My guess is interest rates have been going up which means higher auto and mortgage loans. Mortgage originations have dropped off quite a bit since the spring. That is not good for big institutional investors that need to flip out of their current positions.
A 30 year fixed rate mortgage currently goes for 4.71 per cent, an increase of about .32 per cent since the beginning of July. Most analysts seem to think that demand pool for residential refinancing has been satisfied, with new mortgage origination slow due to broad economic weakness and a diminished inventory of new residential housing.
