The Indian rupee fell amid weakness of the euro as worries over the European debt crisis deepened following Standard & Poor's downgrade of Italy's sovereign rating.
Analysts said large IT companies benefit by weakness in the rupee as it helps in improving their profit margins.
IT companies like TCS, Infosys, Wipro and HCL Technologies earn a major chunk of their revenues from the US in dollars.
