Tariff Deadline has strong Impact on Markets

Tariff Deadline has strong Impact on Markets

Heavy rainfall reduced drought in the U.S. Midwest

On this week’s Ag Commodity Corner+ Podcast with Farms.com Risk Management Commodity Strategist Abhinesh Gopal, for the week of July 28 to August 1, 2025, the episode centered on the August 1 U.S. tariff deadline and its wide-ranging market effects.

Grain markets saw losses this week, showing “a lot of red on the screen,” as weather fears faded. Canola remains supported by weather challenges, but traded lower during the week.

Meanwhile, the livestock sector continued strong, with cattle leading for another week.

The stock markets, which had hit record highs, saw corrections by week’s end. Tariff updates were a key market driver. The U.S. confirmed trade agreements with key partners like the EU and South Korea, while others like Canada, Mexico, India, and Australia remained pending.

Notably, tariffs on Canadian goods outside the USMCA increased from 25% to 35%, while Mexico received another 90-day tariff pause.

President Trump also announced 10–50% tariffs on various partners/sectors, with a special 40% transshipment tariff targeting goods rerouted through third countries. Talks with China in Stockholm hinted at an extension to their tariff pause, set to expire August 12.

Weather-wise, heavy rainfall reduced drought in the U.S. Midwest to just 8.5%, down from about 30% in June, removing much of the grain market’s weather risk. A derecho event earlier in the week turned out to be minor.

In financial updates, The U.S. Federal Reserve left rates unchanged, but poor jobs data raised expectations for a September rate cut. Bank of Canada held interest rates at 2.75%, with underlying inflation believed to be 2.5%.

Wheat Yields in USA and China Threatened by Heat Waves Breaking Enzymes

Video: Wheat Yields in USA and China Threatened by Heat Waves Breaking Enzymes

A new peer reviewed study looks at the generally unrecognized risk of heat waves surpassing the threshold for enzyme damage in wheat.

Most studies that look at crop failure in the main food growing regions (breadbaskets of the planet) look at temperatures and droughts in the historical records to assess present day risk. Since the climate system has changed, these historical based risk analysis studies underestimate the present-day risks.

What this new research study does is generate an ensemble of plausible scenarios for the present climate in terms of temperatures and precipitation, and looks at how many of these plausible scenarios exceed the enzyme-breaking temperature of 32.8 C for wheat, and exceed the high stress yield reducing temperature of 27.8 C for wheat. Also, the study considers the possibility of a compounded failure with heat waves in both regions simultaneously, this greatly reducing global wheat supply and causing severe shortages.

Results show that the likelihood (risk) of wheat crop failure with a one-in-hundred likelihood in 1981 has in today’s climate become increased by 16x in the USA winter wheat crop (to one-in-six) and by 6x in northeast China (to one-in-sixteen).

The risks determined in this new paper are much greater than that obtained in previous work that determines risk by analyzing historical climate patterns.

Clearly, since the climate system is rapidly changing, we cannot assume stationarity and calculate risk probabilities like we did traditionally before.

We are essentially on a new planet, with a new climate regime, and have to understand that everything is different now.
