MUMBAI (Reuters) - The Sensex fell over 1 percent on Wednesday, as a slump in the rupee reignited fears of foreign investor selling, while lenders declined after the Reserve Bank of India (RBI) mandated them to increase provisioning against their currency exposure.
The falls also tracked global shares as signs of slowing Chinese growth and escalating political tensions in Portugal, one of the euro zone's crisis hot-spots, spooked investors.
The Sensex has now erased its entire gain for the year and is down 1.28 percent, after hitting a 20,443.62 peak on May 20. The Nifty is down 2.27 percent.
The shares have been hit hard along with other emerging markets due to fears about an early end to U.S. monetary stimulus and signs of a weakening Chinese economy.
Foreign investors have sold nearly 98.2 billion rupees in domestic shares since the start of June, as per regulatory data.
