Commercial mortgage bond index spreads soar again

NEW YORK, Nov 20 (Reuters) - Yield spread premiums on a commercial mortgage-backed securities index soared more than 100 basis points for a third straight day on concern that economic growth would push defaults on office buildings and retail centers sharply higher.

Spreads on the CMBX-5 AAA derivative index of recent CMBS jumped 135 basis points in early trading to a record high of 850 basis points, according to a dealer quote.

Selling from investors reducing assets financed on borrowed money exacerbated the spread widening, analysts said.
