Fannie Mae and Freddie Mac: Privatization Debate Poses a Key Challenge for Bond Markets
The project to privatize the two American giants of mortgage financing is resurfacing in Washington. For investors in agency mortgage-backed securities (MBS), the central question remains the sustainability of the public guarantee that underpins the entire market.
A Symbolic Yet Complex Reform
Sixteen years after the 2008 financial crisis, the names Fannie Mae and Freddie Mac remain integral to the American mortgage system. These two Government-Sponsored Enterprises (GSEs) secure more than half of residential mortgage financing in the United States. Their federal conservatorship, following the subprime mortgage crisis, helped prevent a collapse in the housing and credit markets. The idea of reprivatizing them regularly resurfaces, but it seems to be gaining momentum now.
According to sources reported by Bloomberg and Reuters, Donald Trump recently met with several major investment banks to discuss their potential involvement in taking the two entities public. For John Kerschner, Nick Childs, and Thomas Polus, portfolio managers at Janus Henderson Investors, this prospect deserves careful attention without causing undue concern among bond investors. The primary challenge is financial.
When the US government bailed out the GSEs in 2008, it took a preferential stake in their capital through the Senior Preferred Stock Purchase Agreement (SPSPA). The current value of this position is around $340 billion, an amount the US Treasury has neither the intention to cancel nor the capacity to be repaid without an unprecedented market operation. Even at their current valuations, the GSEs would need to raise more than ten times the amount of Aramco's 2019 IPO ($29 billion) to repay the Treasury – a scenario deemed highly improbable by observers.
A Public Guarantee Essential for Market Stability
The true issue, therefore, lies not so much in the privatization itself, but in the fate of the public guarantee that accompanies the securities issued by Fannie Mae and Freddie Mac. Today, agency MBS are considered by the markets to be almost equivalent to government securities, precisely because of this implicit guarantee. Even before their conservatorship, investors already believed that the US government would intervene in the event of a default to preserve the stability of the housing market.
The US administration has confirmed that this guarantee would be maintained in the event of privatization, whether explicit or implicit. Without it, the consequences would be significant: an immediate increase in spreads on agency MBS, reduced liquidity, and higher mortgage rates for American households. According to Janus Henderson's analysis, complete privatization remains unrealistic in the short term. A gradual and partial process seems more likely: strengthening capital requirements, reducing the scope of GSEs' intervention, and maintaining public oversight.
Several levers are conceivable: lowering the ceilings on conforming loans, tightening credit criteria, and increasing guarantee fees applied to issuers. Ultimately, a combination of these measures could reduce the balance sheets of Fannie Mae and Freddie Mac while preserving their systemic role in housing finance.
Limited Impact on Securitized Markets
For institutional investors, the possibility of privatization does not undermine the structural attractiveness of agency MBS. These securities offer a yield/risk profile that is particularly sought after in a low-interest-rate environment, while benefiting from strong political support.
The guarantee, even if implicit, is the cornerstone of the system: it ensures the liquidity of the secondary market and helps stabilize the cost of real estate credit in the United States. In the short term, the prospect of privatization could even have a favorable technical effect. A gradual reduction in the net supply of securities, combined with increased capital requirements for GSEs, could support agency MBS spreads.
Investors are also anticipating strong demand from specialized bond funds, especially in a context where potential US interest rate cuts could occur by the end of the year. In summary, the renewed debate on the privatization of Fannie Mae and Freddie Mac highlights the tension between market logic and systemic stability imperatives. But for investors, the guiding principle remains unchanged: as long as the public guarantee exists, whether explicit or implicit, the agency MBS market will continue to act as a buffer in the global bond sphere.
