Capital and Funds under Administration

The Bank finances its operations by issuing bonds in international capital markets. Since 1962, the Bank has maintained the highest possible credit rating, triple-A. Its financial strength is built upon a solid capital base, conservative investment and lending policies, impressive financial performance, and support from its member countries.

Forty-eight countries from the Americas, Europe, and Asia contribute to the IDB Ordinary Capital (OC) and other administered funds, which the IDB manages on behalf of sovereign and non-sovereign donors. These contributions enhance the financing options available to borrowing member countries.

The IDB's subscribed capital now stands at an impressive US$ 170.9 billion, comprising both paid-in and callable capital, a result of the Ninth General Capital Increase (GCI-9). The GCI-9 marked a historic milestone in the IDB's history, injecting an additional $70 billion in capital subscriptions. Furthermore, following the approval of Resolution AG-9/16 designed to bolster concessional assistance by optimizing the Balance Sheet of the IDB, effective in 2017, the Board of Governors made the strategic decision to transfer all assets and liabilities of the Fund for Special Operations (FSO), including receivables from and payables to member countries, to the Ordinary Capital resources of the Bank as additional paid-in capital.
