Nubank and MercadoLibre BDRs Set for Ibovespa Inclusion in 2027 Rule Change
Brazil's B3 exchange will allow Brazilian Depositary Receipts of domestically founded, foreign-listed companies to enter its benchmark index starting in 2027.
Domestically founded companies that chose to list their shares on foreign exchanges like the New York Stock Exchange or Nasdaq are set to become eligible for Brazil's benchmark stock index. This structural adjustment will bring some of Latin America's largest technology and financial players into the local index framework, altering how domestic institutional portfolios interact with these foreign-listed entities.
On September 8, 2026, Brazil’s B3 exchange announced a methodological change that permits Brazilian Depositary Receipts (BDRs)—locally traded certificates representing shares listed abroad—to enter the benchmark Ibovespa index. According to the official B3 announcement, the transition is scheduled to take effect during the first half of 2027. The update means that passive index funds and local institutional portfolios tracking the Ibovespa will incorporate these receipts into their eligible investment universe.
Historically, the Ibovespa has been heavily weighted toward legacy industrial and commodity sectors, dominated by state-backed oil producer Petrobras and mining giant Vale. By excluding companies that listed directly abroad, the index did not fully reflect the modern, consumer-facing digital segments of the Brazilian economy. Under the new rules, the total aggregate allocation of these foreign-listed BDRs will be capped at 10% of the index's theoretical portfolio. The B3 established this 10% ceiling to ensure the index remains compliant with local regulatory investment limits governing pension funds and institutional portfolios.
The regulatory shift follows a series of modernizing reforms by Brazilian financial authorities. The B3 highlighted that recent regulatory updates—specifically the Securities and Exchange Commission of Brazil (CVM) Resolution 175 and National Monetary Council (CMN) pension guidelines—provided the legal framework and institutional parameters necessary to integrate these foreign-listed structures into the country's main index.
Market Implications
For global asset managers and institutional investors, this index inclusion will alter local portfolio allocations. Passive index-tracking funds inside Brazil will need to purchase the underlying BDRs to match the updated Ibovespa composition. While the B3 has not yet confirmed the final list of additions, major US-listed players such as digital bank Nu Holdings, financial services firm XP Inc., and e-commerce giant MercadoLibre are among the primary candidates meeting the index's standard liquidity and trading volume criteria.
The inclusion of these high-growth financial and technology players is expected to diversify the local benchmark. For international investors holding the US-listed parent shares of these companies, the change establishes a direct structural link to Brazil's domestic indexing flows. The exact timeline and final list of eligible BDRs will be determined by the B3 in subsequent operational circulars leading up to the first-half 2027 index rebalancing.
