Definition
How quickly an asset converts to spendable cash without losing value. Savings accounts are highly liquid; home equity is not. Emergency money must stay liquid.
Why it matters
Net worth on paper does not pay a surprise bill; liquid money does. Matching each dollar's liquidity to when you might need it is what keeps wealthy-on-paper households out of credit card debt.
Example
A homeowner with $200,000 of equity but $500 in savings faces a $3,000 repair with a credit card, because equity takes weeks and fees to tap. $10,000 in a HYSA would have made the same repair a non-event.
