AEI Panel: GSEs Have Never Paid for Their Guarantee

Why It Matters

The guarantee’s unpaid cost represents a hidden fiscal exposure, and its future shape will affect mortgage rates, housing affordability, and taxpayer risk.

Key Takeaways

• Implicit guarantee never cost taxpayers a penny
• Guarantee valued at $9 billion, 25% pretax profit
• Shrinking guarantee could raise GSE capital requirements
• Investors push for repayment of senior preferred shares
• Abrupt guarantee removal risks mortgage market stability

Pulse Analysis

The implicit guarantee that underpins Fannie Mae and Freddie Mac has been a cornerstone of the U.S. mortgage market since the 2008 conservatorship, yet it remains an unpaid liability for taxpayers. While the Trump administration has signaled continuity of the guarantee to keep mortgage rates low, experts at an AEI panel warned that the guarantee’s true cost—estimated at $9 billion in 2024, or about a quarter of the GSEs’ pretax profits—has never been recouped. This hidden expense raises questions about fiscal responsibility and the long‑term sustainability of a market that depends on government‑backed financing.

Investors who hold senior preferred‑stock warrants, set to expire in 2028, are now demanding that the government honor repayment and allow the GSEs to exit conservatorship via a share offering. Their push reflects a broader tension between private capital seeking returns and public policy aimed at protecting homeowners. Meanwhile, the guarantee’s implicit nature distorts market competition, as it effectively subsidizes mortgage financing and shields the GSEs from risk, prompting calls for a risk‑based pricing model similar to FDIC insurance premiums.

Policy makers face a delicate balancing act: scaling back the guarantee could reduce taxpayer exposure but would likely require the GSEs to boost capital buffers, potentially raising mortgage rates and tightening credit. Proposals include narrowing the guarantee to primary home purchases, shedding refinancing and investor‑mortgage exposure, and instituting a fee structure that mirrors private insurance models. Such reforms aim to preserve market stability while addressing the fiscal gap, but they will inevitably spark debate among lenders, investors, and housing advocates about the optimal path toward a sustainable, taxpayer‑neutral mortgage finance system.
