Quick summaryWhat you should know about corn futures
- ZC is standard Corn futures on CBOT/CME Group. One contract represents 5,000 bushels of corn.
- Corn is quoted in cents per bushel. One cent in ZC is worth $50, while the minimum tick of 1/4 cent is worth $12.50.
- MZC is Micro Corn futures. It represents 500 bushels, has a $2.50 tick value, and is financially settled against the standard contract.
- The main contract months are March, May, July, September and December.
- The price is driven in particular by weather in the Corn Belt, planted area, yield, WASDE, Grain Stocks, exports, ethanol and animal feed.
- Standard ZC is physically deliverable. Speculative traders should have clear rules for rollover and closing before the delivery period.
- Corn isn't just a technical chart. It's a physical crop, stocks and demand market.
Corn is a physical market before it's a chart
For traders, Corn futures can look tidy on screen: one ticker, clear contract months and a tick value that's easy to calculate. But behind ZC lies a physical market for grain, storage, freight, exports, ethanol and feed.
That makes corn different from index futures. In ES and NQ, the news flow is often rates, earnings and macro. In corn, a single weather model, a single USDA report or a single adjustment to yield expectations can move the market fast.
Important note
Best Futures is not an investment adviser, brokerage or commodity broker. This article explains how corn futures work, but it doesn't provide personal investment recommendations.
Futures carry a high level of risk and aren't suitable for everyone. The NFA, the US industry body, warns that futures trading can be highly volatile, and that traders should only use risk capital they can afford to lose.
Corn futures can also be more demanding than they look. The tick value is lower than in several index, gold and energy contracts, but report days and weather markets can still produce large swings. Margin at your broker isn't an indication of how much you should risk.
What is corn futures?
Corn futures are standardised futures contracts on corn. The contract lets you buy or sell exposure to the corn price for a future contract month, at a price determined in the market today.
The most widely used US contract trades on CBOT, the Chicago Board of Trade, which today is part of CME Group. On CME Globex, the standard contract has the ticker ZC.
For a farmer, grain merchant, exporter or ethanol company, the contract can be used for hedging. For an active trader, it's usually about speculating on the price movement. Most speculative traders will never receive physical corn, but the contract is still tied to a deliverable physical market.
That's exactly why corn often behaves differently from purely financial futures. The price is influenced not just by risk appetite and technical levels, but by planted area, yield, stocks, exports, ethanol, animal feed, currency, freight and weather.
Contract specifications for Corn futures
| Parameter | ZC Corn futures |
|---|---|
| Exchange | CBOT / CME Group |
| Globex code | ZC |
| Underlying | Corn |
| Contract size | 5,000 bushels, roughly 127 metric tonnes |
| Price quotation | Cents per bushel |
| Minimum tick | 1/4 cent per bushel |
| Tick value | $12.50 per contract |
| 1 cent move | $50 per contract |
| Contract months | March, May, July, September and December |
| Settlement | Physical delivery |
| Common use | Hedging, directional trading, spreads and commodity exposure |
CME states that one Corn futures contract represents 5,000 bushels, and that the minimum price move is 1/4 cent per bushel. That gives a tick value of $12.50 per standard contract.
For practical risk management, three numbers matter most:
- 5,000 bushels in standard ZC.
- $12.50 per minimum tick.
- $50 per cent per bushel.
How to read the corn price
Corn is quoted in cents per bushel. If ZC trades around 450'0, that means roughly 450 cents per bushel, or $4.50 per bushel.
Grain contracts are often shown with an apostrophe in the price quote. A move from 450'0 to 451'0 is one cent. Intermediate quotes can represent a quarter cent, for example 450'2, 450'4 and 450'6.
The math is simple:
- 1 cent = $0.01 per bushel.
- 5,000 bushels x $0.01 = $50.
- 1/4 cent = $12.50 per contract.
If you buy one ZC contract at 450'0 and the price rises to 460'0, the move is 10 cents. That equals $500 per contract. If the price falls from 450'0 to 440'0, the loss is likewise $500 before commission, fees and any currency effect.
Micro Corn futures: a smaller contract, the same commodity
CME Group also offers Micro Agricultural futures. Micro Corn has the ticker MZC and is 1/10 of the standard contract. That means 500 bushels instead of 5,000.
This makes MZC more practical for smaller accounts, new commodity traders, and traders who want to practise on corn without full ZC exposure. At the same time, you must check liquidity, spread and broker availability. Standard ZC is the main contract.
| Contract | Size | Minimum tick | Tick value | 1 cent | Settlement |
|---|---|---|---|---|---|
| ZC | 5,000 bushels | 1/4 cent | $12.50 | $50 | Physical delivery |
| MZC | 500 bushels | 1/2 cent | $2.50 | $5 | Financially settled |
The most common mistake is confusing tick value with the value of a full cent. In MZC, one tick is worth $2.50, while one full cent is worth roughly $5.
CME describes the Micro Ag contracts as financially settled against the standard contract. That means MZC doesn't carry the same delivery risk as standard ZC, but it still follows the same underlying corn market.
Why corn is an important commodity market
Corn is a key commodity in the US and global agricultural economy. USDA's Economic Research Service describes corn as the dominant US feed grain crop, and points out that it's used widely in animal feed, ethanol, the food industry, sweeteners, starch and exports.
For traders, that means demand doesn't come from a single source. The corn market is influenced by several supply chains at once:
- animal feed for cattle, hogs and poultry
- ethanol and energy-related demand
- food and industrial products
- exports to major importing countries
- competition from Brazil, Argentina, Ukraine and other exporters
- the US dollar and freight costs
Corn is therefore not just an agricultural product. It's also a commodity that links food, energy, currency and global trade.
What drives the corn price?
The corn price is driven by supply and demand, but the most important variables change throughout the year. In spring, the market is often about planting. In summer, it's about weather and pollination. In autumn, it's about harvest, stocks and actual yield.
1. Weather in the Corn Belt
Weather is one of the most visible drivers in corn. Drought, flooding, extreme heat or delayed planting can change yield expectations. The period around pollination is especially important, because heat and dry conditions can have a major impact on yield potential.
2. WASDE
USDA publishes WASDE, the World Agricultural Supply and Demand Estimates, every month. The report updates production, yield, exports, feed use, ethanol use and ending stocks for US and global markets.
WASDE days should be treated as news days. The market doesn't always react sharply every time, but the report carries enough weight to shift direction if the numbers deviate from expectations.
3. Acreage, planting and crop progress
Corn competes with soybeans for US acreage. If farmers plant more corn than expected, the market can price in higher future supply. If acreage comes in lower than expected, that can support prices.
Crop Progress reports track planting, crop condition and harvest through the season. They're often used together with weather models and yield estimates.
4. Grain Stocks
Grain Stocks shows how much corn is in storage. This is a reality check for the market: has consumption been stronger than expected, or is there more corn in the system than the market thought?
5. Exports and global competition
Export data shows global demand for US corn. Strong demand from major importing markets can support prices, while weak exports or tough competition from South America and the Black Sea region can pressure the market.
6. Ethanol and animal feed
Ethanol is a major source of demand for US corn, while animal feed is another key use. That's why energy economics, fuel demand and margins in livestock production can be relevant to the corn price.
7. The dollar and macro
Corn is priced in US dollars. A stronger dollar can make US corn more expensive for foreign buyers, while a weaker dollar can support export competitiveness. The effect varies, but currency is part of the picture.
Seasonal pattern in corn futures
Corn has a clearer seasonal pattern than many financial futures. That doesn't mean the market follows a fixed formula, but it does say something about what traders typically follow at different times of the year.
| Period | The market often follows |
|---|---|
| January to March | South America, exports, winter stocks and planting intentions. |
| March to May | Prospective Plantings, planting progress and acreage choices between corn and soybeans. |
| June to July | Weather market, pollination, drought, heat risk and yield expectations. |
| August | Yield estimates, crop condition and WASDE. |
| September to November | Harvest, stocks, basis and actual production. |
| December | Exports, ending stocks and positioning ahead of the next season. |
The seasonal pattern isn't a buy or sell signal on its own. It's a calendar for what the market cares about.
How to analyse the corn market
Good corn analysis should combine commodity data with regular market analysis. Technical analysis can be useful, but it shouldn't stand alone around reports and weather events.
A practical workflow
Start with the calendar: WASDE, Crop Progress, Export Sales, Grain Stocks and Acreage. Then look at contract month, volume, spreads and technical levels. Finally, calculate risk in cents and dollars before deciding on contract size.
1. Check the calendar
You should know whether WASDE, Acreage, Grain Stocks, Export Sales or Crop Progress are coming up before opening a position. This is especially important if you hold positions overnight.
2. Read the supply and demand picture
Follow production, yield, planted area, harvested area, feed use, ethanol use, exports, ending stocks and the stocks-to-use ratio. These are variables that often explain larger moves in ZC.
3. Look at the chart
Use trend, prior high/low, volume, VWAP, range, breakout, pullback and support/resistance. Corn can trend well, but can also become heavily news-driven.
4. Follow spreads
Calendar spreads between contract months can say a lot about stocks, carry, scarcity and the relationship between old crop and new crop. This is advanced for new traders, but worth learning.
5. Calculate the risk
Before entry, you should know your stop distance in cents, the risk in dollars, which contract you're using, and whether Micro Corn is a better fit than standard ZC.
Strategies in Corn futures
Corn can be traded in several ways, but the strategy should fit the market's structure.
Directional trading
Directional trading is most common among active traders. It can be long on bullish weather news, short after a bearish WASDE, or trading breaks through clear technical levels. The challenge is that reports can produce fast gaps.
Swing trading
For many retail traders, corn suits swing trading better than pure scalping. News on weather, exports, crop condition and yield can affect the market over several days.
Calendar spreads
Spreads between July/December or December/March can show whether the market is pricing scarcity, storage costs or expectations for the new crop. This is more professional and requires extra understanding, but it's central to commodity trading.
Hedging
Commercial participants use corn futures to lock in a purchase or sale price. Even though private traders rarely hedge physical corn, it's useful to understand that hedgers are an important part of the market.
Position size and risk
Standard ZC can seem manageable because the tick value is $12.50, but larger moves need to be calculated in cents.
| Move | P&L per ZC contract | P&L per MZC contract |
|---|---|---|
| 1 tick | $12.50 | $2.50 |
| 1 cent | $50 | $5 |
| 5 cents | $250 | $25 |
| 10 cents | $500 | $50 |
| 20 cents | $1,000 | $100 |
| 50 cents | $2,500 | $250 |
Example: You're considering a long ZC position at 470'0 with a stop at 462'0. The stop is 8 cents away. In standard ZC, the risk is 8 x $50 = $400 per contract. In MZC, the same move is roughly $40.
If $400 is too much for your plan, the solution isn't to move the stop closer just to lower the risk. Instead, consider a smaller contract, a better entry, a smaller size, or no trade.
Physical delivery, expiry and rollover
Standard ZC is physically deliverable. For speculative traders, that means the contract should normally be closed or rolled before the delivery process becomes relevant. Always check your broker's rules for First Notice Day, the last trading day and any automatic closing.
Many traders shift activity from an expiring contract to the next, more liquid contract before volume dries up. In agricultural markets, choosing the right contract month is especially important because old crop and new crop don't necessarily trade on the same story.
Old crop and new crop
Old crop refers to existing or previous crop. New crop refers to the coming harvest. The December contract is often central for the new US corn crop. July can trade more on existing stocks and physical scarcity, while December can trade more on acreage, weather and yield for the new season.
Basis and carry
Basis is the difference between the local cash price and the futures price. Carry describes situations where later contracts trade higher than nearby contracts, often because storage and financing carry a cost. Such conditions explain why commodity curves don't always behave like index futures.
Common mistakes in corn futures
- Trading WASDE as if it were an ordinary day.
- Ignoring season and weather in the Corn Belt.
- Using too tight a stop around reports.
- Trading the wrong contract month without understanding old crop and new crop.
- Forgetting that standard ZC is physically deliverable.
- Using ZC when MZC better fits the account size.
- Assuming a lower tick value automatically means low risk.
- Treating corn as a purely technical momentum contract.

Conclusion: corn is a specialised futures market
Corn futures are one of the most established markets within agricultural futures. ZC gives exposure to a physical commodity market where weather, yield, exports, ethanol, animal feed, stocks and USDA reports can matter more than ordinary technical signals.
For futures traders, corn can be interesting because the contract is standardised, liquid and easy to calculate. At the same time, the market requires more preparation than many expect. You need to know which contract month you're trading, what one cent is worth, whether you're near a report date, and how to handle physical delivery and rollover.
For many, the most practical entry point is to start with analysis, a simulator and possibly Micro Corn before considering standard ZC. The important thing isn't finding the "right" opinion on the corn price. The important thing is understanding the market well enough to know when the risk is acceptable.

Frequently asked questions about corn futures
Short answers about ZC, MZC, tick value, WASDE, physical delivery and risk.
Corn futures are standardised futures contracts on corn. The most widely used contract trades on CBOT, part of CME Group, with ticker ZC on CME Globex.
The ticker for standard Corn futures on CME Globex is ZC. Micro Corn futures has the ticker MZC.
One standard ZC contract represents 5,000 bushels of corn, equal to roughly 127 metric tonnes.
The minimum tick is 1/4 cent per bushel. That equals $12.50 per standard ZC contract.
One cent per bushel equals $50 per standard ZC contract. For Micro Corn, one cent equals roughly $5.
Micro Corn futures is CME Group's smaller corn contract with ticker MZC. It is 1/10 of the standard contract, represents 500 bushels, and has a tick value of $2.50.
Yes, standard ZC is physically deliverable. Active traders should therefore know their broker's rules for First Notice Day, the last trading day, rollover and any closing ahead of delivery.
WASDE stands for World Agricultural Supply and Demand Estimates. USDA publishes the report monthly, and it updates production, consumption, exports, stocks and global balances for grains and other commodities.
The key drivers are weather in the Corn Belt, planted area, yield, USDA reports, stocks, exports, ethanol, animal feed, the dollar, and competition from other exporting countries.
Corn futures can be educational, but it isn't a simple beginner product. You should understand contract size, the report calendar, seasonal patterns, physical delivery and position size before trading live.
