Corn Prices Face Headwinds from Supply Optimism & Trade Tensions

93
Corn futures rallied in early April after President Trump’s new tariffs, driven by front-loaded U.S. exports, a weaker dollar, and a tighter domestic supply.

But by mid-April, prices fell as favourable planting conditions in the U.S., easing supply fears in South America, and escalating trade tensions between the U.S. and China.

As of May 4, 40% of the U.S. corn crop was planted, far above the levels from last year (35%) and above the five-year average of 39%. The sharp jump in plantings between 27/April and 4/May has introduced a bearish backdrop with abundant supply.

Higher crop estimates from Brazil and Argentina added pressure, while slowing export sales signalled that much demand had already been met.

TECHNICAL ANALYSIS

Corn futures flashed a bearish death cross on May 1, as the 9-day moving average (MA) crossed below the 21-day MA. Since then, prices have continued their decline at a rapid pace.

The MACD is turning more negative, and the RSI is nearing oversold territory while staying below its 14-day average, signalling mounting bearish pressure and the potential for further near-term downside.

COMMITMENT OF TRADERS AND OPTIONS DATA

For the week ending April 29, Managed Money sharply increased short positions by 17.1% and trimmed long positions by 5.5%, resulting in a 36.8% drop in net longs. The shift signals growing bearish sentiment and reduced confidence in the near-term price outlook.

Despite the April 2 tariffs, implied volatility stayed muted until mid-April, then rose as prices fell. Skew briefly turned negative on April 8. It has since rebounded to its highest-level YTD, even as prices hit new lows, suggesting that traders remain cautious of further price decline.

Past week open interest trends are intriguing. While call OI on the OZCM5 contract (23/May expiry) increased, call OI contracted on the OZCN5 contract (20/June expiry) suggesting near-term hedging on price rebound risks with continued build-up of longer-term bearish positions.

HYPOTHETICAL TRADE SETUP

Given the bleak fundamentals and bearish technical signals, corn prices may see further downside. While a brief, modest technical rebound is possible, it is likely to be short-lived as the underlying fundamentals remain weak, with few catalysts for a meaningful reversal.

To express views on these trends, portfolio managers can use CME Micro Corn Futures to short the near-term July contract (MZCN2025), which expires on June 20. A hypothetical trade setup offering a reward-to-risk ratio of 1.8x is outlined below:
