What are the Hours and Dates of the B3 Stock Exchange in 2024? Complete Guide to Schedules and Holidays

B3 operates on a well-defined schedule for Brazilian investors to monitor their operations safely and with proper planning. If you need to know what time the stock exchange closes in 2024, be aware that its operation follows a specific calendar with significant variations throughout the year.

Exact Operating Hours of B3

The Brazilian stock market functions in an orderly manner with three clearly defined periods. On trading days, the main trading session occurs between 10:00 and 17:00 Brasília time. Before that, there is the pre-opening session from 9:45 to 10:00, during which orders from the previous day are registered by the system.

After the regular trading session closes, there is still the after-market, which allows trading of certain assets between 17:30 and 18:00. This period is subject to variations according to the American summer calendar and may not occur at certain times of the year.

Time Change Starting March 2024

An important change marks the year 2024: until March 10th, B3 closes at 18:00. Starting March 11th, the stock exchange’s closing time returns to the previous pattern, with closing at 17:00 and the after-market resuming from 17:30 to 18:00.

This change occurs because the American daylight saving time ends on March 10th, 2024, directly affecting the trading of certain securities in Brazil. Investors should adapt to this new schedule to avoid missing trading opportunities.

Holidays That Close the Stock Exchange in 2024

The 2024 calendar features national holidays that completely suspend B3 operations. These periods significantly impact investors’ planning:

• January 1st (Monday): New Year’s Day
• February 12th and 13th (Monday and Tuesday): Carnival, with continuous session on February 14th (Wednesday), between 13:00 and 17:55
• March 29th (Friday): Good Friday
• May 1st (Wednesday): Labor Day
• May 30th (Thursday): Corpus Christi
• November 15th (Friday): Proclamation of the Republic
• December 25th (Wednesday): Christmas
• December 31st (Tuesday): New Year’s Eve, no operations due to banking hours

Local holidays, such as São Paulo’s anniversary, do not affect the stock exchange operations, allowing investors to continue trading normally.

Impact of Time Variations on the Market

Investors should understand that time changes do not occur randomly. The synchronization between the Brazilian and American markets reflects the global integration of financial markets. International investors, exchange rate fluctuations, and oscillations in commodities like oil and metals directly influence this dynamic.

Knowing what time the stock exchange closes is essential to avoid missing trading deadlines and to take advantage of all opportunity windows. The recommendation is always to consult B3’s official channels to confirm schedules and ensure your operations are executed safely and within permitted hours.

Staying updated on B3’s operating hours in 2024 and its holidays is crucial for any investor aiming to optimize their market strategies and make more assertive decisions about when to trade their shares.
