Why are mortgage rates going up?

I earlier stated that posted rates are irrelevant, but the change in them is somewhat more relevant. The change in mortgage rates, however, are dictated by the Canadian government bond market.

5-Year Canada Government Bond Benchmark Yield

As you can see, the 5-year government bond yield is at a high for the year – at 3.06%, it has not been this high since October 2008.

Today some of the major banks increased their posted rates to 6.1% from 5.85%. The best market rate you can receive today on a 5-year fixed mortgage, without going through too much hassle, is around 4.25%. This will likely go up to 4.5% soon.

Over the past 5 years, the peak for the 5-year benchmark government bond yield was 4.72% in the week of June 13, 2007. The posted bank rate then was around 7.3%, and a typical market rate on 5-year fixed rates would have been around 5.8%.

As government bond yields continue to increase, mortgage rates will also follow.
