A finance and accounting concept defining a method, measure, or process used to record activity and support financial decisions. It specifies how value, risk, or performance is measured or controlled through standardized rules and routines. It does not ensure correctness without reliable inputs, appropriate assumptions, and effective review and controls. It materially affects decisions and compliance by shaping how organizations allocate capital, report results, and manage exposure. The concept is generally stable, though standards, regulation, and tools evolve over time.

Principle

Liquidity risk comprises funding liquidity (ability to raise cash or refinance liabilities) and market liquidity (ability to transact without large price impact); the organizing principle is matching maturities, maintaining buffers and contingency plans while measuring market depth, bid-ask spreads and funding concentration.

Demonstration

A bank faces a sudden deposit run and cannot roll short-term wholesale funding without paying sharply higher rates; a fund attempting to sell a large block of an illiquid bond causes prices to gap down and realizes heavy losses.

Misapplication

Assuming a static cash buffer is sufficient without modelling contingent calls, margin requirements or correlated withdrawals; treating market liquidity and funding liquidity as interchangeable without stress scenarios.

Consequence

Proper liquidity risk management produces maintained liquidity buffers, diversified funding sources, haircuts and liquidity-adjusted valuation, contingency funding plans and limits on position sizes to avoid forced, loss-making sales.

Reversal

The reverse is a regime of abundant liquidity where asset sales do not move markets and funding is continuously available at stable spreads; misreading that environment as permanent can leave institutions exposed when conditions tighten.

Boundary

Covers both the balance-sheet (funding) and market ability to trade (market liquidity) for financial instruments and obligations; excludes solvency risk driven by long-term asset-liability mismatch or credit risk when default, not liquidity, is the primary driver, though these risks interact.

Semantic Tension

There is tension between defining liquidity narrowly as market microstructure (depth and spreads) versus broadly as any inability to meet obligations; another tension is between liquidity measured statically (buffers) and dynamically under stressed runs.

Synthesis

Liquidity risk is the potential inability to obtain cash or transact at reasonable prices when required; it is managed by matching maturities, holding buffers, diversifying funding and planning contingencies while testing stressed scenarios.
