Mortgage rates usually follow the bond market more than any single announcement. When investors expect stronger growth or higher inflation, long term bond yields rise, and mortgage rates tend to follow. Federal Reserve policy, inflation reports, and demand for mortgage backed securities all feed into that pricing. Lender competition and borrower credit profiles then decide the rate any one borrower is offered.
Small rate moves change payments more than most buyers expect. The example above shows a 0.69 point swing adding about $149 a month on a $320,000 loan. Rerunning the mortgage calculator with the current rate is the fastest way to see what a move means for your own payment.
