Tight EU Crop Keeps PotatoNL Firm While Starch Prices Hold Flat

Spot potato prices in Northwest Europe remain firm to slightly upward-biased as tight free-buy supply and a smaller 2026 crop offset the seasonal off‑farm lull, while potato starch prices in Poland stay flat but well supported. Harvest delays and mixed weather keep buyers cautious and underpin PotatoNL quotations across categories. The European potato market in late October is navigating between structurally tighter 2026 supply and processors’ disciplined buying strategies. In the Netherlands, PotatoNL quotations on 26 October show firm to stronger levels, particularly for export and regular grades, underlining ongoing tension in the free market. At the same time, EU starch demand is adequately covered and Polish potato starch offers remain unchanged, signalling that the underlying feedstock tightness has not yet translated into a new price leg higher. In this environment, trade is selective, with buyers prioritising quality and storability and sellers watching harvest progress and logistics risk.

Prices

PotatoNL quotations dated 26 October 2026 indicate a firm market across the main Dutch categories. Category 01 is quoted at 24.00 EUR/dt (range 20.00–28.00 EUR/dt), unchanged from the previous assessment, while Category 02 stands at 28.50 EUR/dt (26.00–31.00 EUR/dt), down modestly by 1.00 EUR/dt, hinting at slight easing in the higher-quality segment.

Regular potatoes are quoted at 22.00 EUR/dt (20.00–24.00 EUR/dt), up 0.75 EUR/dt, and export potatoes at 27.00 EUR/dt (24.00–30.00 EUR/dt), up a notable 2.00 EUR/dt, underscoring robust export‑oriented demand out of the Netherlands. These levels are broadly in line with other Northwest European spot indicators around 20–23 EUR per 100 kg for processing types, confirming a stable-to-firm regional price environment.

In derivatives of the potato complex, conventional potato starch FCA Lodz (Poland) is quoted at 0.625 EUR/kg, with no change across the last three updates through 20 October 2026, reflecting a steady yet well‑supported starch market despite tighter raw potato availability.

Supply & Demand

The 2026 Northwest European potato crop is significantly smaller than recent seasons, with regional estimates pointing to a multi‑million‑tonne shortfall versus normal years due to summer drought and heat stress. Reduced acreage in key producers such as Germany and Poland further constrains the pool of processing potatoes available for starch and fries factories.

On the demand side, European fries exports have been resilient, with near‑record shipments earlier in the season supporting processors’ throughput and underpinning raw potato demand, even as contract coverage remains high. Retail and home consumption are seasonally stable, while peeling and export channels are competing for quality lots, particularly from the Netherlands and Belgium. This tug‑of‑war supports PotatoNL export quotations and limits downside in regular and Category 01 prices.

However, a large share of the 2026 crop is already under contract, creating a two‑tier market: contract volumes are priced below current spot levels, while the free‑buy segment reacts sharply to incremental processor or exporter demand. The result is selective buying of surplus and off‑spec lots at premium spot prices, especially where export logistics require immediate loading.

Fundamentals & Weather

Fundamentals remain tighter than typical for October. Earlier‑season reports highlighted that processors entered autumn with reasonable old‑crop cover but were cautious in the free market, delaying significant spot purchases. As the switch to new crop accelerates, the lower overall harvest and some quality issues (size, dry matter, and storability) point to elevated risk of in‑season shortages in specific segments.

Weather has been highly variable across Northwest Europe. After a drought‑ and heat‑affected summer that cut yields, mid‑October saw harvest progress described as moving "in fits and starts" with too much rain in parts of the Netherlands, Belgium, France and Germany and lingering dryness further south. Recent storms over Western Europe and the British Isles further increased logistical risks, with wet fields and short harvesting windows in some regions.

In this context, quality sorting and storage management are crucial. There is heightened concern that marginal lots may deteriorate in store, further reducing the volume of potatoes fit for processing or export later in the season. This fundamental backdrop justifies the current firm tone in PotatoNL quotations and the stable yet supported level in potato starch prices.

Short-Term Outlook & Trading Ideas

Market outlook (next 2–4 weeks)

• Base case: PotatoNL prices stay firm in all categories, with export and regular quotations biased slightly upward if weather‑related harvest delays persist and export demand remains active.
• Bearish risk: A sustained spell of dry, stable weather allowing rapid completion of lifting could temporarily ease free‑buy tightness, particularly in Category 02, where we already see a mild correction.
• Bullish risk: Further storm systems or quality losses in store could tighten available processing and export stocks, supporting a further rise in export and regular quotations.

Trading guidance

• Processors and packers: Consider securing a portion of open requirements at current PotatoNL levels, prioritising Regular and Export grades where quality is proven, while keeping some flexibility for potential post‑harvest selling pressure if weather improves.
• Growers: With Regular and Export quotations strengthening, avoid aggressive forward selling of top‑quality lots; instead, stagger sales and focus on good storage conditions to preserve optionality later in the season.
• Starch buyers: With FCA Lodz potato starch stable at 0.625 EUR/kg yet underpinned by tighter feedstock, use current flat pricing to extend coverage modestly into Q1 2027, but avoid over‑committing in case demand softens.

3‑Day Directional View

• PotatoNL (all categories): Sideways to slightly firmer; limited volume and ongoing harvest uncertainty should keep quotations within or just above current ranges.
• Northwest EU processing potatoes (spot): Stable to firm as factories transition fully to new crop and free‑buy volumes remain tight.
• Potato starch, FCA Lodz: Steady around 0.625 EUR/kg; no immediate catalyst for a move, but downside appears limited by raw potato availability.
