Single Family Guarantee Fees Report

The Federal Housing Finance Agency (FHFA) today issued its annual report on single-family guarantee fees charged by Fannie Mae and Freddie Mac (the Enterprises). Guarantee fees are intended to cover the credit risk and other costs that the Enterprises incur when they acquire single-family loans from lenders. These costs include projected credit losses from borrower defaults over the life of the loans, administrative costs, and a return on capital. The report compares year-over-year 2020 to 2019 and provides statistics back to 2018. Significant findings of the report include: For all loan products combined, the average single-family guarantee fee in 2020 decreased 2 basis points to 54 basis points.  The upfront portion of the guarantee fee, which is based on the credit risk attributes (e.g., loan purpose, loan-to-value (LTV) ratio, and credit score), decreased 2 basis points to 11 basis points on average. The ongoing portion of the guarantee fee, which is based on the product type (fixed-rate or adjustable-rate, and loan term), remained unchanged at 43 basis points on average. The average guarantee fee in 2020 on 30-year and 15-year fixed rate loans remained unchanged at 58 basis points and 36 basis points, respectively. The fee on adjustable-rate mortgage (ARM) loans increased 1 basis point to 57 basis points. The Housing and Economic Recovery Act of 2008 requires FHFA to conduct ongoing studies of the guarantee fees charged by the Enterprises and to submit a report to Congress each year.

Credit Risk Transfer Progress Report

The credit risk transfer (CRT) programs at Fannie Mae and Freddie Mac (the Enterprises) wer​e established to reduce taxpayer exposure to risks arising from credit guarantees extended by the Enterprises through their normal courses of business. The Federal Housing Finance Agency (FHFA) initiated development of a CRT program in 2012 to reduce risk at the Enterprises during their conservatorships, and Fannie Mae and Freddie Mac began implementing their CRT programs in 2013. Under FHFA’s oversight through guidelines, instructions, strategic plans, and Scorecard objectives, the programs have since become a core part of the Enterprises’ single-family guarantee businesses, similar to how risk sharing with the private sector is an integral part of the Enterprises’ multifamily businesses. Using a range of different transaction structures, the Enterprises have transferred to private investors a substantial amount of credit risk assumed through the acquisition of single-family loans in targeted loan categories. The programs include or have included CRTs via capital markets issuances (both corporate debt and bankruptcy remote trust structures), insurance/reinsurance transactions, senior/subordinate transactions, and a variety of lender collateralized recourse transactions. The Enterprises continue to evaluate the scope of their CRT programs and innovate within the CRT market by employing different structures as part of their efforts to further reduce risk, all while using transactions that are economically sensible.​

Methodology for Determining Market Risk Scenarios

The FHFA methodology to construct a historically-based shock for a given interest rate is to measure the absolute change at each term point on the corresponding yield curve over a six-month horizon, and then impose that absolute change on the current measure of that yield curve.   However, because the current rate environment may differ significantly from the historical rate environment, imposing the historical shock on the current rate can result in a shock scenario that is implausible.  Implausible shock scenarios include any that contain negative values for interest rates, and those where the resulting spread between any two different interest rates is inconsistent with the historically observed spread.  To ensure that the resulting shock scenarios are plausible, FHFA uses a technique known as parsimonious factorization to represent each yield curve as a five-factor equation, and then applies measures of the shock made in parameter space to the current yield curve parameters to determine the shocked yield curve.  This approach facilitates a straightforward means to impose constraints on generating the shock scenario that ensure its plausibility.
