Trump Mortgage Rate Reform: Lower Home Loan Costs for Buyers

President Trump directed Fannie Mae and Freddie Mac to buy $200 billion in mortgage bonds, aiming to ease borrowing costs for homebuyers sidelined by high rates.

“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,” Trump wrote on Truth Social.

Federal Housing Finance Agency Director William Pulte confirmed that Fannie Mae and Freddie Mac will carry out the bond purchases.

Markets reacted immediately, with the 30-year mortgage rate falling to nearly 6% on Friday its lowest level since early 2023, according to Mortgage News Daily.

When you secure a mortgage, lenders often sell it to Fannie Mae or Freddie Mac. These agencies then package the loans into mortgage-backed securities and sell them to investors, a process that keeps cash circulating to lenders and helps stabilize mortgage rates.

By shifting to have Fannie Mae and Freddie Mac directly purchase these bonds, the goal is to reduce mortgage rates further, making homeownership more affordable for buyers and refinancing more accessible for existing homeowners.

Will $200 Billion Move the Needle?

The challenge lies in scale: the mortgage-backed securities market is valued at roughly $11 trillion, according to LPL Financial. While a $200 billion purchase is substantial, it is unlikely to create a dramatic shift in the mortgage market on its own.

Fannie Mae and Freddie Mac have already been expanding in this direction, boosting their MBS holdings by more than 25% since June and reaching nearly $234 billion by October.

These purchases, combined with Trump’s directive, aim to ease mortgage rates that have remained above 6% for years. Although rates have dipped slightly in recent months, they are still more than double what borrowers saw earlier in the decade.

“Fannie and Freddie have already loaded up their balance sheets with MBS,” wrote Mike Simonsen, chief economist at Compass, on X. “Trump wants more of this. Seems like it'll help rates, gotta wonder how sustainable it is.”

Skeptics remain. Joel Berner, senior economist at Realtor.com, described the impact as “modest and short-lived,” pointing out that the Federal Reserve’s own $2 trillion in MBS purchases dwarfs Trump’s directive. He warned that even if rates fall, more buyers could push home prices higher, erasing affordability gains.

Another complication is the administration’s floated proposal to end government control of Fannie Mae and Freddie Mac. While both trade publicly, the U.S. Treasury has held majority stakes since the 2008 financial crisis. Analysts caution that privatization could raise mortgage rates, undermining Trump’s affordability goals, since government backing currently keeps borrowing costs lower.

This directive marks Trump’s second major housing move in a week. On Wednesday, he announced plans to ban large investors from buying single-family homes, another attempt to ease affordability pressures in a market constrained by tight inventory and high prices.

Trump’s $200 billion mortgage bond purchase directive, alongside his push to ban large investors from buying single-family homes, signals a broader housing reform agenda aimed at lowering rates and improving affordability. While these moves may provide short-term relief, experts caution that the scale of the mortgage-backed securities market and investor dynamics could limit long-term impact. The initiatives highlight Trump’s focus on reshaping housing access, but sustainability and affordability gains remain uncertain.
