Global Coffee Market Faces Tug-of-War: Indonesian Disaster Meets Record Supply Surge

Coffee prices are sending mixed signals as the market wrestles with conflicting forces. March arabica futures dropped -1.90 points (-0.55%), while January robusta contracts gained +42 points (+1.06%), reflecting the divided sentiment gripping traders.

Natural Disaster Provides Price Support

Indonesia’s severe flooding is emerging as a crucial bullish factor for coffee markets. The catastrophic weather has devastated approximately one-third of the country’s arabica coffee farms in northern Sumatra, threatening to slash Indonesia’s coffee exports by as much as 15% during the 2025-26 season, according to officials from the Association of Indonesian Coffee Exporters and Industry. Since Indonesia ranks as the world’s third-largest robusta producer, any supply disruption carries significant weight for global markets.

Brazil’s arabica heartland, Minas Gerais, offers some relief with recent moisture levels at 76% of historical norms, suggesting adequate growing conditions ahead.

Inventory Drawdowns Signal Tightening Supply

Physical stockpiles are shrinking across major exchanges. ICE-monitored arabica inventories hit a 1.75-year low of 398,645 bags on November 20 before recovering modestly to 456,477 bags by midweek. Robusta inventories similarly dipped to an 11.5-month low of 4,012 lots before bouncing to 4,278 lots by week’s end. These tighter inventory levels are supporting prices amid concerns about sustained demand.

Domestically, US coffee supplies remain constrained. American importers slashed Brazilian coffee purchases by 52% from August through October—when Trump’s tariffs discouraged buying—acquiring just 983,970 bags compared to the prior year’s period. Despite tariff reductions since, inventory replenishment remains gradual.

Abundant Production Weighs on Market

The bearish case for prices centers on explosive supply growth. Vietnam, the world’s dominant robusta producer, boosted November exports by 39% year-over-year to 88,000 MT, with cumulative Jan-November shipments up 14.8% to 1.398 MMT. Vietnam’s 2025/26 coffee production is projected to climb 6% to 1.76 MMT (29.4 million bags), marking a 4-year peak, with the Vietnam Coffee and Cocoa Association suggesting output could be 10% higher if weather cooperates.

Brazil’s coffee production forecast underwent significant revision upward. Conab raised its 2025 estimate by 2.4% to 56.54 million bags in December, adding 1.34 million bags to September’s projection. However, FAS projects Brazil’s 2025/26 output will actually decline 3.1% to 63 million bags, creating conflicting expectations for major suppliers.

Global Production Sets New Records

The International Coffee Organization reported global exports for the current marketing year fell marginally by 0.3% to 138.658 million bags, a surprisingly resilient figure given production growth. The USDA’s Foreign Agriculture Service forecasted world coffee production will expand 2.0% to a record 178.848 million bags in 2025/26, driven by a substantial +10.9% jump in robusta to 83.333 million bags. Arabica production, however, faces headwinds with a projected -4.7% decline to 95.515 million bags.

Looking ahead, ending global coffee stocks are expected to compress 5.4% to 20.148 million bags for 2025/26, down from 21.307 million bags the prior year—a notable tightening that could support price floors.

Market Takeaway

Coffee prices are caught between Indonesia’s supply disruption and Vietnam’s robust production surge. While shrinking inventories and record-high global production paint a complex picture, the short-term support from weather-related supply threats may limit downside risk for prices in the near term, even as long-term abundance looms.
