Indian Potato Glut Puts Pressure on Prices While Starch Eases in Europe

India’s potato market is heading into a classic oversupply phase, with West Bengal’s record stocks and near-full cold storages pointing to persistent downward pressure on grower prices and heightened risk of another sharp correction. West Bengal has loaded about 7.4 million metric tons of potatoes into cold storage this season, up 14% year on year and the highest in five years, on total state output above 14 million tons. Storage occupancy above 95% signals a saturated market and constrained liquidity for farmers and traders. Last season’s heavy losses are keeping traders cautious, while a fully liberalized interstate trade regime could slowly improve off‑take. In Europe, potato starch prices in Poland show a mild softening since late April, suggesting comfortable raw material availability and easing processor cost pressure.

Prices & Market Mood

In India, abundant supply and near-saturated cold storages in West Bengal are exerting clear downward pressure on spot and forward potato values. The market is entering a phase where farmers’ bargaining power typically weakens as storage costs accumulate and liquidity needs rise. Trader sentiment remains cautious after last year’s severe price collapse left significant volumes unsold and balance sheets strained.

In Europe, potato starch offers ex-warehouse Łódź, Poland, have eased from around 0.85 EUR/kg in late April to roughly 0.75 EUR/kg by 18 May 2026, indicating improved availability and softer demand from some industrial users. This gentle downtrend, while not dramatic, suggests processors are not currently constrained by raw potato supply and can negotiate slightly better input costs.

Supply & Demand Drivers

West Bengal’s 2025–26 potato production exceeding 14 million metric tons marks a five-year high, supported by favourable weather and a modest area increase. The resulting 7.4 million tons loaded into cold storage — also a five‑year record — have pushed occupancy beyond 95%, a level historically associated with rising selling pressure as the season advances. The fundamental backdrop is one of clear oversupply relative to normal domestic demand patterns.

Despite the bumper crop, trader participation in storage is more conservative than in previous years. The financial pain from last season’s glut, when prices collapsed and large stored volumes could not be cleared, has reduced speculative hoarding. At the same time, the complete removal of interstate movement restrictions by the new state government opens a pathway for stronger flows into neighbouring deficit or price-attractive markets, potentially mitigating but not eliminating the oversupply risk.

Fundamentals & Policy Context

Last year’s market disruption allowed Uttar Pradesh to gain share in key Eastern markets such as Odisha, Jharkhand, and Bihar, traditionally supplied by West Bengal. With West Bengal now liberalising movement of potatoes and other essentials, a more competitive, market-driven trade pattern is likely. This should improve price discovery and reduce regional distortions, but also means West Bengal faces stronger competition and cannot rely solely on regulatory barriers to secure external demand.

The 14% jump in cold storage loading reflects both production success and looming price risk. If domestic table consumption and processing demand fail to accelerate, and if interstate exports do not expand sufficiently, the market could again confront delayed off‑take and forced selling later in the season. For global processors tracking India as a benchmark, the combination of storage saturation and cautious trading underscores how quickly abundant harvests can translate into price corrections and policy pressure.

Short-Term Outlook (2–4 Weeks)

Over the next two to four weeks, potato prices in West Bengal and linked Indian markets are likely to stay under clear downward pressure. Storage saturation above 95% and restrained trader buying reduce the chances of any strong near-term price rebound. Farmers’ willingness to hold stocks may weaken as financing and storage costs mount, increasing the risk of undercutting and localized price dips.

Support could emerge if interstate trade flows pick up meaningfully under the new liberalized regime and if processing demand (chips, fries, starch, flakes) strengthens. However, the main risk remains a repeat of last year’s pattern: slow off‑take relative to record stocks leading to another sharp price correction later in the season. European potato starch prices should remain broadly stable to slightly soft in this window, reflecting comfortable supply conditions.

🧮 Indicative Price Snapshot (EUR)

Trading & Procurement Outlook

• Food manufacturers & processors (EU): Use the current softening in potato starch prices to extend coverage modestly into Q3 while maintaining flexibility in case Indian oversupply deepens global price pressure later in the year.
• Importers of processed potato products: Monitor Indian export offers closely; record West Bengal stocks and liberalized interstate movement could translate into more aggressive pricing from Indian suppliers as the season progresses.
• Indian traders & aggregators: Prioritize early off‑take and diversification into multiple interstate markets to avoid a late-season liquidation scenario. Structured contracts with processors can help lock in volumes and reduce price risk.

3-Day Directional View

• India (West Bengal wholesale potatoes): Mildly bearish; abundant stocks and weak buying interest cap any rallies.
• EU potato starch, Poland (Łódź FCA): Stable to slightly soft, with offers hovering around 0.75 EUR/kg as supply remains comfortable.
• Processed potato products (global benchmark): Largely stable; potential for modest downward bias if Indian oversupply feeds into export pricing later in the season.
