Liquidity
✓ Last verified 14 Sep 2026
The short version
Liquidity is how quickly an asset can be converted to usable cash without losing significant value - cash itself is perfectly liquid; a house is not.
A savings account is highly liquid - money is available instantly. A fixed deposit is fairly liquid, with a small penalty for early withdrawal. Real estate and a 5-year lock-in investment are illiquid - converting them to cash takes time and sometimes forces a bad price. This is exactly why an emergency fund belongs in liquid instruments, not in your best-performing but hardest-to-exit investment: the whole point of the fund is being able to access it fast, at full value, precisely when you need it most.
