This paper aims to identify the inflection point in financial discourse, the moment of explosion and unpredictability in the 2007–2008 economic crisis, through an analysis of metaphors, and its relation to the concept of jumps in finance. The corpus is formed by articles dating from 2007–2008 published in The Wall Street Journal and related to the movements of the Standard & Poor’s 500 index (S&P500) of the United States. For the purposes of this paper, two texts are analysed: “Traders in Lehman, AIG held out hope – Friday”, and the speech “Four questions about the financial crisis” by Ben S. Bernanke. What is of particular interest is the transformation of unpredictability to predictability, as incorporated in this type of discourse to indicate a predetermined chain of events, chosen from a wide spectrum of possibilities. The theoretical framework draws on Juri Lotman’s views on the concepts of explosion, unpredictability, inflection point and predictability.

2007–2008年危机的金融讨论：从不可预测性和爆炸性到可预测性

本文旨在通过对隐喻的分析及其与金融跳跃概念的关系，来确定金融话语的拐点，2007-2008年经济危机中的爆炸时刻和不可预测的时刻。该语料库由《华尔街日报》（The Wall Street Journal）上2007年至2008年之间发表的文章构成，与美国标准普尔500指数（S＆P500）的走势有关。为了本文的目的，分析了两个文本：“ AIG雷曼交易员表示希望-星期五”，以及本·伯南克（Ben S. Bernanke）的演讲“关于金融危机的四个问题”。特别令人感兴趣的是将不可预测性转换为可预测性，将其纳入这种类型的话语中，以指示从多种可能性中选择的预定事件链。
