The government-sponsored enterprise retained a combination of loans and mortgage-backed securities totaling nearly $168.74 billion in March, up considerably from the previous month's $150.39 billion. Freddie Mac, in contrast, only reported a rise to $139.76 billion from $138.57 billion. "Fannie Mae increased its retained portfolio by approximately $18.3 billion in March, the largest monthly addition since 2009," Satish Mansukhani, a managing director at Rithm, and Alan Wynne, a vice president, wrote in a recent report. The $308.5 billion in both retained portfolios combined that month also marked a high not seen since early 2021, they added. Given that Freddie Mac was more aggressive than its counterpart for much of the past year, the March activity establishes that there's a different trend at play in 2026. "These reports showed considerable differences in the pace of agency MBS growth at the two Fs," former technology executive Bill McBride noted in his CalculatedRisk blog. McBride attributed the insight to Tom Lawler, a housing economist. McBride is known for being among the first wave of pundits to foresee the housing bubble that forced the GSEs into government conservatorship in 2008, and Lawler was a senior vice president at Fannie in the pre-crisis era. The blog indicates that the driver of the disparity between the two GSEs' retained portfolios is unclear, but suggested it could be related to growing market-value sensitivity of the retained portfolios to rate swings. Models suggest that as of the end of March, Freddie would take more losses in response to a theoretical 50 basis-point jump in rates than Fannie, according to the blog. ## Retained portfolios and "IPO" prospects Some analysts like those at Keefe, Bruyette & Woods have viewed retained portfolio expansion as being conducive to a plan to stage the first new offering of GSE stock in some time because it is accretive to earnings. Combined with the expansion of the investments portfolio, growth in the retained one was the main driver of net interest-income growth fueling Freddie Mac's first-quarter gain. However, Fannie Mae reported some investment losses on MBS purchases for the retained portfolio. Retained portfolio growth may help build capital that could support interest in an "initial public offering" of enterprise shares, but it adds more risk-weighted assets that complicate the process, other analysts at Mizuho recently pointed out. Fannie's net worth would already exceed standards if the enterprises were to reduce their current requirements to 2.5% of risk weighted assets, according to a recent Mizuho report. Freddie could meet that standard after a year of earnings retention. However, Wedbush analysts call Freddie as the more favorably positioned of the two when it comes to rebuilding common equity, which is a measure that may draw more focus from investors. Both Wedbush and Mizuho have forecast that rebuilding capital could take several years under current standards. Mizuho recently put 30% odds on a "fast exit" from conservatorship with lower capital standards that could accommodate a secondary stock offering for Fannie. It put 20% odds on the same happening at Freddie. Trump administration officials have shown interest in a new offering for 2.5%-5% of Fannie and Freddie's shares in the past, but there have been fewer policymaker statements about the plan recently and some analysts say it will likely be on hold until after the midterms. ### 相关股票 - [FNMA.US](https://longbridge.com/zh-CN/quote/FNMA.US.md) - [FMCC.US](https://longbridge.com/zh-CN/quote/FMCC.US.md) - [RITM.US](https://longbridge.com/zh-CN/quote/RITM.US.md) - [MFG.US](https://longbridge.com/zh-CN/quote/MFG.US.md) - [8411.JP](https://longbridge.com/zh-CN/quote/8411.JP.md) - [RITM-B.US](https://longbridge.com/zh-CN/quote/RITM-B.US.md) - [RITM-A.US](https://longbridge.com/zh-CN/quote/RITM-A.US.md) - [RITM-C.US](https://longbridge.com/zh-CN/quote/RITM-C.US.md) - [RITM-F.US](https://longbridge.com/zh-CN/quote/RITM-F.US.md) - [RITM-E.US](https://longbridge.com/zh-CN/quote/RITM-E.US.md) - [RITM-D.US](https://longbridge.com/zh-CN/quote/RITM-D.US.md) ## 相关资讯与研究 - [房地美｜8-K：2026 财年 Q1 营收 61.33 亿美元](https://longbridge.com/zh-CN/news/284765354.md) - [比尔·阿克曼建议投资者别再担忧伊朗战争，并买入这两只股票](https://longbridge.com/zh-CN/news/281641613.md) - [背景真假不重要？特朗普再凭 “头条” 扭转美股颓势](https://longbridge.com/zh-CN/news/287178611.md) - [对冲基金大佬高喊 “十倍机会” ，房利美、房地美盘中飙升 41% 和 34%](https://longbridge.com/zh-CN/news/281045197.md) - [房利美与房地美响应特朗普 2000 亿美元指令，加大 MBS 购买力度](https://longbridge.com/zh-CN/news/280168548.md)
