The Sensex had closed 61 points lower at 33,856 on Tuesday
The BSE Sensex fell as much as 276 points on Wednesday to hit an intraday low of 33,580, dragged down by banking and energy stocks. The National Stock Exchange (NSE) benchmark index Nifty lost 90 points to hit an intraday low below the 10,350 mark in afternoon deals. Declines during Wednesday's session were led by banking, energy and FMCG stocks. Weakness was also seen in banking stocks, a day after the Reserve Bank of India (RBI) barred all lenders from issuing letters of undertaking - a form of credit guarantee at the heart of a major fraud. Revelations by Punjab National Bank of additional exposure in an alleged fraud further dampened sentiment.
