Credit Rating vs Bank Credit Appraisal

An external credit rating and a bank's own internal credit appraisal are two related but genuinely distinct assessments of the same company, built for different purposes, using overlapping but not identical information, and arriving at conclusions that can — and sometimes do — diverge.

Two Parallel but Different Assessments

It is a common misconception, particularly among first-time borrowers, that a company's external credit rating and its bank's internal view of its creditworthiness are essentially the same thing expressed in different formats. They are not. An external rating from a SEBI-registered credit rating agency is a standardised, published opinion, benchmarked against a broad universe of comparable companies across the entire market, produced by an entity with no direct lending exposure to the company and no stake in the outcome of any specific facility decision. A bank's internal credit appraisal, by contrast, is a proprietary, generally unpublished assessment conducted by the specific lending bank, tailored to that bank's own risk appetite, portfolio composition, and the specific facility being considered, produced by an entity that does have direct exposure to the outcome.

Both assessments typically draw on much of the same underlying raw material — audited financial statements, business plans, industry data, management discussions — but they process that material through different lenses, weight different factors differently, and are accountable to different audiences: the rating agency to the broader market of investors and lenders who rely on the published rating, and the bank's internal team to its own credit committee and, ultimately, its regulator.

What the External Rating Typically Covers

An external rating assessment generally evaluates the company's overall credit risk profile in a facility-agnostic way — business risk (industry position, competitive standing, demand outlook), financial risk (leverage, coverage, liquidity, profitability trends), and management and governance quality — arriving at a single symbol intended to represent the company's general ability and willingness to service its debt obligations across its rated instruments as a whole, rather than a view calibrated to any one specific facility from any one specific lender.

What the Bank's Internal Appraisal Covers Additionally

A bank's internal appraisal generally goes further in several specific, facility-relevant directions that an external rating, by its more general nature, typically does not. This includes a detailed assessment of the specific facility being requested — its purpose, structure, tenure, and security package; a granular review of the company's cash flow adequacy specifically for servicing the proposed facility on top of its existing obligations; the adequacy and enforceability of the collateral or other security being offered; the bank's own exposure limits and sectoral or group-level concentration considerations, which are entirely internal to the bank and have nothing to do with the company's general creditworthiness; and, where the company already banks with the institution, the bank's own account conduct history and relationship data, which an external rating agency generally does not have direct access to in the same granular, transaction-level form.

The bank's internal appraisal also incorporates the bank's own risk appetite and portfolio strategy at the point in time the proposal is being considered — a bank that is, for internal strategic reasons, reducing its overall exposure to a particular sector may decline or scale back a proposal from a company with a strong external rating, purely because of the bank's own portfolio-level considerations that have nothing to do with the specific company's credit quality.

Why the Two Views Can Diverge

Because the external rating and the bank's internal appraisal are built for different purposes from overlapping but non-identical information, and because the bank's internal view incorporates facility-specific and bank-specific considerations the external rating simply does not address, it is entirely normal — not a red flag in either direction — for the two to diverge to some degree. A company can have a strong external rating and still face a cautious or declined internal appraisal from a specific bank because of that bank's sector concentration limits, prior relationship experience, or internal risk appetite at that particular time. Equally, a company with a more modest external rating can sometimes secure favourable internal appraisal outcomes from a bank that has deep, positive, long-standing relationship experience with it that the external rating, by its more standardised nature, does not fully capture.

Timing differences also contribute to occasional divergence. An external rating is reviewed and updated on its own periodic and event-driven cycle, discussed in the surveillance-focused pillar of this content series, while a bank's internal appraisal is refreshed each time a facility is proposed, renewed, or materially modified — meaning the two assessments are not always looking at exactly the same point-in-time information, particularly for a company whose financial position is moving quickly in either direction.

How Banks Reconcile the Two Views in Practice

Where a bank's internal assessment differs meaningfully from a company's external rating, most banks do not simply pick one over the other by default; the bank's credit team typically investigates the specific basis for the divergence, since a material gap between the two views is itself informative. If the bank's internal view is more cautious than the external rating, the credit team will generally want to understand and document the specific factors driving that caution — often facility-specific, security-specific, or relationship-specific factors of the kind described above rather than a disagreement with the rating agency's fundamental credit assessment. If the bank's internal view is more favourable than the external rating, the credit team may still proceed on the strength of its own relationship-based conviction, though this is somewhat less common in practice, particularly at larger exposure sizes where the regulatory capital and governance implications of overriding an external rating's implied risk level are more carefully scrutinised internally.

Practical Implications for Borrowers

For a company navigating this dynamic, the practical takeaway is twofold. First, a strong external rating is a genuinely valuable asset in a lending conversation but should never be treated as a guarantee of a favourable internal appraisal outcome at any specific bank, for the reasons set out above — the two exercises are related but not interchangeable. Second, and equally important, investing in the underlying relationship with the bank — transparent, proactive communication, disciplined account conduct, timely sharing of information beyond the minimum required — has real, independent value that a strong external rating alone does not substitute for, because it directly shapes the half of the picture that the external rating does not and cannot capture.

Illustrative Example

Consider a hypothetical textile manufacturer with a solid A-category external rating applying for an enhanced working capital limit at a bank where it has banked for only about eighteen months. The bank's internal appraisal, while acknowledging the favourable external rating, proceeds cautiously — the bank's relationship history is still relatively short, and the bank's internal exposure limit to the textile sector as a whole is close to its internal ceiling for internal portfolio-diversification reasons entirely unrelated to this specific company's credit quality. The proposal is ultimately sanctioned, but at a somewhat smaller enhancement than requested and with a slightly more conservative security package than the company's rating alone might have suggested, illustrating how bank-specific and sector-specific internal considerations can shape an outcome independently of a genuinely strong external rating.

Frequently Asked Questions

If my external rating is strong, why did my bank still ask so many detailed questions?

Because the bank's internal appraisal covers facility-specific, security-specific, and relationship-specific ground that an external rating, by design, does not address. A strong rating is a positive input, not a substitute for the bank's own full appraisal process.

Can a bank lend to a company with no external rating at all?

Yes, particularly for smaller exposures below the threshold where external ratings become material for the bank's regulatory capital treatment, or where the bank has a long, well-documented relationship history that substitutes, in the bank's own internal judgement, for the comparative benchmarking an external rating would otherwise provide.

Does a bank ever share its internal appraisal or internal rating with the company?

Generally not the full internal appraisal or the bank's internal risk grade, since this is considered proprietary to the bank's own credit process, though some banks will share directional feedback on request, particularly where a proposal has been declined or scaled back and the relationship is otherwise being maintained.

Should a company get a second external rating if one bank's internal appraisal is unfavourable?

Not usually as a first response. Since the divergence is more often driven by bank-specific or facility-specific factors than by a flaw in the external rating itself, it is generally more productive to understand the specific basis for the bank's internal view before assuming the external rating needs to be revisited.
