Brazil abolished daylight saving in 2019 and the United States did not, so B3 shifts its whole grid by an hour twice a year to stay aligned with New York: this 17:00 close took effect 9 March 2026 (Oficio Circular 005/2026-PRE) and from 3 November 2025 until 6 March 2026 the same session closed at 18:00. Expect it to move back when US clocks change on 1 November 2026. Continuous trading ends at 16:55; 17:00 is the end of the closing call.",
