Indian Sugar Stocks Surge 20% on Ethanol Policy Reversal: A Game-Changer for the Sugar Industry

On September 2, 2025, Indian sugar stocks skyrocketed by up to 20 percent following the government’s decision to lift restrictions on ethanol production from sugarcane juice, sugar syrup, and molasses for the 2025-26 Ethanol Supply Year (ESY), starting November 1. This policy reversal, announced by the Ministry of Consumer Affairs, Food & Public Distribution, removes quantitative caps imposed in the 2024-25 ESY due to low sugarcane yields, enabling sugar mills to maximize ethanol output. Bolstered by robust monsoon rains and a Supreme Court ruling dismissing challenges to the 20 percent Ethanol Blended Petrol (EBP-20) rollout, the decision has ignited investor enthusiasm, with companies like Rajshree Sugars, Shree Renuka Sugars, and Dhampur Sugar Mills leading the rally. This article explores the drivers behind this surge, the historical context of India’s ethanol policy, future growth prospects, and the broad impacts on the sugar and energy sectors, highlighting Tamil Nadu’s role as a key player in this transformation.

Why This Policy Reversal Matters

The removal of ethanol production limits is a pivotal shift, allowing sugar mills to diversify revenue streams beyond volatile sugar prices, which have risen due to a 16.13 percent drop in sugar production to 23.71 million tonnes in the 2024-25 season. With ethanol fetching higher margins and India aiming for 20 percent petrol blending by 2025-26—and potentially 30 percent by 2030—this policy strengthens energy security, supports sugarcane farmers, and aligns with environmental goals. For investors, the surge signals renewed confidence in sugar companies, particularly those in Tamil Nadu, a major sugarcane hub, as they capitalize on biofuel demand.

Latest Economic Events Driving the Surge

The policy shift was announced on September 1, 2025, following improved sugarcane production forecasts due to two consecutive years of strong monsoon rains, increasing sugarcane acreage to 5.77 million hectares from 5.7 million. The Department of Food and Public Distribution (DFPD) stated that sugar mills can now produce ethanol from cane juice, syrup, B-heavy molasses, and C-heavy molasses without restrictions, with periodic reviews to ensure domestic sugar supply stability. This decision reverses a 2023-24 ban prompted by a 33.7 million-tonne sugar output, down from 37.3 million tonnes, which had prioritized food security over biofuel production.

Key Market Developments

• Stock Market Rally: On September 2, Rajshree Sugars & Chemicals surged 20 percent to Rs 45.36, hitting its upper circuit on the BSE. Shree Renuka Sugars climbed 14 percent to Rs 32.80, Dhampur Sugar Mills rose 12.78 percent to Rs 141.79, and Balrampur Chini Mills gained 7 percent to Rs 580. Other gainers included Uttam Sugar Mills (12 percent), Magadh Sugar & Energy (10 percent), and Triveni Engineering (4.5 percent).
• Supreme Court Backing: On September 1, the Supreme Court dismissed a plea challenging EBP-20, filed by advocate Akshay Malhotra, who argued that vehicles made before April 2023, including BS-VI models, were incompatible with 20 percent ethanol blends. Attorney General R Venkataramani defended the policy, citing benefits to farmers and foreign exchange savings.
• Ethanol Blending Progress: As of July 31, 2025, India’s ethanol blending rate reached 19.05 percent, nearing the 20 percent target set for 2025-26, advanced from 2030 under the National Policy on Biofuels (2018, amended 2022).

Tamil Nadu’s Role

Tamil Nadu, a leading sugarcane-producing state, stands to benefit significantly. With mills like Rajshree Sugars and EID Parry based in the state, the policy is expected to boost local ethanol production, creating jobs and supporting farmers. The state’s robust agricultural infrastructure and proximity to ports facilitate ethanol supply chains, enhancing its role in India’s biofuel ambitions.

Historical Context of India’s Ethanol Policy

India’s ethanol journey began in the 1970s with sugarcane-based production for industrial use, evolving into a strategic biofuel program in the 2000s. The Ethanol Blended Petrol (EBP) program, launched in 2003, aimed to reduce fossil fuel imports and emissions, with key milestones shaping its trajectory.

Key Milestones in Ethanol Policy

• 2003-2007: EBP mandated 5 percent blending, with initial adoption slowed by inconsistent ethanol supplies and state tax complexities.
• 2018: The National Policy on Biofuels set a 20 percent blending target by 2030, later advanced to 2025-26, encouraging use of sugarcane derivatives and grains.
• 2021-2022: India surpassed 10 percent blending by June 2022, ahead of schedule, with ethanol production reaching 500 crore liters by 2022-23, up from 173 crore liters in 2019-20.
• 2023-2024: A ban on sugarcane juice and B-heavy molasses for ethanol was imposed due to a 37.3 to 33.7 million-tonne sugar production drop, prioritizing domestic sugar supply.
• 2025: The policy reversal, supported by an expected 34.9 million-tonne sugar output in 2025-26, lifts caps, boosting ethanol production to meet EBP-20 and future 30 percent targets.

This history reflects India’s balancing act between food security and energy goals, with Tamil Nadu’s sugar mills playing a pivotal role in scaling ethanol output.

Future Scopes and Projections

The policy reversal is projected to increase ethanol production to 600 crore liters by 2026, supporting 5 million tonnes of sugar diversion for ethanol. Analysts forecast a 15-25 percent earnings CAGR for sugar companies over the next three years, driven by ethanol margins and stable sugar prices. Tamil Nadu’s mills, with capacities like Shree Renuka’s 1,250 KLPD and EID Parry’s 920 KLPD, are set to expand to meet demand.

Long-Term Strategic Outlook

By 2030, India aims to achieve 30 percent ethanol blending, potentially reducing crude oil imports by $2 billion annually and cutting carbon emissions by 10 million tonnes. Tamil Nadu could emerge as a biofuel hub, leveraging its sugarcane belt and port infrastructure. Innovations in grain-based ethanol and sustainable farming practices may further diversify feedstocks, mitigating weather-related risks.

Potential Challenges

• Supply Risks: Sugarcane yields remain vulnerable to droughts or floods, with a 16 percent production drop in 2024-25 highlighting volatility.
• Pricing Pressures: Stagnant ethanol prices versus rising sugarcane costs could squeeze margins, as seen in 2024-25 when sugar sales became more profitable.
• Regulatory Uncertainty: Potential US tariffs on Indian ethanol exports, as flagged by ISMA, could hinder trade, while domestic policy shifts may create volatility.
• EV Competition: Rising electric vehicle adoption could temper long-term ethanol demand, though petrol vehicles remain dominant in India.

Impacts on the Indian Economy and Stakeholders

The policy reversal is a lifeline for sugar mills, enhancing profitability, stabilizing farmer incomes, and advancing India’s green energy goals. Tamil Nadu’s economy, with its strong sugar industry, will see significant benefits, including job creation and export potential.

Sector-Wise Impacts

Sugar and Ethanol Industry

• Impact: The policy allows mills to maximize ethanol output, boosting revenues by 20-30 percent due to higher margins (ethanol at Rs 59.13/liter versus sugar’s volatile Rs 38/kg). Companies like Shree Renuka and Balrampur Chini will expand distillery capacities, with Tamil Nadu mills like EID Parry targeting 1,400 KLPD by 2026.
• Economic Contribution: The sector could add Rs 10,000 crore to GDP by 2027, with Tamil Nadu contributing 15 percent due to its milling infrastructure.
• Business Opportunities: Distillery equipment suppliers and biofuel tech firms will see demand, while SMEs in Tamil Nadu’s sugarcane belt benefit from supply chain contracts.
