Polish Potato Starch Edges Lower as Heatwave Meets Strong Early Supply

Polish potato starch prices in Łódź have eased slightly in late June, reflecting strong availability of raw potatoes and muted export excitement, even as a severe heatwave builds over central Poland. The modest downtick suggests a market that is well supplied in the near term, with processors under little pressure to bid higher. Domestic fresh potato markets have shifted rapidly into new-crop mode, with young Polish potatoes dominating wholesale trade and import origins pushed to the margins. Abundant local supply in central Poland is weighing on tuber prices, which in turn cushions starch production costs and limits upside in starch quotations for now. At the same time, extreme heat over the coming days warrants close monitoring for any stress on later fields and potential quality implications for industrial processors.

Prices

Spot potato starch ex-Łódź (FCA) is indicated around EUR 0.66/kg, down about 3% from late May, with the latest move a small step lower from mid-June levels. This drift contrasts with generally firm but not spiking fresh-potato prices, where farmgate averages in Poland are near EUR 0.22/kg, only slightly higher year-on-year.

On the fresh side, wholesale prices for young potatoes near Warsaw (Bronisze) have fallen in recent days to roughly EUR 0.35–0.47/kg for key domestic varieties as local supply has surged and imports from Egypt and Cyprus have lost importance. This soft tone in the raw material market helps explain the mild pressure on starch offers despite strong energy costs and general food inflation.

Supply & Demand

Poland remains a significant potato producer and exporter within the EU, with recent data indicating exports above 110,000 tonnes and a growing role in regional trade. Current wholesale reports show domestic new-crop potatoes now dominating central Polish markets, with last season’s stocks largely irrelevant and import shares much reduced.

For starch processors, this means good access to competitively priced raw material at the start of the 2026/27 campaign. European processing potato benchmarks remain subdued after a steep correction earlier in June, signalling a generally well-supplied industrial segment despite local weather risks. Demand from food and paper industries is stable but not booming, and no major logistical disruptions or policy shocks have emerged in the last few days to tighten supply.

Weather & Crop Conditions (PL)

The Łódź region faces a pronounced heatwave over the next three days, with maximum temperatures forecast around 32–40°C and an official orange heat warning in place as temperatures above 30°C are expected to persist at least until Monday. Soil moisture had been generally adequate into early June across much of Poland, supporting a rapid harvest of early potatoes.

Short term, the heatwave is unlikely to tighten potato starch supply immediately, as processors can lean on existing early-harvest stocks. However, sustained high temperatures without compensating rainfall could stress non-irrigated later fields, reducing tuber size and potentially increasing dry matter content, which would be a mixed outcome for starch: supportive for quality but carrying upside risk for raw potato prices later in the season.

Fundamentals

National statistics indicate that Polish potato output recovered strongly in 2025 to around 7.0 million tonnes, exceeding 2024 volumes and providing a comfortable baseline for 2026 starch operations. While the detailed 2026 crop forecast is not yet finalized, spring assessments and external market outlooks point to mostly favourable sowing and establishment conditions, including in Poland.

On the demand side, there is no sign of a sudden surge from export or specialty segments in the last three days. Broader EU early-potato markets are described as calm, with limited industrial and export demand at EUR 2.00/100 kg for bulk early potatoes in neighbouring Belgium, signalling a generally soft tone across the processing chain. In this environment, small price discounts on starch are enough to clear volumes without triggering aggressive competition among Polish processors.

Short-Term Outlook & Strategy

Over the next week, the key balancing factors for Polish potato starch will be persistent heat in central Poland, ongoing strong availabilities of early potatoes, and still-muted EU processing demand. As long as weather stress does not translate into visible deterioration of crop prospects, the bias remains for sideways-to-slightly softer starch quotations from current levels.

• Buyers / Users: Consider covering near-term starch needs on spot or short-term contracts while prices hold around EUR 0.66/kg; scale in additional purchases only if heat persists without rain into July, signalling potential later-crop stress.
• Processors: With raw potato prices under pressure, margin protection is currently favourable; avoid deep price cuts on starch and focus on securing quality tubers ahead of prolonged heat.
• Farmers: In regions hit by the heatwave, prioritise irrigation and soil moisture conservation where possible; monitor contracts linked to starch quality parameters, as higher dry matter from heat-stressed crops could become a negotiation point.

3‑Day Price Indication (PL, potato starch)

• Łódź FCA: Bias for flat to slightly softer pricing around EUR 0.65–0.67/kg over the next three trading days, barring a sudden deterioration in crop condition reports.
