Rates on 30-year new purchase mortgages dropped for a sixth day Thursday, ticking down 1 basis point to an average of 6.59%. In the past six days, the flagship rate has shed 24 points. The current average of 6.59% establishes a new low point for this year.

That was popularly known as quantitative easing. Buying MBS can reduce mortgage rates by increasing competition and increasing mortgage market liquidity.
