LCR and NSFR Ratios Explained for CAIIB BFM Exam

LCR and NSFR ratios are the two Basel III liquidity standards that decide whether a bank can survive a sudden funding shock, and they are among the highest-yield, most repeatable scoring topics in the CAIIB Bank Financial Management (BFM) paper. Master the formulas, the thresholds and the small print, and you have locked in marks that the examiner asks in some form almost every cycle. This guide rebuilds both ratios from first principles, walks through solved sums the way they appear in the exam, and gives you a tight revision plan so the numbers become automatic.

Both standards exist because the 2008 global financial crisis exposed a brutal lesson: a bank can be perfectly solvent on paper and still fail simply because it runs out of cash. Capital adequacy answers the question “is the bank solvent?” The LCR and NSFR ratios answer a different and equally vital question — “can the bank actually pay what it owes, on time, even when funding markets freeze?” BFM tests both ideas, and confusing the two is the fastest way to lose easy marks. For a structured walk-through of the entire syllabus with solved examples, the CAIIB exam hub on Learning Sessions sequences every module logically.

What the LCR and NSFR ratios actually measure

Think of the two ratios as a short-term shock absorber and a long-term suspension system. The Liquidity Coverage Ratio asks whether a bank could withstand a severe, acute 30-day cash drain — the kind of week where depositors panic and wholesale lenders refuse to roll over funding. The Net Stable Funding Ratio asks a slower, structural question: is the bank financing its long-dated assets with funding that is genuinely sticky over a one-year horizon, rather than chasing cheap overnight money that can evaporate?

Put simply, the LCR is about asset liquidity in a crisis week, while the NSFR is about funding stability across a year. A bank can pass one and fail the other, which is exactly why the Basel Committee insisted on both. The Reserve Bank of India implemented the LCR in phases before it reached its full requirement, and the NSFR followed later for scheduled commercial banks; regional rural banks, local area banks and payment banks sit outside the standard framework. Treat the precise commencement dates and current minimums as time-sensitive — they are best verified against the latest released RBI notification rather than memorised blindly.

The LCR formula and the 100% floor

The Liquidity Coverage Ratio is defined as:

The intuition is clean. A bank must hold at least one rupee of high-quality, easily sellable assets for every rupee of net cash it expects to lose during a 30-day stress scenario. If the ratio dips below 100%, the bank is signalling that a bad month could leave it short of cash even after liquidating its safest holdings.

What counts as HQLA

Not every asset qualifies, and not every qualifying asset counts at full value. The framework sorts liquid assets into tiers and applies haircuts so that only genuinely cash-like holdings get full credit:

• Level 1 assets — cash, excess CRR balances, eligible central-bank reserves and government securities (including SLR holdings and amounts available under facilities such as MSF/FALLCR). Counted at 100% of value with no cap.
• Level 2A assets — certain high-rated corporate bonds and qualifying PSU securities, subject to a 15% haircut.
• Level 2B assets — lower-rated corporate bonds and qualifying equities, carrying deeper haircuts (typically 25%–50%).

Two caps trip up candidates constantly: Level 2 assets together are capped at 40% of total HQLA, and within that, Level 2B is sub-capped at 15%. If you forget these limits, your HQLA figure will be overstated and your LCR answer will be wrong even when the arithmetic looks tidy.

Computing total net cash outflows

The denominator is where the real exam craft lies. Total net cash outflows equal total expected outflows minus the lesser of (a) total expected inflows or (b) 75% of total expected outflows. That 75% ceiling is deliberate: the regulator refuses to let a bank assume it will be fully rescued by incoming cash during a crisis, forcing it to keep a hard buffer of liquid assets. Outflows themselves are weighted by run-off factors — for instance, stable retail deposits attract a low 5% run-off, less stable retail around 10%, and unsecured wholesale funding far more, because corporate and interbank money flees fastest. To make these weightings second nature, drill the timed MCQs on the CAIIB mock tests until you stop second-guessing them.

The NSFR formula and the logic of stable funding

The Net Stable Funding Ratio shifts the lens from assets to liabilities and stretches the horizon to a full year:

The governing idea is that long-lived assets must be backed by long-lived funding. A bank that funds 20-year mortgages with overnight borrowings is playing with fire, and the NSFR penalises exactly that mismatch. Like the LCR, the floor is 100%, but here you are comparing how much stable money the bank has against how much it structurally needs.

Available Stable Funding (the numerator)

ASF is the slice of capital and liabilities expected to stay with the bank over one year, each multiplied by a factor that reflects how sticky that funding is:

• Tier 1 and Tier 2 capital, plus liabilities with an effective maturity of one year or more — 100% ASF.
• Stable retail and small-business deposits (under one year) — 95% ASF.
• Less stable retail deposits — 90% ASF.
• Wholesale funding from non-financial corporates (under one year) — 50% ASF.
• Short-term funding from financial institutions — 0% ASF, because interbank money is the flightiest of all.

Required Stable Funding (the denominator)

RSF weights each asset by how illiquid or long-dated it is. Cash and short-term claims on banks carry very low RSF factors; unencumbered residential mortgages and performing loans carry moderate factors; and illiquid, encumbered or long-term assets approach a 100% RSF factor. The more an asset would be hard to sell or is locked up, the more permanent funding it must be matched against. To cement which factor attaches to which asset class, the gamified CAIIB matching games let you pair each item with its correct weight at speed.

LCR vs NSFR: a side-by-side comparison

When the paper throws a conceptual MCQ, it almost always probes whether you can tell the two ratios apart. Burn this table into memory:

A worked LCR example, step by step

Numerical questions look intimidating until you follow a fixed sequence. Suppose a bank reports HQLA of Rs 600 crore, expected 30-day cash outflows of Rs 800 crore, and expected inflows of Rs 300 crore.

1. Apply the inflow cap. The ceiling is 75% of outflows = 0.75 × 800 = Rs 600 crore. Actual inflows of Rs 300 crore are lower, so you use the smaller figure, Rs 300 crore.
2. Compute net cash outflows. 800 − 300 = Rs 500 crore.
3. Divide. LCR = 600 ÷ 500 = 120%, comfortably above the 100% floor.

Now change one number to see why the cap matters. If inflows had been Rs 700 crore, the 75% ceiling of Rs 600 crore would bind instead. Net outflows would then be 800 − 600 = Rs 200 crore, and the LCR would jump to 600 ÷ 200 = 300%. The examiner loves this switch precisely because careless candidates plug in the full Rs 700 crore and get a wrong answer. Whenever inflows look large, check the 75% cap first.

A practical revision plan for the BFM paper

Knowing the theory is not the same as scoring under time pressure. Use this compact study sequence in the final fortnight before BFM:

1. Day 1–2: build intuition. Re-read the purpose of each ratio until you can explain LCR vs NSFR to a friend in one sentence each. Conceptual clarity prevents the most common MCQ errors.
2. Day 3–5: memorise the factors. Drill HQLA levels, haircuts, run-off factors, and ASF/RSF weights using flashcards and the matching games.
3. Day 6–9: grind numericals. Solve at least 30 LCR and NSFR sums, deliberately mixing cases where the 75% inflow cap binds and where it does not.
4. Day 10–12: simulate the exam. Attempt full-length timed mock tests and review every mistake the same day.

This ratio topic connects naturally to the rest of BFM risk management, so reinforce it alongside the broader Bank Financial Management module. If interest-rate risk is also on your weak list, the companion guide on Bond Duration and Convexity for CAIIB BFM pairs perfectly with liquidity risk for a complete treasury picture.

Common mistakes to avoid

• Ignoring the 40% Level 2 cap (and the 15% Level 2B sub-cap) when totting up HQLA — this inflates the numerator.
• Using inflows in full instead of the lesser of actual inflows or 75% of outflows.
• Mixing up the two ratios — treating the LCR (30-day, asset-side) as if it were the NSFR (one-year, funding-side), or vice versa.
• Forgetting haircuts on Level 2A (15%) and Level 2B (25%–50%) assets.
• Quoting outdated thresholds. Always cross-check current minimums and applicability against the latest RBI/IIBF circular rather than an old note.

This same liquidity-and-stability mindset underpins credit risk too, so candidates often revise it alongside NPA management and asset classification under Basel III, which sits squarely in the same regulatory family.

Frequently Asked Questions

What is the minimum LCR a bank must maintain?

Under the Basel III framework as adopted by the RBI, banks must maintain a Liquidity Coverage Ratio of at least 100%. This means their high-quality liquid assets must fully cover the total net cash outflows expected over a 30-calendar-day severe stress scenario. The RBI introduced the requirement in phases before it reached the full level, so always confirm the current floor against the latest released RBI notification.

How do the LCR and NSFR ratios differ?

The LCR is a short-term, 30-day measure of whether a bank’s liquid assets can cover stressed cash outflows. The NSFR is a structural, one-year measure of whether stable funding sources adequately support the bank’s assets. In short, the LCR focuses on asset liquidity in a crisis week, while the NSFR focuses on funding stability across a year. Both share a 100% minimum but answer different questions.

What qualifies as High Quality Liquid Assets (HQLA)?

HQLA are assets that can be converted to cash quickly with little or no loss of value. Level 1 assets such as cash, excess CRR and government securities count at full value with no cap. Level 2A assets take a 15% haircut and Level 2B assets take deeper haircuts of roughly 25% to 50%. Importantly, all Level 2 assets together are capped at 40% of total HQLA, with Level 2B sub-capped at 15%.

Why is the cash inflow capped at 75% in the LCR?

The 75% cap forces a bank to hold a minimum cushion of liquid assets rather than assuming it will be bailed out by incoming cash during stress. Total net cash outflows equal expected outflows minus the lesser of actual inflows or 75% of outflows. Because of this rule, even a bank expecting large inflows must still keep a hard buffer of HQLA, which is the most frequently tested twist in BFM LCR sums.

Does the NSFR apply to all banks in India?

The NSFR applies to scheduled commercial banks operating in India under the standard framework. Regional rural banks, local area banks and payment banks generally fall outside this standard application. Because applicability and effective dates can change with regulatory updates, confirm the exact scope against the latest IIBF or RBI circular before relying on it in the exam.

How are the LCR and NSFR ratios useful for the CAIIB BFM exam?

They are high-yield because their formulas, the 100% floors, the HQLA caps and the 75% inflow rule recur in the BFM paper almost every cycle. Questions appear as both direct numericals and conceptual comparisons, so a candidate who has drilled the factors can usually answer them quickly. Treating them as guaranteed-scoring topics, rather than optional ones, is one of the smartest moves in BFM preparation.

Conclusion: lock in these ratios before your BFM exam

The LCR and NSFR ratios reward disciplined preparation more reliably than almost any other BFM topic, because the same formulas, floors, caps and the 75% inflow rule surface paper after paper. Build the intuition first, then drill the numericals until the run-off, ASF and RSF factors are automatic and the inflow cap is the first thing you check. Do that, and these become marks you bank with confidence rather than questions you fear. Keep going — treasury and risk topics are where focused candidates pull ahead.
