Where does rice come from?

Rice is a crop of flooded fields. Asian rice (Oryza sativa) tolerates standing water that drowns weeds and most other cereals, so the plant thrives on flat, water-retentive land with a long warm season and a reliable supply of water, whether from the monsoon or from irrigation canals. Those conditions describe the river plains and deltas of monsoon Asia: the Ganges and Brahmaputra, the Yangtze and Pearl, the Mekong, the Irrawaddy and the Chao Phraya. Terraced hillsides and rain-fed uplands add area but far less grain per hectare.

In 2024 India produced 217.9 million tonnes of paddy, 27% of the world's 819.8 million tonnes (FAOSTAT). China came second with 207.5 million tonnes (25%), followed by Bangladesh, Indonesia and Vietnam. Together the top five grew 71% of the total, and 135 countries reported a crop. World paddy output changed by +10% over the ten years to 2024.

The ranking reflects population as much as climate. China and India each feed more than a billion people on a rice-based diet, and most of what they grow is eaten at home. Bangladesh, Indonesia and Vietnam sit on deltas that can carry two or three crops a year under irrigation. Outside Asia, rice matters in Brazil, the United States (Arkansas, Louisiana, California), Egypt's Nile delta, Madagascar and the irrigated schemes of West Africa, but their combined tonnage is small next to the Asian core; countries outside the top ten grew 16% of the 2024 crop.

The FAOSTAT figures above count paddy, the grain still in its husk. Milled white rice, the form that is eaten and traded, weighs roughly two-thirds as much, which is why production and trade tables on this page are not directly comparable.

Only a small slice of the rice crop crosses a border, because the biggest producers are also the biggest eaters. In 2024 world exports of rice (HS 1006, mostly milled) were worth $39.5 billion (CEPII BACI). India was the largest exporter with 30% of that value, ahead of Thailand (17%) and Pakistan (10%). Most of what ships is milled: India led exports of semi-milled or wholly milled rice (HS 100630) in 2024, with 35% of the value, and parboiled, basmati and jasmine rice each move through their own price ladders.

Buyers are scattered. Indonesia was the largest importer in 2024 with 6.8% of world import value, followed by Philippines and Saudi Arabia. Sub-Saharan Africa, the Philippines, Indonesia, the Gulf states and Iran take the bulk of long-grain white and parboiled cargoes, while basmati flows from India and Pakistan to the Middle East and Europe. Because exportable supply is concentrated in a handful of Asian countries, one government's export rule can move prices for every importer.

Rice has no single world price. The market quotes a family of origin-and-grade prices, and the most watched is Thai white rice with 5% brokens, free on board (FOB) Bangkok, which the World Bank carries as Thai 5% broken, Bangkok FOB. In August 2026 that series stood at $471/t, up 26% from a year earlier (World Bank Pink Sheet). Its nominal high was $907/t in April 2008, during the 2008 export-ban panic, and its low since 1960 was $95.7/t in April 1971. Sister quotes track the same grade elsewhere and lower grades in Thailand: Vietnamese 5% brokens at $410.9/t, Thai 25% brokens at $447/t and Thai A.1 Super, an all-broken grade used for feed and brewing, at $452.8/t.

Grade means the share of broken kernels in a sample: 5% brokens is a premium table rice, 25% a cheaper cargo grade, 100% brokens a byproduct. Parboiled rice (steamed in the husk before milling) and aromatic rices (basmati, jasmine) are priced separately and usually higher. A quote is FOB, meaning the price at the loading port with freight and insurance still to add; buyers in West Africa or the Philippines compare cost-and-freight (CFR) landed prices, so ocean freight is part of the origin competition. Government tenders, such as those run by the Philippines, Indonesia's Bulog and Bangladesh, set visible benchmarks for large lots.

The only active exchange contract is CBOT Rough Rice (ticker ZR, 2,000 hundredweight, quoted in US$/cwt), which prices unmilled US long-grain paddy and is thin next to the Asian physical market. Two ambiguities matter when reading this page: production is counted as paddy while trade and prices refer to milled rice, and the Asian FOB quotes are indicative prices assembled by reporters from trader offers rather than an exchange settlement.

Most of Asia's rice depends on the June to September southwest monsoon and its Southeast Asian counterparts. A weak or late monsoon shrinks India's kharif (summer-sown) area and pushes farmers toward shorter crops; El Niño years tend to bring drought to Thailand, the Philippines and Indonesia and salt intrusion into the Mekong delta as river flows fall. Because irrigated deltas can partly compensate, the price effect is felt most through the policy response of exporters rather than through a global shortfall.

India's share of world exports makes its trade rules the single biggest swing factor in the market. Delhi has banned non-basmati exports (2007 to 2008 and July 2023 to September 2024), taxed them, set minimum export prices and prohibited broken-rice shipments (September 2022) whenever domestic prices or the state grain stock looked uncomfortable. Each measure diverts demand to Thailand, Vietnam and Pakistan, whose exportable surpluses are far smaller, so FOB Bangkok jumps even when the world crop is fine.

Rice is stored as paddy and as milled grain by governments as well as traders, and the stocks-to-use ratio (ending stocks divided by consumption) is the cleanest read on how much cushion the market has. USDA put world milled-rice stocks-to-use at 36% for 2026/27, against 37% in 2025/26 (USDA PSD). A large part of world stocks sits in China and India, where they are not available to importers, so the exporters' own stock position matters more than the headline.

A few large buyers can move the market by changing when they buy. The Philippines, Indonesia, Bangladesh and several West African importers purchase through tenders or state agencies, and a run of tenders in a short period, as in the spring of 2008, drains exporters' available cargo and lifts offers for everyone. The reverse also holds: when the Philippines or Indonesia announce a good harvest and pause imports, Vietnamese and Thai prices soften.

FOB prices are quoted in US dollars but exporters' costs are in Thai baht, Vietnamese dong, Indian rupees and Pakistani rupees. A weaker baht lets Thai exporters undercut Vietnam at the same local return, while a strong baht is one reason Thailand lost share after 2011. Importers in Africa face the mirror image: a weaker naira or CFA franc makes the same dollar cargo dearer at home.

Rice is a fertilizer-hungry, irrigated crop, so urea prices and the cost of pumping water and drying grain feed straight into farm margins in Vietnam and Thailand. Ocean freight matters more than for most grains because a large share of rice moves in bags on smaller vessels or in containers to ports in West Africa and the Caribbean. Fuel, container availability and Red Sea or Suez disruptions therefore widen or narrow the landed-price gap between Asian and South American origins.

Rice blast fungus, bacterial blight and brown planthopper outbreaks can cut yields across whole provinces, and planthopper resistance to insecticides has recurred in Vietnam and Thailand. In the Mekong and Ganges deltas the long-run threat is salt water pushing upriver in dry years, which forces farmers to skip a crop or switch to shrimp. Breeding at IRRI and national institutes has delivered submergence-tolerant and salt-tolerant lines, but adoption lags the hazard.

Rice varieties fall into two broad groups. Indica types are long-grained, non-sticky and grown across tropical Asia; japonica types are short or medium-grained, stickier and grown in cooler zones such as northern China, Japan, Korea and California. Aromatic rices sit in between: basmati from the Indo-Gangetic plain and jasmine (hom mali) from northeast Thailand command premiums for scent and grain length. Glutinous rice is a separate market in Laos, Thailand and southern China.

The crop is sown either directly or transplanted as seedlings into puddled fields kept under a few centimeters of water for most of the season. In rain-fed systems there is one crop a year, harvested after the monsoon; in the irrigated deltas of Vietnam, Bangladesh and southern China two or three crops are possible, which is why those countries yield far more per hectare of land than their sown area suggests. Harvest calendars are staggered around the region, so some origin is always cutting new crop.

Milling turns paddy into food. The husk is stripped off first to give brown rice, then the bran layers are polished away to give white rice, and the output is graded by the proportion of broken kernels. Parboiling steams paddy before milling, which hardens the grain, reduces breakage and keeps more nutrients; it is the standard form in much of India, Bangladesh and West Africa. Each step yields a byproduct: husk is burned for heat and power at the mill, bran is pressed for rice bran oil or fed to livestock, and brokens go to brewing, noodles and rice flour. Milled rice weighs roughly two-thirds of the paddy that produced it.

Almost all rice is eaten as grain, boiled or steamed, and it is the daily staple for most of Asia and a growing part of Africa. Processing takes the rest: brokens and flour go into noodles, crackers, baby food and beer as an adjunct starch; polished rice is brewed into sake and other rice wines; bran is refined into cooking oil; and husk and straw fuel boilers, pack goods and feed animals. Rice is rarely used as livestock feed except for broken grades and in years when it is cheaper than corn, which is one reason its price moves independently of the feed-grain complex.

Milling happens close to the fields, because paddy is bulky and spoils if stored wet. Thailand's and Vietnam's export mills cluster along the Chao Phraya and Mekong deltas, where barges carry paddy and milled rice to river ports and on to Bangkok, Laem Chabang, Ho Chi Minh City and Can Tho. India's exporters mill in Punjab and Haryana for basmati and in Andhra Pradesh, Chhattisgarh and West Bengal for non-basmati, shipping from Kakinada, Kandla and Mundra. Pakistani rice leaves from Karachi, US rice from New Orleans and the Gulf, and Brazil and Uruguay ship southern-hemisphere paddy and milled rice to Central America and West Africa.

Rice moves in bags and containers as much as in bulk, so port handling and container supply are chokepoints in their own right. Cargoes to West Africa and the Middle East pass the Strait of Malacca and either the Red Sea and Suez or the Cape, and the 2024 Red Sea attacks lengthened the Asia to Europe and West Africa route. Landlocked importers such as Nepal and the Sahel states depend on a single road or rail corridor from the coast.

The single point of failure is policy rather than geography. Exportable surplus is concentrated in India, Thailand, Vietnam, Pakistan and the United States, and the largest of those has restricted exports repeatedly. A second vulnerability is the Mekong delta, which supplies most of Vietnam's exports and faces upstream dams, subsidence and salt intrusion at once.
