Liquidity measures how readily an asset can be sold at fair market value. Cash is the most liquid asset; real estate and collectibles are among the least liquid.
Liquidity Spectrum
- Most liquid: Cash, money market funds, Treasury bills
- Moderately liquid: Publicly traded stocks, bonds, ETFs
- Least liquid: Real estate, private equity, fine art
Why It Matters
Insufficient liquidity can force you to sell assets at a discount during emergencies. Financial advisors recommend keeping 3–6 months of expenses in liquid savings.
