The same reckless lending practices – no down-payments, no verification of borrowers’ incomes and assets, interest-rate-only mortgages, negative amortization, teaser rates – occurred in more than 50% of all US mortgages in 2005-2007. Because securitization meant that banks were not carrying the risk and earned fees for transactions, they no longer cared about the quality of their lending.
问题不仅仅在于次级抵押贷款。同样鲁莽的借贷行为，也就是没有首付金、没有核准借款者的收入和资产、定息抵押贷款、负摊销、引逗利率等等在2005至2007年 全 美国的抵押贷款中占据了超过50%的比例。因为证券化意味着银行不再承担风险，并且能够从交易中赚取费率，它们于是不再关心它们借贷的质量。
