This is an illustrative sample. It describes the shape of a GARI commodity briefing — what each part of one is for — rather than any market, and it reports no observation of its own.
A commodity briefing opens with the move: what changed over the period, and whether it was inside or outside the band the engine had published beforehand. The band matters more than the move. A briefing that only reported the direction would be a headline; the discipline is to say where the outcome sat relative to what we said would happen.
The second part attributes the change. The engine separates the drivers it can measure — inventories, the rate outlook, positioning, seasonality — and reports how much weight each one carries, with the honest remainder left unattributed. In an illustrative move from €100 to €110 per tonne, the briefing's job is to say which of those drivers carried the ten euros and how confident we are in the split, not to assert a single cause.
The third part is the reading for a decision-maker, written twice: once for a buyer, for whom the top edge of the band is the number that breaks a budget, and once for a trader, for whom the gap between the median and that edge is the position. The last part is dated and kept, so a reader can come back later and check whether we were right.
