Liquidity

Plain-language definition Crypto glossary

Key takeaways

Liquidity is how easily an asset can be bought or sold without significantly moving its price, with a highly liquid market having plenty of buyers and sellers close together.
On an order-book exchange liquidity shows up as the depth of buy and sell orders around the current price, while in DeFi it is supplied to pools that trades are priced against.
When liquidity is thin, even a modest order can cause large slippage, so low-liquidity assets can be difficult to sell at the displayed price.

Definition

Liquidity describes how easily an asset can be bought or sold at its current market price without moving that price significantly. A liquid market has many buyers and sellers active at once and tight spreads between bid and ask prices; an illiquid market has few participants, wider spreads, and prices that can swing sharply on a single large order.

Why it matters

Liquidity affects how reliable a quoted price actually is. In a thin market, the price you see may not be the price you get once you try to execute a meaningful trade, and exiting a large position can itself push the price against you. This is one reason a high market cap does not automatically mean an asset is easy to trade in size.

Example

Major coins like Bitcoin and Ethereum typically trade on many exchanges with deep order books, while small-cap tokens can have most of their volume concentrated on one venue. Compare trading volume across assets on our markets page.

FAQ

Frequently asked questions

Why does liquidity matter when trading?

Liquidity affects the real cost of trading, the reliability of a quoted price, and how safely you can enter or exit a position. In a thin market even a modest order can move the price against you, so a displayed price may not be the price you actually get.

What is slippage and how is it related to liquidity?

Slippage is when a trade fills at a worse price than expected. It tends to happen when liquidity is thin, because there are not enough nearby orders or pool depth to absorb your trade without moving the price.

How is liquidity provided in DeFi?

In DeFi, users supply liquidity to pools by depositing pairs of tokens, and trades are priced against those pools. The more liquidity a pool holds, the less a given trade moves the price, which reduces slippage for traders.
