Dollar Strength Reverses Coffee Rally as Supply Concerns Emerge

The coffee futures market experienced a mixed performance on Tuesday, with divergent price movements across different bean varieties. Arabica coffee for March delivery declined by 1.95 points, closing down 0.55%, while robusta coffee gained 62 points to settle up 1.57%. Despite climbing to 2-week highs earlier in the session, arabica coffee retreated as dollar strength reasserted pressure on commodity futures.

Dollar Index Triggers Liquidation Wave

Tuesday's surge in the dollar index to a 1-week high sparked significant selling pressure in coffee futures contracts. The stronger greenback typically encourages investors to liquidate long positions in dollar-denominated commodities, which explains the intraday reversal from earlier gains. This technical dynamic underscores how macroeconomic factors can override fundamental supply-demand considerations in short-term price action.

Production and Export Headwinds Persist

Brazil's Crop Moisture Concerns

Support for arabica coffee prices carries forward from Monday's developments regarding Brazil's coffee production outlook. Somar Meteorologia reported that Minas Gerais, responsible for the majority of Brazil's arabica production, received only 11.1 mm of rainfall during the week ending December 26. This represents just 17% of the historical average, raising concerns about adequate moisture for crop development. Compounding these worries, Brazil's 2025 total coffee production estimate was raised by 2.4% to 56.54 million bags in December, according to Conab's latest forecast. However, USDA projections paint a more cautious picture, forecasting a 3.1% decline in Brazil's 2025/26 output to 63 million bags.

Indonesia's Flooding Impact

Extensive flooding across Indonesia threatens to substantially reduce coffee export volumes. The Association of Indonesian Coffee Exporters and Industry chairman warned that the country's coffee exports could contract by up to 15% during the 2025-26 season. The flooding has devastated approximately one-third of Indonesia's arabica coffee farms in northern Sumatra, though robusta crops have experienced relatively less damage. As the world's third-largest robusta producer, any disruption to Indonesia's supply chain carries meaningful implications for global coffee availability.

Vietnam's Production Surge

Vietnam's coffee sector continues to expand aggressively. The National Statistics Office reported that November coffee exports surged 39% year-over-year to 88,000 MT, with January-November cumulative exports climbing 14.8% year-over-year to 1.398 MMT. Looking ahead, Vietnam's 2025/26 coffee production is projected to increase 6% year-over-year to 1.76 MMT (29.4 million bags), marking a 4-year high. The Vietnam Coffee and Cocoa Association indicated that 2025/26 output could climb 10% above the prior crop year if weather proves favorable. As the world's largest robusta producer, Vietnam's rising supply weighs on robusta price prospects despite other supportive factors.

Inventory Dynamics Remain Mixed

ICE arabica coffee inventories have fluctuated around concerning levels. Stocks hit a 1.75-year low of 398,645 bags on November 20 but subsequently recovered to 456,477 bags, a 2-month high, last Wednesday. For robusta, inventories fell to a 1-year low of 4,012 lots on December 10 before bouncing to 4,278 lots, a 4-week high, by Tuesday and Wednesday. While the early-month lows signal constrained supplies, the recent recovery suggests that inventory pressures may be moderating.

Tariff Effects and US Demand Recalibration

American coffee purchases from Brazil contracted sharply during the tariff period. From August through October, when President Trump's tariffs were in effect, US imports of Brazilian coffee dropped 52% year-over-year to 983,970 bags. Although tariffs have since been reduced, US coffee inventories remain constrained, suggesting limited near-term demand recovery despite improved trade conditions. This dynamic reflects the lagged impact of trade policy on purchasing patterns and supply chain reorganization.

Global Supply Trajectory and Long-Term Outlook

The International Coffee Organization reported that global coffee exports for the current marketing year (October-September) fell 0.3% year-over-year to 138.658 million bags, indicating surprisingly modest export momentum despite expectations for ample supplies.

The USDA Foreign Agriculture Service's December 18 report projects more substantial supply growth ahead. World coffee production in 2025/26 is forecast to increase 2.0% year-over-year to a record 178.848 million bags. However, arabica production faces headwinds, projected to decline 4.7% to 95.515 million bags, while robusta production is expected to surge 10.9% to 83.333 million bags. Global ending stocks are anticipated to contract 5.4% to 20.148 million bags from 21.307 million bags in 2024/25, suggesting some tightening in the balance sheet despite record overall production.

The coffee market continues to navigate competing forces: weather-related supply concerns in key growing regions provide support, while expanding production in Vietnam and growing global inventories from prior seasons create offsetting pressure. The Tuesday session's reversal underscores how external factors, particularly currency movements, can override fundamental considerations in determining near-term price direction.
