Arabica's exchange-stock scarcity has not disappeared, but the mechanism capable of relieving it has arrived. ICE certified stocks remain near multi-decade lows at roughly 220,000 bags, yet more than 62,000 bags of Brazilian coffee have reached exchange depots for grading, major trading houses are preparing far larger December deliveries, and Brazilian exports to Belgium — where most ICE-certified stock sits — rose 245.3% year on year in August. Managed money has started moving in the same direction, cutting net length by 4,620 contracts while arabica fell to a ten-week low. The scarcity remains. The pipeline capable of ending it is becoming visible.
TL;DR
- ICE certified arabica stocks remain exceptionally depleted, at roughly 220,000 bags, so the physical buffer has not yet been rebuilt.
- More than 62,000 Brazilian bags have already arrived at exchange depots for grading, providing the first visible pipeline into those depleted stocks.
- Major traders are preparing potential December deliveries of roughly 150,000–200,000 bags each. If sufficient coffee passes certification, exchange stocks could rise materially.
- Brazilian coffee exports to Belgium rose 245.3% year on year in August. Antwerp holds the majority of ICE-certified arabica inventory, making that flow directly relevant to exchange availability.
- Managed money reduced net length by 4,620 contracts to +22,109 in the week to 8 September, through both long liquidation and new short selling.
- Arabica closed at $2.8815/lb on 10 September after touching $2.8210, a ten-week low, providing market-price confirmation that expectations around improving supply and favourable Brazilian flowering are already being reflected.
- Brazil's 2026/27 crop is large but estimates are unusually dispersed, from CONAB at 66.7 million bags to Marex at 75.9 million.
- Attention is already moving towards the next Brazilian crop. Early flowering conditions have been favourable, but a rapidly strengthening El Niño makes subsequent rainfall and fruit set important monitoring variables.
- NOAA now sees a greater than 90% probability of a very strong El Niño, with a 75% chance that October–December reaches a strength exceeding previous events dating back to 1950. NOAA explicitly cautions that expected regional impacts are not guaranteed.
- The coffee squeeze has therefore moved into a confirmation phase: the critical question is whether incoming Brazilian coffee actually passes grading and rebuilds certified stocks.
The Scarcity Is Still Real
Coffee's summer rally was fundamentally a deliverable-availability trade.
ICE certified arabica inventories fell towards 220,000 60kg bags as Brazilian coffee failed to reach exchange warehouses quickly enough to replace withdrawals. That is an unusually depleted buffer for a market accustomed historically to holding substantially more certified inventory.
The distinction between global supply and exchange availability is important. A large Brazilian crop does not automatically resolve a shortage of coffee deliverable against ICE futures. Coffee must be exported to an approved warehouse, satisfy exchange quality requirements and complete the certification process before it becomes part of certified stocks.
That process created the scarcity premium through the summer. It also explains why expectations of a comfortable 2026/27 global balance did not immediately eliminate high arabica prices: coffee could be adequately supplied globally while remaining scarce in the particular locations and specifications required for delivery against the futures contract.
That scarcity has not yet disappeared. At roughly 220,000 bags, certified stocks remain extremely low.
What has changed is the flow towards them.
Brazilian Coffee Is Heading for the Exchange
More than 62,000 bags of Brazilian arabica had arrived at exchange depots for grading by 11 September. Major trading houses are also preparing substantially larger quantities for possible delivery against the December contract, with individual programmes reportedly around 150,000–200,000 bags.
Those numbers should not be treated as certified inventory yet. Coffee presented for grading can fail to meet ICE specifications, and proposed December deliveries are intentions rather than completed transfers. The amount ultimately added to certified stocks could therefore be materially smaller than the headline pipeline.
But the direction of travel is significant.
Brazilian exports to Belgium increased 245.3% year on year in August. Belgium matters because Antwerp is the dominant location for ICE-certified arabica inventory. The export increase therefore provides physical evidence consistent with coffee being repositioned towards the exchange system rather than merely an expectation that it eventually will be.
If the coffee already awaiting grading is approved, certified availability begins improving from an exceptionally low base. If the larger December programmes subsequently arrive and pass certification, the change could be much more substantial.
The important signal is therefore no longer the absolute inventory number alone. It is the conversion rate from Brazilian export flow, to exchange warehouse, to grading, to certified stock. That chain will determine whether the summer scarcity premium actually unwinds.
Funds Have Started Moving First
Managed-money positioning has already become less bullish.
In the CFTC report for positions held on 8 September, Coffee C managed money held 37,050 longs and 14,941 shorts, leaving a net long of +22,109 contracts. That was down 4,620 contracts from +26,729 the previous week.
The mechanics are more important than the headline reduction. Funds liquidated 2,950 existing longs while adding 1,670 shorts, so both sides of the book moved in a bearish direction. Coffee is not simply experiencing slower bullish accumulation; some existing bullish exposure is being removed while new bearish exposure is being established.
That distinguishes it from markets such as sugar, where net positioning can decline or increase because one side of the book is being covered rather than because directional conviction is changing.
It also separates coffee from the broader agricultural positioning pattern. Corn and soybeans attracted substantial new long buying during the same CFTC reporting week, while coffee and cocoa deteriorated. Coffee's positioning shift is therefore commodity-specific rather than evidence of general agricultural fund liquidation.
Price has followed. Arabica closed at $2.8815/lb on 10 September after touching $2.8210 intraday, its lowest level in ten weeks. The chronology matters: the CFTC snapshot is dated 8 September, the price low came on the 10th, and the Reuters report detailing Brazilian arrivals at exchange depots followed on the 11th. The market is therefore beginning to price improved availability before the anticipated pipeline has actually become certified inventory.
The timing is consistent with the physical story. Managed money began reducing exposure as the market moved from a scarcity defined by depleted exchange inventory towards one where Brazilian supply is increasingly capable of reaching that inventory.
Brazil Changes the Supply Calculation
The coffee reaching Europe originates from a much stronger Brazilian production year, although estimates of its precise size remain unusually wide.
USDA's Brazil post forecasts 2026/27 production at 71.9 million 60kg bags, comprising 47.5 million bags of arabica and 24.4 million bags of robusta. Private estimates are higher: StoneX 75.3 million bags, Sucafina 75.4 million and Marex 75.9 million. At the other end of the range, CONAB estimates 66.7 million bags.
The spread is substantial. CONAB and Marex differ by more than nine million bags, while the three private estimates cluster tightly between 75.3 million and 75.9 million. That makes it inappropriate to treat any single estimate as settled, but the disagreement is principally about the scale of the Brazilian recovery rather than whether production has recovered.
USDA's composition is also important for the ICE story. Its Brazil post expects arabica production of 47.5 million bags, up from an estimated 38 million in 2025/26. That provides the physical supply from which depleted exchange stocks can potentially rebuild.
It also changes how low ICE inventories should be interpreted. When Brazilian production was constrained and exchange stocks were declining, low certified inventory reinforced a broader scarcity story. With Brazilian production recovering strongly, the same low inventory increasingly represents a distribution and certification bottleneck.
Those bottlenecks can still produce significant price moves, but they are potentially faster to resolve than an outright production shortage. This is why the Brazilian grading pipeline matters more now than another comparison showing that ICE stocks remain historically low. The market already knows the stocks are depleted. The question is whether they remain depleted once a larger Brazilian crop reaches the certification system.
The Market Is Already Moving Towards the Next Crop
As the current harvest reaches its final stages, the forward risk is shifting towards Brazil's next arabica cycle.
The initial signal has been favourable. Dealers reported on 10 September that abundant rainfall had supported flowering for Brazil's 2027 crop, part of the fundamental backdrop as arabica fell to its lowest level in ten weeks. That does not establish the next crop's eventual size — flowering still has to translate into successful fruit set — but there is currently little evidence of the immediate flowering stress that would be required to revive the scarcity thesis through the next Brazilian cycle.
The weather risk nevertheless deserves close monitoring because El Niño is strengthening rapidly. NOAA's 10 September ENSO update gives a greater than 90% probability of a very strong El Niño during Northern Hemisphere autumn and winter 2026/27. More unusually, it assigns a 75% probability that the October–December event reaches a strength exceeding previous El Niño episodes dating back to 1950 under its current RONI measure.
That is a material climate signal. It is not, by itself, a directional coffee signal.
NOAA explicitly cautions that even an event of this magnitude increases the probability of characteristic El Niño impacts rather than guaranteeing them. The relevant coffee variable is therefore not whether El Niño exists, but what actually happens to rainfall across Brazil's arabica belt.
For the market, the monitoring sequence should therefore be rainfall, then flowering quality, then fruit set — rather than El Niño classification followed by assumed production loss.
If rainfall remains adequate and flowering converts successfully into fruit, the next crop begins against a much more comfortable supply backdrop. If conditions deteriorate materially during flowering or fruit set, the current lack of an inventory buffer becomes important again.
Scarcity Has Become a Pipeline Question
The coffee market is therefore moving between two different forms of tightness.
The first was physical and immediate: exceptionally low certified stocks combined with insufficient new coffee reaching ICE warehouses. The second is conditional: certified stocks are still exceptionally low, but enough Brazilian coffee is now moving towards the exchange to create a credible replenishment mechanism.
That is not the same as saying the squeeze is over. More than 62,000 bags awaiting grading cannot be counted as certified stock. Proposed deliveries of 150,000–200,000 bags per trading house cannot be counted until they arrive, pass inspection and enter the exchange system.
But markets price expected availability before the inventory appears.
The transition is now visible across physical flows, positioning and price. Brazilian coffee is moving towards ICE certification, managed money is simultaneously liquidating longs and adding shorts, and arabica touched $2.8210/lb on 10 September, its lowest level in ten weeks. None proves that certified stocks will rebuild, but all three are moving in the direction expected if the summer scarcity premium is beginning to unwind.
The next test is unusually observable. If certified stocks begin rising materially through September and into the December delivery period, the exchange scarcity thesis will have weakened substantially. If Brazilian coffee fails certification, deliveries are smaller than expected or certified stocks continue declining despite the incoming flow, the market will have evidence that the scarcity is more persistent than current positioning implies.
Outlook
Base case: Brazilian coffee increasingly reaches the ICE certification system as the 2026/27 harvest moves through the supply chain. Certified stocks begin recovering from their exceptionally low base, reducing the deliverable-scarcity premium. Managed-money exposure remains vulnerable to further reduction if stock rebuilding becomes visible.
Upside risk: The anticipated Brazilian deliveries fail to translate into certified inventory, either because volumes are smaller than expected or because substantial quantities fail grading. At the same time, adverse rainfall or poor fruit set could weaken expectations for Brazil's next arabica crop. With certified stocks still around 220,000 bags, the market has little inventory buffer against renewed disruption.
Downside risk: The existing 62,000-plus bag grading pipeline converts successfully into certified stock and larger December delivery programmes follow. A visible recovery in exchange availability alongside strong Brazilian production would remove the principal physical constraint that supported the summer scarcity premium.
What would change the view: Continued declines in certified stocks despite substantial Brazilian arrivals would challenge the assumption that the squeeze is easing. Conversely, sustained stock rebuilding combined with successful Brazilian flowering and further managed-money liquidation would provide much stronger confirmation that the deliverable-scarcity cycle has turned.
Key Risks
- Certified stocks remain exceptionally depleted. The expected replenishment has not yet occurred at sufficient scale to remove the inventory risk.
- Arrivals are not certified stocks. More than 62,000 Brazilian bags awaiting grading may not all satisfy exchange requirements.
- Proposed December deliveries are not guaranteed. Reported programmes of 150,000–200,000 bags per trading house represent potential supply rather than completed certification.
- Brazilian crop estimates remain unusually dispersed. CONAB stands at 66.7 million bags, USDA at 71.9 million, while StoneX, Sucafina and Marex cluster between 75.3 million and 75.9 million. The roughly nine-million-bag range is material to the scale of available export supply.
- El Niño is unusually strong but its regional consequences are uncertain. Climate classification should not be treated mechanically as a forecast of Brazilian coffee production.
- Managed money remains net long. At +22,109 contracts, further liquidation could amplify a fundamentally driven decline even after the position has already been reduced.
Intelligence Monitoring Points
- ICE certified arabica stocks: whether the roughly 220,000-bag base begins rising materially.
- Brazilian coffee awaiting grading: how much of the 62,000-plus bag pipeline receives certification.
- December delivery programmes: whether the reported 150,000–200,000-bag programmes translate into actual exchange deliveries.
- Brazil-to-Belgium exports: whether August's 245.3% year-on-year increase persists.
- CONAB and private crop estimates: whether the roughly nine-million-bag spread narrows as the harvest completes.
- Brazilian rainfall and flowering: observed conditions across the arabica belt rather than the El Niño classification alone.
- Fruit set: the next physical confirmation of 2027 crop potential following flowering.
- CFTC positioning: whether managed-money net length continues falling from +22,109 and whether the move remains driven by both long liquidation and new shorts.
- Arabica price response: whether improving deliverable availability produces further weakness or depleted stocks continue supporting the market.
FAQ
Is the coffee squeeze over? Not yet. ICE certified arabica stocks remain around 220,000 bags. What has changed is that Brazilian coffee is now reaching exchange warehouses for grading, creating a credible mechanism through which those stocks could rebuild.
How much Brazilian coffee is heading towards ICE? More than 62,000 bags had already arrived at exchange depots for grading by 11 September. Major trading houses are also reportedly preparing potential deliveries of roughly 150,000–200,000 bags each for December. Those volumes should not be treated as certified inventory until they pass grading.
What are coffee funds doing? Managed money reduced net Coffee C length by 4,620 contracts to +22,109 in the week to 8 September. Funds cut 2,950 longs while adding 1,670 shorts, making the mechanics bearish on both sides of the book.
How large is Brazil's coffee crop? Estimates are unusually dispersed. CONAB forecasts 66.7 million 60kg bags and USDA's Brazil post 71.9 million, while StoneX, Sucafina and Marex cluster between 75.3 million and 75.9 million. All describe a recovery; they disagree about its scale.
Why does Belgium matter? Antwerp holds the majority of ICE-certified arabica stocks. Brazilian exports to Belgium increased 245.3% year on year in August, making that trade flow directly relevant to the potential rebuilding of exchange inventories.
Does El Niño mean Brazil's next coffee crop will be damaged? No. NOAA expects an unusually strong El Niño, but explicitly cautions that typical regional impacts are not guaranteed. Dealers reported favourable flowering rainfall on 10 September. For coffee, observed rainfall, flowering and fruit set across Brazil's producing regions are more useful signals than the ENSO classification by itself.
What matters most now? Whether Brazilian arrivals become certified inventory. If ICE stocks begin rebuilding materially, the summer scarcity premium has a clear mechanism for unwinding. If stocks remain depleted despite substantial arrivals, the physical tightness is more persistent than current positioning suggests.
