This paper examines current and suggested iterations of the climate finance architecture and potential risks in capital generation and delivery. Which is achieved via the construction of a literature review which aims to capture the main actors involved in the climate finance architecture. This is then contrasted to a post-keynesian and development economics synthesized framework focusing on liquidity preference, asymmetrical relationships and Minskyan financial instability. Utilizing data on current accounts, private capital flow instability and reserve asset accumulation we are able to show the explanatory power of our synthesized framework in explaining global capital imbalances and its impact on global financial flows and the impact on middle and low income countries. Using the insights gathered from our synthesized framework we then contrast it to the literature review, examining it for observable limitations in capital generation and delivery. In doing so a couple of things are noted, there are significant points of contention relating to capital generation and delivery in the climate finance architecture, potentially resulting in volatile asset prices and a negative impact on effective climate finance. Simultaneously it’s observed that climate finance is not catalytical for financial instability but a growing dependency and intertwining with conventional private financial flows may result in bouts of greater financial instability of climate finance assets. Lastly the paper affirms that there is a need to further examine the role and function of blended finance mechanisms.
