The Indian rupee slumped past the 65 per dollar mark on Tuesday nearing its all-time low and paring its gains in the last two sessions, as concerns weighed heavily in the financial markets on the expected increase in government's subsidy burden following the passage of the food security bill.
The rupee fell to as low as 65.45 per dollar after opening the session at 65.01, compared with its Monday's close of 64.31.
India's equity benchmark Sensex was trading at 18,347.53 points, down 1.13 per cent.
The Indian currency had touched its lifetime low of 65.56 per dollar on 22 August.
