The BSE Sensex fell on Friday as private sector lenders were hit after the government and the Reserve Bank of India (RBI) said they would investigate allegations of money laundering practices, while S&P's comments that weaker growth was constraining ratings also weighed.

Broader sentiment was also hit after an analyst at Standard and Poor's said the slowdown in India's economic growth was less supportive for the country's sovereign credit ratings.
Investors are now gearing up for the Reserve Bank of India's policy review on Tuesday amid expectations that the central bank will lower interest rates by 25 basis points.
"The central bank will not do more than 25 bps, but what will be important is what RBI says with respect to its future stance. I don't think RBI will try to give a sense that they are going to be outright accommodative," said Dhananjay Sinha, co-head, institutional research, Emkay Global.
The benchmark BSE Sensex fell 0.73 percent, or 142.88 points, to 19,427.56.
The index fell 1.3 percent for the week, marking its sixth weekly drop in last seven.
The broader Nifty fell 0.62 percent, or 36.35 points, to 5,872.60, closing below the psychologically important 5,900 level and down 1.22 percent for the week.
Goldman Sachs said the allegations, if proven, could slow growth for private sector lenders.
Sentiment was also hit after S&P's senior director Kim Eng Tan said the government may find it challenging to meet the revenue projections in its 2013/14 budget.
