On October 7, 2026, the Reserve Bank of India raised the repo rate by 25 basis points to 5.5%, the first hike since February 2023. The move shifted the policy stance from neutral to calibrated tightening and removed rate cuts from the table. Auto stocks reacted immediately, with the Nifty Auto index falling 1.6% that day and almost all of its 15 constituent stocks closing in the red. The RBI’s action marked the first interest‑rate increase in more than three years for the country’s monetary policy.

Despite the headline impact on auto shares, nine years of sales data reveal that vehicle demand remains largely insensitive to rate changes. Analysts matched each fiscal year’s repo‑rate movement with growth in domestic sales of passenger vehicles—cars and utility vehicles—and two‑wheelers. The resulting charts show that interest‑rate shifts have limited influence on auto sales, with sales growth patterns not consistently aligning with rate hikes or cuts.

For instance, in FY20 the RBI cut rates by 185 basis points, yet sales of both cars and two‑wheelers fell almost 18%. The decline coincided with the COVID‑19 lockdown in the fiscal year’s final week and was driven by sharp price rises from stricter safety and emission rules, as well as overall weakness in financing and liquidity. In FY23, the RBI raised rates six times (250 basis points in total), yet sales of cars and two‑wheelers jumped, partly due to a rebound after two pandemic‑hit years.

FY26 provided a cleaner test: between February and June 2025 the RBI cut the repo rate by 100 basis points, yet passenger‑vehicle sales fell 1.4% in April‑June and 1.5% in July‑September. In September 2025 GST on small cars and motorcycles up to 350cc was reduced from 28% to 18%, and PV sales rose 20.6% in the October‑December quarter. The surge was supported by the festive season, income‑tax relief from Budget 2025, and the earlier rate cuts, yet six months of cheaper loans left car sales flat to negative until sticker prices fell.

A 25‑basis‑point hike adds about ₹105 to the average car EMI. The average auto loan in India is ₹8.6 lakh, and a five‑year loan at 9% would see the EMI rise from ₹17,852 to ₹17,957. The marginal increase of ₹105 per month is unlikely to deter aspirational buyers, many of whom plan and save in advance for their first vehicle. Additionally, a steady replacement cycle of 12‑15 years sustains annual demand as older vehicles are traded for newer ones.

In summary, while interest rates matter at the margin and significantly affect banks and NBFCs that finance vehicles, they do not dominate vehicle demand. Two other factors—sticker price and replacement demand—play more decisive roles. The RBI’s rate moves grab headlines, but the ultimate determinant of sales remains the retail price of the vehicle.
