On Monday, September 7, 2026, Brazil’s Independence Day holiday, there will be no trading in the main markets operated by B3. The interruption includes stocks, real estate investment funds (FIIs), ETFs, BDRs, derivatives, private fixed income and fixed-income ETFs. Tesouro Direto will also have no trading or investment confirmation. According to B3, activities will resume normally on Tuesday, September 8.
This is a specific scope covering B3 infrastructure and Tesouro Direto. The notice should not, by itself, be used to infer how banks, Pix or other financial services outside that scope will operate.
Quick answer: what stops on September 7 and resumes on September 8
| Operation or service | September 7 | September 8 |
|---|---|---|
| Stocks, FIIs, ETFs and BDRs | No trading | Normal B3 operations |
| Listed derivatives | No trading | Normal B3 operations |
| Private fixed income and fixed-income ETFs | No trading | Normal B3 operations |
| Securities lending | No trading | Normal B3 operations |
| Post-trade for listed and organized OTC segments | No registration, clearing, settlement, collateral movement or Central Depository activities, as covered by the applicable calendar | Normal resumption |
| Tesouro Direto | No trading or investment confirmation | Normal resumption |
What B3 suspends for the holiday
The notice published by B3 on September 3, 2026 states that, because of the national holiday, there will be no trading session on September 7 for equities and several other markets. The published list includes stocks, real estate investment funds, ETFs, BDRs, derivatives, private fixed income and fixed-income ETFs.
B3’s Trading Calendar further specifies that securities lending will not trade in the listed segment. For post-trade flows covered by the calendar, procedures such as contracting, clearing, settlement, collateral movements and certain Central Depository movements are also suspended.
In practical terms, the holiday affects more than the trading screen: it also reaches infrastructure stages that register, clear, settle and hold assets for the segments specified by B3. That does not mean every single system related to the B3 group stops; the calendar sets different rules for different segments and infrastructures.
What happens to Tesouro Direto on September 7?
For investors in Brazilian government bonds through Tesouro Direto, the official guidance is straightforward: there will be no trading or investment confirmation on September 7. The day therefore should not be treated as a normal session for buying or selling securities within the program.
The same communication states that normal activity returns on September 8. For an investment decision that depends on an actual Tesouro Direto transaction, the operational reference is the Tuesday after the holiday.
Fixed income: the holiday affects more than Tesouro Direto
It is important to separate Tesouro Direto from other fixed-income products. B3 also states that there will be no trading in private fixed income or fixed-income ETFs in the listed segment. The exchange’s operational calendar also provides for interruptions in registration, deposit, collateral and settlement activities in OTC segments covered by the holiday rules.
This helps avoid a common misunderstanding: “fixed income” is not a single market or a single platform. Tesouro Direto, private securities, fixed-income ETFs and registration systems have their own flows, although several are affected by the same holiday across B3 infrastructure.
What resumes on September 8
B3 states that its activities will resume normally on Tuesday, September 8, 2026. For investors, that means the return of the regular session in markets that had no trading the previous day and the resumption of Tesouro Direto, subject to the usual schedules and rules of each environment.
If your transaction depends on a specific stage — such as settlement, collateral movement, OTC registration or investment confirmation — check B3’s detailed operational calendar and, when applicable, the information from the institution through which the order was placed.
What this notice does not say about banks or Pix
B3’s notice addresses the operation of its markets, clearing houses, depository and Tesouro Direto. It is not a general banking-system calendar and should not be extrapolated to claim, without another source, whether branches, transfers, Pix, cards or services from a particular financial institution will be available.
For those cases, the right source is the rule for the specific service and the communication from the responsible bank or institution. The practical benefit is to keep two questions separate: “Are B3/Tesouro markets trading?” and “Does my bank or payment method work?”.
How to plan around the holiday
- If you want to trade B3 assets: treat September 7 as a non-trading day for the markets listed in the official notice.
- If you want to trade through Tesouro Direto: do not expect trading or investment confirmation on the holiday.
- If an important settlement or operational stage is involved: check B3’s detailed calendar for the relevant segment.
- For September 8: the official information is that activities resume normally.
- For banks and Pix: consult specific sources; do not use B3’s calendar as a substitute.
