Brazil’s B3 Stock Market Adjusts Trading Hours Following US Daylight Saving Time Change
B3, Brazil’s main stock exchange, announced new trading hours effective Monday, March 10, 2025. The schedule adjustment responds to the start of Daylight Saving Time in the United States, which shifts market closing times in Brazil.
The standard market will now close at 5:00 PM, returning to its regular schedule. After-market trading for stocks will operate from 5:30 PM to 6:00 PM. Opening times remain unchanged at 10:00 AM for regular sessions.
Order cancellations will occur between 9:30 AM and 9:45 AM in the morning. Evening cancellations will happen between 5:25 PM and 5:30 PM after the market closes.
Brazilian Depositary Receipts (BDRs) will follow the same schedule as the stock market. These instruments represent shares of foreign companies traded on the Brazilian exchange.
Fixed income Exchange Traded Funds (ETFs) will operate from 10:00 AM to 5:15 PM. Variable income ETFs start slightly later at 10:05 AM and also end at 5:15 PM.
Derivatives markets follow varied schedules depending on the asset type. Futures contracts and options related to commodities will trade from 9:00 AM until 3:00 PM or 3:20 PM.
B3 Trading Schedule Adjustments for Brazilian Investors
Stock index-based futures and options will begin at 9:00 AM and close between 5:10 PM and 6:25 PM. Futures contracts for stocks and units start at 9:00 AM and finish at 5:55 PM.
Commercial dollar futures and options will trade from 9:00 AM until 6:00 PM or 6:30 PM. Bitcoin futures maintain a 9:00 AM to 6:30 PM schedule.
