(Reuters) - The BSE Sensex fell about 1 percent on Friday with the Nifty closing below its 200-day moving average for the first time in nearly three weeks as banks declined after Reserve Bank of India (RBI) chief's comments on inflation being still high.
RBI Governor Raghuram Rajan also said on Thursday central banks risk sparking new crises by keeping their loose policy in place for too long.
Investors were cautious ahead of the June quarter current account deficit numbers due on Monday. India's current account deficit is expected to rise from the previous three-month period before easing due to a sharp fall in gold imports and improving exports.
