Financial institutions provide a service as intermediaries of the capital and debt markets. They are responsible for transferring funds from investors to companies, in need of those funds. The presence of financial institutions facilitates the flow of monies through the economy. To do so, savings accounts are pooled to mitigate the risk brought by individual account holders in order to provide funds for loans. Such is the primary means for depository institutions to develop revenue. Should the yield curve become inverse, firms in this arena will offer additional fee-generating services including securities underwriting, sales & trading, and prime brokerage.
