According to latest SIAM data, most of the major segments, including scooters, motorcycles and cars, witnessed record decline December sales as the automobile sector continued to bear the brunt of negative consumer sentiments in the wake of the ban of Rs 500 and Rs 1,000 banknotes announced in November. Vehicle sales across categories registered a decline of 18.66 per cent last month at 12,21,929 units, from 15,02,314 units in December 2015, as per Society of Indian Automobile Manufacturers (SIAM). "This is the highest decline across all categories since December 2000, when there was a drop of 21.81 per cent in sales. The reason is largely due to the negative consumer sentiment in the market due to demonetisation," SIAM Director General Vishnu Mathur told reporters here. Except for the light commercial vehicles segment, which saw a growth of 1.15 per cent at 31,178 units, all the other categories of the industry saw decline in sales in December, he added. Mathur, however, said the drop in sales is temporary but how sales pick up would depend a lot on "how the Bugdet comes up with steps that will boost consumer sentiments and increase disposable income besides improving the overall economy." Domestic car sales were at 1,58,617 units last month as against 1,72,671 units in December 2015, down 8.14 per cent. It was the lowest rate since April 2014 when sales declined by 10.15 per cent. Passenger vehicle sales declined 1.36 per cent to 2,27,824 units in December 2016 from 2,30,959 units in the year-ago month. The previous biggest decline in sales witnessed by the segment was in October 2014 with a drop of 7.52 per cent. Similarly, total two-wheeler sales in December also witnessed the steepest decline since SIAM started recording data in 1997. It tanked 22.04 per cent to 9,10,235 units compared with 11,67,621 units in the year-ago month. Likewise, scooter sales, which is mostly urban-centric, also saw the biggest decline in over 15 years, falling 26.38 per cent at 2,84,384 units in December 2016 as against 3,86,305 units in the year-ago month. The previous biggest decline of 27.05 per cent was recorded in March 2001. Motorcycle sales also saw the biggest decline in eight years last month at 5,61,690 units from 7,24,795 units a year earlier, down 22.5 per cent, SIAM said. The segment witnessed biggest drop of 23.07 per cent in December 2008. "Almost half of two-wheelers sales comes from rural markets, which have been hit hard by demonetisation," Mathur said while explaining why the segment has suffered a big blow in December. Sales of commercial vehicles were down 5.06 per cent at 53,966 units in December 2016 as against 56,840 units in the same month in 2015, SIAM said. Mathur said whatever sales December witnessed were "driven by the largest discounts ever that the industry has seen." He further said that moderation in sales in the auto industry is expected to continue this month as well as consumers defer purchases on Budget expectations. "At present, there is stock inventory of almost one month in the auto industry, which will have to be cleared," he added. When asked if SIAM would revise its growth forecast for the ongoing fiscal for passenger vehicles, considering the drop in sales in November and December, he said the industry body hasn't looked at the matter yet. "However, with the way things are going and if the Budget doesn't bring big steps to boost consumer sentiments, we may miss our forecast," Mathur said. Last September, SIAM had revised upward its growth estimate for passenger vehicles for the ongoing fiscal to 10-12 per cent. The segment was originally pegged to grow at 11-13 per cent but was later revised downward to 6-8 per cent. Mathur said that the auto industry hasn't yet benefited from a good monsoon and 7th Pay Commission payouts and a lot would depend on the Budget going forward. According to SIAM data, in the cars segment, market leader Maruti Suzuki India saw its domestic sales decline by 10.93 per cent in December at 81,092 units as against 91,043 units in the same month a year ago. Similarly, rival Hyundai Motor India also witnessed a decline of 10.95 per cent at 33,037 units last month as against 37,101 units in December 2015.

In the motorcycles segment, market leader Hero MotoCorp saw its sales dip by 28.98 per cent to 2,79,448 units last month as against 3,93,495 units in December 2015.
