M&M Chief Executive (auto division) Pravin Shah said: "While we expected an improved auto industry performance on the back of festive season and other positive parameters such as rural demand and interest rates softening, the sudden announcement of demonetisation has brought in an immediate disruption and uncertainty."
Although, demonetisation is a good and welcoming step in the mid to long term, this has dampened overall sentiments leading to postponed buying thereby resulting in a major dip in volumes during November, he added.
"This is significant as the automotive industry had just started experiencing stability post a long and tough period of uncertainty," Shah said.
