Walnut Kernels Edge Higher as Heat and Tight Stocks Support Prices

Spot walnut kernel prices in China, the US and India are edging higher, supported by tighter old-crop stocks and weather concerns in key producing regions. Recent gains are modest but broad-based across major grades, signaling a firmer undertone ahead of the 2026/27 marketing season. Walnut markets are in a seasonally quiet window, but price signals are turning mildly bullish. In China, FOB Dalian prices for light quarters and pieces have ticked up over the last week as exporters report steady offshore interest and limited willingness to discount. In the US, California growers face an intense heatwave that adds risk to nut fill and quality, while India’s Kashmir-origin crop approaches bloom under generally normal summer conditions but with longer‑term structural pressure from rising imports. Against this backdrop, nearby price downside appears limited, with buyers advised to cover short-term needs on dips rather than wait for significant corrections.

Prices

All prices converted approximately to EUR (EUR/USD ≈ 1.10; EUR/INR ≈ 92) and rounded.

Chinese prices are leading the firming move, with all tracked grades up about 0.05 USD/kg versus late July. US and Indian organic halves show similar, though slightly smaller, week-on-week increases. The structure suggests a mild tightening of nearby supply rather than a speculative spike.

Supply & Demand Drivers (CN, US, IN)

China (CN)

China remains the largest walnut producer globally, with 2025/26 kernel-basis output estimated around 1.5 million metric tons, representing over half of world production. Exporters currently draw down remaining 2025 crop stocks while new-crop harvest is still several weeks away in many northern provinces. This inter-harvest period typically supports FOB prices as pipelines run thin.

Logistics out of North China ports are functioning normally, but higher global bunker fuel costs and geopolitical tensions have lifted freight rates on some Asia–EU lanes, indirectly underpinning FOB offers. Chinese walnuts continue to face competition from cheaper Chilean and US-origin product in some destinations, yet buyers with color‑critical specifications (light quarters/pieces) show limited replacement options, adding to price resilience.

United States (US)

California is the second-largest walnut producer, with 2025/26 kernel-equivalent output projected above 730,000 metric tons, sharply up from the previous season. However, the state is currently under an intense heatwave tied to a large heat dome and El Niño conditions, with temperatures in parts of the Central Valley and Northern California expected to exceed seasonal norms through the coming days.

High temperatures during nut fill can increase tree stress and raise the risk of smaller kernels or quality defects if accompanied by water constraints. Existing research and climate assessments for California highlight that persistent heat also favors pests such as navel orangeworm, potentially raising damage rates in walnuts and other nuts. While it is too early to quantify yield loss, this weather backdrop supports a risk premium in forward price ideas.

India (IN)

India is a mid-sized walnut producer (around 30,000 metric tons kernel basis in 2025/26) with Kashmir accounting for roughly 90% of domestic output. Domestic production has struggled to keep pace with consumption growth, and imports have expanded significantly over the last decade, notably from the UAE (re-export hub) and other origins.

Available official and trade data up to mid-2026 point to steady demand for premium kernels in North Indian metros, while local traders in Jammu and Kashmir increasingly focus on higher-quality grading and export channels. No major adverse weather events have been reported for the current summer in Kashmir in the last few days; conditions are seasonally warm and broadly supportive of orchard development. However, the sector remains structurally vulnerable to erratic monsoons in hilly states.

Fundamentals & Weather Outlook

Global balance

Latest international nut industry figures for 2025/26 show world walnut production rising to roughly 2.83 million metric tons (kernel basis), up about 8% year-on-year, with China, the US and Chile driving most of the growth. Despite higher supply, projected ending stocks remain moderate at about 130,000 metric tons, equivalent to less than 5% of use, indicating that the market is not excessively oversupplied.

This lean stock-to-use ratio helps explain why prices can firm seasonally even when headline production numbers look comfortable. The combination of inventory management by processors, quality differentiation, and region-specific weather risks is more important for short-term pricing than absolute global output.

Short-term weather (next ~3 days)

• CN: Northern China walnut areas are forecast to see typical August heat with scattered showers, but no widespread extremes flagged in the last three days of reporting. This should allow orchards to progress normally while maintaining some support for old-crop prices as farmers await clearer new-crop sizing.
• US (CA): Forecasts call for continued above-normal temperatures across much of California, including the Central Valley, under a persistent heat dome and related heat advisories into early next week. Orchard water management will be critical to protect kernel fill and minimize sunburn.
• IN (Kashmir/Himalayan states): No specific extreme weather alerts for walnut belts have emerged in the last three days. Conditions appear seasonally warm with ongoing monsoon activity in the wider region, which is typical for this time of year and broadly supportive of tree growth, albeit with localized risks of heavy rain.

Trading Outlook & 3-Day Price Indications

Trading outlook (short term)

• Buyers (importers/processors): Consider covering near-term physical needs now for CN origin, especially light quarters and high-color pieces, as inter-harvest tightness and firm freight may keep FOB levels supported. Stagger purchases for US and IN origins until after clearer assessments of the California heat impact and India’s new-crop prospects.
• Shellers/exporters in CN: The modest upward trend justifies holding firm on offers for higher grades but staying flexible on broken and amber pieces to maintain flow. Monitor freight quotes closely; any easing in container rates could invite opportunistic buying from Europe and the Middle East.
• End‑users/retailers: Forward coverage beyond Q4 2026 can remain moderate for now. With global production up and no confirmed large-scale weather damage yet, extended aggressive hedging seems premature, but short-term promotional buying should be priced quickly before further heat-related headlines.

3-day regional price indication (directional)

• CN – FOB Dalian kernels: Prices likely to trade steady to slightly firmer in EUR terms (±1–2%), supported by limited old-crop stocks and stable export demand.
• US – CA origin kernels (FOB EU hubs): Indicative values seen steady to marginally higher as the ongoing heatwave sustains a weather risk premium, though ample forward crop expectations limit sharp gains.
• IN – FOB New Delhi kernels: Prices expected to remain mostly steady in EUR, with modest upside risk if import offers tighten or if early orchard/weather news from Kashmir turns less favorable.
