Set Your Focus On $8-10 / bu Corn Between 2021-2023

March 10, 2021

The outlook for corn is very positive given improved supply and demand fundamentals as well as supportive macroeconomic backdrop.

  • Corn is due for a sharp rally, and we will likely see $8-10 per bushel between 2021-2023
  • Corn has been in a deep bear market since 2013... Eight long years. Core supply and demand fundamentals are now improving.
  • Global commodity prices have started to break out of a multi-year range. Drivers include:
    1. the demand recovery as the pandemic moderates
    2. supply disruptions due to shortages, and
    3. fiscal stimulus injected by governments worldwide. A rising tide lifts all boats.
  • Legendary commodity investor Jim Rogers has often said that major commodity cycles tend to be about every 20 years. He predicted the last great commodities bull market that started in 1999... 1999 + 20 = 2019. Is it time to get long-term bullish?

A Rising Tide Lifts All Boats

Commodity cycles follow the old adage “history rhymes, but it does not repeat”. We always have had commodity cycles, and we always will. The driving factors for each cycle tend to differ.

The last corn bull market was driven in part by the Renewable Fuel Standard (“RFS”, also known as the ethanol mandate) and a growing middle-class in China. Common cycle drivers in the past have included weather fluctuations, wars, embargoes, tariffs, inflation, etc.

The current cycle’s drivers include:

  • New fiscal stimulus and meaningful increase in money supply
  • Labor and farmhand shortages due to travel restrictions
  • Growing middle class India, Indonesia, Vietnam, Sub-Sahara Africa and other new-era emerging markets

Last week the United Nations' Food & Agriculture Organization (FAO) released its March 2021 report. The FAO tracks a global basket of food staples including sugar, dairy, vegetable oils, cereals and meat — this index rose 2.4% in February, reaching its highest level since July 2014 (ninth consecutive monthly increase).

The FAO’s food index was stuck in a range of plus or minus 10% since 2015, and it began to break out of the range starting in 4Q 2020. It is now ~20% higher than the trailing five-year range, with the bulk of the increase occurring over the last nine months. The report had a common theme for most of the categories: shrinking supply and growing global demand.

Takeaway: The FAO food price index was stuck in a range for five years, and recently it started to break out (red and yellow lines lines).

There is a modest correlation and common trend among agriculture commodities long-term, as well as broader industrial metals and energy. During the initial onset of the pandemic commodities took a hit as markets re-calibrated for lower growth expectations.

We saw oil prices go negative for the first time ever, and a flight to safety and bonds. Commodities bottomed and began their strong recovery when governments around the world announced their large fiscal stimulus plans.

The fiscal stimulus is impacting prices and demand. The transmission of this stimulus is different than prior economic recovery measures that followed the Financial Crisis - this stimulus is cash given directly to people and businesses to spend immediately.

Money supply (as measured by the Federal Reserve’s M3) is 24% higher than it was prior to the stimulus. Congress is about to pass legislation to distribute another $1.9 trillion, which is an additional 10% growth to the money supply.

Asset Prices Have Surged After Fiscal Stimulus

These are some big moves by historical standards. Reported consumer price inflation is +1%? Hmm... that’s a head-scratcher.


We should start to see these large price moves work their way into consumer and producer prices over coming months. Price increases often have a 6-12 month lag given a variety of factors, including:

  • many existing contractual agreements adjust pricing quarterly or annually and need time to adjust
  • transit times
  • "wait and see" approach by sellers to confirm the higher costs are sticky

Core Corn Fundamentals Are Improving

WASDE Corn Fundamentals Are Improving

The USDA’s 2020/21 corn forecast (World Agricultural Supply and Demand Estimates, “WASDE”) has gradually changed its tune since the initial forecast in July 2020. It now paints a picture of a more constrained supply and demand environment than originally anticipated. March 2021 WASDE report link

WASDE lowered its ending stocks projection by 43% to 1.5bn bu from 2.6bn bu, and ending stocks-to-use ratio from 18% to 10%. Most of the revision is due to increased exports (0.5bn bu) and decreased production (0.8bn bu) - offset by lower domestic feed consumption (0.2bn bu).

Prices tend to become more volatile and susceptible to sharp moves to the upside when the stocks-to-use ratio is in the single-digit range. There is less padding for any unforeseen reductions in yield from weather surprises.

Takeaway: Over the long-term trend yield (dark line) increases, driven by technology, machinery and seed improvements. WASDE projects 2020/21 yield of 172 bu/acre (about 2% lower than trend yield at 176 bu/acre). WASDE began its forecast at 178.5 bu/acre in July 2020 and gradually revised it down to 172 bu/acre.

Long-term corn yield deviation relative to expected trend yield

Takeaway: Reported yield tends to be volatile relative to trend yield. The chart above shows the percentage variance of reported yield relative to the expected trend yield. About a third of time reported yield is at least 5% better than trend yield, and about a quarter of the time reported yield is at least 5% worse than trend yield. For reference, the recent 2012 drought caused the reported yield to be 22% worse than the trend yield.

There is a one-in-four chance that we will see the stocks-to-use ratio drop to single digits, a level that typically coincides with sharp price moves to the upside. There is a 1-in-12 chance that reported yield is 10% worse than trend yield, which would lower the stocks-to-use ratio to about 1% (all else equal).

There are a couple of items that we learned from the 2012 drought:

  • Lower yields may hurt farmer sentiment short term, but crop insurance and higher crop prices ultimately helped farmers medium-term more than the damage done by lower yields. Crop insurance enabled farmers to smooth out the volatility caused by weather
  • Higher grain prices led to some demand reduction (culling of herds, etc)

The key point here is we could easily see $8-10 / bu corn over the next few years... there is not a lot of wiggle room given current trends and unpredictable variables such as weather. Even if we get through this year with a decent yield and moderate prices, there will likely be continued pressure on global stocks in the coming years.

We have just exited an eight-year bear market in corn that moderated risk-taking and speculative planting. More importantly, it slowed the addition of new acreage in other parts of the world that did not produce corn in the past.

Takeaway: Stocks-to-Use ratio long-term median level is 15%, and when it dips below 10% it typically corresponds with rising corn price.

Equipment Manufacturers Are Positive

John Deere reported strong first-quarter 2021 earnings on February 19, beating analyst estimates. On the earnings call management noted "Ag fundamentals improved significantly throughout the first quarter and the improved sentiment is reflected in the most recent status of our order books and early order programs".

The outlook for fiscal year 2021 is very optimistic:

  • Large ag equipment sales in US & Canada equipment will be up between 15% and 20%
    • Crop Care early order program that ended in October was up double digits
    • Combine early order program ending in January was up double digits, outpacing Crop Care
  • Large tractor order book now extends through most of the year, so Deere is increasing production rates
  • Small ag and turf equipment in US & Canada are expected to be up 5%
  • European ag market is forecast to grow about 5%, with a solid order book extending through most of 2021
  • South American ag is forecast to grow about 10%. Deere noted that private financing conditions are improving in South America, providing better credit availability to farmers
  • Ag sales in Asia are expected to be down slightly

Ryan Campbell, Deere CFO, noted “We've seen underlying fundamentals continue to improve since the last quarter. Higher commodity prices and improved market access have boosted sentiment in ag markets and are reflected in the results of our early order programs and order books. In addition, we've seen further strength and demand for compact utility tractors and turf equipment, as consumers continue to focus on home and landscape projects.”

Used Tractor & Combine Auction Sales Prices Are Strengthening

“The (used equipment auction price) trend has been up recently since commodities jumped up over the last few months. Equipment prices have jumped up too. Trends are definitely stronger,” said Bill Sullivan, of Sullivan Auctioneers in Hamilton, Illinois. “I would say many prices have gone back to the 2012 peak.” Auctions across the US are reporting higher prices for used tractors, combines, sprayers and planters across the board for all major manufacturers.


Agriculture commodities always have been and always will be in demand... We all need to eat. Agriculture demand has weathered countless financial and political storms since civilization began. There is no telling of what will happen with increased money printing — but there will always be demand for grain.

Historically speaking agriculture and land have been safe investments that weather political and monetary volatility. In addition, the long-term cycles can be very powerful once they start. Typically prices increase by 3-4x during a long-term bull market, which suggests even more upside beyond $8-10 / bu corn.
