Reports suggest the Trump administration is exploring Federal Reserve purchases of mortgage-backed securities (MBS), a policy that could significantly impact home mortgage interest rates and housing affordability nationwide.

How MBS Purchases Affect Mortgage Rates
When the Fed buys mortgage-backed securities, it increases demand for these assets, driving up their prices and pushing down yields. Since mortgage rates closely track MBS yields, this typically results in lower interest rates for homebuyers and refinancing borrowers.

During the pandemic, the Federal Reserve purchased trillions in MBS, helping suppress 30-year fixed mortgage rates to historic lows around 3%. A renewed MBS purchase program could similarly reduce borrowing costs, stimulating the residential real estate market and improving home affordability.

Presidential Authority and Reality Check: The President cannot directly order the Federal Reserve to purchase mortgage-backed securities. The Fed operates independently, with the Federal Open Market Committee (FOMC) controlling monetary policy decisions. While presidents can influence through appointments and public pressure, the Fed's independence is legally protected.

Likelihood Assessment: Current Fed policy focuses on reducing its MBS holdings, not expanding them. Unless economic conditions deteriorate significantly, renewed large-scale MBS purchases remain unlikely in the near term. The Fed prioritizes inflation control over housing market stimulus.

For homebuyers monitoring mortgage rate trends, conventional monetary policy adjustments—like federal funds rate cuts—remain more probable drivers of lower refinancing rates and improved lending conditions than direct MBS intervention.
