In business, economics or investment, market liquidity is a market's ability to facilitate the purchase or sale of an asset without causing drastic change in the asset's price. Equivalently, an asset's market liquidity (or simply "an asset's liquidity") describes the asset's ability to sell quickly without having to reduce its price to a significant degree. Liquidity is about how big the trade-off is between the speed of the sale and the price it can be sold for. In a liquid market, the trade-off is mild: selling quickly will not reduce the price much. In a relatively illiquid market, selling it quickly will require cutting its price by some amount.
