Market Positioning
ICE EU Disaggregated Commitments of Traders — Robusta Coffee Futures (Liffe)
Managed money is moderately long (60th percentile vs. full ICE EU history since 2011), net long 18,066 lots. Note: unlike KC Arabica where commercials reliably run net-short hedges, robusta commercials include active traders who can sit on either side — commercial net position (-15,958 lots, 39th pct) should be read in trend context rather than as a contrarian extreme.

RC Coffee continuous contract ($/t) by week of year. Overlapping years reveal seasonal price trajectory vs prior years.

Managed money net long (long minus short) by week of year — overlapping years since 2011.

Commercial net position (producer/merchant long minus short). In the robusta market the commercial category includes active traders who can be net long, so an upward trend here is worth watching rather than mechanically fading.

ICE Certified Stocks
Deliverable robusta inventory backing the London robusta (RM) contract · ICE certified stock report

ICE Robusta certified stocks — the exchange-graded robusta inventory in licensed warehouses deliverable against the London robusta (RM) contract. Reported in lots (1 lot = 10 tonnes). A sustained drawdown means physical supply tightening relative to demand and is typically price-supportive; rebuilding stocks ease near-term scarcity. Source: ICE certified stock report.

Crop Conditions Overview
CWSI deviation from climatological normal — monthly average, robusta growing regions
Each cell shows the mean crop-water-stress deviation for that month and year. Green = less stress than historical average (favorable) · Red = more stress (drought / heat risk). Vietnam and Brazil robusta have different crop calendars — compare columns within each heatmap rather than across them.

Indonesia Robusta (Lampung / South Sumatra) — harvest May–Sep. Dry season stress Jun–Sep is the key production risk.

Brazil Robusta (Espírito Santo) — harvest Apr–Aug. Flowering Sept–Oct means stress here impacts next year.

Vietnam — main crop harvested Oct–Feb. Key stress window: Jul–Sep dry season before flowering.

Vietnam — Seasonal Detail

CWSI deviation from climatological normal. Vietnam's main robusta crop is harvested October–February (off-season Jul–Sep). The Central Highlands (Dak Lak, Lam Dong) receive most rainfall Apr–Oct. Drought stress in the July–September dry season is the key production risk.

Brazil Robusta — Seasonal Detail

CWSI deviation from climatological normal. Espírito Santo produces ~80% of Brazil's robusta. Harvest runs April–August. Flowering in September–October means late-season stress has outsized impact on the following year's crop.

Indonesia Robusta — Seasonal Detail

CWSI deviation from climatological normal. Indonesia is the world's third-largest robusta producer. Lampung (South Sumatra) and Flores are the key growing regions. Main harvest runs May–September. The dry season (June–September) during cherry development is the primary weather risk.

Origin Deforestation Risk
GFW GLAD alerts · Vegetation stress · Supply chain data — Robusta growing regions
Deforestation risk index for each robusta growing region, combining Global Forest Watch GLAD deforestation alert area, CWSI vegetation stress, and Trase supply chain data. This index reflects regional land-use pressure — not your specific supplier's compliance status. Source: Global Forest Watch, Trase.earth, ERA5-Land.
