when an otherwise solvent business does not have the liquid assets in cash or other highly marketable assets necessary to meet its short term obligations it faces a liquidity problem obligations can include repaying loans paying its ongoing operational bills and paying its employees 
these business may have enough value in total assets to meet all these in the long run but if it does not have enough cash to pay them as they come due then it will default and could eventually enter bankruptcy as creditors demand repayment the root of the problem is usually a mismatch between the maturities of investments the business has made and the liabilities the business has incurred in order to finance its investments this produces a cash flow problem where the anticipated revenue from the business various projects does not arrive soon enough or in sufficient volume to make payments toward the corresponding financing for businesses this type of cash flow problem can be entirely avoided by the business choosing investment projects whose expected revenue matches the repayment plans for any related financing well enough to avoid any missed payments alternatively the business can try to match maturities on an ongoing basis by taking on additional short term debt from lenders or maintaining a sufficient self financed reserve of liquid assets on hand in effect relying on equity holders to make payments as they come due many businesses do this by relying on short term loans to meet business needs often this financing is structured for less than a year and can help a company meet payroll and other demands if a business investments and debt are mismatched in maturity additional short term financing is not available and self financed reserves are not sufficient then the business will either need to sell other assets to generate cash known as liquidating assets or face default when the company faces a shortage of liquidity and if the liquidity problem cannot not solved by liquidating sufficient assets to meet its obligations the company must declare bankruptcy banks and financial institutions are particularly vulnerable to these kind of liquidity problems because much of their revenue is generated by lending long term on loans for home mortgages or capital investments and borrowing short term from depositors accounts maturity mismatching is a normal and inherent part of the business model of most financial institutions and so they are usually in a continual position of needing to secure funds to meet immediate obligations either through additional short term debt self financed reserves or liquidating long term assets 1liquidity crisisindividual financial institutions are not the only ones who can have a liquidity problem when many financial institutions experience a simultaneous shortage of liquidity and draw down their self financed reserves seek additional short term debt from credit markets or try to sell off assets to generate cash a liquidity crisis can occur interest rates rise minimum required reserve limits become a binding constraint and assets fall in value or become unsaleable as everyone tries to sell at once the acute need for liquidity across institutions becomes a mutually self reinforcing positive feedback loop that can spread to impact institutions and businesses that were not initially facing any liquidity problem on their own entire countries and their economies can become engulfed in this situation for the economy as a whole a liquidity crisis means that the two main sources of liquidity in the economy banks loans and the commercial paper market become suddenly scarce banks reduce the number of loans they make or stop making loans altogether because so many non financial companies rely on these loans to meet their short term obligations this lack of lending has a ripple effect throughout the economy in a trickle down effect the lack of funds impacts a plethora of companies which in turn affects individuals employed by those firms a liquidity crisis can unfold in in response to a specific economic shock or as a feature of a normal business cycle for example during the financial crisis of the great recession many banks and non bank institutions had significant portions of their cash come from short term funds that were put towards financing long term mortgages when short term interest rates rose and real estate prices collapsed such arrangements forced a liquidity crisis 2a negative shock to economic expectations might drive the deposit holders with a bank or banks to make sudden large withdrawals if not their entire accounts this may be due to concerns about the stability of the specific institution or broader economic influences the account holder may see a need to have cash in hand immediately perhaps if widespread economic declines are feared such activity can leave banks deficient in cash and unable to cover all registered accounts
