Key Concepts and Summary
Banks facilitate the use of money for transactions in the economy because people and firms can use bank accounts when selling or buying goods and services, when paying a worker or being paid, and when saving money or receiving a loan. In the financial capital market, banks are financial intermediaries; that is, they operate between savers who supply financial capital and borrowers who demand loans.
A balance sheet (sometimes called a T-account) is an accounting tool which lists assets in one column and liabilities in another column. The liabilities of a bank are its deposits. The assets of a bank include its loans, its ownership of bonds, and its reserves (which are not loaned out). The net worth of a bank is calculated by subtracting the bank’s liabilities from its assets. Banks run a risk of negative net worth if the value of their assets declines.
The value of assets can decline because of an unexpectedly high number of defaults on loans, or if interest rates rise and the bank suffers an asset-liability time mismatch in which the bank is receiving a low rate of interest on its long-term loans but must pay the currently higher market rate of interest to attract depositors. Banks can protect themselves against these risks by choosing to diversify their loans or to hold a greater proportion of their assets in bonds and reserves. If banks hold only a fraction of their deposits as reserves, then the process of banks’ lending money, those loans being re-deposited in banks, and the banks making additional loans will create money in the economy.
