This signal is a deliberately transparent sum of its parts — each component shows its contribution and the reason, so the verdict is never a black box. The cost-build coefficients are public-literature starting defaults pending field calibration; weigh the components, not just the headline.

The gap between a region's realizable price and its cash cost is the producer margin. The EU is a net nitrogen importer, so its producers realize IMPORT PARITY — the landed cost of the marginal import — not the bare FOB benchmark: parity = FOB + $40/t freight. The US is an exporter and realizes ~FOB, so it takes no such adjustment. When parity falls toward the EU cost line, European marginal capacity goes underwater → curtailment → tightening. This margin is stated EX-CARBON: the CBAM charge on imports is real and live since 2026-01, but it cannot be backtested (it is zero across the entire validation period) and its own largest input is a choice, so it is reported separately below rather than folded into a published margin. Cash cost = gas × 33 MMBtu/t NH₃ + opex, then NH₃→urea (coefficients are public-literature defaults, pending calibration).

The European leg is the differentiated read. Europe is a net nitrogen importer, so an EU producer realizes import parity — the landed cost of the marginal import — rather than the bare E. Europe FOB benchmark: $400 FOB + $40 freight = $440/t. Against a TTF cash cost of $428/t that leaves $+12/t (0 months underwater). This is an ex-carbon margin on both sides: it excludes the $43/t CBAM charge on the marginal import and the $2/t the EU producer now pays under the matching free-allowance phase-out. Carbon is live and legally operative, but it is zero across every month we could validate against, so we report it beside the margin rather than inside it. When that margin goes underwater the marginal tonne of world urea capacity is losing money → curtailment → a tightening world balance that transmits to Brazil's import bill.

Total monthly fertilizer imports (all four nutrient groups) against the 2011–2024 by-calendar-month seasonal normal. Arrivals well below normal flag thin near-term availability; well above flag restocking. Source: Comex Stat (SECEX/MDIC).

Concentration is the procurement-risk lens: a nutrient sourced heavily from a small set of at-risk origins is fragile to a single sanctions, export-quota, or logistics shock. The swing column shows where lower-risk backfill would have to come from.

Both ratios are fertilizer $/t over crop $/t (CBOT corn & soybeans). A rising ratio means fertilizer is expensive relative to crop revenue — the 6–9 month leading indicator for application cuts and next-season area/yield risk.

Today's affordability sets next season's application and area decisions, which set crop supply 6–9 months out. Urea:Corn at 2.287 and MOP:Soybean at 0.902 — read rising ratios as application-cut risk building.
The CBOT ratios above are the global/trader lens; this is what a Brazilian grower actually faces at the farmgate. Coffee is graded against fixed Barter Matrix thresholds (<3 highly accessible / 3–4.5 neutral / >4.5 expensive) — an analytical proxy modeled on historical CONAB input-cost datasets and cooperative barter behavior observed during the 2022 supply shock; soybean and corn are graded against their own still-short price history. Lower = fertilizer more accessible relative to the crop. ⚠ marks months thinly reported across states. We publish the ratio and regime band only, never the underlying price series.

(est.) — CONAB had not yet printed coffee farmgate for this month, so it is carried forward from the ICE arabica terminal at the trailing farm-to-terminal discount (0.81, contemporaneous), the stable leg of the basis; the fertilizer side is real CONAB.
