Mumbai, Oct. 12 -- The key equity benchmarks ended with substantial losses on Monday. Investor sentiment remained cautious ahead of the release of India's inflation data later in the day. Although crude oil prices retreated, they remained above $105 a barrel, keeping inflationary concerns in focus. A sharp rise in Indian bond yields further weighed on market sentiment.
