Tight US Crop and El Niño Risks Put Global Potato Market on Alert

US potato supply is heading into a structurally tight season, with the 2026 crop projected well below last year and the five‑year average. Strong El Niño signals raise additional risks for storage losses in key northern regions, potentially amplifying the impact of the small crop. Fresh market prices for key russet varieties are already elevated, and processors are starting to secure raw material early for 2027. Across Europe, table potato quotations are firm but stable, and potato starch prices in Poland are flat. However, if North American supply tightens further or if storage problems materialise, global trade flows and processed potato markets could see renewed upward price pressure later in the season.

Prices

In the US, fresh potato prices, especially for Russet Norkotah, are clearly above last year as packing houses compete for limited volumes of good quality crop. This is confirmed by recent shipping point data, with Idaho Russet Norkotah prices holding at elevated levels and vendors warning of tighter supplies into the coming weeks.

European table markets are comparatively calm but firm. Recent quotations show:

• PCA Fontane (13.10.2026): 20.00 EUR/dt FCA
• PCA Challenger (13.10.2026): 20.00 EUR/dt FCA
• PotatoNL Kat01 (12.10.2026): 24.00 EUR/dt
• PotatoNL Kat02 (12.10.2026): 27.00 EUR/dt
• PotatoNL Regular (12.10.2026): 21.00 EUR/dt
• Reka Niedersachsen (firm, 09.10.2026): 27.00 EUR/dt
• Reka Rheinland (firm to mealy, 09.10.2026): 30.00 EUR/dt
• Reka Rheinland-Pfalz (firm/mealy, 09.10.2026): 33.00–35.00 EUR/dt

In ingredients, potato starch ex Lodz, Poland (FCA) is quoted at 0.625 EUR/kg, unchanged in all updates since early September, indicating a stable but cautious industrial demand environment.

Supply & Demand

The US industry faces a significantly smaller 2026 crop. Current projections point to around 17.9 million tonnes, down about 0.83 million tonnes (−4.4%) versus 2025 and roughly 5.5% below the five‑year average. This would be the smallest US harvest since 2010, tightening the balance sheet across fresh, processing and export channels.

Idaho and Washington remain in focus, as both states account for more than half of US production and are awaiting confirmation or revisions in the upcoming October USDA crop report. Summer heat in the Columbia Basin has already depressed yields, and processors, particularly French fries manufacturers, are expected to secure raw material early for the 2027 campaign, further competing with the fresh sector.

On the demand side, consumer and foodservice uptake of potatoes and potato products remains solid. Recent distributor updates highlight ongoing strong demand for large russet counts, with especially tight availability of 40–70 count sizes as fresh-run stocks give way to storage supplies.

Fundamentals & Risks

The fundamental story is increasingly shaped by weather and storage risks rather than acreage alone. NOAA’s latest ENSO Diagnostic Discussion confirms a strong-to-very-strong El Niño, with more than an 83% probability that historically exceptional conditions will prevail from October to December 2026 and persist into early 2027.

For northern North American storage regions, industry organisations warn that a milder winter would reduce natural cooling potential. This implies higher energy costs for forced cooling and ventilation, as well as elevated risks of pressure bruising, diseases, shrink, earlier sprouting and shortened storage life. In a year with an already tight crop, every tonne lost in store has an outsized impact on availability and price stability.

Market intelligence from US shippers indicates that while total crop size may not signal an acute shortage everywhere, localized tightness in large, high‑quality russets is already visible. This is manifested in firm to higher prices for premium packs and could intensify if storage problems emerge later in the season or if quality downgrades reduce packout ratios.

Weather & Storage Outlook

Climate models suggest El Niño will peak around December, with impacts lasting into February 2027. Forecasters emphasise above‑normal temperatures for many northern US and Canadian regions, meaning reduced natural winter cooling for potato storages and potentially more volatile freeze–thaw cycles.

For operators, this translates into a need for more active climate control in warehouses, tighter monitoring of condensation and pressure bruising risks, and potentially higher electricity costs throughout the storage season. Given the small crop, storage strategies must be tailored to lot condition, local weather and individual storage data rather than broad seasonal assumptions. Preserving quality through to late spring 2027 will be crucial in preventing a second‑half supply squeeze.

Trading Outlook

• Fresh packers / traders: Secure forward coverage for high‑quality table potatoes (especially large sizes and premium varieties) where possible. With US supply tight and EU prices firm, upside risk dominates if storage losses rise later in the season.
• Processors (fries, chips, flakes): Consider accelerating contracting for 2027 raw material, particularly in regions affected by summer heat and El Niño‑related winter risks. Build contingency plans for quality‑related downgrades and higher peel loss.
• Industrial users (starch, dehydrated): Use the current stability in potato starch pricing (0.625 EUR/kg FCA Lodz) to lock in part of 2026/27 needs, but retain flexibility in case tight table markets spill over into processing raw material later in the season.
• Growers & storage operators: Prioritise investments in storage monitoring (temperature, humidity, CO₂) and ventilation management. In a tight crop year, minimizing shrink and quality loss can yield more value than marginal spot price gains.

3‑Day Directional Outlook

• Northwest Europe (DE/NL table potatoes): Sideways to slightly firm; recent quotes are stable but tight global fundamentals and storage risk narrative support a mildly bullish bias.
• US fresh russets: Firm; elevated Russet Norkotah prices are likely to hold or edge higher as storage replaces fresh‑run supplies and buyers compete for quality.
• Potato starch (PL, FCA Lodz): Stable; no immediate price pressure, but watch for any shift in processor raw material competition if storage losses in ware potatoes accelerate.
