Capping a roller-coaster year, the "Trump reflation" saw mortgage rates end 2016 near five-year highs

It's been a roller-coaster year for interest rates, and consequently, for mortgage rates, too. In July, in the wake of the United Kingdom's surprise rejection of membership in the European Union ("Brexit"), mortgage rates fell to within spitting distance of their all-time lows.

However, at the beginning of November, an even greater political earthquake, Donald Trump's electoral victory, set mortgage rates on a reverse course in double time. As the following graph shows, the 30-year and 15-year fixed-rate mortgage rates shot up, passing their highs for the year, and ending 2016 near their five-year highs. (The broken horizontal lines represent the most recent levels.)

The "Trump reflation" has had a stunning effect on mortgage rates, abetted by the Federal Reserve's December rate hike, with expectations of three more to come next year. While there are reasons to believe rates could continue to rise next year, it's by no means a certainty.

Potential homebuyers may have "non-buyer's remorse" when they look back at the rates they could have obtained in July, but timing the bottom is impossible, whether in stocks or rates. Even after their recent run-up, mortgage rates remain very affordable by historical standards.
