A renewed surge in crude oil towards $100 a barrel rattled Indian financial markets on Tuesday, sending the rupee to its steepest fall in nearly two months and dragging benchmark equity indices to three-month lows. The rupee ended at 94.82 against the dollar, down 34 paise from its previous close, according to Bloomberg, snapping a week-long rally fuelled by strong FCNR(B) inflows. The currency had gained about 1% over the preceding seven days.
