The International Food Policy Research Institute has published an analysis that links proposed U.S. tariff scenarios to measurable shifts in agricultural trade flows across the Western Hemisphere, framing the policy debate in terms that input manufacturers, exporters, and grower cooperatives can translate into margin and basis planning.

IFPRI, a Washington, D.C.-based research center established in 1975, posted the assessment under the title "Impact of proposed U.S. tariffs on agricultural trade flows in the Western Hemisphere." The piece joins a body of IFPRI work that quantifies how border measures — including retaliatory duties — translate into farm-gate prices, port basis (the cash-market difference between local delivery and a futures reference price), and the relative competitiveness of competing exporters.

What does the analysis cover?

The Western Hemisphere geography matters because the United States runs deeply integrated agricultural supply chains with two partner groups: the United States-Mexico-Canada Agreement (USMCA) economies on its northern and southern land borders, and the MERCOSUR bloc (Argentina, Brazil, Paraguay, Uruguay) plus Chile and Peru along South America's coasts.

A duty regime that touches one set of partners reverberates into the other through substitution effects, particularly in soybeans, corn, beef, pork, dairy, fruits, and vegetables.

For corn and soybean growers in the Midwest, the practical question is basis: if Mexico or China-bound flows contract, the local cash price relative to the Chicago Board of Trade futures benchmark erodes and elevator (grain-handling facility) margins compress.

For specialty crop and fresh-produce operations that move north into the United States from Mexico and Central America in winter, the question is reciprocal duty exposure on the export side and the cost of any imported inputs that pass through tariffed supply chains.

Why IFPRI's framing matters for practitioners

IFPRI's analytical tradition treats tariff schedules as data inputs into computable general equilibrium (CGE) models — economy-wide simulations that estimate how price changes in one sector ripple through output, consumption, and trade.

The institution has consistently published peer-reviewed estimates on how trade frictions affect food prices in net-importing developing countries, and its Western Hemisphere tariff work sits within that lineage.

For growers and agribusinesses reading the assessment, the value lies less in any single forecast than in the structure of the question: how does a duty at one port change the marginal buyer for a shipload of soybeans or a truckload of avocados?

What does the policy timeline imply?

The phrase "proposed" signals that the analysis treats duties as conditional scenarios rather than enacted law.

That distinction matters for procurement officers at cooperatives, who must hedge (lock in forward contracts to manage price risk) against implementation risk without paying the carrying cost of certainty.

The same framing matters for input manufacturers — fertilizer, crop protection, seed — whose cross-border sourcing decisions turn on whether a tariff becomes operative and whether a partner government retaliates in the agricultural lane.

A separate condition to read is the difference between first-round tariff effects and the retaliation that historically follows.

IFPRI's body of work on the 2018-2019 U.S.-China tariff exchange, for example, documented soybean basis shifts of several dollars per bushel at the U.S. Gulf and rerouting of Brazilian and Argentine exports through Pacific terminals.

Any Western Hemisphere tariff analysis that omits the retaliation pathway understates the basis and freight story.

What should growers watch next?

The practical deliverable from the IFPRI piece is a baseline against which industry-survey data can be tested.

Cooperatives running route economics for the next marketing year, and growers watching new-crop basis boards at local terminals, will measure the IFPRI estimates against their own delivered-cost numbers.

The forward-looking question is whether the policy proposal advances, stalls, or modifies into something narrower, because the analytical answer changes with the schedule that policy makers ultimately impose.
