The Renewed Push for GSE Privatization
Recent discussions have brought the future of Fannie Mae and Freddie Mac (“F&F”) back into the spotlight. Comments from administration officials regarding the GSEs' role in a sovereign wealth fund, alongside reports of the White House considering steps toward ending their conservatorship, have fueled investor interest. The core idea posited is that selling the government's ownership stake in F&F through public equity markets could generate substantial proceeds for the U.S. Treasury.
Current Role and Market Dominance of Fannie Mae and Freddie Mac
Fannie Mae and Freddie Mac are central to the U.S. housing finance system, ensuring a stable supply of mortgage financing and promoting homeownership. They operate in the secondary mortgage market by purchasing mortgages from lenders, pooling them into mortgage-backed securities (MBS), and selling these securities to investors with a guarantee of payment.
Crucially, beyond their explicit guarantees, an implicit guarantee exists: markets widely believe the U.S. government would intervene to support the GSEs' obligations, preventing default. This perception allows GSE-issued securities to be viewed as nearly risk-free, enabling the GSEs to borrow at rates close to U.S. Treasuries and hold credit ratings comparable to the federal government. Currently, the GSEs back approximately 50% of all outstanding U.S. mortgage debt, amounting to $6.6 trillion. This government backing translates into lower mortgage rates for borrowers and supports the prevalence of the 30-year fixed-rate mortgage with prepayment rights, a unique feature of the U.S. market that provides payment stability and refinancing opportunities.
Key Borrower Advantages of the U.S. 30-Year Fixed-Rate Mortgage
LOWER MONTHLY PAYMENTS
Typically offers lower initial monthly payments
compared to shorter-term amortizing loans,
enhancing affordability
NO BALLOON PAYMENT
Fully amortizes over the term,
eliminating the risk of a
large lump-sum payment at maturity
INTEREST RATE STABILITY
Provides protection against
rising interest rates,
as the rate is fixed for the life of the loan
PAYMENT PREDICTABILITY
Ensures consistent principal and
interest payments,
aiding long-term household budgeting
REFINANCING FLEXIBILITY
Allows borrowers the option to refinance and
potentially secure a lower interest rate
if market rates decline
The Path to Privatization: Critical Hurdles
Successfully privatizing Fannie Mae and Freddie Mac involves overcoming several monumental obstacles:
Resolving the U.S. Treasury's Financial Stake
Following the 2008 financial crisis, the GSEs were placed into conservatorship, with the Treasury providing approximately $190 billion in capital support. In return, the Treasury received senior preferred shares and warrants to purchase up to 79.9% of the GSEs' common stock. While the GSEs have since paid $300 billion in dividends, recent amendments allow them to retain earnings to build capital. To compensate taxpayers for these forgone dividends, the U.S. Treasury Department reports that the liquidation preference on its senior preferred stock has increased, standing at $340 billion as of the third quarter of 2024. Addressing this substantial liquidation preference is a primary challenge, as it directly impacts the feasibility of raising new private capital and the returns available to potential new shareholders. The political viability of the Treasury forgiving a significant portion of this $340 billion claim is also questionable.
The Future of the Government Guarantee
The nature of any future government support is paramount.
Explicit Guarantee
This would likely require Congressional action and involve a fee paid to the Treasury for assuming credit risk, similar to Ginnie Mae. This could increase costs for borrowers but might maintain market stability.
Implicit Guarantee
If conservatorship ends without an explicit guarantee, markets might still assume some level of government backstop. However, this uncertainty would likely increase borrowing costs and volatility for the GSEs. Rating agencies like Moody's have indicated that a reduction in government support could lead to a one- to three-notch downgrade in the GSEs long-term debt ratings. Fitch Ratings noted that without the Preferred Stock Purchase Agreements (PSPAs) or equivalent support, GSE ratings would be evaluated on a standalone basis, considering their monoline business models.
No Guarantee
This scenario would likely lead to the most significant increase in funding costs and market disruption. The US Department of Housing and Urvan Development (“HUD”) report from 1996, while dated, suggested that GSE borrowing costs could rise by 30-75 basis points without their agency status.
Currently, fixed income markets appear to price in a continued government guarantee, evidenced by narrow agency MBS spreads over Treasuries. A change in this assumption could cause significant spread widening.
Recapitalization Needs
Despite recent earnings retention, Fannie Mae and Freddie Mac remain significantly undercapitalized. As of September 30, 2024, their combined net worth was $147 billion, far below the FHFA's Enterprise Regulatory Capital Framework (ERCF) requirement of $328 billion (Fannie Mae: $187 billion, Freddie Mac: $141 billion). This leaves a regulatory capital shortfall of $181 billion. Building this capital organically through retained earnings, assuming $25 billion in combined annual earnings, could take approximately seven years. An IPO might accelerate this, but the sheer scale of capital needed, on top of resolving Treasury's stake of $340 billion, presents a formidable challenge. The private capital needed to satisfy both the regulatory capital shortfall and the U.S. Treasury’s stake is staggering (Figure 1). Furthermore, fully private entities would likely face market demands for even higher capital levels to compensate for the absence of a government backstop.

Potential Market and Economic Ramifications
Privatization, especially without a robust government guarantee, could send shockwaves through the financial system:
Mortgage Rates and Housing Affordability
A primary concern is the potential for wider mortgage spreads and increased mortgage rates, negatively impacting consumers and exacerbating housing affordability challenges. While the exact impact is debated, the 1996 HUD report estimated that conforming mortgage rates could be 25-40 basis points higher in a privatized scenario without the GSEs' funding advantage. More recent analyses suggest GSE unsecured funding costs could rise 40-65 bps if rated AA-A without an explicit guarantee. Increased borrowing costs for the GSEs would likely be passed on to homeowners. (See table below)
Impact on Affordable Housing and Underserved Communities
The GSEs currently operate under housing goals mandated to support low- and moderate-income families and underserved areas. Privatization could jeopardize these efforts. The HUD report raised concerns that fully privatized GSEs might:
The Agency MBS and TBA Markets
The To-Be-Announced (TBA) market, with an average daily trading volume of $290 billion in 2024, is critical for mortgage market liquidity and risk management.
UMBS Integrity
Privatizing Fannie Mae and Freddie Mac as separate, competing entities could threaten the viability of the Uniform Mortgage-Backed Security (UMBS), potentially fragmenting the TBA market and reducing liquidity.
Spread Widening and Volatility
Uncertainty about guarantees could lead to higher and more volatile spreads on agency MBS.
Bank Holdings
If GSE guarantees are removed or altered, the risk-weighting and liquidity coverage ratio treatment of agency MBS for banks could change, reducing their appeal. Furthermore, the removal of the GSEs exemption from single-counterparty limits could force large banks to reduce their holdings, shrinking TBA market participation and liquidity.
Foreign Investment
International investors, key holders of agency MBS, might reassess the risk profile of GSE debt if it's no longer seen as a close proxy for U.S. government obligations, potentially shifting demand to Ginnie Mae MBS.
Impact on Financial Institutions
Banks
May become more reluctant to hold significant mortgage portfolios due to negative convexity and lessons from past interest rate cycles. They might prefer originating and selling mortgages in structured product formats. Higher capital charges for MBS could further reduce bank demand.
Non-Banks
While non-bank mortgage originators might expand to fill gaps left by GSEs, their capacity to absorb unguaranteed mortgage risk at scale is uncertain.
GSEs’ Retained Portfolios
Fannie Mae and Freddie Mac hold substantial retained portfolios of MBS (over $95 billion for Fannie Mae and over $100 billion for Freddie Mac as of the draft). If these portfolios are reduced significantly as part of a scaled-back GSE role, it could lead to lower prices and higher yields for agency MBS as a major source of demand diminishes. (See Figure 2)
Monetary Policy Considerations
The efficacy of monetary policy could be affected. If the agency MBS market becomes less liquid or stable, it could diminish a key channel for the Federal Reserve's policy implementation, particularly during periods of market stress.

Strategic Alternatives
One alternative discussed is a merger of Fannie Mae and Freddie Mac, potentially yielding administrative efficiencies. However, this would not resolve the fundamental questions of capital and guarantees and could impact perceived differences in their securities' performance. The public utility model has also been mentioned as a theoretical alternative structure.
Key Takeaways for Investors
We believe the path to full privatization is fraught with substantial challenges, making a near-term resolution unlikely. The primary hurdles remain the significant capital shortfall, the resolution of the Treasury's large financial stake, and the uncertain future of the government guarantee. Should privatization proceed, particularly without a strong government backstop, the implications for mortgage rates, housing affordability, and financial market stability could be severe. Investors should monitor:
Ultimately, any significant reform requires careful navigation to balance the objectives of reducing government footprint with maintaining a stable and accessible housing finance system. The current structure, while imperfect, has supported a relatively stable mortgage market.
