What causes mortgage interest rates to rise in the US?


assistant
Mortgage rates are tied to many factors including the inflation, economic growth, and the Federal Reserve's (Fed) monetary policy. For instance, if the Fed increases rates, this usually results in increased mortgate rates since banks need to ensure that the loan can achieve better returns than investing in US bonds.
