MUMBAI (Reuters) - The rupee weakened for a second session on Tuesday as the dollar rallied broadly on hopes U.S. lawmakers would agree on a deal to raise the country's debt limit, averting an immediate default.
The plan being negotiated by U.S. Senate leaders would end a partial government shutdown and raise the debt ceiling by enough to cover the nation's borrowing needs at least through mid-February 2014, a source familiar with the negotiations told Reuters.
The index of the dollar against six major currencies rose to a one-month high of 80.678, pushing the rupee to session lows in the last hour of trade.
"The market is not positioned big yet for the 17th of October. It is not ready for a repeat of the 2008 mayhem with more intensity," said Vikas Babu Chittiprolu, a senior foreign exchange dealer with state-run Andhra Bank.
"The deal will likely go through last minute but either way the rupee will weaken further. If the deal doesn't go through, the fall would be much more," he added.
