Global Coffee Supply Dynamics Drive Recent Price Movement

Coffee futures experienced significant momentum this week, with March arabica coffee (KCH26) gaining +1.48% and January robusta coffee (RMF26) advancing +1.06%. The rally reflects a complex interplay of supply constraints and weather-related concerns reshaping the near-term outlook for these commodities.

Supply Disruptions Support Coffee Quotes Across Both Varieties

Multiple production challenges are currently underpinning coffee prices in the market. Indonesia, the world’s third-largest robusta producer, faces unprecedented flooding that threatens to slash exports by up to 15% during the 2025-26 season. The disaster has impacted approximately one-third of the country’s arabica coffee farming regions in northern Sumatra, with industry officials expressing concern about export availability.

Brazil’s weather patterns also contributed to bullish sentiment. Minas Gerais, Brazil’s primary arabica-growing zone, received 38.3 mm of rain during the week ending December 19—representing 76% of its historical average. This rainfall situation created buying interest ahead of forecasted heat waves expected to extend through early next week.

Inventory Tightness Reinforces Price Support

Another factor supporting coffee quotes has been the contraction in available supplies monitored by ICE. Arabica coffee inventories recently touched a 1.75-year low of 398,645 bags in mid-November, though they subsequently recovered to 456,477 bags. Robusta stocks similarly hit an 11.5-month low of 4,012 lots before rebounding to 4,278 lots.

US market dynamics have also influenced purchasing patterns. American buyers significantly reduced Brazilian coffee purchases when tariffs were in effect—August through October purchases dropped 52% year-over-year to 983,970 bags. Despite subsequent tariff reductions, US coffee inventories remain constrained.

Production Forecasts Present Mixed Signals

Looking ahead, the supply picture becomes more nuanced. Brazil’s crop forecasting agency (Conab) revised its 2025 production estimate upward by 2.4% to 56.54 million bags. However, the USDA’s Foreign Agriculture Service projects Brazil’s output declining 3.1% year-over-year to 63 million bags for 2025/26, while arabica production faces a 4.7% decline globally.

Vietnam, the world’s largest robusta producer, presents a different trajectory. The country’s November coffee exports surged 39% year-over-year to 88,000 MT, with January through November cumulative exports rising 14.8% to 1.398 million metric tons. Vietnam’s 2025/26 production is projected to climb 6% year-over-year to 1.76 million metric tons—a four-year high.

Global Market Perspective

The International Coffee Organization reported that global coffee exports for the October-September marketing year fell 0.3% year-over-year to 138.658 million bags, indicating modest export pressure despite abundant production capacity. The USDA’s latest forecast suggests world coffee production will increase 2.0% year-over-year to a record 178.848 million bags in 2025/26, with robusta production climbing 10.9% while arabica faces headwinds.

Global ending stocks are expected to decline 5.4% to 20.148 million bags from 21.307 million bags in the previous year, suggesting tightening availability as demand remains resilient.

The current coffee market reflects the tension between expanding global production capacity and near-term supply constraints—a dynamic that will likely continue shaping price behavior for coffee quotes throughout the coming months.
