Research & Analysis

The July WASDE's split verdict collapsed into a unanimous grain rally: managed money bought the entire complex into a rising tape — corn added the most on the board for a third straight week, the soybean long we'd called stalled broke out +52,212, soybean meal piled on 27,300, and both wheats ripped 7–10%. Soy oil, soybeans, and gold now hold the board's three biggest longs. In the pens the two extremes mean-reverted: the record cattle long liquidated to a median 51st percentile, and the record hog short covered on a 6.7% pop — the squeeze we called a week early. Copper broke to the top of its range, and crude rallied 7% without the specs. Opens with a scorecard that owns the week's miss — and a board-crush chart showing the tell we read backwards.

A week after the July WASDE split the verdict, funds acted on the grade. They pressed the confirmed longs — corn added the most of any market on the board even as its price slipped, buying the stocks cut rather than chasing the tape — while the crowded, unconfirmed soybean long stalled and the money rotated into soybean oil at the 97th percentile. Live cattle's record long shed 16,997 contracts in the biggest one-week liquidation on the board; the lean-hog squeeze we flagged fizzled as the record short got paid; and natural-gas specs doubled down to a −105,501 short. Opens with a scorecard grading last week's five calls — three hits, one partial, one miss.

We read the entire Fundação Procafé archive — 529 monthly plant-health bulletins from 2010 to 2026 — and turned it into a coffee leaf-rust time series no one else has. June 2026 rust was genuinely low for June (rank 3 of 17), not just moderate; our ERA5 temperature matches Procafé's own field gauge to r=0.98 over 196 months (rainfall is noisier, and blind to dew); warmer regions carry more rust on average but the year-to-year ranking reshuffles; and leaf retention — how much canopy a tree keeps after a rust year — is a leading indicator of the 2027 crop that balance sheets can't see. Here's what it changed in our signal.

Every Thursday the USDA export-sales number moves the ag desks — and it's the most misread report on the screen. Commitments front-load (half to 85% of the soybean year is booked by early December), overshoot the final total, then wash back out on cancellations. Across soybeans, corn and cotton, you can't extrapolate that pace to beat WASDE — it misleads exactly when it looks most exciting. Here's what the weekly report is actually good for.

A living, cited digest of what the USDA's own reports — WASDE-cycle circulars and FAS attaché posts — say about China's grain demand, kept separate from our own read. China's corn import book has collapsed to 5–6 MMT with zero U.S. corn on the books; its soybean book is huge and growing (~115 MMT, ~61% of world trade) but the tonnage routes to Brazil and Argentina. Attaché figures are flagged as staff research, not official; every claim carries its source; refreshed each WASDE cycle.

Funds chased the weather rally straight into the July WASDE — corn flipped from a 46k net short to net long in the single biggest swing on the board, soybeans piled in on a record open-interest build, HRW wheat extended its long. Then the report split the verdict: it cut corn and wheat ending stocks, validating those longs, but held soybean stocks flat and raised cotton's, leaving those two riding on weather alone. Cattle's record long bled a second week as futures broke 7.7%, hogs' record short began to squeeze, and sugar booked a second straight giant short-cover.

The July WASDE cut new-crop corn ending stocks 170 million bushels — not on a smaller crop, but on demand running hot into a stack of burning northern-hemisphere fields, with France's corn crop the smallest since 1990/91. Meanwhile China's return to U.S. grain, promised in headlines for months, still refuses to appear in the ledger: corn imports pinned at a multi-year-low 5–6 MMT and zero U.S. corn under outstanding sales, while the one place Chinese demand is growing — soybeans — ships its cargo to Brazil. The promise moves prices; the proof moves through someone else's port.

Most sugar commentary starts with a weather map. But the single most price-relevant lever in the world sugar balance is a fortnightly decision inside Brazilian mills: make sugar, or make ethanol. This is how that decision is priced — sugar-ethanol parity, the CONAB Center-South mill-mix, and the 70% pump rule — and why it belongs on a softs trader's screen next to the No.11 net position.

The June 30 Acreage and Grain Stocks reports landed in this holiday-delayed COT — and funds trimmed grain shorts into flat prices, pre-report de-risking rather than a chase, while the July contract roll flatters the post-report rally. The real surprises sat where positioning wasn't: winter-wheat acres cut hard onto the worst-conditioned HRW crop in years, soybean acres lifted to the largest in years. The protein split resolved toward price as live cattle broke 7% still record long, and sugar booked the board's biggest short-cover.

A third of Brazil's grain no longer sails from São Paulo — it rides barges down the Amazon and its tributaries, the Arco Norte. Whether those rivers are deep enough to float a loaded barge in October is set, months earlier, by how warm a patch of the tropical North Atlantic was back in April. The geography of that teleconnection, the two-leg truck-and-barge chain that carries the crop, Brazil's thin logistics backbone, and how we turned it into a validated, months-ahead navigability forecast.

Once a month, one USDA report resets the terms of debate in every grain, oilseed and cotton market at once. Its job is to take everything known about how much of a crop exists and how much will be used, and reconcile it into a single balance sheet — so you don't have to assemble trade, crush, feed and stocks yourself. What the WASDE is, how the balance sheet works, why traders read it, and how ending stocks becomes the stocks-to-use ratio the market actually trades.

Fertilizer is the quiet hinge between the energy market and the food market — the nitrogen in a bag of urea was, months earlier, natural gas. A guide to our four Fertilizer Supply-Risk reports — Brazil, India, the US and the global producers — what each tracks, why each region sits on the chain differently, and how to read the Tightening / Neutral / Easing signal at the top of every one.

HRW wheat gave back its entire drought-cover bounce and flipped net short again — into a Kansas crop still 23% in severe drought, heading into harvest. Inside the soy complex the holdout finally cracked at the edges as oil began to erode while meal went flat. Live cattle pushed to a fresh extreme long against near-record commercial shorts, lean hogs sank deeper into the board's most bearish stance, and crude buckled to the bottom of its range.

They sit side by side on the board and both say "cattle," but they are not two prices for one thing — they are the same animal at two stages of its life, joined by corn and time. How the cattle crush works, why feeder cattle behaves as a leveraged bet on live cattle minus corn, and why the spread between them sits near the widest on record — with the herd-rebuild twist that keeps feeders tight precisely when you'd expect relief.

A holiday-delayed COT caught the grain board mid-liquidation, but with a clear new tell: HRW wheat snapped back to net long as funds covered into a Kansas crop now 24% in severe drought. Corn and soybeans kept bleeding while the soy complex divergence widened — meal collapsed toward flat as oil held. Beyond grains, live cattle re-loaded an extreme long, nat-gas bears took their biggest cover of the cycle, and sugar pressed to a fresh multi-year-low short.

Most people watch El Niño and assume that is the ocean-climate story. The Indian Ocean Dipole is a separate driver that frequently runs alongside ENSO, sometimes runs entirely without it (2019), and peaks two months earlier — which is why we publish two ocean indices rather than one. Forty-four years of data on why one index cannot stand in for the other.

When ENSO and the Indian Ocean Dipole line up, their rainfall effects can reinforce into floods or drought over East African coffee — or, for the Indian monsoon, quietly cancel. The phase-combination matrix, how rare a true alignment actually is, and an honest account of where the record goes silent.

Frost is the most violent weather risk in coffee, and the nights that do the damage are calm, clear and dry — the exact inverse of the wet nights that wake leaf rust. The physics of a killing frost in Brazil's arabica belt, why we model an estimated leaf temperature rather than the thermometer reading, and where the signal falls short.

Why we monitor environmental conditions for coffee leaf rust (Hemileia vastatrix) across seven origins — the two-stage thermal biology behind the signal, why we also track input-affordability, the model's known limitations, and a defense of its value as a leading, transparent indicator.

The grain board broke. Corn managed money crossed into net short on a 120,000-contract liquidation week — the largest of 2026 — and both winter wheats followed it under zero. The soy complex was gutted, meal longs halved, yet soybean oil held its crowded long. Two days later, the June WASDE and Brazil's CONAB survey confirmed the ample-supply read the specs had already traded.

In the week the grain board flipped net short, one long refused to move. Soybean oil held a 99th-percentile position while corn round-tripped to net short and meal — crushed from the same bean — was halved. The June WASDE soybean sheet carries two numbers that disagree: a 90th-percentile-ample world stocks-to-use and a 20th-percentile-tight ex-China figure. A look at which one the long might be reading — and the open questions we're leaving open.

Last week's three open questions got answered. Corn logged a second straight ~90k liquidation week after a healthy first condition print — the spec long is now two-thirds off its peak. Lean hog longs flipped net short, completing a round trip from the February high. Natural gas bears took their first covering, and Chicago wheat shorts tripled down ahead of the June WASDE.

El Niño onset is now forecast at 96–98% probability by July. The arabica flowering window opens in October. The USDA flags the developing event as the primary downside risk to its record 2026/27 Brazil forecast. A crop-timing analysis: the SACZ mechanism, the phenological calendar, and the impact from onset through recovery.

Managed money trimmed across the board. Corn saw the largest single-week spec reduction of 2026. Lean hog longs are nearly fully unwound after five months. Natural gas bears pushed to −134k contracts at $3.10 Henry Hub. Winter wheat conditions matched 2023 spring lows.

US winter wheat G/E ratings are back at 2023 spring lows — the last year of significant HRW abandonment. A look at what the data showed during that cycle, how the 2026 state-by-state setup compares, and the signal calendar to watch from now through the July WASDE.

The Southern Plains drought fingerprint from this year's La Niña reads differently in HRW wheat, cattle, and soybeans. A breakdown of what the Drought Monitor, USDA condition data, and CFTC positioning are showing — and where the stories diverge.

El Niño and La Niña are the most powerful systematic supply risk factors in commodity markets — and the most underused. A practical guide to reading ENSO signals across coffee, grains, softs, and energy.

NOAA has officially transitioned from ONI to RONI — the Relative Oceanic Niño Index. For commodity traders, this is not a technical footnote. It changes how you read ENSO signals, validate historical analogs, and manage supply risk.
