Mumbai: The Bombay Stock Exchange (BSE) benchmark Sensex plunged by 146 points to below 18,000-level on Thursday as the RBI increased key policy rates for the 10 time in a row in its bid to tame rising inflation.

The key index of the BSE declined 100 points in the opening trade and declined further during the day. It finally settled the day at 17,985.88, a sharp loss of 146.36 points or 0.81 per cent from its last close

The NSE 50-share Nifty also fell by 50.75 points or 0.93 per cent to finish at 5,396.75.

Market participants, however, said that stocks were not weighed down by the Reserve Bank of India's (RBI) decision to hike short-term lending and borrowing by 25 basis points each as the increase was already accounted for by bourses.

 "Market gave thumbs up to the RBI announcement as it surged sharply upwards to gain some lost ground. Good buying was witnessed in banking stocks which further aided the uptrend," Bonanza Portfolio Sr Research analyst Shanu Goel said.
The uptrend was short-lived in the absence of optimistic signals regarding growth and curbing inflation, he added.

Investors battered stocks across counters but it was the IT, capital goods, metal shares that bore brunt of selling amid particularly weak global trends.
