The climate crisis is far from being just an environmental issue; it is a transformative force reshaping countries’ economic and financial structures. Its impact across multiple sectors exposes the vulnerability of current development models and call for a systemic response.

In Latin America, where much of the region’s critical infrastructure and productive base depends on climate-sensitive natural resources, these impacts translate into fiscal losses, logistical disruptions, and growing pressure on public budgets.

In this context, climate finance becomes both a source of tension and an opportunity. According to the Inter-American Development Bank, the region needs to invest between 7% and 19% of GDP to achieve sustainable and resilient growth. The challenge, however, is not only about mobilizing capital, but about organizing it—requiring institutional capacity to connect public priorities with financial instruments and turn policy into real investment.

It is within this structural coordination gap—often a bottleneck for anticipating climate risks and capturing opportunities for productive transformation—that National Development Banks play a critical role. With the mandate, capabilities, and legitimacy to act as a bridge between public policy, markets, and territories, NDBs are uniquely positioned to lead.

Bridge Institutions and Market Architects

By definition, NDBs are bridge institutions. They translate public priorities into concrete financial tools and connect national strategies with real investment decisions. Beyond channeling resources, they often act as market architects—building capacity where it doesn’t yet exist, structuring demand, sending clear signals, and helping mature sectors that private markets are not yet ready or willing to tackle on their own.

In the context of the climate crisis, this role is not optional—it’s strategic. Unlike other actors, NDBs can align public policy, financing, and implementation within a single institution, something extremely difficult to achieve through ministries, regulators, or commercial banks acting separately. They are also better positioned to take on and manage key transition risks that often fall outside the scope of traditional finance, including climate, regulatory, technological, and early-stage market risks.

In this sense, climate change is redefining the historical mandate of NDBs. They are no longer just financing development; they are increasingly expected to anticipate systemic risks and enable viable future pathways.

Anticipating Risks, Catalyzing Opportunities

One of the most important contributions NDBs can make is integrating climate risk into financial and credit management. Physical and transition risks remain poorly understood in many markets. NDBs can help organize data and signals, translating them into financial and operational terms—making climate risk less abstract and more manageable.

Through well-designed public instruments, NDBs can also crowd in private capital, lower entry barriers, and build investment pipelines that move beyond isolated projects toward scalable, replicable programs. The climate transition isn’t financed one project at a time—it’s built through portfolio thinking, institutional learning, and adaptive capacity, all areas where NDBs have a clear comparative advantage.

Evidence from the Region

Across Latin America, National Development Banks are already putting climate at the center of their operations. At ImplementaSur, we’ve seen this firsthand through recent work in Colombia and Central America, including concrete progress on methodologies to identify and manage climate risks, measure financed emissions, and integrate TCFD criteria into institutional policies.

The pattern is clear: NDBs are expanding their mandate—from financing development to anticipating risk and enabling structural transformation.

At a critical moment for the region, the scale of the climate challenge begs for new alliances between development banks, the private sector, and public policy. Spaces like CAF’s 2026 Latin America and Caribbean International Economic Forum will be key to elevating this discussion to the strategic level it demands—one that goes beyond tools and instruments to rethink the institutional role NDBs are meant to play in this decisive decade. Recognizing, strengthening, and supporting that role is not just a technical choice but a fundamental development decision.
