Polish Potato Starch Holds Steady as Drought Squeezes European Supply

Polish potato starch prices are holding flat despite tightening European potato supply and firmer raw potato markets, keeping spot values in central Poland broadly stable for now. However, weather-driven yield losses in key EU origins and rising fresh and processing potato prices are starting to build mild upward pressure for Q4 contracts. Across Poland, wholesale table potato prices have climbed sharply since late July on the back of reduced European harvest expectations and strong demand, but starch quotations in Poland remain relatively stable and competitive in a broader EU context. Tight industrial potato supply in Western Europe, combined with ongoing export pull for processed products, is underpinning a firm tone in physical markets and limiting downside for starch. For now, balanced domestic stocks and only gradual demand growth in Poland temper the immediate price response, yet risk is skewed to the upside if EU supply disappoints further.

Prices

Latest wholesale indications for standard table potatoes in Poland are around PLN 1.24/kg as of 7 September 2026, up roughly 18% versus a month ago and more than 40% versus late July, reflecting a strong recovery from summer lows.

Retail and wholesale references for potato starch in Poland suggest a broad wholesale range equivalent to about EUR 0.52–1.10/kg, placing the current central-Poland offer toward the lower half of the European spectrum and underlining Poland’s cost competitiveness.

Supply & Demand

European potato supply for 2026 is under pressure, with industry sources warning that the industrial potato harvest could fall below 40 million tonnes due to reduced plantings, heat and drought. Recent reports highlight notable production declines in France and localized crop losses in southern Europe, such as up to 40–60% losses for quality potatoes in parts of Spain’s Prades region.

In contrast, Italy has reported reasonable overall availability despite below-average yields in some northern areas, while setting a reference price of about EUR 0.50/kg for the new potato campaign, signalling a firm but orderly market. At the EU level, strong demand for frozen potato products and brisk exports outside Europe continue to absorb a large share of processing raw material, constraining the volume available for starch manufacture and keeping underlying fundamentals tight.

Fundamentals & Weather

European potato starch fundamentals are gradually tightening: lower industrial potato availability in major processing hubs and a decline in seed potato area are expected to curb starch raw material supply into the new campaign. While prices in the broader European starch market had trended softer in 2025, recent physical market reports now point to a floor forming, with downside limited by constrained potato supply and steady industrial demand.

In Poland, structural potato output remains solid in a multi-year context, with national potato production recovering above 7 million tonnes in 2025 after weaker 2024 volumes. However, like the rest of Europe, Polish growers have faced episodes of moisture stress and high temperatures this season, particularly during critical tuber bulking phases, which likely trimmed yield potential despite otherwise adequate acreage. This combination supports firm raw potato prices without triggering acute domestic shortages.

Short Weather Outlook (Poland)

For central Poland, including the Łódź region, short-range forecasts for the coming days point to seasonally mild early‑September conditions, with moderate temperatures and scattered showers rather than prolonged heatwaves. This pattern should support late harvesting and handling of maincrop potatoes, while limiting additional drought stress on remaining unharvested fields.

Given that much of the 2026 potato crop is already lifted or near maturity, weather in the next 3–5 days will have limited impact on yield totals but will matter for harvesting logistics and tuber quality in storage. Any heavier localised rainfall could briefly slow lifting but is unlikely to materially change overall supply expectations at this stage of the season.

Trading Outlook

• Buyers (food & industrial users): Consider covering a portion of Q4–Q1 starch requirements at current Polish levels, which remain competitive versus Western European indications amid tightening regional supply.
• Producers & sellers: Maintain a firm pricing stance but stay flexible on nearby deliveries; rising raw potato and energy costs justify small risk premiums, yet demand sensitivity at higher price points should be monitored.
• Traders: Watch European processing potato and frozen product export flows closely; any further downgrades to EU harvest estimates or logistics disruptions could quickly translate into stronger starch replacement demand and higher offers.

3‑Day Price Indication (Poland, Potato Starch)

• Direction: Sideways to marginally firmer over the next three trading days, as stronger table and processing potato prices filter slowly into starch cost bases.
• Range: Spot ex‑factory quotes in central Poland are expected to remain broadly stable in euro terms, with only limited upside of a few eurocents per kg in case of renewed buying interest from EU processors.
• Risk factors: Additional downward revisions to Western European harvest forecasts or unexpected export tenders for processed products could tighten availability and accelerate price appreciation later in September.
