As Demand For Corn Grows, New Key Data Points To Watch

Over the past year, and even more so in the last few months we’ve seen a significant change in corn market fundamentals. From a year ago, the corn ending stocks to usage has gone from 13.75% to 7.4%, one of the lowest on record. Demand for U.S. grains has been at historic levels during 2021. U.S. weather during the last few key production months has featured hot and dry weather over significant parts of the growing region.

All of this has driven significant volatility. But how does that volatility stack up to recent years and what can volatility tell us about risk and risk management strategies? Many of those answers can be found in the new CVOL Index that CME started publishing in February 2021.

If we look at the CVL Index, which measures corn volatility, we can see it reached a high of 57 recently, more than double compared to 2019 and early 2020 levels. The chart below shows CVL Index over the last two years.  The dotted line is price and the solid line is the CVL Index.

As a grain participant, the CVL Index can help visualize how implied volatility is reacting to market conditions which directly impacts the price of corn options. The index covers an array of strikes and maturities, allowing for a baseline on what is happening in the options market. It is part of the larger suite of new CVOL indexes, which capture constant 30-day implied volatility and clarify it through a unique prism that generates new sets of robust volatility indices. Thirty-day implied volatility is a liquid and sensitive part of the volatility surface and is closely watched by market participants. Traditionally it has been difficult to easily see 30-day implied volatility as options decay or drift towards maturity.

Market Sentiment Shown Through Options

CME Group built CVOL to easily separate and recombine parts of the surface related to calls and puts to deliver Upward Variance from out of the money (OTM) calls, called Up Var, and Downward Variance from OTM puts called Down Var. These variance tools provide insight into possible asymmetry in the implied volatility curve by isolating just the call or put wing of the volatility surface.

Looking at UPVar in corn over time, you can see a wide range of values. This is showing how market participants have reacted to price and what seasonal factors are at play. The UP Var index uses an array of out-of-the-money calls to create a holistic view of upside sentiment, you can see how call implied volatility peaked going into the June 30 Acreage report. Market participants can use this information as a general guide to understand how call options are changing in terms of the volatility surface and then use the data to optimize hedging and risk/reward profiles.

Positive Skew

The Grain & Oilseed complex typically exhibits a positive skew, indicating that market participants expect price to exhibit higher velocity as the price of corn increases. The level of skew can change quite dramatically in Ag markets. The chart below shows corn skew increasing from 8% to almost 15% in the month of June when corn prices declined significantly. Skew helps show shifts in demand and expectations looking at the upside relative to the downside.

Traders are always seeking the most comprehensive data to help them prepare for the unexpected. In a market defined by high global demand and uncertain fundamentals, CVL is another tool they can look to navigate corn markets.
