1. Purpose and Treatment

This report is a supplementary organisation of the discussion dated 2026-05-29, cross-checked against Maybank’s existing issuer summary. It is not intended to provide a final investment conclusion, a definitive rating outlook view, or recognition of new facts.

The discussion repeatedly focused on what would serve as the first warning signal for Maybank’s credit profile under stress. The central issues were: the possibility that higher deposit retention costs could matter before sudden deposit outflows; the possibility that ROAR30 investments and the maintenance of high dividends could weaken internal capital generation; the possibility that a simultaneous ASEAN-wide stress scenario should be weighted more heavily than Indonesia on a standalone basis; the distinction between support expectations from D-SIB status and loss-absorption risk in capital instruments; and the likely sequence of deterioration in SME, working-capital, commercial real estate, and mortgage exposures under domestic asset-quality stress.

The sections below distinguish between points already confirmed in the existing report, arguments and hypotheses raised in the discussion, and unresolved items. The discussion includes answers based on additional web checks, but those points have not been re-verified against primary sources at the time of preparing this report. Therefore, figures or measures that are not included in the existing issuer summary are treated, in principle, as “discussion-based assertions” or “items for additional confirmation”.

2. Confirmed Baseline from the Existing Report

The existing Maybank issuer summary frames the bank not as a “high-growth bank”, but as a defensively positioned bank credit supported by a deep domestic deposit franchise in Malaysia, ASEAN connectivity, Islamic finance, and capital and liquidity buffers. For FY2025, the confirmed metrics are net profit of RM10.51bn, ROE of 11.7%, CET1 ratio of 15.13%, total capital ratio of 19.05%, LCR of 138.2%, NSFR of 116.6%, CASA ratio of 40.5%, NIM of 2.05%, gross impaired loans ratio of 1.28%, loan loss coverage of 106.7%, and net credit charge-off rate of 8bps.

On this basis, Maybank starts from a position of strength. However, the existing report also retains several monitoring points: a modest increase in the GIL ratio, declining coverage, renewed NIM pressure, credit cost normalisation, deterioration in Indonesia or the corporate book, and loss-absorption risk in subordinated capital instruments. The current discussion can be viewed as a decomposition of these existing monitoring points into more portfolio-management-oriented early warnings.

3. Read-Through from the Discussion

First, the discussion suggested that funding stress at Maybank could emerge first through higher deposit retention costs and NIM pressure, rather than immediately through weaker liquidity ratios. The existing report also notes that deterioration in the deposit franchise often appears not as funding outflows, but as higher deposit costs, a higher term-deposit mix, and a lower CASA ratio. Therefore, NIM, CASA, deposit mix, and foreign-currency funding costs need to be monitored alongside LCR and NSFR.

Second, with regard to ROAR30 investments and the relatively high dividend payout ratio, the discussion raised the hypothesis that, while they may improve efficiency and earnings power over the long term, they could weaken internal capital generation in a short-term downside scenario through front-loaded expenses and insufficient capital retention. The discussion suggested that technology, data, and AI-related investments should be assessed together with CIR, PPOP, post-dividend CET1, RWA growth, and upside risk to NCC. However, the annual investment allocation under ROAR30, the split between expensed and capitalised items, and dividend flexibility under stress remain unconfirmed.

Third, for overseas operations, the discussion considered that an ASEAN-wide stress scenario in which the credit cycles of Malaysia, Singapore, and Indonesia deteriorate simultaneously may be more relevant for group credit cost and internal capital generation than an asset-quality deterioration in Indonesia alone. Regional diversification is normally a stabilising factor, but if real estate, SME, and corporate exposures deteriorate simultaneously across multiple markets, the diversification benefit could weaken and the same structure could become a transmission channel through which credit costs rise on an aggregated basis.

Fourth, the discussion repeatedly drew a distinction between D-SIB status as a potential credit support for senior debt, deposits, and short-term liquidity, and any assumption that the same support protects AT1 or Tier 2 instruments. D-SIB status can support market confidence in the avoidance of a disorderly failure, but capital instruments are loss-absorbing instruments. Key monitoring points therefore include a decline in the CET1 buffer, BNM’s stance on capital conservation, deterioration in the sovereign outlook, and spread divergence between AT1 / Tier 2 instruments and senior debt.

Fifth, on domestic asset quality under macro deterioration, the discussion raised the hypothesis that SME, working-capital, Business Banking, commercial real estate, and construction-related migration into Stage 2, GIL, and NCC should be prioritised over mortgages on a standalone basis. Mortgages are large and important as a potential channel for broad Stage 2 migration or higher ECL, but a sharp near-term increase in credit costs may be more likely to come from more cyclical corporate, SME, and commercial exposures.

4. Summary of Q&A Content

4.1 Funding and Liquidity Vulnerability

The purpose of the question was to identify which trigger in Maybank’s balance sheet would be most likely to affect credit quality first: short-term funding and foreign-currency funding costs, large deposits, or NPLs and credit costs. The initial response assumed a pathway in which outflows of short-term funding or large deposits would create liquidity pressure, followed by higher credit costs and pressure on CET1.

The follow-up refined and partly corrected this view. The question was whether, for a top-tier domestic bank such as Maybank, the more relevant early risk might be that NIM, profitability, and internal capital generation deteriorate first because the bank needs to raise deposit rates to retain deposits, rather than because of sudden deposit outflows themselves. The key response was that there may be phases in which the credit issue is not an “unstable deposit base” in a narrow liquidity sense, but a “higher-cost deposit base”, even if liquidity ratios do not immediately deteriorate.

The credit implication is that Maybank’s early-warning framework should not rely only on declines in LCR / NSFR. A sustained period in which NIM falls below 2.05%, a decline in the CASA ratio, simultaneous slowing deposit growth and rising funding costs, and wider foreign-currency funding spreads should be treated as warning signs for earnings and capital generation before they become signs of liquidity stress.

4.2 ROAR30, Strategic Investments, and Dividend Policy

The purpose of the question was to understand how the management plan, investment policy, M&A, asset sales, and shareholder return policy over the next 12–18 months could affect capital headroom and rating headroom in a downside scenario. The discussion response referred to ROAR30, technology, data, and AI investments, ROE / NIM / CIR / CASA targets, FY2026 loan growth guidance, and a dividend payout ratio in the 70% range. However, this report treats these as assertions from the discussion, and items not yet reflected in the existing issuer summary require re-confirmation against primary sources.

The follow-up asked whether technology, data, and AI investments said to be around RM10bn could lead to a near-term rise in CIR or pressure on PPOP, whether maintaining a dividend payout ratio in the 70% range could leave insufficient capital retention in a downside scenario, and whether M&A or asset sales could mitigate capital pressure. The key response was that ROAR30 investments alone would not necessarily impair CET1 immediately, but could become a secondary source of pressure on internal capital generation if they coincide with lower NIM, higher credit costs, sustained high dividends, and RWA growth.

The credit implication is that strategic investment should not be read only as a long-term positive. It should also be monitored in the following sequence: front-loaded near-term expenses, CIR deterioration, slower PPOP growth, and a decline in post-dividend CET1. In the absence of confirmed transactions or capital-enhancing measures, it is more conservative not to incorporate M&A or asset sales as risk mitigants at this stage.

4.3 Overseas Business Risk and ASEAN-Wide Stress

The purpose of the question was to assess whether, in a Maybank credit deterioration scenario, economic weakness or asset-quality deterioration in Singapore, Indonesia, and other ASEAN businesses could matter before domestic Malaysian factors. The initial response framed regional diversification as a stabilising factor in normal conditions, while also noting that simultaneous increases in credit costs across multiple markets could become a stress-transmission channel.

The follow-up asked whether the most important monitoring point is “asset-quality deterioration in Indonesia alone” or “ASEAN-wide stress involving simultaneous deterioration in Singapore, Indonesia, and the Malaysian parent”. The key response was that deterioration in Indonesia alone may remain absorbable at group earnings level, whereas simultaneous weakness in the economy, real estate, SME, and corporate credit across multiple markets could result in a combined increase in credit costs and a rapid deterioration in internal capital generation.

The credit implication is that overseas operations should not be viewed only as a single-country risk. Indonesia’s NPLs and credit costs should continue to be monitored, but the more severe scenario is one in which Stage 2, GIL, and CRE / SME delinquencies deteriorate simultaneously in Malaysia, Singapore, and Indonesia. Regional loans, regional NPLs, regional credit costs, and separate disclosures for Maybank Indonesia / Singapore remain items for future confirmation.

4.4 D-SIB Status, Government / Regulatory Support, and Instrument Hierarchy

The purpose of the question was to clarify how much credit benefit should be attributed to Maybank’s importance to the Malaysian financial system. The initial response stated that D-SIB status supports market confidence, short-term liquidity, and comfort around senior debt and deposits, but is not an explicit guarantee and does not eliminate loss-absorption risk for AT1 / Tier 2 instruments.

The follow-up asked in which circumstances support expectations would be strongest, and in which circumstances the market would be less likely to reprice positively on that basis. The key response was that when Maybank’s standalone capital and liquidity remain adequate and the issue is limited to market liquidity or depositor sentiment, D-SIB status can support confidence in senior debt and deposits. Conversely, when the CET1 buffer approaches regulatory requirements including the HLA, when the sovereign outlook deteriorates, when BNM signals capital conservation or dividend restraint, or when AT1 / Tier 2 spreads diverge from senior debt, standalone fundamentals and capital-structure risk come to the fore rather than support expectations.

The credit implication is that senior debt, Tier 2, and AT1 should not be evaluated using the same support expectations simply because the issuer is Maybank. D-SIB status supports the senior credit profile, but for capital instruments, the loss-absorption ranking, coupon discretion, non-viability provisions, write-off / conversion terms, and call economics must be assessed separately.

4.5 Domestic Macro Deterioration and Asset-Quality Transmission Sequence

The purpose of the question was to identify where NPLs, Stage 2 loans, and credit costs would be most likely to rise first in Maybank’s domestic loan portfolio if interest rates stayed high, employment weakened, consumption slowed, and property prices fell. The initial response stated that mortgages should not be viewed in isolation, and that SME, working-capital, commercial real estate, construction, and household delinquencies should be assessed separately.

The follow-up asked which sequence and combination of Stage 2, GIL, and NCC should be monitored to assess the pressure on internal capital generation and the CET1 buffer if credit costs rise simultaneously across several segments. The key response was that Stage 2 growth is the early warning, a higher GIL ratio is the crystallisation of deterioration, and an upward move in NCC is the direct trigger for internal capital generation. In assessing the CET1 buffer, these should be viewed together with post-dividend CET1, RWA growth, and the margin over regulatory requirements including the HLA.

The credit implication is that rating headroom would not be consumed by Stage 2 or GIL in isolation. The more relevant deterioration path is a scenario in which NCC clearly exceeds the approximately 20bps level discussed as FY2026 guidance and moves toward the 30–40bps range, while lower NIM, sustained high dividends, and RWA growth coincide, causing post-dividend CET1 to continue declining. This threshold should not be treated as an official rating-agency trigger, but as a portfolio-management warning line.

5. Ongoing Follow-Up Items and Candidates for Transfer to issuer_notes

This report does not update issuer_notes.md. The following are candidates that could be considered for transfer to the “management strategy, investment plan, and financial policy follow-up” section of issuer_notes.md in future research or report updates.

6. Unconfirmed Items

The discussion refers to additional information on ROAR30 targets, technology, data, and AI investments, dividend payout ratio, D-SIB HLA, Maybank Indonesia, and the domestic loan mix. However, these items have not been newly re-confirmed against primary sources at the time of preparing this report. Figures and measures not included in the existing issuer summary need to be re-checked against official materials, rating-agency materials, and regulatory materials at the time of the next update.

Items that remain particularly unconfirmed are the annual allocation of ROAR30 investments, the split between expensed, capitalised, and amortised costs, dividend policy under downside conditions, the practical approach to post-dividend CET1, the presence or absence of M&A or asset-sale plans, regional contributions to credit costs and NPLs, the latest asset quality of Maybank Singapore / Indonesia, rating-agency-specific support notching for Maybank’s D-SIB status, individual terms of AT1 / Tier 2 instruments, the Stage 2 breakdown for domestic Malaysia on a standalone basis, and delinquency, ECL, and NCC contributions by SME, Business Banking, CRE, and mortgages.

In addition, market data such as spread divergence between AT1 / Tier 2 and senior debt, foreign-currency funding spreads, and short-term market funding costs were not checked live in the discussion. These are useful practical indicators for portfolio management, but they are treated as unconfirmed items in this report.
