Loan Review Mechanism and Active Portfolio Management - Article

Introduction

Credit-risk management does not end when a loan is sanctioned.

After credit is granted, a bank must continuously determine whether:

• the original credit decision remains valid;

• the borrower's risk has changed;

• internal ratings remain accurate;

• sanction conditions and policies are being followed;

• weaknesses are being identified early; and

• the overall credit portfolio continues to match the bank's risk appetite.

Two important mechanisms support these objectives:

1. Loan Review Mechanism (LRM) — an independent review of individual credit exposures and the quality of the credit process.

2. Active Credit Portfolio Management (ACPM) — deliberate management of the composition, concentration and risk-return profile of the overall credit portfolio.

The current 2026 CAIIB BFM syllabus covers Portfolio Credit Risk, Credit Risk Measurement, risk concentrations and portfolio-level credit-risk management concepts in Module B.

Current Basel credit-risk principles require banks to maintain independent, ongoing assessment of credit-risk management processes and to manage risk both in individual exposures and across the entire portfolio.

The relationship can be understood simply:

LRM asks: “Are individual credits and the credit process being managed properly?”

ACPM asks: “Does the overall portfolio contain the right mix of risk and return?”

Learning Objectives

After studying this topic, you should be able to:

• explain the purpose of a Loan Review Mechanism;

• distinguish loan review from normal account monitoring;

• understand why loan review should be independent;

• identify important areas covered by a credit review;

• understand how LRM supports rating accuracy and early-warning identification;

• explain Active Credit Portfolio Management;

• identify important portfolio-management techniques;

• understand the role of loan transfers and securitisation; and

• distinguish individual-credit control from portfolio-level risk management.

What Is a Loan Review Mechanism?

A Loan Review Mechanism is a structured system for independently reviewing credit exposures and assessing whether the bank's credit-granting, administration and monitoring processes are functioning effectively.

It provides a second view of the credit after origination.

The loan review function may examine:

• quality of credit appraisal;

• sanction terms;

• compliance with credit policy;

• internal credit rating;

• documentation;

• disbursement;

• account conduct;

• borrower financial condition;

• collateral;

• covenant compliance;

• early-warning indicators;

• classification of problem credits; and

• adequacy of follow-up.

Basel's current credit-risk principles specifically require an independent, ongoing assessment of the bank's credit-risk management processes, with review results communicated to the Board and senior management.

Why Is Loan Review Necessary?

The originating branch or business unit may naturally focus on:

• customer relationships;

• business growth;

• timely sanction; and

• income generation.

These objectives are legitimate, but they can create the possibility of optimistic credit judgement.

An independent review provides challenge.

It helps identify:

• weak appraisal assumptions;

• policy deviations;

• incorrect ratings;

• deteriorating borrowers;

• poor post-sanction supervision;

• inadequate security;

• concentration concerns; and

• weaknesses in the credit process.

Basel states that internal credit reviews performed independently of the business function provide important assessment of both individual credits and the overall quality of the portfolio.

Independence of LRM

Independence is one of the most important principles.

The person who originated or approved a credit should not have complete control over the independent review of that same credit.

An independent review function should be capable of:

• questioning the original assumptions;

• challenging an internal rating;

• identifying policy deviations;

• recommending increased monitoring; and

• escalating material weaknesses.

Basel requires responsibility for setting or confirming internal ratings to rest with a credit-review function independent of the originating function, with periodic independent examination of rating consistency and accuracy.

Loan Review vs Normal Credit Monitoring

These concepts are related but not identical.

Normal monitoring asks:

“Is the borrower performing as expected?”

Loan review additionally asks:

“Has the bank itself correctly assessed and managed this exposure?”

Main Objectives of Loan Review Mechanism

1. Verify Credit Quality

LRM evaluates whether the current risk level of the account has been correctly recognised.

A borrower classified as low risk at sanction may have deteriorated subsequently.

Review should identify whether:

• rating needs revision;

• monitoring should increase;

• exposure should be reduced; or

• the account requires remedial attention.

2. Validate Internal Credit Ratings

Internal ratings influence:

• credit decisions;

• pricing;

• limits;

• monitoring;

• capital and risk assessment; and

• portfolio reporting.

An inaccurate rating can therefore distort several risk-management decisions.

Current Basel guidance requires borrower ratings to be periodically reviewed and changed when conditions improve or deteriorate.

3. Detect Weaknesses Early

Loan review should identify deterioration before loss becomes severe.

Examples include:

• repeated excesses;

• declining sales;

• increasing leverage;

• covenant breaches;

• rating migration;

• falling collateral coverage;

• delays in financial information; and

• weak account conduct.

Early identification allows the bank to act while more options remain available.

4. Check Compliance with Credit Policy

LRM may review whether:

• credit was sanctioned within delegated authority;

• policy exceptions were properly approved;

• exposure limits were followed;

• required conditions were imposed;

• documentation was completed; and

• disbursement complied with sanction terms.

Repeated policy deviations across many loans may indicate a systemic weakness rather than an isolated mistake.

5. Evaluate Credit Administration

The review may assess:

• documentation;

• security creation;

• insurance;

• charge registration;

• renewal of documents;

• stock and receivable monitoring;

• end-use verification; and

• post-disbursement supervision.

RBI supervisory material specifically treats the adequacy of the loan review mechanism, monitoring of large exposures, documentation, collateral verification, end-use and problem-credit monitoring as important components of credit-risk control.

6. Assess Portfolio Quality

Individual reviews can reveal patterns such as:

• repeated weaknesses in one industry;

• increasing rating downgrades;

• poor underwriting in one product;

• unusually high policy exceptions; or

• concentration in weak borrowers.

Therefore, LRM contributes to portfolio management as well as individual-account control.

Scope and Coverage of Loan Review

Not every exposure necessarily requires identical depth of review.

A risk-based review mechanism may give greater attention to:

• large exposures;

• high-risk accounts;

• deteriorating ratings;

• policy exceptions;

• stressed industries;

• connected groups;

• newly introduced products;

• restructured or specially monitored exposures; and

• other accounts selected according to bank policy.

The important principle is that review coverage should be sufficient to provide a reliable view of credit quality.

Frequency of Review

Higher-risk or deteriorating credits generally require more frequent attention than stable low-risk accounts.

Basel specifically notes that credits with deteriorating ratings should receive additional oversight, including enhanced monitoring and possible inclusion on a watchlist reviewed by senior management.

Review frequency should therefore reflect:

• exposure size;

• risk rating;

• complexity;

• borrower condition;

• sector risk; and

• emerging warning signals.

Reporting and Follow-Up

A loan review has limited value unless its findings produce action.

Material findings may require:

• rating correction;

• enhanced monitoring;

• rectification of documentation;

• reduction or freezing of exposure;

• additional security;

• reconsideration of limits;

• remedial management; or

• changes in credit policy.

The review system should also identify recurring patterns.

For example, if repeated reviews show weak project-cost assessment across several branches, management may need to improve the credit process, not merely correct individual accounts.

Basel requires review results to be communicated directly to senior management and the Board where appropriate.

What Is Active Credit Portfolio Management?

Traditional lending often follows a buy-and-hold approach:

Originate the loan → Hold it until repayment or maturity.

Active Credit Portfolio Management takes a broader view.

It treats the bank's loan book as a portfolio whose composition can be deliberately managed to achieve an acceptable balance of:

• risk;

• return;

• concentration;

• capital usage; and

• liquidity.

The objective is not merely to make each loan acceptable.

It is to create an overall portfolio consistent with the bank's risk appetite and strategic objectives.

RBI has historically described Credit Portfolio Management as a means to reduce undesirable concentration, improve the risk-return profile of the loan portfolio and enhance the efficient use of capital.

Why Active Portfolio Management Is Needed

Suppose every new loan is individually acceptable.

Over time, the bank may still become heavily exposed to:

• commercial real estate;

• one corporate group;

• one geographical region;

• one borrower rating category; or

• one common economic risk.

Individual sanction decisions can therefore produce an undesirable portfolio when viewed collectively.

ACPM aims to correct this.

Main Objectives of Active Credit Portfolio Management

Improve Diversification

The bank may seek to reduce excessive exposure to:

• one borrower;

• one connected group;

• one sector;

• one geography;

• one product; or

• one common risk factor.

Improve Risk-Adjusted Return

Two loans with the same nominal interest rate may not provide the same economic return if their:

• PD;

• LGD;

• capital usage;

• operating cost; and

• concentration effect

are different.

Portfolio management therefore seeks an appropriate risk-return balance, not merely the highest lending yield.

Manage Concentration

Portfolio managers examine whether new lending increases or reduces existing concentration.

For example, a high-quality real-estate loan may still be unattractive if the bank is already heavily exposed to real estate.

Optimise Capital

Credit assets use regulatory and economic capital.

A portfolio-management approach considers whether capital is being used efficiently relative to the risk and return generated.

Improve Liquidity and Flexibility

A bank may transfer eligible loan exposures instead of holding every originated loan until maturity.

The RBI's Transfer of Loan Exposures Directions state that loan transfers may be used for purposes including liquidity management, rebalancing exposures and strategic sales. The Master Direction currently listed by RBI is the 2021 framework updated as on 28 December 2023.

Active Portfolio Management Techniques

1. Control New Origination

One of the simplest portfolio-management tools is changing future lending.

If a sector is already heavily concentrated, the bank may:

• reduce new sanctions;

• apply tighter underwriting;

• reduce maximum exposure;

• increase risk-sensitive pricing; or

• prioritise other segments.

This gradually changes portfolio composition without selling existing loans.

2. Adjust Internal Limits

Limits may be revised for:

• sectors;

• borrower groups;

• ratings;

• geographies; or

• products.

The objective is to prevent further accumulation of an undesirable concentration.

3. Allow Natural Run-Off

The bank may allow existing loans to:

• amortise;

• mature; or

• remain unrenewed,

thereby gradually reducing exposure.

This avoids forced disposal but may take time.

4. Transfer Loan Exposures

Eligible loans may be transferred under the applicable RBI framework.

Loan transfers can assist:

• exposure rebalancing;

• concentration reduction;

• liquidity management; and

• strategic portfolio changes.

A transfer does not mean that underwriting quality becomes unimportant. Banks should maintain proper credit standards and comply with applicable regulatory requirements.

5. Securitisation

Securitisation redistributes credit risk by pooling eligible assets and repackaging them into securities.

RBI's Securitisation of Standard Assets Directions, 2021 recognise that prudently structured securitisation can facilitate risk distribution and improve lenders' liquidity for originating further credit.

Securitisation should not be interpreted as automatic removal of all risk. Applicable retention, due-diligence, capital and other regulatory requirements remain relevant.

6. Credit-Risk Transfer and Hedging

Where permitted and appropriate, credit-risk transfer instruments may help alter the portfolio's exposure to particular risks.

The bank must understand:

• what risk is actually transferred;

• residual risk;

• counterparty risk;

• legal enforceability; and

• cost of protection.

A hedge that reduces one risk may introduce another.

7. Portfolio Diversification

The bank may deliberately develop business in:

• different industries;

• different geographical markets;

• different borrower segments; or

• exposures driven by different economic factors.

However, diversification should be based on economic risk, not merely the number of accounts.

Loan Review Mechanism and ACPM Work Together

LRM and ACPM should not be viewed as separate systems.

Loan review produces information about:

• borrower deterioration;

• rating accuracy;

• underwriting weaknesses;

• policy exceptions;

• problem sectors; and

• emerging portfolio trends.

Portfolio management converts this information into strategic action.

For example:

LRM finding: Several textile borrowers are being downgraded.

Portfolio implication: Textile-sector risk is increasing.

ACPM response: Restrict new textile exposure, tighten underwriting, stress the existing portfolio and consider reducing concentration.

Thus:

Loan Review → Risk Information → Portfolio Analysis → Strategic Action

Role of Internal Ratings

Internal risk ratings connect individual-credit monitoring with portfolio management.

Ratings help banks:

• identify deterioration;

• compare borrowers;

• create watchlists;

• analyse rating migration;

• identify concentration by risk grade; and

• determine whether credit strategy needs adjustment.

Basel states that internal ratings can help management track the current characteristics of the credit portfolio and determine necessary changes to credit strategy.

Therefore, inaccurate ratings can weaken both:

• individual credit decisions; and

• portfolio-management decisions.

Practical Banking Application

Assume a bank's loan review function examines a sample of large infrastructure accounts.

It identifies that:

• several accounts have been downgraded;

• project completion is delayed;

• cost overruns are increasing;

• some sanction assumptions are no longer valid; and

• aggregate infrastructure exposure is already high.

At the individual-account level, the bank may:

• revise ratings;

• increase monitoring;

• reassess repayment capacity;

• strengthen controls; and

• initiate remedial action where necessary.

At the portfolio level, management may:

• reassess the sector limit;

• restrict additional infrastructure exposure;

• stress-test the portfolio;

• redirect future lending toward less correlated sectors; or

• explore appropriate exposure-rebalancing methods.

This illustrates the difference:

LRM identifies and validates the problem.

ACPM decides how the portfolio should be changed in response.

Loan Review Mechanism vs Active Portfolio Management

CAIIB Exam Focus

Remember these important points:

• Loan review is different from ordinary account monitoring.

• LRM should provide independent assessment and challenge.

• The originating business function should not have complete control over independent credit review.

• Loan review covers both individual credit quality and weaknesses in the credit process.

• Internal ratings require periodic review.

• Deteriorating credits require closer monitoring.

• Loan review findings should lead to corrective action.

• Repeated findings across accounts may indicate systemic underwriting or monitoring weakness.

• ACPM focuses on the overall portfolio, not merely individual borrowers.

• Individually acceptable loans can collectively create excessive concentration.

• Portfolio management seeks an appropriate risk-return balance.

• Changing new origination is itself an active portfolio-management technique.

• Exposure can decline through natural run-off or permitted loan transfers.

• Loan transfers can assist liquidity management and portfolio rebalancing.

• Securitisation can redistribute credit risk and improve liquidity, subject to applicable regulation.

• Diversification should consider common economic risk drivers.

• LRM provides information that can influence portfolio strategy.

• Internal ratings link individual-credit risk with portfolio-level analysis.

• Active portfolio management does not remove the need for strong underwriting.

Common Exam Traps

Trap 1: “Loan review and normal loan monitoring are the same.”

Incorrect. Monitoring is an ongoing operational activity. Loan review provides independent assessment of credit quality and the effectiveness of the credit process.

Trap 2: “The originating officer should independently review the same credit.”

Misleading. Independent review should be sufficiently separated from the originating function to provide objective challenge.

Trap 3: “LRM is useful only after an account becomes NPA.”

Incorrect. An important purpose is to identify deterioration before serious loss or default occurs.

Trap 4: “Loan review examines only documentation.”

Incorrect. It may examine appraisal quality, ratings, borrower performance, policy compliance, monitoring and portfolio implications.

Trap 5: “A portfolio of individually sound loans does not require active management.”

Incorrect. Concentrations and correlations can make the overall portfolio risky.

Trap 6: “Active portfolio management means selling bad loans.”

Incorrect. It includes origination controls, limits, diversification, run-off, transfers, securitisation and other portfolio actions.

Trap 7: “A loan should always be held until maturity once sanctioned.”

Incorrect. Subject to applicable law, regulation and policy, eligible loan exposures may be transferred as part of portfolio management.

Trap 8: “Securitisation eliminates all credit risk for the originating bank.”

Incorrect. Regulatory retention requirements and other residual risks may remain.

Trap 9: “Portfolio management can compensate for weak underwriting.”

Incorrect. Active portfolio management complements, but cannot replace, sound credit appraisal and underwriting.

Trap 10: “Independent credit review has no role in portfolio strategy.”

Incorrect. Review findings can reveal rating migration, sector weakness and systemic deficiencies that should influence future credit strategy.

Memory Technique

Remember R–R–A for Loan Review:

R — Review: Independently examine credit quality. R — Re-rate: Correct ratings when risk changes. A — Act: Escalate weaknesses and obtain corrective action.

For Active Portfolio Management, remember L–D–T–R:

L — Limits: Control concentration. D — Diversify: Add less-correlated risks. T — Transfer: Rebalance eligible exposures where appropriate. R — Risk–Return: Maintain the desired portfolio balance.

The connection is simple:

LRM tells management what is changing. ACPM determines what to do with the overall portfolio.
