In business, economics, or investment, market liquidity is an asset's ability to be sold without causing a significant movement in the price and with minimum loss of value. Money, or cash, is the most liquid asset, and can be used immediately to perform economic actions like buying, selling, paying debt, and meeting immediate wants and needs.
In bookkeeping and accounting, cash refers to current assets comprising currency or currency equivalents that can be accessed immediately or near immediately (as in the case of money market accounts). Cash is seen as a reserve for payments and as a way to meet financial obligations.
Cash
A business's cash account is how much currency it has on hand at a given time.
In banking, liquidity is the ability to meet obligations when they come due without incurring unacceptable losses. Managing liquidity is a daily process requiring bankers to monitor and project cash flows to ensure adequate liquidity is maintained. Maintaining a balance between short-term assets and short-term liabilities is critical. For an individual bank, clients' deposits are its primary liabilities (in the sense that the bank is meant to give back all client deposits on demand), whereas reserves and loans are its primary assets (in the sense that these loans are owed to the bank, not by the bank). The investment portfolio represents a smaller portion of assets, and serves as the primary source of liquidity. Investment securities can be liquidated to satisfy deposit withdrawals and increased loan demand. Banks have several additional options for generating liquidity, such as selling loans, borrowing from other banks, borrowing from a central bank, such as the U.S. Federal Reserve Bank, and raising additional capital. In a worst case scenario, depositors may demand their funds when the bank is unable to generate adequate cash without incurring substantial financial losses. In severe cases, this may result in a bank run. Most banks are subject to legally mandated requirements intended to help banks avoid a liquidity crisis.
