Coffee Prices Rally on Weather Concerns

Coffee prices surged, driven by immediate concerns over below-normal rainfall in Brazil's arabica regions and a typhoon threat to Vietnam's robusta crop, which are further depleting ICE inventories to multi-year lows. This bullish sentiment is tempered by speculation of a potential lifting of US tariffs on Brazilian coffee and projections for increased Vietnamese robusta output, expected to reach a four-year high in 2025/26. While a La Niña forecast indicates future dry conditions for Brazil's 2026/27 crop, USDA projections still anticipate record global coffee production in 2025/26, presenting a mixed market outlook.

Analysis

Coffee prices rallied significantly, with December arabica up +3.72% and January robusta up +3.37%, driven by immediate supply concerns. Below-normal rainfall in Brazil's Minas Gerais, receiving only 75% of its historical average, and a typhoon threat (Kalmaegi) to Vietnam's robusta regions are key factors. These events are exacerbating already tight ICE inventories, with arabica stocks at a 1.75-year low and robusta at a 3.5-month low.

The current inventory tightness is partly attributed to 50% US tariffs on Brazilian coffee, which have deterred American buyers and tightened US supplies. However, speculation about a potential tariff lift, following recent positive US-Brazil trade talks, could temper arabica price support. Conversely, robusta prices face pressure from projected increased Vietnamese supplies, with 2025/26 production forecast to rise +6% year-over-year to a four-year high.

Looking ahead, a 71% chance of a La Niña system could bring dry weather to Brazil, potentially impacting the 2026/27 arabica crop. Despite this, USDA forecasts indicate record global coffee production in 2025/26, up +2.5% year-over-year, primarily from a +7.9% increase in robusta output. This presents a complex market with short-term weather-driven bullishness offset by longer-term supply growth expectations.

Key Decisions for Investors

• Investors should closely monitor weather patterns in Brazil and Vietnam, as these immediate supply risks are key drivers of current coffee price volatility.
• Evaluate the progress of US-Brazil trade talks regarding the 50% coffee tariff, as its potential removal could significantly impact arabica supply dynamics and price support.
• Consider potential hedging strategies given the mixed outlook, balancing short-term weather-induced bullishness with USDA's forecast for record global production in 2025/26, particularly for robusta.
