Officially the Brazilian harvest year is from July to June.
Below are the exports from July to September.
Consider that:
1) coffees were exported from the 2020/21 crop , due to remaining stocks which I estimate to be close to 5 million bags on July 1, 2021.
2) Coffee from the 2021/22 harvest was exported because it was bought in futures and delivered now in July, August and September. So there is a greater flow of sales and deliveries at the beginning of the harvest.
Finally, Brazilian exports should decrease by about 15/17 million bags in the harvest year from July 2021 to June 2022.
