The BSE benchmark Sensex plunged 525 points to a five-week low of 18,197.20 during the week under review on heavy selling pressure on fears of negative impact on corporate growth due to interest rate hike by the RBI amid maintaining hawkish stance on further monetary actions.
Global turmoil due to US debt tensions and a weaker-than-expected US economic data too affected the market mood.
Traders as well as investors kept themselves away from making major purchases due to postponement of a vote in the House of Representatives on a US debt plan.
The Reserve Bank of India in its first quarter review of the monetary policy 2011-12, on July 26, hiked the short-term lending (repo) and borrowing rates (reverse repo) by 50 basis points to tame high inflation, making all personal and corporate loans more expensive.
The apex bank has also revised its fiscal-end inflation projection to 7 per cent from 6 per cent earlier.
Interest rate sensitive stocks from realty, banking and auto segments bore the brunt of heavy selling.
Offloading long positions in view of the expiry of July contract too aggravated the situation.
Metal stocks were also at the receiving end, following a fall in metal prices at the London Metal Exchange (LME).
