What is Liquidity?
Quick definition
How quickly an asset can be converted to cash without losing value. Cash is the most liquid asset; real estate is the least.
Full explanation
Liquidity measures how fast and at what cost an asset can be turned into cash. Cash itself is perfectly liquid. Stocks in major companies are highly liquid (sell in seconds). Real estate is illiquid — selling a house takes 30–90 days and 5–8% in transaction costs. In emergencies, illiquid assets can be a problem: people who are "house rich, cash poor" cannot easily access their equity. The liquidity premium is the extra return investors demand for locking up money in illiquid assets. Emergency funds should always be held in liquid accounts (checking, savings, money market).
