B3 moves into digital assets: a tokenization platform and a BRL-linked stablecoin that could reshape Brazilian markets

Big step: B3 bets on tokenization and a BRL stablecoin

B3 (B3SA3), Brazil’s main stock exchange, has announced plans to roll out a tokenization platform and a Brazilian real–linked stablecoin. The exchange says the move will let traditional securities, funds and other assets be issued and traded in token form on its systems. For markets, that means the place where stocks and bonds are listed is trying to become the gatekeeper for a new digital infrastructure — a change that could speed settlement, widen access to fractional ownership and create fresh trading layers tied directly to the local currency.

The announcement is not a narrow tech experiment. When a market operator the size of B3 moves into tokenization and stablecoins, it changes the math for banks, brokers, asset managers and regulators. Investors should treat this as an infrastructure story with potential knock-on effects for liquidity, custody services and the way fractional or cross-border trades happen.

How this could alter market plumbing and trading

At its most basic, tokenization turns rights to an asset — a share, a bond or a piece of a building — into a digital token that can be traded much like a cryptocurrency. If B3 runs that token layer, trading could shift in two ways. First, settlement could become faster and operate around the clock, reducing the time and risk between a trade and ownership change. Second, tokenized versions of listed products could create parallel markets where liquidity pools differ from the classic exchange order book.

For B3’s own business the upside is clear: the exchange can capture new fees from issuance, custody and secondary trading of tokens. It also positions B3 as the trusted hub for asset digitization in Brazil — something institutional clients may prefer over offshore platforms. But that same position creates new responsibilities. If token trading grows, B3 will need systems to manage off-chain events (dividends, corporate actions) and make sure tokenized instruments match their underlying securities.

Exchange-traded products (ETPs) and funds stand to benefit from faster settlement and easier fractionalisation. Retail investors could buy tiny slices of assets that were previously hard to reach. Yet there’s a trade-off: liquidity in token markets will depend heavily on market makers, custodians and the stablecoin rails that power payments between participants.

What the BRL-linked stablecoin will likely look like

B3’s planned stablecoin aims to be priced against the real. The simplest and most credible design would be a fiat-backed model: each token is backed one-for-one by real deposits or short-term Brazilian government paper held in regulated custody. That approach gives a straight line from token to local currency and makes it easier for banks and the central bank to monitor reserves.

Other models exist — algorithmic reserves or hybrid structures — but those raise more trust and regulatory questions. For an exchange-backed coin meant to support securities trading, Brazil’s authorities will likely prefer a clear reserve model with regular audits, transparent issuance/redemption rules, and strong custody of the underlying cash or bonds.

Operationally, issuers would mint stablecoins when someone deposits reais and burn them on redemption, creating a direct on/off ramp between bank accounts and the token layer. That setup lowers settlement friction for token trades, but it concentrates counterparty and custody risk in the reserve keeper and the systems that verify redemptions.

Assets B3 is likely to tokenize and what that changes

B3 has a broad menu at its disposal: listed equities, corporate and government bonds, investment funds, and even real estate. Tokenized government bonds could be especially powerful in Brazil, where a deep local bond market is a backbone of fixed-income investing. Tokenization could allow smaller investors to access slices of high-quality paper or to trade bonds more frequently with lower minimums.

For equities, tokenized shares can enable instant fractional ownership, which matters for high-priced listings or for funds that want fine-grained exposure. Real estate and private assets are natural fits too: tokens make it easier to slice property into tradable pieces and to manage ownership records on a digital ledger.

Settlement is the big operational shift. Instead of waiting for central custody and batch processing, transfers could be near-instant and programmable. That reduces settlement risk but raises new questions about cross-system reconciliation and how token records map to legal ownership under Brazilian law.

Regulation: Central Bank, CVM and the guardrails that matter

Brazil’s Central Bank and the securities regulator, CVM, will be central to how this plays out. The Central Bank has already shown a strong interest in payment tokens and digital currency oversight; it runs PIX, Brazil’s fast-pay system, and it will want clear controls over reserve assets backing any BRL stablecoin. The CVM will focus on whether tokenized securities meet existing investor protection rules, prospectus requirements and custody standards.

Expect requirements on AML/KYC, custody segregation, reserve audits and incident reporting. Licensing could be needed for the stablecoin issuer, the reserve manager and custodians holding tokenized assets. That regulatory attention is a double-edged sword: it raises compliance costs but also increases trust, which is crucial if institutional clients are to adopt tokenized products.

Investor takeaways: where the opportunities and risks sit

This is a structural story, not a short-term trade. If B3 delivers a regulated, well-backed BRL stablecoin and a robust token platform, it could unlock faster settlement, new retail access and fresh fee streams for the exchange. That is positive for investors who favour long-term infrastructure winners.

But the risks are real. Custody and reserve counterparty risk will be front and center: who holds the reais, who audits the reserves, and how quickly can users convert tokens back to cash? Liquidity risk is another worry — token markets need market makers and regulation that supports fair access. Finally, the regulatory timeline will shape adoption: pilots may run for months or years before full commercial launch.

Watch the rollout schedule, the reserve model disclosures, and early pilot participants. Those signals will tell you whether this is a careful modernization of Brazil’s market plumbing — or an ambitious move that still has heavy execution and regulatory hurdles to clear.
