- JPMorgan economists warn that a “compounding storm” of war, extreme weather and supply chain fragility could trigger a global food crisis by 2027.
- The bank projects global food inflation will accelerate to 5% by the first half of next year, driven by Strait of Hormuz shipping disruptions and a “historic” El Niño.
- Analysts identify India, Colombia, Indonesia, Brazil, South Korea and Taiwan as the most sensitive economies to food price shocks.
- China’s major grain-producing provinces have launched state floor-price purchasing programs in response to rising production costs and global market instability.
- The report emphasizes that food security is now national security, with emerging markets bearing the brunt of potential crop failures and price surges.
Global food shock looms as inflation pressures build
A new report from JPMorgan Chase warns that the next global food crisis may be taking shape, driven by a combination of geopolitical conflict and extreme weather that threatens to destabilize agricultural markets and push food inflation to critical levels by next year. The warning, issued Aug. 15 by senior global economist Nora Szentivanyi, outlines a scenario in which shipping disruptions in the Strait of Hormuz and a potentially historic El Niño converge to weaken crop yields and constrain production capacity.
The analysis arrives amid escalating tensions in the Middle East, where recent U.S. military actions in Syria and ongoing maritime threats in the Red Sea have underscored the fragility of global supply chains. JPMorgan’s report projects global food inflation will accelerate from 2.8% in the first half of 2026 to 5% in the first half of 2027, adding 0.6 percentage points to headline inflation and slowing disinflation efforts worldwide.
The “Five Ws” and fertilizer vulnerability
The JPMorgan report attributes the potential crisis to what analysts call the “Five Ws”: War, Weather, Warehousing, Water and Waste. The most immediate vulnerability lies in the fertilizer supply chain, as the Middle East serves as a critical source of global potash and urea. Any prolonged disruption to shipping routes through the Strait of Hormuz would drive up fertilizer prices, raising planting costs for farmers worldwide and reducing crop yields in subsequent harvests.
Szentivanyi warned that this year’s energy shock could roughly double the inflationary impact of a super El Niño, lifting global food consumer prices by approximately 1.5 percentage points—compared with a historical average increase of 0.7 points. The effects are expected to be concentrated in South and Southeast Asia for rice, sugar and coffee; West Africa for cocoa; and parts of East and Southern Africa, where weather-sensitive agriculture plays a larger role in economic activity and food carries a higher weight in consumption baskets.
China’s policy response and market signals
In response to these mounting pressures, China’s top grain-producing provinces have moved swiftly to stabilize domestic markets. Jiangxi and Hunan provinces activated minimum purchase price programs for early indica rice on Aug. 5, followed by Henan province for wheat on Aug. 11. These state floor-price mechanisms are designed to protect farmers from the double squeeze of falling grain prices and rising input costs, severing what analysts describe as a “vicious transmission chain” that could evolve into systemic risk.
The policy response comes as China’s A-share grain sector staged a broad rally on Aug. 17, with several seed and rice companies hitting daily limit-up thresholds. Since the start of 2026, all four major staple grain varieties—soybeans, corn, wheat and rice—have bottomed and rebounded, with corn leading the advance at a 3.52% year-to-date increase. The synchronized upward pattern reflects growing investor concern over food security and the potential for supply-side contractions.
Global vulnerabilities and market fragility
The JPMorgan warning aligns with similar alarms from other institutional research desks, including Goldman Sachs and HSBC, as well as recent UN Food and Agriculture Organization data showing its global food price index climbing to a three-year high in July. The report cites statistics indicating that 645 million people faced hunger in 2025, while approximately 2.1 billion people—25.8% of the global population—experienced moderate or severe food insecurity.
The report identifies emerging markets as bearing the brunt of potential shocks, with India, Colombia, Indonesia, Brazil, Taiwan and Korea emerging as among the most sensitive economies. Bank of America analyst Robert Ohmes has also warned that another food price spike could arrive in supermarkets this fall, citing a blended index of wages, diesel and commodity costs.
A converging storm
The confluence of geopolitical instability, extreme weather patterns and fragile supply chains presents a formidable challenge to global food security. While China has moved to establish policy floors for grain prices, the broader international community faces a volatile landscape in which agricultural production capacity has been eroded by successive shocks since the COVID-19 pandemic. The JPMorgan report’s conclusion that “food security is national security” resonates as governments worldwide confront the possibility of sustained elevated food prices and the social instability that may follow. As the Strait of Hormuz remains disrupted and El Niño conditions build, the next inflation shock may emerge not at the gas pump, but in the grocery aisle.
