Sugar–Ethanol Parity & Mill-Mix — Tightening, July 2026

Sugar–Ethanol Parity & Mill-Mix — 2026-07
Parity tilt signal	Tightening (tilt +0.52) — ethanol-favored — less sugar made (bullish NY11)
Component roll-up	Parity (leading) +0.34; Mill-mix (realized) -0.22; Demand (tension) +0.40
Sugar netback	R$1.54/kg ATR (NY11 14.80¢, BRL 5.11)
Ethanol netback	R$1.74/kg ATR (ANP hydrous pump R$3.78/L)
Parity (SEP)	0.887 (seasonal-z -0.69)
Realized CS sugar-mix	48.6% (safra 2026/27, band median 45.92%, z 0.73)
Pump parity (E/G)	0.5869 vs 0.70 breakeven (demand-z +1.98)

Sugar-Supply Tilt

Tightening

Net tilt +0.52 · ≥ +0.5 tightening (bullish) / ≤ −0.5 easing (bearish)

+0.34

Parity (leading) z -0.69 · near-normal

Sugar-vs-ethanol netback parity (SEP), seasonally z-scored. Above band = sugar-favored → more sugar → bearish.

-0.22

Mill-mix (realized) z +0.73 · near-normal

Realized CS sugar-mix % vs its multi-year band (CONAB). Above band = mills already maxing sugar → bearish.

+0.40

Demand (tension) z +1.98 · high

Hydrous pump parity vs the 70% breakeven (ANP). Ethanol competitive → cane pulled to fuel → bullish.

Read positive as sugar-supportive: cane pulled toward ethanol, so less sugar is made — bullish NY11. Negative is sugar-favored: mills max the sugar mix — bearish. This is a deliberately transparent sum — parity leads, the CONAB mill-mix confirms, ANP demand is the tension underneath. The netback basis, ex-mill wedge and blend weights are documented starting constants pending calibration; weigh the components, not just the headline.

safra 2026/27

Each route valued as R$ per kg of recoverable sugar (ATR): the sugar leg is NY11 × BRL/USD × mill-realization basis; the ethanol leg is the ANP hydrous pump price bridged to an ex-mill netback. When the sugar line pulls above ethanol (SEP > 1) mills make sugar; when ethanol leads (SEP < 1) cane is diverted to fuel — the price-relevant supply lever.

This is the second energy→ag hinge, the sibling of gas→urea: when crude and gasoline fall, ethanol weakens and mills pivot to sugar — an energy shock landing on the sugar balance sheet. Current parity SEP 0.89 (ethanol-favored), seasonally below its July 2026 norm.

What the mills actually did, from CONAB's per-safra cane survey: the share of recoverable sugar (ATR) turned into sugar rather than ethanol, reconstructed on an ATR basis. The current safra is highlighted. 2018/19–2019/20 near 35% (ethanol-favored) and 2023/24+ near 49–51% (max-sugar) are the realized regimes the parity is meant to lead. Source: CONAB.

Parity sets the incentive; the mill-mix is the realized allocation. When the two disagree — parity says ethanol but the mix keeps climbing to sugar, or vice versa — that divergence is the interesting signal. Current safra 2026/27 at 48.6% vs a 45.92% multi-year median.

At an energy-equivalence near 70%, flex-fuel drivers switch to hydrous ethanol below the line and to gasoline above it. Sustained sub-0.70 keeps domestic ethanol demand — and mill ethanol netbacks — firm, pulling cane away from sugar. SP pump prices, ANP. (Sales-volume demand leg is a planned enrichment; v1 uses the pump parity.)

A signal is only worth reading if it fired correctly when the answer is already known. Across the crude-collapse sugar pivot (2020), the low-sugar ethanol stretch (2019) and the high-price max-sugar run (2023), the tilt lands on the right side each time — validation of direction, not a promise of magnitude.
