Every sugarcane crisis comes with a morality play: angry farmers, stressed mills, a politician caught in the middle. The spreadsheet version is less theatrical and more useful. It asks one question: who controls each number between the field and the bank account?

In Karnataka, Chief Minister D.K. Shivakumar has answered it himself, in a letter to Prime Minister Narendra Modi. The state will do what it can, he wrote, but "the farmers' primary demands can only be met by the Government of India."

The chain, link by link

Cane economics is a sandwich. One slice is what mills must pay for cane. The other is what mills can earn from sugar and ethanol. Delhi bakes both slices.

The input price. The Fair and Remunerative Price (FRP) is the benchmark for cane. According to the letter, it has risen from ₹2,750 to ₹3,650 per tonne. It is tied to a base recovery rate, the share of sugar extracted from cane, which was raised in stages from 9.5% to 10.25%. When a region's recovery falls below the base, the FRP is cut.

The output price. The Minimum Selling Price (MSP) of sugar, the floor under mill revenue, has sat at ₹31 per kg since February 14, 2019, the letter says. The main input has climbed. The floor on the main product has not budged.

The second revenue stream. Ethanol is the mills' other product. Shivakumar says prices for ethanol from cane juice and B-heavy molasses have been flat since 2022-23, while grain-based ethanol prices have risen.

That is a squeeze by construction. Index one side of a margin upward, freeze the other, and something gives. Mills argue, and the chief minister's letter echoes, that at 2019 sugar prices they cannot pay the fair price.

Where the state's power ends

The state has real tools, but they sit at the edges. The letter lists them: digital load cells to stop weighing irregularities at factories, monthly inspections by district-level teams, and a directive that laboratories obtain NABL accreditation. The state also promised to monitor sugar factories and to cooperate fully with the committee headed by farm scientist Ramesh Chand, including sharing data.

Don't dismiss these. Weighing and testing disputes are a classic way farmers lose money without any price changing on paper. An understated cane weight or recovery reading is a hidden price cut. Better scales and accredited labs pull the realised price closer to the stated one.

Now notice what they leave alone: the sugar floor, the FRP recovery formula, the ethanol procurement terms. Those belong to the Centre. The state can police the arithmetic. It cannot rewrite the formula.

The ethanol twist

Timing made it worse. On the day the Centre announced it was excluding sugarcane-based ethanol from oil company tenders, the chief minister asked it to reconsider. As the letter describes it, the Oil Marketing Companies' tender of October 16, 2026, covering November 2026 to October 2027, excludes ethanol from cane juice, sugar syrup and B-heavy molasses. Ethanol from C-heavy molasses stays eligible.

The letter puts Karnataka's annual capacity for sugarcane-based ethanol at 225 crore litres. The mechanism is simple: less ethanol offtake, less mill revenue, slower payments to growers. Ethanol was meant to cushion mills against sugar's price cycle. Narrow the eligible feedstocks and the cushion thins precisely where cane-heavy producers need it.

Two proposals worth reading closely

The letter forwards a farmers' association request for separate MSPs for domestic and commercial sugar. The logic: shield household consumers, let bulk commercial buyers pay more, lift mill margins so mills can pay growers more. It moves the burden of a higher floor away from kitchens. Whether such a split is workable, the letter does not say, and neither will I.

The recovery-rate demand is subtler. Shivakumar argues recovery depends on soil, climate and crushing timing, none of which farmers control, so lower-recovery regions never receive the base FRP. Resetting the base to 9.5% would shift some of that risk from growers to mills. That is a distributional choice dressed as a technical one.

The cost of waiting

The clock is not neutral. Crushing has not begun in North Karnataka because of the protests in Belagavi. Ready cane stands in the fields, losing weight and sugar content every day. Delay shrinks the very pie being fought over: farmers have less cane to sell, mills less sugar to recover.

The farmers say they will not end the agitation without an assurance from the Centre. The chief minister says he visited them in Kittur and met Union Food Minister Pralhad Joshi. He argued that some decisions can be taken immediately while the Chand committee works, and flagged the public inconvenience from road blocks.

What the split means

For growers, the practical reading is that state action can plug leaks but cannot lift the headline price. For mills, the squeeze is policy-made, and so is any relief. For the state, the position is awkward: the protests block its roads, but it holds few of the levers.

When prices are set centrally and enforcement is local, accountability blurs.

Farmers blame the mill, the mill blames the floor price, the state blames Delhi. Each is partly right, which is why the dispute drags on.

I won't guess how the Centre responds. The sources don't say, and forecasts are cheap. What the numbers do say is that a 2019 floor, a rising FRP and frozen ethanol prices cannot coexist for long. Someone absorbs the gap. The only open question is who.
