Financialization is one of the most relevant processes embedded in the functioning and evolution of the contemporary capitalist model and presents differential characteristics in the peripheral economies of the world-system. In turn, land grabbing is also one of the most relevant phenomena taking place in the field of farmland and land use, with particular significance also within the Global South. After presenting an in-depth analysis of both phenomena for Latin America, we specifically study the case of the two Latin American countries (Argentina and Brazil) where land grabbing has a greater qualitative and quantitative importance. In our article, we analyze the main interrelationships between both processes and show how financialization has played a fundamental role (together with the policies designed and the de-regulations implemented by respective states, and the participation of other domestic actors) in the land grabbing process in both countries.
