Coffee Rebounds, but Brazil’s Crop Quality Complicates the Supply Outlook (25 September 2026)

Coffee prices recovered sharply on Friday, although the move was not sufficient to reverse the losses accumulated during the week. The more important development is taking place away from the futures screen, where the Brazilian harvest is increasingly presenting two different stories: a large crop in terms of headline production, but potentially a considerably smaller pool of coffee capable of meeting higher commercial and exchange-quality requirements.

Official estimates continue to point to substantial Brazilian supply. At the same time, unusually large quality discounts, reports of weather-related deterioration, certification difficulties and low exchange inventories suggest that the availability of usable coffee may be considerably tighter than the headline crop figure alone implies. For the market, this distinction is becoming increasingly important. The central question is no longer simply how many bags Brazil harvested, but how many bags can be economically recovered, processed to acceptable standards and delivered into the channels where buyers need them.

Arabica rebounds from oversold conditions

New York arabica recovered strongly on Friday. December futures settled at 278.60 cents/lb, up 3.25 cents or 1.18%, after trading between 274.25 and 284.30 cents. Volume reached 23,139 contracts, up substantially from the previous session. Despite Friday's recovery, December still finished the week 1.90 cents lower, a decline of approximately 0.68%.

The price action nevertheless deserves attention. After briefly trading below 270 cents earlier in the week, the market recovered above the psychologically and technically important 275-cent area and subsequently reached a seven-session high above 284 cents on Friday. The inability of sellers to extend the decline below 270 cents suggests that substantial selling pressure had already been absorbed. With December having fallen from approximately 335.50 cents on August 25 to 278.60 cents, the contract remains roughly 17% below its late-August level, leaving arabica deeply corrected but not yet technically reversed.

Friday also illustrated that overhead selling remains present. December reached 284.30 cents before retreating almost six cents from the high into settlement. Buyers therefore successfully defended the lower market, but they have not yet demonstrated sustained control above 280 cents. A more convincing recovery would require the market to hold above this area and begin converting former resistance into support.

Robusta posts a stronger recovery

London robusta also recovered sharply on Friday. November futures gained $77/t, or 2.34%, to $3,367/t, after trading between $3,257 and $3,375. Trading volume increased to 28,984 contracts. Unlike arabica, robusta finished very close to its daily high, indicating stronger buying into the close, although November remained $29/t lower on the week, equivalent to a decline of approximately 0.85%.

The November/January spread strengthened to $25/t from $18/t, while November/March widened to approximately $46/t. The stronger nearby structure contrasts with the continued rebuilding of exchange inventories. Robusta certified stocks have risen to approximately 5,398 lots, their highest level in around ten months. At ten tonnes per ICE robusta lot, this represents roughly 53,980 tonnes of certified coffee.

The combination suggests that Friday's rally was not driven purely by an immediate physical shortage. Position adjustment and short covering likely contributed to the move after the substantial decline of recent weeks. The stronger spread structure is worth monitoring, but the simultaneous increase in certified stocks argues against interpreting the move as clear evidence of an acute nearby supply squeeze.

Brazil has a large crop, but the usable crop may be smaller

Brazil's 2026 harvest remains the central fundamental issue. Conab's latest estimate places national coffee production at approximately 67.6 million 60-kg bags, including around 48.2 million bags of arabica and 19.4 million bags of conilon. At face value, this represents substantial supply and remains one of the principal bearish arguments facing the coffee market.

However, gross production and commercially usable production should not necessarily be treated as equivalent. The 2026 harvest has been affected by difficult weather during its final stages, including repeated rainfall that complicated harvesting and drying. An unusually large quantity of arabica appears to have reached the ground before collection, creating significantly greater exposure to moisture, fermentation and deterioration.

Market indications suggest that the proportion of ground-collected coffee is considerably above normal this season. In some producing areas, the quality deterioration has been severe enough to create an exceptional price separation between good-quality coffee and heavily damaged material. In Minas Gerais, good-quality coffee has recently been valued around R$1,700–1,720 per 60-kg bag, while heavily damaged ground-collected lots have reportedly attracted bids of only R$500–600 per bag.

That difference has important economic consequences. When the value of damaged coffee falls sufficiently far below standard grades, the cost of collecting, drying, processing and transporting the remaining beans may no longer justify the operation. A quality problem can therefore eventually become a volume problem because some coffee becomes economically unattractive to recover. There are also reports of mold, fermentation and strong off-odours in portions of the lower-quality crop, which can limit blending flexibility and sharply reduce the commercial value of affected beans.

Could Brazil ultimately have only 60–62 million commercially recoverable bags?

Market estimates increasingly suggest that Brazil's effective 2026 supply could eventually prove closer to 60–62 million bags than the official 67.6-million-bag production estimate. That possibility can be tested mathematically by applying losses only to the arabica component of the crop.

This calculation is a scenario rather than a crop forecast. It would only be valid if the losses were additional to those already incorporated into the official estimate, and if the affected coffee genuinely became unavailable rather than simply being sold at lower grades. Nevertheless, it demonstrates why estimates around 60–62 million bags have emerged. They are mathematically plausible if arabica recoverability proves substantially worse than currently reflected in the official number.

The market therefore needs to distinguish carefully between Brazilian production, economically recoverable coffee and coffee meeting normal export and exchange-quality specifications. Those quantities can differ materially, and the gap between them may prove more important for price formation than the headline crop figure itself.

ICE arabica stocks remain critically low

Certified arabica inventories remain one of the strongest counterweights to the large Brazilian crop narrative. ICE certified stocks are currently close to 254,000 bags, having declined by approximately 4,100 bags during the latest week. A year earlier, certified stocks were close to 580,000 bags, representing a decline of roughly 56% year on year.

The absolute size of the inventory is particularly important. At approximately 254,000 bags, exchange stocks represent only a small fraction of annual global arabica consumption and leave the market more sensitive to disruptions in the replenishment process. However, stocks should not be analysed in isolation, because more Brazilian coffee is moving toward exchange warehouses and large volumes have reportedly been prepared for potential certification.

Estimates around 300,000 bags have circulated regarding coffee intended for delivery and grading. If a substantial proportion of that coffee passes inspection, ICE inventories could recover materially. If certification continues to encounter quality problems, the outcome could be very different. The scale of potential inflows is therefore large enough to alter the inventory picture, but only successful certification will determine whether those beans actually become part of the deliverable stock pool.

Certification may become one of the market’s most important indicators

Approximately 21,000 bags were recently awaiting certification, while rejection levels for some Brazilian submissions have reportedly been unusually high. A sizeable Honduran parcel of approximately 13,700 bags was also recently rejected. Individual rejection events should not be extrapolated across all incoming coffee, but they deserve attention because they test one of the major bearish assumptions currently embedded in the market: that Brazil's large harvest will rapidly rebuild depleted exchange inventories.

Coffee physically present in an ICE warehouse is not necessarily certified coffee. Beans must satisfy exchange specifications before entering the deliverable stock pool. The next several weeks therefore provide a useful real-world test of Brazil's crop quality. If large quantities enter warehouses but relatively little coffee successfully becomes certified, the market will have stronger evidence that the quality problem is affecting deliverable supply.

Brazil's exports remain substantial

Any bullish interpretation of Brazilian quality problems must also account for the fact that coffee continues to leave the country in significant quantities. By September 25, Brazilian coffee shipments had reached approximately 2.81 million bags, consisting of roughly 2.02 million bags of arabica, 577,000 bags of conilon and 213,000 bags of soluble coffee. Shipments were approximately 4.5% below the comparable point in August.

At the same time, requests for certificates of origin were running well ahead of actual shipments, pointing to a substantial export pipeline. September exports could consequently remain strong into month-end. This matters because strong exports demonstrate that the quality problems are not preventing Brazil from supplying the international market.

However, export strength does not invalidate the quality issue. A country can simultaneously export large quantities of coffee while experiencing shortages or substantial premiums in particular grades. Buyers may source acceptable coffee from specific regions, existing inventories or higher-quality portions of the crop while poorer-quality beans accumulate elsewhere. The issue therefore remains one of composition rather than simply total volume.

Brazilian producers remain reluctant sellers

The domestic physical market also provides useful information. Buyer interest remains significant across several coffee grades, but trading volumes have remained relatively restrained. Producers appear to be selling primarily to meet immediate financial commitments rather than aggressively marketing the crop.

Currency movements have helped maintain local values despite the decline in New York. The Brazilian real weakened during the week from approximately R$5.145 to R$5.182 per US dollar. As a result, the local-currency equivalent of December futures remained close to R$1,910 per bag, despite the decline in the ICE contract.

Funds substantially reduced bullish exposure

Speculative positioning also changed materially during the latest reporting period. Large speculative traders substantially reduced their net-long exposure as arabica prices declined. The adjustment came through a combination of long liquidation and increased short exposure, indicating that bearish participation grew during the decline rather than the move being driven purely by existing longs exiting the market.

At the same time, commercial participants substantially reduced their net-short exposure. This produces an interesting setup because speculative positioning is now considerably less bullish than it was several weeks ago, while fresh short exposure has entered the market after a major correction.

That does not create a bullish signal by itself, but it changes the asymmetric risk around price movements. If fundamental conditions deteriorate further, shorts can remain comfortable. If prices begin recovering through important resistance levels, however, recently established shorts can become an additional source of buying. Friday's rebound may already contain some element of this dynamic, although positioning data cannot determine the exact composition of Friday's trading flows.

The spread structure does not yet confirm outright scarcity

Coffee's calendar spreads are sending a more nuanced signal than outright prices. The New York December/March premium narrowed slightly during Friday's recovery, to approximately 7.4 cents/lb. If the rally had been driven primarily by an immediate shortage of nearby arabica supply, a stronger nearby premium might normally be expected. Instead, the outright contract recovered while the nearby spread softened modestly.

London moved in the opposite direction, with November's premium over January widening to $25/t. The two markets are therefore not producing a uniform physical-tightness signal. This reinforces the argument that Friday's movement should initially be considered a technical recovery within a market that remains fundamentally contested, rather than evidence that the supply outlook has suddenly become bullish.

The next crop is becoming the second major risk

The market is simultaneously beginning to focus on Brazil's next production cycle. Recent rainfall has supported flowering across important growing regions, which is constructive, but flowering is only the first stage of the process. Successful production requires sufficient moisture and manageable temperatures during flower setting and early fruit development.

The emerging El Niño environment therefore deserves monitoring. The risk is not that El Niño automatically means a poor Brazilian coffee crop, because the relationship is considerably more complex and regional rainfall outcomes can vary significantly. The relevant concern is whether Brazil experiences prolonged periods of excessive heat combined with insufficient rainfall after flowering.

If flowers are lost before successful fruit setting, the production potential for the next crop can decline rapidly. For now, this remains a weather risk rather than confirmed crop damage. That distinction is essential, particularly because the market has already experienced one harvest affected by difficult weather and quality deterioration. If the next production cycle were also to encounter meaningful problems, today's relatively comfortable headline supply estimates could become substantially less reassuring.

Technical picture: recovery underway, confirmation still required

December arabica finished Friday at 278.60 cents, leaving the market around the critical 275–280-cent area. The immediate resistance zone lies around 283.85–284.30 cents, effectively Friday's upper trading area. A sustained break above this zone would expose approximately 289.10 cents, followed by the 293–294-cent region.

On the downside, the first meaningful support remains around 273.80 cents, followed by approximately 269.00 cents. The 269–270-cent region is particularly important because buyers emerged aggressively after the market tested this area earlier in the week. A renewed sustained break below it would materially weaken the recovery structure and reopen the lower 260-cent region.

For robusta, November's close at $3,367/t restores the market above the $3,300 threshold. The immediate test is whether prices can hold above this area and subsequently challenge Friday's $3,375 high. Neither market has yet produced sufficient evidence to classify the recent movement as a confirmed medium-term reversal.
