Cocoa surplus and deficit explained: reading the global balance sheet
4 min read · Free public research
Understand production, grindings, ending stocks and the stocks-to-grindings ratio. Learn why a revised surplus is different from an immediate trading signal.
A cocoa surplus or deficit is an estimate for a defined period. It is not a live warehouse count, and it does not say where every available tonne is located. Read the components and assumptions before interpreting the headline.
A deficit uses stocks; it does not mean stocks are zero

Illustration only. Real balances use the publisher’s definitions and can contain adjustments and revisions.
In ICCO's published balance-sheet definition, the surplus or deficit is net world crop minus grindings. Net crop adjusts gross crop for loss in weight. Using the gross production headline directly can therefore fail to reproduce the published balance.
A positive balance represents a surplus under those definitions; a negative balance represents a deficit. The sign alone does not tell you whether the estimate improved or deteriorated relative to an earlier forecast.
Work through an illustrative balance
Suppose a hypothetical season begins with 1.20 million tonnes of stocks. Net production is 4.50 million tonnes and grindings are 4.60 million tonnes. The illustrative balance is minus 0.10 million tonnes, or a 100,000-tonne deficit.
In this deliberately simplified example, subtracting that deficit from opening stocks leaves 1.10 million tonnes of ending stocks. Dividing 1.10 by grindings of 4.60 gives a stocks-to-grindings ratio of about 23.9%.
These invented numbers demonstrate the arithmetic, not the current cocoa outlook. Published estimates can be revised, including their historical inputs. Use each publisher's definitions and adjustments rather than assuming this simplified identity reproduces every reported table.
Compare revisions before levels
Imagine a forecaster cuts an expected surplus from 300,000 to 100,000 tonnes. It still forecasts a surplus, but its balance has tightened by 200,000 tonnes. A deficit becoming smaller is the reverse type of revision: still negative, but less tight than previously estimated.
Build a comparison with the publisher, publication date, season, production, grindings, balance and ending stocks. Keep the previous estimate beside the new one. Do not present forecasts from different organisations as revisions to one continuous series.
Why stock coverage matters
A stocks-to-grindings ratio expresses estimated ending stocks relative to annual processing. It helps put a stock quantity into context, but it is not a map of immediately deliverable beans.
Global estimated stocks, exchange-monitored warehouse totals and certified stocks have different coverage. A change in one series does not automatically resolve a shortage or surplus in another. Check location, date and definition before treating them as interchangeable.
Turn the headline into research questions
Ask which component changed. Was production revised, were grindings reduced, or did historical stocks change? Is the estimate for the current season or the next one? What new evidence did the publisher use, and what remains uncertain?
Then compare that explanation with the dated physical reports. The aim is a traceable interpretation, rather than a rule that “surplus means sell” or “deficit means buy”. A forecast also needs to be considered against what market participants had already expected.

Putting the guide into practice
Choose one dated observation relevant to this guide and trace it back to the original source. Record the benchmark, unit and reporting period before comparing it with another figure. This turns the explanation into a repeatable research process: establish what is measured, check what changed and identify what the observation cannot tell you.
Use the database to check the neighbouring evidence. A price observation can be compared with physical availability and positioning; an inventory or arrivals observation can be checked against compatible history and demand reporting. Agreement between several observations can strengthen a hypothesis, while disagreement highlights the next question to investigate. Neither outcome removes the need to check timing and definitions.
