Sugar Prices India: Why Ethanol Diversion Isn’t to Blame

Sugar prices in India have risen sharply just as the country enters the crucial festival season, but the government says the surge cannot simply be blamed on sugarcane being diverted to ethanol.

The more important story is a supply squeeze. Sugar production has fallen well below earlier expectations after weather-related damage in major producing states, while inventories have tightened and buyers have begun building stocks ahead of festivals. The government has also pointed to speculation and hoarding as factors contributing to the price rise.

The distinction matters because ethanol has become a major part of India’s Energy policy. The country has spent years encouraging sugar mills to produce ethanol for blending with petrol, creating a new revenue stream for the Sugar Industry. But current data suggests that the amount of sugar diverted toward ethanol is not large enough, on its own, to explain the latest jump in retail prices.

The immediate problem is that the sugar India expected to have this season simply did not materialise in the quantities initially projected.

How much have sugar prices risen?

The increase has been unusually rapid.

According to the latest government figures, the all-India average retail price rose from Rs 48.18 per kg on July 20 to Rs 55.70 per kg on August 20. The source material also cites an all-India modal retail price of Rs 65 per kg, highlighting the difference that can exist between different measures of retail pricing and market quotations.

Wholesale and ex-mill prices have also climbed significantly. In Maharashtra, Uttar Pradesh and Karnataka, mills were receiving substantially more for sugar in August than they had earlier in the month.

That matters because a sustained increase in ex-mill prices eventually feeds through the supply chain to wholesalers, Food manufacturers, sweet shops and households.

The timing is particularly sensitive. India is heading into a period when demand for sugar typically increases as households purchase sweets and packaged foods and businesses prepare for festivals including Dussehra and Diwali.

The real problem: production fell far below expectations

The most important number in the current sugar story is not the quantity diverted to ethanol. It is the gap between expected and actual sugar production.

Earlier estimates had painted a relatively comfortable picture for the 2025-26 sugar season. ISMA initially expected gross sugar production to be around 34.4 million tonnes, with the industry subsequently revising its expectations as the season progressed. Its third advance estimate in February put gross output at about 32.4 million tonnes and net production, after ethanol diversion, at around 29.3 million tonnes.

More recent government estimates put gross production at roughly 30.6 million tonnes, significantly below the original expectation.

That revision is crucial. Even before considering ethanol, there is a substantial hole between the amount of sugar that was expected to be produced and what mills are ultimately able to make.

When production estimates fall by millions of tonnes, the effect on inventories can be much larger than the quantity diverted to ethanol. The market consequently becomes more sensitive to any additional demand, stockholding or uncertainty about how much sugar mills actually have available for sale.

Weather damage hit key sugar-producing states

The production shortfall has its roots largely in the sugarcane crop.

Maharashtra and Karnataka are among India’s most important sugar-producing states, and their cane crops were affected by adverse weather conditions. The supplied account points specifically to excessive rainfall in September and October, combined with a delayed withdrawal of the southwest monsoon.

Waterlogged fields can create difficult growing conditions for sugarcane. Reduced sunlight and poor aeration can affect plant growth and sucrose accumulation, which matters directly to the quantity of sugar that mills can extract from harvested cane.

The consequences became visible when actual production failed to match earlier expectations.

Earlier projections had placed Maharashtra’s production at around 13 million tonnes and Karnataka’s at more than 6 million tonnes. Actual output subsequently fell well short of those estimates.

Uttar Pradesh faced a different problem. The state’s crop was affected by diseases and pests, including red rot and top shoot borer. The susceptibility of the widely grown Co-0238 variety has also become a concern for yields and sugar recovery.

The result was a nationwide production picture that was considerably weaker than the optimistic forecasts made at the beginning of the season.

Why lower production matters more than ethanol diversion

At first glance, around 3 million tonnes of sugar diverted for ethanol production may look large. It is certainly a meaningful quantity in a market where inventories are tightening.

But there is a crucial distinction between gross production and net sugar production.

Gross production measures the sugar produced before accounting for sugarcane juice, syrup or molasses diverted toward ethanol. Net production is what remains available as sugar after that diversion.

If gross production had matched earlier expectations, the ethanol allocation would have been easier for the market to absorb. Instead, the production base itself shrank sharply.

That means the ethanol diversion became more visible because it occurred against a much smaller-than-expected supply pool.

In other words, the argument is not that ethanol has no effect on sugar availability. It does. The more precise point is that the current price spike cannot be explained primarily by ethanol diversion when the larger shock has come from lower overall sugar production.

Government data challenges the ethanol explanation

The Union government has explicitly rejected the claim that ethanol diversion is responsible for the recent sugar-price surge.

The Ministry of Consumer Affairs, Food and Public Distribution said the share of sugar diverted for ethanol declined from around 12% in 2022-23 to about 9% in 2025-26. The ministry also said nearly three-fourths of ethanol production now comes from grain-based feedstocks, particularly maize and rice.

That is an important change in the structure of India’s ethanol programme.

Ethanol can be produced from several feedstocks. In the sugar industry, the relevant inputs include sugarcane juice, syrup and different grades of molasses. But ethanol production is no longer dependent on sugarcane-derived feedstock to the same extent because grain-based production has expanded.

For the current ethanol supply period, the source data indicates that only about one-third of ethanol supplied to oil marketing companies came from sugarcane-based feedstocks, while the majority came from grains.

That weakens the argument that the entire increase in sugar prices can be attributed to the government’s ethanol-blending programme.

Then why did the market turn suddenly bullish?

Production explains the fundamental shortage, but it does not completely explain why prices accelerated so rapidly from July.

Market behaviour appears to have amplified the underlying supply problem.

Some mills were reportedly under financial pressure and had sold sugar beyond their regular monthly release quotas. That may have left certain mills with less physical inventory than their reported stock figures suggested.

At the same time, traders and bulk consumers began anticipating tighter supplies. Larger merchants, stockists and industrial buyers reportedly started taking positions before the major festival demand arrived.

Once buyers begin accumulating stocks because they expect prices to rise, the market can tighten further in the short term.

Mills may also become reluctant to sell aggressively if they believe the price will be higher later. This creates a feedback loop: expectations of scarcity encourage stock accumulation, reduced immediate availability pushes prices higher, and higher prices strengthen the incentive to hold stocks.

The next sugar crop is also causing concern

The problem is not limited to the sugar already produced.

Market participants are also looking ahead to the 2026-27 season, which is due to begin as mills prepare for the next cane-crushing cycle.

Rainfall patterns in June raised concerns in important sugar-producing regions, particularly Maharashtra and Karnataka. If weather conditions reduce cane yields again, the market could face another year in which production fails to meet expectations.

This explains why traders have been willing to pay more for available sugar even before the new crushing season begins.

The market is effectively pricing not just today’s shortage but also uncertainty about tomorrow’s supply.

Why festival demand is making the problem worse

India’s festival calendar is especially important for the sugar market.

Demand from households, sweet manufacturers, restaurants, bakeries and packaged-food companies tends to rise around major festivals. Dussehra and Diwali are particularly important periods for the traditional sweets market.

When supply is already tight, even a normal seasonal increase in demand can produce a disproportionately large price response.

This is why the timing of the current price surge is significant. The market is entering a period of stronger consumption while inventories are already under pressure.

For consumers, the impact extends beyond a bag of household sugar. Sugar is a basic ingredient in confectionery, beverages, bakery products and traditional sweets. Higher raw-material costs can therefore spread through several parts of the food economy.

What the government has done to control prices

The government has responded with several measures aimed at increasing domestic availability and preventing excessive stock accumulation.

First, India banned sugar exports until September 30, 2026. The objective was to retain domestic supplies rather than allow additional sugar to leave the country while local prices were rising.

The government has also imposed stockholding restrictions on sugar dealers. The order that took effect on August 1 is intended to discourage hoarding and speculative accumulation and ensure that sugar continues moving through the domestic supply chain.

In addition, the government has recently permitted 1 million tonnes of raw sugar to be imported at zero duty until October 31. India normally applies a much higher import duty on sugar, so the temporary exemption is designed to make overseas supplies more competitive and improve availability before the peak festival period.

Reuters reported that the move is expected to allow port-based refineries to process imported raw sugar for the domestic market, potentially adding supply before the next crushing season begins. :contentReference[oaicite:0]{index=0}

Why duty-free imports could matter

Imports cannot solve a structural production problem overnight, but they can help bridge a temporary supply gap.

The timing is important because India’s next sugarcane crushing season is expected to begin from late October into November. Imported raw sugar can potentially be processed before domestic mills have fully restarted operations.

That creates a bridge between the depleted end-of-season inventory and the arrival of fresh domestic production.

The effectiveness of the measure will depend on how quickly imports arrive, how much refined sugar enters the domestic market and whether traders and bulk consumers continue accumulating stocks.

Stock limits are another attempt to cool the market

The government has also targeted the possibility that expectations of higher prices could encourage excessive inventory accumulation.

In July, it imposed stockholding limits on sugar dealers, with the restrictions running through November. The government said the move was intended to curb hoarding and speculative trading and maintain orderly domestic supplies. :contentReference[oaicite:1]{index=1}

That policy addresses a different part of the problem from imports. Imports increase the physical supply of sugar, while stock limits attempt to ensure that existing supplies do not become unnecessarily concentrated in warehouses.

Both measures therefore target the same objective from different directions: keeping sugar moving into the market during a period of tight availability.

Could the government restrict sugar-to-ethanol diversion next season?

This is where the ethanol debate could become more important.

The government is reportedly considering ways to prioritise sugar availability in the coming season, including potentially restricting some sugarcane-derived feedstocks for ethanol.

Such a move would not necessarily mean abandoning India’s ethanol-blending programme. Instead, policymakers could seek to adjust the mix of feedstocks used for ethanol when sugar supplies are unusually tight.

One possible approach would be to rely more heavily on grain-based ethanol while preserving more sugarcane-derived material for sugar production.

Reuters reported earlier this month that the government was considering limiting the use of sugarcane for ethanol in the next season, with the possibility of shifting more ethanol production toward maize and rice. :contentReference[oaicite:2]{index=2}

That would allow policymakers to pursue two objectives at once: protect domestic sugar availability while maintaining progress toward Ethanol Blending.

The bigger policy dilemma: sugar versus ethanol

The current episode exposes a genuine policy trade-off even if ethanol diversion is not the main cause of today’s price spike.

India wants higher ethanol blending because domestically produced ethanol can reduce dependence on imported petrol components and provide another market for agricultural commodities and sugar-industry by-products.

For sugar mills, ethanol also provides an alternative revenue stream and can improve the industry’s ability to pay cane farmers.

But when sugar supplies become tight, diverting sugar-producing feedstock toward ethanol can attract criticism because every tonne of potential sugar matters more to the domestic market.

The challenge for policymakers is therefore not simply choosing between sugar and ethanol. It is deciding how the available feedstock should be allocated when weather, production and inventories change dramatically from one season to another.

What the current numbers really tell us

The simplest explanation for the sugar-price surge is also the most important: India produced less sugar than expected, inventories became tighter, and buyers entered the market ahead of the festival season.

Ethanol diversion is part of the supply equation, but it is not the entire equation.

The government’s latest position is supported by the changing composition of ethanol production. With most ethanol now coming from grain-based feedstocks and the sugar share of ethanol feedstock having declined, blaming the entire sugar-price rally on ethanol oversimplifies what has happened.

The production shortfall is much harder to dismiss. Earlier forecasts anticipated substantially more sugar than mills ultimately produced, particularly after adverse weather affected major cane-producing states.

What could happen to sugar prices next?

The immediate outlook depends on three factors: how much sugar remains physically available, how quickly imports arrive and how mills and traders behave ahead of the festival season.

If duty-free imports successfully add supply and stockholding restrictions discourage excessive accumulation, the current price pressure could ease.

If imported sugar arrives slowly while festival demand remains strong, prices could stay elevated until domestic mills begin crushing the next cane crop.

The next sugarcane harvest will ultimately be the more important factor for the medium-term outlook. If weather conditions support a better crop, production could recover and ease the supply squeeze. If major producing states face another difficult season, the market could remain vulnerable.

The bottom line on ethanol and sugar prices

It is tempting to point to India’s ethanol programme whenever sugar prices rise because sugarcane is an important feedstock for ethanol. But the current price shock has a more complicated explanation.

Production fell far below early expectations after weather damage and crop problems affected major producing states. Stocks tightened, traders and bulk consumers increased purchases, and festival demand is approaching. Speculation and stockholding behaviour may have amplified the squeeze.

Ethanol diversion did reduce the quantity of sugar available compared with gross production, but the latest government data shows that its share has declined and that most ethanol is now produced from grains.

The immediate policy response therefore makes sense as a supply-management exercise: keep exports restricted, bring in temporary imports, limit excessive stockholding and ensure mills and traders release sugar into the domestic market.

The more difficult question comes next season. If sugar supplies remain vulnerable, policymakers may have to fine-tune the balance between food availability and ethanol production. That debate is likely to continue, but it should not obscure the central fact behind the current price surge: India’s sugar shortage began with a production problem, and ethanol is only one part of the supply equation.
