How to read it. Funds are managed money (hedge funds and CTAs). The shaded band is the middle 80% of weekly readings over 15 years; outside it, the position is unusual for this market. Heavy fund length leaves fewer new buyers, and it has to be unwound one day.

How to read this. A bag of Brazilian arabica quoted in reais is the board in cents, converted at the day's rate, times a basis that carries the origin differential, cup and defect quality, freight and tax treatment. Those three multiply to the quote exactly, so a change in the quote can be split among them with nothing left over. Attribution is symmetric across the three factors, which is why the parts sum to the whole no matter which one you vary first.

What it is not. This is an accounting identity, not a causal model — it says how much each term moved, never which one moved the others, and a weaker real routinely widens the differential rather than acting independently of it. It is also not a farmgate price: CCCMG quotes T6 dura delivered to São Paulo, between companies, ex-tax and discounted by the NPR rate, so freight and delivery level sit inside the basis term. The series is month-end spot from May 2016 throughout — deliberately not the reference farm-price CSV, which splices monthly averages to month-end spot at January 2017 and would book that definition change as a price move.

How to read it. The crop calendar decides whether a reading is news: rain matters at flowering, dryness helps at harvest. Stress z is the mean water-stress z-score of the last three dekads (positive = drier); inside ±0.5 is near normal. Origins outside a critical stage are context.
