Vietnamese Coffee Surge Amid Weather Pressures and Global Supply Tightening

Robusta coffee futures are experiencing notable strength today, climbing to 2-week highs as weather disruptions reshape the global coffee market landscape. March arabica coffee (KCH26) gained +2.15 (+0.57%), while January ICE robusta futures (RMF26) surged +107 (+2.37%), signaling renewed investor interest in coffee commodities.

Climate Events Driving Price Movement

Vietnam’s coffee harvest faces significant headwinds from heavy rainfall in Dak Lak province, the nation’s leading coffee-growing region. Forecasted additional precipitation threatens crop quality and delays harvesting activities, providing upside support to robusta prices. Vietnam, as the world’s dominant robusta coffee producer, carries outsized influence on global robusta supply dynamics.

Meanwhile, Brazil’s coffee-growing regions are anticipated to receive substantial rainfall toward the end of the week and into next week, according to Climatempo forecasts. While adequate moisture supports crop development, the precipitation arrived amid ongoing concerns about Brazilian crop viability. Minas Gerais, Brazil’s largest arabica-growing area, received only 19.8 mm of rain during the week ended November 14—representing just 42% of historical averages—raising questions about longer-term moisture sufficiency.

Supply Dynamics Reshaping Market Expectations

Global coffee inventories are tightening meaningfully, creating structural support for prices. ICE arabica inventories hit a 1.75-year low of 396,513 bags on Tuesday, while ICE robusta coffee stocks fell to a 4-month low of 5,640 lots. This inventory compression reflects reduced US purchases of Brazilian coffee, which dropped 52% year-over-year during August-October 2025.

Production forecasts, however, present a mixed picture. Brazil’s 2025/26 arabica crop is projected to reach 47.2 million bags—a 29% year-over-year increase according to StoneX forecasts, while total Brazilian production could reach 70.7 million bags for the 2026/27 marketing year. Simultaneously, vietnamese coffee output is climbing, with Vietnam’s 2025/26 production anticipated at 1.76 million metric tons, representing a 6% year-over-year increase and hitting a 4-year high. Vietnam’s coffee exports for January-October 2025 rose 13.4% year-over-year to 1.31 million metric tons.

The International Coffee Organization reported that global coffee exports for the current marketing year (October-September) declined 0.3% year-over-year to 138.658 million bags, indicating tighter global availabilities despite production gains.

Trade Policy Uncertainty Constraining US Supplies

US tariff policies continue influencing coffee market structure. The Trump administration’s 40% tariff on Brazilian coffee imports has redirected trade flows and constrained US supplies, since approximately one-third of American unroasted coffee originates from Brazil. American buyers have reduced new Brazilian coffee contract commitments due to tariff exposure, creating supply tightness in the US market despite global production increases.

Near-term price momentum reflects these competing forces: supply tightening from reduced US imports, inventory drawdowns, and weather disruptions in major producing regions are offsetting the bearish implications of rising global production forecasts.
