Agriculture looks like the safest asset class on paper. Demand for food is steady, population grows, and people keep eating in a recession. Yet the price of the commodities behind food is among the most volatile in the market. Steady demand does not mean steady prices, because supply is anything but steady. Drought, flood, pests, export bans and wars in grain-exporting regions can change a year's harvest, and with it the price, in a matter of months.
That is why this page looks different from the others. On most of the ten market conditions, the record for agricultural prices is mixed, thin or both. Where the evidence is limited we say so on the verdict itself, and the evidence ledger shows the episodes behind each rating. Treat the ratings below as a summary of a patchy record, not as a set of rules.

"Agriculture" can mean three different investments, and they do not move together. This page's verdicts measure only the first.
- Agricultural commodity prices: the price of grains, oilseeds, sugar and similar crops. Every verdict here is the change in a broad price index in real terms (after inflation), price only: no income, no futures roll yield, no storage costs. The index is the World Bank agriculture price index from 1960 and US farm-product producer prices before that.
- Farmland: land earns rent as well as price changes, and its value depends on interest rates and local conditions. It is not measured here.
- Farm company shares: equipment makers, fertiliser producers and food processors carry debt and operating costs, so they respond to the cycle differently from the crops themselves. They are not measured here.
Results are for a US investor in US dollars. An index is not something you can buy directly; funds that hold futures can return something different from the price index because they have to roll contracts.
The One Rule That Explains Agriculture
Farm prices are set mainly by harvests and by what is in storage afterwards. Demand for food barely changes with the economic cycle, so a supply shock usually moves prices more than a recession or an expansion does. Weather and war tend to beat the cycle. A drought does not wait for a market condition to begin, and the market condition is usually recognised only after the shock has already moved prices.
Timing is the second lesson. In 1972–73 the Soviet Union contracted about 440 million bushels of US wheat, worth roughly US$700 million, and the purchases contributed to sharp rises in grain and food prices. Much of that spike came before the stagflation window that investors now associate with it. In 2007–08 prices peaked in the second quarter of 2008 and then fell dramatically during the recession. In 2022 the FAO Food Price Index peaked in March, a month after the invasion of Ukraine. In these three cases an investor who waited for the market condition to be obvious would have bought after much of the move.

Deep Dive: Agriculture in Every Market Condition
War can lift farm prices through disrupted supply and through government demand. The record shows the rise in one war out of three. US farm-product prices rose about 44% in real terms during World War II (1939–45), but fell about 8% in real terms during the Korean War (1950–53, about 2.7% a year, inside our flat band) and were roughly flat in the Vietnam War (1965–73). With only three episodes, the verdict is the mechanism plus one strong example, which is why the evidence label is Limited.
Agriculture is often described as a real asset, so it is natural to expect it to win in stagflation. The record is more mixed. Most of the big price rise came before the stagflation window. From November 1973 to March 1975 the World Bank agriculture index rose into 1974 and then fell back, ending about 12% lower in real terms. In 1979–80 it ended about 2.5% lower. One window ended clearly lower, with a rise and a fall inside it, and the other ended flat, so the verdict is Mixed on Limited evidence. An investor who waited until stagflation was recognised would have bought after much of the spike.
Food prices are part of inflation, so the link looks obvious. The evidence is thin. US farm-product prices rose about 19% in real terms during the post-war inflation of 1946–47, and fell about 13% in real terms in 1966–69 on the World Bank index (about 2.5% a year on a producer-price check, recorded as flat). The 2021–23 surge cannot be read cleanly: the price indices we cross-checked pointed in different directions, so no reading is recorded for it. One clear rise in three episodes is a reason to keep the verdict modest.
Fear of food shortages can move prices within days, and the FAO Food Price Index peaked in March 2022. But the spike is not the same as the window. Measured over the full period of each crisis, real prices rose about 5% over seven months around the 1962 Cuban Missile Crisis (only just above our 5% threshold) and were flat or lower in the other four: 1990–91, 2001, 2014 and 2022. In the 2022 window, from January to September, the World Bank index was about 7% lower in real terms. One narrow rise, three flat readings and one fall make a Mixed verdict: the fast spike is real, but over the whole crisis it has not shown up as a lasting gain.
Farm prices follow the harvest, not the business cycle. The 2001–07 expansion saw world agricultural prices rise about 69% in real terms, roughly 9% a year. The other three expansions went the other way, slowly. Real prices drifted down about 2.4% a year in 1982–90 (about 17% in total), between roughly 2.4% and 4.1% a year in 1991–2001 depending on the index, and about 2.3% a year in 2009–20 (about 22% in total). All three sit inside or near our flat band of 3% a year, so they are recorded as flat. One big rise and three slow declines make a Neutral verdict with Conflicting evidence.
Recoveries are kinder to farm prices than expansions are. In the first year after the trough, real prices rose in three of six recoveries and were flat in the other three. They rose about 20% after the 1982 trough, about 14% after 2001 and about 25% after 2020, and were flat after 1975, 1991 and 2009. The 1975–76 reading depended on the index used (down about 10% on one, up about 3% on another), so it is recorded as flat. The 1982–83 gain is clear on the World Bank index but only just above our threshold on the cross-check, so the Neutral verdict is cautious rather than certain.
Interest rates are a minor driver of crop prices next to weather and supply. Real prices were flat in three of four hiking cycles (1999–2000, 2004–06 and 2015–18). The exception is 2022–23, when they fell about 20% in real terms. That fall coincided with the retreat from the war-driven price peak, so it says as much about the 2022 spike as about interest rates. The 1994–95 cycle is left out because the price indices disagreed on its direction.
People still eat, but commodity prices still swing. Real prices were flat in four of six recessions (1969–70, 1990–91, 2001 and 2020), fell about 24% in real terms in 1981–82, and in 2007–09 rose more than 20% and then fell more than 25% inside the same window, ending about 4% lower. Steady food demand cushions most recessions without protecting prices from a large fall. This is the best-supported verdict on the page, and it is a Mixed one.
Falling general prices usually hit commodity prices first. This verdict rests on a single episode. US farm-product producer prices fell by over 42% in real terms between January 1930 and March 1933. Japan's deflation from 1998 to 2012 is the other candidate, but we found no usable Japanese farm-price series, so it is recorded as no data. Read the rating as the 1930s experience, not as a pattern across several deflations.
The only measurable depression, 1929–33, took US farm-product prices down about 45% in real terms. That is one episode, and it covers commodity prices, not farmland values or farm incomes. Whatever else a depression does to farmers, the price of what they sell fell steeply in the one case we can measure. The Limited evidence label is the honest summary.
Common Mistakes Agriculture Investors Make
⚠ The Most Costly Agriculture Investing Errors
✗ Buying after the spike. World food prices peaked in the second quarter of 2008 and then fell dramatically during the recession. The FAO Food Price Index peaked in March 2022. A headline about food shortages usually arrives when much of the move has already happened.
✗ Treating steady food demand as a price floor. Demand for food is stable, but prices are set by supply as well. Real agricultural prices fell about 24% over the 1981–82 recession, and US farm-product prices about 45% from 1929 to 1933.
✗ Reading one episode as a rule. World agricultural prices rose about 69% in real terms in the 2001–07 expansion, but fell slowly in real terms in the other three expansions. Check how many episodes stand behind a verdict before you rely on it.
✗ Mixing up commodity prices, farmland and farm shares. They have different drivers. A rise in crop prices does not automatically lift land values or the shares of companies that carry debt and input costs.
✗ Assuming a fund tracks the price index. Funds that hold futures must roll contracts, and the cost or gain of rolling can make their returns differ from the commodity price. Read how a fund is built before you compare it with a price chart.
How to Access Agriculture as an Investor
📊
Broad Agriculture Futures Funds
Funds holding a basket of crop futures such as grains, oilseeds and sugar. Diversified across crops, but returns depend on contract rolling, so they can differ from the spot price.
Easy access 🌽
Single-Crop Futures Funds
Funds focused on one crop such as wheat, corn or soybeans. Sharper exposure to a single harvest, and sharper swings. Better suited to short-term views than to a core holding.
Complex 🏭
Agribusiness Shares
Seed, fertiliser, equipment and food-processing companies. Their performance depends on margins, debt and demand, not only on crop prices, and this page's verdicts do not apply to them directly.
Medium complexity 🚜
Farmland
Listed farmland companies or direct ownership. Earns rent as well as price changes, but is illiquid and tied to local conditions and interest rates. Not measured by this page's verdicts.
Complex 🌍
Broad Commodity Funds
Funds with an agriculture weighting alongside energy and metals. Diversified, with built-in roll management, but agriculture is only part of the return.

Key Takeaways
- → Weather and war tend to beat the cycle. Food demand is steady, so supply shocks usually move farm prices more than expansions or recessions do. That is why most verdicts here are Neutral or Mixed.
- → The evidence is thin in most conditions. Deflation and depression rest on a single episode each, and wartime and high inflation on one clear rise in three. The evidence label on each verdict says how much it can bear.
- → Spikes often come before the market condition is recognised. The 1972–73 grain spike mostly preceded the stagflation window, and the 2008 and 2022 peaks arrived early in their crises. Waiting for certainty has often meant buying after the move.
- → Steady demand has not stopped large falls. Real agricultural prices fell about 24% in 1981–82, and US farm-product prices about 45% in 1929–33. Recession is Mixed, not Positive.
- → Commodity prices, farmland and farm shares are different investments. The verdicts on this page measure commodity prices only, in real terms and price only.
- → Check how a product is built before you compare it with a price chart. Futures-based funds roll contracts, which can make returns differ from the price index.
