Student Loan ABS and Government Guarantees

Student loan asset-backed securities (SLABS) come in two families that behave nothing alike. FFELP loans (originated under the old Federal Family Education Loan Program, discontinued in 2010) carry a US government guarantee covering most of the principal if a borrower defaults. Private student loans carry no such backstop, recovery depends entirely on the borrower's (and any cosigner's) ability and willingness to pay.

Why the guarantee changes the analysis

For FFELP paper, the dominant questions are not "will this borrower default", the guarantee covers 97–100% of principal on a default anyway, but timing and extension risk: income-driven repayment plans, deferments, and forbearances can stretch a loan's life for a decade or more, which hurts a bond priced to a shorter expected maturity even though credit losses stay low. For private student loan ABS, the analysis looks like any other consumer credit deal: cohort default curves by school and degree type, cosigner release provisions, and recovery rates on a loan that (unlike a mortgage) has no physical collateral behind it, a defaulted borrower simply owes an unsecured debt.

A ratings analyst or ABS investor pulling up a shelf of student loan bonds has to check which regime applies before any spread-versus-risk comparison is meaningful: a wide-looking spread on FFELP paper is usually compensation for extension risk, while the same spread on private paper is compensation for real credit loss.
