Reuters Market Eye - The rupee falls to 63.42/44 from its previous close of 62.475/485, after earlier hitting a session low of 63.50, its lowest since September 17.
The rupee falls tracking weaker local shares and reflecting dollar demand from state-run oil companies, traders say.
India's economic affairs secretary Arvind Mayaram said last week state-run oil companies were sourcing 30-40 percent of the dollar needs in markets and not via the special window provided by the central bank.
However, traders warn continued weakness could spark intervention from the central bank, which was spotted selling dollars on Friday.
