This paper presents the journalistic corpus as a valuable resource in acquiring critical knowledge. Translator training in economics and finance must incorporate this skill set, especially at a time when an increasing volume of texts from these fields is expected to be processed through neural machine translation. The paper aims to support teaching practices that acknowledge the work of translators as actively engaged in constructing social reality. This posture is delineated within critical discourse analysis, which is helpful in understanding the broader context of the financialized economy. After a brief review of approaches to teaching economic and financial translation, the article proposes three entry points into the critical analysis of a journalistic corpus: lexicon and vocabulary, agency and voice. Some praxeological aspects are discussed, such as how to build a corpus from newspapers.
