Market Liquidity — What It Is and Why It Matters
Liquidity is the ability to quickly buy or sell assets without significant impact on price. Learn how liquidity affects your investments.
Definition
Market liquidity is the ability to quickly buy or sell assets at a price close to the current market price, without significantly affecting that price.
Liquid vs illiquid assets
| Asset | Liquidity | Sale time |
|---|---|---|
| Cash | Highest | Immediately |
| Blue chip stocks (e.g., Apple) | Very high | Seconds |
| S&P 500 ETF | Very high | Seconds |
| Treasury bonds | High | Minutes-hours |
| Small company stocks | Medium | Minutes-days |
| Real estate | Low | Weeks-months |
| Art | Very low | Months-years |
How to measure liquidity?
Bid-ask spread
The difference between the best buy price (bid) and best sell price (ask). The smaller the spread, the higher the liquidity.
- VUAA on Xetra: spread 0.02-0.05% → very liquid
- Small company on WSE (GPW): spread 1-3% → low liquidity
Trading volume
Number of transactions or daily trading value. Higher volume = easier to buy and sell.
Market depth (order book)
How many orders are waiting for execution at different prices. Deep market = large orders don't move prices.
Why is liquidity important?
- Transaction costs: In an illiquid market you pay higher spreads — this is a hidden cost
- Exit speed: In a crisis you want to be able to quickly sell assets
- Price stability: Liquid markets have smaller price fluctuations
- Order execution: In a liquid market your order will be executed at the expected price
Liquidity risk
Liquidity risk is a situation where you cannot sell assets when you want — or you can, but at a significantly lower price. It particularly affects:
- Investors in small companies (small caps)
- Property owners during a crisis
- Corporate bonds during market panic
