建议楼主看一些这方面的英文文章,相关单词就基本出来啦^_^The subprime mortgage crisis is a current economic problem characterized by contracted liquidity in the global credit markets and banking system. An undervaluation of real risk in the subprime market ultimately resulted in cascades and ripple effects affecting the world economy generally.The crisis began with the bursting of the US housing bubble and high default rates on "subprime" and adjustable rate mortgages (ARM). Loan incentives, such as easy initial terms, in conjunction with an acceleration in rising housing prices encouraged borrowers to assume difficult mortgages on the belief they would be able to quickly refinance at more favorable terms. The mortgage lenders that retained credit risk (the risk of payment default) were the first to be affected, as borrowers became unable or unwilling to make payments. Major banks and other financial institutions around the world have reported losses of approximately U.S. $435 billion as of July 17, 2008.次贷危机:Subprime mortgage crisis 美国房地产泡沫:US housing bubble流动性:liquidity 无法偿还房贷和丧失抵押赎回权:home-loan defaults and foreclosures发放次贷的出贷方:subprime lenders借贷打包证券和银行持有的投资组合:loans packaged into securities and held in bank portfolios可调整的贷款利率:adjustable-rate mortgages(ARM)贷款欺诈:fraudulent loans信用危机:credit risk 证券化:securitization住房抵押贷款证券mortgage-backed securities(MBS)抵押债务:collateralized debt obligations(CDO)机构投资者:institutional investors以上是我总结的一些基本词汇 楼主考研加油哦
