美国政府接管“两房”之后，抵押担保债券价格上涨。

Mortgage-backed bond prices rose after the US government seized control of the agencies .

房利美和房地美发行的抵押担保债券收益率更是大幅下挫，这引发了人们对于两家公司支持的房屋贷款利率下降的预期。

现如今，光是在美国公开上市的股票就有数千只，全世界有好几万只，另加数千种公司债券和资产抵押担保债券。

近年来，该领域一直是抵押贷款担保债券市场中增长最快的领域之一。

此次反弹仍然使抵押贷款担保债券的风险溢价（即与国债等资产之无风险利率之间的利差）比信贷危机之前水平高出若干倍，也远远超出推动按揭放贷所需的新交易的水平。

This rally still leaves risk premiums , or spreads over risk-free rates on assets such as government debt , on mortgage - backed bonds many times higher than pre-credit crunch levels and far above rates that would encourage the new deals that are needed to help mortgage lending .

央行干预已帮助推动优质抵押贷款担保的债券强劲反弹，尽管目前市场环境尚未强劲到足以推动新的抵押贷款放贷。

Central bank interventions have helped drive a sharp rally in bonds backed by good-quality mortgages although conditions are not yet strong enough to boost new mortgage lending .
