In a Truth Social post on Thursday, President Trump said he is instructing his “Representatives” to buy $200 billion in mortgage bonds, using what he states is $200 billion in cash sitting inside Fannie Mae and Freddie Mac.
Trump’s promise went right to the heart of what a lot of Americans want to hear right now: Lower bond yields, lower mortgage rates, lower monthly payments.
Byron Lazine broke down the announcement and its potential impact on today’s Hot Sheet. Here’s how it stacks up once you put it next to the bond market, the GSE balance sheets, and the housing data.
What Trump actually announced
Trump framed the policy as both an economic fix and a political victory. In his Truth Social post, he said Fannie Mae and Freddie Mac now hold enough cash to fund a massive mortgage bond buying program.
Trump stated:
“Because I chose not to sell Fannie Mae and Freddie Mac in my First Term, a truly great decision, and against the advice of the ‘experts,’ it is now worth many times that amount — AN ABSOLUTE FORTUNE — and has $200 BILLION DOLLARS IN CASH. Because of this, I am instructing my Representatives to BUY $200 BILLION DOLLARS IN MORTGAGE BONDS. This will drive Mortgage Rates DOWN, monthly payments DOWN, and make the cost of owning a home more affordable.”
Later in the day, FHFA Director Bill Pulte weighed in. On X, he wrote:
We are on it. Thanks to President Trump, Fannie and Freddie will be executing. https://t.co/WgRMNzWMpP

Pulte had also told CNBC earlier that Trump is expected to make a decision within the next month or two on a possible initial public offering of Fannie Mae and Freddie Mac, which adds another layer of complexity to how these GSEs could be used in 2026.
How mortgage bond buying affects rates
Mortgage rates move with bond markets. When demand for mortgage backed securities rises, prices go up and yields fall. That pulls mortgage rates lower.
The Federal Reserve has used this mechanism before. In a January 2026 Urban Institute report, Laurie Goodman and Jim Parrott explained how the system worked before and after the Great Financial Crisis.
“For years, Fannie Mae and Freddie Mac were the buyers of last resort in the market, stepping in to profit from widening spreads and, in doing so, putting a comforting outer bound on MBS volatility.
“Once they went into conservatorship, the government-sponsored enterprises (GSEs) were replaced in that role by the Federal Reserve…”
They also laid out the scale of the Fed’s intervention:
“The Federal Reserve bought $1.25 trillion in agency MBS between January 2009 and March 2010 and bought another $823 billion between 2012 and 2014.”
When markets froze in early 2020, mortgage spreads blew out. Goodman and Parrott noted:
“In February and early March 2020… mortgage spreads wider by 75 basis points…”
The Fed stepped in and bought more mortgage bonds in one month than the entire gross production of the securities, stabilizing rates. That stabilizing role ended in March 2022, when the Fed pivoted to quantitative tightening and began letting its mortgage bond portfolio run off.
Byron also referenced a Logan Mohtashami Tweet saying, “There are limits of the MBS plan, since spreads were almost back to normal, anyway.”
While the industry has been quick to discuss what this really means for mortgage rates, buyers seeing these headlines may decide to hold off on a home purchase as they wait for a massive rate drop.
Byron stated
“You’ve got to bring them back into a really basic scenario. ‘When rates drop, it’s because there are three levers that are being pulled: short-term bonds, long-term bonds, and mortgage-backed securities (MBS). When rates drop significantly, all three of those levers were to the extreme. It’s only two of the levers that are happening right now. The one that impacts rates the most—the long-term rates—hasn’t been pulled and only gets pulled in crisis moments.
“‘So, really, we’ve got to factor in, are we waiting for a crisis, or are we looking for the right home that fits into the right payment today?
“I’d also argue that if this were to happen, and you get short-term relief… who won the most in 2020-2021 when we financially engineered the rates? The first-movers.”
Why the mortgage spread is the real target
What Trump is trying to move is the mortgage spread, which measures the gap between the 10-year Treasury yield and the average 30-year fixed mortgage rate.
At its peak in June 2023, that spread hit 2.96 percentage points, or 296 basis points. The long-term average since 1972 is 1.76 percentage points, or 176 basis points. By December 2025, the spread had compressed to 2.05 percentage points, or 205 basis points.
The idea behind Trump’s $200 billion plan is to compress that gap by injecting more demand into the mortgage bond market. But that brings up the question of scale.
As of June 2025, there were $9.26 trillion in agency mortgage backed securities outstanding. That market is held across the global financial system:
- $3.00 trillion by banks and depositories
- $2.74 trillion by other domestic investors
- $2.14 trillion by the Federal Reserve
- $1.33 trillion by foreign buyers
- $0.06 trillion by Fannie Mae and Freddie Mac
In that context, $200 billion is meaningful, but it’s still a small slice of a $9.26 trillion market.
What Fannie and Freddie can realistically do
Fannie Mae and Freddie Mac have already been expanding their retained mortgage portfolios. Bloomberg data shows they added about $69 billion in the second half of 2025, or roughly $70 billion since May 2025.
They also face a hard legal cap of $450 billion combined, or $225 billion each.
John Burns Research and Consulting pointed out what that means for Trump’s plan. Research manager Alex Thomas wrote on X:
Fannie and Freddie have already added ~$70B to their retained mortgage portfolios since May of last year.
Adding another $200B would basically put the GSEs at their legal cap of $550B ($225B each). https://t.co/c7ZJJK5qNS pic.twitter.com/9bP78yZOCk

That constraint limits how much sustained pressure the GSEs can apply to a $9.26 trillion mortgage bond market.
What this means for housing in 2026
If you’re talking with buyers and sellers in 2026, the takeaway comes down to this:
- Watch inventory.
- Watch competition.
- And be ready to act quickly, before the crowd jumps in.
That was Byron’s parting advice.
“I think if you sit down and explain to a buyer the advantages of being an early mover, you can point to probably 5, 10, 15 stories in 2020-2021 in your market, first-mover advantage, and how much of a better deal they got….”
Speaking also of the president’s announced intention of banning institutional investors from buying single-family homes, Byron wrapped up with a long-term view of both strategies.
“Listen, brilliant politics… but both of these moves are not as impactful as maybe the headlines make them appear. I think we all want a short-term solution, in terms of rates. Still, when we talk about affordability long-term, not a fix.
“One argument could be made, ‘Let’s provide help short-term and work on the long-term solutions.’ I’d love to see that.”
