ABSTRACT
BACKGROUND:
Recent global crises, including COVID-19, climate shocks, debt distress, and widening inequalities, have exposed the limitations of fragmented global governance. At the same time, four consecutive G20 presidencies from the Global South (Indonesia 2022, India 2023, Brazil 2024, South Africa 2025) have foregrounded development, equity, and social inclusion within G20 processes. This paper examines the extent to which these presidencies collectively advanced a Social Determinants of Health (SDH)–oriented vision of multilateralism, even in the absence of explicit SDH framing.
METHODS:
The study undertakes a qualitative desk review of G20 Leaders’ Declarations, ministerial communiqués, and outputs of the Joint Finance–Health Task Force across the four presidencies. The analysis maps G20 commitments across health, finance, and development domains against core SDH dimensions, including social protection, food and nutrition security, primary health care, gender equality, digital inclusion, employment, and climate resilience.
RESULTS:
Findings indicate a sustained shift in G20 priorities towards structural drivers of health and wellbeing. Commitments increasingly recognise inequalities in income, employment, housing, education, and access to essential services as macro-critical risks affecting growth, fiscal stability, and resilience. While SDH is not formally institutionalised within G20 governance, there is growing policy coherence across health, economic, and social agendas, reflecting an implicit SDH logic shaping development-centred multilateralism.
CONCLUSIONS:
Institutionalising SDH within G20 governance could enhance continuity, legitimacy, and effectiveness in addressing intersecting global challenges. The paper proposes the development of a G20 SDH Metric to support vulnerability-indexed financing, SDH-linked concessional instruments, and stronger alignment with global processes such as the World Summit for Social Development, Financing for Development, and climate COPs. Embedding SDH positions the G20 as a strategic platform for equitable and resilient global development.
