A '''liquid asset''' is an asset that can be converted into cash quickly, with minimal loss of value and low transaction costs. Liquidity is a matter of degree, and assets are often ranked along a spectrum from highly liquid, such as cash and bank deposits, to illiquid, such as real estate and private equity. Liquidity is important for households managing unexpected expenses, for firms meeting working capital needs, and for financial institutions managing depositor withdrawals and regulatory requirements.

== Dimensions of liquidity ==

Liquidity has several dimensions. '''Market liquidity''' refers to the ease of trading an asset without moving its price, and it depends on the depth of the market, the number of participants, and the presence of market makers. '''Funding liquidity''' refers to the ability of an institution to raise cash, either by selling assets or by borrowing, and it is closely linked to market liquidity, since assets are easier to sell in liquid markets.

A related concept is the bid-ask spread, which measures the cost of transacting. Narrow spreads indicate high liquidity. Other indicators include trading volume, market depth, and the time required to execute a trade. Assets can become illiquid suddenly, especially under stress, when market makers withdraw and buyers disappear, a phenomenon observed in several markets during the 2008 crisis and the pandemic shock.

== Money and near-money ==

Economists distinguish between money and near-money. Narrow measures of money include currency and demand deposits, which are directly usable for transactions. Broader measures include savings deposits, money market instruments, and short-term securities, which can be converted into money quickly but are not directly used for payment. The monetary aggregates used by central banks are constructed to reflect these degrees of liquidity.

Money market instruments, such as Treasury bills, commercial paper, and certificates of deposit, are examples of highly liquid assets that yield a return. They play a central role in the financial system, providing short-term funding and a place to hold cash balances efficiently.

== Liquidity management ==

Households and firms manage liquidity by holding a buffer of liquid assets to meet unexpected needs and to avoid the cost of raising funds in a hurry. The theory of the precautionary demand for money explains why agents hold liquid balances even when higher-yielding assets are available. Financial institutions manage liquidity to meet withdrawals and regulatory requirements, such as the liquidity coverage ratio introduced after the global financial crisis, which requires banks to hold sufficient high-quality liquid assets to survive a period of stress.

Central banks provide liquidity to the financial system through lending facilities and open market operations, acting as the lender of last resort during crises. The availability of central bank liquidity can substitute for private liquidity in stressed conditions, though it also creates moral hazard.

== Liquidity and asset pricing ==

Liquidity affects asset prices. Illiquid assets must offer higher expected returns to compensate holders for the difficulty of selling them, a phenomenon known as the liquidity premium. During crises, liquidity evaporates, and the premium spikes, causing sharp price declines. The interaction between funding and market liquidity can create a vicious cycle, in which falling asset prices trigger margin calls, forcing sales that depress prices further.

These dynamics have been central to understanding financial instability and to the design of regulation. The recognition that liquidity can disappear precisely when it is needed most has led to requirements for liquid asset buffers, to central bank facilities that provide liquidity against a broad range of collateral, and to international standards for liquidity risk management.

== Liquidity and financial stability ==

Liquidity is central to financial stability. Financial institutions rely on liquid assets to meet withdrawals and to absorb shocks, and the composition and quality of those assets matter for resilience. The global financial crisis demonstrated that assets assumed to be liquid could become illiquid under stress, and that the failure to manage liquidity had systemic consequences, as institutions were forced to sell assets at fire-sale prices.

Regulatory frameworks have since incorporated liquidity requirements, including the liquidity coverage ratio, which requires banks to hold sufficient high-quality liquid assets to survive a severe stress scenario, and the net stable funding ratio, which limits reliance on short-term funding. These requirements aim to make the financial system more resilient, though they can also create incentives for institutions to hold similar assets, potentially amplifying stress if those assets become illiquid simultaneously.

== Liquidity in asset markets ==

Liquidity varies across asset classes and over time. Government bonds of major economies are among the most liquid assets, while corporate bonds, emerging-market debt, and real estate are less liquid. Liquidity tends to decline in periods of stress, when market makers withdraw and risk appetite falls, and it can disappear entirely in extreme conditions, as seen in some structured credit markets during the crisis.

The decline in liquidity under stress has motivated research on its drivers and on the role of market structure. The increasing importance of electronic trading and of principal trading firms has changed the provision of liquidity, with implications for resilience. Understanding the dynamics of liquidity is important for investors, for regulators, and for central banks that may need to provide liquidity in times of stress.

== Liquidity and portfolio choice ==

Portfolio choice involves a trade-off between return and liquidity. Liquid assets typically offer lower returns, because investors value the option to convert them to cash quickly. Illiquid assets offer higher expected returns but carry the risk that they cannot be sold when needed, or can be sold only at a discount. The liquidity premium compensates investors for bearing this risk.

Investors manage this trade-off by holding a mix of liquid and illiquid assets, tailored to their needs and horizons. Pension funds and insurers, with long-dated liabilities, can hold more illiquid assets, while money market funds and banks, with shorter horizons and potential withdrawals, need more liquid portfolios. Regulation and accounting rules also influence choices by penalising or rewarding certain asset types.
