FX.co ★ Brazil’s IBC-Br Economic Activity Index Swings Into Contraction in March

Brazil’s IBC-Br economic activity index turned negative in March 2026, signaling a sharp reversal in short-term growth momentum. The index fell to -0.70% in March, down from a 0.60% reading in February 2026, according to data updated on 18 May 2026.

The move from positive to negative territory suggests that economic activity lost steam at the end of the first quarter, after showing expansion the previous month. Market participants and policymakers will be watching upcoming data closely to assess whether the March contraction is a temporary setback or the start of a more persistent slowdown in Brazil’s growth trajectory.
