March WASDE: USDA Holds
All Three Commodities Unchanged

USDA reported corn carryout (ending stocks) unchanged from February at 2.130 billion bushels. The pre-release trade consensus averaged 2.155 billion bushels — the surveyed range of 2.077–2.428 billion bushels reflected genuine uncertainty, with the market leaning toward a modest downward revision given export commitments running 31% above year-ago pace. The USDA figure came in 25 million bushels below the consensus average — a modestly bullish surprise relative to pre-report positioning.

With carryout at 2.130 billion bushels against total use of approximately 5.8 billion bushels, days of use stand near 134 days — a comfortable reading in the moderate range. The market's bullish export narrative has not yet translated into a USDA balance sheet adjustment, which is the core tension heading into April.

No U.S. supply or demand line was revised. USDA held corn exports, feed and residual use, and ethanol unchanged despite export commitments running well ahead of the prior year. Globally, foreign corn production was raised, led by increases for Ukraine and Brazil's first crop while Argentina was trimmed on February dryness. Global corn carryout rose 3.8 million metric tons to 292.8 million — a bearish global backdrop that supports USDA's reluctance to tighten the U.S. balance sheet this month.

An unchanged U.S. carryout against a market positioned for a bullish cut creates a mixed signal for basis. Illinois River corridor corn basis, which had been firming on export commitment strength, faces near-term softening pressure. Watch for barge basis to ease 3–6 cents under May futures at the Illinois River corridor if this report removes urgency for merchandisers to bid aggressively for nearby bushels. Gulf export basis may hold better than interior if actual export shipment pace remains strong through March, but an unchanged USDA figure removes the catalyst for a basis rally.

With an unchanged carryout and a rising global stocks figure, the carry structure is unlikely to have tightened materially on this release. Operators should check the current July/December corn spread against commercial storage cost of $0.04–$0.05 per bushel per month to assess whether the market is compensating for holding new-crop inventory.

USDA reported soybean carryout at 350 million bushels, unchanged from February. The pre-release trade consensus averaged 343 million bushels (range: 320–365 million bushels). The USDA figure came in 7 million bushels above the consensus average — a modestly bearish surprise for a market already contending with slumping export sales and a price-competitive Brazilian harvest.

With total soybean use held steady from February (approximately 3.74 billion bushels), carryout of 350 million bushels equates to roughly 34 days of use — at the upper end of the moderate range (20–35 days), nearing comfortable territory. This reflects a meaningful loosening of the soybean balance sheet over the course of the 2025/26 marketing year.

The only U.S. changes this month were offsetting: imports were raised 5 million bushels on trade data and crush was raised 5 million bushels on stronger soybean meal domestic demand — these two revisions canceled out with no net effect on carryout. Exports were left unchanged despite an 18% year-over-year deficit in sales pace. Globally, soybean carryout was trimmed a modest 0.2 million metric tons. Soybean oil for biofuel was cut 800 million pounds to 14.0 billion — a bearish signal for soy oil values that operators processing or storing beans should note.

A carryout figure 7 million bushels above consensus, combined with no export acknowledgment and a neutral crush adjustment, is negative for basis. Central Corn Belt interior elevator soybean basis had been supported by crush plant demand on strong soybean meal margins — that support may narrow but is unlikely to evaporate entirely given confirmed crush strength. Gulf soybean export basis faces greater pressure. Watch for Gulf export basis to soften 5–8 cents under May futures over the next two weeks.

With an unchanged and above-consensus carryout, the market has reduced incentive to narrow the carry. Operators holding old-crop soybeans into late spring should verify whether the current May/July spread covers storage and interest before committing to hold beyond May delivery.

USDA reported U.S. wheat carryout unchanged from February at 931 million bushels. The pre-release trade consensus averaged 923 million bushels. The USDA figure came in 8 million bushels above consensus — the survey correctly anticipated minimal U.S. changes ahead of the March 1 Grain Stocks report, representing a neutral outcome with no meaningful bullish or bearish surprise.

With no revisions to supply or use, wheat days of use are unchanged from February. All-wheat carryout of 931 million bushels against total use of approximately 1.87 billion bushels implies roughly 180 days of use — reflecting the large but structurally normal wheat pipeline. Global wheat ending stocks at 277.0 million metric tons remain a 5-year high, even after a 0.6 million ton reduction this month.

No U.S. line items changed. Globally, the modest reduction in world wheat ending stocks was driven by a 1.0 million ton cut to Australian production, now pegged at 36.0 million tons, partially offset by higher output for Ukraine and Kazakhstan. Argentina's exports were raised a notable 1.5 million metric tons to a record 19.5 million — confirming that Argentina remains the world's lowest-priced major exporter, a structural headwind for U.S. export competitiveness.

A neutral U.S. carryout outcome provides no fundamental catalyst to move wheat basis in either direction. The current rally in wheat prices is being driven by winter wheat drought concerns in the Southern Plains, not old-crop fundamentals. Kansas City HRW cash market basis may hold steady to slightly firm near May futures as drought premium supports producer selling resistance, but the WASDE provides no supply-side justification for basis appreciation. SRW basis at Chicago delivery points and Gulf HRW export basis should remain range-bound until the April WASDE or clearer signals from winter wheat condition ratings.
