Forex dealers said bleeding domestic stocks and a weakening bond market firming up the dollar in turn, weighed upon the rupee.
Foreign institutional investors pulled out Rs 86.66 crore (Rs 866.6 million) from local stocks on Monday, as per provisional BSE data.
"The pressure on rupee was mainly built due to fag-end buying by some foreign banks and importers.
"Bond markets were seen slumping, which in turn pushed up the dollar and hit the local currency.
"Capital outflows by FIIs, coupled with weakening stocks also marred the rupee sentiment," said Srinivasa Raghavan, executive vice-president (Treasury) at private-sector Dhanlaxmi Bank.
The rupee commenced weak on Monday at 56.55, below Friday's close of 56.55
