Global Walnut Market Update Q4/2026: A Changing Supply Landscape

K-SALES MARKET INSIGHTS | OCTOBER 2026

California’s smaller harvest, China’s expanding production, Chile’s advanced sales position and mixed European crop prospects are reshaping the international walnut market.

The global walnut market is entering the 2026/27 season with contrasting developments across the main producing regions. While California is expecting a significantly smaller crop, China continues to expand production. Chile has already marketed a substantial share of its 2026 harvest, while European origins face varying harvest conditions.

For European importers, food manufacturers and distributors, the coming months will be particularly interesting. Overall production volumes remain important, but kernel colour, size, quality and export availability are likely to play an increasingly decisive role in purchasing decisions.

California: Smaller crop could support firmer prices

California, one of the world’s leading exporters of walnuts, is heading into the new marketing season with a considerably smaller crop forecast.

According to the USDA’s October 1, 2026 Objective Measurement Report, California walnut production is estimated at 680,000 US short tons, approximately 617,000 metric tonnes, compared with 809,000 US short tons in 2025. This represents a year-on-year decline of approximately 16%.

The reduction is mainly reflected in a lower number of walnuts per tree. The USDA survey recorded an average of 796 nuts per tree, compared with 972 in the previous year.

Following several seasons characterised by considerable supply and pressure on grower returns, the smaller crop could contribute to firmer market conditions.

However, the final outcome will depend on actual harvest receipts, kernel quality and demand from major export markets. California’s initial crop estimates have differed from final production in previous years, making it important not to treat the current forecast as a final harvest figure.

For European buyers, the main considerations will be the availability of light-coloured Chandler kernels, commercial sizing and the development of export quotations during the first months of the new season.

China: Growing production increases its influence on global prices

China remains the world’s largest walnut producer and is becoming increasingly relevant to international walnut trade.

In its October 5, 2026 Tree Nuts Annual report, the USDA forecasts Chinese walnut production at 1.6 million metric tonnes for marketing year 2026/27, representing an increase of approximately 7% compared with the previous season.

Favourable growing conditions in major producing regions have contributed to this positive outlook.

China’s large domestic market continues to absorb substantial volumes, but its production capacity also makes it an important competitive factor in international trade.

For importers, Chinese walnuts can represent an alternative source of kernels, particularly in price-sensitive applications. However, comparisons should consider more than the quoted price: kernel colour, consistency, sorting, documentation and food safety requirements remain essential.

The combination of increasing Chinese production and reduced Californian output could create more differentiated market conditions in the 2026/27 season, with prices potentially developing differently across origins and grades.

Chile: Advanced sales and limited remaining availability

Chile continues to strengthen its position as a key Southern Hemisphere supplier, particularly for high-quality walnut kernels.

The 2026 Chilean harvest was estimated to be approximately 5–10% below the previous season, although growers reported generally favourable kernel characteristics, including colour and quality.

Commercialisation has progressed steadily throughout the year. According to ChileNut, approximately 85% of the season’s production had been committed by mid-September, and around 70% was expected to have been shipped by the end of September.

This indicates a relatively advanced sales position as the Northern Hemisphere harvest reaches the market.

Export demand has also evolved differently across product categories. Shipments of in-shell walnuts have weakened in certain periods, while exports of shelled kernels have shown greater resilience. India remains an important destination for Chilean in-shell walnuts.

For European buyers, Chilean walnuts remain an attractive option due to their seasonal availability, kernel quality and established export infrastructure. However, with much of the 2026 crop already committed, remaining offers may become more selective, particularly for preferred grades.

France: Mixed harvest prospects and pressure on local producers

France remains an important European walnut origin, with production concentrated in the Grenoble and Périgord regions.

The 2026 growing season has brought different challenges depending on the region. In southwestern France, intense summer heat and storms have caused damage in some orchards, reducing earlier expectations of an exceptionally good harvest.

In the Grenoble region, the outlook appears more encouraging. Despite periods of heat and limited rainfall, producers have reported relatively favourable conditions, particularly in irrigated orchards.

Industry representatives have indicated a possible harvest of approximately 11,000–13,000 tonnes for the Grenoble protected-origin production area. This remains an indicative assessment rather than a confirmed harvest result.

French walnut producers continue to face structural challenges, including rising production costs, ageing orchards and competition from imported walnuts.

For European food manufacturers, French walnuts remain particularly interesting where regional origin, traceability and product differentiation are important. However, their competitive position in bulk industrial applications continues to depend heavily on price and quality.

Eastern Europe: Regional opportunities with varying supply conditions

Eastern Europe remains a relevant sourcing region for European walnut buyers, particularly for shelled kernels.

Moldova, Ukraine and Romania play different roles in regional supply and trade. Compared with the large, highly mechanised production systems of California, parts of the Eastern European industry remain more fragmented, with production collected from smaller orchards and individual growers.

Moldova is expecting a generally favourable 2026 walnut harvest, according to its Walnut Growers Association. However, production prospects vary depending on orchard management, irrigation and maintenance. Early harvesting had already started in September.

Ukraine remains an established supplier of walnut kernels to European markets. Production is traditionally based to a significant extent on smaller farms and individually harvested trees, although commercial orchards have also developed. Aggregation, processing and sorting therefore play an important role in export consistency.

The ongoing war also remains a factor in assessing Ukrainian sourcing, particularly with regard to logistics and supply continuity.

Romania and neighbouring producing countries, including Bulgaria, Serbia and Hungary, provide additional sourcing opportunities. Their commercial significance depends on local harvest volumes, processing capacity and the ability to supply consistent specifications.

At this stage, sufficiently reliable and comparable 2026 harvest figures are not available for all Eastern European origins. Buyers should therefore assess availability at supplier level rather than assuming a uniform regional trend.

For European importers, proximity and potentially shorter transport routes are important advantages. Nevertheless, product consistency, traceability and food safety documentation remain critical selection criteria.

Global market outlook: What can buyers expect?

The 2026/27 walnut season is unlikely to follow a single global price trend. Instead, supply conditions could lead to increasing differentiation between origins, qualities and product specifications.

Origin 2026/27 supply outlook Market implications
California 16% smaller crop forecast Potential upward price pressure
China Production forecast up 7% Stronger supply and price competition
Chile Most of the 2026 crop committed More selective remaining availability
France Mixed regional harvest prospects Quality and regional origin remain important
Eastern Europe Variable; positive outlook in Moldova Alternative sourcing opportunities

Three factors deserve particular attention during the coming months.

First, the balance between Californian and Chinese supply. California’s smaller crop may support international prices, but China’s increasing production could limit upward pressure in certain market segments.

Second, the availability of premium kernels. Total crop volumes do not necessarily reflect the availability of specific grades. Light and extra-light walnut halves, consistent sizing and low defect rates may command a premium even when overall supply is adequate.

Third, purchasing diversification. With different harvest calendars and market dynamics, combining Northern and Southern Hemisphere origins can help buyers manage availability, quality requirements and purchasing risks.
