Working Capital Assessment — CAIIB ABM 2026 Guide

Few topics decide more CAIIB marks than working capital assessment. Every lending banker must judge how much short-term finance a business genuinely needs to fund its operating cycle — too little and the borrower chokes, too much and the money leaks into diversion or fixed assets. In the CAIIB Advanced Bank Management paper, examiners test whether you can move confidently between the operating cycle, the different assessment methods, and the arithmetic of Maximum Permissible Bank Finance. This 2026 guide covers all of it in an exam-ready sequence, so you can both understand the logic and score the numericals.

The Operating Cycle: Where Working Capital Begins

Working capital exists because cash does not return instantly. In a manufacturing firm, cash buys raw materials, which sit in stores, become work-in-progress, then finished goods, then debtors, and finally cash again. The length of this operating cycle — expressed in days — drives how much finance the business needs. A longer cycle locks up more money in current assets.

The cycle is measured by adding the holding periods and subtracting the credit the firm itself enjoys:

• Raw material holding period — average stock of raw materials ÷ daily consumption.
• WIP period — time material spends in production.
• Finished goods period — how long stock waits before sale.
• Debtor collection period — average receivables ÷ daily credit sales.
• Less: creditor payment period — the free credit suppliers extend.

Gross working capital is the total of current assets; net working capital is current assets minus current liabilities, and reflects the long-term funds a firm has sunk into current assets. A positive net working capital signals liquidity and is central to the current ratio. Candidates using the CAIIB course should be able to compute a cycle from a given balance sheet in under three minutes.

Methods of Assessment

Banks assess working capital requirements using different methods depending on the size of the limit. For small borrowers, the turnover method (also called the Nayak Committee method) is common: working capital is taken as 25% of projected annual turnover, of which the borrower brings 5% as margin and the bank funds 20%. It is simple and suits accounts below a threshold.

For larger exposures, the Maximum Permissible Bank Finance (MPBF) method flowing from the Tandon Committee is used. There are two lending norms you must know:

• First method: MPBF = 75% of working capital gap, where the gap is current assets minus current liabilities other than bank borrowing. The borrower funds the remaining 25%.
• Second method: the borrower must fund 25% of total current assets from long-term sources, so MPBF = (75% of current assets) − other current liabilities. This method demands a higher current ratio of about 1.33:1.

Beyond these, large corporates use cash budget and projected balance sheet methods, which assess the peak deficit month by month rather than through ratios. Practising these calculations on our CAIIB mock tests is the fastest way to build speed for the exam hall.

Margin, Drawing Power and Discipline

Sanctioning a limit is only half the job — the bank controls disbursement through drawing power. Drawing power is computed from the stock-and-book-debt statement the borrower submits, applying prescribed margins: for example, 25% margin on paid stocks and a higher margin on book debts, with debts beyond a permitted age excluded entirely. The lower of the sanctioned limit and the drawing power governs how much can actually be drawn.

This monthly discipline prevents over-financing and flags stress early — a falling drawing power often precedes an NPA. Bankers also watch the current ratio and the composition of current assets to detect diversion of short-term funds into fixed assets or investments, a classic red flag. The broader supervisory expectations around credit discipline are set by the RBI, whose master directions you can consult at the Reserve Bank of India.

Common Numerical Traps and How to Avoid Them

Working-capital numericals catch students in predictable ways. First, confusing gross and net working capital: read whether the question asks for total current assets or the net figure after current liabilities. Second, forgetting to exclude existing bank borrowing when computing the working capital gap in the Tandon first method. Third, misapplying margins — the borrower's stake reduces bank finance, so a higher margin means a smaller limit.

A disciplined approach helps: lay out current assets and current liabilities in two columns, identify what the question is testing, then apply the exact formula. For the second Tandon method, always start by carving out 25% of current assets as the borrower's long-term contribution. Label your working so partial marks are earned even if the final figure slips.

To build fluency, alternate reading with retrieval practice on our concept match game, which pairs each method with its formula, and review solved examples on the exam blog. Consistent numerical drilling is what separates a pass from a distinction in Advanced Bank Management.
