bank relying solely on government support.

At the same time, this report views differences in individual security risk as something that ratings alone may not fully capture. Even if the issuer rating is high, AT1 and Tier 2 carry loss absorption and subordination. Ordinary foreign-currency senior notes also require checking individual documents to confirm whether there is any explicit government guarantee. A high rating indicates low issuer default probability, but does not eliminate bond-specific payment suspension risk, recovery ranking, guarantee scope, or documentation risk.

Downgrade risk would increase with deterioration in Korean sovereign credit quality, a lower probability of government support, major changes to the IBK Act or policy framework, substantial deterioration in SME loans, sustained declines in capital ratios, or deterioration in liquidity and market access. Some fluctuation in the stand-alone NPL ratio alone is unlikely to immediately change the high rating, but a simultaneous increase in SME delinquencies, decline in NPL coverage, and decline in CET1 would be material as a deterioration in stand-alone credit.

8. Credit Positioning

IBK's credit positioning needs to distinguish comparison with policy finance and government-related issuers such as KDB, KEXIM, and KHFC from comparison with major private-sector banks such as KB Kookmin, Shinhan, Hana, and Woori. IBK has government support expectations closer to the former, while being assessed through the same banking metrics for asset quality, capital, and liquidity as the latter.

Relative to policy finance issuers, IBK is very strongly positioned. Direct majority government ownership and the IBK Act framework clarify the probability of support. The policy mandate of SME finance becomes more important during economic deterioration, making it easier to recognise high support expectations among government-related issuers.

However, compared with KDB and KEXIM, IBK has a stronger bank-portfolio profile. Delinquencies, NPLs, credit costs, and collateral values in SME lending appear as day-to-day credit indicators. IBK is therefore better positioned as a government-supported bank credit rather than a simple quasi-sovereign bond.

Relative to major private-sector banks, IBK's strengths are government support and policy importance, while its weaknesses are profitability, business diversification, and SME concentration. FY2025 ROE of 7.71% and NIM of 1.58% indicate that IBK should be assessed as a policy bank, not a high-profitability bank.

Relative value assessment requires individual bond spreads, tenor, currency, guarantee confirmation, liquidity, rating differences, and security class. This report has not checked live spreads, OAS, or individual bond prices, and therefore does not make a rich-or-cheap assessment. Structurally, SMIF bonds, ordinary foreign-currency senior notes, Tier 2, and AT1 need to be separated, with guarantee, ranking, and loss absorption checked.

When using IBK in a portfolio, it is necessary to clarify whether it is managed within the Korean sovereign/quasi-sovereign bucket, the Korean bank sector bucket, or the Asian high-grade financials bucket. Credit risk is materially linked to government support, but short-term market valuation is also affected by the banking sector, foreign-currency funding, and AT1/Tier 2 markets.

9. Key Credit Strengths and Constraints

IBK's largest credit strength is its institutional link with the Korean government. Direct majority government ownership, KDB and KEXIM participation as shareholders, CEO appointment, business plan approval, loss compensation, and the SMIF bond guarantee framework under the IBK Act are support factors that ordinary private-sector banks do not have.

The second strength is its dominant business base in SME finance. SME loans were KRW 261.9tn at end-2025, with a domestic market share of 24.41%, and expanded to KRW 264.2tn at end-March 2026. This position supports both the earnings base and policy importance.

The third strength is that earnings, capital, and liquidity are currently in a manageable range. Consolidated net income in 2025 was KRW 2.719tn, the total capital ratio at end-March 2026 was 14.93%, and the CET1 ratio was 11.51%. IBK is not an issuer whose weak stand-alone bank condition is being covered only by government support.

The largest constraint is SME concentration. SME loans account for most of bank loans and include cyclical sectors such as manufacturing, wholesale and retail, real estate lease, construction, and lodging and dining. If the Korean economy, interest rates, real estate, domestic demand, and exports weaken at the same time, delinquencies, NPLs, and credit costs are likely to rise.

The second constraint is declining profitability. Bank NIM declined from 1.79% in 2023 to 1.58% in 2025, while ROA was 0.56% and ROE was 7.71%. Lower profitability limits the scope to absorb credit costs and capital build-up through internal earnings.

The third constraint is that provision coverage and capital headroom are not overwhelmingly thick. NPL coverage declined from 107.7% at end-2025 to 105.2% at end-March 2026, while the CET1 ratio is around 11.5% and below IBK's 12.5% target.

The fourth constraint is bond-funding dependence and the complexity of individual security structures. SMIF bonds and debentures are core funding sources for IBK, and even with institutional support they are affected by market conditions, maturity concentration, and foreign-currency funding terms. In addition, SMIF bonds, ordinary foreign-currency senior notes, Tier 2, and AT1 have different risks; making an investment decision based only on the issuer name may create a mismatch between expected protection and the actual legal claim.

10. Downside Scenarios and Monitoring Triggers

A realistic downside scenario for IBK would be credit deterioration in the Korean SME sector feeding sequentially into delinquency rates, NPLs, provisions, capital ratios, and market funding conditions. The first signs are likely to appear in sectors with higher delinquency rates as of end-March 2026, such as construction, real estate lease, lodging and dining, and wholesale and retail. If the overall SME delinquency rate rises above 1% and continues increasing, the NPL ratio settles above 1.5%, and NPL coverage falls below 100%, pressure on stand-alone credit would become clear.

The second downside scenario is policy-driven loan growth running ahead of capital. If the government strengthens funding supply to SMEs during an economic downturn, IBK's policy importance would rise, but RWA and credit costs could also increase. If loans and RWA grow while profits do not, the CET1 ratio falls below 11%, and the gap versus the 12.5% target widens, market valuation of capital instruments and senior notes would likely come under pressure even with government support expectations.

The third downside scenario is a deterioration in the Korean sovereign or in the assessment of government support. IBK's high rating depends heavily on government support, so deterioration in Korea's sovereign rating, government fiscal capacity, or the market view of the IBK Act and government support framework could directly affect issuer ratings.

The fourth downside scenario is an abrupt change in market funding conditions. If investor demand for SMIF bonds or foreign-currency senior notes weakens and observable new-issue terms or secondary-market indicators deteriorate materially, refinancing costs and NIM would come under pressure. Institutional support makes outright loss of refinancing access unlikely, but higher funding costs would affect earnings and capital formation.

The key monitoring items are as follows.

In upcoming regular disclosures, the priority should be to check the 2Q2026 and subsequent IR Books, half-year financials, NPL coverage, sector delinquency rates, CET1, and SMIF bond issuance status. In particular, it is necessary to distinguish whether the 1Q2026 earnings decline ends as an FX-translation-loss issue, or whether it broadens into NIM and credit costs. The annual credit view should change based more on the direction of asset quality and capital than on a single quarter's profit.

11. Credit View and Monitoring Focus

IBK's current credit standing is constrained on a stand-alone bank basis by SME concentration, but it is positioned in a high investment-grade category through strong incorporation of Korean government support. The near-term direction is stable to somewhat cautious. The focus is less the 1Q2026 earnings decline itself and more the need to continue monitoring SME delinquency rates, NPL coverage, and slow improvement in CET1. A rapid deterioration in level or direction does not appear highly probable at this point, but if a weaker Korean economy, asset-quality deterioration, and changes in the sovereign link coincide, market valuation of individual bonds could react before issuer ratings.

The support for issuer credit is clear. The Korean government directly owns 59.50% of IBK, with KDB and KEXIM also as shareholders. The IBK Act sets out the policy objective of SME finance, government appointment of the CEO, business plan approval, SMIF bond issuance, the government guarantee framework, and the loss-compensation obligation. A market share of more than 24% in SME finance supports the expectation of government support through institutional indispensability.

At the same time, stand-alone bank credit cannot be ignored. ROE was 7.71% in 2025 and bank NIM was 1.58%, so profitability is not high. The NPL ratio of 1.28% is manageable, but NPL coverage had declined to 105.2% by end-March 2026. The CET1 ratio was 11.51%, below the 12.5% target. These are not immediately dangerous figures for a highly rated government-related bank, but they define the ceiling for stand-alone credit strength. IBK's strength lies not in self-contained credit strength generated by high profitability, but in the combination of policy support and manageable bank financials.

For senior bond investors, issuer default probability is viewed as low. Government support, ratings, policy importance, and funding access are strong, and as of 1Q2026 there was no abrupt change in asset quality or capital. However, ordinary foreign-currency senior notes should not be treated as identical to government-guaranteed bonds. Whether a guarantee is explicit, whether the bond is a SMIF bond or ordinary senior note, and the governing law, guarantee scope, cross default, and negative pledge provisions need to be checked in individual security documents.

For AT1 and Tier 2, loss absorption and payment suspension risk should be assessed independently of the strength of issuer credit. Government support expectations for IBK provide some background support to capital instruments, but capital instruments are issued to absorb losses before senior debt. With CET1 below the target, the price of capital instruments is more sensitive to regulatory capital headroom, earnings, dividend and coupon restrictions, and call probability than to the issuer rating alone.

For future monitoring, from 2Q2026 onward it will be necessary to check: 1) whether SME loan growth is accelerating for policy reasons; 2) whether delinquency and NPL ratios are rising; 3) whether NPL coverage falls below 100%; 4) whether the CET1 ratio moves toward the 12.5% target; and 5) if market data are available, whether SMIF bond and foreign-currency senior new-issue terms are deteriorating relative to the Korean sovereign. Improving the credit view on IBK would require NIM bottoming, stable credit costs, CET1 build-up, and recovery in NPL coverage. Conversely, if rising SME delinquencies, lower CET1, and lower NPL coverage proceed at the same time, individual securities would need to be reassessed even with government support expectations.

12. Short Summary & Conclusion

Industrial Bank of Korea is a policy finance bank directly majority-owned by the Korean government and institutionally responsible for SME finance. Issuer credit is strongly supported by government support expectations and indispensability in domestic SME finance, while stand-alone constraints include SME concentration, low NIM, lower NPL coverage, and the shortfall versus the CET1 target. SMIF bonds, ordinary foreign-currency senior notes, Tier 2, and AT1 may all carry the same INDKOR name, but guarantee, subordination, and loss absorption differ; therefore, reviewing individual security documentation is a prerequisite for investment decisions.
