What Is Blended Finance?

Blended finance is the strategic combination of public, private, and philanthropic capital to mobilize additional investment for sustainable development projects.

By blending different types of capital, blended finance aims to address market failures and create opportunities for private investors to support social and environmental goals.

The role of blended finance in development and investment is to bridge the funding gap between the public and private sectors.

This is achieved by leveraging public and philanthropic funds to attract private capital for investments in projects that advance the United Nations Sustainable Development Goals (SDGs).

Blended finance helps overcome market barriers and catalyzes private investments in sectors that might otherwise be considered too risky or unprofitable.

The primary objectives of blended finance are to mobilize private sector investment, reduce risks for private investors, and enhance the financial viability of development projects.

By combining different sources of capital and risk-sharing mechanisms, blended finance aims to increase the scale and impact of development efforts while promoting market-based solutions to global challenges.

Key Components of Blended Finance

Concessional Finance

Concessional finance is provided on terms more favorable than market rates, often by public or philanthropic organizations, to encourage investment in development projects.


Grants are non-repayable funds provided by governments, multilateral institutions, or philanthropic organizations.

They can be used to cover project costs, provide technical assistance, or support capacity-building efforts, reducing the financial burden on project developers and beneficiaries.

Low-interest loans

Low-interest loans offer financing at below-market rates, making them more affordable for borrowers.

By providing access to capital at favorable terms, low-interest loans can encourage investment in projects that may be considered too risky or not financially viable under market conditions.


Guarantees are financial instruments that protect investors from potential losses, usually by covering a portion of the debt in case of default.

By mitigating risks for private investors, guarantees can help mobilize additional capital for development projects and encourage greater private sector participation.

Commercial Finance

Commercial finance is provided by private sector actors, such as banks, institutional investors, and impact investors, at market rates and conditions.

Market-rate loans

Market-rate loans are a common form of commercial finance offered by banks and other financial institutions.

These loans provide capital for projects at interest rates that reflect market conditions, allowing investors to earn a return on their investments while supporting development initiatives.

Equity investments

Equity investments involve purchasing ownership shares in a company or project, providing capital in exchange for a stake in the potential profits.

This form of commercial finance aligns the interests of investors and project developers, as both parties benefit from the success of the investment.


Bonds are debt instruments issued by governments, corporations, or financial institutions to raise capital for projects.

Investors purchase bonds in exchange for regular interest payments and the return of the principal amount at the end of the bond's term. Bonds can be an attractive investment for those seeking stable returns while supporting development initiatives.
