Coffee Prices Plunge on Rain Forecasts for Brazil
Dubai, September 18, 2025 – (Qahwa World) – Global coffee markets faced a sharp downturn on Wednesday as prices tumbled amid forecasts of long-awaited rainfall in Brazil, the world’s largest coffee producer. December arabica futures (KCZ25) closed down -33.70 cents, a steep -8.23%, marking a one-week low. November ICE robusta futures (RMX25) also plunged by -331 points, or -6.92%.
The sudden reversal came just a day after arabica reached a contract high and robusta hit a three-week peak, driven by drought conditions. Forecasts now indicate showers in Brazil’s key coffee-growing regions beginning next week, triggering heavy long liquidation in the market.
Brazil’s Cooxupe cooperative, the largest in the country, announced that the harvest among its members was 98.9% complete as of September 12, adding further bearish pressure. The completion of the harvest, coupled with improved weather outlooks, weighed heavily on investor sentiment.
Yet underlying fundamentals remain tense. Earlier this month, Brazil’s crop forecasting agency Conab revised its 2025 arabica production estimate down by -4.9% to 35.2 million bags, while total coffee output was trimmed to 55.2 million bags. Global supply challenges also persist: the International Coffee Organization (ICO) reported that July exports fell -1.6% year-on-year, while cumulative exports from October to July slipped -0.3%.
On the demand side, U.S. buyers continue to face supply strain due to 50% tariffs on Brazilian coffee, effectively tightening the American market, where one-third of unroasted coffee imports come from Brazil. Meanwhile, ICE-monitored inventories continue to dwindle, with arabica stocks dropping to a 16.5-month low of 659,949 bags and robusta inventories falling to a 1.5-month low of 6,551 lots.
Vietnam, the world’s second-largest coffee producer, is also under scrutiny. Severe drought reduced the 2023/24 crop by -20% year-on-year to 1.472 million metric tons, the smallest harvest in four years. Exports in 2024 declined -17.1%, though shipments from January to August 2025 were up +7.8% year-on-year, showing signs of recovery.
Looking ahead, the USDA’s Foreign Agriculture Service projects global coffee production in 2025/26 will reach a record 178.68 million bags, up +2.5% year-on-year, supported by strong robusta output. However, research firm Volcafe warns that arabica will face a deficit of -8.5 million bags in 2025/26, the fifth consecutive year of shortage.
For now, rain forecasts in Brazil have calmed fears of immediate supply disruption, but the broader picture of tightening inventories, tariffs, and shifting climate risks ensures that volatility will remain a defining feature of the global coffee market.
