Looking across Latin American markets, it is clear that Brazil has already mastered the vocabulary of impact finance and innovative financing: blended finance, matchfunding, venture philanthropy. But so far, this has not necessarily translated into the financial infrastructure needed to operate at the scale required to address social and environmental challenges in a country as large and complex as Brazil.
Take blended finance, for example. The model uses catalytic capital—public or philanthropic—to improve the risk-return profile of investments and attract private capital to areas that would otherwise struggle to mobilize funding at scale. According to Convergence, the global network for blended finance, this approach has already mobilized more than USD 270 billion in commitments worldwide. Yet its potential remains underused across the Global South, particularly in Brazil. This is not because capital is unavailable, but because many transactions require levels of coordination, legal certainty, risk appetite, and technical expertise that are still not widely available across the ecosystem.
Our bottleneck is not a lack of money. It is a lack of infrastructure and established practices. The field is caught in a paradox: it knows how to design sophisticated transactions but struggles to replicate them quickly. The real leap will come when we recognize that innovative finance is about more than creating new terminology or financial instruments.
We need to build the infrastructure that allows these financing models to work at scale, rather than treating every transaction as an exceptional case dependent on particular leaders, painstaking negotiations, and bespoke arrangements. We need standards, shared knowledge, and institutional capabilities that allow these models to be deployed more predictably.
The first key area is regulation. Hybrid structures require predictability and clear rules for guarantees, first-loss capital, funds combining philanthropic capital with other sources of finance, and outcomes-based financing mechanisms. In Brazil, for example, the country is beginning the implementation of a major reform of its consumption tax system in 2026. This transition creates an opportunity to calibrate incentives and establish clearer treatment for financing arrangements designed to advance public-interest goals.
The second area is cultural: patient capital. Philanthropy and private social investment—the term commonly used in Brazil for the strategic allocation of private philanthropic resources for public benefit— still often operate on short time horizons and with limited tolerance for risk. Financial innovation, however, requires the opposite: multi-year commitments, flexible funding, a willingness to finance organizational infrastructure—including teams, data, and evaluation—and an understanding that learning has a cost and that failure can be part of the process.
This is critical. Many initiatives designed to generate positive impact do not fail because their underlying solutions are weak, but because they lack financing suited to their stage of development. Promising initiatives may need support to refine their operating models, organize data, strengthen governance, measure results, or adapt their work to different local contexts. When philanthropy funds only the final outcome rather than the infrastructure that makes delivery possible, it constrains organizations’ ability to develop and reinforces a cycle of short-term, project-based funding that undermines long-term sustainability.
The third piece is coordination. Public, private, and philanthropic capital do come together today, but often without sufficient coordination. The result is fragmentation: multiple actors may fund initiatives in the same communities without shared governance, while others try to introduce market-based solutions before risks have been sufficiently reduced to attract commercial capital. This is where intermediaries become part of the financial infrastructure: they translate between sectors, manage projects, standardize due diligence, establish baseline metrics, and assemble blended and multi-capital structures efficiently.
Brazil already offers concrete examples of what can happen when these elements come together. Together for Health, an initiative of BNDES, Brazil’s national development bank, managed by IDIS – Institute for the Development of Social Investment, uses a matching-funds model that combines public funding with non-repayable private contributions to strengthen Brazil’s Unified Health System (Sistema Único de Saúde, or SUS), the country’s universal public healthcare system, in the North and Northeast regions.
Financial infrastructure can also operate at the global level. The Tropical Forests Forever Facility (TFFF), launched at COP30, was designed with the ambition of mobilizing USD 125 billion, with at least 20% of its resources intended for Indigenous Peoples and local communities—a structure that combines scale, governance, and explicit allocation rules.
By recognizing standing tropical forests as assets that generate value for the global community and establishing payments linked to forest conservation, the mechanism highlights an important trend: the climate agenda will increasingly require financial architectures capable of bringing together different types of capital, protecting vulnerable communities and ecosystems, and distributing benefits more equitably.
The climate crisis makes this debate even more urgent. Extreme weather events, economic losses, water insecurity, health impacts, and growing pressure on vulnerable populations demonstrate the limits of fragmented responses. Prevention, adaptation, and resilience require financing before an emergency occurs, not only after disaster strikes. Philanthropy can play a central role by funding planning, local capacity, early-warning systems, nature-based solutions, and locally led governance arrangements that reduce future risks.
The question, then, should not be what the next financial instrument will be, but what infrastructure we need to build so that these instruments can become standard practice rather than exceptions. If we want to address the climate crisis, inequality, and limited state capacity in vulnerable communities, we need to start treating innovative financing as part of the essential infrastructure needed to address twenty-first-century public challenges.
This is an invitation to the field: direct a portion of capital not toward the final project itself, but toward the system that allows projects to exist and succeed. That means financing first-loss capital, guarantees, project preparation, data, and evaluation; supporting intermediary organizations; and, above all, combining different sources of capital through shared governance.
Instead of creating more brilliant pilots, we need to build a system that can replicate what works, learn from experience, and scale.
