Global Corn Inventories Tighten in 2026/27, U.S. Soybean Inventories Miss Expectations

Overview

This report interprets USDA's first 2026/27 WASDE supply-demand forecasts. The key conclusion is that, for corn, U.S. inventories are slightly above expectations but global inventories are materially below consensus, creating a relatively constructive globally tight balance. For soybeans, U.S. new-crop inventories are below consensus and the tightening is demand-driven, making the signal even more favorable. For Latin American agricultural stocks, improved price expectations support farmer income, and SLC Agricola benefits most directly because of its higher soybean exposure.

Core views

The report's core views are: first, global corn inventories are tight, with 2026/27 global ending stocks below consensus and near multi-year lows; second, U.S. corn inventories are above Morgan Stanley's forecast and slightly above consensus, mainly because of supply-side rather than demand-side factors; third, U.S. soybean inventories are materially below consensus, and the tightening is driven by stronger crush and export demand; fourth, the tighter supply-demand balance supports higher corn and soybean prices in 2026/27; fifth, from an equity perspective, Latin American agricultural stocks benefit, but a stronger BRL, higher input costs, and financing pressure may limit margin expansion.

Analysis framework

The report uses the USDA WASDE supply-demand balance sheet, compares USDA's 2026/27 forecasts with Bloomberg Consensus, Morgan Stanley's own forecasts, and historical stock-to-use ratios, and then maps the results to agricultural commodity prices, Latin American farmer profitability, and listed company exposures. The equity impact analysis focuses on crop prices, currency, input costs, and company business mix.

Methodology notes

• Agricultural supply-demand analysisUSDA WASDE balance sheet

  supply-demand balance sheet

  Uses production, demand, ending stocks, stock-to-use ratio, and export assumptions to judge whether the corn and soybean markets are tight or loose.

• Inventory cycle analysisstock-to-use ratio

  stock-to-use ratio

  The stock-to-use ratio measures the buffer of inventories relative to demand; a lower ratio usually signals tighter supply and stronger price support.

• Equity impact mappingcommodity-to-equity exposure mapping

  commodity price transmission to agricultural equity earnings

  Maps changes in corn and soybean price expectations into revenue and profit for Latin American agricultural companies, while also considering BRL moves, input costs, and differences in crop exposure.

• Valuation methodDCF methodology

  discounted cash flow valuation

  The report discloses that SLC Agricola's valuation is based on DCF, assuming a 14.1% WACC and a 3.0% terminal growth rate; some Adecoagro scenarios also incorporate Profertil EBITDA, urea prices, natural gas costs, and sugar-ethanol business valuation assumptions.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Corn

  Core coverage commodity

  Strengths

  Global 2026/27 ending stocks are below consensus, inventories are tight, and prices have support.

  Weaknesses

  U.S. inventories are slightly above consensus, and the surprise mainly comes from supply-side factors, making the bullish signal weaker than for soybeans.

  Comparison

  Compared with soybeans, corn shows a globally tight but more mixed U.S. picture.

  Risks

  Higher-than-expected U.S. supply, weaker export demand, softer feed demand, or improved weather could pressure prices.

• Soybeans

  Core coverage commodity

  Strengths

  U.S. 2026/27 ending stocks are materially below consensus, with tightening driven by stronger crush and export demand, making the signal more bullish.

  Weaknesses

  Global supply remains relatively abundant; USDA's global stocks are above Morgan Stanley's forecast, and the assumption for Brazil's 2026/27 production may be too optimistic.

  Comparison

  Compared with corn, the U.S. soybean inventory shock is clearer, and the earnings linkage to Latin American farmers and SLC Agricola is more direct.

  Risks

  A record harvest in Brazil, slower demand, weaker-than-expected exports, or financing pressure could affect planting and selling pace.

• SLC Agricola S.A. (SLCE3.SA)

  Most direct beneficiary stock

  Strengths

  Higher soybean exposure makes it a more direct beneficiary of soybean price gains and inventory-tightening signals.

  Weaknesses

  BRL appreciation and higher input costs may limit earnings upside.

  Comparison

  Compared with Adecoagro, SLC Agricola has a higher direct sensitivity to soybean price changes.

  Risks

  Rising costs in Brazil, weather disruptions, crop failure, weaker feed demand, and adverse FX moves.

• ADECOAGRO S.A. (AGRO.N)

  Related beneficiary stock

  Strengths

  Has soybean and corn exposure in Argentina, along with sugar and ethanol and Profertil businesses.

  Weaknesses

  Soybean and corn contribute a smaller share of total earnings, so the commodity price pass-through is less direct than for SLC Agricola.

  Comparison

  Compared with SLC Agricola, Adecoagro's business is more diversified and has less leverage to a single crop price increase.

  Risks

  Further macro deterioration in Argentina, lower ethanol prices due to Brazilian fuel policy, and higher sugar production costs in Brazil.

Impact & implications

Tighter corn and soybean supply-demand signals support higher agricultural commodity prices in 2026/27 and provide a positive backdrop for Latin American agricultural stocks. The soybean-related tailwind is concentrated in U.S. inventory tightening and demand improvement, which is especially supportive for SLC Agricola because of its higher soybean exposure. Adecoagro also benefits from exposure to Argentine soybeans and corn, but these activities account for a smaller share of overall results. Overall, the commodity tailwind is offset by BRL appreciation, input costs, and financing pressure in Brazil's agricultural sector, so the report does not move to a more positive rating.

Risks

• BRL appreciation may offset profit improvement from higher agricultural commodity prices.
• Higher input costs may compress profit margins for Latin American agricultural companies.
• If Brazil's 2026/27 soybean production reaches or exceeds USDA's optimistic assumption, global supply tightness could ease.
• If U.S. or global export demand falls short of USDA assumptions, the inventory-tightening logic could weaken.
• Weather disruptions may push prices higher, but they can also cause crop failures and hurt company output.
• Weaker feed demand could pressure grain prices.
• Morgan Stanley may have potential conflicts of interest through investment banking, non-investment banking, or market-making activities with some covered companies, so investors should make their own judgment based on disclosures.

What to watch

• The next USDA PSD release on 2026-06-11.
• Whether U.S. soybean and corn exports validate USDA's demand assumptions.
• The impact of planting progress, crop conditions, and weather changes on yield risk for the new crop.
• Input costs, financing conditions, and crop affordability ahead of the 2026/27 soybean planting season in Brazil.
• BRL exchange-rate trends and their effect on Latin American agricultural stock margins.
• Changes in corn and soybean stock-to-use ratios versus historical averages.
