Overview

A liquid asset has some or all of the following features: It can be sold rapidly, with minimal loss of value, anytime within market hours. The essential characteristic of a liquid market is that there are always ready and willing buyers and sellers. It is similar to, but distinct from,

, which relates to the trade-off between quantity being sold and the price it can be sold for, rather than the liquidity trade-off between speed of sale and the price it can be sold for. A market may be considered both deep and liquid if there are ready and willing buyers and sellers in large quantities. An illiquid asset is an asset which is not readily salable (without a drastic price reduction, and sometimes not at any price) due to uncertainty about its value or the lack of a market in which it is regularly traded.

Effect on asset values

The market liquidity of assets affects their prices and expected returns. Theory and empirical evidence suggest that investors require higher return on assets with lower market liquidity to compensate them for the higher cost of trading these assets. That is, for an asset with given cash flow, the higher its market liquidity, the higher its price and the lower is its expected return. In addition, risk-averse investors require higher expected return if the asset's market-liquidity risk is greater. This risk involves the exposure of the asset return to shocks in overall market liquidity, the exposure of the asset's own liquidity to shocks in market liquidity and the effect of market return on the asset's own liquidity. Here too, the higher the liquidity risk, the higher the expected return on the asset or the lower is its price. One example of this is a comparison of assets with and without a liquid secondary market. The liquidity discount is the reduced promised yield or expected return for such assets, like the difference between newly issued U.S. Treasury bonds compared to off the run treasuries with the same term to maturity. Initial buyers know that other investors are less willing to buy off-the-run treasuries, so the newly issued bonds have a higher price (and hence lower yield).

Banking

In banking, liquidity is the ability to meet obligations when they come due without incurring unacceptable losses. Managing liquidity is a daily process requiring bankers to monitor and project cash flows to ensure adequate liquidity is maintained. Maintaining a balance between short-term assets and short-term liabilities is critical. For an individual bank, clients' deposits are its primary liabilities (in the sense that the bank is meant to give back all client deposits on demand), whereas reserves and loans are its primary

s (in the sense that these loans are owed to the bank, not by the bank). The investment portfolio represents a smaller portion of assets, and serves as the primary source of liquidity.

. Banks can generally maintain as much liquidity as desired because bank deposits are insured by governments in most developed countries. A lack of liquidity can be remedied by raising deposit rates and effectively marketing deposit products. However, an important measure of a bank's value and success is the cost of liquidity. A bank can attract significant liquid funds. Lower costs generate stronger profits, more stability, and more confidence among depositors, investors, and regulators.
