Funding liquidity is the ability to meet cash obligations when due. Operational liquidity supports the routine settlement of customer and bank transactions. Strategic liquidity preserves the ability to pursue longer-term business plans, such as lending growth or an acquisition. Contingent liquidity is needed when uncertain events create additional demands, such as commitment drawdowns or margin calls. Restricted liquidity exists on the balance sheet but cannot be freely deployed where needed because of legal, regulatory, contractual or operational constraints.
These categories can overlap. A derivatives margin call creates a contingent funding demand with an operational deadline. Cash at a foreign subsidiary may appear in consolidated resources while being restricted from transfer to the parent. The relevant question is whether the resource can meet the particular payment in the required currency, entity and time window.
A stress test translates adverse events into dated cash demands and resource constraints. Define the perimeter first: entities, currencies, business lines, on-balance-sheet positions, commitments, collateral and payment systems. Use horizons suited to the decisions, from intraday survival to longer-term funding adjustment.
Common mistakes
- Calling every liquid asset deployable. Encumbrance, currency, entity restrictions and settlement delays can prevent use.
- Treating scenario inputs as universal rules. Runoff, drawdown and cushion assumptions must be specified and justified.
- Using final net flow as peak need. Example 2 ends in surplus but cannot meet the first day's payments without action.
Bottom line
- Liquidity needs differ by purpose, time, currency and legal entity.
- Stress tests combine cash demands with realistic resource constraints and risk interactions.
- Buffers must be usable under the scenario, with encumbrance and execution costs recognized.
- Reports show the first deficit, peak need, actions and residual exposure.
Exam shortcut
Read the first negative cumulative bucket before the final total. For each proposed source, check amount, access conditions and arrival time. Reject an action that solves the right amount on the wrong date.
