Business & Commerce

São Paulo, Brazil's largest city and South America's primary financial and commercial hub, operates on Brasília Time (BRT, UTC−3) year-round — Brazil abolished daylight saving time in April 2019, ending the decades-old seasonal BRST (UTC−2) adjustment. Since that change, BRT (UTC−3) is fixed for all of Brazil's major economic centers. At UTC−3, São Paulo is three hours behind London (GMT) and two hours ahead of New York (EST) in winter, with its business day running from roughly 8:00 AM to 6:00 PM BRT. The B3 (Brasil Bolsa Balcão) in São Paulo is by far the largest stock exchange in Latin America and one of the twenty largest in the world by total market capitalization. BRT aligns exactly with Buenos Aires (ART), meaning South America's two largest financial cities operate on a shared clock — a significant convenience for regional business coordination and cross-border investment flows.
