If you paid attention to the Federal Reserve's monetary decisions last year, you might have been surprised by something: The central bank's three interest rate cuts didn't help mortgage rates get cheaper for homebuyers.

U.S. President Donald Trump is getting his wish that interest rates drop across the world, just not at home where a strong economy and uncertainty over his own policies have set the stage for the Federal Reserve to diverge from its central bank peers.

It's important to understand that the Fed's decision to pause rate cuts will not directly impact mortgage rates. Mortgage rates are actually driven by a range of factors, including the Fed's rate changes. This week's Fed rate decision does, however, have a big influence on where mortgage rates could head.
