摘要:在2011年5月，美国国债触顶，开创了14.29万亿美元的历史新高。面对这种情况，美国财长盖特纳忧心忡忡。他表示，由于采取了一些紧急措施以维持借债能力，美国政府支付开支最多能延迟到8月2日。到了8月2日，政府若不提高债务上限或削减开支，就会开始债务违约，无法偿还美国国债券本金和利息，这种情况可能让国际金融市场陷入混乱。并且在这个时候标普下调了美国主权债务的信用评级到AA+，展望为负面。而美国陷入债务危机后将对全球经济产生巨大的影响，可能会带领全球经济下滑并且对中国贸易市场产生巨大影响。而中国现如今的外汇储备主要是美元，如果美元进一步贬值，会使中国的财政蒙受很大的损失，而且美元贬值也就是人民币的升值，使得国内一些以出口为主了企业蒙受巨大的损失，甚至会使很多企业破产，从而会导致中国通货膨胀加剧，使得很多商品的物价持续上涨，从而影响到中国的市场经济与对外贸易。本文论述了美国主权债务危机的原因以及对我国对外贸易产生的影响，并提出对策建议。
