Liquidity refers to a state where something is in liquid form, like water. It can also refer to having cash or access to cash. Liquidity means things are flowing.
Although liquidity refers to…surprise! being a liquid, it’s usually used in a financial sense. Financially, liquidity refers to having access to cash or things you can sell and turn into cash. In other words, you have good cash flow. Liquidity can also apply to any situation that is marked by fluidity or runniness. You hope your new swimming pool is in a state of liquidity, and that you have enough financial liquidity to pay for it!
