International Day of Banks – Mobilizing Finance for Sustainable Development and Civil Society Impact

Each year on December 4, the United Nations observes the International Day of Banks, as per General Assembly Resolution A/RES/74/245, adopted on 19 December 2019. This observance is far from ceremonial. For nonprofit and NGO leaders engaged in global development, it offers a unique insight into how banks—especially development banks—play a pivotal role in sustainable finance and systemic resilience.
The resolution explicitly recognizes the “significant potential of multilateral development banks and other international development banks in financing sustainable development and providing know‑how.” Likewise, it underscores how national banking systems contribute to improving living standards in member states.
Why Banks Are a Strategic Lever for International Development
The creation of this day is rooted in a broader acknowledgment that banks are more than financial intermediaries: they are crucial development actors. Firstly, multilateral development banks (MDBs) channel large volumes of long-term capital into projects that markets alone may under-finance. These include infrastructure, climate resilience, and social services—investments that typically require patient capital and technical expertise. Secondly, domestic banking systems, when inclusive and well-regulated, expand access to finance, which is essential for economic growth and poverty reduction.
In this light, the International Day of Banks is not merely a symbolic recognition, but a call to align the global financial architecture more closely with the Sustainable Development Goals.
Complex Numbers: What the Latest Data Reveal
To understand the real impact of development banks, it is essential to examine the numbers. In 2024, MDBs collectively delivered a record USD 137 billion in climate finance—a 10 percent increase over the previous year.
Of that amount, roughly USD 85.1 billion was allocated to low- and middle-income economies—an increase of 14 percent year-over-year. Within these countries, 69 percent (about USD 58.8 billion) was assigned to climate-mitigation projects, with the remaining 31 percent (USD 26.3 billion) focused on adaptation.
Another striking figure: MDBs mobilized USD 134 billion in private climate finance in 2024, representing a 33% increase compared to 2023.
Meanwhile, in 2022, MDB climate finance to low- and middle-income economies reached USD 60.9 billion, a sharp increase from previous years. Of that, USD 38.0 billion was for mitigation and USD 22.7 billion for adaptation. That same year, global MDB climate finance neared USD 100 billion, while private finance mobilized reached around USD 54 billion.
These numbers illustrate how development banks are increasingly bridging the gap between public resources and private capital—especially for climate-related investments.
Structural Challenges and Persistent Gaps
Despite these gains, development banks continue to face significant structural constraints. According to an OECD analysis, more than three-quarters of MDB climate finance between 2020 and 2022 was delivered via debt instruments, primarily loans. While loans are indispensable, their dominance raises questions about debt sustainability for borrowing countries and the balance of finance toward grants or more concessional forms.
The OECD also reports that MDB business models may not be fully aligned with their long-term climate ambitions. A recent Multi-Partner Evaluation Network assessment highlighted weaknesses in staffing, risk management, and innovation capacity—gaps that could hinder MDBs from fulfilling their commitments under the COP28 framework.
Another technical but significant risk is “name concentration risk.” A recent working paper examines how MDB sovereign loan portfolios typically have high exposure to a small number of borrowing countries. This concentration poses significant risks, yet current capital adequacy frameworks may be overly conservative or misaligned.
Finally, research on development finance institutions (DFIs) in Sub-Saharan Africa found that while DFIs theoretically boost foreign direct investment, their actual impact is highly context-dependent, shaped by political stability, governance, and institutional capacity.
Implications for Nonprofit and NGO Stakeholders
For NGO and nonprofit leaders, especially those operating in international development, the International Day of Banks offers a strategic moment to reflect but also to act.
- Advocacy leverage: Use the observance to press MDBs on transparency, climate accountability, and risk management. Encouraging better reporting, stronger safeguards, and alignment with SDGs can tilt bank investments toward higher-impact sectors.
- Partnership opportunities: NGO actors can propose co-financing models or technical assistance arrangements with development banks. For example, nonprofits with deep expertise in adaptation or social infrastructure may serve as knowledge partners in bank-funded programs.
- Capacity and systems building: Nonprofits can help strengthen domestic banking systems by working with banks on financial inclusion, gender finance, or capacity building—making national banks better partners for development.
- Mobilizing private capital: Given MDBs’ success in leveraging private finance, NGOs can play a role in structuring blended finance, mobilizing grant capital, or supporting financial innovation focused on underserved communities.
A Call for Reflection and Reform
The International Day of Banks is more than a date on the calendar. For the nonprofit sector, it is an invitation to examine how banks contribute to or fall short of the promise of sustainable development.
If banks are to fulfill their recognized potential, three priorities must guide our collective work: (1) greater policy coherence, so that realistic country strategies match MDB commitments; (2) financial innovation, to shift more capital into adaptation, inclusive finance, and underfunded development areas; and (3) accountability mechanisms, where civil society holds institutions to measurable, impact-oriented goals.
On December 4, leaders in NGOs, civil society, and global development should not only mark the day but also seize it as an opportunity to shape how banks deploy capital, carry out technical knowledge, and partner for a sustainable and equitable impact.
