Liquidity Coverage Ratio: CAIIB BFM Guide to Bank Liquidity

The liquidity coverage ratio is a 30-day survival test. A bank must hold enough unencumbered high quality liquid assets (HQLA) to cover its total net cash outflows over a 30-calendar-day stress scenario, and the regulatory minimum is 100%. If the ratio falls below that, the bank is telling its supervisor it cannot fund itself for one month without help.

For CAIIB Bank Financial Management, this is one of the highest-yield topics in the risk module: the formula is short, the numbers are examinable, and the classification rules are where most candidates lose marks. This guide walks through the definition, HQLA levels, run-off factors, a full worked calculation and five exam-standard MCQs.

💧 What the Liquidity Coverage Ratio Actually Measures

The ratio answers one question: if wholesale funding dries up and depositors start withdrawing, does the bank hold enough assets it can convert into cash immediately, without a fire sale?

The formula is deliberately simple:

• LCR = Stock of HQLA ÷ Total net cash outflows over the next 30 calendar days
• Total net cash outflows = expected cash outflows − expected cash inflows
• Cash inflows recognised are capped at 75% of total expected cash outflows

That inflow cap is the single most tested nuance. Because a bank can never offset more than 75% of its outflows, net cash outflows can never fall below 25% of gross outflows. A bank cannot manufacture a comfortable ratio by claiming a wall of incoming repayments in the stress month.

The stress scenario itself is prescribed, not modelled by the bank. It combines a partial retail deposit run, a loss of unsecured wholesale funding, a partial loss of secured short-term funding, rating-downgrade triggers, derivative collateral calls and drawdowns on committed credit and liquidity lines. Every one of those events is converted into a percentage run-off factor.

Two features distinguish it from a traditional maturity ladder. First, it is a stock measure: the numerator is what you already own. Second, the buffer is meant to be usable — supervisors expect it to be drawn below 100% in genuine stress. If you are revising the wider risk framework, the Basel III case study chapter sets the capital and liquidity pillars side by side.

💡 Exam Tip: When a question gives you inflows larger than 75% of outflows, cap them first, then compute net cash outflows. Skipping the cap is the most common single-step error in numerical LCR questions.

🏦 HQLA: Level 1, Level 2A and Level 2B Assets

Not every liquid-looking asset qualifies. HQLA must be unencumbered, low risk, easy to value, listed on a developed exchange or otherwise readily saleable, and — critically — under the operational control of the treasury function that would monetise it in a crisis.

The stock is split into levels, each with its own haircut and cap:

Read the caps in the right order. Level 2B is squeezed to a maximum of 15% of the total stock, and Level 2A plus Level 2B together cannot exceed 40%. Both caps are applied after haircuts, so a portfolio stuffed with corporate bonds delivers far less headroom than its face value suggests.

Assets pledged against borrowings, held in a subsidiary that cannot upstream them freely, or used as margin are encumbered and drop out entirely. In India, government securities held to meet the statutory liquidity ratio count as Level 1 only to the extent regulation permits them to be reckoned for liquidity purposes, so treasury desks track the eligible slice separately from the SLR book.

Operational readiness matters as much as eligibility. A bank must periodically monetise a sample of the stock to prove market access. For the classroom treatment of these mechanics, work through Module B and C Class 7 alongside this guide.

📉 Run-Off Factors That Decide Net Cash Outflows

The denominator takes every liability and off-balance-sheet commitment maturing or callable inside 30 days and multiplies it by a prescribed run-off factor. The factors encode a simple belief: money that is insured, small and relationship-based stays; money that is wholesale, large and price-sensitive leaves. The standard hierarchy runs as follows:

1. Stable retail deposits — insured and held in a transactional relationship: lowest band (5%).
2. Less stable retail deposits — uninsured, high-value or rate-chasing balances: higher band (10%).
3. Operational wholesale deposits — clearing, custody and cash-management balances a client needs: 25%.
4. Non-operational deposits of non-financial corporates, sovereigns and PSEs: 40%.
5. Funding from financial institutions and all unsecured wholesale money without a relationship: 100%.

Secured funding is treated by the quality of the collateral: a repo against government securities rolls over almost fully, while a repo against equity attracts a heavy outflow. Undrawn committed facilities generate outflows on the undrawn portion, with liquidity lines to financial entities treated far more harshly than retail credit lines.

RBI has also tightened the treatment of digitally mobile money, adding an incremental run-off factor to internet- and mobile-banking-enabled deposits, on the reasoning that a balance which can leave in one tap is less sticky than a branch deposit. Check the current factor in the applicable circular on the Reserve Bank of India website before quoting a number, since these calibrations are revised.

Inflows follow a mirror logic: performing loans maturing in the window are recognised at 50%, interbank placements at 100%, and no inflow may be assumed from a facility granted to your bank by another bank.

⚠️ Common Mistake: Candidates classify a large uninsured corporate deposit as "retail" because the account sits in a branch. Classification follows the counterparty and the relationship, never the booking location.

🧮 A Worked Calculation in Exam Format

Take a bank with the following position, all figures in Rs crore.

Step 1 — build the HQLA stock. Level 1 assets are 8,000 and carry no haircut. Level 2A assets are 2,000; after the 15% haircut they contribute 1,700. Total stock is 9,700. Test the caps: Level 2 assets are 1,700 out of 9,700, which is about 17.5% — comfortably inside the 40% ceiling, so nothing is disallowed.

Step 2 — compute gross outflows. Stable retail deposits of 20,000 at 5% give 1,000. Less stable retail deposits of 10,000 at 10% give 1,000. Operational wholesale deposits of 8,000 at 25% give 2,000. Non-operational corporate deposits of 5,000 at 40% give 2,000. Funding from financial institutions of 3,000 at 100% gives 3,000. Total expected outflows are 9,000.

Step 3 — compute inflows and apply the cap. Performing loans of 4,000 mature in the window and are recognised at 50%, giving 2,000. The cap is 75% of 9,000, that is 6,750. Since 2,000 is well below the cap, the full 2,000 is admitted.

Step 4 — net off and divide. Net cash outflows are 9,000 − 2,000 = 7,000. The ratio is 9,700 ÷ 7,000 = 138.57%, comfortably above the 100% floor.

Now stress the same bank. If the financial-institution funding doubles to 6,000, outflows rise to 12,000, net outflows to 10,000 and the ratio collapses to 97%. That sensitivity is the examiner's favourite follow-up: one wholesale concentration drives the whole number. The same arithmetic discipline used in gap analysis in banks applies here — tabulate, apply the factor, then total.

Always test the 40% and 15% HQLA caps before dividing. A question that hands you a large Level 2B holding is testing the cap, not the division.

⚖️ How LCR Fits With the Rest of the Liquidity Framework

The ratio is a short-horizon tool and was never meant to stand alone. Its long-horizon partner, the net stable funding ratio, looks at a one-year window and asks whether long-dated assets are financed by durable liabilities. One is a stock buffer for 30 days; the other is a structural funding rule for a year. Exams frequently pair them in a single question, so learn the horizon and the numerator of each.

Alongside both sit the older tools that CAIIB still tests: structural liquidity statements with prescribed tolerance limits on the shorter buckets, dynamic liquidity statements, stock ratios such as loans to deposits and volatile liabilities to total assets, and internal stress tests with board-approved triggers. Interest-rate measures such as earnings at risk in banks answer a different question about the same balance sheet and should not be confused with liquidity metrics.

Governance is examinable too. The board sets liquidity risk tolerance, a designated committee approves the funding strategy and contingency funding plan, and the treasury executes within limits, with an independent mid-office monitoring breaches. Disclosure is part of the regime: banks publish the ratio as a simple average of daily observations, along with the HQLA composition and funding concentration.

Supervisory reporting deadlines are not the only clocks a bank runs against — data incidents carry their own statutory timelines, covered in our note on DPDP Act breach notification norms.

🎯 Final Revision Checklist

Learn three things cold: the formula, the two HQLA caps (40% for Level 2, 15% for Level 2B) and the 75% inflow cap. Everything else in a numerical question is arithmetic. Pair this with the structural liquidity statement and the one-year funding rule, and the liquidity block of BFM becomes reliable marks rather than guesswork.
