Dubai – Qahwa World
The global coffee market witnessed a significant price surge in September 2025, marking one of the strongest monthly performances in recent years. According to the latest Coffee Market Report issued by the International Coffee Organization (ICO), the ICO Composite Indicator Price (I-CIP) averaged 324.62 US cents per pound, representing a 9.3% increase compared to August 2025 and a striking 25.4% rise year-on-year. The report reveals that while prices rose across all coffee groups, tightening certified stocks and persistent trade uncertainties continue to define the market’s volatile landscape.
The ICO noted that Arabica varieties led the monthly increase, with Colombian Milds climbing 10.1% to 403.77 US cents/lb, Other Milds advancing 9.3% to 400.21 US cents/lb, and Brazilian Naturals gaining 11.3% to 374.91 US cents/lb. Robusta, meanwhile, registered a more moderate yet notable 5.9% increase to 210.85 US cents/lb. The rise was mirrored on both major futures exchanges, with New York ICE prices up 11.5% to 366.31 US cents/lb, and London ICE prices increasing by 8.9% to 197.56 US cents/lb. The I-CIP fluctuated between 298.14 and 360.74 US cents/lb during the month, maintaining a median value of 323.44.
The report attributes much of September’s price escalation to several interconnected macroeconomic and policy-related developments that placed upward pressure on the market during the first half of the month. Among these, concerns over the long-term supply of coffee to the United States stood out, especially given the continued uncertainty surrounding import tariffs. Although on 8 September the U.S. administration issued an executive order revising tariffs for “aligned partners” with established trade agreements, coffee remained excluded from the list. The commodity continues to face a 50% import tariff imposed earlier in the year, as it is not yet categorized among products that the U.S. cannot sufficiently produce domestically. This policy has led to sustained apprehension among traders and exporters, particularly as U.S. certified Arabica stocks continue to decline.
The ICO underlined that certified stocks—used as a short-term substitute for coffee imports—are shrinking at an alarming rate, reinforcing market tightness. U.S. certified stocks of Arabica fell 19.3% in September to 0.66 million 60-kilogram bags, while London-certified Robusta stocks decreased 4.3% to 1.08 million bags. These drawdowns, the report states, indicate that the market is “starting to feel the squeeze,” signaling a bullish outlook for prices if replenishment remains weak.
However, the latter half of September brought developments that introduced downward pressure and tempered speculative enthusiasm. On 15 and 17 September, the ICE Futures U.S. exchange raised margin requirements for Arabica contracts twice in a single week. Higher margin requirements force investors to deposit more capital with brokers to cover increased credit risk, thus raising borrowing costs for both new and existing positions. The ICO explained that such moves can reduce liquidity and limit speculative demand, potentially stabilizing prices in overheated markets.
At the same time, discussions at the United Nations General Assembly between U.S. and Brazilian officials provided a momentary boost to market optimism. As the world’s largest coffee producer and the largest destination market sought to improve bilateral trade relations, investors interpreted the talks as a signal that tariff détente might eventually follow. Brazil’s exports have been under severe strain, declining for ten consecutive months due to both cyclical production factors and logistical issues at the port of Santos.
On the monetary front, the U.S. Federal Reserve’s 25-basis-point interest rate cut on 17 September had a nuanced impact. While the policy was intended to lower borrowing costs across the economy, it indirectly affected coffee prices by making speculative trading less expensive. The ICO noted that cheaper credit may have helped sustain trading volumes, adding volatility to a market already under pressure from tightening supplies.
The European Union also entered the spotlight in September after the EU Commissioner for Environment, Water Resilience and a Competitive Circular Economy raised concerns over the readiness of the EU Deforestation Regulation (EUDR) IT system. The Commissioner indicated that the system might not be able to handle the expected transaction volume, suggesting a possible one-year extension before enforcement begins. The EUDR, which aims to ensure that coffee and other commodities imported into the EU are deforestation-free, has been a major topic of concern among exporters since its adoption, and any delay could temporarily ease compliance-related pressures on coffee-producing nations.
Despite these counterbalancing developments, overall volatility continued to rise. The ICO reported that intra-day volatility of the I-CIP increased by 2.8 percentage points compared to August, averaging 13.8% in September. By category, Colombian Milds and Other Milds showed volatility of 14.0% and 13.7%, respectively, Brazilian Naturals 14.7%, and Robustas 15.0%. At the futures level, New York volatility stood at 15.2%, while London measured 16.2%, reflecting a minor uptick in speculative activity.
Price differentials also widened notably. The Colombian Milds–Other Milds differential expanded from 0.41 to 3.56 US cents/lb, while the Colombian Milds–Robustas differential rose 15.1% to 192.92 US cents/lb. The arbitrage between the London and New York markets, a key indicator of the spread between Arabica and Robusta, widened by 14.7% to 168.75 US cents/lb, the highest level of the year.
Overall, the ICO described September as a month defined by tightening supplies, speculative activity, and geopolitical uncertainty. The consistent decline in certified stocks, combined with unresolved tariff tensions and potential EUDR delays, continues to reinforce a bullish sentiment across the market. As the fourth quarter of 2025 begins, analysts expect coffee prices to remain elevated, with volatility likely to persist until structural issues—such as logistics bottlenecks, regulatory clarity, and weather-related production concerns—are addressed.
In summary, the ICO’s latest data depict a coffee market under strain but also opportunity. Prices are buoyed by constrained supply and investor sentiment, while trade policies and financial dynamics continue to influence short-term movements. With the I-CIP climbing above 320 US cents/lb for the first time in over two years and certified stocks hitting new lows, September 2025 may well be remembered as a turning point in the evolving balance between global coffee supply and demand.
