Liquidity and Reserves Management: Strategies and Policies: formula sheet
Key formulas
- Liquidity Coverage Ratio (LCR)
- LCR = Stock of HQLA ÷ Total net cash outflows over the next 30 days ≥ 100%
- Short-term resilience under a 30-day stress. HQLA means high-quality liquid assets.
- Net Stable Funding Ratio (NSFR)
- NSFR = Available stable funding ÷ Required stable funding ≥ 100%
- One-year structural measure that limits maturity mismatch.
- Survival horizon
- Survival horizon = number of days the bank can meet outflows under stress using its liquid resources
- A common appetite metric. The board sets a minimum number of days.
- Liquidity gap
- Net gap in a time bucket = Cash inflows − Cash outflows
- A cumulative negative gap shows a funding need to be covered by buffers.
- Liquidity Coverage Ratio
- LCR = Stock of HQLA ÷ Total net cash outflows over the next 30 calendar days ≥ 100%
- Net outflows are stressed outflows minus the lesser of stressed inflows and 75% of outflows.
- Net cash outflows (LCR)
- Net outflows = Outflows − min(Inflows, 75% × Outflows)
- Inflows are capped at 75% of outflows, so net outflows are at least 25% of outflows.
- HQLA after haircut
- Adjusted value = Market value × (1 − haircut)
- Level 1 has no haircut. Level 2A has 15%. Level 2B has larger haircuts, such as 25% for qualifying RMBS and 50% for qualifying corporate equities.
- Composition caps
- Level 2 ≤ 40% of HQLA; Level 2B ≤ 15% of HQLA (after haircuts)
- Caps are applied after haircuts and adjusted for secured transactions maturing within 30 days.
- Survival horizon
- Survival days = Buffer ÷ Average daily stressed net outflow
- A simple internal measure. It assumes outflows are even, which stress rarely is.
- Cumulative net stressed outflow
- Net outflow(t) = Σ stressed outflows(1..t) − Σ stressed inflows(1..t)
- Calculate for each day up to the survival horizon. The peak value drives buffer size.
- Required buffer
- Required buffer = max over scenarios of (peak cumulative net outflow + contingency needs)
- Size to the most severe scenario, not the average.
- Stressed value of buffer
- Stressed value = Market value × (1 − haircut)
- Use for each asset. Only unencumbered assets count.
- Survival horizon test
- Survives to day T if buffer stressed value + other counterbalancing capacity ≥ cumulative net outflow(t) for every t ≤ T
- The horizon is the last day this holds. It is a path test, not a single-day test.
- Liquidity Coverage Ratio (Basel III)
- LCR = Stock of HQLA ÷ Total net cash outflows over next 30 calendar days ≥ 100%
- Net outflows = outflows − min(inflows, 75% of outflows).
- Funding concentration ratio
- Concentration = Funding from largest counterparties ÷ Total funding
- Compare with the policy limit. Define the group (top 5, top 10) exactly as the question does.
- Share of funding source
- Share = Funding from source ÷ Total funding × 100%
- Use to compare wholesale versus retail reliance.
- Loan-to-deposit ratio
- LTD = Loans ÷ Customer deposits
- A higher ratio means more reliance on non-deposit funding. It is a rough indicator, not a regulatory ratio.
- Net Stable Funding Ratio (Basel III)
- NSFR = Available stable funding ÷ Required stable funding ≥ 100%
- Encourages stable, longer-term funding for less liquid assets over a one-year horizon.
- Maturity ladder rollover gap
- Gap in bucket = Assets maturing in bucket − Liabilities maturing in bucket
- A negative gap means refinancing is needed. Cumulate gaps across buckets to see the survival period.
- Liquidity gap under stress
- Stress gap = Stressed cash outflows − Stressed cash inflows
- Compute per time bucket. A positive gap must be covered by the buffer and CFP actions.
- Survival horizon
- Survival horizon = number of days until cumulative net outflows exceed available liquid resources
- Include only assets that can be monetised in the stress, after haircuts.
- Counterbalancing capacity after haircuts
- Available liquidity = Σ (market value of asset × (1 − haircut))
- Apply haircuts to each asset class before adding.
- Funding shortfall to be covered by CFP
- CFP need = Cumulative net outflow − Buffer available
- If zero or negative, the buffer alone covers the horizon.
- Trigger logic
- Indicator ≥ (or ≤) threshold → escalate to the next tier
- Direction depends on the metric: higher is worse for outflow rates, lower is worse for buffer ratios.
- Encumbrance ratio
- Encumbrance ratio = Encumbered assets ÷ Total assets
- Some supervisors also include collateral received and re-used in the denominator and numerator. Follow the definition in the question.
- Collateral value after haircut
- Lending value = Market value × (1 − haircut)
- Use this to find the funding raised or the collateral still needed.
- Required collateral for a loan
- Market value required = Loan amount ÷ (1 − haircut)
- Haircut rises in stress, so required collateral rises.
- Unencumbered liquid buffer
- Usable buffer = Σ [Unencumbered market value × (1 − haircut)]
- Exclude any asset already pledged or legally trapped.
- Daily maximum intraday liquidity usage
- Max usage = largest net cumulative negative position during the day (net payments sent − received)
- A Basel monitoring tool. Compare it with available intraday liquidity.
- Intraday coverage check
- Available intraday liquidity − Peak net cumulative outflow ≥ 0
- A negative result means a shortfall; payments may be delayed or extra credit needed.
Quick revision
- Funding liquidity risk is the risk of being unable to meet obligations when due; market liquidity risk is the risk of being unable to sell assets without a large price impact.
- Liquidity risk appetite and limits are set by the board and senior management, with independent monitoring.
- A buffer should be sized against a stated stress scenario and survival horizon, not an average day.
- High-quality liquid assets are only useful if they are unencumbered and can be monetised quickly.
- Haircuts rise in stress, so the cash raised from collateral can fall just when you need it.
- Diversify funding by source, tenor, currency, counterparty and instrument; heavy reliance on short-term wholesale funding raises rollover risk.
- Maturity mismatches matter most when funding is short and assets are illiquid.
- A CFP sets out roles, triggers, actions and communication, and it should be tested regularly.
- Early warning indicators should be forward-looking and linked to specific CFP actions.
- Intraday liquidity needs depend on payment timing, so delays in receipts can force larger intraday borrowing.
- Rating downgrades can trigger collateral calls and withdrawal of funding, so consider them in stress design.
- Holding more liquidity lowers risk but costs earnings, so policy is a trade-off.
Common mistakes
- Treating funding and market liquidity as the same thing. Fix: Funding is about raising cash for liabilities. Market liquidity is about selling an asset at a fair price.
- Assuming a solvent bank cannot face a liquidity crisis. Fix: A bank with positive equity can fail if it cannot roll over funding. Liquidity and solvency are linked but different.
- Counting encumbered assets in the buffer. Fix: Only unencumbered assets count. Pledged collateral is not available to meet new outflows.
- Using full inflows instead of capping at 75% of outflows. Fix: Net outflows = outflows − min(inflows, 75% × outflows). Check the cap every time.
- Sizing the buffer to the average or expected scenario. Fix: Size to the most severe plausible scenario. The buffer must cover the peak cumulative need.
- Counting encumbered assets or using market value without haircuts. Fix: Exclude pledged assets and apply haircuts. Only the stressed, unencumbered value counts.
- Treating all deposits as equally stable. Fix: Separate insured retail from uninsured corporate and financial deposits. Stability depends on the depositor type and relationship.
- Assuming diversification removes funding risk in a systemic crisis. Fix: State that sources can fail together in market-wide stress. Diversification reduces, not removes, risk and must be paired with buffers.
- Treating the CFP as the same as the liquidity buffer. Fix: The buffer is the stock of liquid assets. The CFP is the plan for governance, triggers and actions, including how to use the buffer and what comes after it.
- Listing only internal indicators. Fix: Include market-based signals too, such as CDS spreads, share price, rating actions and repo terms. Good frameworks use both.
Exam tips
- Expect scenario stems asking you to classify the risk type, then to name the interaction. Label first, then choose.
- Governance questions test who does what. Memorise board, management, independent risk, audit roles.
- In LCR questions, check that inflows are netted and that you divide by net outflows, not gross.
- Be careful with absolutes such as always or never in options about liquidity and solvency.
- Read for encumbrance and currency clues. They are often the hidden reason a buffer fails.
- Always check the 75% inflow cap and the haircut before dividing.
- Memorise Level 1 (no haircut), Level 2A (15%) and the 40% and 15% caps.
- For strategy questions, pick the answer that balances cost against stress resilience, not the one that maximises either alone.
