Coffee Rally Meets Brazilian Harvest Wall as El Niño Risk Builds

Global coffee prices are set to remain structurally supported into 2027 despite a strong Brazilian 2026/27 harvest, as thin inventories, a strengthening El Niño and expectations of a smaller Brazil crop in 2027/28 keep upside risks elevated. Short-term corrections are likely as Brazilian beans hit the market, but the medium-term balance is tightening again. After a sharp rebound since June, the coffee market is transitioning into a two‑phase environment. In late 2026 and early 2027, abundant Brazilian supplies and a nearly completed 2026/27 harvest could briefly cap prices. Further out, attention is already shifting to the down‑cycle of Brazil’s arabica biennial pattern, renewed weather risks for Asian robusta under a strengthening El Niño, and higher input costs in key origins. Together with historically low inventories, this mix argues for continued price volatility with a firm underlying floor rather than a sustained bear market.

Prices

BMI has raised its 2026 average coffee price forecast to 307 cents/lb (around EUR 6.30/kg) from 293 cents, after prices rebounded from 240.9 cents/lb on 9 June to 332 cents/lb on 18 August and have averaged about 316 cents/lb so far this quarter. This rally is stronger than previously expected but still aligned with the structural backdrop of thin inventories and elevated supply risk.

Physical differentials in Vietnam underscore this firmness. Recent FOB offers from Hanoi show robusta green wet‑polished beans around EUR 4.40/kg (scr18) and EUR 4.10/kg (scr16), while unwashed robusta trades near EUR 3.90–4.05/kg depending on screen size. Vietnamese arabica grade 1 and 2 stand around EUR 7.80/kg and EUR 6.75/kg respectively, broadly stable over the past three weeks, indicating that futures volatility has not yet translated into sharp moves in Vietnamese cash quotes.

Supply & Demand

Near‑term supply is dominated by Brazil’s large 2026/27 crop. BMI projects global coffee production at 188.9 million bags in 2026/27, up 6% year on year, with Brazilian output rising 14.1% to 71.9 million bags and Vietnam up modestly by 0.6% to 31.9 million bags. Harvest reports from Brazil indicate that around 97% of the 2026/27 crop had been collected by late August, confirming substantial physical availability into Q4 2026.

This production surge widens the 2026/27 global surplus to a still‑comfortable 14.4 million bags. However, BMI expects the surplus to narrow sharply to 9.2 million bags in 2027/28 – a 36% reduction, cutting the market’s buffer against weather shocks. With global inventories already described as historically thin, this means that any production disappointment in Brazil or Asia would transmit disproportionately to prices.

Fundamentals & Weather

The supportive medium‑term story rests on a weaker Brazilian crop and heightened weather risk. Brazil’s arabica output will move into the lower phase of its biennial cycle in 2027/28, with BMI forecasting total Brazilian production to fall 5.1% year on year to 68 million bags. That decline would unwind part of the current surplus and re‑tighten the world balance just as demand continues to grow steadily.

El Niño is a central uncertainty, especially for Asian robusta. More than half of global robusta comes from Vietnam, Indonesia and India, regions historically prone to reduced rainfall under El Niño. Recent regional climate outlooks point to below‑normal rainfall over much of southern ASEAN and drier‑than‑average conditions for Vietnam in late 2026, consistent with a strengthening El Niño through year‑end.

While BMI judges that earlier 2026 rainfall patterns pose limited risk to the 2026/27 crop, the real vulnerability lies in the 2027/28 cycle. If dryness reduces water reserves ahead of the key fruit‑setting and bean‑development window in Q2 2027, robusta yields could underperform expectations. At the same time, producers in origins such as Ethiopia, Honduras and Nicaragua face higher fertiliser costs following geopolitical tensions, which may curb input use and cap yield potential even where weather is more neutral.

Outlook 2026–2027

The market is likely to split into two distinct phases. Through late 2026 and early 2027, the arrival of Brazil’s large 2026/27 crop and faster export flows could generate episodes of downward pressure or consolidation in futures, particularly if quality concerns are contained and logistics perform smoothly. Market participants already note that Brazilian shipments at the season’s start are stronger than last year, albeit constrained in some areas by earlier rains.

Beyond that window, focus will pivot to the combination of a smaller 2027/28 Brazilian crop, potential El Niño‑related stress in Asian robusta and a narrowing global surplus. Under this scenario, current BMI forecasts of an average 307 cents/lb in 2026 point to sustained price support into 2027, with upside risk if robusta losses or Brazilian yield downgrades materialise. In essence, the market may briefly relax as the Brazilian harvest clears, but the structural tightness story remains very much alive.

Trading & Risk Management View

• Roasters: Use potential Q4 2026–Q1 2027 price softness, driven by heavy Brazilian arrivals, to extend cover into mid‑2027, especially for robusta‑heavy blends. Prioritise origins with lower El Niño exposure where possible.
• Producers in Vietnam/Indonesia: Consider incremental hedging on rallies above the mid‑300s cents/lb area, but retain flexibility given elevated downside production risk from 2027/28 weather. Monitoring soil moisture and local input costs will be key to calibrating sales.
• Traders/Specs: The backdrop favours buying medium‑term dips rather than chasing spikes. Option structures that finance upside exposure (e.g., call spreads) may be attractive ahead of the main El Niño‑sensitive flowering and fruit‑set period in early 2027.
• Risk focus: Track El Niño intensity indicators, rainfall anomalies in Vietnam’s Central Highlands and Indonesian coffee zones, Brazil’s 2027/28 arabica flowering, fertiliser price trends, and any revisions to surplus estimates.

Short‑Term Regional & Price Direction (Next 3 Days)

• ICE futures: With the Brazilian harvest essentially completed and weather turning seasonally drier, price action over the coming days is likely to be range‑bound to slightly softer as supply headlines dominate and El Niño fears remain more medium‑term.
• Vietnam FOB robusta: Local offers around EUR 4.0–4.4/kg are expected to stay broadly steady, supported by exporter coverage needs but capped by abundant global arabica availability.
• Brazil export basis: Basis levels may ease marginally as more 2026/27 coffee reaches ports, though any quality downgrades or logistical bottlenecks could quickly reinject volatility.
