In the shadow of Rio de Janeiro, the Brazilian city of Maricá has become a laboratory for municipal finance. With a population of about 212,000, the city launched a sovereign wealth fund in 2017 after oil royalties boosted its coffers. The fund, now worth more than R$2 billion (about $415 million), is earmarked for long‑term development projects such as a new seaport, a five‑star resort, a technology park and local entrepreneurship programs.
How the fund works
Maricá first introduced a basic income program in 2013, paying households earning less than three times the national minimum wage 230 Mumbucas (roughly $45) each month. The money must be spent locally, keeping it in circulation. A 2024 study by the Jain Family Institute found that participating families increased their income by 9%.
To protect the new revenue, the city created CODEMAR, a development corporation that invests the fund’s assets in low‑risk domestic bonds and strategic projects. Early investments include a R$1.5 billion (≈$290 million) seaport expected to create 13,000 jobs, a five‑star resort, a satellite teleport, a shopping mall, airport expansions, greenhouses and a samba school that recently reached the top competition level.
Benefits and challenges
Proponents argue the fund locks money into development rather than allowing it to disappear into the municipal budget. It also forces the city to consider non‑profit‑driven priorities such as food security and climate‑resilient infrastructure—areas the market would normally ignore.
Critics point out that a city‑run fund is smaller than state or national equivalents and still depends on larger lenders like the Brazilian Development Bank or the World Bank for big projects. Governance is another concern; because the fund is managed by city officials, a change in administration could alter investment strategies or even the fund’s legal framework.
What the United States can learn
President Trump’s 2025 executive order directing Treasury and Commerce to explore a national sovereign wealth fund reflects a growing interest in using surplus revenues for long‑term fiscal health. Yet, as Paul Katz of the Jain Family Institute notes, most U.S. cities lack the resource surplus that fuels Maricá’s model. Alaska’s Permanent Fund and Texas’s Economic Stabilization Fund remain the only domestic examples, both tied to mineral or oil royalties.
Without a comparable surplus, U.S. municipalities would need a federal vehicle—similar to the proposals from Senator Bernie Sanders and the Trump administration—to channel funds into local projects. Until such a mechanism exists, city leaders can still draw inspiration from Maricá’s focus on job‑creating infrastructure, local entrepreneurship and a basic‑income safety net.
Looking ahead
Other Brazilian municipalities, from the right‑leaning beach town of Ilhabela to the state of Paraná, have launched their own funds, showing the concept can cross political lines. For American cities, the key takeaway is the importance of protecting long‑term investment assets from short‑term political swings while seeking partnerships with state and federal agencies to fund larger projects.
