What WASDE Days Do to Grain Futures: Intraday Volatility Patterns You Can Plan Around

Nov 17, 2025

By Eunchun Park

When there isn’t a government shutdown that limits reporting activities, the World Agricultural Supply and Demand Estimates (WASDE) report is a once-a-month shock that does more than nudge the average price. On release days, the intraday volatility pattern—its level across the session, its midday spike, and how quickly that spike fades—differs from ordinary days in ways that traders, merchandisers, and risk managers can plan around. A recent research article evaluated the impact of the WASDE report on commodity futures markets’ volatility (Lee and Park, 2024). Here we translate this research into practical guidance for traders when a WASDE report is released.

Most trading plans benchmark a point estimate—an expected move or a single daily volatility number. But markets trade through time. On WASDE days, volatility is comparatively calm into late morning, jumps right after the 11:00 a.m. Central Time (CT) release, and then eases within about an hour. Treating the day like any other misses the timing and the intraday pattern that drives fills, slippage, and margin exposure.

We study corn and soybean futures from January 2013 through April 2023, focusing on regular trading hours (8:30 a.m. to 2:00 p.m. CT) and explicitly comparing three kinds of sessions: the release day itself, the day before, and the day after. Instead of averaging volatility across the whole day, we recover the intraday volatility curve—how volatility evolves minute by minute.

Video: Winter Canola Trial in Mississippi | Can It Work for Double Cropping? | Pioneer Agronomy

Can winter canola open new opportunities for growers in the Mid-South? In this agronomy update from Noxubee County, Mississippi, Pioneer agronomist Gus Eifling shares an early look at a first-year winter canola trial and what farmers are learning from the field.

Planted in late October on 30-inch rows, the crop is now entering the bloom stage and progressing quickly. In this video, we walk through current field conditions, fertility management, and how timing could make this crop a valuable option for double-cropping soybeans or cotton.

If harvest timing lines up with early May, growers may be able to transition directly into another crop during ideal planting windows. Ongoing field trials will help determine whether canola could become a viable rotational option for the region.

Watch for:

How winter canola is performing in its first season in this Mississippi field

Why growers chose 30-inch rows for this trial

What the crop looks like as it moves from bolting into bloom

Fertility strategy, including nitrogen and sulfur applications

How canola harvest timing could enable double-cropping with soybeans or cotton

Upcoming trials comparing soybeans after canola vs. traditional planting

As more growers look for ways to maximize acres and diversify rotations, experiments like this help determine what new crops might fit into existing systems.
