This working paper begins the process of framing a just transition narrative in the context of the South African financial system. It provides a brief overview of the current financial system in South Africa focusing on the structural fit of the finance system to the real economy, specifically in relation to small start-up companies, new entrepreneurial activities and new (often untested) technology roll-outs which characterise climate action and social inclusion transition activity. It looks at current local thinking about the system-level demands of a sustainable transition of the financial sector at a high and conceptual level. It then presents a framework and approach to understanding the financing needs of a just transition in South Africa.
