Brazil's National Treasury and the Ministry of Environment and Climate Change published the results of the fourth Eco Invest Brasil auction, approving BRL 3.1 billion in catalytic public capital under the main line to support BRL 13.2 billion of investment in bioeconomy, sustainable tourism and infrastructure. About BRL 9 billion, or roughly 70% of the total expected investment, is set to go to projects in the Legal Amazon. This is the first round of the program to incorporate pillars of the National Bioeconomy Development Plan. Eight financial institutions submitted bids. Demand reached BRL 7.1 billion of public catalytic capital in the main line, with potential to mobilize BRL 29.3 billion of eligible investment, while the additional public resources line drew BRL 5.3 billion of demand and approved about BRL 2.5 billion, with Banco do Brasil, BTG Pactual, Bradesco and ABC Brasil selected. Under the program's blended finance structure, the National Treasury lends to banks at 1% a year and requires at least BRL 3 of private capital for each BRL 1 of public funding, with at least 60% of that private funding coming from foreign investors. Of the BRL 13.2 billion total, BRL 7.2 billion is expected from external markets and BRL 2.9 billion from domestic markets. Auction rules required all infrastructure funding to be directed to the Legal Amazon and at least one quarter of each portfolio to the region, with about BRL 7.9 billion of the Amazon allocation earmarked for infrastructure. The auction also introduced an educational counterpart requiring participating banks to spend each year, from their own resources, an amount equal to 1% of the non-amortized balance of the main line on research, training and technology entrepreneurship through science and technology institutions. The first-year amount could reach BRL 178.3 million, including BRL 44.6 million reserved for the Legal Amazon. Use of funds will be subject to an independent financial audit and a second party opinion, with validated data expected in the first half of 2028, while project progress will be tracked through the public Monitor Eco Invest platform.
