The government sponsore enterprises (GSEs) are a group of financial services corporations created by the United States Congress. Their function is to enhance the flow of credit to targeted sectors of the economy and to make those segments of the capital market more efficient and transparent. The desired effect of the GSEs is to enhance the availability and reduce the cost of credit to the targeted borrowing sectors: agriculture, home finance and education. Congress created the first GSE in 1916 with the creation of the Farm Credit System; it initiated GSEs in the home finance segment of the economy with the creation of the Federal Home Loan Banks in 1932; and it targeted education when it chartered Sallie Mae in 1972 (although Congress allowed Sallie Mae to relinquish its government sponsorship and become a fully private institution via legislation in 1995). The residential mortgage borrowing segment is by far the largest of the borrowing segments in which the GSEs operate. Together, the three mortgage finance GSEs (Fannie Mae, Freddie Mac and the 12 Federal Home Loan Banks) have several trillion dollars of on-balance sheet assets.
