Agile Sustainable Finance: Rethinking Sustainable Finance in Fragile Economies with Insights from Lebanon

Abstract

Sustainable finance models are most often built for contexts characterized by institutional stability, effective governance, and functioning capital markets. In fragile states, such conditions are often absent. This paper revisits sustainable finance through the case of Lebanon, where the post-2019 financial collapse rendered conventional instruments, such as ESG frameworks, green bonds, and sustainability-linked loans, difficult to implement and contextually irrelevant. Drawing on literature regarding sustainable finance, degrowth and post-growth economics, and the political economy of fragility, the paper proposes a conceptual framework for Agile Sustainable Finance: a model that explains how financial practices oriented towards sustainability can persist despite institutional collapse with agility operating as the mediating capability. The model positions agility as the central capability enabling households, firms, and communities to reorganize financial life amid institutional erosion, liquidity shortages, and involuntary degrowth. It highlights how informal credit systems, remittances, community financing, and decentralized energy solutions become essential tools for resilience and ecological sufficiency in collapsed economies. By reframing finance as a mechanism for survival, redistribution, and basic sustainability rather than growth, this conceptual study offers a theoretical model that bridges domains that rarely intersect: sustainable finance and fragile-state dynamics.
