Working Capital Management: CAIIB ABM Comprehensive Guide 2026

Working capital management is one of the highest-weightage topics in the CAIIB Advanced Bank Management (ABM) paper, and a thorough grasp of its concepts, methods, and regulatory nuances is essential for every serious exam candidate. Working capital management refers to the process by which banks assess, sanction, monitor, and review short-term credit facilities extended to business borrowers to finance their day-to-day operational needs — raw material procurement, production, storage, and receivables. In the Indian banking context, this discipline is shaped by landmark committee reports, RBI guidelines, and credit policy frameworks that have evolved over decades.

Understanding the Operating Cycle

The foundation of working capital management lies in understanding the operating cycle (also called the cash conversion cycle), which measures the time a business takes to convert its investment in raw materials into cash receipts from sales. For a manufacturing unit, the operating cycle typically flows through five stages: raw material storage period → work-in-progress (WIP) period → finished goods storage period → debtors' (receivables) collection period, minus the creditors' payment period (since suppliers grant credit that funds part of the cycle).

The gross operating cycle is the sum of all four holding/collection periods, while the net operating cycle deducts the creditor payment period. The net operating cycle directly determines the bank's estimate of how many days of operating cost need to be financed externally — a longer cycle implies a larger working capital gap and a higher credit requirement.

Bankers calculate the operating cycle using the following ratios derived from projected financials:

  • Raw material holding period = (Average raw material stock / Raw material consumed) × 365
  • WIP holding period = (Average WIP / Cost of production) × 365
  • Finished goods holding period = (Average finished goods / Cost of goods sold) × 365
  • Debtors collection period = (Average debtors / Net credit sales) × 365
  • Creditors payment period = (Average creditors / Purchases) × 365

A sound understanding of the operating cycle helps a bank credit officer determine the reasonableness of a borrower's working capital demand. CAIIB ABM questions frequently test the ability to compute the net operating cycle and link it to the bank's financing obligation. For additional practice on quantitative problems, explore the mock tests on iibf.store, which include operating-cycle numericals at exam difficulty.

Tandon and Chore Committee Methods

Two watershed committee recommendations fundamentally shaped how Indian banks assess and sanction working capital limits: the Tandon Committee (1975) and the Chore Committee (1979). CAIIB ABM candidates must know both in detail, including the three Tandon methods and the Chore Committee's modifications.

Tandon Committee — Three Methods of Lending

The Tandon Committee, constituted by RBI and chaired by P.L. Tandon, introduced the concept of Maximum Permissible Bank Finance (MPBF). The committee defined a minimum level of net working capital (NWC) that the borrower must contribute from long-term sources, thereby ensuring that banks do not finance 100% of current assets.

  1. Method I: Bank finances up to 75% of the total current assets (TCA) minus the total current liabilities other than bank borrowings (OCL). The borrower must fund the remaining 25% of TCA from NWC.
    MPBF = 75% of (TCA − OCL)
  2. Method II: Bank finances up to 75% of TCA minus OCL, but the borrower's minimum NWC contribution must be at least 25% of TCA (not just 25% of the net current assets). Method II is more conservative and requires a higher borrower contribution.
    MPBF = 75% of TCA − OCL
  3. Method III: The borrower's NWC must cover the entire core current assets (CCA) — the irreducible minimum inventory a business must always hold. Only non-core current assets above the CCA level are financed by the bank. This method was never formally implemented.

In practice, Method II became the standard for all borrowers with fund-based working capital limits above ₹10 lakh (subsequently revised). The key formula to remember: Current Ratio must be at least 1.33:1 under Method II, since if NWC = 25% of TCA, then CA/CL = 4/3.

Chore Committee — Modifications

The Chore Committee (1979) reviewed the Tandon framework and recommended stricter discipline. Key changes included: mandatory quarterly information system (QIS) returns from borrowers, separation of loan and cash credit components (loan portion to be repaid out of profits), and tighter bifurcation of working capital demand loans (WCDL) from running cash credit. The Chore Committee also stressed bifurcation of limits into short-term demand loans versus revolving cash credit to enforce better discipline in credit use.

MPBF, Turnover Method, Nayak Method, and Cash Budget

Working capital management in Indian banking uses several distinct assessment methods depending on the size of borrowal and the nature of the borrower. CAIIB ABM tests all of them with numerical problems.

Maximum Permissible Bank Finance (MPBF)

MPBF, derived from the Tandon Committee's Method II, is the starting point for large borrowers. The process involves collecting the borrower's projected current assets and current liabilities for the next 12 months, computing the working capital gap (TCA − OCL), and then restricting bank finance to 75% of that gap. The remaining 25% must come from the borrower's own long-term funds.

Item₹ Lakhs
Total Current Assets (TCA)400
Other Current Liabilities (OCL)100
Working Capital Gap (TCA − OCL)300
25% Borrower Margin (from NWC)75
MPBF (75% of Gap)225

Turnover Method (for small borrowers)

For borrowers with credit limits up to ₹5 crore (as per the Nayak Committee norms later revised by RBI), the Turnover Method simplifies assessment. Working capital is taken as 25% of the projected annual turnover, of which 20% is financed by the bank and 5% is the borrower's margin contribution. The formula: Working Capital Limit = 20% of Projected Annual Turnover. This method avoids the detailed balance-sheet analysis required under MPBF and is particularly useful for small traders and manufacturers.

Nayak Committee Method

The Nayak Committee (1992), set up specifically for small-scale industries (SSI), recommended that working capital limits for SSI units should be computed as a minimum of 20% of projected annual sales turnover, to be provided by banks as a composite loan (combining term loan and working capital). This is now extended to MSMEs. The Reserve Bank of India has endorsed this approach for micro and small enterprises — see the RBI website for circulars on MSME lending guidelines. CAIIB ABM frequently asks candidates to calculate the Nayak method limit and compare it with MPBF to identify which is higher and must be sanctioned.

Cash Budget Method

The Cash Budget Method is used for borrowers with seasonal businesses (sugar mills, tea processing, construction) or those where cash flows are highly irregular. Instead of relying on projected balance sheets, the bank analyses month-by-month cash inflows and outflows. The working capital limit equals the peak deficit (maximum net cash shortfall) in the annual cash budget. This approach is also mandated for NBFCs, real-estate developers, and film producers. Candidates must know the distinction: MPBF uses projected balance sheets; the cash budget uses cash flows.

Drawing Power, Margins, and Credit Monitoring

Sanctioning a working capital limit is only the first step. Ongoing drawing power computation and margin maintenance are critical to safe banking, and CAIIB ABM tests this aspect under credit management and monitoring.

Drawing Power (DP)

Drawing power is the amount a borrower is permitted to draw from the cash credit (CC) account at any given point in time. It is calculated based on the current value of the primary security (stocks and receivables) after deducting the prescribed margin. The formula:

Drawing Power = (Value of stock + Receivables up to 90 days) × (1 − Margin%)

For example, if a borrower holds stock worth ₹200 lakh and debtors of ₹80 lakh (within 90 days), and the bank's margin is 25%, then:

  • Total security = ₹200 + ₹80 = ₹280 lakh
  • Drawing Power = ₹280 × 75% = ₹210 lakh

The outstanding balance in the CC account must never exceed the drawing power. If it does, the account is said to be irregular. Banks obtain monthly stock statements (and quarterly QIS returns for larger limits) to recompute DP continuously.

Margins

Margin represents the portion of the asset value that the borrower self-finances, acting as a cushion against stock depreciation, fraud, or valuation errors. RBI has from time to time prescribed minimum margins for different categories:

  • Raw material: typically 25%
  • WIP: typically 33.33%
  • Finished goods: typically 25%
  • Book debts (up to 90 days): typically 40%
  • Export receivables: typically 10–15% (lower, to support exports)

Margins are prescribed by the bank's internal credit policy within RBI's broad guidelines and may vary by borrower rating, industry, and nature of security. Understanding how margins reduce drawing power is a recurring theme in CAIIB ABM numerical questions.

Monitoring Working Capital Accounts

Post-sanction monitoring involves: verifying monthly stock statements, ensuring the account is not chronically near-limit (suggesting evergreening), tracking debtor age-analysis to exclude overdue receivables from DP computation, and conducting annual review of limits. The Quarterly Information System (QIS) — introduced by the Chore Committee — requires borrowers with CC limits above ₹1 crore to submit Form I (estimated operations for current quarter), Form II (actual operations for preceding quarter), and Form III (half-yearly operating statement). Failure to submit QIS or deviations beyond prescribed limits can trigger limit reduction or account classification as irregular.

Key Formulas and Quick-Reference Summary

CAIIB ABM's quantitative section frequently tests working capital formulas under time pressure. A consolidated quick-reference is essential for revision.

Formula Sheet

ConceptFormula / Rule
Net Operating CycleRM days + WIP days + FG days + Debtor days − Creditor days
Tandon Method I MPBF75% × (TCA − OCL)
Tandon Method II MPBF75% × TCA − OCL (NWC ≥ 25% of TCA; CR ≥ 1.33)
Turnover Method Limit20% of Projected Turnover
Nayak Method LimitMin. 20% of Projected Annual Sales
Drawing Power(Stocks + Debtors ≤ 90 days) × (1 − Margin%)
Cash Budget MethodPeak monthly cash deficit in projected 12-month budget

Common Exam Traps

  • Tandon Method II requires NWC ≥ 25% of TCA, not 25% of net current assets — a distinction that changes the MPBF figure.
  • Debtors older than 90 days are excluded from drawing power computation entirely.
  • Nayak Committee norms set a floor — if MPBF gives a higher figure, the higher amount should be sanctioned.
  • Cash Budget Method is for seasonal/irregular businesses, NOT the standard method for manufacturing units.
  • WIP carries the highest margin (33.33%) because it has the lowest realisation value in a distress sale.

What is the difference between Tandon Method I and Method II?

Under Method I, the bank finances 75% of the Working Capital Gap (TCA minus OCL), and the borrower's NWC only needs to cover the remaining 25% of the gap. Under Method II, the borrower's NWC must be at least 25% of Total Current Assets — a stricter requirement. This results in a lower MPBF under Method II and mandates a minimum current ratio of 1.33:1. Method II became the standard in Indian banking practice.

When is the Cash Budget Method used instead of MPBF?

The Cash Budget Method is used when the borrower's cash flows are seasonal or highly irregular — for example, sugar mills, tea factories, construction companies, NBFCs, real-estate developers, and film producers. Since these businesses have lumpy inflows and outflows, a month-by-month cash flow projection gives a more accurate picture of the peak financing need than a projected balance sheet. The bank sanctions a limit equal to the highest monthly net cash deficit.

How is Drawing Power different from the sanctioned limit?

The sanctioned limit is the maximum facility approved by the bank after credit appraisal — it does not change unless a formal review or enhancement is done. Drawing power, on the other hand, is dynamic and changes every month based on the value of stocks and receivables (after deducting the prescribed margin) as reported in the monthly stock statement. The borrower can draw only up to the lower of the sanctioned limit or the current drawing power. If DP falls below the outstanding balance, the account becomes irregular.

What does the Nayak Committee method prescribe for MSMEs?

The Nayak Committee (1992) recommended that banks provide working capital finance to SSI (now MSME) units at a minimum of 20% of their projected annual turnover. Of this, the bank's contribution is 20% and the borrower's own margin is 5%, making total working capital 25% of turnover. Banks must offer at least this level of working capital to eligible MSMEs as a matter of policy. RBI has periodically reiterated these norms and extended them to micro and small enterprises across sectors.

Conclusion: Master Working Capital Management to Score High in CAIIB ABM

Working capital management is not just a theoretical topic — it is the bread-and-butter of day-to-day banking operations, and the CAIIB ABM paper tests it with a mix of conceptual questions and numerical problems. From computing the net operating cycle and applying the correct assessment method (MPBF, Turnover, Nayak, or Cash Budget) to calculating drawing power and understanding QIS monitoring requirements, every sub-topic is examinable. The Tandon and Chore committee frameworks remain the bedrock of Indian bank credit appraisal, and their formulas must be memorised with precision.

Candidates who build a strong conceptual foundation and practice a wide variety of numericals consistently outperform those who rely on rote learning.
