ABSTRACT Sustainable supply chain finance (SSCF) faces challenges due to supply chain disruptions, often resulting in delays and cost overruns. The existing literature lacks a theoretical framework to delineate the interrelationship between internal and external SSCF enablers. This gap leaves firms exposed to financial risks and impedes their long-term sustainability. This study addresses a gap in the literature by integrating internal competencies and external pressures as enablers in SSCF during disruptions. Employing institutional and dynamic capability theories, it identifies and analyses 45 enablers through the fuzzy Delphi method and the fuzzy decision-making trial and evaluation laboratory. The findings emphasise the driving roles of collaboration value innovation, financial stability, and operational capacity in enabling SSCF. These aspects foster a response to disruptions, particularly in enhancing environmental, social, and governance efforts. In practice, demand forecasting, decision synchronisation, stakeholder relationships, working capital, and financial information sharing offer perspectives on enabling SSCF under disruptive conditions.
