Global food supply concerns have intensified dramatically, triggering a wave of limit-up trading in China's A-share agricultural sector even as analysts warn that valuations for several stocks have become detached from fundamental performance.
On September 8, Yasheng Group (600108.SH) locked in its fourth consecutive daily limit-up, while Jinjian Rice (600127.SH) closed up 9.3%, bringing its cumulative gains since August to over 139%. Other names including COFCO Technology (000930), COFCO Sugar (600737), and Dunhuang Seed (600354) also hit their daily trading limits.
The immediate catalyst behind this surge is significant macroeconomic turbulence. The strongest El Ni帽o event in 150 years threatens production cuts across major growing regions, pushing Chicago Board of Trade (CBOT) futures for soybeans, corn, soybean meal, and wheat to fresh multi-month highs. Additionally, stalled Black Sea grain shipments and disruption to shipping through the Strait of Hormuz have driven the UN Food and Agriculture Organization's food price index to its highest level since November 2022.
Where the expectations meet reality
Guotai Fund analysis suggests this rally is not merely a reaction to a single crop price increase but rather a repricing of systemic expectations for higher global agricultural prices. "The root cause of international grain price increases is a sharp contraction in supply, but domestic grain prices in China remain stable due to policy support," noted an industry insider. The same observer cautioned that after consecutive gains, valuations for many agricultural stocks have moved significantly beyond underlying fundamentals, building substantial profit-taking pressure.
The World Meteorological Organization confirmed on September 3 that the strongest El Ni帽o in 150 years has emerged and is expected to strengthen to "super" levels in coming months, with an almost certain probability of persisting until February 2027. This rare forecast has sharply tightened supply expectations worldwide. The FAO has cut its 2026 global grain production forecast by 3.4 million tonnes to 2.98 billion tonnes, a 2.0% year-on-year decline and the largest annual drop since 2018.
Extreme heat across Europe has already damaged approximately 9 million tonnes of wheat, barley, and corn, while persistent dry conditions in parts of the US Corn Belt cloud autumn harvest prospects. On commodity exchanges, CBOT November soybean futures climbed from 1200 cents per bushel to 1310 cents per bushel between August and September 7. December corn futures rose from 460 cents to 537 cents per bushel, December soybean meal futures advanced from $310 to $354 per short ton, and December soybean oil futures moved from 65 cents to 70 cents per pound.
Speculative money has amplified these price swings. CFTC data shows non-commercial net long positions increased by 31,482 contracts to 247,033 in the week ending September 1, representing 5.2% of total open interest of 470,560 contracts. Meanwhile, major financial institutions are sounding alarms: JPMorgan warns of a potential global food crisis next year, HSBC flags the first supply-demand deficit in global grain for 2026-2027 since 2020-2021, and Citi has raised price targets across corn, wheat, and soybeans.
The gap between strong expectations and weak fundamentals
As speculative enthusiasm meets soft spot-market conditions, questions arise over how long the agricultural rally can persist. Leading the charge, Jinjian Rice has achieved eight limit-up sessions across 17 trading days, lifting its market capitalization from under 4 billion yuan to over 9.5 billion yuan. The company itself acknowledged that while market narratives focus on "super El Ni帽o" and "grain concept" themes, its actual terminal price movements remain limited and the earnings impact of such narratives is highly uncertain.
Between August 17 and September 1, Jinjian Rice shares triggered abnormal volatility alerts three times, with cumulative turnover reaching 371.68% over 12 trading sessions, a clear sign of speculative "pass-the-parcel" trading. The company's first-half 2026 results showed a net loss attributable to shareholders of 9.5791 million yuan, swinging from profit to loss year-on-year. Rising crude oil prices have pushed up raw material costs, but the company has been unable to pass through price increases to consumers at the same pace, compressing margins in its oils and fats segment.
Similarly, Yasheng Group posted first-half revenue of 1.472 billion yuan, down 2.63% year-on-year, with attributable net profit of 24.9188 million yuan, a decline of 11.01%. Despite four consecutive limit-up sessions and a market value exceeding 10 billion yuan, the company's fundamentals are deteriorating on both metrics. Its September 7 risk warning notice highlighted that the stock price has risen sharply in a short period.
Analysts point to the fragility of such capital-driven moves. Fang Hui, chief agricultural commodity analyst at Orient Futures, notes that while El Ni帽o provides the narrative backbone for stronger futures prices, the more dominant force is an influx of speculative capital amplifying the weather-themed "strong expectations" even as physical spot supplies remain relatively abundant. "Extreme speculative positioning not only pushes prices higher but also means any negative news could trigger a sharp correction," she cautioned.
Limited transmission to domestic markets
Amid the market excitement, policymakers are signaling longer-term structural reforms. On September 7, six government departments jointly issued a plan to improve investment mechanisms for rural revitalization, explicitly proposing for the first time inter-provincial horizontal benefit compensation for grain production and sales areas. The plan also supports agricultural enterprises in seeking public listings, promotes establishment of rural revitalization funds, and enhances full-cost insurance and planting income protection for rice, wheat, corn, and soybeans.
Guosheng Securities believes that heading into the 15th Five-Year Plan period, agricultural policy priorities are shifting from defending supply bottom lines toward raising production capacity ceilings, with sector positioning evolving toward a "security plus growth" dual-driver logic.
However, the transmission of international grain price spikes to China's domestic market remains muted. China's rice imports primarily come from Southeast Asia under a tariff-rate quota system, with import volumes accounting for only a small share of domestic consumption. The domestic rice market remains oversupplied, with limited upward momentum for prices. Analysts at Zhuochuang Information note that the pass-through effect of global price surges may be considerably diminished domestically.
In the sugar segment, the Thai Sugar Millers Association projects output could fall below 10 million tonnes for the 2026-2027 crushing season starting October. China Galaxy Securities research suggests that drought-driven raw sugar price increases may prompt food and beverage manufacturers to increase substitution with artificial sweeteners, potentially boosting demand for fourth-generation acesulfame potassium and fifth-generation sucralose due to their superior sweetness-to-price ratios, safety profiles, and stability.
Guosheng Securities further notes that the tightening global supply-demand balance for grains, amplified by climate and geopolitical disruptions in major production areas, supports an upward trajectory for international grain price centers. Yet domestic prices remain stable thanks to policy support, high self-sufficiency rates in staple grains, and a solid supply base with continued output expansion driven increasingly by yield improvements rather than acreage growth. Additionally, accelerated commercialization of biological breeding and transgenic technology is opening new growth avenues.
