This document discusses data flow regimes and their implications. It provides an overview of regulatory approaches to data flows in South Africa, other BRICS nations, and international trade agreements. It also analyzes the costs of restrictions to data flows, which can include negative economic impacts like lost jobs and GDP as well as increased costs for data processing and reduced access to innovation. The document concludes by outlining policy options for South Africa, such as maintaining the status quo, liberalizing data flows, or imposing further restrictions, and weighing the pros and cons of each approach.
