The Organisation for Economic Co-operation and Development has published its 2026 assessment of private finance mobilised by official development finance interventions. Mobilisation exceeded USD 600 billion between 2012 and 2024 and reached an annual peak of USD 77 billion in 2024, but remained insufficient relative to development financing needs. Guarantees, direct investment in companies and syndicated loans generated most of the capital mobilised. From 2021 to 2024, middle-income countries received 69% of mobilised finance, while only 8% targeted least developed countries. Economic infrastructure and business-related activities attracted 70%, compared with 6% for social sectors. About 40%, or USD 26.2 billion annually, supported climate action, with nearly 70% of that amount directed exclusively to mitigation and 8% to adaptation. Multilateral development banks accounted for 71% of total mobilisation. The OECD recommends more comprehensive, consistent and granular reporting, greater standardisation of blended finance instruments and stronger co-ordination through country platforms and other multi-stakeholder mechanisms. It is also exploring complementary measures for catalytic interventions, portfolio mobilisation and balance-sheet optimisation, while keeping these distinct from its core transaction-level mobilisation statistics.
