Uh oh. After easing much of last week, average mortgage rates across the U.S. jumped today, led by a 0.09% hike in 30-year fixed refinance loans. For existing homeowners pondering an equity loan, there's more of the same on that front.

Following the Federal Reserve's recent increase in its benchmark rate, along with the subsequent rise in many banks' prime rates (the rates banks charge their most creditworthy customers and often use to determine the rates on adjustable-rate mortgage), may finally be be causing a slow but sustained rise in mortgage rates, as many pundits predicted.

It's too early to tell whether today's hike is a precursor of things to come or simply a hiccup, but it will be interesting to see what happens with rates in the days and weeks ahead.

Here are today's average mortgage rates across the U.S., along with where they stood a month ago:
