WASDE Mar 2026 – Specs Long Despite Comfortable Supply
Mar 10, 2026
Every month, the USDA updates its global crop supply estimates — and this month, corn and soybean specs are holding their largest net long positions in two years, even as US stockpiles look comfortable.
Executive Summary
The March WASDE reveals a notable divergence between US supply fundamentals and speculative positioning across major grains. Corn specs are net long at the 89th percentile (2-year) despite a US stocks-to-use ratio of 12.9% — well above the 5-year average of 9.9%. The positioning may reflect world supply conditions, where global S/U at 23.7% sits below the 26.6% average.

Global Backdrop
The FAO Food Price Index rose 1.3% month-over-month to 127.8 in January, with a 5.4% gain over three months indicating sustained upward pressure on global food costs. Fertilizer input costs continue trending higher, with nitrogen-based fertilizer prices up 1.8% over the past three months — providing a supportive backdrop for crop pricing even as US supply conditions remain comfortable.
Corn: World Tightening vs US Balance
US corn stocks-to-use of 12.9% sits well above the 5-year average of 9.9%, representing a 2.6 percentage point increase from last year's already comfortable 10.3%. Production of 17.02 billion bushels with exports of 3.3 billion creates a balanced domestic picture. The WASDE has held steady through the campaign with no revisions since February.
However, global supply conditions tell a different story. World S/U of 23.7% sits below the 26.6% five-year average, down 1.0 percentage point year-over-year. This creates a 10.8 percentage point divergence between loose US conditions and tighter global supply.
Specs are positioned net long 257,781 contracts — the 89th percentile over 2 years (71st over 10 years). The weekly addition of 167,722 contracts suggests recent momentum into the positioning. The corn story this month is world supply tightening driving spec demand despite a balanced US balance sheet.
Soybeans: Extreme Positioning into Divergent Supply Signals
US soybean S/U of 8.2% sits above the 5-year average of 6.7%, up from last year's 7.3% — indicating a comfortable domestic supply picture. Production of 4.26 billion bushels supports exports of 1.575 billion bushels with adequate carryover. Like corn, the WASDE has remained unchanged through the campaign.
The global picture diverges sharply. World S/U of 30.4% exceeds the 28.9% average despite a 0.4 percentage point decline year-over-year. This creates a massive 22.2 percentage point gap between US and world supply conditions — the largest divergence among major crops.
Despite comfortable US fundamentals, specs hold 230,268 contracts net long — the 97th percentile over 2 years (93rd over 10 years). This represents extreme positioning across both timeframes. The soybean narrative reflects specs responding to factors beyond US supply abundance, potentially South American crop concerns or export demand shifts.
Soybean Complex: Products Follow the Bean
Soybean meal and oil positioning aligns with the underlying bean positioning. Meal specs are net long at the 96th percentile over 2 years (77th over 10 years) with a weekly increase of 26,423 contracts. Oil positioning is even more extreme at the 99th percentile over 2 years (87th over 10 years), adding 28,562 contracts weekly. The crush products confirm the broad soybean complex is seeing significant spec demand despite comfortable US supply fundamentals.
Wheat: Specs Short Despite Global Tightening
US wheat presents the inverse of corn and soybeans. The combined S/U ratio of 45.9% far exceeds the 37.5% five-year average — indicating abundant domestic supply. Year-over-year S/U increased 2.5 percentage points from an already loose 43.4%. Production of 1.98 billion bushels easily covers exports of 900 million bushels.
Global wheat supply at 37.1% S/U sits slightly below the 38.1% average, up 1.3 percentage points year-over-year. The 8.8 percentage point gap shows US supply is significantly looser than world conditions.
Specs are positioned net short 29,165 contracts — the 77th percentile for short positions over 2 years (45th over 10 years). However, HRW wheat shows net long positioning of 6,048 contracts at the 99th percentile over 2 years, suggesting class-specific dynamics within the wheat complex. Wheat positioning reflects abundant US supply overwhelming any global tightening considerations.
Cotton: Modest Longs into Comfortable Supply
US cotton S/U of 32.4% exceeds the 26.4% five-year average by 6 percentage points, up from last year's 29.4%. Production of 13.9 million bales far outstrips the modest 12 million bale export program. World supply is even more abundant at 64.4% S/U, above the 62.6% average.
Despite the 32.0 percentage point divergence between US and world supply (the largest gap among all commodities), both regions show comfortable conditions. Specs hold a modest net short position of 21,031 contracts — the 73rd percentile for shorts over 2 years (18th over 10 years). Cotton positioning reflects the reality of abundant global fiber supplies.
Softs & Livestock: Mixed Positioning Patterns
Sugar specs maintain an extreme net short position of 208,755 contracts at the 5th percentile over 2 years (1st over 10 years), though the weekly addition of 36,279 contracts suggests some short covering. Coffee shows minimal net long positioning at just 14,989 contracts. Cocoa specs are net short 20,850 contracts at the 1st percentile over 2 years — an extreme short position.
Livestock positioning remains moderate across the complex. Live cattle specs are net long 81,411 contracts at mid-range percentiles. Lean hogs show net long positioning of 75,493 contracts at the 75th percentile over 2 years (91st over 10 years). Feeder cattle positioning is minimal at 8,192 contracts net long.
Cross-Commodity Themes
The March positioning data reveals a clear bifurcation between grain and oilseed complexes versus other agricultural markets. Corn and the entire soybean complex show extreme net long positioning despite comfortable US supply fundamentals — suggesting specs are responding to global supply concerns rather than domestic US conditions.
This contrasts sharply with cotton, wheat, and the softs complex, where positioning generally aligns with fundamental supply conditions. The pattern indicates selective spec buying focused on crops where world supply concerns may override comfortable US balance sheets.
📍 Key Questions for Next Month
- Will corn specs maintain 89th percentile long positioning if the April WASDE shows no further tightening in world S/U conditions?
- Can soybean specs sustain 97th percentile positioning with US S/U remaining 1.5 percentage points above the 5-year average?
- Will wheat HRW positioning at the 99th percentile for longs converge toward the overall wheat short positioning as US supply remains abundant?
