Snapping its two-day gaining streak, the rupee today ended lower by 14 paise against the US currency following month-end dollar demand amid some weakness in equities.

In last two trading sessions, the rupee had gained 64 paise or 1.40 per cent against the dollar.
Dealers said month-end dollar demand from importers, mainly oil refiners, to meet their monthly requirements as well as over 135 point fall in the benchmark Sensex in afternoon trade, pushed the rupee to day's low of 45.28.
But sustained heavy portfolio investment in local stocks and fag-end recovery in equities, where the Sensex ended lower by a mere over 12 points, helped the rupee to rebound at the fag end to settle the day at 45.15/16.
