This article analyzes nonprofessional trading in derivatives during the Great Spanish Recession. It depicts playful engagements with speculative forms of credit and debt on the part of everyday people facing mass unemployment. The article calls into question contemporary theories of debt that characterize it as inherently destructive or inherently productive. My main argument suggests that credit‐debt dyads are constant sites of manipulation, negotiation, and improvisation informed by multiple registers of affect, knowledge, and value. In showing how play and playfulness arise in the field of finance, my research sheds light on extractive business models that exploit socioeconomic uncertainties as well as labor reforms advanced in times of recession. My ethnography traverses a variety of social terrains ranging from social media to brokerage firms, trading courses, stock exchanges, and self‐help workshops in order to complicate further the anthropological work on financialization. Without denying the negative and damaging effects of financialization, I focus on the contradictory ways in which ordinary citizens become financial subjects.

游戏危机：西班牙的衍生品和失业

本文分析了西班牙大萧条期间的非专业性衍生品交易。它描绘了日常面临大规模失业的人们以投机形式的信贷和债务进行的有趣活动。该文章对当代债务理论提出了质疑，这些理论将债务特征描述为固有的破坏性或生产性的。我的主要论点表明，信用债务二元性是操纵，谈判和即兴创作的不变场所，并通过多种影响，知识和价值的记录来告知。在显示金融领域的娱乐性和嬉戏性时，我的研究揭示了利用社会经济不确定性以及经济衰退时期进行的劳动改革的采掘性商业模式。我的人种志遍历各种社会领域，从社交媒体到经纪公司，交易课程，证券交易所和自助研讨会，以使金融学的人类学工作进一步复杂化。在不否认金融化的负面影响和破坏性影响的情况下，我将重点介绍普通公民成为金融主体的矛盾方式。
