听你说“private investor出30%, Fed借70%”, 好像还有second level buffer. 那样的话就不合算了, 否则没有那么糟。10 x 2% = 20% might worth the risk. I believe the 15x is the max, 10X lever likely be used to reduce turnover.
可是private investor take the 1st 6.6% loss. I think that the bond portfolio has a 6.6% default rate's chance is still there. 到时多大的yield都补不回来principle的损失。 leverage是15倍的。不然不足已有attractive的回报。
