BSE Auto index down nearly 1% with MRF falling 1.72% and Maruti Suzuki 1.58%. Ashok Leyland, Tube Investments, Exide, and Motherson also decline amid a broad market sell-off.

The BSE Auto index fell by nearly 1 percent in early trade on Monday, 13 July 2026, as automobile stocks came under broad-based pressure alongside the wider market sell-off triggered by fresh United States and Iran tensions. Almost every major constituent traded lower, making the fall in the BSE Auto index one of the sharpest sectoral declines of the session.

MRF led the losers, falling 1.72 percent to Rs 1,32,083.30, followed by Maruti Suzuki, down 1.58 percent to Rs 13,640.00.

BSE Auto Index: Top Losers on 13 July 2026

The intraday losers list spans tyre makers, passenger vehicle majors, commercial vehicle players, and auto ancillaries, confirming that the current weakness in the BSE Auto index is affecting the entire automotive value chain rather than just one single isolated segment.

Ashok Leyland recorded by far the heaviest volume among the losers at 4.75 lakh shares, suggesting institutional repositioning in commercial vehicles rather than thin, retail-led selling. Two-wheeler majors Hero MotoCorp and Eicher Motors were comparatively resilient, down 0.94 percent and 0.91 percent respectively, while TVS Motor held up the best among the entire pack, falling only 0.66 percent so far in early trade today.

Why Is the BSE Auto Index Falling Today

1. Crude Oil Surge Raises Input and Fuel Cost Worries

Brent crude jumped over 3 percent to around 78.35 dollars a barrel on Middle East tensions. Higher crude directly raises input costs for tyre and rubber-heavy components while also pushing up fuel prices, both of which weigh on demand sentiment and margins across the BSE Auto index.

2. Broader Risk-Off Sentiment

With the Sensex crashing over 700 points at its low and India VIX spiking nearly 10 percent, cyclical sectors like autos, which are sensitive to consumer discretionary spending, tend to see sharper sell-offs than defensives during high-volatility sessions.

3. Commercial Vehicle Demand Sensitivity

Ashok Leyland’s notably outsized volume and price decline reflects how commercial vehicle stocks remain particularly sensitive to fuel cost inflation, since higher diesel prices directly squeeze fleet operator margins and can delay replacement purchase cycles, adding further pressure to the BSE Auto index. Commercial vehicle order books, which are typically booked months in advance, are less immediately sensitive to daily fuel price swings, but sustained cost inflation over a full quarter can still delay fleet renewal decisions by transport fleet operators watching their operating margins very closely each passing month.

What Should Investors Watch in the BSE Auto Index Now

Investors should track crude oil trends closely, since a sustained rise beyond 80 dollars a barrel would likely keep pressuring input costs and fuel prices simultaneously, a double drag on the earnings outlook priced into the BSE Auto index. Monthly volume data for July, due early next month, will also be an important signal on whether the recent festive-linked optimism in retail sales is holding up.

From a positioning standpoint, two-wheeler names with lower crude sensitivity and better rural demand exposure have shown relative resilience today and may continue to outperform commercial vehicle and tyre names if the input cost pressure on the BSE Auto index persists through the week. Passenger vehicle makers with a diversified fuel-type portfolio, including hybrids and electric variants, could also see relatively better sentiment if crude prices stay elevated for an extended period, since buyers may increasingly weight running costs into their purchase decisions during periods of sustained fuel price volatility like the present one currently unfolding.
