Abstract: The uniqueness of financial English lies in its great number of technical terminology. The American financial crisis, stemming from the subprime mortgage crisis, also involves many financial terms, some of which were not common in the past. Eco-translatology is a new theory of translation with great interpretation capacity. Guided by eco-translatology, this paper selects a number of important terms frequently used in studies of the current American financial crisis, and compares different versions of their translation. Through analyzing their adaptability in the linguistic, cultural and communicative dimensions, best translation versions are recommended.
