What’s bad economic news for Wall Street sometimes means great news for others.

Specifically, home buyers, who stand to get a great bargain on mortgage rates as a result of a topsy-turvy bond market during the week’s wave of fear gripping world markets and routing stocks.

To escape stock wipeouts, most investors have been fleeing en masse to the safety of US Treasury securities and the stability they offer despite their weak yields. The exodus sent Treasury prices soaring, while their yields, which have an inverse relationship with prices, sank toward new yearly lows.

The yield of the benchmark 10-year US Treasury note, on which home mortgages are based, dived to 3.22 percent — at one point touching 3.19 percent intraday. At the end of the session, the drop was the biggest single-day decline in the 10-year’s yield in 14 months.

Analysts said the low yield signaled a summer ahead of cheap home loans below the 5 percent mark, and a possible jump in housing deals. A single percentage point in a mortgage equals tens of thousands of dollars over time.

“There is money flowing out of Europe and into US Treasuries, and that has been going on for days,” said fixed income trader Raymond Remy at Daiwa Securities.

The shifts into fixed investments also raised hopes that inflation would remain flat, investors said.

Some economists fear that huge auctions each month of US Treasury securities to raise new cash will cause a glut in a global market already saturated with US notes.
