Shares of India’s leading automakers jumped sharply on August 18, after reports indicated that the government is weighing a possible GST cut on entry-level two-wheelers, compact cars, and hybrids. The speculation lifted the Nifty Auto index, with Hero MotoCorp gaining more than 8% to become the day’s top performer.
The Indian automobile sector, a cornerstone of the country’s manufacturing and mobility ecosystem, witnessed a sharp upswing in investor sentiment on Monday, August 18, 2025. Major listed players including Hero MotoCorp Ltd., Maruti Suzuki India Ltd., Bajaj Auto Ltd., Mahindra & Mahindra Ltd., and Tata Motors Ltd. saw their shares rally between 3% and 8% amid reports that the government may soon announce a uniform Goods and Services Tax (GST) rate for mass-market vehicles.
Currently, vehicles in India are taxed under multiple GST slabs depending on engine size, vehicle length, and ground clearance. This system places mass-market two-wheelers and small cars in the 28–31% tax bracket, while luxury cars and SUVs attract up to 40% including cess. According to reports, policymakers are now evaluating a simplified framework with a flat 18% GST rate for mass-market segments.
The reform, which aligns with Prime Minister Narendra Modi’s recent Independence Day announcement of moving towards a two-tier GST structure, could be implemented as early as the festive season around Diwali. If approved, this would lower the cost of two-wheelers under 350cc, compact cars up to 1,200cc engine capacity, and select hybrid vehicles, thereby boosting affordability for middle-income households.

Hero MotoCorp Ltd., headquartered in New Delhi, emerged as the biggest gainer with its stock climbing over 8%. As the world’s largest two-wheeler manufacturer and a market leader in the entry-level motorcycle segment, Hero MotoCorp stands to benefit significantly from lower taxation on budget-friendly motorcycles.
Maruti Suzuki India Ltd., based in Gurugram, Haryana, also saw strong buying interest. As the country’s largest carmaker, Maruti Suzuki has a vast presence in the small car category, which could see a major boost in demand if prices decline due to a tax cut.
Bajaj Auto Ltd., headquartered in Pune and known for its motorcycles and three-wheelers, rose steadily on expectations that an 18% GST slab would support sales momentum in commuter motorcycles.
Mahindra & Mahindra Ltd. (M&M), based in Mumbai, gained on prospects that its compact SUVs and passenger vehicles may become more affordable under the revised structure.

Tata Motors Ltd., another Mumbai-headquartered automobile giant with a wide portfolio spanning passenger vehicles and electric cars, also benefited from investor optimism.
The rally reflected across the broader market as the Nifty Auto index surged 3.5% to 24,958 points in early trade, with all major automakers trading in positive territory. Analysts believe that the move could invigorate rural and urban demand, while also providing momentum to auto ancillaries, suppliers, and the broader automobile value chain.
With the festive season ahead, expectations of a GST cut have injected renewed confidence into the stock market, signaling possible relief for consumers and growth opportunities for India’s automotive industry.
