Coffee Prices Sharply Lower on the Outlook for Ample Supplies

Arabica futures fell 2.28% to a three‑week low and robusta dropped 2.65% to a four‑month low as coffee prices extended a two‑week decline; ample rains in Brazil and stronger supply data have turned the market bearish. Weather services and Conab’s upward revision to Brazil’s 2025 crop (to 56.54 million bags), large increases in Vietnamese exports (Nov +39% y/y; Jan‑Nov +14.8% to 1.398 MMT) and Vietnam’s projected 2025/26 output (+6% to 1.76 MMT) are weighing on prices, while USDA/FAS expects record global production in 2025/26 (+2.5% to 178.68 million bags) with robusta up sharply. Offsetting forces are recent low ICE inventories for arabica and robusta and the easing of U.S. tariffs that could revive demand, leaving near‑term direction dependent on weather developments and demand recovery.

Analysis

Arabica March futures closed down 8.20 cents (-2.28%) to a three‑week low and January robusta fell 107 points (-2.65%) to a four‑month low as coffee prices extended a two‑week slide. The immediate bearish trigger was weather: Climatempo forecast "intense and persistent" rainfall in Brazil’s coffee regions and Somar reported Minas Gerais received 79.8 mm for the week ended Dec. 12 (155% of the historical average), easing crop development concerns.

Supply-side data reinforce the bearish case: Conab raised Brazil’s 2025 coffee estimate 2.4% to 56.54 million bags from 55.20 million, Vietnam’s Nov exports rose 39% y/y to 88,000 MT and Jan–Nov exports are +14.8% y/y to 1.398 MMT, and FAS projects world 2025/26 production +2.5% to 178.68 million bags with robusta up 7.9%. Offsetting factors include low ICE-monitored arabica inventories (1.75‑year low of 398,645 bags on Nov. 20, recovering to 426,523 on Dec. 5) and robusta inventories near 11.5‑month lows, plus eased U.S. tariffs that could revive demand after a 52% drop in U.S. purchases Aug–Oct.

Implication: near‑term price bias is bearish given heavier rain and stronger export flows, but the market remains vulnerable to upside if inventories stop rising or demand recovers; key near‑term risks are changes in Brazilian weather, Vietnam production/outturn surprises, and weekly ICE inventory and export flow updates that would alter the supply/demand balance.

Key Decisions for Investors

• Reduce near‑term long exposure to arabica and robusta futures or tighten stops given recent sharp declines, heavy Brazilian rains and Conab's +2.4% Brazil output revision
• Use hedged structures (protective puts or short futures with call protection) to limit downside while retaining upside exposure if inventories tighten or demand recovers
• Monitor three triggers closely—Brazil rainfall outlook, weekly ICE inventory reports, and Vietnam export/production releases—and only re‑establish material long positions if those indicators turn adverse to supply
• Consider small selective short or cash allocations in commodity books while volatility and directional uncertainty remain elevated
