Imagine this: you’ve found your dream home, but the monthly mortgage payment you planned for suddenly jumps — not because your bank changed its policies, but because of a decision made in Washington.
Globally, borrowers are increasingly curious about why home loan interest rates move up or down. The answer often lies with the US Federal Reserve (Fed), which plays a central role in shaping borrowing costs. While the Fed doesn’t directly set mortgage rates, its policy decisions ripple across global markets.
Understanding how central banks affect mortgage rates gives you an edge in timing your next purchase or locking in the best home loan rates available.
The Federal Reserve’s Role in Setting Borrowing Costs
The US Federal Reserve (Fed) plays a key role in shaping the cost of borrowing worldwide. Its primary tool is the federal funds rate — the interest rate at which banks lend money to each other overnight. By adjusting this rate, the Fed directly influences short-term borrowing costs across the financial system. Its broader goal is to manage monetary policy to control inflation while supporting economic growth and employment.
For consumers, these policy changes often trickle down to mortgage rates. When the Fed raises the federal funds rate, banks face higher borrowing costs, which typically leads to increased mortgage loan interest rates. Conversely, when the Fed cuts rates, banks can lend more cheaply, helping lower home mortgage rates.
Quick Fact: “In the US, the Fed doesn’t set mortgage rates directly — but it pulls the levers that move them.”
How Fed Rate Cuts Impact Mortgage Rates
When the Federal Reserve cuts its policy rates, it sets off a chain reaction that affects borrowers worldwide. Lower federal funds rates mean banks can borrow money more cheaply, and these savings are often passed on to consumers via reduced mortgage loan interest rates.
For homebuyers, this translates into more affordable borrowing and potentially lower monthly repayments. Lower rates also tend to stimulate housing demand, as buyers rush to secure the best home loan rates before the next shift.
For example, in early 2025, a 0.25% Fed rate cut pushed 30-year fixed mortgage rates in the US below 6% for the first time in over a year.
| Month | Fed Funds Rate (%) | Average 30-Year Fixed Mortgage Rate (%) |
| Aug 2024 | 5.25 | 7.1 |
| Nov 2024 | 5.00 | 6.8 |
| Feb 2025 | 4.75 | 6.4 |
| May 2025 | 4.50 | 6.1 |
| Jul 2025 | 4.25 | 5.9 |

This shows how Fed rate cuts can directly bring down mortgage loan rates, improving affordability for borrowers.
The Reverse Effect – When the Fed Raises Rates
Just as rate cuts make borrowing cheaper, Fed rate hikes push costs higher. When the federal funds rate rises, banks face increased borrowing expenses, which are passed on to consumers through higher mortgage loan interest rates.
Aggressive hikes can cool housing markets by making loans less affordable. Between mid-2022 and late 2023, the Fed raised rates multiple times to combat inflation. As a result, home mortgage rates soared, delaying purchase decisions for many potential buyers.
Did You Know? “In 2023, US mortgage rates hit 7.8%, the highest in over two decades, following a string of Fed hikes to tame inflation.”
Why the Fed’s Decisions Affect Mortgages Globally
The US Federal Reserve doesn’t just shape borrowing costs in America — its influence extends worldwide. Since the US dollar acts as the world’s reserve currency, Fed policy often sets the tone for global mortgage loan rates.
In countries like Singapore, mortgage rates are frequently tied to benchmarks like SORA, both of which are heavily influenced by Fed decisions.
Quick Fact: “When the Fed cuts rates, borrowing costs in Singapore often ease too, leading to lower home loan interest rates and more competitive refinancing opportunities.”
Even if you’re outside the US, your mortgage interest rates can still feel the ripple effect. Monitoring the Fed rate cuts 2025 impact can help you time purchases, refinancing, or securing the best mortgage rates in Singapore and globally.
