Vietnam Coffee FOB Softens as London Robusta Rebounds

Vietnam coffee export prices eased slightly this week even as London robusta futures rebounded sharply, widening differentials and tempering selling interest from Vietnamese farmers. The market remains under pressure from ample Brazilian supply, but near‑term FOB downside looks limited as local stocks are tight and producers resist further cuts. Vietnamese FOB quotes for both robusta and arabica are drifting lower but remain historically elevated versus pre‑2025 levels. London robusta futures jumped more than 2% on September 25, helped by short‑covering after a multi‑week slide, yet domestic prices in Vietnam have not fully followed the move. With weather in the Central Highlands currently benign and Brazil’s record crop still casting a long shadow, buyers see a window for opportunistic coverage, while sellers eye futures-led rebounds before committing larger volumes.

Prices

Vietnam FOB prices (Hanoi, VN, FOB) as of September 26 show a broad but moderate week‑on‑week decline:

In contrast, London robusta futures (ICE Europe) for the front contract closed around 3,367 USD/tonne on September 25, up 2.43% day‑on‑day after touching a recent three‑month low earlier in the week. This rebound has not yet translated into higher Vietnam FOB offers, leaving differentials slightly softer compared with mid‑September.

Supply & Demand Drivers

Vietnam’s domestic robusta market has been under steady downward pressure over the past week, driven largely by abundant exportable supply from Brazil and rising global stocks. Recent local analyses highlight that record Brazilian robusta (conilon) output and strong export flows have pushed world prices to multi‑month lows, dragging Vietnam’s internal prices to their weakest levels in roughly three months before Friday’s futures rebound.

In Vietnam’s key Central Highlands growing belt, farm‑gate prices in late September remain well below the peaks seen earlier in 2026, reinforcing farmer resistance to selling at current levels. Local reports note sequential daily declines in domestic quotations through September 25, with only modest stabilization thereafter as London futures bounced. This producer reluctance, combined with relatively low carry‑in stocks after heavy shipments earlier in the year, is helping to cap further FOB downside for now.

Weather & Crop Conditions (Vietnam)

Weather across Vietnam’s Central Highlands—the core robusta region—has been largely seasonal in late September, with scattered showers and no major extremes reported in the last few days. Forecasts for the coming week point to typical late‑rainy‑season conditions, with intermittent rainfall and moderate temperatures that are supportive of cherry development and do not currently threaten production.

The absence of acute weather stress in Vietnam contrasts with earlier market concerns around El Niño‑related disruptions. With Brazil also enjoying broadly favorable conditions for its record crop, weather is presently a neutral‑to‑bearish factor for prices, leaving currency moves, speculative positioning and export pace as the main short‑term drivers.

Fundamentals & Spreads

• Futures vs FOB: The latest London rebound has opened a small window where futures prices have risen faster than Vietnamese physical offers, marginally improving hedging opportunities for exporters who are pre‑sold on ICE but still holding physical stock.
• Robusta–arabica spread: Domestic robusta quotations have softened more than arabica in percentage terms, narrowing the arabica premium on a relative basis, though absolute arabica FOB levels in Vietnam remain significantly higher.
• Exporter margins: With internal prices falling faster than FOB offers earlier in the week, margin pressure for exporters has eased somewhat, encouraging selective forward sales, particularly in higher‑grade wet‑polished robusta.

Trading Outlook (Next 3–5 Days)

• Roasters / importers: Consider layering in small additional coverage on Vietnam robusta (both unwashed and wet‑polished) while FOB prices remain slightly discounted relative to the London rebound. Focus on nearby shipments where producer selling is available.
• Vietnamese exporters: Use the firmer London board to lock in margins on existing physical stocks via incremental hedging rather than aggressively cutting FOB offers further. Avoid heavy forward sales until there is clearer confirmation of a sustained futures recovery.
• Producers: With internal prices still under recent lows despite Friday’s futures gains, holding back a share of stocks appears reasonable, but be cautious of further global pressure if Brazil’s strong export pace continues.

3‑Day Regional Price Indication

For Vietnam FOB coffee over the next three trading days (September 28–30):

• Robusta, green, wet polished (scr16 & scr18), FOB Hanoi: Bias for sideways to slightly firmer prices, tracking London if the recent rebound holds, but with limited upside as Brazilian supply remains heavy.
• Robusta, green bean unwashed (scr13–18), FOB Hanoi: Likely to trade steady within a narrow range around current levels, with sporadic discounts if exporters seek to clear low‑grade stocks.
• Arabica, green bean (grades 1–2), FOB Hanoi: Expected broadly stable, with minor adjustments driven more by New York arabica moves than local fundamentals in the short term.
