Liquidity
How quickly an asset can be turned into cash at close to its full value, without forcing a discount.
What Liquidity means
Liquidity measures how easily you can convert something you own into spendable money. Cash is perfectly liquid; a checking or savings balance is nearly so; publicly traded stocks and ETFs settle within a day or two.
Illiquid assets are the opposite. Real estate, private business stakes, and collectibles can take months to sell, carry high transaction costs, and may only fetch full value if you can wait for the right buyer.
Retirement accounts occupy a middle ground: the investments inside are liquid, but reaching the money before age 59½ generally triggers taxes and a 10% penalty, which is a different kind of illiquidity.
The practical lesson is to match liquidity to time horizon. Money you might need within a year belongs somewhere you can reach it without selling at a bad moment.
