Brazil coffee harvest delayed by heavy rains, tightening global Arabica supply

Unseasonal heavy rainfall in June across Brazil's main Arabica coffee regions stalled the 2026/27 harvest, with only about 29% of the projected area harvested—well below the 34% recorded a year earlier and historic averages. The excess moisture caused fruit drop, mold growth and raised concerns over bean quality, potentially reducing the supply of specialty coffee and threatening the next season's yield.

The market reacted with Arabica futures falling on the New York exchange while Robusta contracts rose on London, reflecting traders' reassessment of Brazilian supply. Prices remain volatile as analysts watch the pace of the harvest, producers' cautious sales stance, and the ongoing climate outlook. Brazil's dominant role in global Arabica production means any delay or quality issue reverberates through international coffee markets.

Consultancies warn that persistent humidity could prompt early flowering, exposing the 2027/28 crop to frost or drought later in the year, further jeopardising Brazil's contribution to the worldwide coffee balance.
