Liquidity risk
What is Liquidity risk?
Liquidity risk is the risk that an investment cannot be sold, financed, or converted to cash when needed without delay or a material price concession.
Why liquidity risk matters
A portfolio can be solvent on paper yet unable to meet redemptions, collateral calls, or spending needs without selling assets at distressed prices. Liquidity often appears abundant in calm markets and disappears when many investors want to trade in the same direction. The resulting price impact can turn a temporary cash need into a permanent investment loss.
Two forms of liquidity risk
Market liquidity risk concerns the ability to trade an asset near its observed price. Funding liquidity risk concerns access to cash or financing. The two interact when falling prices trigger margin calls, forcing sales that further reduce prices. Asset managers compare asset liquidity with liability terms, expected cash flows, and the speed at which investors can redeem.
Example
A fund offers daily redemptions but holds thinly traded credit. Normal transaction data suggest positions can be sold over several days. During stress, spreads widen, dealer capacity falls, and redemption requests rise. Meeting cash needs may require selling the most liquid holdings first, leaving remaining investors with a less liquid and potentially riskier portfolio.
How to measure it
Measures include bid-ask spread, trading volume, market depth, price impact, days to liquidate, redemption coverage, cash buffers, and stressed liquidation cost. Position size should be compared with realistic market capacity rather than average volume alone. Analysis should account for settlement, notice periods, gates, collateral eligibility, and currency-specific cash needs.
Limitations
Observed volume can overstate available capacity because the portfolio's own sale changes the market. Different holdings may become illiquid simultaneously, and historical stress may not represent the next event. Reported fund liquidity buckets depend on assumptions. A model cannot guarantee execution, so governance and contingency arrangements remain necessary.
Practical checklist
Map contractual cash outflows by date and currency, then compare them with cash and assets that can be monetized under normal and severe assumptions. Apply concentration and price-impact adjustments, test redemption waves and margin calls, and identify collateral substitutions. Establish escalation triggers, lines of authority, and a documented liquidity contingency plan before stress occurs.
