Principles of Bank Lending and Credit Policy

Introduction

Lending is the central transforming function of a commercial bank. A bank mobilises deposits and other funds, evaluates borrowers, creates credit, and allocates purchasing power to households, enterprises, farmers and public institutions. Interest income from lending is usually the principal source of bank revenue, but lending also exposes the bank to credit, liquidity, market, operational, legal, reputational and concentration risks.

Sound lending therefore requires more than willingness to lend or the existence of collateral. It requires a disciplined assessment of the borrower, the purpose and repayment source, the structure of the facility, the risks involved and the bank’s own legal and financial capacity. Credit policy converts these principles into practical rules governing who may borrow, for what purposes, on what terms, with what authority and under what monitoring arrangements.

This chapter explains the principles of bank lending, the contents of credit policy, lending powers, fund-based and non-fund-based facilities, and the structuring of retail, MSME, agricultural and corporate credit.

1. The Nature and Economics of Bank Lending

A loan is an arrangement under which a bank provides funds or undertakes a financial obligation for a customer, with repayment expected according to agreed terms. The bank’s return commonly consists of interest, fees, commissions and other charges. The borrower’s repayment normally comes from income, business cash flow, sale proceeds, investment income or an identified refinancing source.

The fundamental transformation performed by a bank has three dimensions:

• Maturity transformation: deposits may be repayable on demand while loans mature later.
• Risk transformation: a bank diversifies many individual exposures and manages them within a portfolio.
• Liquidity transformation: deposits are highly liquid, whereas loans are generally less liquid.

These transformations create economic value but also create vulnerability. If a borrower fails to repay, the bank may suffer a loss. If many depositors demand withdrawal simultaneously, the bank may face liquidity pressure even when its loan portfolio is economically sound. Credit policy must therefore reconcile the interests of borrowers, depositors, shareholders, regulators and the wider economy.

A bank’s basic lending decision can be expressed conceptually as:

Probability of Default (PD) is the likelihood that the borrower will default over a specified horizon. Exposure at Default (EAD) is the amount outstanding or likely to be drawn when default occurs. Loss Given Default (LGD) is the proportion not recovered after considering repayments, collateral and recovery costs. This relationship is a risk-management model rather than a complete pricing formula. It assumes the three components are defined consistently and over the same time horizon.

2. Core Principles of Bank Lending

2.1 Safety

Safety means the reasonable protection of the principal lent and the interest due. A safe loan is not necessarily risk-free; rather, its risk is identified, measured, accepted within limits and controlled.

Safety assessment includes:

• character and integrity of the borrower;
• financial strength and repayment capacity;
• quality and stability of cash flows;
• industry and economic conditions;
• quality of collateral and guarantees;
• legal enforceability of the documentation; and
• adequacy of monitoring and early-warning systems.

The traditional “five Cs of credit” help operationalise safety:

Modern credit analysis adds cash flow, compliance, concentration and climate or environmental risk to this traditional framework.

2.2 Liquidity

Liquidity is the ability to obtain cash when required without unacceptable loss. A loan should be compatible with the bank’s funding profile. Short-term and self-liquidating facilities, such as working-capital finance against receivables, generally support liquidity better than long-term, highly illiquid exposures funded entirely by short-term deposits.

Liquidity analysis considers the maturity pattern of deposits and loans, expected repayments, access to wholesale funding, marketability of securities and contingency funding arrangements. A loan may be profitable and well secured yet unsuitable if it creates excessive maturity or funding risk.

2.3 Profitability

Lending must provide an adequate risk-adjusted return. The lending rate should compensate for the cost of funds, operating expenses, expected credit loss, capital usage and a reasonable profit margin.

A simplified pricing relationship is:

This is an approximation, not a universal pricing identity. All components must be measured on a comparable annual basis. Competitive conditions, regulation, taxes, liquidity premiums and relationship value may also affect the final price.

Profitability should be assessed over the entire relationship, including account balances, payment services, fees, foreign exchange business and future opportunities. However, cross-selling must not be used to justify an intrinsically unsafe loan.

2.4 Purpose

The purpose principle requires the bank to know why funds are requested and to ensure that they are used for the stated purpose. Purpose affects risk, tenor, repayment source, documentation and monitoring.

Examples include:

• housing finance for purchase or construction of a dwelling;
• a vehicle loan for acquisition of a specified vehicle;
• seasonal agricultural finance for inputs and crop production;
• working-capital finance for inventory and receivables; and
• term finance for machinery or expansion.

A sound loan has a clear end use and a credible primary repayment source. Collateral is a secondary source of repayment, not a substitute for viable cash flow. Diversion of funds, speculative use, connected-party lending and financing of illegal activities violate prudent lending standards.

2.5 Diversification

Diversification reduces the effect of an individual or correlated default. A bank should avoid excessive concentration by borrower, group, industry, geography, currency, collateral type, product or maturity.

Diversification does not mean lending indiscriminately. A portfolio of many borrowers in the same declining industry may remain highly concentrated in economic substance. Portfolio management therefore considers correlations and common risk drivers, not merely the number of accounts.

2.6 Security

Security refers to assets, rights or commitments supporting repayment. Common forms include:

• Primary security: the asset or current asset financed by the loan, such as inventory or a vehicle.
• Collateral security: additional property or financial assets offered by the borrower or a third party.
• Guarantee: a person or institution promises to pay if the borrower fails.
• Assignment: specified rights or receivables are transferred or charged in favour of the bank.
• Lien, pledge, hypothecation and mortgage: legal mechanisms giving the bank varying rights over assets.

Security should be valued conservatively, insured where appropriate, legally perfected, periodically revalued and readily enforceable. The loan-to-value ratio is commonly expressed as:

Loan amount and collateral value must be measured at the same point in time and in the same currency. The applicable value should reflect prudent valuation, including appropriate haircuts where market prices are volatile. LTV is a risk indicator, not proof of repayment capacity.

3. Credit Policy and Lending Powers

3.1 Meaning of Credit Policy

Credit policy is the approved framework that guides the acquisition, appraisal, sanction, documentation, pricing, monitoring, classification and recovery of credit exposures. It translates the bank’s strategy and risk appetite into operational standards.

A comprehensive policy normally covers:

1. target markets and excluded activities;
2. acceptable products, currencies, tenors and repayment structures;
3. borrower eligibility and minimum information requirements;
4. financial analysis and cash-flow assessment;
5. collateral, guarantees, valuation and insurance;
6. pricing, fees, risk grades and provisioning;
7. exposure, sectoral and geographic limits;
8. delegated authority and approval hierarchy;
9. documentation, disbursement and conditions precedent;
10. monitoring, covenant testing and early warning;
11. problem-loan management, restructuring and recovery; and
12. compliance with law, regulation, sanctions, consumer protection and anti-money-laundering requirements.

Policy should be sufficiently specific to control risk but sufficiently flexible to accommodate sound judgment. It should be reviewed periodically in response to economic conditions, regulatory changes, portfolio performance and emerging risks.

3.2 Lending Powers and Delegated Authority

A bank’s lending powers arise from its governing law, licence, constitutional documents, regulatory rules and internal board-approved delegations. The board typically sets risk appetite and major limits; senior management implements policy; credit committees approve exposures within their mandate; and individual officers approve smaller facilities within delegated limits.

A sound delegation system requires:

• written limits by amount, product, risk grade and borrower type;
• separation of relationship management, credit approval and loan operations;
• independent risk review for significant exposures;
• enhanced approval for related-party and connected lending;
• documentation of exceptions and their expiry dates; and
• escalation when limits are breached or risk changes materially.

Delegation is not abdication. A senior officer remains responsible for the design and supervision of the system, while the approving officer remains responsible for decisions within delegated authority. No employee should approve a facility solely because it is commercially attractive or requested by an influential person.

4. Fund-Based and Non-Fund-Based Facilities

4.1 Fund-Based Facilities

A fund-based facility involves an actual or potential disbursement of the bank’s funds.

A term loan normally has a defined amount, tenor and repayment schedule. A working-capital line permits drawings within a limit, subject to margin requirements and periodic review. A bank should not use a short-term overdraft indefinitely to finance a permanent fixed asset; such mismatch obscures the borrower’s financial condition and increases liquidity risk.

4.2 Non-Fund-Based Facilities

A non-fund-based facility initially involves a contingent commitment rather than immediate disbursement. It can nevertheless become a funded exposure if the customer fails to perform.

Important examples are:

• Bank guarantee: the bank promises payment to a beneficiary if specified conditions are met or the customer defaults.
• Letter of credit: the bank undertakes to pay a seller against compliant documents, subject to the applicable rules and terms.
• Acceptance or aval: the bank adds its credit standing to a bill or payment obligation.
• Standby letter of credit: a contingent payment undertaking, often used as credit support.

Non-fund-based exposures require assessment of the applicant’s financial strength, transaction purpose, expiry, claim conditions, counterparty, margin and potential conversion into a funded loan. Fees should reflect risk and capital usage. The bank must monitor outstanding commitments and ensure that expired instruments are cancelled promptly.

5. The Credit Process

The credit process is a controlled sequence rather than a single approval event.

5.1 Origination and Preliminary Screening

The bank identifies the applicant, purpose, requested amount, tenor and repayment source. Know-your-customer procedures establish identity, beneficial ownership, business activity, tax status and sanctions exposure. Preliminary screening may reject prohibited sectors, incomplete applications or requests clearly inconsistent with policy.

5.2 Appraisal

Appraisal combines qualitative and quantitative analysis. For individuals, it includes income stability, existing obligations, credit history, employment and household expenses. For businesses, it includes management quality, business model, industry position, audited accounts, projected cash flow, working-capital cycle, leverage and sensitivity to adverse conditions.

A useful debt-service measure is:

Cash Flow Available for Debt Service should be defined consistently, usually as cash available before scheduled principal and interest payments. Total Debt Service includes principal and interest due during the same period. A DSCR greater than 1 indicates nominal coverage, but the acceptable level depends on sector volatility, income stability, collateral and policy standards. It is not meaningful if cash flow is overstated or periods are mismatched.

5.3 Structuring and Approval

Structure should match the purpose and cash-flow cycle. Key terms include amount, tenor, grace period, interest basis, fees, repayment frequency, margin, security, covenants and conditions precedent. The credit memorandum should explain the proposal, risks, mitigants, exceptions and recommendation.

5.4 Documentation and Disbursement

Legal documents establish the obligation and security. Before disbursement, the bank verifies execution, authority, registration or perfection of security, insurance, equity contribution, licences and fulfilment of conditions. Disbursement should be linked to verified invoices, construction stages or other evidence where misuse is possible.

5.5 Monitoring and Recovery

Monitoring includes financial statements, account conduct, stock and receivables reports, covenant compliance, site visits, insurance, collateral value and external warning signals. Warning signs include overdue payments, unexplained limit excesses, falling turnover, returned cheques, tax arrears, frequent management changes and adverse legal information.

If deterioration occurs, the bank may intensify monitoring, restrict further drawings, obtain additional support, restructure a viable exposure or commence recovery. Restructuring should restore realistic repayment capacity, not merely postpone recognition of loss.

6. Structuring Major Credit Segments

6.1 Retail Credit

Retail lending includes housing, vehicle, education, personal and credit-card facilities. It relies on standardised products, verified income, credit-bureau information, affordability tests and automated or score-assisted decisions.

A responsible retail structure should consider:

• stable and verifiable income;
• existing debt obligations and essential living expenses;
• interest-rate and employment stress;
• loan-to-value and borrower contribution;
• insurance and title documentation; and
• transparent pricing, fees and early-settlement terms.

Retail credit can be diversified across many borrowers, but correlated unemployment, property-price declines or aggressive unsecured lending can generate substantial portfolio losses.

6.2 MSME Credit

Micro, small and medium enterprises often have limited audited information, informal records, concentrated customers and volatile cash flows. This does not make them unbankable; it requires proportionate, relationship-based analysis.

The lender should examine bank statements, tax filings, sales records, invoices, inventory, supplier relationships, owner withdrawals and business premises. Cash-flow-based lending may be supported by receivables assignment, inventory control, movable-asset security, guarantees or partial credit guarantees. The owner’s personal finances and business finances should be separated as far as possible.

A working-capital facility should reflect the operating cycle. If inventory is held for 60 days and customers pay after 30 days, while suppliers provide 20 days of credit, the approximate cash conversion cycle is:

In this illustration, the cycle is 70 days. The formula assumes the three measures are calculated consistently and represent average operating behaviour. It helps determine the period for which the enterprise must finance operations, but it does not by itself determine the facility amount.

6.3 Agricultural Credit

Agricultural lending is affected by seasonality, weather, biological cycles, commodity prices, land tenure and infrastructure. The product should be linked to the crop or livestock cycle rather than imposed on a uniform monthly schedule.

Assessment should include land or cultivation rights, cropping pattern, historical yields, input costs, irrigation, market access, insurance, farmer experience and local climate risks. Repayment may be scheduled after harvest or through multiple seasonal receipts. Diversification by crop, geography and borrower is essential. Responsible agricultural lending avoids encouraging excessive indebtedness where income is highly uncertain.

6.4 Corporate Credit

Corporate lending may include term loans, revolving working capital, project finance, syndicated loans, trade finance and guarantees. Analysis should cover consolidated financial statements, group structure, related parties, cash-flow forecasts, leverage, interest coverage, refinancing risk, covenant headroom and legal enforceability.

Large exposures require independent review and concentration analysis. Project finance focuses primarily on the project’s future cash flow, construction risk, contracts, sponsors, permits and completion guarantees. Corporate facilities may include financial covenants such as maximum leverage, minimum interest coverage or restrictions on additional borrowing. Covenants are useful only when clearly defined, measurable and actively monitored.

7. Illustrative Case: Financing a Growing Food-Processing MSME

This is a fictional case for educational purposes.

Background

FreshHarvest Foods, an established food-processing MSME, seeks a working-capital line and a term loan to install packaging equipment. It sells to supermarkets and restaurants. Sales are growing, but receivables have lengthened because two large buyers now pay after 45 days.

Problem

The relationship manager proposes a large overdraft based on projected sales. The credit analyst notes that the business has limited audited history, seasonal inventory requirements and dependence on two buyers. The proposal also risks using short-term funds for the equipment purchase.

Analysis

The bank verifies tax filings, bank statements, invoices, buyer confirmations and supplier terms. It estimates inventory days at 50, receivable days at 45 and payable days at 25. The cash conversion cycle is therefore 70 days. Sensitivity analysis tests a 15% fall in sales, a 10-day increase in collections and a rise in input prices.

The primary repayment source is operating cash flow. The packaging equipment should be financed separately through a four-year term loan, while the operating cycle should be supported through a borrowing-base working-capital line. The bank obtains a charge over inventory and receivables, insurance over the equipment and a limited promoter guarantee, subject to law and policy.

Approach and Solution

The bank approves:

• a term loan with scheduled quarterly repayments aligned with projected cash flow;
• a revolving working-capital limit reviewed at least annually;
• monthly inventory and receivables reporting;
• confirmation of major receivables and concentration limits;
• a minimum owner contribution to the equipment purchase; and
• covenants requiring timely financial information and no material additional borrowing without consent.

Disbursement for equipment is made directly against supplier invoices. The working-capital line is reduced if eligible receivables or inventory fall below agreed levels.

Outcome

The structure avoids using a permanent overdraft for a fixed asset, links borrowing to verified current assets and provides early warning if buyer concentration or collection performance worsens. The bank earns interest and fees while limiting the risk created by optimistic sales projections.

Learning Points

1. The purpose principle determines facility type and tenor.
2. Cash flow remains the primary repayment source.
3. Collateral and guarantees mitigate loss but do not cure weak economics.
4. Working-capital limits should reflect the operating cycle and eligible assets.
5. Covenants and reporting convert approval into continuing risk management.

8. Ethics, Governance and Regulation

Credit decisions affect livelihoods and economic opportunity, so they require integrity and fairness. Officers must avoid bribery, conflicts of interest, favouritism, insider lending, discriminatory practices and manipulation of valuations or financial statements. Customer information must be protected, and terms must be communicated clearly.

Regulatory expectations commonly include capital adequacy, asset classification, provisioning or expected-loss recognition, large-exposure limits, related-party controls, consumer protection, anti-money-laundering controls and fair treatment of distressed borrowers. Exact rules vary by jurisdiction; students and practitioners must consult the applicable central-bank and banking laws.

Technology improves credit assessment through digital records, bureau data, transaction analysis and machine-learning models. Nevertheless, models can reproduce historical bias, rely on poor-quality data or become unstable during structural economic change. Human oversight, explainability, data governance, cybersecurity, model validation and a right to review adverse decisions are therefore important. Automation should strengthen—not eliminate—accountability.

9. Challenges and Best Practices

Major challenges include information asymmetry, weak documentation, rapid interest-rate changes, fraud, cyber risk, climate events, property-price volatility, connected lending and pressure for loan growth. Best practice includes:

• independent and evidence-based appraisal;
• cash-flow-first analysis;
• prudent valuation and legal perfection of security;
• risk-based pricing and adequate capital allocation;
• portfolio limits and stress testing;
• segregation of duties;
• continuous monitoring and early intervention;
• accurate classification and timely provisioning;
• responsible restructuring; and
• periodic policy review informed by portfolio data.

Chapter Summary

Bank lending allocates funds while transforming maturity, risk and liquidity. Because lending exposes a bank to default and funding risk, decisions must apply the principles of safety, liquidity, profitability, purpose, diversification and security. Safety depends principally on character, capacity and cash flow; collateral is a secondary protection.

Credit policy establishes target markets, acceptable risks, products, appraisal standards, limits, pricing, delegated authority, documentation, monitoring and recovery procedures. Lending powers derive from law, regulation and internal delegation, with segregation of duties and accountability essential to governance.

Fund-based facilities involve actual or potential disbursement, whereas non-fund-based facilities create contingent obligations such as guarantees and letters of credit. Retail, MSME, agricultural and corporate borrowers require different structures because their income patterns, information quality, operating cycles and risks differ. Effective lending matches tenor and repayment schedule to purpose and cash flow, monitors changing conditions and treats ethics, consumer protection, regulation and technology as integral components of credit quality.
