The Federal Loan Consolidation Program was created in 1986. In 1998, the United States Congress changed the interest rate to the aforementioned fixed rate weighted mean, effective February 1, 1999. Consolidation loans taken out before that date had a variable interest rate, determined by the individual FDLP loan origination center (e.g., in the case of a university, that university) or FFELP lender (e.g., a third party bank).
In 2005, the Government Accountability Office considered consolidating consolidation loans so that they were exclusively managed through the FDLP. Based on several assumptions about future variations in interest rates, the loan volume, the percentage of defaulters, cost estimates from the United States Department of Education, it concluded that while doing so would incur an additional cost of $46 million, caused by the higher administrative costs of the FDLP compared to the FFELP, this would be offset by a $3,100 million saving comprised in part of avoiding $2,500 million in subsidy costs. In 2008, turmoil in the financial and credit markets has led to the suspension of many loan consolidation programs, including Sallie Mae, Nelnet and Next Student.
