Multilateral development banks (MDBs) face pressure to finance development, climate transition and debt-resilient growth, yet how institutional design shapes their operational models remains understudied. This study compares the Asian Development Bank (ADB), the Inter-American Development Bank (IDB), and the African Development Bank (AfDB), the regional development banks of their continents, which share an institutional form and AAA ratings but differ in governance configuration. The banks are compared along three dimensions: governance legitimacy, financial instruments, and sectoral alignment. Using a comparative institutional approach, the study analyzes the banks' annual reports, financial statements, and strategy documents for 2022–2024. Although all three banks hold AAA ratings, each balances legitimacy against financial capacity differently: the ADB relies on non-regional shareholder backing and a technocratic orientation, the IDB on a negotiated borrower–donor balance, and the AfDB on regional ownership and concessional finance. The ADB shows the diversified instrument mix and the highest efficiency (71% disbursement ratio, 10-month approval time); the IDB relies on policy-based lending, and the AfDB on blended finance. Climate finance unites all three, reaching 41–49% of 2024 approvals and about USD 25 billion. Effectiveness depends less on scale than on the fit between governance, instruments and regional priorities
