A rain-delayed harvest in Brazil, a stronger local currency and tightening exchange inventories have combined to send arabica futures up by 16.2% in a single session this month, even as multiple forecasters project the largest coffee surpluses in years.
On 6 July 2026, September arabica on ICE jumped 48.75 cents to close at 349.95 US cents per pound – the largest one-day rise this century – while robusta futures rose 8.8% to US$4044, according to Global Coffee Report reporter Daniel Woods. Woods linked the rally to delays in Brazil’s 2026/27 harvest, strength in the Brazilian real and producers holding back sales.
Those price spikes landed just as Brazilian fieldwork fell notably behind schedule. Analyst Gil Barabach of Safras & Mercado told HCNTimes that Brazil’s 2026/27 coffee harvest was 52% complete as of 1 July, compared with 60% at the same point a year earlier and a five-year average of 55%. By 15 July, Safras & Mercado estimated 64% of the crop had been picked, still well below 77% a year ago and a 70% five-year average.
Heavy rains in key producing regions have slowed machinery and damaged quality. In Minas Gerais, Brazil’s largest arabica state, only 30% of the crop had been harvested by early July versus a historical average of 40%, according to state agency Emater-MG as cited by Valor International. On the same date, cooperative Cooxupé reported its members’ harvest at 24.9% complete, down from 31.4% at the end of June 2025, Valor added.
Producers quoted by Valor described unusually severe on-farm losses. Monte Carmelo grower Hemerson Bovi said, “Mechanical harvesting typically causes losses of 15% to 25% of production—but this year, because of the rain, losses have reached 50%.” A Cerrado Mineiro producer told the newspaper that “a lot of coffee has fallen to the ground, and some beans are already sprouting,” predicting “very little premium coffee for export and a lot of medium-quality coffee.”
Quality concerns are also surfacing in southern Minas Gerais. Sérgio Meirelles Filho, president of the regional association Sindicafé-MG, told Valor that early deliveries this season were already grading as hard riado, describing “fermented from the rain” lots and “alarming” beverage quality at the very start of the harvest.
Despite the accelerated picking pace in mid-July, Barabach cautioned that the faster rhythm had not yet translated into more physical coffee reaching the market. Speaking to CNN Brasil on 4 July, he said the time needed for drying and processing meant the additional harvested volume was not immediately available for shipment.
The tightening nearby supply coincides with declining certified stocks on ICE. HCNTimes reported that exchange arabica inventories fell to a 2.25-year low of 334,254 bags on 16 July 2026. For robusta, ICE stocks hit a two-year low of 3,631 lots on 15 May before rebounding to a 3.5-month high of 4,220 lots by 14 July, the same outlet noted.
Currency moves have amplified the impact of Brazil’s slower harvest on New York and London prices. In a series of reports for Barchart, analyst Rich Asplund recorded arabica and robusta futures rising on 27 January, 8 April, 23 April and 5 May as the real climbed to successively stronger multi-year highs, discouraging export selling. When the real weakened to a one-week low on 27 May, Asplund reported that both contracts fell as long positions were liquidated.
By mid-July, the real was about 8% stronger against the US dollar year-on-year, trading near 5.09 to the dollar on 16 July, supported by Brazil’s 14.25% Selic benchmark interest rate, according to EBC Financial Group. EBC also noted that new US tariffs taking effect from 22 July will add 25% to many Brazilian exports, though coffee is exempt from the measure.
These harvest and currency pressures arrive against a backdrop of forecasts calling for ample supply. Brazil’s official agency Conab projected a record 2026 crop of 66.2 million bags on 5 February, while subsequent private and government estimates for the 2026/27 Brazilian harvest range from 71.4 million bags (Coffee Trading Academy) to 75.9 million (Marex Group Plc), with Sucafina and StoneX clustered just below that figure and USDA’s Foreign Agricultural Service at 71.9 million bags.
Global balance sheets also look comfortable on paper. StoneX has estimated a [UNVERIFIED] 10-million-bag global coffee surplus in 2026, the biggest in six years, and Rabobank has raised its [UNVERIFIED] 2026/27 arabica surplus forecast to 9.5 million bags, according to Barchart and HCNTimes coverage of those outlooks.
At the same time, Vietnam is shipping more coffee into the robusta market: the country’s statistics office reported 2025 exports up 17.5% to 1.58 million metric tonnes and 2026 shipments reaching 1.05 million tonnes in the January–June period, a 7.3% year-on-year increase, as cited by Barchart and HCNTimes.
Yet even with these larger crops and surplus projections, HCNTimes reported that speculative funds increased their net-long positions in ICE robusta to 44,195 lots in the week to 7 July, the highest level in more than two years, underscoring how Brazil’s delayed, weather-hit harvest and a firmer real have been enough to keep coffee prices highly volatile in the middle of a seemingly well-supplied cycle.
