Mumbai, Sep 6 : The Indian rupee ended flat at 79.84 against the US dollar on Tuesday, due to lack of fresh triggers. "USDINR spot closed flat at 79.84 due to lack of fresh triggers. Corporate inflows and suspected intervention from the RBI kept USDINR capped but at the same time, weakness in Chinese currency did not allow rupee to appreciate. Over the near term, we expect a rangebound price action in USDINR," said Anindya Banerjee, VP, Currency Derivatives & Interest Rate Derivatives at Kotak Securities Ltd. "Range could be 79.50 and 80.10 on spot," Banerjee added. Dollar index, which gauges the the strength of greenback against the basket of six major currencies, was at 109.797. Brent crude oil prices were at $92.81 a barrel by the closing of Indian market hours.
