At the Interbank Foreign Exchange (Forex) market, the domestic unit commenced lower at 54.87 a dollar from previous close of 54.77 and immediately touched a low of 55.00.
About USD 150 million in FII flows and some dollar selling helped rupee later recover to touch a high of 54.80. It finally settled slightly weak at 54.88 - a fall of 11 paise or 0.20 per cent. This is the worst show by the local currency since its 55-paise drop on May 10.
The dollar index strengthened today by 0.20 per cent against a basket of six major currencies, trading at its best levels in 10 months after reports said a Federal Reserve official has projected the possible timing of a winding down of the Fed's bond buying programme.
The bond purchases inject fresh dollar in the market and a slower rate of buying is expected to increase dollar demand as supply gets reduced, said treasury head of a bank.
Pramit Brahmbhatt, CEO, Alpari Financial Services (India) said: "Rupee traded low against dollar although the fall was capped by the Indian shares that traded positively. The dollar index traded positively as Euro continued to trade weak against the mighty."
Resistance for USDINR (Spot) pair is at 55.15 and the trading range for the USD/INR pair is expected to be within 54.70 to 55.20, he added.
