Chart 3

Charts 4 through 8 show speeds for fixed-rate mortgages by vintage. Here too, both y-axes for all three charts have the same scale so that it is easy to track speed levels as well as percent differences in speeds by vintage.

We see an interesting trend for the fixed rate mortgages. The percent difference in speeds start going up around July 2006. Except for the 2007 vintage, the percent difference in speeds goes from slightly over 10% in July 2006 to over 20% in October 2007. The increase is more gradual and happens over a longer time-period compared to ARMs.
