What liquidity means in practice
An asset is considered liquid when two conditions are broadly met: it can be sold quickly, and selling it does not force a meaningful discount to its recent market value. Cash is the reference point because it needs no conversion at all. Other assets sit along a spectrum. Widely traded instruments with many active buyers and sellers tend to be closer to the liquid end, while assets that require finding a specific buyer, completing paperwork, or waiting through settlement or notice periods sit further away. Liquidity is not fixed. The same asset can be easy to sell in calm markets and hard to sell during stress, so careful investors think about liquidity under normal conditions and under pressure.
- Liquidity combines speed of sale and stability of price when selling.
- Cash and cash-like holdings are the usual reference point for comparison.
- Liquidity can change with market conditions, so it should be reviewed over time.
