Weekly Jumbo Mortgage Interest Rates Update

Jumbo mortgage rates, the interest rate paid on mortgages above the government sponsored entity (GSE) conforming loan levels, remained relatively flat this week continuing a pattern of little movement over the last number of weeks. Jumbo mortgage rates tend to be higher than normal mortgage rates due to the fact that lenders cannot easily sell the loan to Fannie Mae or Freddy Mac, the two largest GSEs which purchase mortgages.

The 30 year fixed Jumbo was being offered around 4.48% on November 30. This is nearly unchanged from the November 23 rate which settled at 4.49%. For the month of November the 30 year fixed Jumbo declined slightly from 4.65% at the end of October. While mortgage rates may vary depending on the local market the national average rates have been unusually stable.

In similar fashion 15 year fixed Jumbo mortgage interest rates have also remained flat. On November 30 the national average rate came in at 3.72%. This was only slightly higher than a week ago when the rate was quoted at 3.70%. Over the last month the 15 year rate has been even more stable than its 30 year counterpart. At the end of October the national average was at 3.68%, a mere five basis points lower than the current rate.

Jumbo loan rates are also quoted for the 5/1 adjustable rate mortgage (ARM) where the initial interest rate is fixed for the first 5 years of the mortgage but then adjust every year thereafter based upon the prevailing current market rate. The 5/1 ARM Jumbo loan rates mirrored their fixed cousins, remaining little changed over the last week. The national average on November 30 was 2.90%, only slightly higher than the previous week’s 2.88% average rate. One month ago the 5/1 ARM Jumbo was quoted at 3.08%.

It is unclear whether the future will continue to yield relatively stable Jumbo rates or whether more volatility is in store. Many macroeconomic forces act upon interest rates and any change in the economic environment can cause rates to move. The relative recent quietness of the US Federal Reserve has helped keep rates stable and fears regarding Europe’s debt have kept investors locked into US debt assets. Any sign of significant problems in the US economy will increase instability of Jumbo mortgage interest rates.
